Editas Medicine to Present Clinical Data from the RUBY and EdiTHAL Trials of Reni-cel at the European Hematology Association 2024 Congress in June


CAMBRIDGE, Mass., May 14, 2024 (GLOBE NEWSWIRE) -- Editas Medicine, Inc. (Nasdaq: EDIT), a clinical-stage gene editing company, today announced that two abstracts, including one oral presentation and one poster presentation, detailing clinical data from the RUBY and EdiTHAL trials of renizgamglogene autogedtemcel (reni-cel) have been accepted for presentation at the European Hematology Association (EHA) Hybrid Congress being held June 13-16, 2024, in Madrid, Spain, and via livestream.

Clinical data from patients treated in the Phase 1/2/3 RUBY trial of reni-cel in patients with severe sickle cell disease and in the Phase 1/2 EdiTHAL trial of reni-cel in patients with transfusion-dependent beta thalassemia will be shared, including:

  • RUBY trial, Abstract #S285, oral presentation on Saturday, June 15:
    • Clinical data on at least 18 patients, with 2-21 months follow-up.
    • Efficacy data, including total hemoglobin, fetal hemoglobin, and vaso-occlusive events (VOEs).
    • Safety data, including neutrophil and platelet engraftment.
  • EdiTHAL trial, Abstract #P1476, poster presentation on Friday, June 14:
    • Clinical data on seven patients, with 4-12 months follow-up.
    • Efficacy data, including total hemoglobin, fetal hemoglobin, and transfusion independence.
    • Safety data, including neutrophil and platelet engraftment.

“We are making significant progress with the continued development of reni-cel, and we look forward to sharing clinical data, including longer follow up of the dosed patients from the RUBY and EdiTHAL trials next month at the European Hematology Association Congress. These data further support our belief that reni-cel has the potential to be a clinically differentiated, one-time, durable medicine that can provide life-changing clinical benefits to patients,” said Baisong Mei, M.D., Ph.D., 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.”

The abstracts can be accessed on the EHA website.

Reni-cel 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). In addition to the clinical data update from the RUBY trial and the EdiTHAL trial at EHA next month, the Company will present a further clinical update from both trials by year-end.


About renizgamglogene autogedtemcel (reni-cel)
Reni-cel, formerly known as 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). Reni-cel 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 AsCas12a, a novel, proprietary, highly efficient, and specific gene editing nuclease. Red blood cells derived from reni-cel 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 reni-cel in patients with severe sickle cell disease. Enrolled patients will receive a single administration of reni-cel. The RUBY trial marks the first time AsCas12a was used to successfully edit human cells in a clinical trial. Additional details are available on www.clinicaltrials.gov (NCT04853576).

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 reni-cel in patients with transfusion-dependent beta thalassemia. Patients will receive a single administration of reni-cel. Additional details are available on www.clinicaltrials.gov (NCT05444894).
