Caribou Biosciences Reports Positive Additional Data from CB-010 Allogeneic CAR-T Cell Therapy Phase 1 ANTLER Trial at the European Hematology Association (EHA) 2022 Hybrid Congress

Current TAP Partner


BERKELEY, Calif., June 10, 2022 - Caribou Biosciences, Inc. (Nasdaq: CRBU), a leading clinical-stage CRISPR genome-editing biopharmaceutical company, today announced the presentation of additional initial clinical data from its ANTLER Phase 1 trial for CB-010 in patients with relapsed or refractory B cell non-Hodgkin lymphoma (r/r B-NHL). Following a single dose at the initial dose level of CB-010, a 100% complete response (CR) rate (6 of 6 patients) was observed as best response. At 6 months following the single dose of CB-010, 40% of patients remained in CR (2 of 5 patients) as of the May 13, 2022 data cutoff date. The data are being presented at the European Hematology Association (EHA) 2022 Hybrid Congress, being held in Vienna, Austria, June 9-17, 2022.

Based on promising initial safety and efficacy data from cohort 1 at dose level 1 (40x106 CAR-T cells), the ANTLER trial is now enrolling patients in cohort 2 at dose level 2 (80x106 CAR-T cells). Additional data are expected by year end.

Details of the poster presentation at EHA are as follows:
