Company to host a webinar to discuss EDIT-301 clinical data on Monday, December 11, at 1:00 p.m. ET
Dr. Rabi Hanna from Cleveland Clinic Children’s to present EDIT-301 clinical data at ASH on Monday, December 11
CAMBRIDGE, Mass., Nov. 02, 2023 (GLOBE NEWSWIRE) -- Editas Medicine, Inc. (Nasdaq: EDIT), a clinical-stage genome editing company, today announced that a scientific abstract detailing safety and efficacy clinical data from the RUBY trial of EDIT-301 in patients with severe sickle cell disease and from the EdiTHAL trial of EDIT-301 in patients with transfusion-dependent beta thalassemia has been accepted for a poster presentation at the 65th American Society of Hematology (ASH) Annual Meeting and Exposition being held December 9-12, 2023, in San Diego, CA, and online.
Editas Medicine will also host a Company-sponsored webinar on Monday, December 11, at 1:00 p.m. ET to discuss the RUBY and EdiTHAL clinical data.
Key data from patients treated in the RUBY trial and in the EdiTHAL trial will be shared, including:
- RUBY
- Clinical data on 11 patients, including two patients with at least 12 months follow-up and an additional four patients with at least five months follow-up.
- Efficacy data, including total hemoglobin, fetal hemoglobin, and vaso-occlusive events, or VOEs.
- Safety data, including neutrophil and platelet engraftment.
- EdiTHAL
- Clinical data on six patients, including at least five months data from the first two patients treated.
- Efficacy data, including total hemoglobin and fetal hemoglobin.
- Safety data, including neutrophil and platelet engraftment.
“We are making significant progress with EDIT-301, and we look forward to sharing clinical data, including additional data collected since the submission of the abstract, from the RUBY and EdiTHAL trials next month at the American Society of Hematology Annual Meeting and in a Company-sponsored webinar. This data further supports our belief that EDIT-301 has the potential to be a clinically differentiated, one-time, durable medicine that can provide life-changing clinical benefits to patients,” Baisong Mei, M.D., Ph.D., Senior Vice President and Chief Medical Officer, Editas Medicine. “I would like to thank the participants, their families and caregivers, clinicians, and colleagues at collaborating institutions that contribute to the RUBY and EdiTHAL trials.”

EDIT-301 is currently being investigated in a clinical study in patients with severe sickle cell disease (RUBY trial, NCT04853576) and transfusion-dependent beta thalassemia (EDITHAL trial, NCT05444894).
About Sickle Cell Disease
Sickle cell disease is an inherited blood disorder caused by a mutation in the beta-globin gene that leads to polymerization of the sickle hemoglobin (HbS). In sickle cell disease, the red blood cells are misshapen in a sickle shape instead of a typical disc shape. The abnormal shape causes the red blood cells to have shortened lifespan and to block blood flow causing anemia, pain crises, organ failure, and early death. There are an estimated 100,000 people in the United States currently living with sickle cell disease. Higher levels of fetal hemoglobin (HbF) inhibit HbS polymerization, thus reducing the manifestation of sickling.
About EDIT-301
EDIT-301 is an experimental gene editing medicine under investigation for the treatment of severe sickle cell disease (SCD) and transfusion-dependent beta thalassemia (TDT). EDIT-301 consists of patient-derived CD34+ hematopoietic stem and progenitor cells edited at the gamma globin gene (HBG1 and HBG2) promoters, where naturally occurring fetal hemoglobin (HbF) inducing mutations reside, by a highly specific and efficient proprietary engineered AsCas12a nuclease. Red blood cells derived from EDIT-301 CD34+ cells demonstrate a sustained increase in fetal hemoglobin production, which has the potential to provide a one-time, durable treatment benefit for people living with severe SCD and TDT.
About the RUBY Trial
The RUBY trial is a single-arm, open-label, multi-center Phase 1/2 study designed to assess the safety and efficacy of EDIT-301 in patients with severe sickle cell disease. Enrolled patients will receive a single administration of EDIT-301. Additional details are available on (NCT#04853576).
About the EdiTHAL Trial
The EdiTHAL trial is a single-arm, open label, multi-center Phase 1/2 study designed to assess the safety and efficacy of EDIT-301 in patients with transfusion-dependent beta thalassemia. Patients will receive a single administration of EDIT-301. Additional details are available on (NCT# 05444894).
