Clinical Trial Summary

Clinical trial for the safety and efficacy of CS1-targeted CAR-T Cells therapy for relapsed multiple myeloma after BCMA CAR-T cells therapy

Description:

This is a single arm, open-label, single-center study. This study is indicated for relapsed CS1+ multiple myeloma, the selections of dose levels and the number of subjects are based on clinical trials of similar foreign products. 50 patients will be enrolled for this trial. Primary objective is to explore the safety, main consideration is dose-related safety.
