Novel monoclonal antibody targeting CD38 · relapsed/refractory multiple myeloma Phase III clinical trial
Official protocol title:A Randomized, Controlled, Double-Blind, Multicenter Phase III Clinical Trial Evaluating the Efficacy and Safety of SG301 Injection Combined with Pomalidomide and Dexamethasone Versus Placebo Combined with Pomalidomide and Dexamethasone in the Treatment of Relapsed/Refractory Multiple Myeloma (RRMM)
Trial Summary
This project is a Phase III clinical trial sponsored by Hangzhou SJ Biosciences Co., Ltd. (Hangzhou Shangjian Biotechnology Co., Ltd.), primarily targeting participants with relapsed/refractory multiple myeloma (RRMM) who have received at least 1 prior line of therapy, have not previously received pomalidomide, and whose prior anti-CD38 antibody therapy was not determined to be refractory/ineffective. The treatment regimen utilizes an anti-CD38 monoclonal antibody (SG301 injection) combined with an immunomodulator (pomalidomide) and a glucocorticoid (dexamethasone), administered in 4-week (28-day) cycles until disease progression or intolerable toxicity. The trial is being conducted across a total of 78 top domestic hospitals in China, including the Institute of Hematology & Blood Diseases Hospital, Chinese Academy of Medical Sciences; The First Affiliated Hospital of Soochow University; Beijing Chaoyang Hospital, Capital Medical University; The Second Affiliated Hospital, Zhejiang University School of Medicine; and Sun Yat-sen University Cancer Center, among others.
