Breyanzi is not given as a pill or injection. It is cell-based therapy, and its administration is a complex series of steps:
Apheresis The first step is collection of the patient’s T-cells. This process occurs through a procedure known as apheresis, whereby blood from the patient is drawn, separated from its T-cells, and returned to the patient. Usually, this process lasts several hours.
The collected T-cells are then sent to a specialized facility where they are genetically engineered to express the CAR (chimeric antigen receptor) that targets CD19. Then, the T-cells are expanded, meaning they multiply in the lab to create many CAR-T cells.
Infusion: After preparation of T-cells, the patient returns to the healthcare facility, where these modified T-cells are infused back into the bloodstream using an intravenous (IV) line. The infusion process usually lasts for about 30 minutes to an hour.
Monitoring: The patient was very closely monitored after the infusion as CAR-T cell therapy could lead to severe side effects such as CRS, neurologic events. Monitoring often takes place in hospital settings for a few days to ensure safety.
Breyanzi works via a process of CAR-T cell therapy. The engineered T-cells have receptors designed to identify and attach to CD19 from the surface of B-cells. CD19 is a transmembrane protein present both on normal and cancerous B-cells. Targeting it, Breyanzi permits one’s T-cells to recognize and destroy cancerous B-cells that are in existence in lymphoma.
After the infusion, modified T-cells circulate through the blood, scan for CD19-positive B cells, and attach to them. That attachment activates the T-cells to kill the cancerous cells through cytolysis, where the T-cells release toxins that lead to the death of the cell being targeted.
Breyanzi is very potent in destroying and eradicating the malignant B-cells especially when other treatments have failed. This includes relapsed or refractory lymphoma.
While Breyanzi is a promising treatment, it is not without risks. The most common side effects include:
CRS: CRS is a systemic inflammatory response when the CAR-T cells become activated and release high quantities of cytokines, which are proteins within the immune system. CRS might lead to fever, fatigue, low blood pressure, respiratory distress, and organ failure. Severe CRS may require in-patient care and certain medications, such as tocilizumab, an immunomodulatory drug.
Neurologic Toxicity: Neurologic toxic effects can include confusion, difficulty in speaking, seizures, and loss of consciousness. They can be reversible but are serious enough and require close monitoring.
Infections: Because CAR-T therapy temporarily weakens the immune system, there is a higher risk of infections such as bacterial, viral, and fungal infections.
Low Counts of Blood Cells: CAR-T cells infusion leads to low counts of red blood cells, white blood cells, and platelets. These low counts can cause anemia, infection, and bleeding.
Cytokine Release Syndrome (CRS) and Neurologic Events: CRS and neurologic toxicities are serious and potentially life-threatening side effects of Breyanzi. These side effects typically occur within the first few days after the infusion, and patients should be closely monitored for at least 7 days after receiving Breyanzi.
Infections: CAR-T therapy can compromise the immune system, leading to a higher risk of infections. Patients may need prophylactic antibiotics and antiviral medications during treatment.
Pregnancy and Breastfeeding: Breyanzi should not be used during pregnancy or breastfeeding. It is not known whether the drug can harm a developing fetus or pass into breast milk, so women should avoid pregnancy for at least 6 months after treatment.
- Vaccines: Live vaccines should be avoided during and after treatment with Breyanzi as it can weaken the immune system, making vaccinations less effective or increasing the risk of infections.
- Immunosuppressive Medications: Using Breyanzi in combination with other immunosuppressive drugs may increase the risk of infections or affect the body’s ability to fight off illnesses.
- Chemotherapy Drugs: Combining Breyanzi with certain chemotherapy agents may increase the risk of serious side effects like bone marrow suppression or severe infections.
- Steroids: High doses of corticosteroids may interfere with the effectiveness of Breyanzi, potentially reducing the immune response during treatment.
Always consult with your healthcare provider for guidance when combining Breyanzi with other treatments.
Breyanzi is administered as a single intravenous infusion after the T-cells have been genetically modified and expanded in the laboratory. The dose is personalized based on the patient’s condition and overall health. The infusion is typically delivered over 30 minutes to an hour, and the patient will be monitored for any immediate reactions.
Breyanzi is a prescription-only product, and the administration may be done only by properly qualified healthcare professionals who have experience in giving CAR-T therapies. The service will be delivered in specialized facilities to manage the potential life-threatening complications like CRS and neurologic toxicity.
1. What is Breyanzi?
Breyanzi (lisocabtagene maraleucel) is a type of CAR T-cell therapy designed to treat certain types of large B-cell lymphoma, a form of non-Hodgkin lymphoma.
2. How does Breyanzi work?
Breyanzi works by modifying a patient’s own T-cells to recognize and attack cancer cells. This involves extracting T-cells from the patient, modifying them in the lab, and then infusing them back into the patient’s bloodstream.
3. What types of lymphoma is Breyanzi used to treat?
Breyanzi is specifically indicated for adults with relapsed or refractory large B-cell lymphoma after two or more lines of systematic therapy, including diffuse large B-cell lymphoma (DLBCL), high-grade B-cell lymphoma, and primary mediastinal B-cell lymphoma.
4. How is Breyanzi administered?
Breyanzi is administered as an intravenous (IV) infusion, typically after the patient undergoes apheresis (a procedure to collect T-cells) and subsequent cell processing.
5. What is the treatment process for Breyanzi?
The treatment process includes T-cell collection, cell modification in a lab (which takes about two weeks), and then the administration of the modified T-cells as an infusion.
6. What are the common side effects of Breyanzi?
Common side effects can include fever, fatigue, headache, low blood cell counts, infusion-related reactions, and neurologic symptoms such as confusion or difficulty speaking.
7. Are there serious side effects associated with Breyanzi?
Yes, serious side effects can include cytokine release syndrome (CRS) and immune effector cell-associated neurotoxicity syndrome (ICANS). These can be severe and require immediate medical attention.
8. Who is eligible for Breyanzi treatment?
Breyanzi is typically prescribed to adults with specific types of relapsed or refractory large B-cell lymphoma who have not responded to at least two prior therapies. Eligibility should be assessed by a healthcare provider.
