lifileucel - Medications

AMTAGVI (lifileucel) is a tumor-derived autologous T cell immunotherapy comprised of a suspension of tumor-derived T cells for intravenous infusion. AMTAGVI is manufactured from resected patient tumor tissue prosected from one or more tumor lesions. Immune cells derived from a patient's tumor(s) are expanded in cell culture, washed, formulated as a cell suspension, and cryopreserved. The product must pass a sterility test before release for shipping as a frozen suspension in 1 to 4 patient-specific infusion bag(s) in individual protective metal cassettes. The product is thawed prior to administration back into the same patient [see Dosage and Administration (2.2) , How Supplied/Storage and Handling (16) ] . AMTAGVI is composed primarily of T cells of the CD4+T and CD8+T cell lineages. AMTAGVI may also contain monocytes and other lymphocytes, including B cells and NK cells. AMTAGVI may contain viable melanoma tumor cells from the original tumor tissue used to manufacture the product. The formulation contains 48% PlasmaLyte A, 50% CryoStor CS10 (resulting in final concentration of 5% dimethyl sulfoxide (DMSO)), 2% of 25% human serum albumin (resulting in a final concentration of 0.5% albumin), and 300 IU/mL IL-2 (aldesleukin). A single dose of AMTAGVI is provided in 1 to 4 infusion bag(s) containing 100 mL to 125 mL of viable cells per bag in individual protective cassettes.
