Caribou Biosciences Outlines Pivotal Phase II/III Vispa-cel Trial, Seeks $100M
Caribou Biosciences presented a plan to launch a pivotal Phase II/III trial for its allogeneic CAR-T candidate Vispa-cel enrolling 150 relapsed/refractory B-cell malignancy patients beginning Q3 2026. Management warned that existing funds cover operations only through Q3 2025 and will require at least $100 million in new financing.
1. Vispa-cel Pivotal Trial Plan
At a Citi investor summit, Caribou executives detailed the design of a pivotal Phase II/III trial for Vispa-cel, an allogeneic CAR-T therapy targeting relapsed/refractory B-cell malignancies. The study will enroll 150 patients across multiple centers starting in Q3 2026, with a primary endpoint of complete response rate at six months.
2. Capital Requirements and Cash Runway
Management indicated that existing cash resources will sustain operations only through Q3 2025, after which additional funding will be necessary to advance Vispa-cel into pivotal studies and pre-commercial preparations. They projected a minimum new financing requirement of $100 million and are exploring equity raises or strategic partnerships to secure capital.
3. Regulatory Timeline and Strategy
Caribou plans to complete trial enrollment by early 2028 and file a Biologics License Application by year-end 2028, targeting FDA approval in 2029. The company will pursue accelerated review pathways, including orphan drug designation, to expedite regulatory assessment and market entry.
