What the company doesAI summary of filing

Caribou Biosciences is a clinical-stage biopharmaceutical company developing allogeneic CAR-T cell therapies using its proprietary CRISPR chRDNA genome-editing technology. The company is advancing two product candidates in clinical trials: vispa-cel, an anti-CD19 CAR-T therapy for relapsed or refractory B cell non-Hodgkin lymphoma, and CB-011, an anti-BCMA CAR-T therapy for relapsed or refractory multiple myeloma. Caribou does not currently generate revenue and is funding its clinical development programs through equity financing and strategic partnerships, with anticipated continued operating losses as it pursues regulatory approval and potential commercialization of its product candidates.

Segments: Vispa-cel (anti-CD19 CAR-T therapy), CB-011 (anti-BCMA CAR-T therapy)
