Key Financial Figures

Filing Documents

01 Regulation FD Disclosure

Item 7.01 Regulation FD Disclosure. On October 9, 2025, Editas Medicine, Inc. (the "Company") issued a press release titled "Editas Medicine Reports In Vivo Proof-of-Concept Data for EDIT-401 at the European Society of Gene and Cell Therapy (ESGCT) 32nd Annual Congress," 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.

01 Other Events

Item 8.01 Other Events. On October 9, 2025, at the 32nd Annual European Society of Gene and Cell Therapy Congress, the Company reported in vivo preclinical proof-of-concept data for EDIT-401, an experimental, potential best-in-class, one-time therapy to significantly reduce LDL-cholesterol ("LDL-C") through upregulation of the LDL receptor ("LDLR"). In preclinical studies in non-human primates, EDIT-401 achieved LDL-C reductions in non-human primates equal to or exceeding 90% within 48 hours of a single dose. EDIT-401 also achieved LDL-C reductions equal to or exceeding 90% in mice with high baseline LDL-C and reduced LDLR function. LDL-C reductions were maintained in mouse models in a three-month study. The Company's EDIT-401 therapeutic strategy includes the use of a CRISPR/Cas9 nuclease and dual guide RNAs with lipid nanoparticle delivery to disrupt negative regulatory elements in the 3' UTR, increasing mRNA stability enabling potent LDLR upregulation. The Company observed that the LDL-C reductions following EDIT-401 treatment were achieved with an at least six-fold mean increase in LDLR protein in the non-human primate liver, requiring only a moderate level of functional editing of LDLR alleles.
