BERKELEY, CA, Nov. 29, 2022 - Caribou Biosciences, Inc. (Nasdaq: CRBU), a leading clinical-stage CRISPR genome-editing biopharmaceutical company, today 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 for relapsed or refractory B cell non-Hodgkin lymphoma (r/r B-NHL). 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, which can enroll three LBCL subtypes: diffuse large B cell lymphoma (DLBCL), primary mediastinal large B cell lymphoma (PMBCL), and high-grade B cell lymphoma (HGBL). 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.
Both RMAT and Fast Track designations are dedicated programs designed to expedite the development and review processes for promising therapeutic candidates intended to address an unmet medical need in patients with serious conditions. These designations provide important benefits in the drug development process and are designed to facilitate and expedite development and regulatory review, including providing eligibility for Priority and Rolling Reviews, and Accelerated Approval, if relevant criteria are satisfied.
