Metagenomi Presents Data at Scientific Conferences and First Quarter 2024 Financial Results

 

Late breaking presentation at World Federation of Hemophilia (WFH) World Congress on investigational development program in Hemophilia A; development candidate nomination anticipated in mid-year 2024; 12-month non-human primate durability data expected in 2H 2024

 

Presentation at American Society of Gene and Cell Therapy (ASGCT) Annual Meeting demonstrated MGX base editing systems expanded genome targetability by 5-fold compared to SpCas9 Base Editors

 

Presentation at ASGCT demonstrated MGX RNA-mediated integration system (RIGS) shows large gene integration of >900 base pairs in human cells

 

Recovered full rights to wholly-owned base editing and RIGS systems

 

Ended Q1 with cash, cash equivalents and available-for-sale marketable securities of $327.4 million; cash runway anticipated to support anticipated operating plans into 2027

 

 

Emeryville, CA, May 14, 2024 - 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 and business updates for the first quarter ended March 31, 2024.

 

“Our continued execution in the first quarter of 2024 furthers our mission to develop potentially curative genetic medicines by leveraging our extensive genome editing capabilities,” said Brian C. Thomas, Chief Executive Officer and Founder of Metagenomi. “We are excited by the reception of our presentation on our wholly-owned investigational development program in Hemophilia A at the World Federation of Hemophilia World Congress, which demonstrated Factor VIII expression in the therapeutic range in an ongoing NHP study. Furthermore, we see an opportunity to leverage our Hemophilia A program approach as a platform for additional indications requiring large gene integrations. Our updates regarding our base editing systems and RIGS at the American Society of Gene and Cell Therapy Annual Meeting exemplify our leadership in precision genome editing and complex, large genome corrections. In addition, we are thrilled to have recently regained full rights to our base editing and RIGS technology, and we plan to advance these technologies in indications with significant unmet need, such as Alpha-1 antitrypsin deficiency and Wilson’s disease, either on our own or in conjunction with potential partners.”

 

 

Anticipated Milestones in 2024:

---

 

Hemophilia A

We anticipate nominating a development candidate for our wholly-owned lead investigational development program in Hemophilia A in mid-year 2024.

 

We also plan to present 12-month durability data for Factor VIII expression in the ongoing non-human primate study in the second half of 2024. This data represents an important milestone in our pathway towards clinical development and creates a platform for additional large gene integrations.

 

We plan to demonstrate continued technology advancements at key scientific conferences throughout the remainder of 2024.

Corporate Updates:

 

On May 1, 2024, we announced that we regained full global rights to research, develop, manufacture, and commercialize our wholly-owned gene editing technologies, including base editors and RIGS, which were previously subject to exclusive rights granted to ModernaTX, Inc. In addition, we mutually agreed to terminate our collaboration on primary hyperoxaluria type 1 (PH1), and rights to develop the PH1 program, as well as all other rights granted under the collaboration, were returned as part of the termination. This announcement represents a renewed opportunity for us to advance curative genetic medicine through the translation of our broad toolbox of wholly-owned gene editing technologies, as well as a broadened ability to engage with partners in target-specific application of these technologies.

All statements other than statements of historical facts contained in this presentation are forward looking statements, including statements regarding our cash runway, strategy and plans, industry environment, potential growth opportunities, and the therapeutic potential of our programs. The words “believe,” “may,” “will,” “estimate,” “continue,” “anticipate,” “ design,” “expect,” “could,” “plan,” “potential,” “predict,” “seek,” “should,” “would,” or the negative version of these words and similar expressions are intended to identify forward-looking statements. We have based these forward-looking statements on our current expectations and projections about future events and trends that we believe may affect our financial condition, results of operations, strategy, short and long term business operations and objectives, and financial needs. These forward-looking statements are subject to a number of risks, uncertainties and assumptions, including but not limited to, our ability to develop and advance our programs and product candidates, our ability to maintain and establish collaborations or strategic partnerships, our regulatory approvals and filings, and other risks, uncertainties and assumptions identified in our filings with the Securities and Exchange Commission (the “SEC”), including our Form 10-K filed with the SEC on March 27, 2024, our most recently filed Form 10-Q filed with the SEC, and any subsequent filings with the SEC. Moreover, we operate in a very competitive and rapidly changing environment and it is not possible for our management to predict all risks, nor can we assess the impact of all factors on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements we may make. In light of these risks, uncertainties and assumptions, the forward-looking statements and circumstances discussed in this presentation may not occur and actual results could differ materially and adversely from those anticipated or implied in the forward-looking statements. You should not rely upon forward-looking statements as predictions of future events. Although we believe that the expectations reflected in the forward-looking statements are reasonable, we cannot guarantee that the future results, levels of activity, performance or events and circumstances reflected in the forward-looking statements will be achieved or occur. Moreover, except as required by law, neither we nor any other person assumes responsibility for the accuracy and completeness of the forward-looking statements. We undertake no obligation to update publicly any forward-looking statements for any reason after the date of this presentation to conform these statements to actual results or to changes in our expectations, unless required by law. This presentation contains estimates and other information concerning our industry, our business and the markets for our products Information that is based on estimates, market research or similar methodologies is inherently subject to uncertainties, and actual events or circumstances may differ materially from events and circumstances that are assumed in this information. Unless otherwise expressly stated, we obtained this industry, business, market and other data from our own internal estimates and research as well as from reports, research surveys, studies and similar data prepared by market research firms and other third parties, industry, medical and general publications, government data and similar sources. These sources include government and industry sources. Industry publications and surveys generally state that the information contained therein has been obtained from sources believed to be reliable. Although we believe the industry and market data to be reliable as of the date of this presentation, this information could prove to be inaccurate. Industry and market data could be wrong because of the method by which sources obtained their data and because information cannot always be verified with complete certainty due to the limits on the availability and reliability of raw data, the voluntary nature of the data gathering process and other limitations and uncertainties. While we believe our internal company estimates and research as to such matters is reliable and the market definitions are appropriate, neither such research nor these definitions have been verified by any independent source and no reliance should be placed on should be made on any information or statements made in this presentation relating to or based on such internal estimates and research. 2 Non-Confidential Investor Overview
