BERKELEY, Calif., March 05, 2024 (GLOBE NEWSWIRE) -- Caribou Biosciences, Inc. (Nasdaq: CRBU), a leading clinical-stage CRISPR genome-editing biopharmaceutical company, today announced that preclinical data from CB-012, an allogeneic anti-CLL-1 CAR-T cell therapy for the treatment of relapsed or refractory acute myeloid leukemia (r/r AML), will be presented as a poster at the upcoming American Association for Cancer Research (AACR) Annual Meeting 2024, held April 5-10, 2024 in San Diego.
Details of the poster presentation are as follows:

Session: Adoptive Cellular Therapy 2
Location: San Diego Convention Center, poster section 40, poster board 14
Abstract number: 6323
The poster will be available on the Scientific Publications page of Caribou’s website on Tuesday, April 9, 2024 at 1:30 pm PT.
About CB-012
CB-012 is a product candidate from Caribou’s allogeneic CAR-T cell therapy platform being evaluated in the AMpLify Phase 1 clinical trial in patients with relapsed or refractory acute myeloid leukemia (r/r AML). CB-012 is an anti-CLL-1 CAR-T cell therapy engineered with five genome edits, enabled by Caribou’s patented next-generation CRISPR technology platform, which uses Cas12a chRDNA genome editing to significantly improve the specificity of genome edits. To Caribou’s knowledge, CB-012 is the first allogeneic CAR-T cell therapy with both checkpoint disruption, through a PD-1 knockout, and immune cloaking, through a B2M knockout and B2M–HLA-E fusion protein insertion; both armoring strategies are designed to improve antitumor activity. Additional information on the AMpLify trial (NCT06128044) can be found at clinicaltrials.gov.
About Caribou’s novel next-generation CRISPR platform
CRISPR genome editing uses easily designed, modular biological tools to make DNA changes in living cells. There are two basic components of Class 2 CRISPR systems: the nuclease protein that cuts DNA and the RNA molecule(s) that guide the nuclease to generate a site-specific, double-stranded break, leading to an edit at the targeted genomic site. CRISPR systems are capable of editing unintended genomic sites, known as off-target editing, which may lead to harmful effects on cellular function and phenotype. In response to this challenge, Caribou has developed CRISPR hybrid RNA-DNA guides (chRDNAs; pronounced “chardonnays”) that direct substantially more precise genome editing compared to all-RNA guides. Caribou is deploying the power of its Cas12a chRDNA technology to carry out high efficiency multiple edits, including multiplex gene insertions, to develop CRISPR-edited therapies.
