CAMBRIDGE, Mass., May 08, 2024 (GLOBE NEWSWIRE) -- Editas Medicine, Inc. (Nasdaq: EDIT), a clinical-stage gene editing company, today reported financial results for the first quarter 2024 and provided business updates.

“We made significant progress in all three pillars of our strategy this quarter, including reni-cel, in vivo, and business development, including intellectual property,” commented Gilmore O’Neill, M.B., M.M.Sc., President and Chief Executive Officer, Editas Medicine. “We entered 2024 with great momentum, and I am proud of the Editas team’s significant progress toward becoming a commercial-stage company and on developing clinically differentiated, transformational medicines for people living with serious, previously untreatable diseases.”

Recent Achievements and Outlook

Ex Vivo Hemoglobinopathies

• Reni-cel (renizgamglogene autogedtemcel, previously EDIT-301) for Severe Sickle Cell Disease (SCD)
  • The Company has completed enrollment of the adult cohort of the Phase 1/2/3 RUBY trial for SCD and continues to dose patients.
  • The Company has enrolled multiple patients in the adolescent cohort in the RUBY trial.
  • The Company remains on-track to present a substantive clinical data set of sickle cell patients with considerable clinical follow-up in the RUBY trial in mid-2024 and further data by year-end 2024.

• Reni-cel for Transfusion-dependent Beta Thalassemia (TDT)
  • The Company continues to enroll and dose patients in the EdiTHAL trial for TDT.
  • The Company remains on-track to present additional clinical data from the EdiTHAL trial in mid-2024 and further data by year-end 2024.

In Vivo Medicines

• The Company is presenting pre-clinical data later this week to support its development of transformative in vivo gene editing medicines at the American Society of Gene and Cell Therapy (ASGCT) 27^th Annual Meeting on May 9 and 10. Presentations include:
  • Oral presentation of in vivo pre-clinical data from mouse studies using lipid nanoparticle (LNP)-mediated delivery of an optimized guide RNA (gRNA) and engineered AsCas12a messenger RNA (mRNA).
  • Pre-clinical data demonstrating AsCas12a gRNA modifications that enable high-potency gene editing in multiple cell types, including in the liver, and improve gene editing outcomes in vivo, enabling the development of in vivo gene editing medicines.
  • Research on identifying potent large serine recombinases (LSRs) as a foundation to develop novel in vivo gene editing technologies for whole gene knock-in, expanding potential in vivo gene editing targets for developing medicines.
• The Company is on track to establish in vivo preclinical proof-of-concept for an undisclosed indication by year-end.

Other Corporate Highlights

Business Development

• In March 2024, Editas Medicine and Bristol Myers Squibb (NYSE: BMY) signed a two-year extension to the collaboration under which the parties may research, develop, and commercialize autologous and allogeneic alpha-beta T cell medicines for the treatment of cancer and autoimmune diseases. The extension also has options to further extend the collaboration for up to an additional two years.

Intellectual Property

• Oral Arguments held in CRISPR patent interference
  On May 7, 2024, oral arguments were held before the U.S. Court of Appeals for the Federal Circuit (CAFC) regarding an appeal of the Patent Trial and Appeal Board’s (PTAB’s) previous decision favoring Broad Institute (Broad) in the U.S. patent interference involving specific patents for CRISPR/Cas9 editing in human cells between the University of California, the University of Vienna, and Emmanuelle Charpentier (collectively, CVC) and Broad. A decision on the case is expected in the second half of 2024.

Leadership

• Gregory Whitehead named Executive Vice President and Chief Technical and Quality Officer
  Mr. Whitehead joins the executive leadership team as Chief Technical and Quality Officer (CTQO), responsible for leading the Technical Development, Technical Operations, and Quality departments as the Company advances its gene editing medicines towards biologics license applications (BLAs). Mr. Whitehead has more than 25 years of experience in the biotech industry and extensive cell and gene therapy clinical and commercial development expertise. Prior to his current role, Mr. Whitehead served as Senior Vice President of Quality at Editas Medicine. Before joining Editas Medicine, Mr. Whitehead served as Chief Quality Officer at Rubius Therapeutics, establishing quality capabilities to support first-in-human clinical trials for genetically engineered red blood cells. Earlier in his career, he served as Vice President, Quality at bluebird bio. During his tenure at bluebird bio, Mr. Whitehead scaled the organization in support of multiple gene therapy clinical trials and commercial launch in the U.S. and Europe.

Publications

• The New England Journal of Medicine published the findings from the Phase 1/2 BRILLIANCE trial of EDIT-101, on May 6.
  • The BRILLIANCE trial was the first in vivo CRISPR gene editing study in humans, and the study demonstrated clinical proof of concept in treatment of a rare inherited blindness, Leber Congenital Amaurosis 10, with a favorable safety profile, and preliminary efficacy signals for patients.

First Quarter 2024 Financial Results

Cash, cash equivalents, and marketable securities as of March 31, 2024, were $376.8 million compared to $427.1 million as of December 31, 2023. The Company expects the existing cash, cash equivalents, and marketable securities together with the near-term annual license fees and the contingent upfront payment payable under its license agreement with Vertex Pharmaceuticals, Incorporated, to fund operating expenses and capital expenditures into 2026.

First Quarter 2024

• For the three months ended March 31, 2024, net loss attributable to common stockholders was $62.0 million, or $0.76 per share, compared to net loss of $49.0 million, or $0.71 per share, for the same period in 2023.
  
  
• Collaboration and other research and development revenues decreased to $1.1 million for the three months ended March 31, 2024, compared to $9.9 million for the same period in 2023. The decrease relates to the one-time sale in January 2023 of the Company's wholly owned oncology assets and related licenses.
  
  
• Research and development expenses increased by $11.0 million to $48.8 million for the three months ended March 31, 2024, compared to $37.8 million for the same period in 2023. The increase is primarily attributable to sublicense and license payments as well as clinical and manufacturing costs related to the continued progression of the Company's reni-cel program.
  
  
• General and administrative expenses decreased by $3.7 million to $19.3 million for the three months ended March 31, 2024, compared to $23.0 million for the same period in 2023. The decrease is primarily attributable to one-time professional service expenses related to 2023 strategic initiatives and business development activities as well as reduced legal and patent costs.
