GC012F, now renamed AZD0120, is an autologous B-cell maturation antigen and CD19 dual-targeting chimeric antigen receptor (CAR) T-cell product manufactured on the FasTCAR platform. CAR T-cell therapy has not been routinely studied in older patients with newly diagnosed multiple myeloma (NDMM), so we assessed AZD0120 as frontline treatment for patients with MM aged 70 years. In this single arm phase I study, patients with NDMM aged 70 years received 2 cycles of VRD (bortezomib/lenalidomide/dexamethasone) induction therapy followed by AZD0120 infusion at the dose of 1.5 105 or 3 105 cells per kg. Eight patients received AZD0120, with 4 frail and 4 nonfrai according to the Intergroupe Francophone du Myclome Simplified Frailty Score criteria. At a median follow-up of 9.8 months after infusion, hematologic toxicities were the most common grade 3 treatment-emergent adverse events, including lymphopenia (25%), leukopenia (50%), and neutropenia (75%). Four (50%) patients had cytokine release syndrome, all grade 1. No immune effector cell-associated neurotoxicity syndrome was observed. All patients achieved a stringent complete response, and all patients achieved minimal residual discase (MRD) negativity by Euroflow (10-6) at 1 month, with MRD negativity rates of 100% among evaluable patients at month 6 (n = 7) and month 12 (n = 2). Two frail patients with Eastern Cooperative Oncology Group (ECOG) performance status score of 2 improved to score 1 after infusion. AZD0120 CAR T-cell therapy shows promising preliminary efficacy and a manageable safety profile for older patients with NDMM. This trial was registered at www.clinicaltrials.gov as NCT05840107.
