1. NAME OF THE MEDICINAL PRODUCT 
 
Gazyvaro 1,000 mg concentrate for solution for infusion. 
 
 
2. QUALITATIVE AND QUANTITATIVE COMPOSITION 
 
One vial of 40 mL concentrate contains 1,000 mg obinutuzumab, corresponding to a concentration 
before dilution of 25 mg/mL.  
 
Obinutuzumab is a Type II humanised anti-CD20 monoclonal antibody of the IgG1 subclass derived 
by humanisation of the parental B-Ly1 mouse antibody and produced in the Chinese Hamster Ovary 
cell line by recombinant DNA technology. 
 
For the full list of excipients, see section 6.1. 
 
 
3. PHARMACEUTICAL FORM 
 
Concentrate for solution for infusion. 
 
Clear, colourless to slightly brownish liquid. 
 
 
4. CLINICAL PARTICULARS 
 
4.1 Therapeutic indications 
 
Chronic lymphocytic leukaemia (CLL) 
 
Gazyvaro in combination with chlorambucil is indicated for the treatment of adult patients with 
previously untreated CLL and with comorbidities making them unsuitable for full-dose fludarabine 
based therapy (see section 5.1). 
 
Follicular lymphoma (FL)  
 
Gazyvaro in combination with chemotherapy, followed by Gazyvaro maintenance therapy in patients 
achieving a response, is indicated for the treatment of patients with previously untreated advanced FL 
(see section 5.1) 
 
Gazyvaro in combination with bendamustine followed by Gazyvaro maintenance is indicated for the 
treatment of patients with FL who did not respond or who progressed during or up to 6 months after 
treatment with rituximab or a rituximab-containing regimen. 
 
4.2 Posology and method of administration 
 
Gazyvaro should be administered under the close supervision of an experienced physician and in an 
environment where full resuscitation facilities are immediately available. 
 
Posology 
 
Prophylaxis and premedication for tumour lysis syndrome (TLS) 
 
Patients with a high tumour burden and/or a high circulating lymphocyte count (> 25 x 109/L) and/or 
renal impairment (CrCl < 70 mL/min) are considered at risk of TLS and should receive prophylaxis. 
Prophylaxis should consist of adequate hydration and administration of uricostatics (e.g. allopurinol), 
or suitable alternative treatment such as urate oxidase (e.g. rasburicase), starting 12-24 hours prior to 



3 
 

start of Gazyvaro infusion as per standard practice (see section 4.4). Patients should continue to 
receive repeated prophylaxis prior to each subsequent infusion, if deemed appropriate. 
 
Prophylaxis and premedication for infusion related reactions (IRRs) 
 
Premedication to reduce the risk of IRRs is outlined in Table 1 (see also section 4.4). Corticosteroid 
premedication is recommended for patients with FL and mandatory for CLL patients in the first cycle 
(see Table 1). Premedication for subsequent infusions and other premedication should be administered 
as described below. 
 
Hypotension, as a symptom of IRRs, may occur during Gazyvaro intravenous infusions. Therefore, 
withholding of antihypertensive treatments should be considered for 12 hours prior to and throughout 
each Gazyvaro infusion and for the first hour after administration (see section 4.4).

Dose 
 
Chronic lymphocytic leukaemia (CLL, in combination with chlorambucil1) 
 
For patients with CLL the recommended dose of Gazyvaro in combination with chlorambucil is shown 
in Table 2. 
 
Cycle 1 
 
The recommended dose of Gazyvaro in combination with chlorambucil is 1,000 mg administered over 
Day 1 and Day 2, (or Day 1 continued), and on Day 8 and Day 15 of the first 28 day treatment cycle.  
 
Two infusion bags should be prepared for the infusion on Days 1 and 2 (100 mg for Day 1 and 900 mg 
for Day 2). If the first bag is completed without modifications of the infusion rate or interruptions, the 
second bag may be administered on the same day (no dose delay necessary, no repetition of 
premedication), provided that appropriate time, conditions and medical supervision are available 
throughout the infusion. If there are any modifications of the infusion rate or interruptions during the 
first 100 mg the second bag must be administered the following day.  
 
Cycles 2 – 6 
 
The recommended dose of Gazyvaro in combination with chlorambucil is 1,000 mg administered on 
Day 1 of each cycle.

Duration of treatment 
 
Six treatment cycles, each of 28 day duration. 
 
Delayed or missed doses 
 
If a planned dose of Gazyvaro is missed, it should be administered as soon as possible; do not wait 
until the next planned dose. The planned treatment interval for Gazyvaro should be maintained 
between doses.  
 
Follicular lymphoma  
 
For patients with FL, the recommended dose of Gazyvaro in combination with chemotherapy is shown 
in Table 3. 
 



5 
 

Patients with previously untreated follicular lymphoma  
 
Induction (in combination with chemotherapy2) 
Gazyvaro should be administered with chemotherapy as follows: 
 
• Six 28-day cycles in combination with bendamustine2 or, 
• Six 21-day cycles in combination with cyclophosphamide, doxorubicin, vincristine, 

prednisolone (CHOP), followed by 2 additional cycles of Gazyvaro alone or, 
• Eight 21-day cycles in combination with cyclophosphamide, vincristine, and 

prednisone/prednisolone/methylprednisolone(CVP).  
 

Maintenance  
 
Patients who achieve a complete or partial response to induction treatment with Gazyvaro in 
combination with chemotherapy (CHOP or CVP or bendamustine) should continue to receive 
Gazyvaro 1,000 mg as single agent maintenance therapy once every 2 months for 2 years or until 
disease progression (whichever occurs first). 
 
Patients with follicular lymphoma who did not respond or who progressed during or up to 6 months 
after treatment with rituximab or a rituximab-containing regimen  
 
Induction (in combination with bendamustine2) 
 
Gazyvaro should be administered in six 28-day cycles in combination with bendamustine2. 
 
Maintenance  
 
Patients who achieved a complete or partial response to induction treatment (i.e. the initial 6 treatment 
cycles) with Gazyvaro in combination with bendamustine or have stable disease should continue to 
receive Gazyvaro 1,000 mg as single agent maintenance therapy once every 2 months for 2 years or 
until disease progression (whichever occurs first).

Duration of treatment 
 
Induction treatment of approximately six months (six treatment cycles of Gazyvaro, each of 28 day 
duration when combined with bendamustine, or eight treatment cycles of Gazyvaro, each of 21 day 
duration when combined with CHOP or CVP) followed by maintenance once every 2 months for 2 
years or until disease progression (whichever occurs first). 
 
Delayed or missed doses  
If a planned dose of Gazyvaro is missed, it should be administered as soon as possible; do not omit it 
or wait until the next planned dose.  
If toxicity occurs before Cycle 1 Day 8 or Cycle 1 Day 15, requiring delay of treatment, these doses 
should be given after resolution of toxicity. In such instances, all subsequent visits and the start of 
Cycle 2 will be shifted to accommodate for the delay in Cycle 1.  
 
During maintenance, maintain the original dosing schedule for subsequent doses. 
 
Dose modifications during treatment (all indications) 
 
No dose reductions of Gazyvaro are recommended.  
 
For management of symptomatic adverse events (including IRRs), see paragraph below (Management 
of IRRs or section 4.4). 
 
Special populations 
 
Elderly  
 
No dose adjustment is required in elderly patients (see section 5.2). 
 
Renal impairment 
 
No dose adjustment is required in patients with mild to moderate renal impairment (creatinine 
clearance [CrCl] 30-89 mL/min) (see section 5.2). The safety and efficacy of Gazyvaro has not been 
established in patients with severe renal impairment (CrCl < 30 mL/min) (see sections 4.8 and 5.2). 
 
Hepatic impairment 
  
The safety and efficacy of Gazyvaro in patients with impaired hepatic function has not been 
established. No specific dose recommendations can be made. 
 
Paediatric population 
 
The safety and efficacy of Gazyvaro in children and adolescents aged below 18 years has not been 
established. No data are available. 
 
Method of administration 
 
Gazyvaro is for intravenous use. It should be given as an intravenous infusion through a dedicated line 
after dilution (see section 6.6). Gazyvaro infusions should not be administered as an intravenous push 
or bolus.  
 
For instructions on dilution of Gazyvaro before administration, see section 6.6. 
 
Instructions on the rate of infusion are shown in Tables 4-5.

Maintenance 
Every 2 months for 2 years or 

until disease progression 
(whichever occurs first)  

 
Management of IRRs (all indications) 
 
Management of IRRs may require temporary interruption, reduction in the rate of infusion, or 
treatment discontinuations of Gazyvaro as outlined below (see also section 4.4). 
 
• Grade 4 (life threatening): Infusion must be stopped and therapy must be permanently 

discontinued. 
• Grade 3 (severe): Infusion must be temporarily stopped and symptoms treated. Upon resolution 

of symptoms, the infusion can be restarted at no more than half the previous rate (the rate being 
used at the time that the IRR occurred) and, if the patient does not experience any IRR 
symptoms, the infusion rate escalation can resume at the increments and intervals as appropriate 
for the treatment dose (see Tables 4 and 5). For CLL patients receiving the Day 1 (Cycle 1) dose 
split over two days, the Day 1 infusion rate may be increased back up to 25 mg/hr after 1 hour, 
but not increased further.  
The infusion must be stopped and therapy permanently discontinued if the patient experiences a 
second occurrence of a Grade 3 IRR. 

• Grade 1-2 (mild to moderate): The infusion rate must be reduced and symptoms treated. 
Infusion can be continued upon resolution of symptoms and, if the patient does not experience 
any IRR symptoms, the infusion rate escalation can resume at the increments and intervals as 
appropriate for the treatment dose (see Tables 4 and 5). For CLL patients receiving the Day 1 
(Cycle 1) dose split over the two days, the Day 1 infusion rate may be increased back up to 
25 mg/hr after 1 hour, but not increased further.

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 
 
In order to improve the traceability of biological medicinal products, the trade name and batch number 
of the administered product should be clearly recorded (or stated) in the patient file.  
 
Based on a subgroup analysis in previously untreated follicular lymphoma, the efficacy in FLIPI low 
risk (0-1) patients is currently inconclusive (see section 5.1). A therapy choice for these patients 
should carefully consider the overall safety profile of Gazyvaro plus chemotherapy and the  
patient-specific situation. 
 
Infusion related reactions  
 
The most frequently observed adverse drug reactions (ADRs) in patients receiving Gazyvaro were 
IRRs, which occurred predominantly during infusion of the first 1,000 mg. IRRs may be related to 
cytokine release syndrome which has also been reported in Gazyvaro treated patients. In CLL patients 
who received the combined measures for prevention of IRRs (adequate corticosteroid, oral 
analgesic/anti-histamine, omission of antihypertensive medicine in the morning of the first infusion, 
and the Cycle 1 Day 1 dose administered over 2 days) as described in section 4.2, a decreased 
incidence of IRRs of all Grades was observed. The rates of Grade 3-4 IRRs (which were based on a 
relatively small number of patients) were similar before and after mitigation measures were 
implemented. Mitigation measures to reduce IRRs should be followed (see section 4.2). The incidence 
and severity of infusion related symptoms decreased substantially after the first 1,000 mg was infused, 
with most patients having no IRRs during subsequent administrations of Gazyvaro (see section 4.8). 
 
In the majority of patients, irrespective of indication, IRRs were mild to moderate and could be 
managed by the slowing or temporary halting of the first infusion, but severe and life-threatening IRRs 
requiring symptomatic treatment have also been reported. IRRs may be clinically indistinguishable 
from immunoglobulin E (IgE) mediated allergic reactions (e.g. anaphylaxis). Patients with a high 
tumour burden and/or high circulating lymphocyte count in CLL [> 25 x 109/L] may be at increased 
risk of severe IRRs. Patients with renal impairment (CrCl < 50 mL/min) and patients with both 
Cumulative Illness Rating Scale (CIRS) > 6 and CrCl < 70 mL/min are more at risk of IRRs, including 
severe IRRs (see section 4.8). For management of IRRs see section 4.2 Posology and method of 
administration. 
 
Patients must not receive further Gazyvaro infusions if they experience:  
• acute life-threatening respiratory symptoms,  
• a Grade 4 (i.e. life threatening) IRR or,  
• a second occurrence of a Grade 3 (prolonged/recurrent) IRR (after resuming the first infusion or 

during a subsequent infusion). 
 
Patients who have pre-existing cardiac or pulmonary conditions should be monitored carefully 
throughout the infusion and the post-infusion period. Hypotension may occur during Gazyvaro 
intravenous infusions. Therefore, withholding of antihypertensive treatments should be considered for 
12 hours prior to and throughout each Gazyvaro infusion and for the first hour after administration. 
Patients at acute risk of hypertensive crisis should be evaluated for the benefits and risks of 
withholding their anti-hypertensive medicine. 
 
Hypersensitivity reactions  
 
Hypersensitivity reactions with immediate (e.g.  anaphylaxis) and delayed onset (e.g. serum sickness) 
have been reported in patients treated with Gazyvaro. Hypersensitivity may be difficult to clinically 
distinguish from IRRs. Hypersensitivity symptoms can occur after previous exposure and very rarely 
with the first infusion. If a hypersensitivity reaction is suspected during or after an infusion, the 



10 
 

infusion must be stopped and treatment permanently discontinued. Patients with known 
hypersensitivity to obinutuzumab must not be treated (see section 4.3). 
 
Tumour lysis syndrome (TLS) 
 
TLS has been reported with Gazyvaro. Patients who are considered to be at risk of TLS (e.g. patients 
with a high tumour burden and/or a high circulating lymphocyte count [> 25 x 109/L] and/or renal 
impairment [CrCl < 70 mL/min]) should receive prophylaxis. Prophylaxis should consist of adequate 
hydration and administration of uricostatics (e.g. allopurinol), or a suitable alternative such as a urate 
oxidate (e.g. rasburicase) starting 12-24 hours prior to the infusion of Gazyvaro as per standard 
practice (see section 4.2). All patients considered at risk should be carefully monitored during the 
initial days of treatment with a special focus on renal function, potassium, and uric acid values. Any 
additional guidelines according to standard practice should be followed. For treatment of TLS, correct 
electrolyte abnormalities, monitor renal function and fluid balance, and administer supportive care, 
including dialysis as indicated. 
 
Neutropenia  
 
Severe and life-threatening neutropenia including febrile neutropenia has been reported during 
treatment with Gazyvaro. Patients who experience neutropenia should be closely monitored with 
regular laboratory tests until resolution. If treatment is necessary it should be administered in 
accordance with local guidelines and the administration of granulocyte-colony stimulating factors  
(G-CSF) should be considered. Any signs of concomitant infection should be treated as appropriate. 
Dose delays should be considered in case of severe or life-threatening neutropenia. It is strongly 
recommended that patients with severe neutropenia lasting more than 1 week receive antimicrobial 
prophylaxis throughout the treatment period until resolution to Grade 1 or 2. Antiviral and antifungal 
prophylaxis should also be considered (see section 4.2). Late onset neutropenia (occurring >28 days 
after the end of treatment) or prolonged neutropenia (lasting more than 28 days after treatment has 
been completed/stopped) may occur. Patients with renal impairment (CrCl < 50 mL/min) are more at 
risk of neutropenia (see section 4.8).  
 
Thrombocytopenia 
 
Severe and life-threatening thrombocytopenia including acute thrombocytopenia (occurring within 
24 hours after the infusion) has been observed during treatment with Gazyvaro. Patients with renal 
impairment (CrCl < 50 mL/min) are more at risk of thrombocytopenia (see section 4.8). Fatal 
haemorrhagic events have also been reported in Cycle 1 in patients treated with Gazyvaro. A clear 
relationship between thrombocytopenia and haemorrhagic events has not been established.  
 
Patients should be closely monitored for thrombocytopenia, especially during the first cycle; regular 
laboratory tests should be performed until the event resolves, and dose delays should be considered in 
case of severe or life-threatening thrombocytopenia. Transfusion of blood products (i.e. platelet 
transfusion) according to institutional practice is at the discretion of the treating physician. Use of any 
concomitant therapies which could possibly worsen thrombocytopenia-related events, such as platelet 
inhibitors and anticoagulants, should also be taken into consideration, especially during the first cycle. 
 
Worsening of pre-existing cardiac conditions 
 
In patients with underlying cardiac disease, arrhythmias (such as atrial fibrillation and 
tachyarrhythmia), angina pectoris, acute coronary syndrome, myocardial infarction and heart failure 
have occurred when treated with Gazyvaro (see section 4.8). These events may occur as part of an IRR 
and can be fatal. Therefore patients with a history of cardiac disease should be monitored closely. In 
addition these patients should be hydrated with caution in order to prevent a potential fluid overload. 
 



11 
 

Infections 
 
Gazyvaro should not be administered in the presence of an active infection and caution should be 
exercised when considering the use of Gazyvaro in patients with a history of recurring or chronic 
infections.  Serious bacterial, fungal, and new or reactivated viral infections can occur during and 
following the completion of Gazyvaro therapy. Fatal infections have been reported.  
 
Patients (CLL) with both CIRS > 6 and CrCl < 70 mL/min are more at risk of infections, including 
severe infections (see section 4.8). In the follicular lymphoma studies, a high incidence of infections 
was observed in all phases of the studies, including follow-up, with the highest incidence seen in the 
maintenance phase. During the follow-up phase, Grade 3-5 infections are observed more in patients 
who received Gazyvaro plus bendamustine in the induction phase. 
 
Hepatitis B reactivation  
 
Hepatitis B virus (HBV) reactivation, in some cases resulting in fulminant hepatitis, hepatic failure 
and death, can occur in patients treated with anti-CD20 antibodies including Gazyvaro (see section 
4.8). HBVscreening should be performed in all patients before initiation of treatment with Gazyvaro. 
At a minimum this should include hepatitis B surface antigen (HBsAg) status and hepatitis B core 
antibody (HBcAb) status. These can be complemented with other appropriate markers as per local 
guidelines. Patients with active hepatitis B disease should not be treated with Gazyvaro. Patients with 
positive hepatitis B serology should consult liver disease experts before start of treatment and should 
be monitored and managed following local medical standards to prevent hepatitis reactivation.  
 
Progressive multifocal leukoencephalopathy (PML) 
 
Progressive multifocal leukoencephalopathy (PML) has been reported in patients treated with 
Gazyvaro (see section 4.8). The diagnosis of PML should be considered in any patient presenting with 
new-onset or changes to pre-existing neurologic manifestations. The symptoms of PML are 
nonspecific and can vary depending on the affected region of the brain. Motor symptoms with 
corticospinal tract findings (e.g. muscular weakness, paralysis and sensory disturbances), sensory 
abnormalities, cerebellar symptoms, and visual field defects are common. Some signs/symptoms 
regarded as “cortical” (e.g. aphasia or visual-spatial disorientation) may occur. Evaluation of PML 
includes, but is not limited to, consultation with a neurologist, brain magnetic resonance imaging 
(MRI), and lumbar puncture (cerebrospinal fluid testing for John Cunningham viral DNA). Therapy 
with Gazyvaro should be withheld during the investigation of potential PML and permanently 
discontinued in case of confirmed PML. Discontinuation or reduction of any concomitant 
chemotherapy or immunosuppressive therapy should also be considered. The patient should be 
referred to a neurologist for the evaluation and treatment of PML. 
 
Immunisation 
 
The safety of immunisation with live or attenuated viral vaccines following Gazyvaro therapy has not 
been studied and vaccination with live virus vaccines is not recommended during treatment and until 
B-cell recovery.  
 
Exposure in utero to obinutuzumab and vaccination of infants with live virus vaccines 
 
Due to the potential depletion of B-cells in infants of mothers who have been exposed to Gazyvaro 
during pregnancy, infants should be monitored for B-cell depletion and vaccinations with live virus 
vaccines should be postponed until the infant’s B-cell count has recovered.  The safety and timing of 
vaccination should be discussed with the infant’s physician (see section 4.6).

4.5 Interaction with other medicinal products and other forms of interaction 
 
No formal drug-drug interaction studies have been performed, although limited drug-drug interaction 
sub-studies have been undertaken for Gazyvaro with bendamustine, CHOP, fludarabine and 
cyclophosphamide (FC), and chlorambucil.  
 
A risk for interactions with other concomitantly used medicinal products cannot be excluded. 
 
Pharmacokinetic interactions 
 
Obinutuzumab is not a substrate, inhibitor, or inducer of cytochrome P450 (CYP450), uridine 
diphosphate glucuronyltransferase (UGT) enzymes and transporters such as P-glycoprotein. Therefore, 
no pharmacokinetic interaction is expected with medicinal products known to be metabolised by these 
enzyme systems. 
 
Co-administration with Gazyvaro had no effect on the pharmacokinetics of bendamustine, FC, 
chlorambucil or the individual components of CHOP. In addition, there were no apparent effects of 
bendamustine, FC, chlorambucil or CHOP on the pharmacokinetics of Gazyvaro. 
 
Pharmacodynamic interactions 
 
Vaccination with live virus vaccines is not recommended during treatment and until B-cell recovery 
because of the immunosuppressive effect of obinutuzumab (see section 4.4). 
 
The combination of obinutuzumab with chlorambucil, bendamustine, CHOP or CVP may increase the 
risk of neutropenia (see section 4.4). 
 
4.6 Fertility, pregnancy and lactation 
 
Women of childbearing potential 
 
Women of childbearing potential must use effective contraception during and for 18 months after 
treatment with Gazyvaro. 
 
Pregnancy 
 
A reproduction study in cynomolgus monkeys showed no evidence of embryofoetal toxicity or 
teratogenic effects but resulted in a complete depletion of B-lymphocytes in offspring. B-cell counts 
returned to normal levels in the offspring, and immunologic function was restored within 6 months of 
birth. Serum concentrations of obinutuzumab in offspring were similar to those in the mothers on 
day 28 post-partum, whereas concentrations in milk on the same day were very low, suggesting that 
obinutuzumab crosses the placenta (see section 5.3). There are no data from the use of obinutuzumab 
in pregnant women. Gazyvaro should not be administered to pregnant women unless the possible 
benefit outweighs the potential risk. 
 
In case of exposure during pregnancy, depletion of B-cells may be expected in infants due to the 
pharmacological properties of the product. Postponing vaccination with live vaccines should be 
considered for infants born to mothers who have been exposed to Gazyvaro during pregnancy until the 
infant’s B-cell levels are within normal ranges (see section 4.4). 
 
Breast-feeding 
 
Animal studies have shown secretion of obinutuzumab in breast milk (see section 5.3). 
 
Since human immunoglobulin G (IgG) is secreted in human milk and the potential for absorption and 
harm to the infant is unknown, women should be advised to discontinue breast-feeding during 
Gazyvaro therapy and for 18 months after the last dose of Gazyvaro.

Fertility 
 
No specific studies in animals have been performed to evaluate the effect of obinutuzumab on fertility. 
No adverse effects on male and female reproductive organs were observed in repeat-dose toxicity 
studies in cynomolgus monkeys (see section 5.3). 
 
4.7 Effects on ability to drive and use machines 
 
Gazyvaro has no or negligible influence on the ability to drive and use machines. IRRs are very 
common during the first infusion of Gazyvaro, and patients experiencing infusion related symptoms 
should be advised not to drive or use machines until symptoms abate. 
 
4.8 Undesirable effects 
 
Summary of the safety profile 
 
The adverse drug reactions (ADRs) described in this section were identified during induction, 
maintenance and follow up for indolent Non-Hodgkin lymphoma (iNHL) including FL; treatment and 
follow up for CLL in the three pivotal clinical studies: 
• BO21004/CLL11 (N=781): Patients with previously untreated CLL 
• BO21223/GALLIUM (N=1390): Patients with previously untreated iNHL (86% of the patients 

had FL) 
• GAO4753g/GADOLIN (N=409): Patients with iNHL (81% of the patients had FL) who had no 

response to or who progressed during or up to 6 months after treatment with rituximab or a 
rituximab-containing regimen.  

 
These trials investigated Gazyvaro in combination with chlorambucil for CLL and with bendamustine, 
CHOP or CVP followed by Gazyvaro maintenance therapy for iNHL. The studies 
BO21223/GALLIUM and GAO4753g/GADOLIN enrolled patients with iNHL including FL. 
Therefore, in order to provide the most comprehensive safety information, the analysis of ADRs 
presented in the following has been performed on the entire study population (i.e. iNHL). 
 
Table 6 summarises the ADRs of the pivotal studies (BO21004/CLL11, BO21223/GALLIUM 
GAO4753g/GADOLIN) that occurred at a higher incidence (difference of ≥ 2%) compared to the 
relevant comparator arm in at least one pivotal study in: 
• Patients with CLL receiving Gazyvaro plus chlorambucil compared with chlorambucil alone or 

rituximab plus chlorambucil (study BO21004/CLL11)  
• Patients with previously untreated iNHL receiving Gazyvaro plus chemotherapy (bendamustine, 

CHOP, CVP) followed by Gazyvaro maintenance in patients achieving a response, compared to 
rituximab plus chemotherapy followed by rituximab maintenance in patients achieving a 
response (study BO21223/GALLIUM) 

• Patients with iNHL who had no response to or who progressed during or up to 6 months after 
treatment with rituximab or a rituximab-containing regimen receiving Gazyvaro plus 
bendamustine, followed by Gazyvaro maintenance in some patients, compared to bendamustine 
alone (study GAO4753g/GADOLIN)  

The incidences presented in Table 6 (all grades and Grades 3-5) are the highest incidence of that ADR 
reported from any of the three studies.  
 
Frequencies are defined as 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) and very rare (< 1/10,000). Within each frequency 
grouping, adverse reactions are presented in order of decreasing seriousness.

In study GAO4753g/GADOLIN, patients in the bendamustine arm received 6 months of induction 
treatment only, whereas after the induction period, patients in the Gazyvaro plus bendamustine arm 
continued with Gazyvaro maintenance treatment. 
 
During the maintenance period in study GAO4753g/GADOLIN, the most common adverse reactions 
were cough (20%), neutropenia (13%), upper respiratory infections (12%),  sinusitis (10%), diarrhoea 
(10%), bronchitis (10%), nausea (9%), fatigue (9%), IRRs (8%), urinary tract infections (7%), 
nasopharyngitis (7%), pyrexia (7%), arthralgia (6%), vomiting (6%), rash (6%), pneumonia (5%), 
dyspnea (5%) and pain in extremity (5%). The most common Grade 3-5 adverse reactions were 
neutropenia (10%), febrile neutropenia (2%) and anaemia,  thrombocytopenia, pneumonia, sepsis, 
upper respiratory tract infection, and urinary tract infection (all at 1%).  
 
The profile of adverse reactions in patients with FL was consistent with the overall iNHL population 
in both studies. 
 
Description of selected adverse reactions 
 
The incidences presented in the following sections if referring to iNHL are the highest incidence of 
that ADR reported from either pivotal study (BO21223/GALLIUM, GAO4753g/GADOLIN). 
 
Infusion related reactions  
 
Most frequently reported (≥ 5%) symptoms associated with an IRR were nausea, vomiting, diarrhoea, 
headache, dizziness, fatigue, chills, pyrexia, hypotension, flushing, hypertension, tachycardia, 
dyspnoea, and chest discomfort. Respiratory symptoms such as bronchospasm, larynx and throat 
irritation, wheezing, laryngeal oedema and cardiac symptoms such as atrial fibrillation have also been 
reported (see section 4.4). 



16 
 

 
Chronic Lymphocytic Leukaemia  
 
The incidence of IRRs was higher in the Gazyvaro plus chlorambucil arm compared to the rituximab 
plus chlorambucil arm. The incidence of IRRs was 66% with the infusion of the first 1,000 mg of 
Gazyvaro (20% of patients experiencing a Grade 3-4 IRR). Overall, 7% of patients experienced an 
IRR leading to discontinuation of Gazyvaro. The incidence of IRRs with subsequent infusions was 3% 
with the second 1,000 mg dose and 1% thereafter. No Grade 3-5 IRRs were reported beyond the first 
1,000 mg infusions of Cycle 1.  
 
In patients who received the recommended measures for prevention of IRRs as described in section 
4.2, a decreased incidence of IRRs of all Grades was observed. The rates of Grade 3-4 IRRs (which 
occurred in relatively few patients) were similar before and after mitigation measures were 
implemented. 
 
Indolent Non-Hodgkin Lymphoma including Follicular Lymphoma  
 
Grade 3-4 IRRs occurred in 12% of patients. In Cycle 1, the overall incidence of IRRs was higher in 
patients receiving Gazyvaro plus chemotherapy compared to patients in the comparator arm. In 
patients receiving Gazyvaro plus chemotherapy, the incidence of IRRs was highest on Day 1 and 
gradually decreased with subsequent infusions. This decreasing trend continued during maintenance 
therapy with Gazyvaro alone. Beyond Cycle 1 the incidence of IRRs in subsequent infusions was 
comparable between the Gazyvaro and the relevant comparator arms. Overall, 4% of patients 
experienced an infusion related reaction leading to discontinuation of Gazyvaro. 
 
Neutropenia and infections 
 
Chronic Lymphocytic Leukaemia 
 
The incidence of neutropenia was higher in the Gazyvaro plus chlorambucil arm (41%) compared to 
the rituximab plus chlorambucil arm with the neutropenia resolving spontaneously or with use of 
granulocyte-colony stimulating factors. The incidence of infection was 38% in the Gazyvaro plus 
chlorambucil arm and 37% in the rituximab plus chlorambucil arm (with Grade 3-5 events reported in 
12% and 14%, respectively and fatal events reported in < 1% in both treatment arms). Cases of 
prolonged neutropenia (2% in the Gazyvaro plus chlorambucil arm and 4% in the rituximab plus 
chlorambucil arm) and late onset neutropenia (16% in the Gazyvaro plus chlorambucil arm and 12% 
in the rituximab plus chlorambucil arm) were also reported (see section 4.4). 
 
Indolent Non-Hodgkin Lymphoma including Follicular Lymphoma  
 
In the Gazyvaro plus chemotherapy arm, the incidence of Grade 1-4 neutropenia (50%) was higher 
relative to the comparator arm with an increased risk during the induction period. The incidence of 
prolonged neutropenia and late onset neutropenia was 3% and 8%, respectively. The incidence of 
infection was 81% in the Gazyvaro plus chemotherapy arm (with Grade 3-5 events reported in 22% of 
patients and fatal events reported in 3% of patients). Patients who received G-CSF prophylaxis had a 
lower rate of Grade 3-5 infections (see section 4.4). 
 
Thrombocytopenia and haemorrhagic events 
 
Chronic Lymphocytic Leukaemia 
 
The incidence of thrombocytopenia was higher in the Gazyvaro plus chlorambucil arm compared to 
the rituximab plus chlorambucil arm (16% vs. 7%) especially during the first cycle. Four percent of 
patients treated with Gazyvaro plus chlorambucil experienced acute thrombocytopenia (occurring 
within 24 hours after the Gazyvaro infusion) (see section 4.4). The overall incidence of haemorrhagic 
events was similar in the Gazyvaro treated arm and in the rituximab treated arm. The number of fatal 
haemorrhagic events was balanced between the treatment arms; however, all of the events in patients 



17 
 

treated with Gazyvaro were reported in Cycle 1. No Grade 5 events of thrombocytopenia were 
reported. A clear relationship between thrombocytopenia and haemorrhagic events has not been 
established. 
 
Indolent Non-Hodgkin Lymphoma including Follicular Lymphoma  
 
The incidence of thrombocytopenia was 15%. Thrombocytopenia occurred more frequently in Cycle 1 
in the Gazyvaro plus chemotherapy arm. Thrombocytopenia occurring during or 24 hours from end of 
infusion (acute thrombocytopenia) was more frequently observed in patients in the Gazyvaro plus 
chemotherapy arm than in the comparator arm. The incidence of haemorrhagic events was similar 
across all treatment arms. Haemorrhagic events and Grade 3-5 haemorrhagic events occurred in 12% 
and 4% of patients, respectively. While fatal haemorrhagic events occurred in less than 1% of patients; 
none of the fatal adverse events occurred in Cycle 1. 
 
Special populations 
 
Elderly 
 
Chronic Lymphocytic Leukaemia 
 
In the pivotal BO21004/CLL11 study, 46% (156 out of 336) of patients with CLL treated with 
Gazyvaro plus chlorambucil were 75 years or older (median age was 74 years). These patients 
experienced more serious adverse events and adverse events leading to death than those patients 
< 75 years of age. 
 
Indolent Non Hodgkin Lymphoma including Follicular Lymphoma 
 
In the pivotal studies (BO21223/GALLIUM, GAO4753g/GADOLIN) in iNHL, patients 65 years or 
older experienced more serious adverse events and adverse events leading to withdrawal or death than 
patients < 65 years of age. 
 
Renal impairment 
 
Chronic Lymphocytic Leukaemia 
 
In the pivotal BO21004/CLL11 study, 27% (90 out of 336) of patients treated with Gazyvaro plus 
chlorambucil had moderate renal impairment (CrCl < 50 mL/min). These patients experienced more 
serious adverse events and adverse events leading to death than patients with a CrCl ≥ 50 mL/min 
(see section 4.2, 4.4 and 5.2). Patients with a CrCl < 30 mL/min were excluded from the study 
(see section 5.1). 
 
Indolent Non Hodgkin Lymphoma including Follicular Lymphoma 
 
In the pivotal studies (BO21223/GALLIUM, GAO4753g/GADOLIN) in iNHL, 5% (35 out of 698) 
and 7% (14 out of 204) of patients treated with Gazyvaro, respectively, had moderate renal 
impairment (CrCL < 50 mL/min). These patients experienced more serious adverse events, G rade 3 to 
5 adverse events  and adverse events leading to treatment withdrawal (patients in BO21223 only) than 
patients with a CrCl ≥ 50 mL/min (see section 4.2 and 5.2). Patients with a CrCl < 40 mL/min were 
excluded from the studies (see section 5.1). 
 
Additional safety information from clinical studies experience 
 
Progressive multifocal leukoencephalopathy  
PML has been reported in patients treated with Gazyvaro (see section 4.4).  
 



18 
 

Hepatitis B reactivation  
 
Cases of hepatitis B reactivation have been reported in patients treated with Gazyvaro 
(see section 4.4). 
 
Gastro-Intestinal Perforation  
 
Cases of gastro-intestinal perforation have been reported in patients receiving Gazyvaro, mainly in 
iNHL. In the pivotal studies in iNHL up to 1% of patients experienced gastrointestinal perforation. 
 
Worsening of pre-existing cardiac conditions 
 
Cases of arrhythmias (such as atrial fibrillation and tachyarrhythmia), angina pectoris, acute coronary 
syndrome, myocardial infarction and heart failure have occurred when treated with Gazyvaro (see 
section 4.4). These events may occur as part of an IRR and can be fatal. 
 
Laboratory abnormalities 
 
Transient elevation in liver enzymes (aspartate aminotransferase [AST], alanine aminotransferase 
[ALT], alkaline phosphatase) has been observed shortly after the first infusion of Gazyvaro.  
 
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 
 
No experience with overdose is available from human clinical studies. In clinical studies with 
Gazyvaro, doses ranging from 50 mg up to and including 2,000 mg per infusion have been 
administered. The incidence and intensity of adverse reactions reported in these studies did not appear 
to be dose dependent. 
 
Patients who experience overdose should have immediate interruption or reduction of their infusion 
and be closely supervised. Consideration should be given to the need for regular monitoring of blood 
cell count and for increased risk of infections while patients are B-cell depleted. 
 
 
5. PHARMACOLOGICAL PROPERTIES 
 
5.1 Pharmacodynamic properties 
 
Pharmacotherapeutic group: Antineoplastic agents, monoclonal antibodies, ATC code: L01XC15 
 
Mechanism of action 
 
Obinutuzumab is a recombinant monoclonal humanised and glycoengineered Type II anti-CD20 
antibody of the IgG1 isotype. It specifically targets the extracellular loop of the CD20 transmembrane 
antigen on the surface of non-malignant and malignant pre-B and mature B-lymphocytes, but not on 
haematopoietic stem cells, pro-B-cells, normal plasma cells or other normal tissue. Glycoengineering 
of the Fc part of obinutuzumab results in higher affinity for FcɣRIII receptors on immune effector 
cells such as natural killer (NK) cells, macrophages and monocytes as compared to  
non-glycoengineered antibodies. 
 

https://www.ema.europa.eu/documents/template-form/appendix-v-adverse-drug-reaction-reporting-details_en.doc


19 
 

In nonclinical studies, obinutuzumab induces direct cell death and mediates antibody dependent 
cellular cytotoxicity (ADCC) and antibody dependent cellular phagocytosis (ADCP) through 
recruitment of FcɣRIII positive immune effector cells. In addition, in vivo, obinutuzumab mediates a 
low degree of complement dependent cytotoxicity (CDC). Compared to Type I antibodies, 
obinutuzumab, a Type II antibody, is characterised by an enhanced direct cell death induction with a 
concomitant reduction in CDC at an equivalent dose. Obinutuzumab, as a glycoengineered antibody, is 
characterised by enhanced ADCC and ADCP compared to non-glycoengineered antibodies at an 
equivalent dose. In animal models obinutuzumab mediates potent B-cell depletion and antitumour 
efficacy.  
 
In the pivotal clinical study in patients with CLL (BO21004/CLL11), 91% (40 out of 44) of evaluable 
patients treated with Gazyvaro were B-cell depleted (defined as CD19+ B-cell counts < 0.07 x 109/L) 
at the end of treatment period and remained depleted during the first 6 months of follow up. Recovery 
of B-cells was observed within 12-18 months of follow up in 35% (14 out of 40) of patients without 
progressive disease and 13% (5 out of 40) with progressive disease.  
 
In the pivotal clinical study in patients with iNHL (GAO4753/GADOLIN), 97% (171 out of 176) of 
evaluable patients treated with Gazyvaro were B-cell depleted at the end of the treatment period, and 
97% (61 out of 63) remained depleted for more than 6 months from the last dose. Recovery of B-cells 
was observed within 12-18 months of follow-up in 11% (5 out of 46) of evaluable patients. 
 
Clinical efficacy and safety 
 
Chronic Lymphocytic Leukaemia 
 
A Phase III international, multicentre, open label, randomised, two-stage, three-arm clinical study 
(BO21004/CLL11) investigating the efficacy and safety of Gazyvaro plus chlorambucil (GClb) 
compared to rituximab plus chlorambucil (RClb) or chlorambucil (Clb) alone was conducted in 
patients with previously untreated CLL with comorbidities.  
 
Prior to enrolment, patients had to have documented CD20+ CLL, and one or both of the following 
measures of coexisting medical conditions: comorbidity score (CIRS) of greater than 6 or reduced 
renal function as measured by CrCl < 70 mL/min. Patients with inadequate liver function (National 
Cancer Institute – Common Terminology Criteria for Adverse Events Grade 3 liver function tests 
(AST, ALT > 5 x ULN for > 2 weeks; bilirubin > 3 x ULN) and renal function (CrCl < 30 mL/min) 
were excluded. Patients with one or more individual organ/system impairment score of 4 as assessed 
by the CIRS definition, excluding eyes, ears, nose, throat and larynx organ system, were excluded. 
 
A total of 781 patients were randomised 2:2:1 to receive Gazyvaro plus chlorambucil, rituximab plus 
chlorambucil or chlorambucil alone. Stage 1a compared Gazyvaro plus chlorambucil to chlorambucil 
alone in 356 patients and Stage 2 compared Gazyvaro plus chlorambucil to rituximab plus 
chlorambucil in 663 patients.  
 
In the majority of patients, Gazyvaro was given intravenously as a 1,000 mg initial dose administered 
on Day 1, Day 8 and Day 15 of the first treatment cycle. In order to reduce the rate of infusion related 
reactions in patients, an amendment was implemented and 140 patients received the first Gazyvaro 
dose administered over 2 days (Day 1 [100 mg] and Day 2 [900 mg]) (see section 4.2 and 4.4). For 
each subsequent treatment cycle (Cycles 2 to 6), patients received Gazyvaro 1,000 mg on Day 1 only. 
Chlorambucil was given orally at 0.5 mg/kg body weight on Day 1 and Day 15 of all treatment cycles 
(1 to 6). 
 
The demographics data and baseline characteristics were well balanced between the treatment arms. 
The majority of patients were Caucasian (95%) and male (61%). The median age was 73 years, with 
44% being 75 years or older. At baseline, 22% of patients had Binet Stage A, 42% had Binet Stage B 
and 36% had Binet Stage C. 
 



20 
 

The median comorbidity score was 8 and 76% of the patients enrolled had a comorbidity score 
above 6. The median estimated CrCl was 62 mL/min and 66% of all patients had a CrCl < 70 mL/min. 
Forty-two percent of patients enrolled had both a CrCl < 70 mL/min and a comorbidity score of > 6. 
Thirty-four percent of patients were enrolled on comorbidity score alone, and 23% of patients were 
enrolled with only impaired renal function.  
 
The most frequently reported coexisting medical conditions (using a cut off of 30% or higher), in the 
MedDRA body systems are: Vascular disorders (73%), Cardiac disorders (46%), Gastrointestinal 
disorders (38%), Metabolism and nutrition disorders (40%), Renal and urinary disorders (38%), 
Musculoskeletal and connective tissue disorders (33%). 
 
Efficacy results for patients with previously untreated CLL are summarised in Table 7. Kaplan-Meier 
curves for progression-free survival (PFS) and Overall Survival (OS) are shown in Figures 1-4.

Results of subgroup analyses 
 
Results of the progression free survival (PFS) subgroup analysis (i.e. sex, age, Binet stages, CrCl, 
CIRS score, beta2-microglobulin, IGVH status, chromosomal abnormalities, lymphocyte count at 
baseline) were consistent with the results seen in the overall Intent-to-Treat population. The risk of 
disease progression or death was reduced in the GClb arm compared to the RClb arm and Clb arm in 
all subgroups except in the subgroup of patients with deletion 17p. In the small subgroup of patients 
with deletion 17p, only a positive trend was observed compared to Clb (HR=0.42, p=0.0892); no 
benefit was observed compared to RClb. For subgroups, reduction of the risk of disease progression or 
death ranged from 92% to 58% for GClb versus Clb and 72% to 29% for GClb versus RClb.

Quality of life 
 
In the QLQC30 and QLQ-CLL-16 questionnaires conducted during the treatment period, no 
substantial difference in any of the subscales was observed. Data during follow up, especially for the 
chlorambucil alone arm, is limited. However, no notable differences in quality of life during follow up 
have been identified to date. 
 



24 
 

Health-related quality of life assessments, specific to fatigue through treatment period, show no 
statistically significant difference suggesting that the addition of Gazyvaro to a chlorambucil regimen 
does not increase the experience of fatigue for patients. 
 
Follicular lymphoma 
 
Previously untreated follicular lymphoma (study BO21223/GALLIUM)  
 
In a phase III, open label, multicentre, randomised clinical study (BO21223/GALLIUM), 
1202 patients with previously untreated Grade 1-3a advanced (stage II bulky disease, stage III/IV) FL 
were evaluated. Patients with FL Grade 3b were excluded from the study. Patients were randomised to 
1:1 to receive either Gazyvaro (n=601 patients) or rituximab (n=601 patients) in combination with 
chemotherapy (bendamustine, CHOP or CVP), followed by Gazyvaro or rituximab maintenance in 
patients achieving a complete or partial response.  
 
Gazyvaro was given by intravenous infusion as a dose of 1,000 mg on Days 1, 8 and 15 of Cycle 1, on 
Day 1 of subsequent cycles. In total, six cycles of Gazyvaro (every 28 days) were given in 
combination with six cycles of bendamustine, and a total of eight cycles of Gazyvaro (every 21 days) 
were given in combination with six cycles of CHOP or eight cycles of CVP. Gazyvaro was 
administered prior to chemotherapy. Bendamustine was given intravenously on Days 1 and 2 for all 
treatment cycles (Cycles 1-6) at 90 mg/m2/day when given in combination with Gazyvaro. Standard 
dosing of CHOP and CVP was given. Following Cycles 6-8, in combination with chemotherapy, 
responding patients received Gazyvaro maintenance therapy every 2 months until disease progression 
or for up to 2 years.  
 
The demographic data and baseline characteristics of the patient population were well balanced 
between the treatment arms; median age was 59 years, 81% were Caucasian, 53% were female, 79% 
had a FLIPI score of ≥ 2 and 7% had Stage II (bulky), 35% had Stage III and 57% had Stage IV 
disease, 44% had bulky disease (> 7 cm), 34% had at least one B-symptom at baseline and 97% had an 
ECOG performance status of 0-1 at baseline. Fifty-seven percent received bendamustine, 33% 
received CHOP, and 10% received CVP chemotherapy.  
 
Efficacy results for patients with previously untreated FL are summarised in Table 8. Kaplan-Meier 
curves for progression-free survival (PFS) are shown in Figure 5.

Results of subgroup analyses 
 
Results of subgroup analyses (not adjusted for multiplicity) were, in general, consistent with the 
results seen in the FL population, supporting the robustness of the overall result. The subgroups 
evaluated included IPI, FLIPI, Bulky Disease, B Symptoms at baseline, Ann Arbor Stage and ECOG 
at baseline. In patients with FLIPI score 0-1 (low risk), no difference between Gazyvaro plus 
chemotherapy and rituximab plus chemotherapy was observed (INV-assessed PFS HR 1.17 (95%CI 
0.63;2.19, 40 PFS events).  This subgroup  comprised 21% (253/1202) of the FL ITT  population and  
experienced 16.3% (40/245) of the PFS events. In addition, exploratory subgroup analyses of PFS 
across chemotherapy regimens (bendamustine, CHOP and CVP) were consistent with the results seen 
in the Gazyvaro plus chemotherapy population. The observed HRs by chemotherapy subgroup were as 
follows; CHOP (n = 398): HR 0.77 (95% CI: 0.50, 1.20), CVP (n = 118): HR 0.63 (95% CI: 0.32, 1.21), 
and bendamustine (n = 686): HR 0.61 (95% CI: 0.43, 0.86).  
 
Patient Reported Outcomes  
 
Based on the FACT-Lym questionnaire collected during treatment and follow-up phases, patients in 
both treatment arms experienced clinically meaningful improvements in lymphoma-related symptoms 
as defined by a ≥ 3 point increase from baseline in the Lymphoma subscale, a ≥ 6 point increase from 
baseline in the FACT Lym TOI and a ≥ 7 point increase from baseline in the FACT Lym Total score. 
EQ-5D utility scores were similar at baseline, during treatment and follow-up. No meaningful 
differences were seen between the arms in HRQOL or health status measures. 
 
Due to the open label design the patient reported outcomes should be interpreted with caution. 
 
Patients with follicular lymphoma who did not respond or who progressed during or up to 6 months 
after treatment with rituximab or a rituximab-containing regimen (study GAO4753g/GADOLIN). 
 
In a phase III, open label, multicentre, randomised clinical study (GAO4753g/GADOLIN), 
396 patients with iNHL who had no response during treatment or who progressed within 6 months 
following the last dose of rituximab or a rituximab-containing regimen (including rituximab 
monotherapy as part of induction or maintenance treatment) were evaluated. Patients were randomised 
1:1 to receive either bendamustine (B) alone (n = 202) or Gazyvaro in combination with bendamustine 



27 
 

(G+B) (n = 194) for 6 cycles, each of 28 days duration. Patients in the G+B arm who did not have 
disease progression (i.e. patients with a complete response (CR), partial response (PR) or stable 
disease (SD)) at the end of induction continued receiving Gazyvaro maintenance once every two 
months for two years or until disease progression (whichever occurred first). Patients were stratified 
according to region, iNHL subtype (follicular versus non-follicular), rituximab-refractory type 
(whether refractory to prior rituximab monotherapy or rituximab in combination with chemotherapy) 
and the number of prior therapies (≤ 2 versus > 2). 
 
The demographic data and baseline characteristics were well balanced between the treatment arms 
(median age 63 years, the majority were Caucasian [88%] and male [58%]). The majority of patients 
had follicular lymphoma (81%). The median time from initial diagnosis was 3 years and the median 
number of prior therapies was 2 (range 1 to 10); 44% of patients had received 1 prior therapy and 34% 
of patients had received 2 prior therapies.  
 
Gazyvaro was given by intravenous infusion as a dose of 1,000 mg on Days 1, 8 and 15 of Cycle 1, on 
Day 1 of Cycles 2-6, and in patients who did not have disease progression, once every two months for 
two years or until disease progression (whichever occurs first). Bendamustine was given intravenously 
on Days 1 and 2 for all treatment cycles (Cycles 1-6) at 90 mg/m2/day when given in combination with 
Gazyvaro or 120 mg/m2/day when given alone. In patients treated with G+ B, 79.4% received all six 
treatment cycles compared to 66.7% of patients in the B arm. 
 
The primary analysis, based on independent Review Committee (IRC) assessment demonstrated a 
statistically significant - 45% reduction in the risk of disease progression or death, in patients with 
iNHL receiving G+B followed by Gazyvaro maintenance, compared with patients receiving 
bendamustine alone. The reduction in the risk of disease progression or death seen in the iNHL 
population is driven by the subset of patients with FL. 
 
The majority of the patients in study GAO4753g had FL (81.1%). Efficacy results from the primary 
analysis in the FL population are shown in Table 9 and Figures 6 and 8. 11.6% of the patients had 
marginal zone lymphoma (MZL) and 7.1% had small lymphocytic lymphoma (SLL). In the non-FL 
population the HR for IRC-assessed PFS was 0.94 [95% CI: 0.49, 1.90].  No definitive conclusions 
could be drawn on efficacy in the MZL and SLL sub-populations. 
 
At final analysis, the median observation time was 45.9 months (range: 0-100.9 months) for FL 
patients in the B arm and 57.3 months (range: 0.4-97.6 months) for patients in the G+B arm, 
representing an additional 25.6 months and 35.2 months of median follow-up in B and G+B arms, 
respectively, since the primary analysis. Only Investigator (INV) assessed endpoints were reported at 
final analysis since IRC assessments did not continue. Overall, the investigator assessed efficacy 
results were consistent with what was observed in the primary analysis. The overall survival (OS) in 
patients with FL was stable with longer follow-up (see Figure 7); the HR for risk of death was 0.71 
(95%CI: 0.51, 0.98).

Patient-reported Outcomes 
 
Due to the open label design the patient reported outcomes should be interpreted with caution. Based 
on the FACT-Lym questionnaire and EQ-5D index scale collected during the treatment and during 
follow-up periods, health-related quality of life was generally maintained in the pivotal study with no 
meaningful difference between the arms. However, in patients with FL the addition of Gazyvaro to 
bendamustine delayed the time to worsening of health-related quality of life as measured by the 
FACT-Lym TOI score by 2.2 months (median 5.6 versus 7.8 months for B and G+B respectively 
HR = 0.83; 95% CI: 0.60, 1.13). 
 
Immunogenicity 
 
Immunogenicity assay results are highly dependent on several factors including assay sensitivity and 
specificity, assay methodology, assay robustness to quantities of Gazyvaro/antibody in the circulation, 
sample handling, timing of sample collection, concomitant medicines and underlying disease. For 
these reasons, comparison of incidence of antibodies to Gazyvaro with the incidence of antibodies to 
other products may be misleading. 
 
Patients in the CLL pivotal study BO21004/CLL11 were tested at multiple time-points for 
anti-therapeutic antibodies (ATA) to Gazyvaro. In patients treated with Gazyvaro 8 out of 140 patients 
in the randomised phase and 2 out of 6 in the run in phase tested positive for ATA at 12 months of 
follow up. Of these patients, none experienced anaphylactic or hypersensitivity reactions that were 
considered related to ATA, nor was clinical response affected. 
 
No post-baseline HAHA (Human Anti-Human Antibody) were observed in patients with iNHL treated 
in study GAO4753g/GADOLIN. In study BO21223/GALLIUM, 1/565 patient (0.2% of patients with 
a post-baseline assessment) developed HAHA at induction completion. While the clinical significance 
of HAHA is not known, a potential correlation between HAHA and clinical course cannot be ruled 
out. 
 
Paediatric population 
 
The European Medicines Agency has waived the obligation to submit the results of studies with 
Gazyvaro in all subsets of the paediatric population in CLLand FL (see section 4.2 for information on 
paediatric use). 
 
5.2 Pharmacokinetic properties 
 
A population pharmacokinetic (PK) model was developed to analyse the PK data in 469 iNHL, 
342 CLL and 130 diffuse large B-cell lymphoma (DLBCL) patients from Phase I, Phase II and Phase 
III studies who received obinutuzumab alone or in combination with chemotherapy.  
 
Absorption 
 
Obinutuzumab is administered intravenously, therefore absorption is not applicable. There have been 
no studies performed with other routes of administration. From the population PK model, after the 
Cycle 6 Day 1 infusion in CLL patients, the estimated median Cmax value was 465.7 μg/mL and 
AUC(τ) value was 8961 μg•d/mL and in iNHL patients the estimated median Cmax value was 
539.3 μg/mL and AUC(τ) value was 10956 μg•day/mL. 
 
Distribution 
 
Following intravenous administration, the volume of distribution of the central compartment (2.98 L 
in patients with CLL and 2.97 in patients with iNHL), approximates serum volume, which indicates 
distribution is largely restricted to plasma and interstitial fluid. 
 



32 
 

Biotransformation 
 
The metabolism of obinutuzumab has not been directly studied. Antibodies are mostly cleared by 
catabolism.  
 
Elimination 
 
The clearance of obinutuzumab was approximately 0.11 L/day in CLL patients and 0.08 L/day in 
iNHL patients with a median elimination t½ of 26.4 days in CLL patients and 36.8 days in iNHL 
patients. Obinutuzumab elimination comprises two parallel pathways which describe clearance, a 
linear clearance pathway and a non-linear clearance pathway which changes as a function of time. 
During the initial treatment, the non-linear time-varying clearance pathway is dominant and is 
consequently the major clearance pathway. As treatment continues, the impact of this pathway 
diminishes and the linear clearance pathway predominates. This is indicative of target mediated drug 
disposition (TMDD), where the initial abundance of CD20 cells causes a rapid removal of 
obinutuzumab from the circulation. However, once the majority of CD20 cells are bound with 
obinutuzumab, the impact of TMDD on PK is minimised. 
 
Pharmacokinetic/pharmacodynamic relationship(s) 
 
In the population pharmacokinetic analysis, gender was found to be a covariate which explains some 
of the inter-patient variability, with a 22% greater steady state clearance (CLss) and a 19% greater 
volume of distribution (V) in males. However, results from the population analysis have shown that 
the differences in exposure are not significant (with an estimated median AUC and Cmax in CLL 
patients of 11282 µg•d/mL and 578.9 µg/mL in females and 8451 µg•d/mL and 432.5 µg/mL in males, 
respectively at Cycle 6 and AUC and Cmax in iNHL of 13172 µg•d/mL and 635.7 µg/mL in females 
and 9769 µg•d/mL and 481.3 µg/mL in males, respectively), indicating that there is no need to dose 
adjust based on gender. 
 
Elderly 
 
The population pharmacokinetic analysis of obinutuzumab showed that age did not affect the 
pharmacokinetics of obinutuzumab. No significant difference was observed in the pharmacokinetics of 
obinutuzumab among patients < 65 years (n=375), patients between 65-75 years (n=265) and patients 
> 75 years (n=171). 
 
Paediatric population 
 
No studies have been conducted to investigate the pharmacokinetics of obinutuzumab in paediatric 
patients. 
 
Renal impairment 
 
The population pharmacokinetic analysis of obinutuzumab showed that creatinine clearance does not 
affect pharmacokinetics of obinutuzumab. Pharmacokinetics of obinutuzumab in patients with mild 
creatinine clearance (CrCl 50-89 mL/min, n=464) or moderate (CrCl 30 to 49 mL/min, n=106) renal 
impairment were similar to those in patients with normal renal function (CrCl ≥ 90 mL/min, n=383). 
Pharmacokinetic data in patients with severe renal impairment (CrCl 15-29 mL/min) is limited (n=8), 
therefore no dose recommendations can be made. 
 
Hepatic impairment 
 
No formal pharmacokinetic study has been conducted in patients with hepatic impairment. 
 



33 
 

5.3 Preclinical safety data 
 
No studies have been performed to establish the carcinogenic potential of obinutuzumab. 
 
No specific studies in animals have been performed to evaluate the effect of obinutuzumab on fertility. 
In repeat-dose toxicity studies in cynomolgus monkeys obinutuzumab had no adverse effects on male 
and female reproductive organs. 
 
An enhanced pre and postnatal development (ePPND) toxicity study in pregnant cynomolgus monkeys 
showed no evidence of teratogenic effects. However, weekly obinutuzumab dosing from post-coitum 
day 20 to delivery resulted in complete depletion of B-cells in infant monkeys at weekly intravenous 
obinutuzumab doses of 25 and 50 mg/kg (2-5 times the clinical exposure based on Cmax and AUC). 
Offspring exposure on day 28 post-partum suggests that obinutuzumab can cross the blood-placenta 
barrier. Concentrations in infant serum on day 28 post-partum were in the range of concentrations in 
maternal serum, whereas concentrations in milk on the same day were very low (less than 0.5% of the 
corresponding maternal serum levels) suggesting that exposure of infants must have occurred in utero. 
The B-cell counts returned to normal levels, and immunologic function was restored within 6 months 
post-partum.  
 
In a 26-week cynomolgus monkey study, hypersensitivity reactions were noted and attributed to the 
foreign recognition of the humanised antibody in cynomolgus monkeys (0.7-6 times the clinical 
exposure based on Cmax and AUC at steady state after weekly administration of 5, 25, and 50 mg/kg). 
Findings included acute anaphylactic or anaphylactoid reactions and an increased prevalence of 
systemic inflammation and infiltrates consistent with immune-complex mediated hypersensitivity 
reactions, such as arteritis/periarteritis, glomerulonephritis, and serosal/adventitial inflammation. 
These reactions led to unscheduled termination of 6/36 animals treated with obinutuzumab during 
dosing and recovery phases; these changes were partially reversible. No renal toxicity with a causal 
relationship to obinutuzumab has been observed in humans.

Package leaflet: Information for the patient 
 

Gazyvaro 1,000 mg concentrate for solution for infusion 
obinutuzumab 

 
 
Read all of this leaflet carefully before you start using 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 or nurse. 
• If you get any side effects, talk to your doctor or nurse. This includes any possible side effects 

not listed in this leaflet. See section 4. 
 
What is in this leaflet 
 
1. What Gazyvaro is and what it is used for  
2. What you need to know before you are given Gazyvaro 
3. How Gazyvaro is given 
4. Possible side effects  
5. How to store Gazyvaro 
6. Content of the pack and other information 
 
 
1. What Gazyvaro is and what it is used for 
 
What Gazyvaro is 
 
Gazyvaro contains the active substance obinutuzumab, which belongs to a group of medicines called 
“monoclonal antibodies”. Antibodies work by attaching themselves to specific targets in your body. 
 
What Gazyvaro is used for 
 
Gazyvaro can be used in adults to treat two different types of cancer 
 
• Chronic lymphocytic leukaemia (also called “CLL”) 

- Gazyvaro is used in patients who have not had any treatment for CLL before and who 
have other illnesses which make it unlikely that they would be able to tolerate a full dose 
of a different medicine used to treat CLL called fludarabine. 

- Gazyvaro is used together with another medicine for cancer called chlorambucil. 
 
• Follicular lymphoma (also called “FL”) 

- Gazyvaro is used in patients who have not had any treatment for FL  
- Gazyvaro is used in patients who have had at least one treatment with a medicine called 

rituximab before and whose FL has come back or got worse during or after this treatment.  
- At the start of treatment for FL, Gazyvaro is used together with other medicines for 

cancer.  
- Gazyvaro can then be used on its own for up to 2 years as a “maintenance treatment”. 

 
How Gazyvaro works 
 
• CLL and FL are types of cancer that affect white blood cells called “B-lymphocytes”. The 

affected “B-lymphocytes” multiply too quickly and live too long. Gazyvaro binds to targets on 
the surface of the affected “B-lymphocyte” cells and causes them to die.   

• When Gazyvaro is given to patients with CLL or FL together with other medicines for  
cancer - this slows down the time it takes for their disease to get worse. 

 



45 
 

 
2. What you need to know before you are given Gazyvaro 
 
You must not be given Gazyvaro if: 
 
• you are allergic to obinutuzumab or any of the other ingredients of this medicine (listed in 

section 6). 
 
If you are not sure talk to your doctor or nurse before being given Gazyvaro. 
 
Warnings and precautions  
 
Talk to your doctor or nurse before you are given Gazyvaro if: 
• you have an infection, or have had an infection in the past which lasted a long time or keeps 

coming back  
• you have ever taken, or been given, medicines which affect your immune system (such as 

chemotherapy or immunosuppressants) 
• you are taking medicines for high blood pressure or medicines used to thin your blood – your 

doctor might need to alter how you take these 
• you have ever had heart problems 
• you have ever had brain problems (such as memory problems, difficulty moving or feeling 

sensations in your body, eyesight problems) 
• you have ever had breathing problems or lung problems 
• you have ever had  “hepatitis B” - a type of liver disease  
• you are due to have a vaccine or you know you may need to have one in the near future. 
 
If any of the above apply to you (or you are not sure), talk to your doctor or nurse before you are given 
Gazyvaro.  
 
Pay attention to the following side effects  
 
Gazyvaro can cause some serious side effects that you need to tell your doctor or nurse about straight 
away. These include:  
 
Infusion related reactions  
 
• Tell your doctor or nurse straight away if you get any of the infusion related reactions listed at 

the start of section 4. Infusion related reactions can happen during the infusion or up to 24 hours 
after the infusion.  

• If you get an infusion related reaction, you may require additional treatment, or the infusion 
may need to be slowed down or stopped. When these symptoms go away, or improve, the 
infusion can be continued. These reactions are more likely to happen with the first infusion. 
Your doctor may decide to stop treatment with Gazyvaro if you have a severe infusion related 
reaction. 

• Before each infusion of Gazyvaro, you will be given medicines which help to reduce possible 
infusion related reactions or “tumour lysis syndrome”.  Tumour lysis syndrome is a potentially 
life-threatening complication, caused by chemical changes in the blood due to the breakdown of 
dying cancer cells (see section 3). 

 
Progressive multifocal leukoencephalopathy (also called “PML”) 
 
• PML is a very rare and life-threatening brain infection that has been reported in very few 

patients having treatment with Gazyvaro.  
• Tell your doctor or nurse straight away if you have memory loss, trouble speaking, difficulty 

walking or problems with your eyesight.  



46 
 

• If you had any of these symptoms before treatment with Gazyvaro, tell your doctor straight 
away if you notice any changes in them. You may need medical treatment. 

 
Infections  
 
• Tell your doctor or nurse straight away if you get any signs of infection after your Gazyvaro 

treatment (see "Infections" in section 4). 
 
Children and adolescents 
 
Do not give Gazyvaro to children or young people under 18 years of age. This is because there is no 
information about its use in these age groups.  
 
Other medicines and Gazyvaro 
 
Tell your doctor or nurse if you are taking, have recently taken or might start taking any other 
medicines. This includes medicines obtained without a prescription and herbal medicines.  
 
Pregnancy  
 
• Tell your doctor or nurse if you are pregnant, think you might be pregnant or are planning to 

have a baby. They will help you weigh up the benefit of continuing Gazyvaro against the risk to 
your baby.  

• If you become pregnant during treatment with Gazyvaro, tell your doctor or nurse as soon as 
possible. This is because treatment with Gazyvaro may affect yours or the baby’s health.  

 
Breast-feeding 
 
• Do not breast-feed during treatment with Gazyvaro or for 18 months after stopping treatment 

with Gazyvaro. This is because small amounts of the medicine may pass into your breast milk. 
 
Contraception 
 
• Use an effective method of contraception while being treated with Gazyvaro. 
• Continue to use effective contraception for 18 months after stopping treatment with Gazyvaro.  
 
Driving and using machines  
 
Gazyvaro is not likely to affect your ability to drive, cycle or use any tools or machines. However, if 
you get an infusion related reaction, (see section 4), do not drive, cycle or use any tools or machines 
until the reaction stops. 
 
 
3. How Gazyvaro is given 
 
How Gazyvaro is given 
 
Gazyvaro is given under the supervision of a doctor experienced in such treatment. It is given into a 
vein as a drip (intravenous infusion) over several hours. 
 
The Gazyvaro treatment 
 
Chronic lymphocytic leukaemia 
 
• You will be given 6 treatment cycles of Gazyvaro in combination with another medicine for 

cancer called chlorambucil. Each cycle lasts 28 days.  



47 
 

• On Day 1 of your first cycle, you will be given part of your first Gazyvaro dose of 100 
milligrams (mg) very slowly. Your doctor/nurse will monitor you carefully for infusion related 
reactions.  

• If you do not have an infusion related reaction following the small part of your first dose, you 
may be given the rest of your first dose (900 mg) on the same day.  

• If you do have an infusion related reaction following the small part of your first dose, you will 
be given the rest of your first dose on Day 2. 

 
A typical schedule is shown below.  
Cycle 1 - this will include three doses of Gazyvaro in the 28 days: 
• Day 1 – part of your first dose (100 mg) 
• Day 2 or Day 1 (continued) – remainder of first dose 900 mg 
• Day 8 – full dose (1,000 mg) 
• Day 15 – full dose (1,000 mg) 
 
Cycles 2, 3, 4, 5 and 6  this will be just one dose of Gazyvaro in the 28 days: 
• Day 1 – full dose (1,000 mg). 
 
Follicular lymphoma 
 
• You will be given 6 or 8 treatment cycles of Gazyvaro in combination with other medicines for 

cancer - each cycle lasts 28 or 21 days depending on which other cancer medicines are given 
together with Gazyvaro. 

• This induction phase will be followed by a “maintenance phase” - during this time you will be 
given Gazyvaro every 2 months for up to 2 years as long as your disease does not progress. 
Based on your disease status after the initial treatment cycles your doctor will decide whether 
you will receive treatment in the maintenance phase. 

• A typical schedule is shown below.  
 
Induction phase 
 
Cycle 1 - this will include three doses of Gazyvaro in the 28 or 21 days depending on which other 
cancer medicines are given together with Gazyvaro: 
• Day 1 - full dose (1,000 mg) 
• Day 8 - full dose (1,000 mg) 
• Day 15 - full dose (1,000 mg). 

 
Cycles 2-6 or 2-8 - this will be just one dose of Gazyvaro in the 28 or 21 days depending on which 
other cancer medicines are given together with Gazyvaro: 
• Day 1 - full dose (1,000 mg). 
 
Maintenance phase 
 
• Full dose (1,000 mg) once every 2 months for up to 2 years as long as your disease does not 

progress. 
 
Medicines given before each infusion  
 
Before each infusion of Gazyvaro, you will be given medicines to lessen the chance of getting infusion 
related reactions or tumour lysis syndrome. These may include: 
 
• fluids  
• medicines to reduce a fever 
• medicines to reduce pain (analgesics) 
• medicines to reduce inflammation (corticosteroids)  
• medicines to reduce an allergic reaction (anti-histamines) 



48 
 

• medicine to prevent tumour lysis syndrome (such as allopurinol). 
 
If you miss a Gazyvaro treatment 
 
If you miss your appointment, make another one as soon as possible. This is because for this medicine 
to be as effective as possible, it is important to follow the dosing schedule.  
 
If you have any further questions on the use of this medicine, ask your doctor or nurse.

The following information is intended for healthcare professionals only: 
 
Posology 
 
Gazyvaro should be administered under the close supervision of an experienced physician and in an 
environment where full resuscitation facilities are immediately available. 
 
Prophylaxis and premedication for tumour lysis syndrome (TLS) 
 
Patients with a high tumour burden and/or a high circulating lymphocyte count (> 25 x 109/L) and/or 
renal impairment (CrCl < 70 mL/min) are considered at risk of TLS and should receive prophylaxis. 
Prophylaxis should consist of adequate hydration and administration of uricostatics (e.g. allopurinol), 
or suitable alternative such as a urate oxidase (e.g. rasburicase) starting 12-24 hours prior to start of 
Gazyvaro infusion as per standard practice. All patients considered at risk should be carefully 
monitored during the initial days of treatment with a special focus on renal function, potassium, and 
uric acid values. Any additional guidelines according to standard practice should be followed. 
 
Prophylaxis and premedication for infusion related reactions (IRRs) 
 
Premedication to reduce the risk of IRRs is outlined in Table 1. Corticosteroid premedication is 
recommended for patients with FL and mandatory for CLL patients in the first cycle (see Table 1). 
Premedication for subsequent infusions and other premedication should be administered as described 
below. 
 
Hypotension, as a symptom of IRRs, may occur during Gazyvaro intravenous infusions. Therefore, 
withholding of antihypertensive treatments should be considered for 12 hours prior to and throughout 
each Gazyvaro infusion and for the first hour after administration.

2 e.g. 1,000 mg acetaminophen/paracetamol 
3 e.g. 50 mg diphenhydramine 

4.If a corticosteroid-containing chemotherapy regimen is administered on the same day as Gazyvaro, the corticosteroid can 
be administered as an oral medicinal productif given at least 60 minutes prior to Gazyvaro, in which case additional IV 
corticosteroid as premedication is not required. 
 
Dose 
 
Chronic lymphocytic leukaemia (in combination with chlorambucil1) 
 
For patients with CLL the recommended dose of Gazyvaro in combination with chlorambucil is shown 
in Table 2. 
 
Cycle 1  
 
The recommended dose of Gazyvaro in combination with chlorambucil is 1,000 mg administered over 
Day 1 and Day 2 (or Day 1 continued), and on Day 8 and Day 15 of the first 28 day treatment cycle. 
Two infusion bags should be prepared for the infusion on Days 1 and 2 (100 mg for Day 1 and 900 mg 
for Day 2). If the first bag is completed without modifications of the infusion rate or interruptions, the 
second bag may be administered on the same day (no dose delay necessary, no repetition of 
premedication), provided that appropriate time, conditions and medical supervision are available 
throughout the infusion. If there are any modifications of the infusion rate or interruptions during the 
first 100 mg the second bag must be administered the following day.  



55 
 

 
Cycles 2 – 6 
 
The recommended dose of Gazyvaro in combination with chlorambucil is 1,000 mg administered on 
Day 1 of each cycle.

For patients with FL, the recommended dose of Gazyvaro in combination with chemotherapy is shown 
in Table 3. 
 
Patients with previously untreated follicular lymphoma 
 
Induction (in combination with chemotherapy2) 
Gazyvaro should be administered with chemotherapy as follows: 
 
• Six 28-day cycles in combination with bendamustine2 or 
• Six 21-day cycles in combination with cyclophosphamide, doxorubicin, vincristine, 

prednisolone (CHOP), followed by 2 additional cycles of Gazyvaro alone or 
• Eight 21-day cycles in combination with cyclophosphamide, vincristine, and 

prednisone/prednisolone/methylprednisolone (CVP).  
 

Maintenance  
 
Patients who achieve a complete or partial response to induction treatment with Gazyvaro in 
combination with chemotherapy should continue to receive Gazyvaro 1,000 mg as single agent 
maintenance therapy once every 2 months for 2 years or until disease progression (whichever occurs 
first). 
 
Patients with follicular lymphoma who did not respond or who progressed during or up to 6 months 
after treatment with rituximab or a rituximab-containing regimen  
 
Induction (in combination with bendamustine2) 
 
Gazyvaro should be administered in six 28-day cycles in combination with bendamustine2.  
 



56 
 

Maintenance  
 
Patients who achieved a complete or partial response to induction treatment (i.e. the initial 6 treatment 
cycles) with Gazyvaro in combination with bendamustine or have stable disease should continue to

Maintenance 
Every 2 months for 2 years or 

until disease progression 
(whichever occurs first) 

 
Management of IRRs (all indications) 
 
Management of IRRs may require temporary interruption, reduction in the rate of infusion, or 
treatment discontinuations of Gazyvaro as outlined below. 
 
• Grade 4 (life threatening): Infusion must be stopped and therapy must be permanently 

discontinued.  
• Grade 3 (severe): Infusion must be temporarily stopped and symptoms treated. Upon resolution 

of symptoms, the infusion can be restarted at no more than half the previous rate (the rate being 
used at the time that the IRR occurred) and, if the patient does not experience any IRR 
symptoms, the infusion rate escalation can resume at the increments and intervals as appropriate 
for the treatment dose (see Tables 4 and 5). For CLL patients receiving the Day 1 (Cycle 1) dose 
split over two days, the Day 1 infusion rate may be increased back up to 25 mg/hr after 1 hour, 
but not increased further.  
The infusion must be stopped and therapy permanently discontinued if the patient experiences a 
second occurrence of a Grade 3 IRR. 



59 
 

• Grade 1-2 (mild to moderate): The infusion rate must be reduced and symptoms treated.  
Infusion can be continued upon resolution of symptoms and, if the patient does not experience 
any IRR symptoms, the infusion rate escalation can resume at the increments and intervals as 
appropriate for the treatment dose (see Tables 4 and 5). For CLL patients receiving the Day 1 
(Cycle 1) dose split over two days, the Day 1 infusion rate may be increased back up to 
25 mg/hr after 1 hour, but not increased further. 

 
Instructions for dilution 
 
Gazyvaro should be prepared by a healthcare professional using aseptic technique. Do not shake the 
vial. Use a sterile needle and syringe to prepare Gazyvaro.  
 
For CLL cycles 2 – 6 and all FL cycles 
 
Withdraw 40 mL of concentrate from the vial and dilute in polyvinyl chloride (PVC) or non-PVC 
polyolefin infusion bags containing sodium chloride 9 mg/mL (0.9%) solution for injection.  
 
CLL only – Cycle 1 
 
To ensure differentiation of the two infusion bags for the initial 1,000 mg dose, it is recommended to 
utilise bags of different sizes to distinguish between the 100 mg dose for Cycle 1 Day 1 and the 
900 mg dose for Cycle 1 Day 1 (continued) or Day 2. To prepare the 2 infusion bags, withdraw 40 mL 
of concentrate from the vial and dilute 4 mL into a 100 mL PVC or non-PVC polyolefin infusion bag 
and the remaining 36 mL in a 250 mL PVC or non-PVC polyolefin infusion bag containing sodium 
chloride 9 mg/ml (0.9%) solution for injection. Clearly label each infusion bag.

No incompatibilities have been observed between Gazyvaro, in concentration ranges from 0.4 mg/mL 
to 20.0 mg/mL after dilution of Gazyvaro with sodium chloride 9 mg/mL (0.9%) solution for injection, 
and: 
• PVC,  polyethylene (PE), polypropylene or polyolefin bags 
• PVC, polyurethane (PUR) or PE infusion sets 
• optional inline filters with product contact surfaces of polyethersulfone (PES), a 3-way stopcock 

infusion aid made from polycarbonate (PC), and catheters made from polyetherurethane (PEU). 
 
Do not use other diluents such as glucose (5%) solution. 
 
The bag should be gently inverted to mix the solution in order to avoid excessive foaming. The diluted 
solution should not be shaken or frozen. 
 
Parenteral medicinal products should be inspected visually for particulates and discolouration prior to 
administration. 
 
After dilution, chemical and physical stability have been demonstrated in sodium chloride 9 mg/mL 
(0.9%) solution for injection at concentrations of 0.4 mg/mL to 20 mg/mL for 24 hours at 2°C to 8°C 
followed by 48 hours (including infusion time) at ≤ 30°C. 
 
From a microbiological point of view, the prepared infusion solution should be used immediately. If 
not used immediately, in-use storage times and conditions prior to use are the responsibility of the user 
and would normally not be longer than 24 hours at 2°C-8°C, unless dilution has taken place in 
controlled and validated aseptic conditions.

{'Title': '2. what you need to know before you are given gazyvaro', 'Section_Content': 'you must not be given gazyvaro if: you are allergic to obinutuzumab or any of the other ingredients of this medicine (listed in section 6). if you are not sure talk to your doctor or nurse before being given gazyvaro. warnings and precautions talk to your doctor or nurse before you are given gazyvaro if: you have an infection, or have had an infection in the past which lasted a long time or keeps coming back you have ever taken, or been given, medicines which affect your immune system (such as chemotherapy or immunosuppressants) you are taking medicines for high blood pressure or medicines used to thin your blood your doctor might need to alter how you take these you have ever had heart problems you have ever had brain problems (such as memory problems, difficulty moving or feeling sensations in your body, eyesight problems) you have ever had breathing problems or lung problems you have ever had "hepatitis b" - a type of liver disease you are due to have a vaccine or you know you may need to have one in the near future. if any of the above apply to you (or you are not sure), talk to your doctor or nurse before you are given gazyvaro. pay attention to the following side effects gazyvaro can cause some serious side effects that you need to tell your doctor or nurse about straight away. these include: infusion related reactions tell your doctor or nurse straight away if you get any of the infusion related reactions listed at the start of section 4. infusion related reactions can happen during the infusion or up to 24 hours after the infusion. if you get an infusion related reaction, you may require additional treatment, or the infusion may need to be slowed down or stopped. when these symptoms go away, or improve, the infusion can be continued. these reactions are more likely to happen with the first infusion. your doctor may decide to stop treatment with gazyvaro if you have a severe infusion related reaction. before each infusion of gazyvaro, you will be given medicines which help to reduce possible infusion related reactions or "tumour lysis syndrome". tumour lysis syndrome is a potentially life-threatening complication, caused by chemical changes in the blood due to the breakdown of dying cancer cells (see section 3). progressive multifocal leukoencephalopathy (also called "pml") pml is a very rare and life-threatening brain infection that has been reported in very few patients having treatment with gazyvaro. tell your doctor or nurse straight away if you have memory loss, trouble speaking, difficulty walking or problems with your eyesight. if you had any of these symptoms before treatment with gazyvaro, tell your doctor straight away if you notice any changes in them. you may need medical treatment. infections tell your doctor or nurse straight away if you get any signs of infection after your gazyvaro treatment (see "infections" in section 4). children and adolescents do not give gazyvaro to children or young people under 18 years of age. this is because there is no information about its use in these age groups. other medicines and gazyvaro tell your doctor or nurse if you are taking, have recently taken or might start taking any other medicines. this includes medicines obtained without a prescription and herbal medicines. pregnancy tell your doctor or nurse if you are pregnant, think you might be pregnant or are planning to have a baby. they will help you weigh up the benefit of continuing gazyvaro against the risk to your baby. if you become pregnant during treatment with gazyvaro, tell your doctor or nurse as soon as possible. this is because treatment with gazyvaro may affect yours or the baby\'s health. breast-feeding do not breast-feed during treatment with gazyvaro or for 18 months after stopping treatment with gazyvaro. this is because small amounts of the medicine may pass into your breast milk. contraception use an effective method of contraception while being treated with gazyvaro. continue to use effective contraception for 18 months after stopping treatment with gazyvaro. driving and using machines gazyvaro is not likely to affect your ability to drive, cycle or use any tools or machines. however, if you get an infusion related reaction, (see section 4), do not drive, cycle or use any tools or machines until the reaction stops.', 'Entity_Recognition': [{'Text': 'gazyvaro', 'Type': 'PRODUCT_NAME', 'BeginOffset': 0, 'EndOffset': 0}, {'Id': 5,
