JW Therapeutics announced that it has received the Investigational New Drug (IND) clearance from the National Medical Products Administration (NMPA) of China for a clinical trial of BCMA-targeted Chimeric Antigen Receptor (CAR) T cell JWCAR129 in treating relapsed or refractory multiple myeloma (R/R MM). Multiple myeloma (MM) is an incurable blood cancer that starts in the bone marrow and is characterized by an excessive proliferation of plasma cells. Although treatment may result in remission, unfortunately, patients will most likely relapse. While some patients with multiple myeloma have no symptoms at all, most patients are diagnosed due to symptoms that can include bone problems, low blood counts, calcium elevation, kidney problems or infections. Patients who relapse after treatment with standard therapies, including protease inhibitors and immunomodulatory agents, have poor prognoses and few treatment options available. As a result, there is a significant unmet need for patients with R/R MM.
