Idecabtagene vicleucel // ABECMA

CAR-T ( Chimeric antigen receptor -T cell therapy)

MECHANISM OF ACTION

ABECMA is a chimeric antigen receptor (CAR)-positive T cell therapy targeting B-cell maturation antigen (BCMA), which is expressed on the surface of normal and malignant plasma cells. The CAR construct includes an anti-BCMA scFv-targeting domain for antigen specificity, a transmembrane domain, a CD3-zeta T cell activation domain, and a 4-1BB costimulatory domain. Antigen-specific activation of ABECMA results in CAR-positive T cell proliferation, cytokine secretion, and subsequent cytolytic killing of BCMA-expressing cells// Route of drug elimination is N/A

MECHANISM OF KIDNEY INJURY

renal injury seems to be related to CRS - decreased kidney perfusion vs ATN (but unsure from this drug as no studies done to determined the cause)
