CAMBRIDGE, Mass., May 05, 2023 (GLOBE NEWSWIRE) -- Editas Medicine, Inc. (Nasdaq: EDIT), a clinical stage genome editing company, today reported business highlights and financial results for the first quarter 2023.

“I am energized by our strong start to the year. We entered 2023 with the objective of accelerating the development of EDIT-301 and positioning Editas as a leader in programable in vivo gene editing. Following on our December EDIT-301 clinical data showing a competitive and potentially differentiated product, we have built considerable momentum with our EDIT-301 program, including dosing and engraftment of the first patient in our EDITHAL trial. We look forward to disclosing the clinical progress of EDIT-301 when we provide a RUBY trial update with safety and efficacy data from multiple patients next month in an oral presentation at the European Hematology Association Congress and in a Company-sponsored webinar. I am pleased with the progress we’ve made against our strategic plan,” commented Gilmore O’Neill, M.B., M.M.Sc., President and Chief Executive Officer, Editas Medicine. “Alongside our newly sharpened strategic focus are our world-class scientists and employees who are committed to our strategic direction and are building on the momentum from our clinical milestones to date and driving execution towards our goals.”
