Summary of the risk management plan (RMP) for Blincyto (blinatumomab)
This is a summary of the risk management plan (RMP) for Blincyto, which details the measures to be taken in order to ensure that Blincyto is used as safely as possible. For more information on RMP summaries, see here. This RMP summary should be read in conjunction with the EPAR summary and the product information for Blincyto, which can be found on Blincyto’s EPAR page.
Overview of disease epidemiology Blincyto is a cancer medicine used to treat adult patients with B-precursor acute lymphoblastic leukaemia (ALL), a type of blood cancer. In B-precursor ALL, certain cells that give rise to B-cells (a type of white blood cell) multiply too quickly and eventually these abnormal cells replace normal blood cells. Blincyto is used when the ALL has come back or has not responded to previous treatment. It is used when the patients are ‘Philadelphia-chromosome-negative’ (Ph-). This means that they do not have the Philadelphia chromosome, a special chromosome formed when some of the genes are re-arranged, and which is found in some patients with ALL. Acute lymphoblastic leukemia occurs in approximately 27 of every 100,000 people in the European Union. Approximately 40% of the cases are in adults. Risk factors for acute lymphoblastic leukemia include gender (male), race (white), and age (above 70 years). Approximately 35% of patients aged 18 to 60 years with acute lymphoblastic leukemia survive for at least 5 years or longer.
Summary of treatment benefits Blincyto contains blinatumomab, a type of antibody, as the active substance. It has been studied in one main study in 189 patients with Ph- B-cell precursor ALL whose leukaemia had come back or had not responded to treatment. Patients were given Blincyto for up to five treatment cycles. In this study, Blincyto was not compared with any other treatment. The main measure of effectiveness was based on the percentage of patients who, after two treatment cycles, responded to treatment, measured as resolution of signs of leukaemia and complete or partial normalisation of blood cell counts. The study showed that 42.9% (81 out of 189) of patients given Blincyto responded to treatment. In those patients who had a response, in most cases there was no evidence of cancer cells left. The average survival time before the cancer came back was around 6 months, which could enable suitable patients to undergo a blood stem cell transplant.
Unknowns relating to treatment benefits The treatment benefits of Blincyto have not been studied in certain populations such as patients with liver or kidney disease, HIV positive patients or patients with hepatitis B or C infection, children and Page 1/10
adolescents, elderly patients and patients receiving other cancer medicines (such as immunotherapy or radiotherapy).

Patients should immediately inform their doctor, pharmacist or nurse if they experience fits, difficulty in speaking, confusion and disorientation or loss of balance. It is recommended that a neurological examination is performed in patients before starting Blincyto therapy and that patients are clinically monitored for signs and symptoms of neurologic events (e.g. writing test). In case of neurological problems treatment may have to be interrupted. In patients who develop fits, anticonvulsant medicines may be needed.

Because of the potential for progressive multifocal leukoencephalopathy (PML), patients should be monitored for signs and symptoms. If these are consistent with PML events, the doctor should consider referral to a neurologist, brain MRI and examination of cerebral spinal fluid. No cases of PML were reported during the main study with Blincyto.

There is little experience with Blincyto in patients who have leukaemia cells in the brain or cerebrospinal fluid. However patients have been treated with Blincyto in clinical studies after clearance of ALL by directly infusing Blincyto in the brain/spinal cord areas (such as intrathecal chemotherapy). Therefore once the ALL is cleared in brain/spinal cord areas, treatment with Blincyto may be initiated. Blood disorders,

Summary of risk minimisation measures by safety concern All medicines have a summary of product characteristics (SmPC) which provides physicians, pharmacists and other healthcare professionals with details on how to use the medicine, and also describes the risks and recommendations for minimising them. Information for patients is available in lay language in the package leaflet. The measures listed in these documents are known as ‘routine risk minimisation measures’. The SmPC and the package leaflet are part of the medicine’s product information. The product information for Blincyto can be found on Blincyto’s EPAR page. This medicine has special conditions and restrictions for its safe and effective use (additional risk minimisation measures). Full details on these conditions and the key elements of any educational material can be found in Annex II of the product information which is published on Blincyto’s EPAR
Page 6/10
page; how they are implemented in each country however will depend upon agreement between the marketing authorisation holder and the national authorities. These additional risk minimisation measures are for the following risks:
Neurological events and medication errors Risk minimisation measure: Educational materials for doctors, pharmacists, nurses, and patients (including caregivers). In addition, patients will also receive a patient alert card. Objective and rationale: To provide advice on how to prevent neurological events; to reduce the risk of medication errors. Description: Educational material will be provided to patients, caregivers, doctors, nurses and pharmacists. These will stress the importance of reporting side effects, how to administer Blincyto and how to reduce the risk of medication errors while using the infusion pump. It will also include a description of the main signs and/or symptoms of neurological events and the importance of notifying the treating doctor or nurse immediately if symptoms occur.
