A Phase 2, Open-Label, Multicenter Study of Ciltacabtagene Autoleucel and Talquetamab for the Treatment of Participants With High-Risk Multiple Myeloma

Phase 2 Interventional Janssen Research & Development, LLC · NCT06550895

This study is testing if two new treatments, Ciltacabtagene Autoleucel and Talquetamab, can help people with high-risk multiple myeloma who haven't responded well to previous therapies.

What this trial studies

This study evaluates the safety and efficacy of two investigational therapies, Ciltacabtagene Autoleucel (Cilta-cel) and Talquetamab, in patients diagnosed with high-risk multiple myeloma. Participants must have experienced disease progression after at least three prior lines of therapy. The study aims to gather data on how well these treatments work in this specific patient population, focusing on measurable disease outcomes. The trial is interventional and is currently in Phase 2.

Who should consider this trial

Good fit: Ideal candidates are adults with a documented diagnosis of multiple myeloma who have undergone multiple lines of therapy and have shown disease progression.

Not a fit: Patients who have previously received CAR-T therapy or specific BCMA-directed therapies may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide a new therapeutic option for patients with high-risk multiple myeloma who have limited treatment alternatives.

How similar studies have performed: Other studies involving CAR-T therapies and monoclonal antibodies have shown promise in treating multiple myeloma, suggesting potential for success with this combination approach.
