Focus on in vivo CRISPR-edited medicines based on Editas researchers’ recent scientific progress in multiple tissues: Achieved pre-clinical in vivo proof of concept of high level HBG1/2 promoter editing and HbF induction in a humanized mouse model for treatment of sickle cell disease and beta thalassemia with a single dose of an HSC-targeted lipid nanoparticle (tLNP) formulationAchieved in vivo proof of concept of high efficiency editing in the liver in non-human primates Ending development of reni-cel after extensive search did not yield a commercial partner The Company will work closely with the clinical trial sites, regulators, and other parties to determine the path forward for patients enrolled in the RUBY and EdiTHAL trials Initiating cost savings measures and reduction in headcount to align workforce and resources to in vivo pipeline, extending cash runway into Q2 2027Conference call and webcast today at 5:00 p.m. ET CAMBRIDGE, Mass., Dec. 12, 2024 (GLOBE NEWSWIRE) -- Editas Medicine, Inc. (Nasdaq: EDIT), a leading gene editing company, today announced a critical pivot to optimize its cost structure, extend its cash runway into Q2 2027, and position the Company to accelerate its intent to achieve in vivo human proof of concept in approximately two years. “Recent scientific breakthroughs by the Editas team have convinced us that the timelines around the near-term viability of in vivo CRISPR-edited medicines have accelerated meaningfully. Two years ago, we laid out our strategy and objective to become a leader in in vivo programmable gene editing. Based on these advances, we are transitioning to a fully in vivo company. We believe the ability to provide in vivo gene editing that functions via gene upregulation across tissues holds the potential to significantly expand the addressable therapeutic possibilities for CRISPR-based gene editing and uniquely position Editas to be a leader in the field moving forward,” said Gilmore O’Neill, M.B., M.M.Sc., President and Chief Executive Officer, Editas Medicine. The Company transition follows the recent in vivo pre-clinical proof of concept in multiple tissues: Hematopoietic Stem Cells (HSCs): Editas achieved ~40% editing of the HBG1/2 promoter site after using a novel, Editas-proprietary targeted lipid nanoparticle (tLNP) for extrahepatic tissue delivery to deliver a single dose of its clinically validated Cas12a editing machinery directly to human hematopoietic stem cells (HSCs) in mice engrafted with human HSCs.1HBG1/2 biology has been validated and derisked in patients with reni-cel in the RUBY trial.The editing in HSCs with the Company’s proprietary tLNP formulation resulted in the meaningful functional outcome of HbF induction, indicated by the presence of HbF expressing human red blood cells (on average 20%) that populate in the host by one month. Liver: The Company achieved in vivo proof of concept of high efficiency editing in the liver in non-human primates under its collaboration with Genevant. The Company intends to share pre-clinical data and further development timelines from these programs in the first quarter of 2025. In vivo HSC editing success is expected to enable extrahepatic tissues/cell types targeting beyond HSCs and demonstrates the potential of “plug ‘n play” in an in vivo extrahepatic LNP platform. The Company’s upregulation capability additionally enables a differentiated strategy for liver targets for diseases with high unmet need and first-in-class opportunities. In connection with Editas Medicine’s transition to an in vivo company, the Company initiated a reduction in headcount that will eliminate approximately 65% of its workforce over the next six months. As part of this reduction in force, several members of the Editas management team will depart the company over the next six months, including Baisong Mei, M.D., Ph.D., the Company’s Chief Medical Officer. Additionally, Emma Reeve and Meeta Chatterjee, Ph.D. are resigning from the Board of Directors, effective December 31, 2024. Jessica Hopfield, Ph.D., has been named Chair of the Board, effective December 31, 2024. Dr. O’Neill added, “We want to extend our deepest appreciation to patients, investigators, clinical sites staff, and our employees who have shown tremendous dedication and commitment to developing a potentially transformational medicine like reni-cel. We also want to express specific gratitude to the patients in our clinical trials and their caregivers whose dedication to disease research for their community makes us even more committed to accelerating our efforts towards an in vivo program for sickle cell disease and beta thalassemia.” Conference Call The Editas Medicine management team will host a conference call and webcast today at 5:00 p.m. ET. To access the call, please dial 1-877-407-0989 (domestic) or +1 201-389-0921 (international) and ask for the Editas Medicine conference call. A live webcast of the call will also be available on the Investors section of the Editas Medicine website at www.editasmedicine.com, and a replay will be available approximately two hours after its completion.

The words ‘‘anticipate,’’ ‘‘believe,’’ ‘‘continue,’’ ‘‘could,’’ ‘‘estimate,’’ ‘‘expect,’’ ‘‘intend,’’ ‘‘may,’’ ‘‘plan,’’ ‘‘potential,’’ ‘‘predict,’’ ‘‘project,’’ ‘‘target,’’ ‘‘should,’’ ‘‘would,’’ and similar expressions are intended to identify forward-looking statements, although not all forward-looking statements contain these identifying words. Forward-looking statements in this press release include statements regarding the Company’s transition to a fully in vivo company, the intention to achieve human proof of concept in approximately two years, and the potential success of its in vivo gene editing programs, the timing for releasing additional pre-clinical data, the anticipated effects, including potential cost savings, of the Company’s decision to discontinue development of reni-cel and initiate the related reduction in headcount, the scope and timing of the reduction in headcount, and the expected extension of the Company’s cash runway. The Company may not actually achieve the plans, intentions, or expectations disclosed in these forward-looking statements, and you should not place undue reliance on these forward-looking statements. Actual results or events could differ materially from the plans, intentions and expectations disclosed in these forward-looking statements as a result of various important factors, including: uncertainties inherent in the initiation and completion of preclinical studies; availability and timing of results from preclinical studies; expectations for regulatory approvals to conduct trials; availability of funding sufficient for the Company’s foreseeable and unforeseeable operating expenses and capital expenditure requirements; and that the decision to discontinue clinical development of reni-cel and the related reduction in headcount may have unexpected consequences or not result in the expected cost savings.
