Panelists discuss how the 5-year data from CARTITUDE-1 demonstrate that a substantial subset of patients achieved long-term remission, suggesting a potential shift toward curative therapy.
Five-year follow-up data from CARTITUDE-1 revealed that approximately 30% of patients remained progression free, a historic milestone in relapsed/refractory myeloma. This is the first study to report such long-term results in this setting.
Patients who remained progression free were found to have characteristics like lower baseline tumor burden and more favorable immune profiles, such as higher T-cell fitness and greater expansion of chimeric antigen receptor (CAR) T cells.
Interestingly, high-risk features such as poor cytogenetics and extramedullary disease were evenly distributed among both long-term responders and early relapsers, challenging assumptions about who may benefit most from CAR T-cell therapy.
