Using Anti-FcRL5 CAR-T Cell Therapy for Relapsed Multiple Myeloma

Efficacy and Safety Study of Anti-FcRL5 CAR-T Cells in Subjects With Relapsed and Refractory Multiple Myeloma

This study is testing a new CAR-T cell therapy to see if it can help people with relapsed multiple myeloma feel better and improve their treatment options.

Quick facts

• Phase: Phase1; Phase2
• Study type: Interventional
• Enrollment: 20 (estimated)
• Ages: 18 Years to 70 Years
• Sex: All
• Sponsor: Xuzhou Medical University (Academic / other)
• Drugs / interventions: immunotherapy, CAR-T, chimeric antigen receptor, cyclophosphamide, fludarabine
• Locations: 1 site (Xuzhou, Jiangsu)
• Trial ID: NCT06196255 on ClinicalTrials.gov

What this trial studies

This open label, single-arm Phase 2 study evaluates the safety and efficacy of Anti-FcRL5 CAR-T cell therapy in patients with relapsed and refractory multiple myeloma. Participants will undergo a leukapheresis procedure to manufacture CAR-modified T cells, followed by lymphodepleting therapy with fludarabine and cyclophosphamide before receiving the CAR-T infusion. The study aims to observe dose-limiting toxicity and determine the maximum tolerated dose to inform future treatment plans.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18-70 with relapsed or refractory multiple myeloma and no effective treatment options.

Not a fit: Patients with serious comorbidities or those who are not suitable for stem cell transplantation may not benefit from this study.

Why it matters

Potential benefit: If successful, this therapy could provide a new treatment option for patients with limited effective therapies for relapsed multiple myeloma.

How similar studies have performed: Other studies using CAR-T cell therapies have shown promising results in treating various hematological malignancies, suggesting potential success for this approach.
