What this trial studies

This study aims to assess the safety and tolerability of combining cevostamab and elranatamab in patients with relapsed or refractory multiple myeloma. It includes a safety lead-in stage followed by an expansion stage to determine the recommended Phase II dose for the treatment. Participants will be monitored for pharmacokinetics and overall activity of the drug combination. The study is designed to provide insights into the effectiveness of this novel treatment approach.

Why it matters

Potential benefit: If successful, this treatment could offer a new therapeutic option for patients with relapsed or refractory multiple myeloma.

How similar studies have gone: While this approach is novel, similar studies targeting multiple myeloma have shown promise in improving patient outcomes.
