Biology:ALLO-715

From HandWiki

ALLO-715 is a CAR-T therapy by Allogene Therapeutics that targets B-cell maturation antigen (BCMA).[1] (As of June 2021), it is undergoing clinical trials for the treatment of multiple myeloma.[2] On 21 April 2021, Allogene Therapeutics announced that the Food and Drug Administration has granted Regenerative Medicine Advanced Therapy status to ALLO-715.[3]

Medical uses

CAR-T therapies target a patient's own T cells to respond to a particular antigen. Most CAR-T therapies on the market are autologous, that is, they rely on cells extracted from the patient, processed and reinfused.[4] Tisagenlecleucel (Kymriah), for instance, is made by extracting the patient's blood, filtering T cells and processing them.[5] Allogeneic CAR-T therapies may be able to dispense with this process through using TALEN gene editing technology and using T cells from healthy donors, obtained by leukapheresis. ALLO-715 is being investigated at Memorial Sloan Kettering Cancer Center and the Mayo Clinic[6] as part of the UNIVERSAL trial for multiple myeloma, on its own and in conjunction with the selective gamma secretase inhibitor nirogacestat.[2] Initial results of the UNIVERSAL trial were reported in late 2020 to be promising.[7]
