Trial Summary

This project is a phase 3 clinical trial sponsored by Pfizer, primarily targeting patients with transplant-ineligible or deferred transplant newly diagnosed multiple myeloma (NDMM), as well as a subset of patients with relapsed/refractory multiple myeloma (RRMM) who have received 1–2 prior lines of therapy (including at least 1 immunomodulatory agent and 1 proteasome inhibitor). The treatment regimen evaluates a novel biologic (Elranatamab) combined with an anti-CD38 monoclonal antibody (daratumumab) and an immunomodulatory agent (lenalidomide), administered in 28-day cycles and continuing until disease progression or protocol-defined discontinuation criteria are met. The trial is being conducted across 12 key centers in China, including the Institute of Hematology & Blood Diseases Hospital, Chinese Academy of Medical Sciences (Tianjin Blood Diseases Hospital), Tongji Hospital of Tongji Medical College of Huazhong University of Science and Technology, The First Affiliated Hospital, Zhejiang University School of Medicine, Sun Yat-sen University Cancer Center, and The First Affiliated Hospital of Soochow University, and is running concurrently at 210 top international medical centers across 26 countries and regions including the United States, the United Kingdom, France, Germany, Canada, and Australia.
