Pts received a single BMS-986354 infusion 2–7 days after lymphodepleting chemotherapy (3 days fludarabine [30 mg/m2] and cyclophosphamide [300 mg/m2])...Median onset was day 4 (range, 2–8), median duration was 4 days (range, 1–8), and common treatments included tocilizumab (n = 38), steroids (n = 25), and anakinra (n = 9)... BMS-986354, a NEX-T investigational BCMA-targeted CAR T-cell product, is a less differentiated, more potent cellular drug product than orva-cel and can be manufactured with a more rapid processing time. At low doses, BMS-986354 demonstrated a favorable safety profile and promising efficacy, including deep and durable responses in pts with heavily pretreated RRMM. The study continues to enroll patients in the dose-expansion phase.
