Caribou Biosciences Announces Webcast Conference Call to Highlight Initial CB-010 ANTLER Phase 1 Data Presentation at EHA on June 10, 2022

On June 1, 2022 Caribou Biosciences, Inc. (Nasdaq: CRBU), a leading clinical-stage CRISPR genome-editing biopharmaceutical company, reported that the company will host a webcast conference call to share additional initial clinical data from its ANTLER Phase 1 clinical trial of CB-010 in patients with relapsed or refractory B cell non-Hodgkin lymphoma (r/r B-NHL) on Friday, June 10, 2022, at 8:00 am ET (Press release, Caribou Biosciences, JUN 1, 2022, View Source [SID1234615340]). The discussion will include longer duration data on the six patients treated at dose level 1 based on a new data cutoff date.

About CB-010

CB-010 is the lead product candidate from Caribou’s allogeneic CAR-T cell therapy platform and is being evaluated in patients with relapsed or refractory B cell non-Hodgkin lymphoma (r/r B-NHL) in the ongoing ANTLER Phase 1 trial. CB-010 is an allogeneic anti-CD19 CAR-T cell therapy engineered using Cas9 CRISPR hybrid RNA-DNA (chRDNA) technology to insert a CD19-specific CAR into the TRAC gene and knock out PD-1 to boost the persistence of antitumor activity. CB-010 is the first allogeneic CAR-T cell therapy in the clinic with a PD-1 knock out. Additional information on the ANTLER trial can be found at View Source using identifier NCT04637763.

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.
