A phase 1 study of CB-012, a CRISPR-edited allogeneic CAR-T targeting CLL1, in patients with acute myeloid leukemia

In February 2021, LLS made an equity investment in Caribou Biosciences to "Support allogeneic CD371 (CLL-1) CAR development for acute myeloid leukemia."

Caribou is a clinical-stage biotechnology company, co-founded by CRISPR pioneer and Nobel Prize winner Jennifer Doudna, Ph.D., using next-generation CRISPR genome-editing technology to develop “off-the-shelf” (allogeneic) CAR therapies for hard-to-treat blood cancers.

CB-012, an allogeneic CLL1 CAR-T cell therapy engineered with five genome edits, is the first allogeneic CAR-T cell therapy with both checkpoint disruption through a PD-1 knockout, and immune cloaking. The IND has been cleared by the FDA and a Phase 1 clinical trial for patients with relapsed or refractory acute myeloid leukemia is expected to begin in mid-2024.
