Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are adults with relapsed or refractory multiple myeloma who have undergone at least three prior lines of treatment.
✕Probably not a fit
Patients who have previously received CAR-T cell therapy or have certain health conditions may not benefit from this study.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This Phase 1 study evaluates the safety and effectiveness of CB-011, an allogeneic CAR-T cell therapy targeting the B cell maturation antigen (BCMA), in patients with relapsed or refractory multiple myeloma. The study aims to determine the optimal dose of CB-011 while assessing its potential to treat patients whose disease has returned or is unresponsive to previous therapies. Participants must have measurable disease and a history of multiple prior treatments, including specific drug classes. The trial will also monitor participants for any adverse effects associated with the therapy.
Why it matters
Potential benefit: If successful, this therapy could provide a new treatment option for patients with difficult-to-treat multiple myeloma.
How similar studies have gone: Other studies using CAR-T cell therapies have shown promising results, indicating potential for success with this novel approach.
