A CD38xCD28 Costimulatory Bispecific Antibody Demonstrates Potent Preclinical Combinatorial Activity with a BCMAxCD3 T Cell-Engager
(ASH 2024)
- "In RRMM, linvoseltamab activates T cells by engaging the T cell receptor (TCR)/CD3 complex in the presence of BCMA-expressing MM tumor cells leading to tumor cell killing...CD28-targeting bsAbs, including REGN5668 (MUC16xCD28) and REGN5837 (CD22xCD28), are an emerging class of therapeutics capable of providing targeted costimulation and enhancing T cell effector function in combination with CD3-targeted bsAbs...Based on these promising preclinical results, a Phase 1 clinical trial is planned to evaluate the safety, tolerability, and preliminary efficacy of the CD38xCD28 bsAb REGN7945 and the BCMAxCD3 bsAb linvoseltamab in patients with RRMM. This innovative approach, leveraging the combinatorial potential of CD38xCD28 costimulation with linvoseltamab's targeted cytolytic activity, represents a novel therapeutic strategy with the potential to improve RRMM treatment outcomes."

The impact of bispecific antibody CD22xCD28 on anti-tumor efficacy of odronextamab and T cell activation and function in B cell tumor models
(SITC 2025)
- P1 | "Maximal T cell activation and cytotoxicity requires engagement of the T cell receptor/CD3 complex ('signal 1') and additional engagement of a costimulatory receptor such as CD28 ('signal 2'). Importantly, primate studies show REGN5837 has limited activity and no toxicity as a monotherapy but enhances T cell activation when dosed in combination with odronextamab.Conclusions These data highlight a potential chemotherapy-free approach for DLBCL treatment in REGN5837 plus odronextamab, and this combination is currently under evaluation in a Phase 1 clinical trial for aggressive relapsed/refractory DLBCL (NCT05685173).Ethics Approval All procedures were carried out in accordance with the Guide for the Care and Use of Laboratory Animals of the National Institutes of Health. The protocols were approved by the Regeneron Pharmaceuticals Institutional Animal Care and Use Committee (IACUC), and all animals were maintained under pathogen-free conditions."

(AACR 2023)
- P1 | "Secondary endpoints include pharmacokinetics of odronextamab and REGN5837, anti-drug antibody incidence, objective response rate, complete response rate, duration of response, progression-free survival, and overall survival. Enrolment is planned to open in early 2023."
