What this trial studies

This multi-center, open-label Phase 1/2 study in China aims to assess the safety, tolerability, efficacy, pharmacokinetics, pharmacodynamics, and immunogenicity of CM336 in patients suffering from relapsed or refractory multiple myeloma. The study is divided into two parts: Phase 1 focuses on dose escalation to determine the maximum tolerated dose, while Phase 2 evaluates the efficacy of the recommended dose. Patients will be monitored for their response to the treatment and any adverse effects throughout the study.

Why it matters

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

How similar studies have gone: Other studies have shown promise with similar approaches in treating multiple myeloma, but the specific use of CM336 is novel.
