labelling for each batch. The concentration is 1-10 million CD34+ cells/ml. 

Excipient with known effect 
 
This medicinal product contains 0.15 mmol sodium per ml (see section 4.4). 
 
For the full list of excipients, see section 6.1. 
 
 
3. PHARMACEUTICAL FORM 
 
Dispersion for infusion. 
A cloudy to clear, colourless to pink dispersion of cells.  
 
 
4. CLINICAL PARTICULARS 
 
4.1 Therapeutic indications 
 
Strimvelis is indicated for the treatment of patients with severe combined immunodeficiency due to 
adenosine deaminase deficiency (ADA-SCID), for whom no suitable human leukocyte antigen (HLA)-
matched related stem cell donor is available (see section 4.2 and section 4.4).  
 
4.2 Posology and method of administration 
 
Strimvelis must be administered in a specialist transplant centre, by a physician with previous experience in 
the treatment and management of patients with ADA-SCID and in the use of autologous CD34+ ex vivo gene 
therapy products.  Strimvelis should only be administered after consultation with the patient and/or family. 
Patients are expected to enrol in a post-treatment registry and will be followed-up long term. 
 



3 

A CD34+ stem cell back-up containing at least 1 million CD34+ cells per kg is required. This should be 
harvested from the patient at least 3 weeks prior to treatment with Strimvelis. The stem cell back-up is 
collected for use as rescue treatment should there be a failure during product manufacture, transplant failure, 
or prolonged bone marrow aplasia after treatment with Strimvelis. 
 
The patient must be able to donate adequate CD34+ cells to deliver the minimum 4 million purified 
CD34+ cells/kg, required for manufacture of Strimvelis. 
 
Strimvelis is intended for autologous use only (see section 4.4). 
 
Before infusion, it must be confirmed that the patient’s identity matches the essential unique patient 
information on the Strimvelis infusion bag(s) and/or container (see sections 4.4 and 6.6).  
 
Pre-treatment conditioning 
It is recommended that 0.5 mg/kg intravenous busulfan be administered every 6 hours on two consecutive 
days starting three days before administration of Strimvelis. The total busulfan dose is 4 mg/kg, divided into 
8 doses of 0.5 mg/kg.  Busulfan plasma levels should be measured after the first dose of each day by serial 
blood sampling using an appropriate method.  If busulfan AUC exceeds 
4000 nanograms/ml*h  (974 µmol/L.minute), the dose should be appropriately reduced based on the AUC. 
 
Premedication 
It is recommended that an intravenous antihistamine be administered 15-30 minutes before the infusion of 
Strimvelis. 
 
Posology 
The recommended dose range of Strimvelis is between 2 and 20 million CD34+ cells/kg. 
 
If the product contains less than 2 million CD34+ cells/kg, the treating physician should make a decision 
whether to proceed with administration, based on an individual benefit risk assessment. Treatment failure 
was observed in a patient treated in the clinical trials with <2 millions CD34+cell/kg. 
 
Strimvelis should be administered once only. 
 
Special populations 
 
Elderly 
Strimvelis is not intended for use in patients >65 years of age, and has not been studied in this age group. 
 
Renal impairment 
Strimvelis has not been studied in patients with renal impairment. No dose adjustment is expected to be 
required. 
 
Hepatic impairment 
Strimvelis has not been studied in patients with hepatic impairment. No dose adjustment is expected to be 
required. 
 
Paediatric population 
The safety and efficacy of Strimvelis in children less than six months of age or over 6 years 1 month has not 
been established (see section 4.4). No data are available.  
 
Method of administration  
 
Strimvelis is for intravenous infusion. 
 
A transfusion administration set with filter should be used.  Only filters intended for use with transfusion sets 
should be used to prevent inadvertent removal of cells from the product.  



4 

 
The infusion rate should not exceed 5 ml/kg/h. The period of administration is approximately 20 minutes 
(see section 6.6).  Following administration, a saline filled 50 ml syringe should be used to flush the bag 
through. 
 
Precautions to be taken before manipulating or administering the product 
 
This medicinal product contains genetically-modified cells. Local biosafety guidelines applicable for such 
products should be followed (see section 6.6). 
 
Strimvelis is not tested for transmissible infectious agents. Healthcare professionals handling Strimvelis 
should therefore take appropriate precautions to avoid potential transmission of infectious diseases. 
 
4.3 Contraindications 
 
Hypersensitivity to the product or to any of the excipients listed in section 6.1. 
 
Current or previous history of leukaemia or myelodysplasia. 
 
Positive test for human immunodeficiency virus (HIV) or presence of any other transmissible infectious 
agent listed in the current EU Cell and Tissue Directive prior to bone marrow harvest. 
 
History of previous gene therapy. 
 
4.4 Special warnings and precautions for use 
 
Strimvelis is intended solely for autologous use and should never be administered to any patient other than 
the original CD34+ cell donor. 
 
In some cases the patient may be unable to receive Strimvelis because of manufacturing issues. After 
notification, the treating physician may need to modify the treatment program of the patient accordingly (i.e. 
terminating the busulfan conditioning and/or administration of the stem cell back up treatment if 
appropriate). 
 
Stage two quality control results will only be available after the product has been infused.  If clinically 
relevant quality issues, such as out of specification results, are identified after Strimvelis has been infused, 
the treating physician will be notified.  The physician should monitor and/or treat the patient as appropriate.  
 
Strimvelis should be used with caution in patients older than 6 years and 1 month and younger than 6 months 
as there are no data from clinical trials in these age ranges. Older patients are typically less able to donate 
high numbers of CD34+ cells which may mean that older patients cannot be treated.  Successful generation of 
T cells after Strimvelis is also likely to be affected by residual thymic function which can become impaired 
in older children.  Use of Strimvelis in patients older than those previously studied should be carefully 
considered and reserved only for occasions where all other reasonable treatment options have been 
exhausted. 
 
Patients who have previously tested positive for hepatitis C can be treated with Strimvelis, provided they 
demonstrate absence of ongoing infection using a nucleic acid test with a limit of quantification of ≤15 
international units/ml. Negative test results are required on at least 3 sequential occasions over a period of at 
least 4 weeks, after completion of treatment for hepatitis C, with the final test conducted no more than 3 days 
prior to cell harvest. 
 
Strimvelis should be used with caution in patients with hypersensitivity to aminoglycosides or bovine serum 
albumin. 
 



5 

No cases of leukaemia or myelodysplasia have been reported following treatment with Strimvelis. However, 
vector insertions into chromosomal regions previously associated with leukaemia in comparable trials of 
gene therapy in Wiskott Aldrich Syndrome, X-SCID and Chronic Granulomatous Disease have been 
documented. Retroviral insertion sites (RIS) have been detected adjacent to or within CCND2 and LMO2 
and there is a potential risk of leukaemic transformation following treatment with Strimvelis. It is 
recommended that patients be monitored long term with at least annual visits for the first eleven years and 
then at 13 and 15 years post treatment with Strimvelis, to include a complete blood count with differential, 
biochemistry and thyroid stimulating hormone.  
 
The long term effects and durability of response to Strimvelis on ADA-SCID are unknown (see section 5.1).   
 
Patients should be closely monitored for the occurrence of severe and opportunistic infections, immune 
reconstitution parameters and the need for replacement intravenous immunoglobulin (IVIG); in case of lack 
of response, it is recommended to introduce other ADA-SCID treatments under the supervision of a 
physician. 
 
There have been cases where treatment with Strimvelis has been unsuccessful. Some patients have had to 
resume long-term enzyme replacement therapy and/or receive a stem cell transplant (see section 5.1). 
 
Non-immunological manifestations of ADA-SCID may not respond to Strimvelis.  
 
No immunogenicity testing has been conducted with Strimvelis. 
 
Patients can develop autoimmunity. 67% (12 of 18) of Strimvelis treated patients had either autoimmune 
antibodies or other manifestations (e.g. autoimmune thrombocytopenia, autoimmune aplastic anaemia, 
autoimmune hepatitis and Guillain-Barré syndrome) (see section 4.8). 
 
Patients treated with Strimvelis should not donate blood, organs, tissues and cells for transplantation, at any 
time in the future. This information is provided in the Patient Alert Card.  
 
T-lymphocyte (CD3+) and NK (CD56+) cell counts improved following treatment with Strimvelis.  Median 
values at 3 years post gene therapy were below the normal range. Continued follow-up is recommended.  
Cases of skin papillomas, abnormal serum protein electrophoresis and one case each of lipofibroma, 
pulmonary mass and decreased T-cell V beta repertoire were reported. No evidence of causality to the 
product has been established.  
 
Adverse events related to the use of central venous catheters (CVCs) have been reported (e.g., serious CVC 
infections and thrombosis in the device). Patients should be closely monitored for potential catheter-related 
events. 
 
Sodium content 
This medicinal product contains 0.15 mmol sodium per ml. To be taken into consideration by patients on a 
controlled sodium diet. 
 
4.5 Interaction with other medicinal products and other forms of interaction 
 
No interaction studies have been performed. Strimvelis is not expected to interact with the hepatic 
cytochrome P-450 family of enzymes or drug transporters.  
 
4.6 Fertility, pregnancy and lactation 
 
Women of childbearing potential 
As Strimvelis will be administered following busulfan conditioning, patients of childbearing potential must 
use reliable barrier contraception during administration of Strimvelis and for at least 6 months afterwards. 
 



6 

Pregnancy 
No clinical data on exposed pregnancies are available. 
Reproductive and developmental toxicity studies were not performed. 
 
Strimvelis should not be used during pregnancy. 
 
Breast-feeding 
It is unknown whether Strimvelis is excreted in human milk. The effect on breast-fed infants of 
administration of Strimvelis to their mothers has not been studied. 
 
Strimvelis should not be administered to women who are breast-feeding. 
 
Fertility 
There are no data on the effects of Strimvelis on human fertility. Effects on male and female fertility have 
not been evaluated in animal studies. 
 
4.7 Effects on ability to drive and use machines 
 
Strimvelis has no or negligible long term influence on the ability to drive and use machines. 
 
4.8 Undesirable effects 
 
Summary of the safety profile 
 
The safety of Strimvelis was evaluated in 18 subjects, with a median duration of follow-up of 12 years. 
Given the small patient population and size of the cohorts, adverse reactions in the table do not provide a 
complete perspective on the nature and frequency of these events.  Serious adverse reactions include 
autoimmunity (e.g. autoimmune haemolytic anaemia, autoimmune aplastic anaemia, autoimmune hepatitis, 
autoimmune thrombocytopenia and Guillain-Barré syndrome). The most commonly reported adverse 
reaction was pyrexia.

Description of selected adverse reactions 
 
Immune reconstitution 
All the identified adverse reactions in the table (apart from those potentially related to busulfan) are 
considered to be related to immune reconstitution, due to their nature and timing.  These autoimmune 
adverse reactions were reported for subjects post-gene therapy. The majority were reported during the 3 
month to 3 year follow-up period and resolved, with the exception of hypothyroidism and positive ANA 
tests.  In addition, the allergy related adverse reactions in the table were reported mostly during the 3 month 
to 3 year follow-up period. 
 
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 data from clinical studies are available regarding overdose of Strimvelis. 
 
 
5. PHARMACOLOGICAL PROPERTIES 
 
5.1  Pharmacodynamic properties 
 



8 

Pharmacotherapeutic group: Immunostimulants, other immunostimulants , ATC code: not yet assigned 
 
Mechanism of action 
After infusion, CD34+ cells engraft in the bone marrow where they repopulate the haematopoetic system 
with a proportion of cells that express pharmacologically active levels of the ADA enzyme. 
 
Following successful engraftment in the patient, the effects of the product are expected to be life-long. 
 
Pharmacodynamic effects 
The median percentages of genetically modified cells in peripheral blood at one year and 3 years after 
treatment, for the patients enrolled in the pivotal study, were 28% (range 6%-92%) and 30% (range 8%-
101%) of CD19+, and 73% (range 20%-100%) and 67% (range 39%-82%) of CD3+ cells, respectively. The 
median percentages of genetically modified cells in peripheral blood at year 8 for the patients enrolled in the 
long-term follow-up were 97% (range 1%-101%) of CD19+, and 101% (range 1%-101%) of CD3+ cells. 
 
The presence of the transgene leads to increased expression of ADA. One year post treatment, median ADA 
activity (mononuclear cells adenosine deaminase) in peripheral blood lymphocytes was 181.2 (range 42.1-
1678.2) nmol/h/mg protein, compared to a baseline median (range) of 80.6 (30.5-92.3) nmol/h/mg protein.  
ADA activity remained increased throughout the duration of the 8 year follow up. 
 
Clinical efficacy and safety 
A total of 18 patients with ADA-SCID were treated with Strimvelis as part of one open-label pivotal trial 
(AD1115611; N=12), two early open-label pilot studies (AD1117054/AD1117056; N=3), and a 
compassionate use program (AD1117064; N=3). Studies evaluated the use of Strimvelis with a range of 
0.9 million – 18.2 million CD34+ cells/kg. All patients received busulfan conditioning prior to gene therapy, 
with most receiving a total dose of 4 mg/kg intravenously over 2 consecutive days prior to CD34+ infusion. 
Four subjects had previously received an unsuccessful stem cell transplant from a haploidentical donor and 
15 of 18 subjects had previously received prior enzyme replacement therapy with 
polyethylene-glycol-modified bovine adenosine deaminase (PEG-ADA). Patients who previously received 
PEG-ADA had this treatment withdrawn 10 to 22 days prior to Strimvelis therapy. The median age across 
the program was 1.7 years (range 0.5 to 6.1) and 61% were males. Eighty three percent were white (56% 
Caucasian/European heritage and 28% Arabic/North African heritage), 11% African American/African, and 
6% Asian. 
 
Patients treated within the pivotal study 
The efficacy of Strimvelis was evaluated in a 3-year open-label, prospective study in children who lacked a 
sibling HLA matched stem cell donor and were either failing to respond adequately to PEG-ADA, were 
intolerant or did not have access to it. 
 
Results at 3 years for patients treated within the pivotal study are presented in Table 1. Treatment with 
Strimvelis resulted in a 100% survival rate at 3 years post therapy, a decrease in the severe infection rate, an 
increase in T-lymphocytes (CD3+) and all subjects having post-baseline venous red blood cell 
deoxyadenosine nucleotide (RBC dAXP) levels below pathological levels (>100 nmol/ml).

* Including data from one patient collected post intervention with PEG-ADA (>3 months treatment) or hematopoietic

a Based on the entire pre-treatment period for severe infections (retrospectively collected), and the data collected at the 
baseline visit for T-lymphocytes. Patient 10 had no baseline value for T-lymphocytes. 
b Based on the 3 year post-treatment period for survival and severe infections, and the data collected at the 3 year visit 
for T-lymphocytes and dAXP. Patient 8 withdrew from the study before 3 year visit, and thus had no data for 
T-lymphocytes and dAXP. 
c Severe infections are those requiring or prolonging hospitalisation. The 3 month hospitalisation period immediately 
post gene therapy was excluded from the calculation 
d dAXP=dAMP+dADP+dATP. dAXP results are based on a responder analysis of the percentage of patients following 
gene therapy who met the definition of adequate metabolic detoxification, therefore baseline value is not applicable. 
e At baseline 9 of 11 (82%) patients had dAXP <100 nmol/ml. All these patients had previously taken PEG-ADA.  
 
T cell function: In the patients treated in the pivotal study, T cell proliferation was demonstrated in response 
to stimulation with anti-CD3 antibodies (median 62629 cpm, range 4531 to 252173) and phytohemaglutinin 
(median 140642 cpm, range 11119 to 505607) at 1 year post gene therapy, and these responses were 
sustained through Year 3. Findings that TREC (T cell receptor excision circles) in peripheral blood 
lymphocytes were increased above baseline (median 141, range 56 to 1542 copies/100ng DNA) at Years 1 
and maintained to 3 post-treatment and that all subjects had evidence of polyclonal V-beta chains at one or 
more time points following gene therapy provides further supportive evidence of functional T cell 
development. 
 
B cell function: All 12 subjects treated in the pivotal study were receiving IVIG therapy at the time of 
screening, and 7 subjects (58%) had discontinued IVIG use during 0-3 years follow-up after gene therapy. 
 
Long-term follow-up 
A 100% survival rate was observed for all 12 subjects treated within the pivotal study and also for the 18 
subjects in the integrated analysis, with a median follow up duration of approximately 12 years. Intervention-
free survival in this pivotal population (defined as survival without the requirement for long-term (≥3 month) 
re-introduction of PEG-ADA, or stem cell transplant) was 92% (11/12 subjects) (82% (14/17 subjects) for 
integrated population). One subject treated in a pilot study did not have PEG-ADA re-introduction data, and 
thus was excluded from the intervention-free survival in the integrated population. Long-term PEG-ADA 
(exceeding 3 months of continuous duration) was used by three subjects; two of these subjects subsequently 
received a sibling-matched stem cell transplant and one subject remained on chronic PEG-ADA treatment. 
Another subject needed transient PEG-ADA administration due to an autoimmune event (see section 4.4). 
 
In those patients treated in the pivotal and long-term follow-up (LTFU) study, the rate of severe infections 
declined throughout the follow-up period (Table 2).

5.2 Pharmacokinetic properties 
 
Strimvelis is an autologous cellular therapy. The nature of Strimvelis is such that conventional studies on 
pharmacokinetics, absorption, distribution, metabolism, and elimination are not applicable. 
 
5.3 Preclinical safety data 
 
Reproductive and developmental studies have not been conducted. 
 
A 4-month biodistribution study was performed in mice.  CD34+ cells derived from healthy human umbilical 
cord blood, transduced with the vector used for the production of Strimvelis, were administered 
intravenously to busulfan-conditioned mice. The majority of mice showed reconstitution of the 
haematopoietic system by the end of the study. Low levels of human cells and vector sequences were also 
detected in non-haematopoietic organs consistent with the presence of blood containing transduced human 
cells. There were no adverse effects on survival, haematological parameters or histopathology of major 
organs, apart from body weight loss and atrophy in the testes and ovaries consistent with administration of 
busulfan. 
 
Carcinogenicity studies have not been conducted as no adequate animal model was available to evaluate the 
tumourigenic potential of Strimvelis due to the inability to achieve long-term engraftment of transduced cells 
in mice.

An updated RMP should be submitted: 
 

• At the request of the European Medicines Agency; 
• Whenever the risk management system is modified, especially as the result of new information being 

received that may lead to a significant change to the benefit/risk profile or as the result of an important 
(pharmacovigilance or risk minimisation) milestone being reached. 

 
• Additional risk minimisation measures 
 
Prior to launch of Strimvelis in each Member State, the Marketing Authorisation Holder (MAH) must agree 
about the content and format of the educational materials for parents/carers and health professionals, 



15 

restricted prescription details and controlled access/product consent form, including communication media, 
distribution modalities, and any other aspects of the programme, with the National Competent Authority.  
 
Strimvelis will be administered at a specialist transplant centre, and by physicians with previous experience 
in the treatment and management of patients with ADA-SCID and the use of autologous CD34+ ex vivo gene 
therapy products. A completed product consent form is required prior to initiating treatment. 
 
The educational materials should address the following safety concerns/key elements: Autoimmunity, 
Unsuccessful response to gene therapy, and Malignancy due to insertional oncogenesis (e.g. leukaemia, 
myelodysplasia). 
 
• Obligation to conduct post-authorisation measures 
 
The MAH shall complete, within the stated timeframe, the below measure: 
 
Description Due date 
Non-interventional PASS: In order to investigate the long term safety and efficacy of 
Strimvelis gene therapy, the MAH should conduct and submit the results of a long term 
prospective, non-interventional follow up study using data from a registry of patients 
with adenosine deaminase severe combined immunodeficiency (ADA-SCID) treated 
with Strimvelis. The MAH will follow up on the risk of immunogenicity, insertional 
mutagenesis and oncogenesis as well as hepatic toxicity. The MAH will review the 
occurrence of angioedema, anaphylactic reactions, systemic allergic events and severe 
cutaneous adverse reactions during the FU period, particularly in those patients who had 
unsuccessful response and received ERT or SCT. The MAH will also evaluate 
intervention-free survival. 
 

The MAH 
shall plan to 
include regular 
progress 
reports of the 
registry in the 
PSUR and

1. What Strimvelis is and what it is used for 
 
Strimvelis is a type of medicine called a gene therapy.  
 
Strimvelis is used to treat a serious condition called ADA-SCID (Adenosine Deaminase-Severe Combined 
Immune Deficiency). With this condition the immune system does not work properly to defend the body 
against infections. People with ADA-SCID cannot produce enough of an enzyme called adenosine 
deaminase (ADA) because the gene to make it is faulty. 
 
Strimvelis is used to treat ADA-SCID when there is no suitable match from a family member to donate stem 
cells from their bone marrow for a transplant. 
 
Strimvelis is made specially for each patient, using the patient’s own bone marrow cells. It works by putting 
a new gene into stem cells in the bone marrow so they can make ADA. 
 
Strimvelis is given by a drip (infusion) into a vein (intravenously). For more information on what happens 
before and during treatment, see section 3, How Strimvelis is given. 
 
 
2. What you need to know before you (or your child) are given Strimvelis 
 
Strimvelis is not suitable for some people 
 



23 

Strimvelis  must not be given if you (or to your child): 
- are allergic to any of the ingredients of this medicine (listed in section 6) 
- have or have had a type of cancer called leukaemia or myelodysplasia 
- have tested positive for HIV or some other infections (your doctor will advise you about this) 
- have already been treated with gene therapy 
 
Warnings and precautions  
 
Talk to your doctor or nurse before you (or your child) are given this medicine. 
 
Strimvelis is made specially from the patient’s own cells. It must never be given to anyone else. 
 
Inserting a new gene into the DNA could cause leukaemia. In clinical trials of gene therapy for other diseases 
(not ADA-SCID), some patients developed leukaemia or other cancers of the blood system. This has not 
been seen in any patient treated with Strimvelis; however, during long-term follow up your doctor has been 
advised to monitor you (or your child) for any signs of leukaemia. 
 
After you (or your child) have been treated with Strimvelis, you or your child will not be able to donate 
blood, organs or tissues at any time in future. This is because Strimvelis is a gene therapy product. 
 
When Strimvelis treatment cannot be completed 
In some cases, it might not be possible to go ahead with the planned treatment with Strimvelis. There are 
several reasons why this might happen, for example: 
 

• if there was a problem at the time the cells were taken for making the medicine 
• if there were not enough of the right type of cells to make the medicine 
• if the medicine got contaminated while it was being made 
• if there was a delay in the medicine reaching the clinic where treatment is being carried out. 

 
In such cases, the doctor will give you (or your child) replacement stem cells, using the backup sample that 
was collected and stored before treatment started (see also section 3, How Strimvelis is given). 
 
You may need other treatment 
Strimvelis goes through a range of tests before it is used.  Because it is given soon after it is made, the final 
results of some of these tests will not be ready before the medicine is given.  If the tests show anything that 
might affect you (or your child), the doctor will treat you as appropriate. 
 
Pregnancy and breast-feeding  
If you are pregnant or breast-feeding, if you think you may be pregnant or are planning to have a baby, tell 
your doctor before you are given this medicine. Strimvelis should not be given to you if you are pregnant. If 
it is possible that you could become pregnant, you must use a barrier contraceptive (such as condoms) during 
treatment and for at least 6 months afterwards. 
 
You should not be given Strimvelis if you are breast-feeding.  It is not known whether the ingredients of 
Strimvelis can pass into breast milk. 
 
Strimvelis contains sodium 
This medicine contains approximately 3.5 mg sodium per millilitre. This should be taken into consideration 
by patients on a controlled sodium diet. 
 
 
3. How Strimvelis is given 
 
Strimvelis is given by a drip (infusion) into a vein (intravenously). It can only be given in a specialised 
hospital, and by a doctor who is experienced in treating patients with ADA-SCID and in using this type of 
medicine. 
 



24 

Strimvelis can only be made if the doctor can collect enough of the right kind of cells from the patient’s own 
bone marrow. 
 
Before Strimvelis is made, the doctor will do tests to make sure that you (or your child) are not carrying 
certain infections (see section 2). 
 
Two samples are collected 
The doctor will collect two samples of bone marrow stem cells before the planned treatment: 

• the backup sample, at least 3 weeks before.  It will be stored, to be given to the patient as 
replacement stem cells if Strimvelis cannot be given or does not work (see ‘When Strimvelis 
treatment cannot be completed’  in section 2) 

• the treatment sample, 4 to 5 days before. It will be used to make the Strimvelis, by putting a new 
gene into the cells. 

 
Before and during Strimvelis treatment 
 
When What is done Why 

 
At least 3 weeks before 
treatment 
 

Backup sample of stem cells 
collected 
 

to be stored as a backup (see 
above) 
 

About 4 to 5 days before 
treatment 
 

Treatment sample of stem cells 
collected 
 

to make Strimvelis (see above) 
 

3 days and 2 days before 
treatment 
 

A medicine called busulfan is 
given four times a day for two 
days (total of 8 doses) 
 

to make the bone marrow ready 
for Strimvelis 
 

About 15 to 30 minutes 
before treatment 
 

An antihistamine medicine may 
be given 
 

to make it less likely that you will 
react to the infusion 
 

Strimvelis is given… by a drip into a vein. 
This will take about 20 minutes 

 
 
4. Possible side effects 
 
Like all medicines, this medicine can cause side effects, although not everybody gets them. The ones marked 
* may be related to busulfan. 
 
Very common side effects  
 

These may affect more than 1 in 10 people: 
 

• runny or blocked nose (allergic rhinitis) 
 

• wheezing, difficulty breathing (asthma) 
 

• inflamed itchy skin (atopic dermatitis, eczema) 
 

• raised temperature (pyrexia)
