Bispecific antibodies as bridging to BCMA CAR-T cell therapy for relapsed/refractory multiple myeloma.
Establishing a strategy for sequencing of T cell redirecting therapies for relapsed/refractory multiple myeloma (RRMM) is a pressing clinical need. We longitudinally tracked the clinical and immunological impact of bispecific T cell engaging antibodies (BsAb) as bridging therapy (BT) to subsequent BCMA-directed CAR-T cell therapies in 52 RRMM patients. BsAbs were a potent and safe option for BT, achieving the highest overall response rate (100%) to BT compared to chemotherapy, anti-CD38 or anti-SLAMF7 antibody based regimens (46%). We observed early CD4+CAR+ and delayed CD8+CAR+ T cell expansion in patients receiving BsAb as BT. In vitro cytotoxicity of CAR-T cells was comparable amongst BT options. Single-cell analyses revealed increased clonality in the CD4+ and CD8+ T cell compartments in patients with previous exposure to BsAbs at leukapheresis and on day 30 after CAR-T infusion. This study demonstrates the feasibility and efficacy of BT with BsAbs for CAR-T cell therapy in RRMM.
期刊介绍：
The journal Blood Cancer Discovery publishes high-quality Research Articles and Briefs that focus on major advances in basic, translational, and clinical research of leukemia, lymphoma, myeloma, and associated diseases. The topics covered include molecular and cellular features of pathogenesis, therapy response and relapse, transcriptional circuits, stem cells, differentiation, microenvironment, metabolism, immunity, mutagenesis, and clonal evolution. These subjects are investigated in both animal disease models and high-dimensional clinical data landscapes.
The journal also welcomes submissions on new pharmacological, biological, and living cell therapies, as well as new diagnostic tools. They are interested in prognostic, diagnostic, and pharmacodynamic biomarkers, and computational and machine learning approaches to personalized medicine. The scope of submissions ranges from preclinical proof of concept to clinical trials and real-world evidence.
Blood Cancer Discovery serves as a forum for diverse ideas that shape future research directions in hematooncology. In addition to Research Articles and Briefs, the journal also publishes Reviews, Perspectives, and Commentaries on topics of broad interest in the field.
