Metagenomi Reports Business Updates and Second Quarter 2024 Financial Results

Declared development candidate MGX-001 for the treatment of hemophilia A;

plans to present 12-month NHP durability study data in September 2024

All Wave 1 Ionis collaboration programs advancing in lead optimization, unlocking potential for multiple development candidate nominations in 2025

Achieved milestone from partner Affini-T related to Metagenomi licensed technology

Well capitalized with $299.9M in cash, cash equivalents and available-for-sale marketable securities at the end of Q2 2024; cash runway anticipated to support operating plans into 2027

EMERYVILLE, Calif., Aug. 14, 2024 (GLOBE NEWSWIRE) -- Metagenomi, Inc. (NASDAQ:MGX) (Metagenomi), a precision genetic medicines company committed to developing curative therapeutics for patients using its proprietary, comprehensive metagenomics-derived gene editing toolbox, today provided a business update and reported second quarter 2024 financial results.

"We are progressing our pipeline while remaining laser focused on our vision to create curative genetic medicines by harnessing the power of our AI-driven metagenomics platform," said Brian C. Thomas, PhD, CEO and Founder. "We have significantly advanced our wholly-owned program in hemophilia A, including recent positive regulatory interactions with Food and Drug Administration (FDA) and the declaration of MGX-001 as our lead development candidate. Our team has worked diligently to allow us to accelerate the data release from our 12-month nonhuman primate (NHP) durability study from the end of 2024 into September 2024. This study is an important step towards advancing MGX-001 as a potentially life-long curative treatment for both adults and children with hemophilia A, and demonstrating our ability to potentially achieve large targeted gene integration in patients using our metagenomics toolbox."

Dr. Thomas continued, "We are also progressing our partnered programs and advancing our metagenomics-based toolbox. The foundation of our Ionis collaboration was strengthened by the addition of two high-value targets associated with cardiometabolic disease, and all collaboration programs have progressed into the lead optimization phase of development. We achieved a development milestone with Affini-T, where our team provided support for Affini-T's regulatory filing related to Metagenomi licensed technology and current good manufacturing practices (cGMP) material supply. We continue to advance a broad range of technologies to support our goal of being able to address any disease by enabling any therapeutic genome edit in the human genome. Going forward, we remain well capitalized to execute our strategic priorities, with a cash runway into 2027."

Second Quarter 2024 Business Updates and Key 2024-2025 Anticipated Milestones

Therapeutic Pipeline Updates

• Metagenomi continues to advance its wholly-owned lead program in hemophilia A, designed as a one-time curative treatment for both adults and children.
  
  
  
  
  • The company engaged with FDA in the second quarter to discuss key aspects of the planned Investigational New Drug (IND) submission.
    
    
  • The company declared a lead development candidate (DC), MGX-001, meeting previously announced guidance for the timing of a DC nomination.
    
    
  • The company plans to accelerate the release of data from the 12-month NHP durability study for the lead hemophilia A program from late 2024 into September 2024. The 12-month NHP durability study was designed to show therapeutically relevant, durable expression of Factor VIII in NHPs, addressing a key concern which has impacted other genetic medicines programs in hemophilia A that have experienced loss of Factor VIII expression over time.
    
    
  • The company plans to initiate cGMP manufacturing and related IND enabling activities in 2024 and continue IND enabling activities in 2025.
  • As previously disclosed, the company remains on track to file an IND in hemophilia A in 2026.
    
    
    
    
• Building on the recent success of the hemophilia A program, Metagenomi plans to advance additional wholly-owned therapeutic candidates targeting secreted protein disorders, leveraging the MGX-001 editing system with the goal of achieving targeted and durable gene expression.
  
  
  
  
  • This editing system consists of two components: a highly efficient and specific nuclease creates a precise cut at the albumin safe harbor gene locus after delivery by LNP; and an AAV vector delivered FVIII DNA template is inserted into the nuclease cut site by a naturally occurring DNA repair process. 
    
    
    
    
• Following selection of the remaining Wave 1 targets in the Ionis collaboration in the first quarter of 2024, all four therapeutic programs successfully advanced into the lead optimization phase in the second quarter of 2024.  
  
  
  
  
  • All four therapeutic targets in Wave 1 collaboration focus on cardiometabolic diseases; the company announced Refractory Hypertension as the initial disease target leveraging the angiotensinogen pathway.
  • The company aims to demonstrate in vivo proof-of-concept in 2024, and advance NHP studies supporting DC nominations thereafter.
  • The company plans to nominate one to two DCs for cardiometabolic programs in 2025.
    
    
    
    
• The company achieved a milestone in connection with its Affini-T collaboration, establishing cGMP gene editing
  
  reagents for cell therapy and filing related Drug Master Files with FDA to support an IND for Affini-T's T-cell receptor-based therapy.
  
  
  
  
  • Metagenomi received 933,650 shares of Affini-T common stock upon achievement of this regulatory milestone.

Technology Platform Updates

• Metagenomi achieved in vitro proof-of-concept for an undisclosed neuromuscular target with its ultra small editing system, a key milestone, opening up therapeutic potential for extrahepatic disease targets.
• Metagenomi achieved in vitro proof-of-concept using its RNA-mediated integration system (RIGS) for undisclosed liver targets.
• Metagenomi achieved multiplex base editing proof-of-concept and plans to present this data at a scientific conference in the second half of 2024.
• Metagenomi achieved in vitro proof-of-concept in human cells for large gene integration using its potentially industry leading, compact CRISPR-associated transposase (CAST) technology, with a publication planned.
• As previously disclosed, the company remains on track to demonstrate in vivo proof-of-concept for a large gene integration in 2026.

Other Business Updates

• The company continues to exercise fiscal responsibility in prioritizing certain internal development programs while looking for collaboration partners to leverage other development opportunities.
  
  
  
  
  • Metagenomi is looking for a partner or licensee for further development of its program for primary hyperoxaluria type 1 (PH1). Previously disclosed data demonstrated preclinical proof-of-concept in an accepted disease model of PH1.
    
    
  • The company is continuing to focus its internal efforts on in vivo gene editing therapeutic approaches and pursue technology out-licensing for ex vivo cell therapy, where next generation gene editing systems are an important enabler of novel therapies.
  • Going forward, the company is not pursuing amyotrophic lateral sclerosis (ALS) based upon recent peer company clinical data regarding the lack of efficacy of Ataxin-2 as a therapeutic target for ALS.
  • The company is revising its pipeline design to consolidate earlier stage programs and make it easier to identify our near term pipeline priorities focused on in vivo gene editing and liver indications.

• As a result of the acceleration of all four Wave 1 Ionis targets into lead optimization, as well as the company's decision to deprioritize PH1, Metagenomi is revising to provide pipeline guidance only through year-end 2025, including the next one to two DC nominations in 2025. The company is maintaining its guidance for the planned IND filing for hemophilia A in 2026. The updated milestones are available in the corporate presentation on the company website.
