In vivo preclinical proof-of-concept data presented at AHA and ESGCT demonstrating >90% LDL-C reduction in non-human primates supports EDIT-401’s potential as a best-in-class, one-time therapy

Company on track to submit IND/CTA for EDIT-401 by mid-2026 and achieve initial human proof-of-concept data by year-end 2026

Extended cash runway into the third quarter of 2027, enabling progression of EDIT-401 beyond initial human proof-of-concept data

CAMBRIDGE, Mass., Nov. 10, 2025 (GLOBE NEWSWIRE) -- Editas Medicine, Inc. (Nasdaq: EDIT), a pioneering gene editing company focused on developing transformative medicines for serious diseases, today reported financial results for the third quarter 2025 and provided business updates.

“We are incredibly excited by the progress we made in the third quarter advancing our lead in vivo development candidate, EDIT-401, an experimental, potential best-in-class, one-time therapy designed to significantly reduce LDL cholesterol levels. We recently presented data at AHA and ESGCT demonstrating the ability of EDIT-401 to reduce mean LDL cholesterol levels by over 90 percent in non-human primates,” said Gilmore O’Neill, M.B., M.M.Sc., President and Chief Executive Officer of Editas Medicine. “In addition, we have extended our cash runway into the third quarter of 2027 and remain on track to submit an investigational new drug or clinical trial application for EDIT-401 by mid-2026, with the goal of achieving in vivo human proof-of-concept data by the end of 2026.”

Recent Achievements and Outlook

EDIT-401

• In September, the Company announced the selection of its lead in vivo development candidate, EDIT-401, an experimental, potential best-in-class, one-time therapy designed to significantly reduce LDL cholesterol (LDL-C) levels.
• In October and November, the Company presented preclinical data at the 32nd Annual European Society of Gene and Cell Therapy (ESGCT) Congress and the American Heart Association (AHA) Scientific Sessions 2025. Key findings included:
  • ≥90% LDL-C reduction in non-human primates (NHPs) achieved within 48 hours of a single dose of EDIT-401; ≥90% LDL-C reduction in mice with high baseline LDL-C and reduced LDLR function
  • The ≥90% reduction in LDL-C was achieved with ≥6-fold mean increase in LDLR protein in the NHP liver, requiring only a moderate level of functional editing of LDLR alleles (~10-40%) in the liver
  • LDL-C reduction was maintained in mouse models in a three-month study, demonstrating the durability of effect
• Editas is on track to submit an investigational new drug (IND) or clinical trial application (CTA) for EDIT-401 by mid-2026, and to achieve initial in vivo human proof-of-concept data for EDIT-401 by the end of 2026.

Other Corporate Highlights

• The Company extended its cash runway into the third quarter of 2027 with proceeds from sales of its common stock under its at-the-market (“ATM”) facility and continued financial discipline.

Third Quarter 2025 Financial Results
Cash, cash equivalents, and marketable securities as of September 30, 2025 were $165.6 million compared to $269.9 million as of December 31, 2024. The Company expects that the existing cash, cash equivalents, marketable securities, together with $17.3 million of proceeds from sales of shares of common stock under its ATM facility after September 30, 2025, and the retained portions of the payments payable under its license agreement with Vertex Pharmaceuticals, will enable the Company to fund its operating expenses and capital expenditure requirements into the third quarter of 2027.

• For the three months ended September 30, 2025, the company raised $17.8 million of gross equity proceeds from its ATM facility.
  

Third Quarter 2025

• For the three months ended September 30, 2025, net loss attributable to common stockholders was $25.1 million, or $0.28 per share, compared to net loss of $62.1 million, or $0.75 per share, for the same period in 2024.
• Collaboration and other research and development revenues increased to $7.5 million for the three months ended September 30, 2025, compared to $0.1 million for the same period in 2024. The increase is primarily attributable to the recognition of revenue related to a milestone achieved under the Company’s collaboration agreement with BMS in the third quarter of 2025.
• Research and development expenses decreased by $27.9 million to $19.8 million for the three months ended September 30, 2025, compared to $47.6 million for the same period in 2024. The decrease is primarily related to reduced clinical and manufacturing costs related to discontinuation of the clinical development of the Company’s reni-cel program initiated in December 2024, partially offset by costs attributable to in vivo research and discovery.
  
  
• General and administrative expenses decreased by $5.8 million to $12.3 million for the three months ended September 30, 2025, compared to $18.1 million for the same period in 2024. The decrease is primarily attributable to a reduction in employee-related expenses related to reduced headcount associated with the reduction in workforce in connection with the discontinuation of the clinical development of the Company’s reni-cel program initiated in December 2024.
  
• There were no restructuring and impairment charges recognized for the three months ended September 30, 2025, and 2024. The restructuring and impairment charges for the nine months ended September 30, 2025 were related to the discontinuation of the clinical development of the Company’s reni-cel program initiated in December 2024, the related workforce reduction, associated impairment charges for laboratory and manufacturing equipment related to the reni-cel program, and the acceleration in expense due to changes in useful life estimates for leasehold improvements, software and a right of use asset associated with the Company’s reni-cel program.
