Trial Summary

This project is a Phase I/IIa clinical trial sponsored by Shanghai Keji Pharmaceutical Technology Co., Ltd., primarily enrolling patients with relapsed/refractory multiple myeloma (RRMM) whose disease progressed after or was refractory to at least 3 prior lines of therapy (must include a proteasome inhibitor, an immunomodulatory agent, and an anti-CD38 antibody). The treatment regimen utilizes KQ-2003 autologous chimeric antigen receptor T-cell (CAR-T) injection (a biological product of CAR-T therapy), administered as a single intravenous infusion following lymphodepleting conditioning. The trial is conducted at a total of 10 domestic top-tier hospitals in China, including Peking Union Medical College Hospital, Chinese Academy of Medical Sciences; Institute of Hematology & Blood Diseases Hospital, Chinese Academy of Medical Sciences; Peking University First Hospital; Union Hospital, Tongji Medical College, Huazhong University of Science and Technology; and The First Hospital of China Medical University.
