CRISPR-edited CAR-T cell therapy for multiple myeloma

A Phase 1, Multicenter, Open-Label Study of CB-011, a CRISPR-Edited Allogeneic Anti-BCMA CAR-T Cell Therapy in Patients With Relapsed/Refractory Multiple Myeloma (CaMMouflage Trial)

Phase 1 Interventional Caribou Biosciences, Inc. · NCT05722418

This study is testing a new CAR-T cell therapy called CB-011 to see if it can safely help people with relapsed or hard-to-treat multiple myeloma.

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.

Who should consider this trial

Good fit: Ideal candidates are adults with relapsed or refractory multiple myeloma who have undergone at least three prior lines of treatment.

Not a fit: Patients who have previously received CAR-T cell therapy or have certain health conditions may not benefit from this study.

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 performed: Other studies using CAR-T cell therapies have shown promising results, indicating potential for success with this novel approach.
