About CB-010
CB-010 is the lead product candidate of Caribou’s CAR-T allogeneic cell therapy platform and is being evaluated in patients with relapsed or refractory B-cell non-Hodgkin’s lymphoma (r/r B-NHL ) in the ongoing ANTLER Phase 1 trial. CB-010 is an allogeneic anti-CD19 CAR-T cell therapy designed using Cas9 CRISPR hybrid RNA-DNA (chRDNA) technology to insert a CD19-specific CAR into the TRAC gene and knock out PD-1 to stimulate persistence of antitumor activity. CB-010 is the first in-clinic allogeneic CAR-T cell therapy with a PD-1 knockout. Additional information about the ANTLER trial is available at https://clinicaltrials.gov using the identifier NCT04637763.

About Caribou’s New Next Generation CRISPR Platform
CRISPR genome editing uses easy-to-design, modular biological tools to make changes to DNA in living cells. There are two basic components of CRISPR class 2 systems: the nuclease protein that cuts DNA and the RNA molecule(s) that guide the nuclease to generate a site-specific double-strand break, leading to a change in the targeted genomic site. CRISPR systems are capable of editing unintended genomic sites, known as off-target editing, which can lead to adverse effects on cell function and phenotype. In response to this challenge, Caribou has developed hybrid CRISPR RNA-DNA guides (chRDNA; pronounced “chardonnays”) that direct much more precise genome editing compared to all-RNA guides. Caribou deploys the power of its Cas12a chRDNA technology to perform high-efficiency multiple modifications, including multiplex gene insertions, to develop CRISPR-modified therapies.

About Caribou Biosciences, Inc.
Caribou Biosciences is a clinical-stage CRISPR genome-editing biopharmaceutical company dedicated to developing transformative therapies for patients with devastating diseases. The Company’s genome editing platform, including its proprietary Cas12a chRDNA technology, enables superior precision to develop cell therapies specifically designed for enhanced persistence. Caribou is advancing a pipeline of ready-to-use CAR-T and CAR-NK cell therapies for the treatment of patients with hematological malignancies and solid tumors.
