Fourth Quarter 2025 Updates

MGX-001 - Hemophilia A Program

• Announced preclinical data from MGX-001 hemophilia A program that demonstrated curative FVIII activity in NHPs for a therapy with best-in-class treatment potential supporting advancement into clinical development.
• Completed a pre-IND meeting for MGX-001 and remain on track for regulatory submission to advance global clinical program, including an IND in the fourth quarter of 2026, and subject to regulatory clearance, initiate clinical trials in 2027.

Secreted Protein Deficiencies

• Demonstrated in vivo proof-of-concept in NHPs for Antithrombin (AT-III) Deficiency evidencing the potential to expand the MGX-001 site-specific genome integration system into additional curative therapies for secreted protein disorders.
  

Cardiometabolic Indications

• Presented preclinical data supporting APOC3 as a new collaboration target with Ionis Pharmaceuticals (“Ionis”) at the Nature Conference, “Cracking the Code: Nucleic Acid Medicines Coming of Age.”
  • APOC3 is a part of Wave 1 of the Ionis collaboration, which includes four targets in significant cardiometabolic indications.

About Metagenomi Therapeutics

Metagenomi Therapeutics, Inc. is an in vivo genome editing company capitalizing on its proprietary technologies to create curative genetic medicines for patients. The Company was founded on the science of metagenomics, the study of genetic materials recovered from the natural environment, to discover and develop a suite of novel editing tools potentially capable of correcting any type of genetic mutation found anywhere in the human genome. The Company focuses on high value programs in disease indications with well-understood biology and clearly defined clinical development and regulatory pathways. Going forward, the Company intends to continue to expand its pipeline by leveraging its proprietary genetic editing capabilities in site specific deletion, integration and correction.

MGX-001, the Company’s lead, wholly-owned development program in hemophilia A, has demonstrated a preclinical profile potentially competitive with best-in-class treatment options, including targeted genome editing and durable gene expression in a one-time treatment. MGX-001 is designed to provide curative, life-long protection from bleeding events and joint damage in adults and children with hemophilia A. The Company is also currently pursuing other secreted protein deficiencies leveraging the MGX-001 site-specific genome integration system and partnered assets targeting cardiometabolic diseases.
