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
Achieved 58% mean editing at five months after a single dose using high efficiency HSC delivery, demonstrating therapeutically relevant editing levels using a clinically validated strategy. Achievement supports development of a novel, in vivo approach to treating sickle cell disease and beta thalassemia. CAMBRIDGE, Mass., June 12, 2025 (GLOBE NEWSWIRE) -- Editas Medicine, Inc. (Nasdaq: EDIT), a pioneering gene editing company, today shared 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). This clinically validated approach targeting HBG1/2 promoters to upregulate fetal hemoglobin (HbF) is in pre-clinical development as a potential transformative in vivo gene editing medicine for the treatment of sickle cell disease and beta thalassemia. The Company reported these data in a presentation available today and will detail the data in a poster session on Saturday, June 14th 6:30 - 7:30 p.m. CEST (12:30 – 1:30 p.m. EDT) at the European Hematology Association (EHA) 2025 Congress in Milan, Italy. 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: well 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 Editas' tLNP continue to show significant de-targeting of the liver in contrast to standard LNPs. 'These data from our in vivo HSC program confirm our ability to achieve high efficiency delivery, therapeutically relevant editing levels and favorable biodistribution in NHPs. These data validate the further development of Editas' proprietary HSC-tLNP for editing of the HBG1/2 promoters for the treatment of sickle cell disease and beta thalassemia,' said Linda C. Burkly, Ph.D., Executive Vice President and Chief Scientific Officer, Editas Medicine. Editas Medicine's in vivo HSC program targets HBG1/2 promoters to mimic naturally occurring mechanisms of hereditary persistence of fetal hemoglobin (HPFH) and utilizes proprietary AsCas12a to edit with high efficiency and minimize off-target editing. Editing the HBG1/2 promoters with AsCas12a with the investigational medicine reni-cel led to robust increases in HbF and total hemoglobin (Hb) in clinical trials. The presentation details are listed below. Abstracts can be accessed on the EHA website, and the presentation will be posted on the Editas Medicine website during the conference.

Editas Medicine Reports New In Vivo Data Highlighting the Potential of Editas' Gene Upregulation Strategy in HSCs at the American Society of Gene and Cell Therapy Annual Meeting
Data demonstrate therapeutically relevant editing levels using a clinically validated strategy, supporting its development as a novel, in vivo approach to treating sickle cell disease and beta thalassemia CAMBRIDGE, Mass., May 14, 2025 (GLOBE NEWSWIRE) -- Editas Medicine, Inc. (Nasdaq: EDIT), a pioneering gene editing company, today shared 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 humanized mice and non-human primates (NHPs). This clinically validated approach targeting HBG1/2 promoters to upregulate fetal hemoglobin (HbF) is in pre-clinical development as a potential transformative in vivo gene editing medicine for the treatment of sickle cell disease and beta thalassemia. The Company reported these data in a presentation available today and will detail the data in an oral presentation today at 1:30 p.m. CT/2:30 p.m. ET at the 28th Annual Meeting of the American Society of Gene and Cell Therapy (ASGCT) in New Orleans, LA, and virtually. In these studies, the Company's proprietary tLNP formulation delivered HBG1/2 promoter editing cargo to HSPCs and/or HSCs in humanized mice (mice engrafted with human CD34+ cells) and in NHPs. In an ongoing NHP study, administration of a single intravenous dose of Editas Medicine's proprietary tLNP demonstrated high efficiency HSC delivery and achieved up to 47% HBG1/2 editing levels. In a study with humanized mice, administration of a single dose achieved 48% editing of HBG1/2 in long-term HSCs. Both studies exceeded the predicted editing threshold of ≥25% required for therapeutic benefit. In addition to achieving therapeutically relevant editing levels, preliminary biodistribution data in NHPs with Editas' tLNP shows significant de-targeting of the liver in contrast to standard LNPs. 'These findings are very encouraging and further support our approach to developing a potentially first- and best-in-class in vivo gene edited medicine for the treatment of sickle cell disease and beta thalassemia,' said Linda C. Burkly, Ph.D., Executive Vice President and Chief Scientific Officer, Editas Medicine. 'We believe that translating these preclinical results to the clinic will address the continuing significant unmet need for a transformative gene edited medicine with the potential to improve the lives of people living with sickle cell disease and beta-thalassemia around the world.' Editas Medicine's in vivo HSC program targets HBG1/2 promoters to mimic naturally occurring mechanisms of hereditary persistence of fetal hemoglobin (HPFH) and utilizes proprietary AsCas12a to edit with high efficiency and minimize off-target editing. Editing the HBG1/2 promoters with AsCas12a with the investigational medicine reni-cel led to robust increases in fetal hemoglobin (HbF) and total hemoglobin (Hb) in clinical trials.
