Clinical, Journal, CAR T-Cell Therapy: A BCMAxCD3 bispecific T cell-engaging antibody demonstrates robust antitumor efficacy similar to that of anti-BCMA CAR T cells. (Pubmed Central) - Jun 1, 2021 Here we describe a fully human bsAb (REGN5458) that binds to B-cell maturation antigen (BCMA) and CD3, and compare its antitumor activities vs those of anti-BCMA CAR T cells to identify differences in efficacy and mechanism of action...In head-to-head in vivo studies, BCMAxCD3 bsAb rapidly cleared established systemic MM tumors, whereas CAR T cells cleared tumors with slower kinetics. Thus, using the same BCMA-binding domain, these results suggest that BCMAxCD3 bsAb rapidly exerts its therapeutic effects by engaging T cells already in place at the tumor site, whereas anti-BCMA CAR T cells require time to traffic to the tumor site, activate, and numerically expand before exerting antitumor effects.

[VIRTUAL] Combinatorial Approaches to Enhance Bispecific Anti-Tumor Efficacy () - Apr 4, 2021 - Abstract #PEGS2021PEGS_550; This presentation will describe key preclinical data from Regeneron’s clinical stage T cell redirecting bispecific programs (REGN1979, REGN4018, REGN5458) as well as status updates from the ongoing clinical trials. In addition, data from new combinatorial approaches being taken to enhance bispecific anti-tumor efficacy, focusing on costimulatory bispecifics, will be discussed.

This presentation will describe Regeneron’s bispecific platform and present preclinical data on REGN4018, a clinical-stage, T cell-engaging, bispecific-targeting Muc16 for solid tumor indications. In addition, status updates on Regeneron’s other clinical-stage bispecific antibodies (REGN1979, REGN5458, REGN5678) will be presented, as well as a discussion of new combinatorial approaches being taken to enhance bispecific anti-tumor efficacy.
