GPRC5D-Targeted CAR T-Cell Therapy for RRMM: Phase 1 Study Outcomes of BMS-986393 (CC-95266)

Dr. Susan Bal presents the interim results of a phase one multi-center open-label study evaluating the clinical activity of BMS 986393, a GPRC5D directed autologous CAR T-cell therapy, in patients with relapsed refractory multiple myeloma. The study aimed to target B-cell maturation antigen (BCMA) and explore additional targets for CAR T-cell therapy. The results showed a favorable safety profile with manageable toxicities, primarily hematologic. Cytokine release syndrome (CRS) and immune effector cell-associated neurotoxicity syndrome (ICANS) were observed but mostly low-grade and reversible. The overall response rate was 86.5%, with a complete response rate of 38.5% across all dose levels. Responses were also observed in patients who had prior BCMA-directed therapy. The preliminary data supports BMS-986393 as a potential treatment option for relapsed myeloma patients, regardless of their prior BCMA-directed therapy status. BMS-986393 is a GPRC5D directed autologous CAR T-cell therapy. The study aimed to target B-cell maturation antigen (BCMA) and explore additional targets for CAR T-cell therapy. 67 patients with relapsed refractory multiple myeloma were treated in the study. Eligible patients had at least three prior lines of treatment, including a proteasome inhibitor, an immunomodulatory agent, and a CD38 molecule antibody. Most patients (78%) on the study were triple-class refractory. The maximum tolerated dose was not exceeded. Most grade 3 and 4 toxicities were primarily hematologic, consistent with CAR T-cell therapy in relapsed myeloma. Cytokine release syndrome (CRS) occurred in 87% of patients, mostly low-grade, with a median duration of four days. Immune effector cell-associated neurotoxicity syndrome (ICANS) occurred in 10% of patients, mostly low-grade, and reversible. High-grade infections occurred in about 15% of the subjects. Soluble BCMA, a marker of tumor burden, was decreased at all dose levels. The overall response rate was 86.5%, with a complete response rate of 38.5% across all dose levels. Responses were observed in patients who had prior BCMA-directed therapy. Pharmacokinetic analysis showed fast expansion and multi-phasic decline following IV infusion. Further development planning for BMS-986393 is ongoing. Authors: Susan Bal, Jesus Berdeja, Myo Htut, Mehmet Kocoglu, Tara Gregory, Larry D.
