BCMA × CD3 bispecific antibody · relapsed/refractory multiple myeloma Phase II clinical trial

Official protocol title:An Open-Label, Single-Arm, Phase II Clinical Study Evaluating CX13-608 in Participants with Relapsed or Refractory Multiple Myeloma

Sponsor: Ningbo Shengjian Biotechnology Co., Ltd.Updated: 9/7/2026
Target CohortRelapsed/refractory(Synthesized by CMDN from protocol summary; final eligibility confirmed by study doctors)

Trial Summary

This project is a Phase II clinical trial sponsored by Ningbo Shengjian Biotechnology Co., Ltd., primarily targeting patients with multiple myeloma who have received at least 2 prior therapy regimens (which must include an alkylating agent or anthracyclines, bortezomib, and an immunomodulatory drug) and have demonstrated relapsed/refractory disease to their most recent regimen. The treatment regimen utilizes the chemical drug CX13-608 (intravenous) in combination with low-dose dexamethasone (oral), administered in 28-day treatment cycles (administered 3 days per week for 3 consecutive weeks, with rest in week 4), with continuous treatment. The trial is conducted across a total of 10 top domestic hospitals in China, including the Institute of Hematology & Blood Diseases Hospital, Chinese Academy of Medical Sciences (Tianjin Institute of Hematology), Renji Hospital Affiliated to Shanghai Jiao Tong University School of Medicine, The First Affiliated Hospital, Zhejiang University School of Medicine, Peking University Third Hospital, and Sun Yat-sen University Cancer Center.
