Integrated Analysis of B-Cell Maturation Antigen-Specific CAR T Cells (CT053) in Relapsed and Refractory Multiple Myeloma Subjects By High-Risk Factors

Background: For relapsed and refractory multiple myeloma (RRMM), various clinical trials of B-cell maturation antigen-targeted chimeric antigen receptor (CAR) T-cell clinical trials are under way. For one such treatment, CT053, the Phase 1 investigator-initiated CG studies (NCT03380039, NCT03716856, NCT03302403) and the Phase 1 LUMMICAR STUDY 1 (NCT03975907) demonstrated deep and durable responses in heavily pretreated subjects with RRMM. Here we report integrated efficacy and safety of CT053 in Chinese subjects with RRMM based on high-risk factors.
