Pronunciation: EYE-de-KAB-ta-jeen-vik-LOO-sel
Brand name: Abecma
Dosage form: suspension for intravenous infusion
Drug class: Miscellaneous antineoplastics
What is idecabtagene vicleucel?
Idecabtagene vicleucel (Abecma) is a CAR T-cell therapy used for treating relapsed or refractory multiple myeloma in certain adults. Abecma is a personalized one-time infusion made from a patient’s white blood cells, which are genetically modified to recognize and attack the multiple myeloma cells.
Idecabtagene vicleucel brand name is Abecma, manufactured by Celgene Corporation, a Bristol-Myers Squibb Company.
Abecma FDA approval was granted for treating relapsed or refractory multiple myeloma (RRMM) in adults who have received at least two prior therapies, including an immunomodulatory agent, proteasome inhibitor, and an anti-CD38 monoclonal antibody.
Idecabtagene vicleucel's FDA approval was based on positive results from the clinical trial KarMMa-3 Study idecabtagene vicleucel patients had a success rate of:
- 72% overall response rate (ORR)
- 28% achieved a stringent complete response
- 25% had a very good partial response
- 19% achieved a partial response
These results highlight idecabtagene vicleucel’s effectiveness in delaying disease progression in pre-treated multiple myeloma patients.
How Does Idecabtagene vicleucel Work?
Idecabtagene vicleucel is a personalized immunotherapy designed to enhance the body's immune response against multiple myeloma. It utilizes genetically engineered autologous T cells to target and eliminate cancer cells. The process works as follows:
- Genetic Modification: The T cells are engineered in a laboratory to express a chimeric antigen receptor (CAR), which specifically recognizes B-cell maturation antigen (BCMA), a protein found on multiple myeloma cells.
- CAR Activation & Targeting: Once infused back into the patient, these modified T cells seek out and bind to BCMA-expressing myeloma cells.
- Cancer Cell Destruction: Upon binding, the CAR T cells become activated, triggering an immune response that leads to the destruction of multiple myeloma cells through cytotoxic mechanisms.
This targeted approach enhances the immune system’s ability to attack multiple myeloma cells, potentially leading to prolonged remission for patients who have exhausted other treatment options.
What is the Idecabtagene vicleucel treatment process?
- Leukapheresis: White blood cells are collected.
- Manufacturing Process: The infusion is created in a specialized lab (takes about 4 weeks).
- Pre-Infusion Chemotherapy: Patients receive three days of chemotherapy before Abecma infusion.
- Infusion: Abecma infusion is administered two days after the completion of lymphodepleting chemotherapy. It is given as an intravenous infusion through a catheter (tube) placed into your vein. Premedication is given 30 to 60 minutes before infusion.
- Monitoring: Patients must remain at the treatment center for at least 7 days post-infusion and within 2 hours of the facility for 4 weeks for safety monitoring.
Your infusion may be delayed for up to 7 days if you have any of the following conditions:
- unresolved serious adverse events (especially pulmonary events, cardiac events, or hypotension), including those after preceding chemotherapies,
- active infections or inflammatory disorders.

Warnings
Cytokine release syndrome or CRS. Idecabtagene vicleucel can cause a very common side effect called cytokine release syndrome, which can be severe or fatal. Symptoms of CRS include fever, difficulty breathing, dizziness or light-headedness, nausea, headache, fast heartbeat, low blood pressure, or fatigue. Tell your healthcare provider right away if you develop fever or any of these other symptoms.
Infections. Idecabtagene vicleucel can increase the risk of life-threatening infections that may lead to death. Tell your healthcare provider right away if you develop fever, chills, or any signs or symptoms of an infection. It may also lower one or more types of blood cells (red blood cells, white blood cells, or platelets), which may make you feel weak or tired or increase your risk of severe infection or bleeding. After treatment, your healthcare provider will test your blood to check for this. Tell your healthcare provider right away if you get a fever, are feeling tired, or have bruising or bleeding.
Other cancer risk. Abecma may increase your risk of getting cancer including certain types of blood cancers, called T-cell malignancies. Your healthcare provider should monitor you for these.
Nerve problems. Idecabtagene vicleucel may also cause life-threatening nerve problems, blood disorders, or other life-threatening reactions. Tell your caregivers or seek emergency medical attention if you have problems with speech, problems with thinking or memory, confusion, seizures, fatigue, shortness of breath, or chest pain.
Having idecabtagene vicleucel in your blood may cause a false-positive human immunodeficiency virus (HIV) test result by some commercial tests.
It is important that you tell your healthcare providers that you have received idecabtagene vicleucel and to show them your Patient Wallet Card. Your healthcare provider may give you other medicines to treat your side effects.
