Item 7.01 Regulation FD Disclosure.
On June 12, 2025, Editas Medicine, Inc. (the “Company”) issued a press release titled “Editas Medicine Reports Proprietary Targeted Lipid Nanoparticle Delivery in Non-Human Primates Enables In Vivo HBG1/2 Promoter Editing for Sickle Cell Disease and Beta Thalassemia at the European Hematology Association 2025 Congress in June,” 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 June 12, 2025, the Company announced new in vivo data demonstrating therapeutically relevant levels of HBG1/2 promoter editing in hematopoietic stem cells (“HSCs”) with a single dose of proprietary targeted lipid nanoparticle (“tLNP”) in non-human primates (“NHPs”).
In this study, the Company’s proprietary tLNP formulation delivered HBG1/2 promoter editing cargo to HSCs in NHPs. Latest data from this ongoing NHP study showed that at five months a single intravenous administration of Editas’ tLNP resulted in mean on-target editing levels in the HBG1/2 promoter region of 58% in HSCs, exceeding the predicted editing threshold of ≥25% required for therapeutic benefit. In addition to achieving therapeutically relevant editing levels, the biodistribution data in NHPs with the Company’s tLNP continue to show significant de-targeting of the liver in contrast to standard LNPs.
