MGX Metagenomi Inc

Metagenomi, Inc. (Nasdaq: MGX), a precision genetic medicines company committed to developing curative therapeutics for patients using its proprietary gene editing toolbox, today announced that the abstract titled “Site-Specific Insertion of Factor VIII Gene Results in Durable Factor VIII Expression in Nonhuman Primates“ has been accepted for an oral presentation at the American Society of Hematology (ASH) 66th Annual Meeting and Exposition being held December 7-10, 2024, in San Diego, CA, and online.

“We are advancing our lead development candidate MGX-001 toward the clinic, with the goal to provide a single, curative treatment for adults and children with hemophilia A. Our upcoming oral presentation at ASH will showcase our preclinical proof-of-concept data in rodents and nonhuman primates. This program is designed to overcome a significant challenge of existing therapies that are not curative and do not prevent breakthrough bleeding, leaving a significant unmet need in the hemophilia A community,” said Brian C. Thomas, PhD, CEO and Founder of Metagenomi.

About Hemophilia A

Hemophilia A is the most common X-linked inherited bleeding disorder, caused by a large variety of mutations in the FVIII gene leading to a loss of functional FVIII protein. Intracranial bleeding is of greatest concern as this can lead to major morbidity and mortality. Bleeding into joints leads to cumulative joint damage and is a major cause of morbidity. Diagnosis of severe disease typically occurs in infancy due to exaggerated bleeding in response to minor injury or routine medical procedures. Prevalence is estimated to be up to 26,500 patients in the US and more than 500,000 patients globally according to the World Federation of Hemophilia (WFH), with the vast majority of patients being male.

About Metagenomi

Metagenomi is a precision genetic medicines company committed to developing curative therapeutics for patients using its proprietary, comprehensive metagenomics-derived toolbox. Metagenomi is harnessing the power of metagenomics, the study of genetic material recovered from the natural environment, to unlock four billion years of microbial evolution to discover and develop a suite of novel editing tools capable of correcting any type of genetic mutation found anywhere in the genome. Its comprehensive genome editing toolbox includes programmable nucleases, base editors, and RNA and DNA-mediated integration systems (including prime editing systems and clustered regularly interspaced short palindromic repeat associated transposases (CAST)). Metagenomi believes its diverse and modular toolbox positions the company to access the entire genome and select the optimal tool to unlock the full potential of genome editing for patients.
