What this trial studies

This study evaluates the efficacy and safety of BMS-986453 in patients with relapsed and/or refractory multiple myeloma. Participants must have experienced disease progression after previous treatments and have received at least three prior anti-myeloma regimens. The study involves administering BMS-986453 along with Fludarabine and Cyclophosphamide to assess its therapeutic potential. The goal is to determine how well this dual-targeting approach can manage the disease.

Who should consider this trial

Good fit: Ideal candidates are adults diagnosed with relapsed and/or refractory multiple myeloma who have undergone multiple prior treatments.

Not a fit: Patients with active central nervous system involvement of multiple myeloma or other specific hematological disorders may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide a new effective option for patients with difficult-to-treat multiple myeloma.

How similar studies have performed: Other studies using similar dual-targeting approaches have shown promise, suggesting potential for success in this trial.
