Full Press Release Details
- Potential best-in-class extrahepatic in vivo gene editing with all-in-one delivery to the central nervous system (CNS) is a critical milestone for the treatment of neurological disorders -
- Advancements demonstrate the ability to specifically integrate correct copies of complete genes, potentially enabling treatment of any disease caused by a loss-of-function mutation -
EMERYVILLE, Calif., May 14, 2025 (GLOBE NEWSWIRE) -- Metagenomi, Inc. (Nasdaq: MGX), a precision genetic medicines company committed to developing curative therapeutics for patients using its proprietary gene editing toolbox, today announced the presentation of three abstracts at the American Society of Gene & Cell Therapy (ASGCT) 28thAnnual Meeting, taking place from May 13 – 17, 2025, in New Orleans, Louisiana. The data showcase Metagenomi’s advancements in compact nucleases for extrahepatic gene editing and CAST (CRISPR-associated transposases) for site-specific integration of large therapeutic genes - underscoring the platform’s potential to drive next-generation, in vivo precision medicines.
“Our metagenomics discovery platform is designed to systematically identify and optimize novel gene editing systems by harnessing both natural microbial evolution and AI-guided protein optimization,” said Brian C. Thomas, Ph.D., CEO and founder of Metagenomi. “At ASGCT, we shared early proof-of-concept data across different gene editing technologies - including compact Type II and Type V nucleases for efficient in vivo editing and a programmable Type V-K CAST system capable of targeted integration of large DNA cargoes. While compact nucleases have the potential to improve delivery to hard-to-reach tissues, CAST are promising new tools to address one of the greatest challenges in gene editing - targeted and precise large gene integration.”
“There remains a need for compact gene editors that can be efficiently delivered via a single AAV - especially for targeting extrahepatic tissues,” said Chris Brown, Ph.D., Head of Discovery at Metagenomi. “Our in vivo AAV data presented at ASGCT demonstrates streamlined, all-in-one delivery of our ultra-compact systems for efficient gene editing in the CNS. By having both Type II and Type V nucleases in our toolbox, we can select the optimal editor based on the target and application. In parallel, our work to discover and engineer a differentiated CAST system has unlocked a key translational milestone - enabling efficient, programmable integration of large gene payloads across multiple in vitro mammalian cell-based models.”
Key highlights from the company’s three poster presentations at ASGCT are below.
A Compact and Potent Type II CRISPR System for CNS Gene Knockdown via AAV Delivery
In Vivo Genome Editing with an Ultra-Compact Type V Nuclease for All-In-One AAV Delivery
Site-Specific Integration of Therapeutic Transgenes with a Type V-K CAST System Engineered for Efficient and Targeted Human Genome Editing
