Caribou Biosciences announces FDA granted RMAT, FTD to CB-010

Caribou Biosciences announced that the U.S. Food and Drug Administration, FDA, has granted CB-010 Regenerative Medicine Advanced Therapy, RMAT, designation for relapsed or refractory large B cell lymphoma, LBCL, and Fast Track designation, FTD, for relapsed or refractory B cell non-Hodgkin lymphoma. CB-010, an allogeneic anti-CD19 CAR-T cell therapy with a PD-1 knockout, is being evaluated in the company’s ongoing ANTLER Phase 1 clinical trial in patients with r/r B-NHL. CB-010 is the first allogeneic anti-CD19 CAR-T cell therapy in the clinic with a PD-1 knockout, a genome-editing strategy designed to improve the persistence of antitumor activity by limiting premature CAR-T cell exhaustion. "RMAT and Fast Track designations for CB-010 are important recognitions of the significant unmet patient need for an off-the-shelf cell therapy in the treatment of aggressive B-NHL," said Rachel Haurwitz, Ph.D., Caribou’s president and chief executive officer. "Through genome editing with our precision CRISPR chRDNA genome-editing technology, CB-010 has been designed with a PD-1 knockout strategy to improve the persistence of antitumor activity by limiting premature CAR-T cell exhaustion. In our ANTLER Phase 1 trial, 3 of 6 patients treated with CB-010 at dose level 1 maintained a durable complete response at 6 months. We are encouraged that CB-010 has demonstrated early potential as an off-the-shelf cell therapy that may meaningfully rival autologous cell therapies."
