Evaluating C-CAR088 for patients with relapsed or refractory multiple myeloma

A Phase Ib/II Study of CBM.BCMA Chimeric Antigen Receptor T Cell Product (C-CAR088) for Treating Patients With Relapsed or Refractory Multiple Myeloma

Phase1; Phase2 Interventional Shanghai AbelZeta Ltd. · NCT05521802

This study is testing a new CAR-T cell therapy called C-CAR088 to see if it can help people with relapsed or refractory multiple myeloma feel better.

What this trial studies

This multicenter, open-label study aims to assess the safety and efficacy of C-CAR088, a B-cell maturation antigen (BCMA) directed CAR-T cell therapy, in patients suffering from relapsed or refractory multiple myeloma. The study consists of two phases: the phase Ib part focuses on determining the recommended phase 2 dose (RP2D) of C-CAR088, while the phase II part will further evaluate its efficacy at the established dose. Participants will undergo a series of procedures including screening, apheresis for CAR-T cell manufacturing, lymphodepletion, and infusion of the CAR-T cells, followed by follow-up visits to monitor outcomes.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with relapsed or refractory multiple myeloma who have received at least three prior lines of therapy.

Not a fit: Patients with central nervous system involvement or those who have had recent stem cell transplants may not benefit from this study.

Why it matters

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

How similar studies have performed: Other studies using CAR-T cell therapies targeting BCMA have shown promising results, indicating potential success for this approach.
