Item 7.01 Regulation FD Disclosure.
On May 14, 2026, Editas Medicine, Inc. (the “Company”) issued a press release titled “Editas Medicine Reports New Preclinical Data Demonstrating Progress of EDIT-401 as Potential Treatment for Hyperlipidemia at the American Society of Gene and Cell Therapy 2026 Annual Meeting,” a copy of which is furnished as Exhibit 99.1 hereto.
The information in this Item 7.01, including Exhibit 99.1 attached hereto, is intended to be furnished and shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise subject to the liabilities of that section, nor shall it be deemed incorporated by reference in any filing under the Securities Act of 1933, as amended, or the Exchange Act, except as expressly set forth by specific reference in such filing.
Item 8.01 Other Events.
On May 14, 2026, at the 2026 Annual Meeting of the American Society of Gene and Cell Therapy (“ASGCT”), the Company reported new preclinical data supporting the continued advancement of the Company’s lead in vivo development candidate, EDIT-401, and its potential as a one-time treatment for hyperlipidemia, as well as the broader potential of the Company’s differentiated upregulation strategy. The Company reported that a single dose of EDIT-401 achieved 90% or greater mean LDL cholesterol (“LDL-C”) reduction across all dose groups in non-human primates. This reduction was achieved with only moderate levels (10-40%) of functional editing of LDLR alleles and a six or greater-fold mean increase in hepatic LDLR protein. LDL-C lowering was rapid and remained durable across evaluated dose levels (1.5 mg/kg-3.0 mg/kg) through approximately six months. The data demonstrated a promising preclinical safety profile with no adverse clinical observations at the therapeutically relevant dose (1.5 mg/kg). The highest delivery of EDIT-401 was observed in the hepatocytes as compared to other non-target tissues with undetectable oocyte delivery. The Company also reported at ASGCT that data evaluating pharmacokinetics and pharmacodynamics of a single dose of EDIT-401(mu) across multiple dose levels in heterozygous Ldlr loss-of-function mice and wildtype mice support that dose adjustments may not be needed to achieve LDL-C lowering in heterozygous familial hypercholesterolemia (HeFH) patients.

Exhibit 99.1
Editas Medicine Reports New Preclinical Data Demonstrating Progress of EDIT-401 as Potential Treatment for Hyperlipidemia at the American Society of Gene and Cell Therapy 2026 Annual Meeting
New data demonstrate promising preclinical safety profile and durable LDL-C lowering of ≥90% with single dose of EDIT-401 in non-human primates through ~6 months
CAMBRIDGE, Mass., May 14, 2026 – Editas Medicine, Inc. (Nasdaq: EDIT), a pioneering gene editing company developing transformative medicines for serious diseases, shared new preclinical data supporting the continued advancement of Editas’ lead in vivo development candidate, EDIT-401, and its potential as a one-time treatment for hyperlipidemia, as well as the broader potential of the Company’s differentiated upregulation strategy. The data is being presented this week at the 2026 Annual Meeting of the American Society of Gene and Cell Therapy (ASGCT) in Boston, including one oral presentation and two poster presentations, as well as one oral presentation at TIDES USA 2026: Oligonucleotide and Peptide Therapeutics Conference.
Key EDIT-401 data presented include:
•In an oral presentation at ASGCT, Editas reported that a single dose of EDIT-401 achieved ≥90 percent mean LDL-C reduction across all dose groups in non-human primates (NHPs).
o≥90 percent mean LDL-C reduction was achieved with only moderate levels (10-40 percent) of functional editing of LDLR alleles and ≥6-fold mean increase in hepatic LDLR protein.
oLDL-C lowering was rapid and remained durable across evaluated dose levels (1.5 mg/kg-3.0 mg/kg) through ~6 months.
oPromising preclinical safety profile with no adverse clinical observations at therapeutically relevant dose (1.5 mg/kg).
oThe highest delivery of EDIT-401 was observed in the hepatocytes as compared to other non-target tissues with undetectable oocyte delivery.
•In an oral presentation at TIDES, Editas presented data demonstrating EDIT-401 dose-dependent LDL-C reduction in NHPs.
•In a poster presentation at ASGCT, Editas reported that data evaluating pharmacokinetics and pharmacodynamics of a single dose of EDIT-401(mu) across multiple dose levels in heterozygous Ldlr loss-of-function mice and wildtype mice support that dose adjustments may not be needed to achieve LDL-C lowering in Heterozygous Familial Hypercholesterolemia (HeFH) patients.
Additional in vivo upregulation findings from a poster presentation at ASGCT include:
•Data support leveraging DNA large language prediction models (DNA-LLM) to accelerate and streamline the pursuit of gene editing-based strategies designed to mitigate disease through augmentation of alternate or compensatory pathways and further highlight the broader potential of Editas’ in vivo gene upregulation platform.
“These new EDIT-401 preclinical data, including durability of LDL-C reduction across a range of doses through ~6 months demonstrated in NHPs, strengthen our confidence in EDIT-401 as a potential one-time treatment to deliver meaningful and durable LDL-C lowering and support its continued advancement toward first-in-human clinical development,” said Linda C. Burkly, Ph.D., Executive Vice President and Chief Scientific Officer, Editas Medicine. “Further, the data presented also highlight the broader potential and differentiation of our upregulation strategy to generate new medicines across multiple disease areas.”
The presentation details are listed below. Abstracts can be accessed on the ASGCT website, and the presentations will be posted on the Editas Medicine website during the conferences.
