Demonstrated nonhuman primate proof of concept in Hemophilia A program; progressing towards Development Candidate nomination by mid-year; 12-month nonhuman primate durability data in 2H 2024

Proof of capability demonstrated with CRISPR-associated transposase (CAST) system being developed to enable >10,000 base pair, targeted genomic integrations

EMERYVILLE, Calif., March 27, 2024 (GLOBE NEWSWIRE) -- Metagenomi, Inc. (Nasdaq: MGX), a precision genetic medicines company committed to developing curative therapeutics for patients using its proprietary, comprehensive metagenomics-derived gene editing toolbox, today reported financial results for the full year ended December 31, 2023, and additional business updates.

“We continue to execute across all aspects of our business. Throughout 2023, we achieved key therapeutic milestones, including preclinical proof of concept in nonhuman primates for our lead program in Hemophilia A. Additionally, we announced a series of industry firsts on our technology platform, including the demonstration of large, complex gene corrections,” said Brian C. Thomas, Chief Executive Officer of Metagenomi. “Looking ahead, we are planning for additional nonhuman primate data readouts over the course of this year, including 12 month data for our Hemophilia A program, expected in the second half of 2024.”

Recent Program Highlights:

Wholly-owned Pipeline:

In Q4 2023, we achieved integration of a functional Factor VIII gene in nonhuman primates, resulting in clinically relevant circulating levels of Factor VIII up through 4.5 months of follow-up.

We believe this milestone is groundbreaking for the hemophilia community, validates our editing technology, and provides a ready platform for stable delivery of other secreted proteins.

We are progressing towards a Development Candidate nomination for this program, anticipated in the middle of 2024, and plan to present 12-month durability data for Factor VIII expression in the second half of 2024.

Key partnership updates:

Ionis completed target selection of all 4 targets in Wave 1 of our collaboration, nominating the remaining 2 targets in addition to Transthyretin Amyloidosis and Cardiovascular Disease (AGT).

Recent Technology Platform Highlights:

The ability of our metagenomics discovery platform to identify novel enzymes with high activity makes it possible to rapidly develop differentiated technology that surpasses first-generation systems.

Big RIGS (RNA-mediated integration systems):

Using proprietary reverse transcriptases we demonstrated what we believe to be the first-ever targeted integration of >900 bp in human cells with our big RIGS with all-RNA delivery.

We consider this to be a major step forward in the gene editing space, as these systems could be delivered entirely as RNA, compatible with current LNP delivery technologies, and could enable large, targeted exogenous gene integrations.

CAST (CRISPR-associated transposases):

We demonstrated initial preclinical proof-of-capability for our CASTs with a targeted integration of a large DNA template in the genome of mammalian cells. Our CASTs are being developed in order to enable large (>10,000 base pairs), targeted genomic integrations for therapeutic applications.

Base Editing, including ultra-small (SMART) systems:

Our base editors are highly active and progressing towards in vivo therapeutic applications. Using PAM interacting domain engineering, we expanded the genome targetability of our base editors by 5-fold compared to SpCas9 base editors.

We identified a series of novel, highly efficient ultra-small nucleases and demonstrated our ability to engineer these systems into ultra-small base editors and prime editors. We believe our SMART base editors which are as small as 623 amino acids, represent some of the smallest editing systems in the industry. As the size of these systems are well-within the packaging limits of AAV vectors, our SMART base editors could greatly expand both the delivery and targetability options of these systems for disease targets outside the liver.

Recent Corporate Highlights:

Initial public offering:

On February 13, 2024, Metagenomi announced the closing of its initial public offering of 6,250,000 shares of its common stock at a price to the public of $15.00 per share. The aggregate gross proceeds to Metagenomi from the offering were approximately $93.75 million, before deducting underwriting discounts and commissions and offering expenses. Our cash and cash equivalents and available-for-sale marketable securities, including the proceeds from our initial public offering, provide us with a cash runway to support 2 INDs and 2 additional Development Candidate nominations.

Our shares began trading on the Nasdaq Global Select Market on February 9, 2024 under the ticker symbol ​“MGX”.

Strengthened leadership team with key appointments:

Over the course of 2023, we strengthened our leadership team with the appointment of several key executives, focused on driving forward our entry into clinical development, continuing our leadership in gene editing and expanding business operations. These include appointments of Sarah Noonberg, MD, PhD, as Chief Medical Officer, Luis Borges, PhD, as Chief Scientific Officer and Pamela Wapnick, MBA, as Chief Financial Officer.

Full Year 2023 Financial Results:

Cash Position: Cash and cash equivalents and available-for-sale marketable securities were $271.2 million as of December 31, 2023, which does not include the $81.1 million in net proceeds from our IPO completed in February 2024. In addition, cash used to fund our operations was $91.4 million for the year ended December 31, 2023.

R&D Expenses: Research and development (R&D) expenses were $94.4 million for the full year ended December 31, 2023.

G&A Expenses: General and administrative (G&A) expenses were $28.8 million for the full year ended December 31, 2023.
