Progressing IND-enabling studies for ETX-123 and further preclinical development of Kv7.2/3 channel opener program

Implemented corporate reorganization and pipeline reprioritization extending cash runway into 2027

SEATTLE and CAMBRIDGE, United Kingdom, March 06, 2023 (GLOBE NEWSWIRE) -- Eliem Therapeutics, Inc. (NASDAQ:ELYM), a biotechnology company focused on developing novel therapies for neuronal excitability disorders to address unmet needs in psychiatry, epilepsy, chronic pain, and other disorders of the peripheral and central nervous systems, today provided a business update and reported financial results for the quarter and year ended December 31, 2022.

"We are excited to advance our Kv7 program forward with ETX-123 as the lead candidate," said Andrew Levin, M.D., Ph.D., Executive Chairman of Eliem Therapeutics. "Our Kv7 program utilizes a proven mechanism of action which we believe has the potential to improve the lives of patients suffering from a variety of CNS disorders. We look forward to presenting preclinical data at the 7th RSC-BMCS / SCI Symposium on Ion Channels as Therapeutic Targets being held later this month. With a strong balance sheet funding operations into 2027, we are in an optimal position to execute on ETX-123 and the Kv7 program."

Recent Highlights

Announced Corporate Reorganization and Pipeline Reprioritization to Focus on Advancing High Potential Kv7 Program: In February, the Company's Board of Directors determined that it is in the best interests of the Company and its stockholders to reprioritize Eliem's pipeline to focus on its high potential preclinical Kv7.2/3 program ("Kv7 Program") and the development of its lead Kv7.2/3 candidate, ETX-123. The Company paused all further development of ETX-155, a novel GABA_Areceptor positive allosteric modulator neuroactive steroid ("GABA_A PAM") that is Phase 2-ready for major depressive disorder (MDD), with the potential to also pursue development in epilepsy. As part of this reprioritization, the Company is retaining its core R&D team under the continued leadership of Dr. Valerie Morisset, EVP R&D and Chief Scientific Officer, to carry on driving forward the Kv7 Program and exploring other pipeline opportunities, and will reduce its workforce by approximately 55% in the first half of 2023.
Appointed Andrew Levin as Executive Chairman: Following the corporate reorganization and departure of Bob Azelby, Eliem's former President and Chief Executive Officer, Andrew Levin, current Chairman of the Board, was appointed as Executive Chairman overseeing the day-to-day operations of the Company.
Cash Runway Extended into 2027: As a result of the corporate reorganization and pipeline reprioritization, the Company's current cash, cash equivalents and marketable securities is expected to fund operations into 2027.

Program Updates and Anticipated Key Milestones

The Company has initiated the scaling up synthesis of the lead Kv7 candidate, ETX-123, to enable the initiation of investigational new drug (IND)-enabling safety studies, with Phase 1 studies planned to initiate in the first half of 2024.
The Company's novel Kv7 compounds, including additional pre-candidates, have demonstrated high potency and differentiated selectivity in electrophysiology assays, and in vivo anticonvulsant activity in the maximal electroshock seizure (MES) rat model.
Initial ETX-123 preclinical data will be presented at the 7th RSC-BMCS / SCI Symposium on Ion Channels as Therapeutic Targets being held March 27-28, 2023 at the Wellcome Genome Campus in Cambridge, UK.
