[CAR T-cell therapy for multiple myeloma]

Chimeric antigen receptor (CAR) T-cell treatment is a novel immunotherapy utilizing the patient's own immune system as a "weapon against tumor cells". In patients with multiple myeloma (MM), CAR T-cell therapy has been investigated in clinical trials. The current data on B‑cell maturation antigen (BCMA)-targeted CAR T-cells have shown impressive efficacy, and official approval is expected shortly. However, the majority of patients relapse after CAR T-cell therapy. Moreover, the treatment can cause severe adverse events such as cytokine release syndrome and neurotoxicity with lethal outcome. The cost-benefit ratio of this treatment also needs to be optimized. Despite these limitations, CAR T-cell therapy represents an attractive option for patients with MM and has the potential to be incorporated into the standard of care.
