Defining an Optimal Dual-Targeted CAR T-cell Therapy Approach Simultaneously Targeting BCMA and GPRC5D to Prevent BCMA Escape–Driven Relapse in Multiple Myeloma

Abstract excerpt

Abstract Chimeric antigen receptor (CAR) T-cell therapy for multiple myeloma targeting B-cell maturation antigen (TNFRSF17; BCMA) induces high overall response rates; however, relapse occurs commonly. A reservoir of multiple myeloma cells lacking sufficient BCMA surface expression (antigen escape) may be implicated in relapse. We demonstrate that simultaneous targeting of an additional antigen—here, G...
