CAMBRIDGE, Mass., Nov. 04, 2024 (GLOBE NEWSWIRE) -- Editas Medicine, Inc. (NASDAQ:EDIT), a clinical-stage gene editing company, today reported financial results for the third quarter 2024 and provided business updates.

"Achieving preclinical proof of concept of HBG1/2 editing in HSPCs using our proprietary targeted LNP, puts us on a clear path to develop a potentially first- and best-in-class in vivo gene edited medicine for the treatment of sickle cell disease and beta thalassemia," commented Gilmore O'Neill, M.B., M.M.Sc., President and Chief Executive Officer, Editas Medicine. "As we continue our process to partner or out-license reni-cel, we also look forward to sharing a substantial clinical update from the RUBY trial of reni-cel, a potentially best-in-class cell therapy for the treatment of sickle cell disease, at ASH in December."

"I am proud of the Editas team's work and our advancement in 2024 as we move closer to achieving our vision of becoming a leader in in vivo programmable gene editing medicine," added Dr. O'Neill.

Recent Achievements and Outlook

Ex Vivo Hemoglobinopathies

Reni-cel (renizgamglogene autogedtemcel, previously EDIT-301) Partnering/Out-licensing
- The Company has engaged Moelis & Company LLC, a leading global independent investment bank, to lead the global process to partner or out-license reni-cel.

Reni-cel for Severe Sickle Cell Disease (SCD)
- The Company will present a substantive RUBY clinical trial update of 28 patients with considerable clinical follow-up at the American Society of Hematology (ASH) Annual Meeting and Exposition, December 7-10, 2024.
  - Dataset will include safety data and efficacy data, including hematology parameters, vaso-occlusive events (VOEs), and patient reported outcomes (PROs).
- The Company continues to dose adult patients in the RUBY trial and has dosed 28 patients to date.
- The Company continues to manufacture drug product for the initial adolescent cohort patients and schedule dosing.
- As previously announced, the Company has completed enrollment of the adult and adolescent cohorts of the Phase 1/2/3 RUBY trial for SCD.

Reni-cel for Transfusion-dependent Beta Thalassemia (TDT)
- The Company is on-track to present additional clinical data from the EdiTHAL trial by year-end 2024.
- As previously announced, the Company completed enrollment of the adult cohort of the EdiTHAL trial for TDT and continues to dose patients.

In Vivo Medicines

In vivo Preclinical Proof of Concept Achieved: Hematopoietic Stem and Progenitor Cell (HSPC) Editing
- As disclosed on October 22, the Company established in vivo preclinical proof of concept for the development of an in vivo medicine for sickle cell disease and beta thalassemia by demonstrating in vivo hematopoietic stem and progenitor cell (HSPC) editing of HBG1/2 promoter utilizing a novel, Editas-proprietary targeted lipid nanoparticle (tLNP) for extrahepatic tissue delivery in a humanized mouse model (mice engrafted with human hematopoietic stem cells).
- The Company will provide an update on its in vivo progress and pipeline development in 1Q 2025.
- The Company continues to pursue an in vivo strategy and approach aimed at driving functional upregulation of gene expression to address loss of function or deleterious mutations.

Additional in vivo Targets
- Editas Medicine and Genevant Sciences entered into a collaboration and nonexclusive license agreement to combine Editas' CRISPR Cas12a genome editing systems with Genevant's proprietary LNP technology in the development of in vivo gene editing medicines directed to functional upregulation of two liver targets.

Business Development

On October 3, 2024, Editas Medicine announced the sale of certain future license fees and other payments owed to the Company under its Cas9 license agreement with Vertex Pharmaceuticals to a wholly owned subsidiary of DRI Healthcare Trust (DRI) for an upfront cash payment of $57 million. The upfront cash payment brings non-dilutive capital to Editas Medicine, helping enable further pipeline development and related strategic priorities.
The Company ended the third quarter 2024 with approximately $265.1 million of cash, cash equivalents, and marketable securities, or approximately $322.1 million following receipt of the upfront cash payment from DRI.

Third Quarter 2024 Financial Results

Cash, cash equivalents, and marketable securities as of September 30, 2024, were $265.1 million compared to $318.3 million as of June 30, 2024. The Company expects the existing cash, cash equivalents, and marketable securities, together with the upfront cash payment from DRI and the retained portions of the payments payable under the license agreement with Vertex, to fund operating expenses and capital expenditures into the second quarter of 2026.

Third Quarter 2024

For the three months ended September 30, 2024, net loss attributable to common stockholders was $62.1 million, or $0.75 per share, compared to net loss of $45.0 million, or $0.55 per share, for the same period in 2023.
Collaboration and other research and development revenues decreased to $0.1 million for the three months ended September 30, 2024, compared to $5.3 million for the same period in 2023. The decrease is primarily attributable to the receipt in the 2023 period of the upfront payment for the non-exclusive license to Vor Bio.
Research and development expenses increased by $7.1 million to $47.6 million for the three months ended September 30, 2024, compared to $40.5 million for the same period in 2023. The increase is primarily related to clinical and manufacturing costs related to the accelerated progression of the Company's reni-cel program as well as costs attributable to in vivo research and discovery.
General and administrative expenses increased by $3.1 million to $18.1 million for the three months ended September 30, 2024, compared to $15.0 million for the same period in 2023. The increase is primarily attributable to increased employee-related expenses related to increased headcount to support business operations due to the progression of reni-cel program.
