The data demonstrate that chRDNA guides enable highly specific Cas9-mediated editing, with little to no perturbation of on-target efficiency, while the all-RNA guides give rise to multiple unintended off-target editing events across the genome. The study also demonstrates that the number and location of DNA nucleotides in a chRDNA design can be tuned for each intended target site to allow for the maximal level of discrimination between on- and off-target sites. Structural analysis of target-bound Cas9-chRDNA complexes revealed that chRDNAs result in an altered geometry of the chRDNA and target DNA interface, and this alteration is accompanied by structural rearrangements of the Cas9 protein. These changes disfavor off-target DNA binding and modulate Cas9 cleavage activity to inhibit editing at off-target sites.

There are two basic components of Type II 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 occasionally edit 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 chRDNAs (pronounced \u201cchardonnays\u201d), RNA-DNA hybrid guides that direct substantially more precise genome editing compared to all-RNA guides. Caribou is deploying the power of the chRDNA technology to carry out high efficiency multiple edits, including multiplex gene insertions, to develop CRISPR-edited therapies.<\/p>\n<p>\n        <strong>About Caribou Biosciences, Inc.<\/strong><br \/>\n        <br \/>Caribou is a clinical-stage CRISPR genome-editing biopharmaceutical company dedicated to transforming the lives of patients with devastating diseases by applying the company\u2019s proprietary chRDNA technology toward the development of next-generation, genome-edited cell therapies. The company is developing a pipeline of genome-edited, off-the-shelf CAR-T and CAR-NK cell therapies for the treatment of both hematologic malignancies and solid tumors against cell surface targets for which autologous CAR-T cell therapeutics have previously demonstrated clinical proof of concept, as well as additional emerging targets.<\/p>\n<p>\n        <strong>Forward-Looking Statements<\/strong><br \/>\n        <br \/>This press release contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995.
