What exactly is Ciltacabtagene Autoleucel?

Ciltacabtagene Autoleucel is a genetically engineered autologous T cell immunotherapy that is directed by BCMA. Ciltacabtagene Autoleucel is synthesized from the patient’s mononuclear cells in the peripheral blood, which is collected by a conventional leukapheresis process. The mononuclear cells are enriched for T cells and genetically modified ex vivo using a replication-incompetent lentiviral vector to express a chimeric antigen receptor (CAR) with an anti-BCMA targeting domain made up of two single-domain antibodies linked to a 4-1BB costimulatory domain and a CD3-zeta signaling domain.

Anti-BCMA CAR T cells that have been transduced are grown in cell culture, washed, formed into a suspension, and cryopreserved. Before being shipped as a frozen suspension in a patient-specific infusion bag, the product must pass a sterility test. The anti-BCMA CAR T cells are frozen and injected back into the patient, where they may recognize and eradicate BCMA-expressing target cells.¶

Ciltacabtagene Autoleucel may contain Natural Killer (NK) cells in addition to T cells. Dimethyl sulfoxide (DMS) is present in the formulation at a concentration of 5%. (DMSO).

• Ciltacabtagene Autoleucel is a treatment to treat adult patients suffering from bone marrow cancer known as multiple myeloma. It is prescribed in cases where at least four other types of treatment have not been effective or have stopped working.
• Ciltacabtagene Autoleucel is a drug that is made by those white blood cells that you have which have been modified (genetically altered) to be able to recognize and attack the cells of your multiple myeloma.

Mechanisms of Action

• Ciltacabtagene Autoleucel is a BCMA-directed, genetically modified autologous T cell immunotherapy that includes reprogramming a patient’s own T cells with a transgene encoding a chimeric antigen receptor (CAR) that recognizes and kills BCMA-expressing cells. The Ciltacabtagene Autoleucel CAR protein has two BCMA-targeting single-domain antibodies with high avidity for human BCMA, as well as a 4-1BB co-stimulatory domain and a CD3-zeta (CD3-zeta) signaling cytoplasmic domain. The CAR enhances T cell activation, growth, and eradication of target cells after attaching to BCMA-expressing cells.
