4.1 Therapeutic indications 
 
Imatinib Teva B.V. is indicated for the treatment of 
• Paediatric patients with newly diagnosed Philadelphia chromosome (bcr-abl) positive (Ph+) chronic 

myeloid leukaemia (CML) for whom bone marrow transplantation is not considered as the first line of 
treatment. 

• Paediatric patients with Ph+ CML in chronic phase after failure of interferon-alpha therapy, or in 
accelerated phase or blast crisis. 

• Adult patients with Ph+ CML in blast crisis. 
• Adult and paediatric patients with newly diagnosed Philadelphia chromosome positive acute 

lymphoblastic leukaemia (Ph+ ALL) integrated with chemotherapy. 
• Adult patients with relapsed or refractory Ph+ ALL as monotherapy. 
• Adult patients with myelodysplastic/myeloproliferative diseases (MDS/MPD) associated with platelet-

derived growth factor receptor (PDGFR) gene re-arrangements. 
• Adult patients with advanced hypereosinophilic syndrome (HES) and/or chronic eosinophilic 

leukaemia (CEL) with FIP1L1-PDGFRα rearrangement.

The effect of imatinib on the outcome of bone marrow transplantation has not been determined. 
 
Imatinib Teva B.V. is indicated for 
• The treatment of adult patients with Kit (CD 117) positive unresectable and/or metastatic malignant 

gastrointestinal stromal tumours (GIST). 
• The adjuvant treatment of adult patients who are at significant risk of relapse following resection of 

Kit (CD117)-positive GIST. Patients who have a low or very low risk of recurrence should not receive 
adjuvant treatment. 

• The treatment of adult patients with unresectable dermatofibrosarcoma protuberans (DFSP) and adult 
patients with recurrent and/or metastatic DFSP who are not eligible for surgery. 

 
In adult and paediatric patients, the effectiveness of imatinib is based on overall haematological and 
cytogenetic response rates and progression-free survival in CML, on haematological and cytogenetic 
response rates in Ph+ ALL, MDS/MPD, on haematological response rates in HES/CEL and on objective 
response rates in adult patients with unresectable and/or metastatic GIST and DFSP and on recurrence-free 
survival in adjuvant GIST. The experience with imatinib in patients with MDS/MPD associated with PDGFR 
gene re-arrangements is very limited (see section 5.1). There are no controlled trials demonstrating a clinical 
benefit or increased survival for these diseases. 
 
4.2 Posology and method of administration 
 
Therapy should be initiated by a physician experienced in the treatment of patients with haematological 
malignancies and malignant sarcomas, as appropriate. 
 
For doses of 400 mg and above (see dosage recommendation below) a 400 mg film-coated tablet is available. 
 
For doses other than 400 mg and 800 mg (see dosage recommendation below) a 100 mg film-coated tablet is 
available. 
 
The prescribed dose should be administered orally with a meal and a large glass of water to minimise the risk 
of gastrointestinal irritations. Doses of 400 mg or 600 mg should be administered once daily, whereas a daily 
dose of 800 mg should be administered as 400 mg twice a day, in the morning and in the evening. 
 
For patients unable to swallow the film-coated tablets, the tablets may be dispersed in a glass of still water or 
apple juice. The required number of tablets should be placed in the appropriate volume of beverage 
(approximately 50 ml for a 100 mg tablet, and 200 ml for a 400 mg tablet) and stirred with a spoon. The 
suspension should be administered immediately after complete disintegration of the tablet(s). 
 
Posology for CML in adult patients 
The recommended dose of Imatinib Teva B.V. is 600 mg/day for adult patients in blast crisis. Blast crisis is 
defined as blasts ≥ 30% in blood or bone marrow or extramedullary disease other than hepatosplenomegaly. 
  
Treatment duration: In clinical trials, treatment with imatinib was continued until disease progression. The 
effect of stopping treatment after the achievement of a complete cytogenetic response has not been 
investigated. 
 
Dose increases from 600 mg to a maximum of 800 mg (given as 400 mg twice daily) in patients with blast 
crisis may be considered in the absence of severe adverse drug reaction and severe non-leukaemia-related 
neutropenia or thrombocytopenia in the following circumstances: disease progression (at any time); failure to 
achieve a satisfactory haematological response after at least 3 months of treatment; failure to achieve a 
cytogenetic response after 12 months of treatment; or loss of a previously achieved haematological and/or 
cytogenetic response. Patients should be monitored closely following dose escalation given the potential for 
an increased incidence of adverse reactions at higher dosages.

Dosing for children should be on the basis of body surface area (mg/m2). The dose of 340 mg/m2 daily is 
recommended for children with chronic phase CML and advanced phase CML (not to exceed the total dose 
of 800 mg). Treatment can be given as a once daily dose or alternatively the daily dose may be split into two 
administrations – one in the morning and one in the evening. The dose recommendation is currently based on 
a small number of paediatric patients (see sections 5.1 and 5.2). There is no experience with the treatment of 
children below 2 years of age. 
 
Dose increases from 340 mg/m2 daily to 570 mg/m2 daily (not to exceed the total dose of 800 mg) may be 
considered in children in the absence of severe adverse drug reaction and severe non-leukaemia-related 
neutropenia or thrombocytopenia in the following circumstances: disease progression (at any time); failure to 
achieve a satisfactory haematological response after at least 3 months of treatment; failure to achieve a 
cytogenetic response after 12 months of treatment; or loss of a previously achieved haematological and/or 
cytogenetic response. Patients should be monitored closely following dose escalation given the potential for 
an increased incidence of adverse reactions at higher dosages. 
 
Posology for Ph+ ALL in adult patients 
The recommended dose of Imatinib Teva B.V. is 600 mg/day for adult patients with Ph+ ALL. 
Haematological experts in the management of this disease should supervise the therapy throughout all phases 
of care. 
 
Treatment schedule: On the basis of the existing data, imatinib has been shown to be effective and safe when 
administered at 600 mg/day in combination with chemotherapy in the induction phase, the consolidation and 
maintenance phases of chemotherapy (see section 5.1) for adult patients with newly diagnosed Ph+ ALL. 
The duration of imatinib therapy can vary with the treatment programme selected, but generally longer 
exposures to imatinib have yielded better results. 
 
For adult patients with relapsed or refractory Ph+ALL imatinib monotherapy at 600 mg/day is safe, effective 
and can be given until disease progression occurs. 
 
Posology for Ph+ ALL in children 
Dosing for children should be on the basis of body surface area (mg/m2). The dose of 340 mg/m2 daily is 
recommended for children with Ph+ ALL (not to exceed the total dose of 600 mg). 
 
Posology for MDS/MPD 
The recommended dose of Imatinib Teva B.V. is 400 mg/day for adult patients with MDS/MPD. 
 
Treatment duration: In the only clinical trial performed up to now, treatment with imatinib was continued 
until disease progression (see section 5.1). At the time of analysis, the treatment duration was a median of 47 
months (24 days - 60 months). 
 
Posology for HES/CEL 
The recommended dose of Imatinib Teva B.V. is 100 mg/day for adult patients with HES/CEL. 
 
Dose increase from 100 mg to 400 mg may be considered in the absence of adverse drug reactions if 
assessments demonstrate an insufficient response to therapy. 
 
Treatment should be continued as long as the patient continues to benefit. 
 
Posology for GIST 
The recommended dose of Imatinib Teva B.V. is 400 mg/day for adult patients with unresectable and/or 
metastatic malignant GIST. 
 
Limited data exist on the effect of dose increases from 400 mg to 600 mg or 800 mg in patients progressing 
at the lower dose (see section 5.1).

Treatment duration: In clinical trials in GIST patients, treatment with imatinib was continued until disease 
progression. At the time of analysis, the treatment duration was a median of 7 months (7 days to 13 months). 
The effect of stopping treatment after achieving a response has not been investigated. 
 
The recommended dose of Imatinib Teva B.V. is 400 mg/day for the adjuvant treatment of adult patients 
following resection of GIST. Optimal treatment duration is not yet established. Length of treatment in the 
clinical trial supporting this indication was 36 months (see section 5.1). 
 
Posology for DFSP 
The recommended dose of Imatinib Teva B.V. is 800 mg/day for adult patients with DFSP. 
 
Dose adjustment for adverse reactions 
Non-haematological adverse reactions 
If a severe non-haematological adverse reaction develops with imatinib use, treatment must be withheld until 
the event has resolved. Thereafter, treatment can be resumed as appropriate depending on the initial severity 
of the event. 
 
If elevations in bilirubin > 3 x institutional upper limit of normal (IULN) or in liver transaminases > 5 x 
IULN occur, imatinib should be withheld until bilirubin levels have returned to < 1.5 x IULN and 
transaminase levels to < 2.5 x IULN. Treatment with imatinib may then be continued at a reduced daily dose. 
In adults the dose should be reduced from 400 to 300 mg or from 600 to 400 mg, or from 800 mg to 600 mg, 
and in children from 340 to 260 mg/m2/day.

Special populations 
Paediatric use: There is no experience in children with CML below 2 years of age and with Ph+ALL below 
1 year of age (see section 5.1). There is very limited experience in children with MDS/MPD, DFSP, GIST 
and HES/CEL. 
 
The safety and efficacy of imatinib in children with MDS/MPD, DFSP, GIST and HES/CEL aged less than 
18 years of age have not been established in clinical trials. Currently available published data are 
summarised in section 5.1 but no recommendation on a posology can be made. 
 
Hepatic insufficiency: Imatinib is mainly metabolised through the liver. Patients with mild, moderate or 
severe liver dysfunction should be given the minimum recommended dose of 400 mg daily. The dose can be 
reduced if not tolerated (see sections 4.4, 4.8 and 5.2). 
 
Liver dysfunction classification: 
 
Liver dysfunction Liver function tests 
Mild Total bilirubin: = 1.5 ULN 

AST: >ULN (can be normal or <ULN if total 
bilirubin is >ULN) 

Moderate Total bilirubin: >1.5-3.0 ULN 
AST: any 

Severe Total bilirubin: >3-10 ULN 
AST: any 

ULN = upper limit of normal for the institution 
AST = aspartate aminotransferase 
 
Renal insufficiency: Patients with renal dysfunction or on dialysis should be given the minimum 
recommended dose of 400 mg daily as starting dose. However, in these patients caution is recommended. 
The dose can be reduced if not tolerated. If tolerated, the dose can be increased for lack of efficacy (see 
sections 4.4 and 5.2).

Older people: Imatinib pharmacokinetics have not been specifically studied in older people. No significant 
age-related pharmacokinetic differences have been observed in adult patients in clinical trials which included 
over 20% of patients age 65 and older. No specific dose recommendation is necessary in older people. 
 
4.3 Contraindications 
 
Hypersensitivity to the active substance or to any of the excipients listed in section 6.1. 
 
4.4 Special warnings and precautions for use 
 
When imatinib is co-administered with other medicinal products, there is a potential for drug interactions. 
Caution should be used when taking imatinib with protease inhibitors, azole antifungals, certain macrolides 
(see section 4.5), CYP3A4 substrates with a narrow therapeutic window (e.g. cyclosporine, pimozide, 
tacrolimus, sirolimus, ergotamine, diergotamine, fentanyl, alfentanil, terfenadine, bortezomib, docetaxel, 
quinidine) or warfarin and other coumarin derivatives (see section 4.5). 
 
Concomitant use of imatinib and medicinal products that induce CYP3A4 (e.g. dexamethasone, phenytoin, 
carbamazepine, rifampicin, phenobarbital or Hypericum perforatum, also known as St. John’s Wort) may 
significantly reduce exposure to imatinib, potentially increasing the risk of therapeutic failure. Therefore, 
concomitant use of strong CYP3A4 inducers and imatinib should be avoided (see section 4.5). 
 
Hypothyroidism 
Clinical cases of hypothyroidism have been reported in thyroidectomy patients undergoing levothyroxine 
replacement during treatment with imatinib (see section 4.5). Thyroid-stimulating hormone (TSH) levels 
should be closely monitored in such patients. 
 
Hepatotoxicity 
Metabolism of imatinib is mainly hepatic, and only 13% of excretion is through the kidneys. In patients with 
hepatic dysfunction (mild, moderate or severe), peripheral blood counts and liver enzymes should be 
carefully monitored (see sections 4.2, 4.8 and 5.2). It should be noted that GIST patients may have hepatic 
metastases which could lead to hepatic impairment. 
 
Cases of liver injury, including hepatic failure and hepatic necrosis, have been observed with imatinib. When 
imatinib is combined with high dose chemotherapy regimens, an increase in serious hepatic reactions has 
been detected. Hepatic function should be carefully monitored in circumstances where imatinib is combined 
with chemotherapy regimens also known to be associated with hepatic dysfunction (see section 4.5 and 4.8). 
 
Fluid retention 
Occurrences of severe fluid retention (pleural effusion, oedema, pulmonary oedema, ascites, superficial 
oedema) have been reported in approximately 2.5% of newly diagnosed CML patients taking imatinib. 
Therefore, it is highly recommended that patients be weighed regularly. An unexpected rapid weight gain 
should be carefully investigated and if necessary appropriate supportive care and therapeutic measures 
should be undertaken. In clinical trials, there was an increased incidence of these events in older people and 
those with a prior history of cardiac disease. Therefore, caution should be exercised in patients with cardiac 
dysfunction. 
 
Patients with cardiac disease 
Patients with cardiac disease, risk factors for cardiac failure or history of renal failure should be monitored 
carefully, and any patient with signs or symptoms consistent with cardiac or renal failure should be evaluated 
and treated. 
 
In patients with hypereosinophilic syndrome (HES) with occult infiltration of HES cells within the 
myocardium, isolated cases of cardiogenic shock/left ventricular dysfunction have been associated with HES 
cell degranulation upon the initiation of imatinib therapy. The condition was reported to be reversible with 
the administration of systemic steroids, circulatory support measures and temporarily withholding imatinib.

As cardiac adverse events have been reported uncommonly with imatinib, a careful assessment of the 
benefit/risk of imatinib therapy should be considered in the HES/CEL population before treatment initiation. 
 
Myelodysplastic/myeloproliferative diseases with PDGFR gene re-arrangements could be associated with 
high eosinophil levels. Evaluation by a cardiology specialist, performance of an echocardiogram and 
determination of serum troponin should therefore be considered in patients with HES/CEL, and in patients 
with MDS/MPD associated with high eosinophil levels before imatinib is administered. If either is abnormal, 
follow-up with a cardiology specialist and the prophylactic use of systemic steroids (1–2 mg/kg) for one to 
two weeks concomitantly with imatinib should be considered at the initiation of therapy. 
 
Gastrointestinal haemorrhage 
In the study in patients with unresectable and/or metastatic GIST, both gastrointestinal and intra-tumoural 
haemorrhages were reported (see section 4.8). Based on the available data, no predisposing factors (e.g. 
tumour size, tumour location, coagulation disorders) have been identified that place patients with GIST at a 
higher risk of either type of haemorrhage. Since increased vascularity and propensity for bleeding is a part of 
the nature and clinical course of GIST, standard practices and procedures for the monitoring and 
management of haemorrhage in all patients should be applied. 
 
In addition, gastric antral vascular ectasia (GAVE), a rare cause of gastrointestinal haemorrhage, has been 
reported in post-marketing experience in patients with CML, ALL and other diseases (see section 4.8). When 
needed, discontinuation of Imatinib Teva B.V. treatment may be considered. 
 
Tumour lysis syndrome 
Due to the possible occurrence of tumour lysis syndrome (TLS), correction of clinically significant 
dehydration and treatment of high uric acid levels are recommended prior to initiation of imatinib (see 
section 4.8). 
 
Hepatitis B reactivation 
Reactivation of hepatitis B in patients who are chronic carriers of this virus has occurred after these patients 
received BCR-ABL tyrosine kinase inhibitors. Some cases resulted in acute hepatic failure or fulminant 
hepatitis leading to liver transplantation or a fatal outcome. 
 
Patients should be tested for HBV infection before initiating treatment with Imatinib Teva B.V. Experts in 
liver disease and in the treatment of hepatitis B should be consulted before treatment is initiated in patients 
with positive hepatitis B serology (including those with active disease) and for patients who test positive for 
HBV infection during treatment. Carriers of HBV who require treatment with Imatinib Teva B.V. should be 
closely monitored for signs and symptoms of active HBV infection throughout therapy and for several 
months following termination of therapy (see section 4.8). 
 
Laboratory tests 
Complete blood counts must be performed regularly during therapy with imatinib. Treatment of CML 
patients with imatinib has been associated with neutropenia or thrombocytopenia. However, the occurrence 
of these cytopenias is likely to be related to the stage of the disease being treated and they were more 
frequent in patients with accelerated phase CML or blast crisis as compared to patients with chronic phase 
CML. Treatment with imatinib may be interrupted or the dose may be reduced, as recommended in section 
4.2. 
 
Liver function (transaminases, bilirubin, alkaline phosphatase) should be monitored regularly in patients 
receiving imatinib. 
 
In patients with impaired renal function, imatinib plasma exposure seems to be higher than that in patients 
with normal renal function, probably due to an elevated plasma level of alpha-acid glycoprotein (AGP), an 
imatinib-binding protein, in these patients. Patients with renal impairment should be given the minimum 
starting dose. Patients with severe renal impairment should be treated with caution. The dose can be reduced 
if not tolerated (see section 4.2 and 5.2).

Long-term treatment with imatinib may be associated with a clinically significant decline in renal function. 
Renal function should, therefore, be evaluated prior to the start of imatinib therapy and closely monitored 
during therapy, with particular attention to those patients exhibiting risk factors for renal dysfunction. If renal 
dysfunction is observed, appropriate management and treatment should be prescribed in accordance with 
standard treatment guidelines. 
 
Paediatric population 
There have been case reports of growth retardation occurring in children and pre-adolescents receiving 
imatinib. The long-term effects of prolonged treatment with imatinib on growth in children are unknown. 
Therefore, close monitoring of growth in children under imatinib treatment is recommended (see section 
4.8). 
 
4.5 Interaction with other medicinal products and other forms of interaction 
 
Active substances that may increase imatinib plasma concentrations: 
Substances that inhibit the cytochrome P450 isoenzyme CYP3A4 activity (e.g. protease inhibitors such as 
indinavir, lopinavir/ritonavir, ritonavir, saquinavir, telaprevir, nelfinavir, boceprevir; azole antifungals 
including ketoconazole, itraconazole, posaconazole, voriconazole; certain macrolides such as erythromycin, 
clarithromycin and telithromycin) could decrease metabolism and increase imatinib concentrations. There 
was a significant increase in exposure to imatinib (the mean Cmax and AUC of imatinib rose by 26% and 
40%, respectively) in healthy subjects when it was co-administered with a single dose of ketoconazole (a 
CYP3A4 inhibitor). Caution should be taken when administering imatinib with inhibitors of the CYP3A4 
family. 
 
Active substances that may decrease imatinib plasma concentrations: 
Substances that are inducers of CYP3A4 activity (e.g. dexamethasone, phenytoin, carbamazepine, 
rifampicin, phenobarbital, fosphenytoin, primidone or Hypericum perforatum, also known as St. John’s 
Wort) may significantly reduce exposure to imatinib, potentially increasing the risk of therapeutic failure. 
Pretreatment with multiple doses of rifampicin 600 mg followed by a single 400 mg dose of imatinib resulted 
in decrease in Cmax and AUC(0-∞) by at least 54% and 74%, of the respective values without rifampicin 
treatment. Similar results were observed in patients with malignant gliomas treated with imatinib while 
taking enzyme-inducing anti-epileptic drugs (EIAEDs) such as carbamazepine, oxcarbazepine and 
phenytoin. The plasma AUC for imatinib decreased by 73% compared to patients not on EIAEDs. 
Concomitant use of rifampicin or other strong CYP3A4 inducers and imatinib should be avoided. 
 
Active substances that may have their plasma concentration altered by imatinib 
Imatinib increases the mean Cmax and AUC of simvastatin (CYP3A4 substrate) 2- and 3.5-fold, respectively, 
indicating an inhibition of the CYP3A4 by imatinib. Therefore, caution is recommended when administering 
imatinib with CYP3A4 substrates with a narrow therapeutic window (e.g. cyclosporine, pimozide, 
tacrolimus, sirolimus, ergotamine, diergotamine, fentanyl, alfentanil, terfenadine, bortezomib, docetaxel and 
quinidine). Imatinib may increase plasma concentration of other CYP3A4 metabolised drugs (e.g. triazolo-
benzodiazepines, dihydropyridine calcium channel blockers, certain HMG-CoA reductase inhibitors, i.e. 
statins, etc.). 
 
Because of known increased risks of bleeding in conjunction with the use of imatinib (e.g. haemorrhage), 
patients who require anticoagulation should receive low-molecular-weight or standard heparin, instead of 
coumarin derivatives such as warfarin. 
 
In vitro imatinib inhibits the cytochrome P450 isoenzyme CYP2D6 activity at concentrations similar to those 
that affect CYP3A4 activity. Imatinib at 400 mg twice daily had an inhibitory effect on CYP2D6-mediated 
metoprolol metabolism, with metoprolol Cmax and AUC being increased by approximately 23% (90%CI 
[1.16-1.30]). Dose adjustments do not seem to be necessary when imatinib is co-administrated with CYP2D6 
substrates, however caution is advised for CYP2D6 substrates with a narrow therapeutic window such as 
metoprolol. In patients treated with metoprolol clinical monitoring should be considered.

In vitro, imatinib inhibits paracetamol O-glucuronidation with Ki value of 58.5 micromol/l. This inhibition 
has not been observed in vivo after the administration of imatinib 400 mg and paracetamol 1000 mg. Higher 
doses of imatinib and paracetamol have not been studied. 
 
Caution should therefore be exercised when using high doses of imatinib and paracetamol concomitantly. 
 
In thyroidectomy patients receiving levothyroxine, the plasma exposure to levothyroxine may be decreased 
when imatinib is co-administered (see section 4.4). Caution is therefore recommended. However, the 
mechanism of the observed interaction is presently unknown. 
 
In Ph+ ALL patients, there is clinical experience of co-administering imatinib with chemotherapy (see 
section 5.1), but drug-drug interactions between imatinib and chemotherapy regimens are not well 
characterised. Imatinib adverse events, i.e. hepatotoxicity, myelosuppression or others, may increase and it 
has been reported that concomitant use with L-asparaginase could be associated with increased 
hepatotoxicity (see section 4.8). Therefore, the use of imatinib in combination requires special precaution. 
 
4.6 Fertility, pregnancy and lactation 
 
Women of childbearing potential 
Women of childbearing potential must be advised to use effective contraception during treatment. 
 
Pregnancy 
There are limited data on the use of imatinib in pregnant women. There have been post-marketing reports of 
spontaneous abortions and infant congenital anomalies from women who have taken imatinib. Studies in 
animals have however shown reproductive toxicity (see section 5.3) and the potential risk for the foetus is 
unknown. Imatinib should not be used during pregnancy unless clearly necessary. If it is used during 
pregnancy, the patient must be informed of the potential risk to the foetus. 
 
Breast-feeding 
There is limited information on imatinib distribution on human milk. Studies in two breast-feeding women 
revealed that both imatinib and its active metabolite can be distributed into human milk. The milk plasma 
ratio studied in a single patient was determined to be 0.5 for imatinib and 0.9 for the metabolite, suggesting 
greater distribution of the metabolite into the milk. Considering the combined concentration of imatinib and 
the metabolite and the maximum daily milk intake by infants, the total exposure would be expected to be low 
(~10% of a therapeutic dose). However, since the effects of low-dose exposure of the infant to imatinib are 
unknown, women taking imatinib should not breast-feed. 
 
Fertility 
In non-clinical studies, the fertility of male and female rats was not affected (see section 5.3). Studies on 
patients receiving imatinib and its effect on fertility and gametogenesis have not been performed. Patients 
concerned about their fertility on imatinib treatment should consult with their physician. 
 
4.7 Effects on ability to drive and use machines 
 
Patients should be advised that they may experience undesirable effects such as dizziness, blurred vision or 
somnolence during treatment with imatinib. Therefore, caution should be recommended when driving a car 
or operating machinery. 
 
4.8 Undesirable effects 
 
Patients with advanced stages of malignancies may have numerous confounding medical conditions that 
make causality of adverse reactions difficult to assess due to the variety of symptoms related to the 
underlying disease, its progression, and the co-administration of numerous medicinal products.

In clinical trials in CML, drug discontinuation for drug-related adverse reactions was observed in 2.4% of 
newly diagnosed patients, 4% of patients in late chronic phase after failure of interferon therapy, 4% of 
patients in accelerated phase after failure of interferon therapy and 5% of blast crisis patients after failure of 
interferon therapy. In GIST the study drug was discontinued for drug-related adverse reactions in 4% of 
patients. 
 
The adverse reactions were similar in all indications, with two exceptions. There was more 
myelosuppression seen in CML patients than in GIST, which is probably due to the underlying disease. In 
the study in patients with unresectable and/or metastatic GIST, 7 (5%) patients experienced CTC grade 3/4 
GI bleeds (3 patients), intra-tumoural bleeds (3 patients) or both (1 patient). GI tumour sites may have been 
the source of the GI bleeds (see section 4.4). GI and tumoural bleeding may be serious and sometimes fatal. 
The most commonly reported (≥ 10%) drug-related adverse reactions in both settings were mild nausea, 
vomiting, diarrhoea, abdominal pain, fatigue, myalgia, muscle cramps and rash. Superficial oedemas were a 
common finding in all studies and were described primarily as periorbital or lower limb oedemas. However, 
these oedemas were rarely severe and may be managed with diuretics, other supportive measures, or by 
reducing the dose of imatinib. 
 
When imatinib was combined with high dose chemotherapy in Ph+ ALL patients, transient liver toxicity in 
the form of transaminase elevation and hyperbilirubinaemia were observed. Considering the limited safety 
database, the adverse events thus far reported in children are consistent with the known safety profile in adult 
patients with Ph+ ALL. The safety database for children with Ph+ALL is very limited though no new safety 
concerns have been identified. 
 
Miscellaneous adverse reactions such as pleural effusion, ascites, pulmonary oedema and rapid weight gain 
with or without superficial oedema may be collectively described as “fluid retention”. These reactions can 
usually be managed by withholding imatinib temporarily and with diuretics and other appropriate supportive 
care measures. However, some of these reactions may be serious or life-threatening and several patients with 
blast crisis died with a complex clinical history of pleural effusion, congestive heart failure and renal failure. 
There were no special safety findings in paediatric clinical trials. 
 
Adverse reactions 
Adverse reactions reported as more than an isolated case are listed below, by system organ class and by 
frequency. Frequency categories are defined using the following convention: very common (≥1/10), common 
(≥1/100 to <1/10), uncommon (≥1/1,000 to <1/100), rare (≥1/10,000 to <1/1,000), very rare (<1/10,000), not 
known (cannot be estimated from the available data). 
 
Within each frequency grouping, undesirable effects are presented in order of frequency, the most frequent 
first. 
 
Adverse reactions and their frequencies are reported in Table 1.

* These types of reactions have been reported mainly from post-marketing experience with imatinib. 

This includes spontaneous case reports as well as serious adverse events from ongoing studies, the 
expanded access programmes, clinical pharmacology studies and exploratory studies in unapproved 
indications. Because these reactions are reported from a population of uncertain size, it is not always 
possible to reliably estimate their frequency or establish a causal relationship to imatinib exposure.

1 Pneumonia was reported most commonly in patients with transformed CML and in patients with 
GIST. 

2 Headache was the most common in GIST patients. 
3 On a patient-year basis, cardiac events including congestive heart failure were more commonly 

observed in patients with transformed CML than in patients with chronic CML. 
4 Flushing was most common in GIST patients and bleeding (haematoma, haemorrhage) was most 

common in patients with GIST and with transformed CML (CML-AP and CML-BC). 
5 Pleural effusion was reported more commonly in patients with GIST and in patients with transformed 

CML (CML-AP and CML-BC) than in patients with chronic CML. 
6+7 Abdominal pain and gastrointestinal haemorrhage were most commonly observed in GIST patients. 
8 Some fatal cases of hepatic failure and of hepatic necrosis have been reported. 
9 Musculoskeletal pain during treatment with imatinib or after discontinuation has been observed in 

post-marketing. 
10 Musculoskeletal pain and related events were more commonly observed in patients with CML than in 

GIST patients. 
11 Fatal cases have been reported in patients with advanced disease, severe infections, severe neutropenia 

and other serious concomitant conditions. 
 
Laboratory test abnormalities 
Haematology 
In CML, cytopenias, particularly neutropenia and thrombocytopenia, have been a consistent finding in all 
studies, with the suggestion of a higher frequency at high doses ≥ 750 mg (phase I study). However, the 
occurrence of cytopenias was also clearly dependent on the stage of the disease, the frequency of grade 3 or 
4 neutropenias (ANC < 1.0 x 109/l) and thrombocytopenias (platelet count < 50 x 109/l) being between 4 and 
6 times higher in blast crisis and accelerated phase (59–64% and 44–63% for neutropenia and 
thrombocytopenia, respectively) as compared to newly diagnosed patients in chronic phase CML (16.7% 
neutropenia and 8.9% thrombocytopenia). In newly diagnosed chronic phase CML grade 4 neutropenia 
(ANC < 0.5 x 109/l) and thrombocytopenia (platelet count < 10 x 109/l) were observed in 3.6% and < 1% of 
patients, respectively. The median duration of the neutropenic and thrombocytopenic episodes usually 
ranged from 2 to 3 weeks, and from 3 to 4 weeks, respectively. These events can usually be managed with 
either a reduction of the dose or an interruption of treatment with imatinib, but can in rare cases lead to 
permanent discontinuation of treatment. In paediatric CML patients the most frequent toxicities observed 
were grade 3 or 4 cytopenias involving neutropenia, thrombocytopenia and anaemia. These generally occur 
within the first several months of therapy. 
 
In the study in patients with unresectable and/or metastatic GIST, grade 3 and 4 anaemia was reported in 
5.4% and 0.7% of patients, respectively, and may have been related to gastrointestinal or intra-tumoural 
bleeding in at least some of these patients. Grade 3 and 4 neutropenia was seen in 7.5% and 2.7% of patients, 
respectively, and grade 3 thrombocytopenia in 0.7% of patients. No patient developed grade 4 
thrombocytopenia. The decreases in white blood cell (WBC) and neutrophil counts occurred mainly during 
the first six weeks of therapy, with values remaining relatively stable thereafter. 
 
Biochemistry 
Severe elevation of transaminases (<5%) or bilirubin (<1%) was seen in CML patients and was usually 
managed with dose reduction or interruption (the median duration of these episodes was approximately one 
week). Treatment was discontinued permanently because of liver laboratory abnormalities in less than 1% of 
CML patients. In GIST patients (study B2222), 6.8% of grade 3 or 4 ALT (alanine aminotransferase) 
elevations and 4.8% of grade 3 or 4 AST (aspartate aminotransferase) elevations were observed. Bilirubin 
elevation was below 3%. 
 
There have been cases of cytolytic and cholestatic hepatitis and hepatic failure; in some of them outcome 
was fatal, including one patient on high dose paracetamol.

Hepatitis B reactivation has been reported in association with BCR-ABL TKIs. Some cases resulted in acute 
hepatic failure or fulminant hepatitis leading to liver transplantation or a fatal outcome (see section 4.4). 
 
Reporting of suspected adverse reactions 
Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allows 
continued monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals are asked 
to report any suspected adverse reactions via the national reporting system listed in Appendix V. 
 
4.9 Overdose 
 
Experience with doses higher than the recommended therapeutic dose is limited. Isolated cases of imatinib 
overdose have been reported spontaneously and in the literature. In the event of overdose the patient should 
be observed and appropriate symptomatic treatment given. Generally the reported outcome in these cases 
was “improved” or “recovered”. Events that have been reported at different dose ranges are as follows: 
 
Adult population 
1200 to 1600 mg (duration varying between 1 to 10 days): Nausea, vomiting, diarrhoea, rash, erythema, 
oedema, swelling, fatigue, muscle spasms, thrombocytopenia, pancytopenia, abdominal pain, headache, 
decreased appetite. 
1800 to 3200 mg (as high as 3200 mg daily for 6 days): Weakness, myalgia, increased creatine 
phosphokinase, increased bilirubin, gastrointestinal pain. 
6400 mg (single dose): One case reported in the literature of one patient who experienced nausea, vomiting, 
abdominal pain, pyrexia, facial swelling, decreased neutrophil count, increased transaminases. 
8 to 10 g (single dose): Vomiting and gastrointestinal pain have been reported. 
 
Paediatric population 
One 3-year-old male exposed to a single dose of 400 mg experienced vomiting, diarrhoea and anorexia and 
another 3-year-old male exposed to a single dose of 980 mg experienced decreased white blood cell count 
and diarrhoea. 
 
In the event of overdose, the patient should be observed and appropriate supportive treatment given. 
 
 
5. PHARMACOLOGICAL PROPERTIES 
 
5.1  Pharmacodynamic properties 
 
Pharmacotherapeutic group: Protein kinase inhibitors, ATC code: L01XE01 
 
Mechanism of action 
Imatinib is a small molecule protein-tyrosine kinase inhibitor that potently inhibits the activity of the Bcr-Abl 
tyrosine kinase (TK), as well as several receptor TKs: Kit, the receptor for stem cell factor (SCF) coded for 
by the c-Kit proto-oncogene, the discoidin domain receptors (DDR1 and DDR2), the colony stimulating 
factor receptor (CSF-1R) and the platelet-derived growth factor receptors alpha and beta (PDGFR-alpha and 
PDGFR-beta). Imatinib can also inhibit cellular events mediated by activation of these receptor kinases. 
 
Pharmacodynamic effects 
Imatinib is a protein-tyrosine kinase inhibitor which potently inhibits the Bcr-Abl tyrosine kinase at the in 
vitro, cellular and in vivo levels. The compound selectively inhibits proliferation and induces apoptosis in 
Bcr-Abl positive cell lines as well as fresh leukaemic cells from Philadelphia chromosome positive CML and 
acute lymphoblastic leukaemia (ALL) patients. 
 
In vivo the compound shows anti-tumour activity as a single agent in animal models using Bcr-Abl positive 
tumour cells.

Imatinib is also an inhibitor of the receptor tyrosine kinases for platelet-derived growth factor (PDGF), 
PDGF-R, and stem cell factor (SCF), c-Kit, and inhibits PDGF- and SCF-mediated cellular events. In vitro, 
imatinib inhibits proliferation and induces apoptosis in gastrointestinal stromal tumour (GIST) cells, which 
express an activating kit mutation. Constitutive activation of the PDGF receptor or the Abl protein tyrosine 
kinases as a consequence of fusion to diverse partner proteins or constitutive production of PDGF have been 
implicated in the pathogenesis of MDS/MPD, HES/CEL and DFSP. Imatinib inhibits signalling and 
proliferation of cells driven by dysregulated PDGFR and Abl kinase activity. 
 
Clinical studies in chronic myeloid leukaemia 
The effectiveness of imatinib is based on overall haematological and cytogenetic response rates and 
progression-free survival. There are no controlled trials demonstrating a clinical benefit, such as 
improvement in disease-related symptoms or increased survival. 
 
A large, international, open-label, non-controlled phase II study was conducted in patients with Philadelphia 
chromosome positive (Ph+) CML in blast crisis phase of the disease. In addition, children have been treated 
in two phase I studies and one phase II study. 
 
In all clinical studies 38–40% of patients were ≥ 60 years of age and 10–12% of patients were ≥ 70 years of 
age. 
 
Myeloid blast crisis: 260 patients with myeloid blast crisis were enrolled. 95 (37%) had received prior 
chemotherapy for treatment of either accelerated phase or blast crisis (“pretreated patients”) whereas 165 
(63%) had not (“untreated patients”). The first 37 patients were started at 400 mg, the protocol was 
subsequently amended to allow higher dosing and the remaining 223 patients were started at 600 mg. 
 
The primary efficacy variable was the rate of haematological response, reported as either complete 
haematological response, no evidence of leukaemia (i.e. clearance of blasts from the marrow and the blood, 
but without a full peripheral blood recovery as for complete responses), or return to chronic phase CML. In 
this study, 31% of patients achieved a haematological response (36% in previously untreated patients and 
22% in previously treated patients). The rate of response was also higher in the patients treated at 600 mg 
(33%) as compared to the patients treated at 400 mg (16%, p=0.0220). The current estimate of the median 
survival of the previously untreated and treated patients was 7.7 and 4.7 months, respectively. 
 
Lymphoid blast crisis: a limited number of patients were enrolled in phase I studies (n=10). The rate of 
haematological response was 70% with a duration of 2–3 months.

1 Haematological response criteria (all responses to be confirmed after ≥ 4 weeks):  
CHR: In study 0102 [ANC ≥ 1.5 x 109/l, platelets ≥ 100 x 109/l, no blood blasts, BM blasts < 5% 
and no extramedullary disease]  
NEL Same criteria as for CHR but ANC ≥ 1 x 109/l and platelets ≥ 20 x 109/l  
RTC < 15% blasts BM and PB, < 30% blasts+promyelocytes in BM and PB, < 20% basophils in 
PB, no extramedullary disease other than spleen and liver.  
BM = bone marrow, PB = peripheral blood  
2 Cytogenetic response criteria:  
A major response combines both complete and partial responses: complete (0% Ph+ metaphases), 
partial (1-35%)  
3 Complete cytogenetic response confirmed by a second bone marrow cytogenetic evaluation 
performed at least one month after the initial bone marrow study  

 
Paediatric patients: A total of 26 paediatric patients of age < 18 years with either chronic phase CML (n=11) 
or CML in blast crisis or Ph+ acute leukaemias (n=15) were enrolled in a dose-escalation phase I trial. This 
was a population of heavily pretreated patients, as 46% had received prior BMT and 73% a prior multi-agent 
chemotherapy. Patients were treated at doses of imatinib of 260 mg/m2/day (n=5), 340 mg/m2/day (n=9), 440 
mg/m2/day (n=7) and 570 mg/m2/day (n=5). Out of 9 patients with chronic phase CML and cytogenetic data 
available, 4 (44%) and 3 (33%) achieved a complete and partial cytogenetic response, respectively, for a rate 
of MCyR of 77%. 
 
A total of 51 paediatric patients with newly diagnosed and untreated CML in chronic phase have been 
enrolled in an open-label, multicentre, single-arm phase II trial. Patients were treated with imatinib 340 
mg/m2/day, with no interruptions in the absence of dose limiting toxicity. Imatinib treatment induces a rapid 
response in newly diagnosed paediatric CML patients with a CHR of 78% after 8 weeks of therapy. The high 
rate of CHR is accompanied by the development of a complete cytogenetic response (CCyR) of 65% which 
is comparable to the results observed in adults. Additionally, partial cytogenetic response (PCyR) was 
observed in 16% for a MCyR of 81%. The majority of patients who achieved a CCyR developed the CCyR 
between months 3 and 10 with a median time to response based on the Kaplan-Meier estimate of 5.6 months. 
 
The European Medicines Agency has waived the obligation to submit the results of studies with imatinib in 
all subsets of the paediatric population in Philadelphia chromosome (bcr-abl translocation)-positive chronic 
myeloid leukaemia (see section 4.2 for information on paediatric use). 
 
Clinical studies in Ph+ ALL 
Newly diagnosed Ph+ ALL: In a controlled study (ADE10) of imatinib versus chemotherapy induction in 55 
newly diagnosed patients aged 55 years and over, imatinib used as single agent induced a significantly higher 
rate of complete haematological response than chemotherapy (96.3% vs. 50%; p=0.0001). When salvage 
therapy with imatinib was administered in patients who did not respond or who responded poorly to 
chemotherapy, it resulted in 9 patients (81.8%) out of 11 achieving a complete haematological response. This 
clinical effect was associated with a higher reduction in bcr-abl transcripts in the imatinib-treated patients 
than in the chemotherapy arm after 2 weeks of therapy (p=0.02). All patients received imatinib and 
consolidation chemotherapy (see Table 3) after induction and the levels of bcr-abl transcripts were identical 
in the two arms at 8 weeks. As expected on the basis of the study design, no difference was observed in 
remission duration, disease-free survival or overall survival, although patients with complete molecular 
response and remaining in minimal residual disease had a better outcome in terms of both remission duration 
(p=0.01) and disease-free survival (p=0.02). 
 
The results observed in a population of 211 newly diagnosed Ph+ ALL patients in four uncontrolled clinical 
studies (AAU02, ADE04, AJP01 and AUS01) are consistent with the results described above. Imatinib in 
combination with chemotherapy induction (see Table 3) resulted in a complete haematological response rate 
of 93% (147 out of 158 evaluable patients) and in a major cytogenetic response rate of 90% (19 out of 21 
evaluable patients). The complete molecular response rate was 48% (49 out of 102 evaluable patients). 
Disease-free survival (DFS) and overall survival (OS) constantly exceeded 1 year and were superior to 
historical control (DFS p<0.001; OS p<0.0001) in two studies (AJP01 and AUS01).

Paediatric patients: In study I2301, a total of 93 paediatric, adolescent and young adult patients (from 1 to 
22 years old) with Ph+ ALL were enrolled in an open-label, multicentre, sequential cohort, non-randomised 
phase III trial, and were treated with imatinib (340 mg/m2/day) in combination with intensive chemotherapy 
after induction therapy. Imatinib was administered intermittently in cohorts 1-5, with increasing duration and 
earlier start of imatinib from cohort to cohort; cohort 1 receiving the lowest intensitiy and cohort 5 receiving 
the highest intensity of imatinib (longest duration in days with continuous daily imatinib dosing during the 
first chemotherapy treatment courses). Continuous daily exposure to imatinib early in the course of treatment 
in combination with chemotherapy in cohort 5-patients (n=50) improved the 4-year event-free survival (EFS) 
compared to historical controls (n=120), who received standard chemotherapy without imatinib (69.6% vs. 
31.6%, respectively). The estimated 4-year OS in cohort 5-patients was 83.6% compared to 44.8% in the 
historical controls. 20 out of the 50 (40%) patients in cohort 5 received haematopoietic stem cell transplant.

Study AIT07 was a multicentre, open-label, randomised, phase II/III study that included 128 patients (1 to < 
18 years) treated with imatinib in combination with chemotherapy. Safety data from this study seem to be in 
line with the safety profile of imatinib in Ph+ ALL patients. 
 
Relapsed/refractory Ph+ ALL: When imatinib was used as single agent in patients with relapsed/refractory 
Ph+ ALL, it resulted, in the 53 out of 411 patients evaluable for response, in a haematological response rate 
of 30% (9% complete) and a major cytogenetic response rate of 23%. (Of note, out of the 411 patients, 353 
were treated in an expanded access program without primary response data collected.) The median time to

progression in the overall population of 411 patients with relapsed/refractory Ph+ ALL ranged from 2.6 to 
3.1 months, and median overall survival in the 401 evaluable patients ranged from 4.9 to 9 months. The data 
was similar when re-analysed to include only those patients age 55 or older. 
 
Clinical studies in MDS/MPD 
Experience with imatinib in this indication is very limited and is based on haematological and cytogenetic 
response rates. There are no controlled trials demonstrating a clinical benefit or increased survival. One open 
label, multicentre, phase II clinical trial (study B2225) was conducted testing imatinib in diverse populations 
of patients suffering from life-threatening diseases associated with Abl, Kit or PDGFR protein tyrosine 
kinases. This study included 7 patients with MDS/MPD who were treated with imatinib 400 mg daily. Three 
patients presented a complete haematological response (CHR) and one patient experienced a partial 
haematological response (PHR). At the time of the original analysis, three of the four patients with detected 
PDGFR gene rearrangements developed haematological response (2 CHR and 1 PHR). The age of these 
patients ranged from 20 to 72 years. 
 
An observational registry (study L2401) was conducted to collect long-term safety and efficacy data in 
patients suffering from myeloproliferative neoplasms with PDGFR- β rearrangement and who were treated 
with imatinib. The 23 patients enrolled in this registry received imatinib at a median daily dose of 264 mg 
(range: 100 to 400 mg) for a median duration of 7.2 years (range 0.1 to 12.7 years). Due to the observational 
nature of this registry, haematologic, cytogenetic and molecular assessment data were available for 22, 9 and 
17 of the 23 enrolled patients, respectively. When assuming conservatively that patients with missing data 
were non-responders, CHR was observed in 20/23 (87%) patients, CCyR in 9/23 (39.1%) patients, and MR 
in 11/23 (47.8%) patients, respectively. When the response rate is calculated from patients with at least one 
valid assessment, the response rate for CHR, CCyR and MR was 20/22 (90.9%), 9/9 (100%) and 11/17 
(64.7%), respectively. 
 
In addition a further 24 patients with MDS/MPD were reported in 13 publications. 21 patients were treated 
with imatinib 400 mg daily, while the other 3 patients received lower doses. In eleven patients PDGFR gene 
rearrangements was detected, 9 of them achieved a CHR and 1 PHR. The age of these patients ranged from 2 
to 79 years. In a recent publication updated information from 6 of these 11 patients revealed that all these 
patients remained in cytogenetic remission (range 32-38 months). The same publication reported long term 
follow-up data from 12 MDS/MPD patients with PDGFR gene rearrangements (5 patients from study 
B2225). These patients received imatinib for a median of 47 months (range 24 days – 60 months). In 6 of 
these patients follow-up now exceeds 4 years. Eleven patients achieved rapid CHR; ten had complete 
resolution of cytogenetic abnormalities and a decrease or disappearance of fusion transcripts as measured by 
RT-PCR. Haematological and cytogenetic responses have been sustained for a median of 49 months (range 
19-60) and 47 months (range 16-59), respectively. The overall survival is 65 months since diagnosis (range 
25-234). Imatinib administration to patients without the genetic translocation generally results in no 
improvement. 
 
There are no controlled trials in paediatric patients with MDS/MPD. Five (5) patients with MDS/MPD 
associated with PDGFR gene re-arrangements were reported in 4 publications. The age of these patients 
ranged from 3 months to 4 years and imatinib was given at dose 50 mg daily or doses ranging from 92.5 to 
340 mg/m2 daily. All patients achieved complete haematological response, cytogenetic response and/or 
clinical response. 
 
Clinical studies in HES/CEL 
One open-label, multicentre, phase II clinical trial (study B2225) was conducted testing imatinib in diverse 
populations of patients suffering from life-threatening diseases associated with Abl, Kit or PDGFR protein 
tyrosine kinases. In this study, 14 patients with HES/CEL were treated with 100 mg to 1,000 mg of imatinib 
daily. A further 162 patients with HES/CEL, reported in 35 published case reports and case series received 
imatinib at doses from 75 mg to 800 mg daily. Cytogenetic abnormalities were evaluated in 117 of the total 
population of 176 patients. In 61 of these 117 patients FIP1L1-PDGFRα fusion kinase was identified. An 
additional four HES patients were found to be FIP1L1-PDGFRα-positive in other 3 published reports. All 65 
FIP1L1-PDGFRα fusion kinase positive patients achieved a CHR sustained for months (range from 1+ to

44+ months censored at the time of the reporting). As reported in a recent publication 21 of these 65 patients 
also achieved complete molecular remission with a median follow-up of 28 months (range 13-67 months). 
The age of these patients ranged from 25 to 72 years. Additionally, improvements in symptomatology and 
other organ dysfunction abnormalities were reported by the investigators in the case reports. Improvements 
were reported in cardiac, nervous, skin/subcutaneous tissue, respiratory/thoracic/mediastinal, 
musculoskeletal/connective tissue/vascular, and gastrointestinal organ systems. 
 
There are no controlled trials in paediatric patients with HES/CEL. Three (3) patients with HES and CEL 
associated with PDGFR gene re-arrangements were reported in 3 publications. The age of these patients 
ranged from 2 to 16 years and imatinib was given at dose 300 mg/m2 daily or doses ranging from 200 to 400 
mg daily. All patients achieved complete haematological response, complete cytogenetic response and/or 
complete molecular response. 
 
Clinical studies in unresectable and/or metastatic GIST 
One phase II, open-label, randomised, uncontrolled multinational study was conducted in patients with 
unresectable or metastatic malignant gastrointestinal stromal tumours (GIST). In this study 147 patients were 
enrolled and randomised to receive either 400 mg or 600 mg orally once daily for up to 36 months. These 
patients ranged in age from 18 to 83 years old and had a pathologic diagnosis of Kit-positive malignant GIST 
that was unresectable and/or metastatic. Immunohistochemistry was routinely performed with Kit antibody 
(A-4502, rabbit polyclonal antiserum, 1:100; DAKO Corporation, Carpinteria, CA) according to analysis by 
an avidin-biotin-peroxidase complex method after antigen retrieval. 
 
The primary evidence of efficacy was based on objective response rates. Tumours were required to be 
measurable in at least one site of disease, and response characterisation based on Southwestern Oncology 
Group (SWOG) criteria. Results are provided in Table 5.

There were no differences in response rates between the two dose groups. A significant number of patients 
who had stable disease at the time of the interim analysis achieved a partial response with longer treatment 
(median follow-up 31 months). Median time to response was 13 weeks (95% C.I. 12–23). Median time to 
treatment failure in responders was 122 weeks (95% C.I 106–147), while in the overall study population it 
was 84 weeks (95% C.I 71–109). The median overall survival has not been reached. The Kaplan-Meier 
estimate for survival after 36-month follow-up is 68%. 
 
In two clinical studies (study B2222 and an intergroup study S0033) the daily dose of imatinib was escalated 
to 800 mg in patients progressing at the lower daily doses of 400 mg or 600 mg. The daily dose was 
escalated to 800 mg in a total of 103 patients; 6 patients achieved a partial response and 21 stabilisation of 
their disease after dose escalation for an overall clinical benefit of 26%. From the safety data available, 
escalating the dose to 800 mg daily in patients progressing at lower doses of 400 mg or 600 mg daily does 
not seem to affect the safety profile of imatinib.

In the adjuvant setting, imatinib was investigated in a multicentre, double-blind, long-term, placebo-
controlled phase III study (Z9001) involving 773 patients. The ages of these patients ranged from 18 to 91 
years. Patients were included who had a histological diagnosis of primary GIST expressing Kit protein by 
immunochemistry and a tumour size ≥ 3 cm in maximum dimension, with complete gross resection of 
primary GIST within 14-70 days prior to registration. After resection of primary GIST, patients were 
randomised to one of the two arms: imatinib at 400 mg/day or matching placebo for one year. 
 
The primary endpoint of the study was recurrence-free survival (RFS), defined as the time from date of 
randomisation to the date of recurrence or death from any cause. 
 
Imatinib significantly prolonged RFS, with 75% of patients being recurrence-free at 38 months in the 
imatinib group vs. 20 months in the placebo group (95% CIs, [30 - non-estimable]; [14 - non- estimable], 
respectively); (hazard ratio = 0.398 [0.259-0.610], p<0.0001). At one year the overall RFS was significantly 
better for imatinib (97.7%) vs. placebo (82.3%), (p<0.0001). The risk of recurrence was thus reduced by 
approximately 89% as compared with placebo (hazard ratio = 0.113 [0.049-0.264]). 
 
The risk of recurrence in patients after surgery of their primary GIST was retrospectively assessed based on 
the following prognostic factors: tumour size, mitotic index, tumour location. Mitotic index data were 
available for 556 of the 713 intention-to-treat (ITT) population. The results of subgroup analyses according 
to the United States National Institutes of Health (NIH) and the Armed Forces Institute of Pathology (AFIP) 
risk classifications are shown in Table 6. No benefit was observed in the low and very low risk groups. No 
overall survival benefit has been observed.

the peritoneal cavity. There were a total of 397 patients consented and randomised to the study (199 patients 
on 12-month arm and 198 patients on 36-month arm), median age was 61 years (range 22 to 84 years). The 
median time of follow-up was 54 months (from date of randomisation to data cut-off), with a total of 83 
months between the first patient randomised and the cut-off date. 
 
The primary endpoint of the study was recurrence-free survival (RFS), defined as the time from 
date of randomisation to the date of recurrence or death from any cause. 
 
Thirty-six (36) months of imatinib treatment significantly prolonged RFS compared to 12 months of imatinib 
treatment (with overall Hazard Ratio (HR) = 0.46 [0.32, 0.65], p<0.0001) (Table 7, Figure 1). 
 
In addition, thirty-six (36) months of imatinib treatment significantly prolonged overall survival (OS) 
compared to 12 months of imatinib treatment (HR = 0.45 [0.22, 0.89], p=0.0187) (Table 7, Figure 2).

Longer duration of the treatment (> 36 months) may delay the onset of further recurrences; 
however the impact of this finding on the overall survival remains unknown. 
 
The total number of deaths were 25 for the 12-month treatment arm and 12 for the 36-month 
treatment arm.  
 
Treatment with imatinib for 36 months was superior to treatment for 12 months in the ITT 
analysis, i.e. including the entire study population. In a planned subgroup analysis by mutation 
type, the HR for RFS for 36 months of treatment for patients with mutations of exon 11 was 0.35 
[95% CI: 0.22, 0.56]. No conclusions can be drawn for other less common mutation subgroups due 
to the low number of observed events.

There are no controlled trials in paediatric patients with c-Kit positive GIST. Seventeen (17) patients with 
GIST (with or without Kit and PDGFR mutations) were reported in 7 publications. The age of these patients 
ranged from 8 to 18 years and imatinib was given in both adjuvant and metastatic settings at doses ranging 
from 300 to 800 mg daily. The majority of paediatric patients treated for GIST lacked data confirming c-kit 
or PDGFR mutations which may have led to mixed clinical outcomes. 
 
Clinical studies in DFSP 
One phase II, open label, multicentre clinical trial (study B2225) was conducted including 12 patients with 
DFSP treated with imatinib 800 mg daily. The age of the DFSP patients ranged from 23 to 75 years; DFSP 
was metastatic, locally recurrent following initial resective surgery and not considered amenable to further 
resective surgery at the time of study entry. The primary evidence of efficacy was based on objective 
response rates. Out of the 12 patients enrolled, 9 responded, one completely and 8 partially. Three of the 
partial responders were subsequently rendered disease free by surgery. The median duration of therapy in 
study B2225 was 6.2 months, with a maximum duration of 24.3 months. A further 6 DFSP patients treated 
with imatinib were reported in 5 published case reports, their ages ranging from 18 months to 49 years. The 
adult patients reported in the published literature were treated with either 400 mg (4 cases) or 800 mg (1 
case) imatinib daily. Five (5) patients responded, 3 completely and 2 partially. The median duration of 
therapy in the published literature ranged between 4 weeks and more than 20 months. The translocation 
t(17:22)[(q22:q13)], or its gene product, was present in nearly all responders to imatinib treatment. 
 
There are no controlled trials in paediatric patients with DFSP. Five (5) patients with DFSP and PDGFR 
gene re-arrangements were reported in 3 publications. The age of these patients ranged from newborn to 14 
years and imatinib was given at dose 50 mg daily or doses ranging from 400 to 520 mg/m2 daily. All patients 
achieved partial and/or complete response. 
 
5.2 Pharmacokinetic properties 
 
Pharmacokinetics of imatinib 
The pharmacokinetics of imatinib have been evaluated over a dosage range of 25 to 1,000 mg. Plasma 
pharmacokinetic profiles were analysed on day 1 and on either day 7 or day 28, by which time plasma 
concentrations had reached steady state. 
 
Absorption 
Mean absolute bioavailability for imatinib is 98%. There was high between-patient variability in plasma 
imatinib AUC levels after an oral dose. When given with a high-fat meal, the rate of absorption of imatinib 
was minimally reduced (11% decrease in Cmax and prolongation of tmax by 1.5 h), with a small reduction in 

Me

ng

er
 au

th
or

ise
d



26 
 

AUC (7.4%) compared to fasting conditions. The effect of prior gastrointestinal surgery on drug absorption 
has not been investigated. 
 
Distribution 
At clinically relevant concentrations of imatinib, binding to plasma proteins was approximately 95% on the 
basis of in vitro experiments, mostly to albumin and alpha-acid-glycoprotein, with little binding to 
lipoprotein. 
 
Biotransformation 
The main circulating metabolite in humans is the N-demethylated piperazine derivative, which shows similar 
in vitro potency to the parent. The plasma AUC for this metabolite was found to be only 16% of the AUC for 
imatinib. The plasma protein binding of the N-demethylated metabolite is similar to that of the parent 
compound. 
 
Imatinib and the N-demethyl metabolite together accounted for about 65% of the circulating radioactivity 
(AUC(0-48h)). The remaining circulating radioactivity consisted of a number of minor metabolites. 
 
The in vitro results showed that CYP3A4 was the major human P450 enzyme catalysing the 
biotransformation of imatinib. Of a panel of potential comedications (acetaminophen, aciclovir, allopurinol, 
amphotericin, cytarabine, erythromycin, fluconazole, hydroxyurea, norfloxacin, penicillin V) only 
erythromycin (IC50 50 μM) and fluconazole (IC50 118 μM) showed inhibition of imatinib metabolism which 
could have clinical relevance. 
 
Imatinib was shown in vitro to be a competitive inhibitor of marker substrates for CYP2C9, CYP2D6 and 
CYP3A4/5. Ki values in human liver microsomes were 27, 7.5 and 7.9 µmol/l, respectively. Maximal plasma 
concentrations of imatinib in patients are 2-4 µmol/l, consequently an inhibition of CYP2D6 and/or 
CYP3A4/5-mediated metabolism of co-administered drugs is possible. Imatinib did not interfere with the 
biotransformation of 5-fluorouracil, but it inhibited paclitaxel metabolism as a result of competitive 
inhibition of CYP2C8 (Ki = 34.7 μM). This K i value is far higher than the expected plasma levels of imatinib 
in patients; consequently no interaction is expected upon co-administration of either 5-fluorouracil or 
paclitaxel and imatinib. 
 
Elimination 
Based on the recovery of compound(s) after an oral 14C-labelled dose of imatinib, approximately 81% of the 
dose was recovered within 7 days in faeces (68% of dose) and urine (13% of dose). Unchanged imatinib 
accounted for 25% of the dose (5% urine, 20% faeces), the remainder being metabolites. 
 
Plasma pharmacokinetics 
Following oral administration in healthy volunteers, the t½ was approximately 18 h, suggesting that once-
daily dosing is appropriate. The increase in mean AUC with increasing dose was linear and dose proportional 
in the range of 25-1,000 mg imatinib after oral administration. There was no change in the kinetics of 
imatinib on repeated dosing, and accumulation was 1.5-2.5-fold at steady state when dosed once daily. 
 
Pharmacokinetics in GIST patients 
In patients with GIST steady-state exposure was 1.5-fold higher than that observed for CML patients for the 
same dosage (400 mg daily). Based on preliminary population pharmacokinetic analysis in GIST patients, 
there were three variables (albumin, WBC and bilirubin) found to have a statistically significant relationship 
with imatinib pharmacokinetics. Decreased values of albumin caused a reduced clearance (CL/f); and higher 
levels of WBC led to a reduction of CL/f. However, these associations are not sufficiently pronounced to 
warrant dose adjustment. In this patient population, the presence of hepatic metastases could potentially lead 
to hepatic insufficiency and reduced metabolism. 
 
Population pharmacokinetics 
Based on population pharmacokinetic analysis in CML patients, there was a small effect of age on the 
volume of distribution (12% increase in patients > 65 years old). This change is not thought to be clinically 

Me

significant. The effect of bodyweight on the clearance of imatinib is such that for a patient weighing 50 kg 
the mean clearance is expected to be 8.5 l/h, while for a patient weighing 100 kg the clearance will rise to 
11.8 l/h. These changes are not considered sufficient to warrant dose adjustment based on kg bodyweight. 
There is no effect of gender on the kinetics of imatinib. 
 
Pharmacokinetics in children 
As in adult patients, imatinib was rapidly absorbed after oral administration in paediatric patients in both 
phase I and phase II studies. Dosing in children at 260 and 340 mg/m2/day achieved the same exposure, 
respectively, as doses of 400 mg and 600 mg in adult patients. The comparison of AUC(0-24) on day 8 and day 
1 at the 340 mg/m2/day dose level revealed a 1.7-fold drug accumulation after repeated once-daily dosing. 
 
Based on pooled population pharmacokinetic analysis in paediatric patients with haematological disorders 
(CML, Ph+ALL, or other haematological disorders treated with imatinib), clearance of imatinib increases 
with increasing body surface area (BSA). After correcting for the BSA effect, other demographics such as 
age, body weight and body mass index did not have clinically significant effects on the exposure of imatinib. 
The analysis confirmed that exposure of imatinib in paediatric patients receiving 260 mg/m2 once daily (not 
exceeding 400 mg once daily) or 340 mg/m2 once daily (not exceeding 600 mg once daily) were similar to 
those in adult patients who received imatinib 400 mg or 600 mg once daily. 
 
Organ function impairment 
Imatinib and its metabolites are not excreted via the kidney to a significant extent. Patients with mild and 
moderate impairment of renal function appear to have a higher plasma exposure than patients with normal 
renal function. The increase is approximately 1.5- to 2-fold, corresponding to a 1.5-fold elevation of plasma 
AGP, to which imatinib binds strongly. The free drug clearance of imatinib is probably similar between 
patients with renal impairment and those with normal renal function, since renal excretion represents only a 
minor elimination pathway for imatinib (see sections 4.2 and 4.4).  
 
Although the results of pharmacokinetic analysis showed that there is considerable inter-subject variation, 
the mean exposure to imatinib did not increase in patients with varying degrees of liver dysfunction as 
compared to patients with normal liver function (see sections 4.2, 4.4 and 4.8). 
 
5.3 Preclinical safety data 
 
The preclinical safety profile of imatinib was assessed in rats, dogs, monkeys and rabbits. 
 
Multiple dose toxicity studies revealed mild to moderate haematological changes in rats, dogs and monkeys, 
accompanied by bone marrow changes in rats and dogs. 
 
The liver was a target organ in rats and dogs. Mild to moderate increases in transaminases and slight 
decreases in cholesterol, triglycerides, total protein and albumin levels were observed in both species. No 
histopathological changes were seen in rat liver. Severe liver toxicity was observed in dogs treated for 2 
weeks, with elevated liver enzymes, hepatocellular necrosis, bile duct necrosis, and bile duct hyperplasia. 
 
Renal toxicity was observed in monkeys treated for 2 weeks, with focal mineralisation and dilation of the 
renal tubules and tubular nephrosis. Increased blood urea nitrogen (BUN) and creatinine were observed in 
several of these animals. In rats, hyperplasia of the transitional epithelium in the renal papilla and in the 
urinary bladder was observed at doses ≥ 6 mg/kg in the 13-week study, without changes in serum or urinary 
parameters. An increased rate of opportunistic infections was observed with chronic imatinib treatment. 
 
In a 39-week monkey study, no NOAEL (no observed adverse effect level) was established at the lowest 
dose of 15 mg/kg, approximately one-third the maximum human dose of 800 mg based on body surface. 
Treatment resulted in worsening of normally suppressed malarial infections in these animals. 
 
Imatinib was not considered genotoxic when tested in an in vitro bacterial cell assay (Ames test), an in vitro 
mammalian cell assay (mouse lymphoma) and an in vivo rat micronucleus test. Positive genotoxic effects

were obtained for imatinib in an in vitro mammalian cell assay (Chinese hamster ovary) for clastogenicity 
(chromosome aberration) in the presence of metabolic activation. Two intermediates of the manufacturing 
process, which are also present in the final product, are positive for mutagenesis in the Ames assay. One of 
these intermediates was also positive in the mouse lymphoma assay. 
 
In a study of fertility, in male rats dosed for 70 days prior to mating, testicular and epididymal weights and 
percent motile sperm were decreased at 60 mg/kg, approximately equal to the maximum clinical dose of 800 
mg/day, based on body surface area. This was not seen at doses ≤ 20 mg/kg. A slight to moderate reduction 
in spermatogenesis was also observed in the dog at oral doses ≥ 30 mg/kg. When female rats were dosed 14 
days prior to mating and through to gestational day 6, there was no effect on mating or on number of 
pregnant females. At a dose of 60 mg/kg, female rats had significant post-implantation foetal loss and a 
reduced number of live foetuses. This was not seen at doses ≤ 20 mg/kg. 
 
In an oral pre- and postnatal development study in rats, red vaginal discharge was noted in the 45 mg/kg/day 
group on either day 14 or day 15 of gestation. At the same dose, the number of stillborn pups as well as those 
dying between postpartum days 0 and 4 was increased. In the F1 offspring, at the same dose level, mean 
body weights were reduced from birth until terminal sacrifice and the number of litters achieving criterion 
for preputial separation was slightly decreased. F1 fertility was not affected, while an increased number of 
resorptions and a decreased number of viable foetuses was noted at 45 mg/kg/day. The no observed effect 
level (NOEL) for both the maternal animals and the F1 generation was 15 mg/kg/day (one quarter of the 
maximum human dose of 800 mg). 
 
Imatinib was teratogenic in rats when administered during organogenesis at doses ≥ 100 mg/kg, 
approximately equal to the maximum clinical dose of 800 mg/day, based on body surface area. Teratogenic 
effects included exencephaly or encephalocele, absent/reduced frontal and absent parietal bones. These 
effects were not seen at doses ≤ 30 mg/kg. 
 
No new target organs were identified in the rat juvenile development toxicology study (day 10 to 70 
postpartum) with respect to the known target organs in adult rats. In the juvenile toxicology study, effects 
upon growth, delay in vaginal opening and preputial separation were observed at approximately 0.3 to 2 
times the average paediatric exposure at the highest recommended dose of 340 mg/m2. In addition, mortality 
was observed in juvenile animals (around weaning phase) at approximately 2 times the average paediatric 
exposure at the highest recommended dose of 340 mg/m2. 
 
In the 2-year rat carcinogenicity study administration of imatinib at 15, 30 and 60 mg/kg/day resulted in a 
statistically significant reduction in the longevity of males at 60 mg/kg/day and females at ≥30 mg/kg/day. 
Histopathological examination of decedents revealed cardiomyopathy (both sexes), chronic progressive 
nephropathy (females) and preputial gland papilloma as principal causes of death or reasons for sacrifice. 
Target organs for neoplastic changes were the kidneys, urinary bladder, urethra, preputial and clitoral gland, 
small intestine, parathyroid glands, adrenal glands and non-glandular stomach. 
 
Papilloma/carcinoma of the preputial/clitoral gland were noted from 30 mg/kg/day onwards, representing 
approximately 0.5 or 0.3 times the human daily exposure (based on AUC) at 400 mg/day or 800 mg/day, 
respectively, and 0.4 times the daily exposure in children (based on AUC) at 340 mg/m2/day. The no 
observed effect level (NOEL) was 15 mg/kg/day. The renal adenoma/carcinoma, the urinary bladder and 
urethra papilloma, the small intestine adenocarcinomas, the parathyroid glands adenomas, the benign and 
malignant medullary tumours of the adrenal glands and the non-glandular stomach papillomas/carcinomas 
were noted at 60 mg/kg/day, representing approximately 1.7 or 1 times the human daily exposure (based on 
AUC) at 400 mg/day or 800 mg/day, respectively, and 1.2 times the daily exposure in children (based on 
AUC) at 340 mg/m2/day. The no observed effect level (NOEL) was 30 mg/kg/day. 
 
The mechanism and relevance of these findings in the rat carcinogenicity study for humans are not yet 
clarified.

Non-neoplastic lesions not identified in earlier preclinical studies were the cardiovascular system, pancreas, 
endocrine organs and teeth. The most important changes included cardiac hypertrophy and dilatation, leading 
to signs of cardiac insufficiency in some animals.

4. CLINICAL PARTICULARS 
 
4.1 Therapeutic indications 
 
Imatinib Teva B.V. is indicated for the treatment of  
• Paediatric patients with newly diagnosed Philadelphia chromosome (bcr-abl) positive (Ph+) chronic 

myeloid leukaemia (CML) for whom bone marrow transplantation is not considered as the first line of 
treatment.  

• Paediatric patients with Ph+ CML in chronic phase after failure of interferon-alpha therapy, or in 
accelerated phase or blast crisis. 

• Adult patients with Ph+ CML in blast crisis. 
• Adult and paediatric patients with newly diagnosed Philadelphia chromosome positive acute 

lymphoblastic leukaemia (Ph+ ALL) integrated with chemotherapy.  
• Adult patients with relapsed or refractory Ph+ ALL as monotherapy. 
• Adult patients with myelodysplastic/myeloproliferative diseases (MDS/MPD) associated with platelet-

derived growth factor receptor (PDGFR) gene re-arrangements. 
• Adult patients with advanced hypereosinophilic syndrome (HES) and/or chronic eosinophilic 

leukaemia (CEL) with FIP1L1-PDGFRα rearrangement. 
 
The effect of imatinib on the outcome of bone marrow transplantation has not been determined.

• The treatment of adult patients with Kit (CD 117) positive unresectable and/or metastatic malignant 
gastrointestinal stromal tumours (GIST). 

• The adjuvant treatment of adult patients who are at significant risk of relapse following resection of 
Kit (CD117)-positive GIST. Patients who have a low or very low risk of recurrence should not receive 
adjuvant treatment. 

• The treatment of adult patients with unresectable dermatofibrosarcoma protuberans (DFSP) and adult 
patients with recurrent and/or metastatic DFSP who are not eligible for surgery. 
 

In adult and paediatric patients, the effectiveness of imatinib is based on overall haematological and 
cytogenetic response rates and progression-free survival in CML, on haematological and cytogenetic 
response rates in Ph+ ALL, MDS/MPD, on haematological response rates in HES/CEL and on objective 
response rates in adult patients with unresectable and/or metastatic GIST and DFSP and on recurrence-free 
survival in adjuvant GIST. The experience with imatinib in patients with MDS/MPD associated with PDGFR 
gene re-arrangements is very limited (see section 5.1). There are no controlled trials demonstrating a clinical 
benefit or increased survival for these diseases.  
 
4.2 Posology and method of administration 
 
Therapy should be initiated by a physician experienced in the treatment of patients with haematological 
malignancies and malignant sarcomas, as appropriate. 
 
The prescribed dose should be administered orally with a meal and a large glass of water to minimise the risk 
of gastrointestinal irritations. Doses of 400 mg or 600 mg should be administered once daily, whereas a daily 
dose of 800 mg should be administered as 400 mg twice a day, in the morning and in the evening. For 
patients (children) unable to swallow the capsules, their content may be diluted in a glass of either still water 
or apple juice. Since studies in animals have shown reproductive toxicity, and the potential risk for the 
human foetus is unknown, women of child-bearing potential who open capsules should be advised to handle 
the contents with caution and avoid skin-eye contact or inhalation (see section 4.6). Hands should be washed 
immediately after handling open capsules.  
 
Posology for CML in adult patients  
The recommended dose of Imatinib Teva B.V. is 600 mg/day for adult patients in blast crisis. Blast crisis is 
defined as blasts ≥ 30% in blood or bone marrow or extramedullary disease other than hepatosplenomegaly.  
 
Treatment duration: In clinical trials, treatment with imatinib was continued until disease progression. The 
effect of stopping treatment after the achievement of a complete cytogenetic response has not been 
investigated.  
 
Dose increases from 600 mg to a maximum of 800 mg (given as 400 mg twice daily) in patients with blast 
crisis may be considered in the absence of severe adverse drug reaction and severe non-leukaemia-related 
neutropenia or thrombocytopenia in the following circumstances: disease progression (at any time); failure to 
achieve a satisfactory haematological response after at least 3 months of treatment; failure to achieve a 
cytogenetic response after 12 months of treatment; or loss of a previously achieved haematological and/or 
cytogenetic response. Patients should be monitored closely following dose escalation given the potential for 
an increased incidence of adverse reactions at higher dosages.  
 
Posology for CML in children 
Dosing for children should be on the basis of body surface area (mg/m2). The dose of 340 mg/m2 daily is 
recommended for children with chronic phase CML and advanced phase CML (not to exceed the total dose 
of 800 mg). Treatment can be given as a once daily dose or alternatively the daily dose may be split into two 
administrations – one in the morning and one in the evening. The dose recommendation is currently based on 
a small number of paediatric patients (see sections 5.1 and 5.2). 
There is no experience with the treatment of children below 2 years of age.  
 
Dose increases from 340 mg/m2 daily to 570 mg/m2 daily (not to exceed the total dose of 800 mg) may be 
considered in children in the absence of severe adverse drug reaction and severe non-leukaemia-related

neutropenia or thrombocytopenia in the following circumstances: disease progression (at any time); failure to 
achieve a satisfactory haematological response after at least 3 months of treatment; failure to achieve a 
cytogenetic response after 12 months of treatment; or loss of a previously achieved haematological and/or 
cytogenetic response. Patients should be monitored closely following dose escalation given the potential for 
an increased incidence of adverse reactions at higher dosages. 
 
Posology for Ph+ ALL in adult patients  
The recommended dose of Imatinib Teva B.V. is 600 mg/day for adult patients with Ph+ ALL. 
Haematological experts in the management of this disease should supervise the therapy throughout all phases 
of care.  
 
Treatment schedule: On the basis of the existing data, imatinib has been shown to be effective and safe when 
administered at 600 mg/day in combination with chemotherapy in the induction phase, the consolidation and 
maintenance phases of chemotherapy (see section 5.1) for adult patients with newly diagnosed Ph+ ALL. 
The duration of imatinib therapy can vary with the treatment programme selected, but generally longer 
exposures to imatinib have yielded better results.  
 
For adult patients with relapsed or refractory Ph+ALL imatinib monotherapy at 600 mg/day is safe, effective 
and can be given until disease progression occurs.  
 
Posology for Ph+ ALL in children 
Dosing for children should be on the basis of body surface area (mg/m2). The dose of 340 mg/m2 daily is 
recommended for children with Ph+ ALL (not to exceed the total dose of 600 mg).  
 
Posology for MDS/MPD  
The recommended dose of Imatinib Teva B.V. is 400 mg/day for adult patients with MDS/MPD.  
 
Treatment duration: In the only clinical trial performed up to now, treatment with imatinib was continued 
until disease progression (see section 5.1). At the time of analysis, the treatment duration was a median of 47 
months (24 days - 60 months).  
 
Posology for HES/CEL  
The recommended dose of Imatinib Teva B.V. is 100 mg/day for adult patients with HES/CEL.  
 
Dose increase from 100 mg to 400 mg may be considered in the absence of adverse drug reactions if 
assessments demonstrate an insufficient response to therapy.  
 
Treatment should be continued as long as the patient continues to benefit.  
 
Posology for GIST 
The recommended dose of Imatinib Teva B.V. is 400 mg/day for adult patients with unresectable and/or 
metastatic malignant GIST. 
 
Limited data exist on the effect of dose increases from 400 mg to 600 mg or 800 mg in patients progressing 
at the lower dose (see section 5.1). 
 
Treatment duration: In clinical trials in GIST patients, treatment with imatinib was continued until disease 
progression. At the time of analysis, the treatment duration was a median of 7 months (7 days to 13 months). 
The effect of stopping treatment after achieving a response has not been investigated. 
 
The recommended dose of Imatinib Teva B.V. is 400 mg/day for the adjuvant treatment of adult patients 
following resection of GIST. Optimal treatment duration is not yet established. Length of treatment in the 
clinical trial supporting this indication was 36 months (see section 5.1). 
 
Posology for DFSP  
The recommended dose of Imatinib Teva B.V. is 800 mg/day for adult patients with DFSP.

Dose adjustment for adverse reactions 
Non-haematological adverse reactions 
If a severe non-haematological adverse reaction develops with imatinib use, treatment must be withheld until 
the event has resolved. Thereafter, treatment can be resumed as appropriate depending on the initial severity 
of the event. 
 
If elevations in bilirubin > 3 x institutional upper limit of normal (IULN) or in liver transaminases > 5 x 
IULN occur, imatinib should be withheld until bilirubin levels have returned to < 1.5 x IULN and 
transaminase levels to < 2.5 x IULN. Treatment with imatinib may then be continued at a reduced daily dose. 
In adults the dose should be reduced from 400 to 300 mg or from 600 to 400 mg, or from 800 mg to 600 mg, 
and in children from 340 to 260 mg/m2/day. 
 
Haematological adverse reactions 
Dose reduction or treatment interruption for severe neutropenia and thrombocytopenia are recommended as 
indicated in the table below. 
 
Dose adjustments for neutropenia and thrombocytopenia:

Special populations  
Paediatric use: There is no experience in children with CML below 2 years of age and with Ph+ALL below 
1 year of age (see section 5.1). There is very limited experience in children with MDS/MPD, DFSP, GIST 
and HES/CEL. 
 
The safety and efficacy of imatinib in children with MDS/MPD, DFSP, GIST and HES/CEL aged less than 
18 years of age have not been established in clinical trials. Currently available published data are 
summarised in section 5.1 but no recommendation on a posology can be made. 
 
Hepatic insufficiency: Imatinib is mainly metabolised through the liver. Patients with mild, moderate or 
severe liver dysfunction should be given the minimum recommended dose of 400 mg daily. The dose can be 
reduced if not tolerated (see sections 4.4, 4.8 and 5.2). 
 
Liver dysfunction classification: 
 
Liver dysfunction Liver function tests 
Mild Total bilirubin: = 1.5 ULN 

AST: >ULN (can be normal or < ULN if total bilirubin is > ULN) 
Moderate Total bilirubin: > 1.5-3.0 ULN 

AST: any 
Severe Total bilirubin: > 3-10 ULN 

AST: any 
ULN = upper limit of normal for the institution 
AST = aspartate aminotransferase 
 
Renal insufficiency: Patients with renal dysfunction or on dialysis should be given the minimum 
recommended dose of 400 mg daily as starting dose. However, in these patients caution is recommended. 
The dose can be reduced if not tolerated. If tolerated, the dose can be increased for lack of efficacy (see 
sections 4.4 and 5.2). 
 
Older people: Imatinib pharmacokinetics have not been specifically studied in older people. No significant 
age-related pharmacokinetic differences have been observed in adult patients in clinical trials which included 
over 20% of patients age 65 and older. No specific dose recommendation is necessary in older people. 
 
4.3 Contraindications 
 
Hypersensitivity to the active substance or to any of the excipients listed in section 6.1. 
 
4.4 Special warnings and precautions for use 
 
When imatinib is co-administered with other medicinal products, there is a potential for drug interactions. 
Caution should be used when taking imatinib with protease inhibitors, azole antifungals, certain macrolides

(see section 4.5), CYP3A4 substrates with a narrow therapeutic window (e.g. cyclosporine, pimozide, 
tacrolimus, sirolimus, ergotamine, diergotamine, fentanyl, alfentanil, terfenadine, bortezomib, docetaxel, 
quinidine) or warfarin and other coumarin derivatives (see section 4.5). 
 
Concomitant use of imatinib and medicinal products that induce CYP3A4 (e.g. dexamethasone, phenytoin, 
carbamazepine, rifampicin, phenobarbital or Hypericum perforatum, also known as St. John’s Wort) may 
significantly reduce exposure to imatinib, potentially increasing the risk of therapeutic failure. Therefore, 
concomitant use of strong CYP3A4 inducers and imatinib should be avoided (see section 4.5). 
 
Hypothyroidism  
Clinical cases of hypothyroidism have been reported in thyroidectomy patients undergoing levothyroxine 
replacement during treatment with imatinib (see section 4.5). Thyroid-stimulating hormone (TSH) levels 
should be closely monitored in such patients. 
 
Hepatotoxicity  
Metabolism of imatinib is mainly hepatic, and only 13% of excretion is through the kidneys. In patients with 
hepatic dysfunction (mild, moderate or severe), peripheral blood counts and liver enzymes should be 
carefully monitored (see sections 4.2, 4.8 and 5.2). It should be noted that GIST patients may have hepatic 
metastases which could lead to hepatic impairment. 
 
Cases of liver injury, including hepatic failure and hepatic necrosis, have been observed with imatinib. When 
imatinib is combined with high dose chemotherapy regimens, an increase in serious hepatic reactions has 
been detected. Hepatic function should be carefully monitored in circumstances where imatinib is combined 
with chemotherapy regimens also known to be associated with hepatic dysfunction (see section 4.5 and 4.8). 
 
Fluid retention  
Occurrences of severe fluid retention (pleural effusion, oedema, pulmonary oedema, ascites, superficial 
oedema) have been reported in approximately 2.5% of newly diagnosed CML patients taking imatinib. 
Therefore, it is highly recommended that patients be weighed regularly. An unexpected rapid weight gain 
should be carefully investigated and if necessary appropriate supportive care and therapeutic measures 
should be undertaken. In clinical trials, there was an increased incidence of these events in older people and 
those with a prior history of cardiac disease. Therefore, caution should be exercised in patients with cardiac 
dysfunction. 
 
Patients with cardiac disease  
Patients with cardiac disease, risk factors for cardiac failure or history of renal failure should be monitored 
carefully, and any patient with signs or symptoms consistent with cardiac or renal failure should be evaluated 
and treated. 
 
In patients with hypereosinophilic syndrome (HES) with occult infiltration of HES cells within the 
myocardium, isolated cases of cardiogenic shock/left ventricular dysfunction have been associated with HES 
cell degranulation upon the initiation of imatinib therapy. The condition was reported to be reversible with 
the administration of systemic steroids, circulatory support measures and temporarily withholding imatinib. 
As cardiac adverse events have been reported uncommonly with imatinib, a careful assessment of the 
benefit/risk of imatinib therapy should be considered in the HES/CEL population before treatment initiation.  
 
Myelodysplastic/myeloproliferative diseases with PDGFR gene re-arrangements could be associated with 
high eosinophil levels. Evaluation by a cardiology specialist, performance of an echocardiogram and 
determination of serum troponin should therefore be considered in patients with HES/CEL, and in patients 
with MDS/MPD associated with high eosinophil levels before imatinib is administered. If either is abnormal, 
follow-up with a cardiology specialist and the prophylactic use of systemic steroids (1-2 mg/kg) for one to 
two weeks concomitantly with imatinib should be considered at the initiation of therapy. 
 
Gastrointestinal haemorrhage

37 
 

In the study in patients with unresectable and/or metastatic GIST, both gastrointestinal and intra-tumoural 
haemorrhages were reported (see section 4.8). Based on the available data, no predisposing factors (e.g. 
tumour size, tumour location, coagulation disorders) have been identified that place patients with GIST at a 
higher risk of either type of haemorrhage. Since increased vascularity and propensity for bleeding is a part of 
the nature and clinical course of GIST, standard practices and procedures for the monitoring and 
management of haemorrhage in all patients should be applied. 
 
In addition, gastric antral vascular ectasia (GAVE), a rare cause of gastrointestinal haemorrhage, has been 
reported in post-marketing experience in patients with CML, ALL and other diseases (see section 4.8). When 
needed, discontinuation of Imatinib Teva B.V. treatment may be considered. 
 
Tumour lysis syndrome  
Due to the possible occurrence of tumour lysis syndrome (TLS), correction of clinically significant 
dehydration and treatment of high uric acid levels are recommended prior to initiation of imatinib (see 
section 4.8). 
 
Hepatitis B reactivation  
Reactivation of hepatitis B in patients who are chronic carriers of this virus has occurred after these patients 
received BCR-ABL tyrosine kinase inhibitors. Some cases resulted in acute hepatic failure or fulminant 
hepatitis leading to liver transplantation or a fatal outcome. 
 
Patients should be tested for HBV infection before initiating treatment with Imatinib Teva B.V. Experts in 
liver disease and in the treatment of hepatitis B should be consulted before treatment is initiated in patients 
with positive hepatitis B serology (including those with active disease) and for patients who test positive for 
HBV infection during treatment. Carriers of HBV who require treatment with Imatinib Teva B.V. should be 
closely monitored for signs and symptoms of active HBV infection throughout therapy and for several 
months following termination of therapy (see section 4.8). 
 
Laboratory tests 
Complete blood counts must be performed regularly during therapy with imatinib. Treatment of CML 
patients with imatinib has been associated with neutropenia or thrombocytopenia. However, the occurrence 
of these cytopenias is likely to be related to the stage of the disease being treated and they were more 
frequent in patients with accelerated phase CML or blast crisis as compared to patients with chronic phase 
CML. Treatment with imatinib may be interrupted or the dose may be reduced, as recommended in section 
4.2. 
 
Liver function (transaminases, bilirubin, alkaline phosphatase) should be monitored regularly in patients 
receiving imatinib. 
 
In patients with impaired renal function, imatinib plasma exposure seems to be higher than that in patients 
with normal renal function, probably due to an elevated plasma level of alpha-acid glycoprotein (AGP), an 
imatinib-binding protein, in these patients. Patients with renal impairment should be given the minimum 
starting dose. Patients with severe renal impairment should be treated with caution. The dose can be reduced 
if not tolerated (see section 4.2 and 5.2). 
 
Long-term treatment with imatinib may be associated with a clinically significant decline in renal function. 
Renal function should, therefore, be evaluated prior to the start of imatinib therapy and closely monitored 
during therapy, with particular attention to those patients exhibiting risk factors for renal dysfunction. If renal 
dysfunction is observed, appropriate management and treatment should be prescribed in accordance with 
standard treatment guidelines. 
 
Paediatric population 
There have been case reports of growth retardation occurring in children and pre-adolescents receiving 
imatinib. The long-term effects of prolonged treatment with imatinib on growth in children are unknown.

Therefore, close monitoring of growth in children under imatinib treatment is recommended (see section 
4.8). 
 
4.5 Interaction with other medicinal products and other forms of interaction 
 
Active substances that may increase imatinib plasma concentrations 
Substances that inhibit the cytochrome P450 isoenzyme CYP3A4 activity (e.g. protease inhibitors such as 
indinavir, lopinavir/ritonavir, ritonavir, saquinavir, telaprevir, nelfinavir, boceprevir; azole antifungals 
including ketoconazole, itraconazole, posaconazole, voriconazole; certain macrolides such as erythromycin, 
clarithromycin and telithromycin) could decrease metabolism and increase imatinib concentrations. There 
was a significant increase in exposure to imatinib (the mean Cmax and AUC of imatinib rose by 26% and 
40%, respectively) in healthy subjects when it was co-administered with a single dose of ketoconazole (a 
CYP3A4 inhibitor). Caution should be taken when administering imatinib with inhibitors of the CYP3A4 
family. 
 
Active substances that may decrease imatinib plasma concentrations 
Substances that are inducers of CYP3A4 activity (e.g. dexamethasone, phenytoin, carbamazepine, 
rifampicin, phenobarbital, fosphenytoin, primidone or Hypericum perforatum, also known as St. John’s 
Wort) may significantly reduce exposure to imatinib, potentially increasing the risk of therapeutic failure. 
Pretreatment with multiple doses of rifampicin 600 mg followed by a single 400 mg dose of imatinib resulted 
in decrease in Cmax and AUC(0-∞) by at least 54% and 74%, of the respective values without rifampicin 
treatment. Similar results were observed in patients with malignant gliomas treated with imatinib while 
taking enzyme-inducing anti-epileptic drugs (EIAEDs) such as carbamazepine, oxcarbazepine and 
phenytoin. The plasma AUC for imatinib decreased by 73% compared to patients not on EIAEDs. 
Concomitant use of rifampicin or other strong CYP3A4 inducers and imatinib should be avoided. 
 
Active substances that may have their plasma concentration altered by imatinib 
Imatinib increases the mean Cmax and AUC of simvastatin (CYP3A4 substrate) 2- and 3.5-fold, respectively, 
indicating an inhibition of the CYP3A4 by imatinib. Therefore, caution is recommended when administering 
imatinib with CYP3A4 substrates with a narrow therapeutic window (e.g. cyclosporine, pimozide, 
tacrolimus, sirolimus, ergotamine, diergotamine, fentanyl, alfentanil, terfenadine, bortezomib, docetaxel and 
quinidine). Imatinib may increase plasma concentration of other CYP3A4 metabolised drugs (e.g. triazolo-
benzodiazepines, dihydropyridine calcium channel blockers, certain HMG-CoA reductase inhibitors, i.e. 
statins, etc.). 
 
Because of known increased risks of bleeding in conjunction with the use of imatinib (e.g. haemorrhage), 
patients who require anticoagulation should receive low-molecular-weight or standard heparin, instead of 
coumarin derivatives such as warfarin. 
 
In vitro imatinib inhibits the cytochrome P450 isoenzyme CYP2D6 activity at concentrations similar to those 
that affect CYP3A4 activity. Imatinib at 400 mg twice daily had an inhibitory effect on CYP2D6-mediated 
metoprolol metabolism, with metoprolol Cmax and AUC being increased by approximately 23% (90%CI 
[1.16-1.30]). Dose adjustments do not seem to be necessary when imatinib is co-administrated with CYP2D6 
substrates, however caution is advised for CYP2D6 substrates with a narrow therapeutic window such as 
metoprolol. In patients treated with metoprolol clinical monitoring should be considered. 
 
In vitro, imatinib inhibits paracetamol O-glucuronidation with Ki value of 58.5 micromol/l. This inhibition 
has not been observed in vivo after the administration of imatinib 400 mg and paracetamol 1000 mg. Higher 
doses of imatinib and paracetamol have not been studied. 
 
Caution should therefore be exercised when using high doses of imatinib and paracetamol concomitantly. 
 
In thyroidectomy patients receiving levothyroxine, the plasma exposure to levothyroxine may be decreased 
when imatinib is co-administered (see section 4.4). Caution is therefore recommended. However, the 
mechanism of the observed interaction is presently unknown.

In Ph+ ALL patients, there is clinical experience of co-administering imatinib with chemotherapy (see 
section 5.1), but drug-drug interactions between imatinib and chemotherapy regimens are not well 
characterised. Imatinib adverse events, i.e. hepatotoxicity, myelosuppression or others, may increase and it 
has been reported that concomitant use with L-asparaginase could be associated with increased 
hepatotoxicity (see section 4.8). Therefore, the use of imatinib in combination requires special precaution. 
 
4.6 Fertility, pregnancy and lactation 
 
Women of childbearing potential 
Women of childbearing potential must be advised to use effective contraception during treatment. 
 
Pregnancy 
There are limited data on the use of imatinib in pregnant women. There have been post-marketing reports of 
spontaneous abortions and infant congenital anomalies from women who have taken imatinib. Studies in 
animals have however shown reproductive toxicity (see section 5.3) and the potential risk for the foetus is 
unknown. Imatinib should not be used during pregnancy unless clearly necessary. If it is used during 
pregnancy, the patient must be informed of the potential risk to the foetus.  
 
Breast-feeding 
There is limited information on imatinib distribution on human milk. Studies in two breast-feeding women 
revealed that both imatinib and its active metabolite can be distributed into human milk. The milk plasma 
ratio studied in a single patient was determined to be 0.5 for imatinib and 0.9 for the metabolite, suggesting 
greater distribution of the metabolite into the milk. Considering the combined concentration of imatinib and 
the metabolite and the maximum daily milk intake by infants, the total exposure would be expected to be low 
(~10% of a therapeutic dose). However, since the effects of low-dose exposure of the infant to imatinib are 
unknown, women taking imatinib should not breast-feed. 
 
Fertility 
In non-clinical studies, the fertility of male and female rats was not affected (see section 5.3). Studies on 
patients receiving imatinib and its effect on fertility and gametogenesis have not been performed. Patients 
concerned about their fertility on imatinib treatment should consult with their physician. 
 
4.7 Effects on ability to drive and use machines 
 
Patients should be advised that they may experience undesirable effects such as dizziness, blurred vision or 
somnolence during treatment with imatinib. Therefore, caution should be recommended when driving a car 
or operating machinery. 
 
4.8 Undesirable effects 
 
Patients with advanced stages of malignancies may have numerous confounding medical conditions that 
make causality of adverse reactions difficult to assess due to the variety of symptoms related to the 
underlying disease, its progression, and the co-administration of numerous medicinal products. 
 
In clinical trials in CML, drug discontinuation for drug-related adverse reactions was observed in 2.4% of 
newly diagnosed patients, 4% of patients in late chronic phase after failure of interferon therapy, 4% of 
patients in accelerated phase after failure of interferon therapy and 5% of blast crisis patients after failure of 
interferon therapy. In GIST the study drug was discontinued for drug-related adverse reactions in 4% of 
patients. 
 
The adverse reactions were similar in all indications, with two exceptions. There was more 
myelosuppression seen in CML patients than in GIST, which is probably due to the underlying disease. In 
the study in patients with unresectable and/or metastatic GIST, 7 (5%) patients experienced CTC grade 3/4 
GI bleeds (3 patients), intra-tumoural bleeds (3 patients) or both (1 patient). GI tumour sites may have been 
the source of the GI bleeds (see section 4.4). GI and tumoural bleeding may be serious and sometimes fatal.

The most commonly reported (≥ 10%) drug-related adverse reactions in both settings were mild nausea, 
vomiting, diarrhoea, abdominal pain, fatigue, myalgia, muscle cramps and rash. Superficial oedemas were a 
common finding in all studies and were described primarily as periorbital or lower limb oedemas. However, 
these oedemas were rarely severe and may be managed with diuretics, other supportive measures, or by 
reducing the dose of imatinib. 
 
When imatinib was combined with high dose chemotherapy in Ph+ ALL patients, transient liver toxicity in 
the form of transaminase elevation and hyperbilirubinaemia were observed. Considering the limited safety 
database, the adverse events thus far reported in children are consistent with the known safety profile in adult 
patients with Ph+ ALL. The safety database for children with Ph+ALL is very limited though no new safety 
concerns have been identified. 
 
Miscellaneous adverse reactions such as pleural effusion, ascites, pulmonary oedema and rapid weight gain 
with or without superficial oedema may be collectively described as “fluid retention”. These reactions can 
usually be managed by withholding imatinib temporarily and with diuretics and other appropriate supportive 
care measures. However, some of these reactions may be serious or life-threatening and several patients with 
blast crisis died with a complex clinical history of pleural effusion, congestive heart failure and renal failure. 
There were no special safety findings in paediatric clinical trials. 
 
Adverse reactions 
Adverse reactions reported as more than an isolated case are listed below, by system organ class and by 
frequency. Frequency categories are defined using the following convention: very common (≥1/10), common 
(≥1/100 to <1/10), uncommon (≥1/1,000 to <1/100), rare (≥1/10,000 to <1/1,000), very rare (<1/10,000), not 
known (cannot be estimated from the available data). 
 
Within each frequency grouping, undesirable effects are presented in order of frequency, the most frequent 
first. 
 
Adverse reactions and their frequencies are reported in Table 1.

* These types of reactions have been reported mainly from post-marketing experience with imatinib. 

This includes spontaneous case reports as well as serious adverse events from ongoing studies, the 
expanded access programmes, clinical pharmacology studies and exploratory studies in unapproved 
indications. Because these reactions are reported from a population of uncertain size, it is not always 
possible to reliably estimate their frequency or establish a causal relationship to imatinib exposure. 

1  Pneumonia was reported most commonly in patients with transformed CML and in patients with 
GIST. 

2  Headache was the most common in GIST patients. 
3  On a patient-year basis, cardiac events including congestive heart failure were more commonly 

observed in patients with transformed CML than in patients with chronic CML. 
4  Flushing was most common in GIST patients and bleeding (haematoma, haemorrhage) was most 

common in patients with GIST and with transformed CML (CML-AP and CML-BC). 
5  Pleural effusion was reported more commonly in patients with GIST and in patients with transformed 

CML (CML-AP and CML-BC) than in patients with chronic CML.

8  Some fatal cases of hepatic failure and of hepatic necrosis have been reported. 
9. Musculoskeletal pain during treatment with imatinib or after discontinuation has been observed in 

post-marketing 
10  Musculoskeletal pain and related events were more commonly observed in patients with CML than in 

GIST patients. 
11 Fatal cases have been reported in patients with advanced disease, severe infections, severe neutropenia 

and other serious concomitant conditions. 
 
Laboratory test abnormalities  
Haematology  
In CML, cytopenias, particularly neutropenia and thrombocytopenia, have been a consistent finding in all 
studies, with the suggestion of a higher frequency at high doses ≥ 750 mg (phase I study). However, the 
occurrence of cytopenias was also clearly dependent on the stage of the disease, the frequency of grade 3 or 
4 neutropenias (ANC < 1.0 x 109/l) and thrombocytopenias (platelet count < 50 x 109/l) being between 4 and 
6 times higher in blast crisis and accelerated phase (59-64% and 44-63% for neutropenia and 
thrombocytopenia, respectively) as compared to newly diagnosed patients in chronic phase CML (16.7% 
neutropenia and 8.9% thrombocytopenia). In newly diagnosed chronic phase CML grade 4 neutropenia 
(ANC < 0.5 x 109/l) and thrombocytopenia (platelet count < 10 x 109/l) were observed in 3.6% and < 1% of 
patients, respectively. The median duration of the neutropenic and thrombocytopenic episodes usually 
ranged from 2 to 3 weeks, and from 3 to 4 weeks, respectively. These events can usually be managed with 
either a reduction of the dose or an interruption of treatment with imatinib, but can in rare cases lead to 
permanent discontinuation of treatment. In paediatric CML patients the most frequent toxicities observed 
were grade 3 or 4 cytopenias involving neutropenia, thrombocytopenia and anaemia. These generally occur 
within the first several months of therapy. 
 
In the study in patients with unresectable and/or metastatic GIST, grade 3 and 4 anaemia was reported in 
5.4% and 0.7% of patients, respectively, and may have been related to gastrointestinal or intra-tumoural 
bleeding in at least some of these patients. Grade 3 and 4 neutropenia was seen in 7.5% and 2.7% of patients, 
respectively, and grade 3 thrombocytopenia in 0.7% of patients. No patient developed grade 4 
thrombocytopenia. The decreases in white blood cell (WBC) and neutrophil counts occurred mainly during 
the first six weeks of therapy, with values remaining relatively stable thereafter. 
 
Biochemistry  
Severe elevation of transaminases (<5%) or bilirubin (<1%) was seen in CML patients and was usually 
managed with dose reduction or interruption (the median duration of these episodes was approximately one 
week). Treatment was discontinued permanently because of liver laboratory abnormalities in less than 1% of 
CML patients. In GIST patients (study B2222), 6.8% of grade 3 or 4 ALT (alanine aminotransferase) 
elevations and 4.8% of grade 3 or 4 AST (aspartate aminotransferase) elevations were observed. Bilirubin 
elevation was below 3%. 
 
There have been cases of cytolytic and cholestatic hepatitis and hepatic failure; in some of them outcome 
was fatal, including one patient on high dose paracetamol. 
 
Description of selected adverse reactions: 
Hepatitis B reactivation 
Hepatitis B reactivation has been reported in association with BCR-ABL TKIs. Some cases resulted in acute 
hepatic failure or fulminant hepatitis leading to liver transplantation or a fatal outcome (see section 4.4). 
 
Reporting of suspected adverse reactions 
Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allows 
continued monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals are asked 
to report any suspected adverse reactions via the national reporting system listed in Appendix V.

Experience with doses higher than the recommended therapeutic dose is limited. Isolated cases of imatinib 
overdose have been reported spontaneously and in the literature. In the event of overdose the patient should 
be observed and appropriate symptomatic treatment given. Generally the reported outcome in these cases 
was “improved” or “recovered”. Events that have been reported at different dose ranges are as follows: 
 
Adult population 
1200 to 1600 mg (duration varying between 1 to 10 days): Nausea, vomiting, diarrhoea, rash, erythema, 
oedema, swelling, fatigue, muscle spasms, thrombocytopenia, pancytopenia, abdominal pain, headache, 
decreased appetite.  
1800 to 3200 mg (as high as 3200 mg daily for 6 days): Weakness, myalgia, increased creatine 
phosphokinase, increased bilirubin, gastrointestinal pain.  
6400 mg (single dose): One case reported in the literature of one patient who experienced nausea, vomiting, 
abdominal pain, pyrexia, facial swelling, decreased neutrophil count, increased transaminases.  
8 to 10 g (single dose): Vomiting and gastrointestinal pain have been reported. 
 
Paediatric population 
One 3-year-old male exposed to a single dose of 400 mg experienced vomiting, diarrhoea and anorexia and 
another 3-year-old male exposed to a single dose of 980 mg experienced decreased white blood cell count 
and diarrhoea. 
 
In the event of overdose, the patient should be observed and appropriate supportive treatment given. 
 
 
5. PHARMACOLOGICAL PROPERTIES 
 
5.1 Pharmacodynamic properties 
 
Pharmacotherapeutic group: Protein kinase inhibitors, ATC code: L01XE01  
 
Mechanism of action 
Imatinib is a small molecule protein-tyrosine kinase inhibitor that potently inhibits the activity of the Bcr-Abl 
tyrosine kinase (TK), as well as several receptor TKs: Kit, the receptor for stem cell factor (SCF) coded for 
by the c-Kit proto-oncogene, the discoidin domain receptors (DDR1 and DDR2), the colony stimulating 
factor receptor (CSF-1R) and the platelet-derived growth factor receptors alpha and beta (PDGFR-alpha and 
PDGFR-beta). Imatinib can also inhibit cellular events mediated by activation of these receptor kinases. 
 
Pharmacodynamic effects 
Imatinib is a protein-tyrosine kinase inhibitor which potently inhibits the Bcr-Abl tyrosine kinase at the in 
vitro, cellular and in vivo levels. The compound selectively inhibits proliferation and induces apoptosis in 
Bcr-Abl positive cell lines as well as fresh leukaemic cells from Philadelphia chromosome positive CML and 
acute lymphoblastic leukaemia (ALL) patients. 
 
In vivo the compound shows anti-tumour activity as a single agent in animal models using Bcr-Abl positive 
tumour cells. 
 
Imatinib is also an inhibitor of the receptor tyrosine kinases for platelet-derived growth factor (PDGF), 
PDGF-R, and stem cell factor (SCF), c-Kit, and inhibits PDGF- and SCF-mediated cellular events. In vitro, 
imatinib inhibits proliferation and induces apoptosis in gastrointestinal stromal tumour (GIST) cells, which 
express an activating kit mutation. Constitutive activation of the PDGF receptor or the Abl protein tyrosine 
kinases as a consequence of fusion to diverse partner proteins or constitutive production of PDGF have been 
implicated in the pathogenesis of MDS/MPD, HES/CEL and DFSP. Imatinib inhibits signalling and 
proliferation of cells driven by dysregulated PDGFR and Abl kinase activity.

The effectiveness of imatinib is based on overall haematological and cytogenetic response rates and 
progression-free survival. There are no controlled trials demonstrating a clinical benefit, such as 
improvement in disease-related symptoms or increased survival. 
 
A large, international, open-label, non-controlled phase II study was conducted in patients with Philadelphia 
chromosome positive (Ph+) CML in the blast crisis phase of the disease. In addition, children have been 
treated in two phase I studies and one phase II study. 
 
In all clinical studies 38-40% of patients were ≥ 60 years of age and 10-12% of patients were ≥ 70 years of 
age. 
 
Myeloid blast crisis: 260 patients with myeloid blast crisis were enrolled. 95 (37%) had received prior 
chemotherapy for treatment of either accelerated phase or blast crisis (“pretreated patients”) whereas 165 
(63%) had not (“untreated patients”). The first 37 patients were started at 400 mg, the protocol was 
subsequently amended to allow higher dosing and the remaining 223 patients were started at 600 mg. 
 
The primary efficacy variable was the rate of haematological response, reported as either complete 
haematological response, no evidence of leukaemia (i.e. clearance of blasts from the marrow and the blood, 
but without a full peripheral blood recovery as for complete responses), or return to chronic phase CML. In 
this study, 31% of patients achieved a haematological response (36% in previously untreated patients and 
22% in previously treated patients). The rate of response was also higher in the patients treated at 600 mg 
(33%) as compared to the patients treated at 400 mg (16%, p=0.0220). The current estimate of the median 
survival of the previously untreated and treated patients was 7.7 and 4.7 months, respectively. 
 
Lymphoid blast crisis: a limited number of patients were enrolled in phase I studies (n=10). The rate of 
haematological response was 70% with a duration of 2-3 months.

Paediatric patients: A total of 26 paediatric patients of age < 18 years with either chronic phase CML (n=11) 
or CML in blast crisis or Ph+ acute leukaemias (n=15) were enrolled in a dose-escalation phase I trial. This 
was a population of heavily pretreated patients, as 46% had received prior BMT and 73% a prior multi-agent 
chemotherapy. Patients were treated at doses of imatinib of 260 mg/m2/day (n=5), 340 mg/m2/day (n=9), 440 
mg/m2/day (n=7) and 570 mg/m2/day (n=5). Out of 9 patients with chronic phase CML and cytogenetic data 
available, 4 (44%) and 3 (33%) achieved a complete and partial cytogenetic response, respectively, for a rate 
of MCyR of 77%. 
 
A total of 51 paediatric patients with newly diagnosed and untreated CML in chronic phase have been 
enrolled in an open-label, multicentre, single-arm phase II trial. Patients were treated with imatinib 340 
mg/m2/day, with no interruptions in the absence of dose limiting toxicity. Imatinib treatment induces a rapid 
response in newly diagnosed paediatric CML patients with a CHR of 78% after 8 weeks of therapy. The high 
rate of CHR is accompanied by the development of a complete cytogenetic response (CCyR) of 65% which 
is comparable to the results observed in adults. Additionally, partial cytogenetic response (PCyR) was 
observed in 16% for a MCyR of 81%. The majority of patients who achieved a CCyR developed the CCyR 
between months 3 and 10 with a median time to response based on the Kaplan-Meier estimate of 5.6 months. 
 
The European Medicines Agency has waived the obligation to submit the results of studies with imatinib in 
all subsets of the paediatric population in Philadelphia chromosome (bcr-abl translocation)-positive chronic 
myeloid leukaemia (see section 4.2 for information on paediatric use). 
 
Clinical studies in Ph+ ALL 
Newly diagnosed Ph+ ALL: In a controlled study (ADE10) of imatinib versus chemotherapy induction in 55 
newly diagnosed patients aged 55 years and over, imatinib used as single agent induced a significantly higher 
rate of complete haematological response than chemotherapy (96.3% vs. 50%; p=0.0001). When salvage 
therapy with imatinib was administered in patients who did not respond or who responded poorly to 
chemotherapy, it resulted in 9 patients (81.8%) out of 11 achieving a complete haematological response. This 
clinical effect was associated with a higher reduction in bcr-abl transcripts in the imatinib-treated patients 
than in the chemotherapy arm after 2 weeks of therapy (p=0.02). All patients received imatinib and 
consolidation chemotherapy (see Table 3) after induction and the levels of bcr-abl transcripts were identical 
in the two arms at 8 weeks. As expected on the basis of the study design, no difference was observed in 
remission duration, disease-free survival or overall survival, although patients with complete molecular 
response and remaining in minimal residual disease had a better outcome in terms of both remission duration 
(p=0.01) and disease-free survival (p=0.02). 
 
The results observed in a population of 211 newly diagnosed Ph+ ALL patients in four uncontrolled clinical 
studies (AAU02, ADE04, AJP01 and AUS01) are consistent with the results described above. Imatinib in 
combination with chemotherapy induction (see Table 3) resulted in a complete haematological response rate 
of 93% (147 out of 158 evaluable patients) and in a major cytogenetic response rate of 90% (19 out of 21 
evaluable patients). The complete molecular response rate was 48% (49 out of 102 evaluable patients). 
Disease-free survival (DFS) and overall survival (OS) constantly exceeded 1 year and were superior to 
historical control (DFS p<0.001; OS p<0.0001) in two studies (AJP01 and AUS01).

Paediatric patients: In study I2301, a total of 93 paediatric, adolescent and young adult patients (from 1 to 
22 years old) with Ph+ ALL were enrolled in an open-label, multicentre, sequential cohort, non-randomised 
phase III trial, and were treated with imatinib (340 mg/m2/day) in combination with intensive chemotherapy 
after induction therapy. Imatinib was administered intermittently in cohorts 1-5, with increasing duration and 
earlier start of imatinib from cohort to cohort; cohort 1 receiving the lowest intensitiy and cohort 5 receiving 
the highest intensity of imatinib (longest duration in days with continuous daily imatinib dosing during the 
first chemotherapy treatment courses). Continuous daily exposure to imatinib early in the course of treatment 
in combination with chemotherapy in cohort 5-patients (n=50) improved the 4-year event-free survival (EFS) 
compared to historical controls (n=120), who received standard chemotherapy without imatinib (69.6% vs. 
31.6%, respectively). The estimated 4-year OS in cohort 5-patients was 83.6% compared to 44.8% in the 
historical controls. 20 out of the 50 (40%) patients in cohort 5 received haematopoietic stem cell transplant.

Study AIT07 was a multicentre, open-label, randomised, phase II/III study that included 128 patients (1 to < 
18 years) treated with imatinib in combination with chemotherapy. Safety data from this study seem to be in 
line with the safety profile of imatinib in Ph+ ALL patients. 
 
Relapsed/refractory Ph+ ALL: When imatinib was used as single agent in patients with relapsed/refractory 
Ph+ ALL, it resulted, in the 53 out of 411 patients evaluable for response, in a haematological response rate 
of 30% (9% complete) and a major cytogenetic response rate of 23%. (Of note, out of the 411 patients, 353 
were treated in an expanded access program without primary response data collected.) The median time to 
progression in the overall population of 411 patients with relapsed/refractory Ph+ ALL ranged from 2.6 to 
3.1 months, and median overall survival in the 401 evaluable patients ranged from 4.9 to 9 months. The data 
was similar when re-analysed to include only those patients age 55 or older.  
 
Clinical studies in MDS/MPD 
Experience with imatinib in this indication is very limited and is based on haematological and cytogenetic 
response rates. There are no controlled trials demonstrating a clinical benefit or increased survival. One open 
label, multicentre, phase II clinical trial (study B2225) was conducted testing imatinib in diverse populations 
of patients suffering from life-threatening diseases associated with Abl, Kit or PDGFR protein tyrosine 
kinases. This study included 7 patients with MDS/MPD who were treated with imatinib 400 mg daily. Three 
patients presented a complete haematological response (CHR) and one patient experienced a partial 
haematological response (PHR). At the time of the original analysis, three of the four patients with detected

PDGFR gene rearrangements developed haematological response (2 CHR and 1 PHR). The age of these 
patients ranged from 20 to 72 years. 
 
An observational registry (study L2401) was conducted to collect long-term safety and efficacy data in 
patients suffering from myeloproliferative neoplasms with PDGFR- β rearrangement and who were treated 
with imatinib. The 23 patients enrolled in this registry received imatinib at a median daily dose of 264 mg 
(range: 100 to 400 mg) for a median duration of 7.2 years (range 0.1 to 12.7 years). Due to the observational 
nature of this registry, haematologic, cytogenetic and molecular assessment data were available for 22, 9 and 
17 of the 23 enrolled patients, respectively. When assuming conservatively that patients with missing data 
were non-responders, CHR was observed in 20/23 (87%) patients, CCyR in 9/23 (39.1%) patients, and MR 
in 11/23 (47.8%) patients, respectively. When the response rate is calculated from patients with at least one 
valid assessment, the response rate for CHR, CCyR and MR was 20/22 (90.9%), 9/9 (100%) and 11/17 
(64.7%), respectively. 
 
In addition a further 24 patients with MDS/MPD were reported in 13 publications. 21 patients were treated 
with imatinib 400 mg daily, while the other 3 patients received lower doses. In eleven patients PDGFR gene 
rearrangements was detected, 9 of them achieved a CHR and 1 PHR. The age of these patients ranged from 2 
to 79 years. In a recent publication updated information from 6 of these 11 patients revealed that all these 
patients remained in cytogenetic remission (range 32-38 months). The same publication reported long term 
follow-up data from 12 MDS/MPD patients with PDGFR gene rearrangements (5 patients from study 
B2225). These patients received imatinib for a median of 47 months (range 24 days – 60 months). In 6 of 
these patients follow-up now exceeds 4 years. Eleven patients achieved rapid CHR; ten had complete 
resolution of cytogenetic abnormalities and a decrease or disappearance of fusion transcripts as measured by 
RT-PCR. Haematological and cytogenetic responses have been sustained for a median of 49 months (range 
19-60) and 47 months (range 16-59), respectively. The overall survival is 65 months since diagnosis (range 
25-234). Imatinib administration to patients without the genetic translocation generally results in no 
improvement.  
 
There are no controlled trials in paediatric patients with MDS/MPD. Five (5) patients with MDS/MPD 
associated with PDGFR gene re-arrangements were reported in 4 publications. The age of these patients 
ranged from 3 months to 4 years and imatinib was given at dose 50 mg daily or doses ranging from 92.5 to 
340 mg/m2 daily. All patients achieved complete haematological response, cytogenetic response and/or 
clinical response. 
 
Clinical studies in HES/CEL 
One open-label, multicentre, phase II clinical trial (study B2225) was conducted testing imatinib in diverse 
populations of patients suffering from life-threatening diseases associated with Abl, Kit or PDGFR protein 
tyrosine kinases. In this study, 14 patients with HES/CEL were treated with 100 mg to 1,000 mg of imatinib 
daily. A further 162 patients with HES/CEL, reported in 35 published case reports and case series received 
imatinib at doses from 75 mg to 800 mg daily. Cytogenetic abnormalities were evaluated in 117 of the total 
population of 176 patients. In 61 of these 117 patients FIP1L1-PDGFRα fusion kinase was identified. An 
additional four HES patients were found to be FIP1L1-PDGFRα-positive in other 3 published reports. All 65 
FIP1L1-PDGFRα fusion kinase positive patients achieved a CHR sustained for months (range from 1+ to 
44+ months censored at the time of the reporting). As reported in a recent publication 21 of these 65 patients 
also achieved complete molecular remission with a median follow-up of 28 months (range 13-67 months). 
The age of these patients ranged from 25 to 72 years. Additionally, improvements in symptomatology and 
other organ dysfunction abnormalities were reported by the investigators in the case reports. Improvements 
were reported in cardiac, nervous, skin/subcutaneous tissue, respiratory/thoracic/mediastinal, 
musculoskeletal/connective tissue/vascular, and gastrointestinal organ systems. 
 
There are no controlled trials in paediatric patients with HES/CEL. Three (3) patients with HES and CEL 
associated with PDGFR gene re-arrangements were reported in 3 publications. The age of these patients 
ranged from 2 to 16 years and imatinib was given at dose 300 mg/m2 daily or doses ranging from 200 to 400 
mg daily. All patients achieved complete haematological response, complete cytogenetic response and/or 
complete molecular response.

One phase II, open-label, randomised, uncontrolled multinational study was conducted in patients with 
unresectable or metastatic malignant gastrointestinal stromal tumours (GIST). In this study 147 patients were 
enrolled and randomised to receive either 400 mg or 600 mg orally once daily for up to 36 months. These 
patients ranged in age from 18 to 83 years old and had a pathologic diagnosis of Kit-positive malignant GIST 
that was unresectable and/or metastatic. Immunohistochemistry was routinely performed with Kit antibody 
(A-4502, rabbit polyclonal antiserum, 1:100; DAKO Corporation, Carpinteria, CA) according to analysis by 
an avidin-biotin-peroxidase complex method after antigen retrieval. 
 
The primary evidence of efficacy was based on objective response rates. Tumours were required to be 
measurable in at least one site of disease, and response characterisation based on Southwestern Oncology 
Group (SWOG) criteria. Results are provided in Table 5.

There were no differences in response rates between the two dose groups. A significant number of patients 
who had stable disease at the time of the interim analysis achieved a partial response with longer treatment 
(median follow-up 31 months). Median time to response was 13 weeks (95% C.I. 12–23). Median time to 
treatment failure in responders was 122 weeks (95% C.I 106–147), while in the overall study population it 
was 84 weeks (95% C.I 71–109). The median overall survival has not been reached. The Kaplan-Meier 
estimate for survival after 36-month follow-up is 68%. 
 
In two clinical studies (study B2222 and an intergroup study S0033) the daily dose of imatinib was escalated 
to 800 mg in patients progressing at the lower daily doses of 400 mg or 600 mg. The daily dose was 
escalated to 800 mg in a total of 103 patients; 6 patients achieved a partial response and 21 stabilisation of 
their disease after dose escalation for an overall clinical benefit of 26%. From the safety data available, 
escalating the dose to 800 mg daily in patients progressing at lower doses of 400 mg or 600 mg daily does 
not seem to affect the safety profile of imatinib. 
 
Clinical studies in adjuvant GIST 
In the adjuvant setting, imatinib was investigated in a multicentre, double-blind, long-term, placebo-
controlled phase III study (Z9001) involving 773 patients. The ages of these patients ranged from 18 to 91 
years. Patients were included who had a histological diagnosis of primary GIST expressing Kit protein by 
immunochemistry and a tumour size ≥ 3 cm in maximum dimension, with complete gross resection of 
primary GIST within 14-70 days prior to registration. After resection of primary GIST, patients were 
randomised to one of the two arms: imatinib at 400 mg/day or matching placebo for one year. 
 
The primary endpoint of the study was recurrence-free survival (RFS), defined as the time from date of 
randomisation to the date of recurrence or death from any cause. 
 
Imatinib significantly prolonged RFS, with 75% of patients being recurrence-free at 38 months in the 
imatinib group vs. 20 months in the placebo group (95% CIs, [30 - non-estimable]; [14 - non- estimable], 
respectively); (hazard ratio = 0.398 [0.259-0.610], p<0.0001). At one year the overall RFS was significantly 
better for imatinib (97.7%) vs. placebo (82.3%), (p<0.0001). The risk of recurrence was thus reduced by 
approximately 89% as compared with placebo (hazard ratio = 0.113 [0.049-0.264]).

The risk of recurrence in patients after surgery of their primary GIST was retrospectively assessed based on 
the following prognostic factors: tumour size, mitotic index, tumour location. Mitotic index data were 
available for 556 of the 713 intention-to-treat (ITT) population. The results of subgroup analyses according 
to the United States National Institutes of Health (NIH) and the Armed Forces Institute of Pathology (AFIP) 
risk classifications are shown in Table 6. No benefit was observed in the low and very low risk groups. No 
overall survival benefit has been observed.

A second multicentre, open label phase III study (SSG XVIII/AIO) compared 400 mg/day imatinib 12 
months treatment vs. 36 months treatment in patients after surgical resection of GIST and one of the 
following: tumour diameter > 5 cm and mitotic count > 5/50 high power fields (HPF); or tumour diameter > 
10 cm and any mitotic count or tumour of any size with mitotic count > 10/50 HPF or tumours ruptured into 
the peritoneal cavity. There were a total of 397 patients consented and randomised to the study (199 patients 
on 12-month arm and 198 patients on 36-month arm), median age was 61 years (range 22 to 84 years). The 
median time of follow-up was 54 months (from date of randomisation to data cut-off), with a total of 83 
months between the first patient randomised and the cut-off date. 
  
The primary endpoint of the study was recurrence-free survival (RFS), defined as the time from date of 
randomisation to the date of recurrence or death from any cause. 
 
Thirty-six (36) months of imatinib treatment significantly prolonged RFS compared to 12 months of imatinib 
treatment (with overall Hazard Ratio (HR) = 0.46 [0.32, 0.65], p<0.0001) (Table 7, Figure 1). 
 
In addition, thirty-six (36) months of imatinib treatment significantly prolonged overall survival (OS) 
compared to 12 months of imatinib treatment (HR = 0.45 [0.22, 0.89], p=0.0187) (Table 7, Figure 2). 
 
Longer duration of the treatment (> 36 months) may delay the onset of further recurrences; however the 
impact of this finding on the overall survival remains unknown. 
 
The total number of deaths were 25 for the 12-month treatment arm and 12 for the 36-month treatment arm. 
 
Treatment with imatinib for 36 months was superior to treatment for 12 months in the ITT analysis, i.e. 
including the entire study population. In a planned subgroup analysis by mutation type, the HR for RFS for 
36 months of treatment for patients with mutations of exon 11 was 0.35 [95% CI: 0.22, 0.56]. No 
conclusions can be drawn for other less common mutation subgroups due to the low number of observed 
events.

There are no controlled trials in paediatric patients with c-Kit positive GIST. Seventeen (17) patients with 
GIST (with or without Kit and PDGFR mutations) were reported in 7 publications. The age of these patients 
ranged from 8 to 18 years and imatinib was given in both adjuvant and metastatic settings at doses ranging 
from 300 to 800 mg daily. The majority of paediatric patients treated for GIST lacked data confirming c-kit 
or PDGFR mutations which may have led to mixed clinical outcomes.

Clinical studies in DFSP 
One phase II, open label, multicentre clinical trial (study B2225) was conducted including 12 patients with 
DFSP treated with imatinib 800 mg daily. The age of the DFSP patients ranged from 23 to 75 years; DFSP 
was metastatic, locally recurrent following initial resective surgery and not considered amenable to further 
resective surgery at the time of study entry. The primary evidence of efficacy was based on objective 
response rates. Out of the 12 patients enrolled, 9 responded, one completely and 8 partially. Three of the 
partial responders were subsequently rendered disease free by surgery. The median duration of therapy in 
study B2225 was 6.2 months, with a maximum duration of 24.3 months. A further 6 DFSP patients treated 
with imatinib were reported in 5 published case reports, their ages ranging from 18 months to 49 years. The 
adult patients reported in the published literature were treated with either 400 mg (4 cases) or 800 mg (1 
case) imatinib daily. Five (5) patients responded, 3 completely and 2 partially. The median duration of 
therapy in the published literature ranged between 4 weeks and more than 20 months. The translocation 
t(17:22)[(q22:q13)], or its gene product, was present in nearly all responders to imatinib treatment. 
 
There are no controlled trials in paediatric patients with DFSP. Five (5) patients with DFSP and PDGFR 
gene re-arrangements were reported in 3 publications. The age of these patients ranged from newborn to 14 
years and imatinib was given at dose 50 mg daily or doses ranging from 400 to 520 mg/m2 daily. All patients 
achieved partial and/or complete response. 
 
5.2 Pharmacokinetic properties 
 
Pharmacokinetics of imatinib 
The pharmacokinetics of imatinib have been evaluated over a dosage range of 25 to 1,000 mg. Plasma 
pharmacokinetic profiles were analysed on day 1 and on either day 7 or day 28, by which time plasma 
concentrations had reached steady state. 
 
Absorption 
Mean absolute bioavailability for the capsule formulation is 98%. There was high between-patient variability 
in plasma imatinib AUC levels after an oral dose. When given with a high-fat meal, the rate of absorption of 
imatinib was minimally reduced (11% decrease in Cmax and prolongation of tmax by 1.5 h), with a small 
reduction in AUC (7.4%) compared to fasting conditions. The effect of prior gastrointestinal surgery on drug 
absorption has not been investigated. 
 
Distribution 
At clinically relevant concentrations of imatinib, binding to plasma proteins was approximately 95% on the 
basis of in vitro experiments, mostly to albumin and alpha-acid-glycoprotein, with little binding to 
lipoprotein.  
 
Biotransformation 
The main circulating metabolite in humans is the N-demethylated piperazine derivative, which shows similar 
in vitro potency to the parent. The plasma AUC for this metabolite was found to be only 16% of the AUC for 
imatinib. The plasma protein binding of the N-demethylated metabolite is similar to that of the parent 
compound. 
 
Imatinib and the N-demethyl metabolite together accounted for about 65% of the circulating radioactivity 
(AUC(0-48h)). The remaining circulating radioactivity consisted of a number of minor metabolites. 
 
The in vitro results showed that CYP3A4 was the major human P450 enzyme catalysing the 
biotransformation of imatinib. Of a panel of potential comedications (acetaminophen, aciclovir, allopurinol, 
amphotericin, cytarabine, erythromycin, fluconazole, hydroxyurea, norfloxacin, penicillin V) only 
erythromycin (IC50 50 μM) and fluconazole (IC50 118 μM) showed inhibition of imatinib metabolism which 
could have clinical relevance. 
 
Imatinib was shown in vitro to be a competitive inhibitor of marker substrates for CYP2C9, CYP2D6 and 
CYP3A4/5. Ki values in human liver microsomes were 27, 7.5 and 7.9 µmol/l, respectively. Maximal plasma

concentrations of imatinib in patients are 2-4 µmol/l, consequently an inhibition of CYP2D6 and/or 
CYP3A4/5-mediated metabolism of co-administered drugs is possible. Imatinib did not interfere with the 
biotransformation of 5-fluorouracil, but it inhibited paclitaxel metabolism as a result of competitive 
inhibition of CYP2C8 (Ki = 34.7 μM). This K i value is far higher than the expected plasma levels of 
imatinib in patients; consequently no interaction is expected upon co-administration of either 5-fluorouracil 
or paclitaxel and imatinib. 
 
Elimination 
Based on the recovery of compound(s) after an oral 14C-labelled dose of imatinib, approximately 81% of the 
dose was recovered within 7 days in faeces (68% of dose) and urine (13% of dose). Unchanged imatinib 
accounted for 25% of the dose (5% urine, 20% faeces), the remainder being metabolites. 
 
Plasma pharmacokinetics 
Following oral administration in healthy volunteers, the t½ was approximately 18 h, suggesting that once-
daily dosing is appropriate. The increase in mean AUC with increasing dose was linear and dose proportional 
in the range of 25-1,000 mg imatinib after oral administration. There was no change in the kinetics of 
imatinib on repeated dosing, and accumulation was 1.5-2.5-fold at steady state when dosed once daily. 
 
Pharmacokinetics in GIST patients 
In patients with GIST steady-state exposure was 1.5-fold higher than that observed for CML patients for the 
same dosage (400 mg daily). Based on preliminary population pharmacokinetic analysis in GIST patients, 
there were three variables (albumin, WBC and bilirubin) found to have a statistically significant relationship 
with imatinib pharmacokinetics. Decreased values of albumin caused a reduced clearance (CL/f); and higher 
levels of WBC led to a reduction of CL/f. However, these associations are not sufficiently pronounced to 
warrant dose adjustment. In this patient population, the presence of hepatic metastases could potentially lead 
to hepatic insufficiency and reduced metabolism. 
 
Population pharmacokinetics 
Based on population pharmacokinetic analysis in CML patients, there was a small effect of age on the 
volume of distribution (12% increase in patients > 65 years old). This change is not thought to be clinically 
significant. The effect of bodyweight on the clearance of imatinib is such that for a patient weighing 50 kg 
the mean clearance is expected to be 8.5 l/h, while for a patient weighing 100 kg the clearance will rise to 
11.8 l/h. These changes are not considered sufficient to warrant dose adjustment based on kg bodyweight. 
There is no effect of gender on the kinetics of imatinib. 
 
Pharmacokinetics in children 
As in adult patients, imatinib was rapidly absorbed after oral administration in paediatric patients in both 
phase I and phase II studies. Dosing in children at 260 and 340 mg/m2/day achieved the same exposure, 
respectively, as doses of 400 mg and 600 mg in adult patients. The comparison of AUC(0-24) on day 8 and day 
1 at the 340 mg/m2/day dose level revealed a 1.7-fold drug accumulation after repeated once-daily dosing. 
 
Based on pooled population pharmacokinetic analysis in paediatric patients with haematological disorders 
(CML, Ph+ALL, or other haematological disorders treated with imatinib), clearance of imatinib increases 
with increasing body surface area (BSA). After correcting for the BSA effect, other demographics such as 
age, body weight and body mass index did not have clinically significant effects on the exposure of imatinib. 
The analysis confirmed that exposure of imatinib in paediatric patients receiving 260 mg/m2 once daily (not 
exceeding 400 mg once daily) or 340 mg/m2 once daily (not exceeding 600 mg once daily) were similar to 
those in adult patients who received imatinib 400 mg or 600 mg once daily. 
 
Organ function impairment 
Imatinib and its metabolites are not excreted via the kidney to a significant extent. Patients with mild and 
moderate impairment of renal function appear to have a higher plasma exposure than patients with normal 
renal function. The increase is approximately 1.5- to 2-fold, corresponding to a 1.5-fold elevation of plasma 
AGP, to which imatinib binds strongly. The free drug clearance of imatinib is probably similar between

patients with renal impairment and those with normal renal function, since renal excretion represents only a 
minor elimination pathway for imatinib (see sections 4.2 and 4.4).  
 
Although the results of pharmacokinetic analysis showed that there is considerable inter-subject variation, 
the mean exposure to imatinib did not increase in patients with varying degrees of liver dysfunction as 
compared to patients with normal liver function (see sections 4.2, 4.4 and 4.8). 
 
5.3 Preclinical safety data 
 
The preclinical safety profile of imatinib was assessed in rats, dogs, monkeys and rabbits. 
 
Multiple dose toxicity studies revealed mild to moderate haematological changes in rats, dogs and monkeys, 
accompanied by bone marrow changes in rats and dogs. 
 
The liver was a target organ in rats and dogs. Mild to moderate increases in transaminases and slight 
decreases in cholesterol, triglycerides, total protein and albumin levels were observed in both species. No 
histopathological changes were seen in rat liver. Severe liver toxicity was observed in dogs treated for 2 
weeks, with elevated liver enzymes, hepatocellular necrosis, bile duct necrosis, and bile duct hyperplasia. 
 
Renal toxicity was observed in monkeys treated for 2 weeks, with focal mineralisation and dilation of the 
renal tubules and tubular nephrosis. Increased blood urea nitrogen (BUN) and creatinine were observed in 
several of these animals. In rats, hyperplasia of the transitional epithelium in the renal papilla and in the 
urinary bladder was observed at doses ≥ 6 mg/kg in the 13-week study, without changes in serum or urinary 
parameters. An increased rate of opportunistic infections was observed with chronic imatinib treatment. 
 
In a 39-week monkey study, no NOAEL (no observed adverse effect level) was established at the lowest 
dose of 15 mg/kg, approximately one-third the maximum human dose of 800 mg based on body surface. 
Treatment resulted in worsening of normally suppressed malarial infections in these animals. 
 
Imatinib was not considered genotoxic when tested in an in vitro bacterial cell assay (Ames test), an in vitro 
mammalian cell assay (mouse lymphoma) and an in vivo rat micronucleus test. Positive genotoxic effects 
were obtained for imatinib in an in vitro mammalian cell assay (Chinese hamster ovary) for clastogenicity 
(chromosome aberration) in the presence of metabolic activation. Two intermediates of the manufacturing 
process, which are also present in the final product, are positive for mutagenesis in the Ames assay. One of 
these intermediates was also positive in the mouse lymphoma assay. 
 
In a study of fertility, in male rats dosed for 70 days prior to mating, testicular and epididymal weights and 
percent motile sperm were decreased at 60 mg/kg, approximately equal to the maximum clinical dose of 800 
mg/day, based on body surface area. This was not seen at doses ≤ 20 mg/kg. A slight to moderate reduction 
in spermatogenesis was also observed in the dog at oral doses ≥ 30 mg/kg. When female rats were dosed 14 
days prior to mating and through to gestational day 6, there was no effect on mating or on number of 
pregnant females. At a dose of 60 mg/kg, female rats had significant post-implantation foetal loss and a 
reduced number of live foetuses. This was not seen at doses ≤ 20 mg/kg. 
 
In an oral pre- and postnatal development study in rats, red vaginal discharge was noted in the 45 mg/kg/day 
group on either day 14 or day 15 of gestation. At the same dose, the number of stillborn pups as well as those 
dying between postpartum days 0 and 4 was increased. In the F1 offspring, at the same dose level, mean 
body weights were reduced from birth until terminal sacrifice and the number of litters achieving criterion 
for preputial separation was slightly decreased. F1 fertility was not affected, while an increased number of 
resorptions and a decreased number of viable foetuses was noted at 45 mg/kg/day. The no observed effect 
level (NOEL) for both the maternal animals and the F1 generation was 15 mg/kg/day (one quarter of the 
maximum human dose of 800 mg). 
 
Imatinib was teratogenic in rats when administered during organogenesis at doses ≥ 100 mg/kg, 
approximately equal to the maximum clinical dose of 800 mg/day, based on body surface area. Teratogenic

effects included exencephaly or encephalocele, absent/reduced frontal and absent parietal bones. These 
effects were not seen at doses ≤ 30 mg/kg. 
 
No new target organs were identified in the rat juvenile development toxicology study (day 10 to 70 
postpartum) with respect to the known target organs in adult rats. In the juvenile toxicology study, effects 
upon growth, delay in vaginal opening and preputial separation were observed at approximately 0.3 to 2 
times the average paediatric exposure at the highest recommended dose of 340 mg/m2. In addition, mortality 
was observed in juvenile animals (around weaning phase) at approximately 2 times the average paediatric 
exposure at the highest recommended dose of 340 mg/m2. 
 
In the 2-year rat carcinogenicity study administration of imatinib at 15, 30 and 60 mg/kg/day resulted in a 
statistically significant reduction in the longevity of males at 60 mg/kg/day and females at ≥30 mg/kg/day. 
Histopathological examination of decedents revealed cardiomyopathy (both sexes), chronic progressive 
nephropathy (females) and preputial gland papilloma as principal causes of death or reasons for sacrifice. 
Target organs for neoplastic changes were the kidneys, urinary bladder, urethra, preputial and clitoral gland, 
small intestine, parathyroid glands, adrenal glands and non-glandular stomach. 
 
Papilloma/carcinoma of the preputial/clitoral gland were noted from 30 mg/kg/day onwards, representing 
approximately 0.5 or 0.3 times the human daily exposure (based on AUC) at 400 mg/day or 800 mg/day, 
respectively, and 0.4 times the daily exposure in children (based on AUC) at 340 mg/m2/day. The no 
observed effect level (NOEL) was 15 mg/kg/day. The renal adenoma/carcinoma, the urinary bladder and 
urethra papilloma, the small intestine adenocarcinomas, the parathyroid glands adenomas, the benign and 
malignant medullary tumours of the adrenal glands and the non-glandular stomach papillomas/carcinomas 
were noted at 60 mg/kg/day, representing approximately 1.7 or 1 times the human daily exposure (based on 
AUC) at 400 mg/day or 800 mg/day, respectively, and 1.2 times the daily exposure in children (based on 
AUC) at 340 mg/m2/day. The no observed effect level (NOEL) was 30 mg/kg/day. 
 
The mechanism and relevance of these findings in the rat carcinogenicity study for humans are not yet 
clarified. 
 
Non-neoplastic lesions not identified in earlier preclinical studies were the cardiovascular system, pancreas, 
endocrine organs and teeth. The most important changes included cardiac hypertrophy and dilatation, leading 
to signs of cardiac insufficiency in some animals. 
 
The active substance imatinib demonstrates an environmental risk for sediment organisms.

Imatinib Teva B.V. 100 mg film-coated tablets 
Imatinib 

 
 
Read all of this leaflet carefully before you start taking this medicine because it contains important 
information for you.  
- Keep this leaflet. You may need to read it again.  
- If you have any further questions, ask your doctor, pharmacist or nurse.  
- This medicine has been prescribed for you only. Do not pass it on to others. It may harm them, even if 

their signs of illness are the same as yours.  
- If you get any side effects, talk to your doctor, pharmacist or nurse. This includes any possible side 

effects not listed in this leaflet. See section 4. 
 
What is in this leaflet  
 
1. What Imatinib Teva B.V. is and what it is used for  
2. What you need to know before you take Imatinib Teva B.V. 
3. How to take Imatinib Teva B.V.

5. How to store Imatinib Teva B.V. 
6. Contents of the pack and other information  
 
 
1. What Imatinib Teva B.V. is and what it is used for  
 
Imatinib Teva B.V. is a medicine containing an active substance called imatinib. This medicine works by 
inhibiting the growth of abnormal cells in the diseases listed below. These include some types of cancer. 
 
Imatinib Teva B.V. is a treatment for: 
 
- Chronic myeloid leukaemia (CML). Leukaemia is a cancer of white blood cells. These white cells 

usually help the body to fight infection. Chronic myeloid leukaemia is a form of leukaemia in which 
certain abnormal white cells (named myeloid cells) start growing out of control. 

 
In adult patients, Imatinib Teva B.V. is intended for use in the most advanced phase of the disease (blast 
crisis). In children and adolescents, Imatinib Teva B.V. can be used in different phases of the disease 
(chronic, accelerated phase and blast crisis). 
 
Imatinib Teva is also a treatment for adults and children for:  
- Philadelphia chromosome positive acute lymphoblastic leukaemia (Ph-positive ALL). Leukaemia 

is a cancer of white blood cells. These white cells usually help the body to fight infection. Acute 
lymphoblastic leukaemia is a form of leukaemia in which certain abnormal white cells (named 
lymphoblasts) start growing out of control. Imatinib Teva B.V. inhibits the growth of these cells.  

 
Imatinib Teva B.V. is also a treatment for adults for: 
 
- Myelodysplastic/myeloproliferative diseases (MDS/MPD). These are a group of blood diseases in 

which some blood cells start growing out of control. Imatinib Teva B.V. inhibits the growth of these 
cells in a certain subtype of these diseases.  

- Hypereosinophilic syndrome (HES) and/or chronic eosinophilic leukaemia (CEL). These are 
blood diseases in which some blood cells (named eosinophils) start growing out of control. Imatinib 
Teva B.V. inhibits the growth of these cells in a certain subtype of these diseases.  

- Gastrointestinal stromal tumours (GIST). GIST is a cancer of the stomach and bowels. It arises 
from uncontrolled cell growth of the supporting tissues of these organs.

- Dermatofibrosarcoma protuberans (DFSP). DFSP is a cancer of the tissue beneath the skin in 
which some cells start growing out of control. Imatinib Teva B.V. inhibits the growth of these cells. 

 
In the rest of this leaflet, we will use the abbreviations when talking about these diseases. 
 
If you have any questions about how Imatinib Teva B.V. works or why this medicine has been prescribed for 
you, ask your doctor.  
 
 
2. What you need to know before you take Imatinib Teva B.V. 
 
Imatinib Teva B.V. will only be prescribed to you by a doctor with experience in medicines to treat blood 
cancers or solid tumours. 
 
Follow all your doctor’s instructions carefully, even if they differ from the general information contained in 
this leaflet.  
 
Do not take Imatinib Teva B.V. 
- if you are allergic to imatinib or any of the other ingredients of this medicine (listed in section 6).  
 
If this applies to you, tell your doctor without taking Imatinib Teva B.V.  
 
If you think you may be allergic but are not sure, ask your doctor for advice.  
 
Warnings and precautions 
Talk to your doctor before taking Imatinib Teva B.V.:  
- if you have or have ever had a liver, kidney or heart problem.  
- if you are taking the medicine levothyroxine because your thyroid has been removed.  
- if you have ever had or might now have a hepatitis B infection. This is because Imatinib Teva B.V. 

could cause hepatitis B to become active again, which can be fatal in some cases. Patients will be 
carefully checked by their doctor for signs of this infection before treatment is started. 

 
If any of these apply to you, tell your doctor before taking Imatinib Teva B.V. 
 
During treatment with Imatinib Teva B.V., tell your doctor straight away if you put on weight very 
quickly. Imatinib Teva B.V. may cause your body to retain water (severe fluid retention).  
 
While you are taking Imatinib Teva B.V. your doctor will regularly check whether the medicine is working. 
You will also have blood tests and be weighed regularly.  
 
Children and adolescents 
Imatinib Teva B.V. is also a treatment for children with CML. There is no experience in children with CML 
below 2 years of age. There is limited experience in children with Ph-positive ALL and very limited 
experience in children with MDS/MPD, DFSP, GIST and HES/CEL. 
 
Some children and adolescents taking Imatinib Teva B.V. may have slower than normal growth. The doctor 
will monitor the growth at regular visits.  
 
Other medicines and Imatinib Teva B.V. 
Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines, 
including medicines obtained without a prescription (such as paracetamol) and including herbal medicines 
(such as St. John’s Wort). Some medicines can interfere with the effect of Imatinib Teva B.V. when taken 
together. They may increase or decrease the effect of Imatinib Teva B.V., either leading to increased side 
effects or making Imatinib Teva B.V. less effective. Imatinib Teva B.V. may do the same to some other 
medicines.  
 
Tell your doctor if you are using medicines that prevent the formation of blood clots.

3. How to take Imatinib Teva B.V. 
 
Your doctor has prescribed Imatinib Teva B.V. because you suffer from a serious condition. Imatinib Teva 
B.V. can help you to fight this condition.  
 
However, always take this medicine exactly as your doctor or pharmacist has told you. It is important that 
you do this as long as your doctor or pharmacist tells you to. Check with your doctor or pharmacist if you are 
not sure. 
 
Do not stop taking Imatinib Teva B.V. unless your doctor tells you to. If you are not able to take the 
medicine as your doctor prescribed or you feel you do not need it anymore, contact your doctor straight 
away.  
 
How much Imatinib Teva B.V. to take  
 
Use in adults  
Your doctor will tell you exactly how many tablets of Imatinib Teva B.V. to take.  
 
- If you are being treated for CML:  

The usual starting dose is 600 mg to be taken as 6 tablets once a day. 
 
- If you are being treated for GIST: 

The starting dose is 400 mg, to be taken as 4 tablets once a day. 
 
For CML and GIST, your doctor may prescribe a higher or lower dose depending on how you respond to the 
treatment. If your daily dose is 800 mg (8 tablets), you should take 4 tablets in the morning and 4 tablets in 
the evening.

evening. 

 
Use in children and adolescents 
The doctor will tell you how many tablets of Imatinib Teva B.V. to give to your child. The amount of 
Imatinib Teva B.V. given will depend on your child’s condition, body weight and height. The total daily 
dose in children must not exceed 800 mg with CML and 600 mg with Ph+ALL. The treatment can either be 
given to your child as a once-daily dose or alternatively the daily dose can be split into two administrations 
(half in the morning and half in the evening).  
 
When and how to take Imatinib Teva B.V.  
- Take Imatinib Teva B.V. with a meal. This will help protect you from stomach problems when 

taking Imatinib Teva B.V. 
- Swallow the tablets whole with a large glass of water.  
 
If you are unable to swallow the tablets, you can dissolve them in a glass of still water or apple juice:  
• Use about 50 ml for each 100 mg tablet.  
• Stir with a spoon until the tablets have completely dissolved.  
• Once the tablet has dissolved, drink everything in the glass straight away. Traces of the dissolved 

tablets may be left behind in the glass.  
 
The tablet can be divided into equal doses. 
 
How long to take Imatinib Teva B.V. 
Keep taking Imatinib Teva B.V. every day for as long as your doctor tells you.  
 
If you take more Imatinib Teva B.V. than you should  
If you have accidentally taken too many tablets, talk to your doctor straight away. You may require medical 
attention. Take the medicine pack with you.  
 
If you forget to take Imatinib Teva B.V. 
- If you forget a dose, take it as soon as you remember. However if it is nearly time for the next dose, 

skip the missed dose.  
- Then continue with your normal schedule.  
- Do not take a double dose to make up a forgotten dose.  
 
If you have any further questions on the use of this medicine, ask your doctor, pharmacist or nurse.

- This medicine has been prescribed for you only. Do not pass it on to others. It may harm them, even if 

their signs of illness are the same as yours.  
- If you get any side effects, talk to your doctor, pharmacist or nurse. This includes any possible side

1. What Imatinib Teva B.V. is and what it is used for  
2. What you need to know before you take Imatinib Teva B.V. 
3. How to take Imatinib Teva B.V.

6. Contents of the pack and other information  
 
 
1. What Imatinib Teva B.V. is and what it is used for  
 
Imatinib Teva B.V. is a medicine containing an active substance called imatinib. This medicine works by 
inhibiting the growth of abnormal cells in the diseases listed below. These include some types of cancer. 
 
Imatinib Teva B.V. is a treatment for: 
 
- Chronic myeloid leukaemia (CML). Leukaemia is a cancer of white blood cells. These white cells 

usually help the body to fight infection. Chronic myeloid leukaemia is a form of leukaemia in which 
certain abnormal white cells (named myeloid cells) start growing out of control. 
 

In adult patients, Imatinib Teva B.V. is intended for use in the most advanced phase of the disease (blast 
crisis). In children and adolescents, Imatinib Teva B.V. can be used in different phases of the disease 
(chronic, accelerated phase and blast crisis). 
 
Imatinib Teva is also a treatment for adults and children for:  
- Philadelphia chromosome positive acute lymphoblastic leukaemia (Ph-positive ALL). Leukaemia 

is a cancer of white blood cells. These white cells usually help the body to fight infection. Acute 
lymphoblastic leukaemia is a form of leukaemia in which certain abnormal white cells (named 
lymphoblasts) start growing out of control. Imatinib Teva B.V. inhibits the growth of these cells.  

 
Imatinib Teva B.V. is also a treatment for adults for: 
 
- Myelodysplastic/myeloproliferative diseases (MDS/MPD). These are a group of blood diseases in 

which some blood cells start growing out of control. Imatinib Teva B.V. inhibits the growth of these 
cells in a certain subtype of these diseases.  

- Hypereosinophilic syndrome (HES) and/or chronic eosinophilic leukaemia (CEL). These are 
blood diseases in which some blood cells (named eosinophils) start growing out of control. Imatinib 
Teva B.V. inhibits the growth of these cells in a certain subtype of these diseases. 

- Gastrointestinal stromal tumours (GIST). GIST is a cancer of the stomach and bowels. It arises 
from uncontrolled cell growth of the supporting tissues of these organs.

- Dermatofibrosarcoma protuberans (DFSP). DFSP is a cancer of the tissue beneath the skin in 
which some cells start growing out of control. Imatinib Teva B.V. inhibits the growth of these cells. 

 
In the rest of this leaflet, we will use the abbreviations when talking about these diseases. 
 
If you have any questions about how Imatinib Teva B.V. works or why this medicine has been prescribed for 
you, ask your doctor.  
 
 
2. What you need to know before you take Imatinib Teva B.V. 
 
Imatinib Teva B.V. will only be prescribed to you by a doctor with experience in medicines to treat blood 
cancers or solid tumours. 
 
Follow all your doctor’s instructions carefully, even if they differ from the general information contained in 
this leaflet.  
 
Do not take Imatinib Teva B.V. 
- if you are allergic to imatinib or any of the other ingredients of this medicine (listed in section 6).  
 
If this applies to you, tell your doctor without taking Imatinib Teva B.V.  
 
If you think you may be allergic but are not sure, ask your doctor for advice.  
 
Warnings and precautions 
Talk to your doctor before taking Imatinib Teva B.V.:  
- if you have or have ever had a liver, kidney or heart problem.  
- if you are taking the medicine levothyroxine because your thyroid has been removed.  
- if you have ever had or might now have a hepatitis B infection. This is because Imatinib Teva B.V. 

could cause hepatitis B to become active again, which can be fatal in some cases. Patients will be 
carefully checked by their doctor for signs of this infection before treatment is started. 

 
If any of these apply to you, tell your doctor before taking Imatinib Teva B.V. 
 
During treatment with Imatinib Teva B.V., tell your doctor straight away if you put on weight very 
quickly. Imatinib Teva B.V. may cause your body to retain water (severe fluid retention).  
 
While you are taking Imatinib Teva B.V. your doctor will regularly check whether the medicine is working. 
You will also have blood tests and be weighed regularly.  
 
Children and adolescents 
Imatinib Teva B.V. is also a treatment for children with CML. There is no experience in children with CML 
below 2 years of age. There is limited experience in children with Ph-positive ALL and very limited 
experience in children with MDS/MPD, DFSP, GIST and HES/CEL. 
 
Some children and adolescents taking Imatinib Teva B.V. may have slower than normal growth. The doctor 
will monitor the growth at regular visits.  
 
Other medicines and Imatinib Teva B.V. 
Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines, 
including medicines obtained without a prescription (such as paracetamol) and including herbal medicines 
(such as St. John’s Wort). Some medicines can interfere with the effect of Imatinib Teva B.V. when taken 
together. They may increase or decrease the effect of Imatinib Teva B.V., either leading to increased side 
effects or making Imatinib Teva B.V. less effective. Imatinib Teva B.V. may do the same to some other 
medicines.  
 
Tell your doctor if you are using medicines that prevent the formation of blood clots.

or use any tools or machines until you are feeling well again.  
 
 
3. How to take Imatinib Teva B.V. 
 
Your doctor has prescribed Imatinib Teva B.V. because you suffer from a serious condition. Imatinib Teva 
B.V. can help you to fight this condition.  
 
However, always take this medicine exactly as your doctor or pharmacist has told you. It is important that 
you do this as long as your doctor or pharmacist tells you to. Check with your doctor or pharmacist if you are 
not sure. 
 
Do not stop taking Imatinib Teva B.V. unless your doctor tells you to. If you are not able to take the 
medicine as your doctor prescribed or you feel you do not need it anymore, contact your doctor straight 
away.  
 
How much Imatinib Teva B.V. to take  
 
Use in adults  
Your doctor will tell you exactly how many tablets of Imatinib Teva B.V. to take.  
 
- If you are being treated for CML: 

The usual starting dose is 600 mg to be taken as one tablet of 400 mg plus 2 tablets of 100 mg once a 
day. 

 
- If you are being treated for GIST: 

The starting dose is 400 mg, to be taken as one tablet once a day. 
 
For CML and GIST, your doctor may prescribe a higher or lower dose depending on how you respond to the 
treatment. If your daily dose is 800 mg (2 tablets), you should take one tablet in the morning and a second 
tablet in the evening.

Use in children and adolescents 
The doctor will tell you how many tablets of Imatinib Teva B.V. to give to your child. The amount of 
Imatinib Teva B.V. given will depend on your child’s condition, body weight and height. The total daily 
dose in children must not exceed 800 mg with CML and 600 mg with Ph+ALL. The treatment can either be 
given to your child as a once-daily dose or alternatively the daily dose can be split into two administrations 
(half in the morning and half in the evening).

If you are unable to swallow the tablets, you can dissolve them in a glass of still water or apple juice:  
• Use about 200 ml for each 400 mg tablet.  
• Stir with a spoon until the tablets have completely dissolved.  
• Once the tablet has dissolved, drink everything in the glass straight away. Traces of the dissolved 

tablets may be left behind in the glass.  
 
The tablet can be divided into equal doses. 
 
How long to take Imatinib Teva B.V. 
Keep taking Imatinib Teva B.V. every day for as long as your doctor tells you.  
 
If you take more Imatinib Teva B.V. than you should  
If you have accidentally taken too many tablets, talk to your doctor straight away. You may require medical 
attention. Take the medicine pack with you.  
 
If you forget to take Imatinib Teva B.V. 
- If you forget a dose, take it as soon as you remember. However if it is nearly time for the next dose, 

skip the missed dose.  
- Then continue with your normal schedule.  
- Do not take a double dose to make up a forgotten dose.  
 
If you have any further questions on the use of this medicine, ask your doctor, pharmacist or nurse.

1. What Imatinib Teva B.V. is and what it is used for  
 
Imatinib Teva B.V. is a medicine containing an active substance called imatinib. This medicine works by 
inhibiting the growth of abnormal cells in the diseases listed below. These include some types of cancer. 
 
Imatinib Teva B.V. is a treatment for: 
 
- Chronic myeloid leukaemia (CML). Leukaemia is a cancer of white blood cells. These white cells 

usually help the body to fight infection. Chronic myeloid leukaemia is a form of leukaemia in which 
certain abnormal white cells (named myeloid cells) start growing out of control. 
 

In adult patients, Imatinib Teva B.V. is intended for use in the most advanced phase of the disease (blast 
crisis). In children and adolescents, Imatinib Teva B.V. can be used in different phases of the disease 
(chronic, accelerated phase and blast crisis). 
 
Imatinib Teva is also a treatment for adults and children for:  
- Philadelphia chromosome positive acute lymphoblastic leukaemia (Ph-positive ALL). Leukaemia 

is a cancer of white blood cells. These white cells usually help the body to fight infection. Acute 
lymphoblastic leukaemia is a form of leukaemia in which certain abnormal white cells (named 
lymphoblasts) start growing out of control. Imatinib Teva B.V. inhibits the growth of these cells.  

 
Imatinib Teva B.V. is also a treatment for adults for: 
 
- Myelodysplastic/myeloproliferative diseases (MDS/MPD). These are a group of blood diseases in 

which some blood cells start growing out of control. Imatinib Teva B.V. inhibits the growth of these 
cells in a certain subtype of these diseases.  

- Hypereosinophilic syndrome (HES) and/or chronic eosinophilic leukaemia (CEL). These are 
blood diseases in which some blood cells (named eosinophils) start growing out of control. Imatinib 
Teva B.V. inhibits the growth of these cells in a certain subtype of these diseases. 

- Gastrointestinal stromal tumours (GIST). GIST is a cancer of the stomach and bowels. It arises 
from uncontrolled cell growth of the supporting tissues of these organs.

- Dermatofibrosarcoma protuberans (DFSP). DFSP is a cancer of the tissue beneath the skin in 
which some cells start growing out of control. Imatinib Teva B.V. inhibits the growth of these cells.  

 
In the rest of this leaflet, we will use the abbreviations when talking about these diseases. 
 
If you have any questions about how Imatinib Teva B.V. works or why this medicine has been prescribed for 
you, ask your doctor.  
 
 
2. What you need to know before you take Imatinib Teva B.V. 
 
Imatinib Teva B.V. will only be prescribed to you by a doctor with experience in medicines to treat blood 
cancers or solid tumours.  
 
Follow all your doctor’s instructions carefully, even if they differ from the general information contained in 
this leaflet.  
 
Do not take Imatinib Teva B.V. 
- if you are allergic to imatinib or any of the other ingredients of this medicine (listed in section 6).  
 
If this applies to you, tell your doctor without taking Imatinib Teva B.V.  
 
If you think you may be allergic but are not sure, ask your doctor for advice.  
 
Warnings and precautions 
Talk to your doctor before taking Imatinib Teva B.V.:  
- if you have or have ever had a liver, kidney or heart problem.  
- if you are taking the medicine levothyroxine because your thyroid has been removed.  
- if you have ever had or might now have a hepatitis B infection. This is because Imatinib Teva B.V. 

could cause hepatitis B to become active again, which can be fatal in some cases. Patients will be 
carefully checked by their doctor for signs of this infection before treatment is started. 

 
If any of these apply to you, tell your doctor before taking Imatinib Teva B.V. 
 
During treatment with Imatinib Teva B.V., tell your doctor straight away if you put on weight very 
quickly. Imatinib Teva B.V. may cause your body to retain water (severe fluid retention).  
 
While you are taking Imatinib Teva B.V. your doctor will regularly check whether the medicine is working. 
You will also have blood tests and be weighed regularly.  
 
Children and adolescents  
Imatinib Teva B.V. is also a treatment for children with CML. There is no experience in children with CML 
below 2 years of age. There is limited experience in children with Ph-positive ALL and very limited 
experience in children with MDS/MPD, DFSP, GIST and HES/CEL. 
 
Some children and adolescents taking Imatinib Teva B.V. may have slower than normal growth. The doctor 
will monitor the growth at regular visits.  
 
Other medicines and Imatinib Teva B.V. 
Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines, 
including medicines obtained without a prescription (such as paracetamol) and including herbal medicines 
(such as St. John’s Wort). Some medicines can interfere with the effect of Imatinib Teva B.V. when taken 
together. They may increase or decrease the effect of Imatinib Teva B.V., either leading to increased side 
effects or making Imatinib Teva B.V. less effective. Imatinib Teva B.V. may do the same to some other 
medicines.  
 
Tell your doctor if you are using medicines that prevent the formation of blood clots.

or use any tools or machines until you are feeling well again.  
 
 
3. How to take Imatinib Teva B.V. 
 
Your doctor has prescribed Imatinib Teva B.V. because you suffer from a serious condition. Imatinib Teva 
B.V. can help you to fight this condition.  
 
However, always take this medicine exactly as your doctor or pharmacist has told you. It is important that 
you do this as long as your doctor or pharmacist tells you to. Check with your doctor or pharmacist if you are 
not sure.  
 
Do not stop taking Imatinib Teva B.V. unless your doctor tells you to. If you are not able to take the 
medicine as your doctor prescribed or you feel you do not need it anymore, contact your doctor straight 
away.  
 
How much Imatinib Teva B.V. to take

- If you are being treated for GIST: 
The starting dose is 400 mg, to be taken as 4 capsules once a day.

treatment. If your daily dose is 800 mg (8 capsules), you should take 4 capsules in the morning and 4 
capsules in the evening.

evening. 

 
Use in children and adolescents 
The doctor will tell you how many capsules of Imatinib Teva B.V. to give to your child. The amount of 
Imatinib Teva B.V. given will depend on your child’s condition, body weight and height. The total daily 
dose in children must not exceed 800 mg with CML and 600 mg with Ph+ALL. The treatment can either be 
given to your child as a once-daily dose or alternatively the daily dose can be split into two administrations 
(half in the morning and half in the evening).

- If you are unable to swallow the capsules, you can open them up and pour the powder into a glass of 

still water or apple juice.  
- If you are a woman who is pregnant or might get pregnant and are trying to open the capsules, you 

should handle the contents with caution in order to avoid skin-eye contact or inhalation. You should 
wash your hands immediately after opening the capsules.  

 
How long to take Imatinib Teva B.V. 
Keep taking Imatinib Teva B.V. every day for as long as your doctor tells you.  
 
If you take more Imatinib Teva B.V. than you should  
If you have accidentally taken too many capsules, talk to your doctor straight away. You may require 
medical attention. Take the medicine pack with you. 
 
If you forget to take Imatinib Teva B.V. 
- If you forget a dose, take it as soon as you remember. However if it is nearly time for the next dose, 

skip the missed dose.  
- Then continue with your normal schedule.  
- Do not take a double dose to make up a forgotten dose.  
 
If you have any further questions on the use of this medicine, ask your doctor, pharmacist or nurse.

1. What Imatinib Teva B.V. is and what it is used for  
 
Imatinib Teva B.V. is a medicine containing an active substance called imatinib. This medicine works by 
inhibiting the growth of abnormal cells in the diseases listed below. These include some types of cancer. 
 
Imatinib Teva B.V. is a treatment for: 
- Chronic myeloid leukaemia (CML). Leukaemia is a cancer of white blood cells. These white cells 

usually help the body to fight infection. Chronic myeloid leukaemia is a form of leukaemia in which 
certain abnormal white cells (named myeloid cells) start growing out of control. 

 
In adult patients, Imatinib Teva B.V. is intended for use in the most advanced phase of the disease (blast 
crisis). In children and adolescents, Imatinib Teva B.V. can be used in different phases of the disease 
(chronic, accelerated phase and blast crisis). 
 
Imatinib Teva is also a treatment for adults and children for:  
- Philadelphia chromosome positive acute lymphoblastic leukaemia (Ph-positive ALL). Leukaemia 

is a cancer of white blood cells. These white cells usually help the body to fight infection. Acute 
lymphoblastic leukaemia is a form of leukaemia in which certain abnormal white cells (named 
lymphoblasts) start growing out of control. Imatinib Teva B.V. inhibits the growth of these cells.  

 
Imatinib Teva B.V. is also a treatment for adults for: 
- Myelodysplastic/myeloproliferative diseases (MDS/MPD). These are a group of blood diseases in 

which some blood cells start growing out of control. Imatinib Teva B.V. inhibits the growth of these 
cells in a certain subtype of these diseases.  

- Hypereosinophilic syndrome (HES) and/or chronic eosinophilic leukaemia (CEL). These are 
blood diseases in which some blood cells (named eosinophils) start growing out of control. Imatinib 
Teva B.V. inhibits the growth of these cells in a certain subtype of these diseases. 

- Gastrointestinal stromal tumours (GIST). GIST is a cancer of the stomach and bowels. It arises 
from uncontrolled cell growth of the supporting tissues of these organs. 

- Dermatofibrosarcoma protuberans (DFSP). DFSP is a cancer of the tissue beneath the skin in 
which some cells start growing out of control. Imatinib Teva B.V. inhibits the growth of these cells.

In the rest of this leaflet, we will use the abbreviations when talking about these diseases. 
 
If you have any questions about how Imatinib Teva B.V. works or why this medicine has been prescribed for 
you, ask your doctor.  
 
 
2. What you need to know before you take Imatinib Teva B.V. 
 
Imatinib Teva B.V. will only be prescribed to you by a doctor with experience in medicines to treat blood 
cancers or solid tumours.  
 
Follow all your doctor’s instructions carefully, even if they differ from the general information contained in 
this leaflet.  
 
Do not take Imatinib Teva B.V. 
- if you are allergic to imatinib or any of the other ingredients of this medicine (listed in section 6).  
 
If this applies to you, tell your doctor without taking Imatinib Teva B.V.  
 
If you think you may be allergic but are not sure, ask your doctor for advice.  
 
Warnings and precautions 
Talk to your doctor before taking Imatinib Teva B.V.:  
- if you have or have ever had a liver, kidney or heart problem.  
- if you are taking the medicine levothyroxine because your thyroid has been removed.  
- if you have ever had or might now have a hepatitis B infection. This is because Imatinib Teva B.V. 

could cause hepatitis B to become active again, which can be fatal in some cases. Patients will be 
carefully checked by their doctor for signs of this infection before treatment is started. 

 
If any of these apply to you, tell your doctor before taking Imatinib Teva B.V. 
 
During treatment with Imatinib Teva B.V., tell your doctor straight away if you put on weight very 
quickly. Imatinib Teva B.V. may cause your body to retain water (severe fluid retention).  
 
While you are taking Imatinib Teva B.V. your doctor will regularly check whether the medicine is working. 
You will also have blood tests and be weighed regularly.  
 
Children and adolescents  
Imatinib Teva B.V. is also a treatment for children with CML. There is no experience in children with CML 
below 2 years of age. There is limited experience in children with Ph-positive ALL and very limited 
experience in children with MDS/MPD, DFSP, GIST and HES/CEL. 
 
Some children and adolescents taking Imatinib Teva B.V. may have slower than normal growth. The doctor 
will monitor the growth at regular visits.  
 
Other medicines and Imatinib Teva B.V. 
Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines, 
including medicines obtained without a prescription (such as paracetamol) and including herbal medicines 
(such as St. John’s Wort). Some medicines can interfere with the effect of Imatinib Teva B.V. when taken 
together. They may increase or decrease the effect of Imatinib Teva B.V., either leading to increased side 
effects or making Imatinib Teva B.V. less effective. Imatinib Teva B.V. may do the same to some other 
medicines.  
 
Tell your doctor if you are using medicines that prevent the formation of blood clots.

3. How to take Imatinib Teva B.V. 
 
Your doctor has prescribed Imatinib Teva B.V. because you suffer from a serious condition. Imatinib Teva 
B.V. can help you to fight this condition.

not sure.  
 
Do not stop taking Imatinib Teva B.V. unless your doctor tells you to. If you are not able to take the 
medicine as your doctor prescribed or you feel you do not need it anymore, contact your doctor straight

skip the missed dose.
