BERKELEY, Calif., Oct. 06, 2026 (GLOBE NEWSWIRE) — Caribou Biosciences, Inc. (Nasdaq: CRBU), a leading clinical-stage CRISPR genome-editing biopharmaceutical company, today announced that it is exploring strategic alternatives to maximize stockholder value and plans to discontinue further development activities for its two allogeneic CAR-T cell therapy programs, vispa-cel for the treatment of relapsed or refractory (r/r) B cell non-Hodgkin lymphoma and CB-011 for the treatment of r/r multiple myeloma. In line with this decision, Caribou will implement workforce and cost reductions.
“This is an extraordinarily difficult decision, particularly because it is in no way a reflection of our belief that vispa-cel and CB-011 have the potential to benefit patients. Vispa-cel is pivotal trial-ready, with FDA alignment already reached on the phase 3 clinical trial design. We believe both programs have demonstrated the potential for allogeneic CAR-T cell therapies to deliver deep and durable responses, while meaningfully expanding access for patients who urgently need treatment options,” said Rachel Haurwitz, PhD, president and CEO of Caribou. “Unfortunately, despite the progress we’ve made, the current financing environment for allogeneic CAR-T cell therapies has made it increasingly challenging to secure the capital necessary to responsibly advance these programs. As a result, we’ve made the difficult decision to evaluate strategic alternatives and plan to discontinue further development of our allogeneic CAR-T cell therapy programs. We’re deeply grateful to the patients and families who placed their trust in us, the physicians and site teams who partnered with us, and every member of the Caribou team whose skill and commitment brought these programs this far and advanced the field of cell therapy.”
Caribou’s Board of Directors approved initiating a process to evaluate strategic alternatives, including, but not limited to, a merger, acquisition, business combination, or other strategic transactions involving Caribou and/or its assets. Wedbush Securities Inc. has been engaged as the company’s exclusive financial advisor to assist in the strategic evaluation process. Caribou has not set a timeline for the completion of review of strategic alternatives and does not intend to provide further updates unless and until the Board of Directors has approved a course of action, the review process is concluded, or other disclosure is otherwise determined to be appropriate. In conjunction with this announcement, Caribou plans to discontinue further clinical development activities and implement a substantial reduction in workforce, which is expected to be mostly complete in the fourth quarter of 2026.
As of June 30, 2026, Caribou had $113.8 million in cash, cash equivalents, and marketable securities.
About vispacabtagene regedleucel
Vispacabtagene regedleucel (vispa-cel; formerly known as CB-010) is an allogeneic anti-CD19 CAR-T cell therapy evaluated in patients with relapsed or refractory B cell non-Hodgkin lymphoma (r/r B-NHL). To Caribou’s knowledge, vispa-cel is the first allogeneic CAR-T cell therapy in the clinic with a PD-1 knockout, a genome-editing strategy designed to enhance CAR-T cell activity by limiting premature CAR-T cell exhaustion. Vispa-cel is pivotal trial-ready, with FDA alignment already reached on the phase 3 clinical trial design. To Caribou’s knowledge, vispa-cel is the first allogeneic CAR-T cell therapy to demonstrate safety, efficacy, and durability on par with autologous CAR-T cell therapies. The FDA granted vispa-cel Regenerative Medicine Advanced Therapy (RMAT), Fast Track, and Orphan Drug designations for B-NHL.
About CB-011
CB-011 is an allogeneic anti-BCMA CAR-T cell therapy evaluated in patients with relapsed or refractory multiple myeloma (r/r MM). To Caribou’s knowledge, CB-011 is the first allogeneic CAR-T cell therapy in the clinic that is engineered to enable activity through an immune cloaking strategy with a B2M knockout and insertion of a B2M–HLA-E-peptide fusion protein to blunt immune-mediated rejection. Clinical data from the CB-011 CaMMouflage phase 1 trial has demonstrated the potential for deep, durable responses in patients with r/r MM. The FDA granted CB-011 RMAT, Fast Track, and Orphan Drug designations for r/r MM.
