Cellular Biomedicine Group Inc. announced that the Food and Drug Administration (FDA) granted clearance of the Investigational New Drug (IND) application to proceed with the Phase 1b clinical development of its chimeric antigen receptor (CAR) T-cell therapy targeting CD19 and CD20 (C-CAR039). C-CAR039 is a novel autologous bi-specific CAR-T therapy targeting both CD19 and CD20 antigens in the treatment of patients with relapsed or refractory non-Hodgkin lymphoma (r/r B-cell NHL). Early clinical results of C-CAR039 from an investigator-initiated trial (IIT) conducted across multiple sites in China demonstrate exciting efficacy and favorable safety data of C-CAR039 in r/r B-cell NHL. As of April 20, 2021, a total of 34 patients received C-CAR039 cell therapies, with 28 patients evaluable for safety analyses and 27 patients evaluable for efficacy analyses. Patients' median age was 55.5 years, and 75% had cancer of Ann Arbor stage III/IV. Patients had a median of three prior lines of therapy. Bridging therapy had been given to 17.9% of patients. The best overall response rate (ORR) was reported to be 92.6%, with a complete response rate (CRR) of 85.2%. Patients had a median time to response of 1.0 month, and at a median follow-up of 7 months, 74.1% of patients continued to be in complete remission. The 6-month estimated progression-free survival rate was 83.2% (95% CI, 69.1%-100.0%). Cytokine release syndrome (CRS) occurred in 96% of patients. 92% of CRS was of grade 1/2 and only 1 patient had grade 3 CSR. Immune effector cell-associated neurotoxicity syndrome occurred at grade 1 in 2 patients and no =grade 2 neurologic events reported in the study. The company will continue to evaluate patients with long follow-up. Separately, in June 2021, the FDA Office of Orphan Products Development granted the company an Orphan Drug Designation to C-CAR039 for the treatment of Follicular Lymphoma, an indolent form of non-Hodgkin lymphoma.
