Company to focus on Kv7.2/3 channel opener program and development of lead candidate, ETX-123

Pausing clinical development of ETX-155 for Major Depressive Disorder (MDD) due to challenging capital environment

Implementing corporate reorganization to extend cash runway into 2027

SEATTLE and CAMBRIDGE, United Kingdom, Feb. 09, 2023 (GLOBE NEWSWIRE) -- Eliem Therapeutics, Inc. (Nasdaq: ELYM) (“Eliem” or the “Company”), 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 strategic business update and announced a leadership transition.

Pipeline Reprioritization

The Company’s Board of Directors has determined that it is in the best interests of the Company and its stockholders to re-prioritize 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. Kv7.2/3 is a target that has clinical validation in epilepsy and pain, with further potential in depression disorders. Eliem has identified multiple Kv7.2/3 modulators in a novel and highly differentiated chemical space, and its lead candidate, ETX-123, has demonstrated excellent potency, selectivity, and in vivo anticonvulsant activity. The Company plans to commence a first-in-human Phase 1 trial in the first half of 2024.

In connection with its focus on the Kv7 Program, the Company will pause all further development of ETX-155, a novel GABA_A receptor 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. The Company has completed Phase 1 clinical trials, which demonstrated an encouraging pharmacokinetic, safety and tolerability profile for the 60-milligram dose of ETX-155. A Phase 2a clinical trial in subjects with MDD was ready to initiate in the current quarter.   However, the Board determined that, given current capital market conditions and investor sentiment around the GABA_A PAM opportunity in MDD, it is not in the best interests of the Company or its stockholders to invest in the Phase 2a MDD trial at this time. Eliem would like to thank employees, investigators and vendors who were operationalizing the Phase 2a clinical trial.  

Corporate Reorganization and Leadership Transition

As a result of the decision to pause the development of ETX-155 and focus on the Kv7 Program, the Board has approved a corporate reorganization plan to conserve financial resources. As part of the reorganization, the Company will reduce its workforce by approximately 55% in the first half of 2023.

The Company will continue its focus on treatments for neuronal excitability disorders, and is retaining its core R&D team, led by Dr. Valerie Morisset, EVP R&D and Chief Scientific Officer. This team will carry on driving ETX-123 development forward and executing on other pipeline opportunities, including other opportunities for the Kv7 Program.  

Eliem has also announced today that, in connection with this reorganization, Bob Azelby, president and chief executive officer, and a member of the Eliem Board, will be departing the Company and the Board imminently, and Andrew Levin, current Chairman of the Board, has been appointed as Executive Chairman overseeing the day-to-day operations of the Company, effective upon Mr. Azelby’s departure.

In addition, Erin Lavelle, executive vice president, chief operating officer and chief financial officer, and Jim Bucher, executive vice president and general counsel, will depart the Company following a short transition period.

“We are excited about this next chapter for Eliem with our encouraging Kv7 Program, utilizing 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 believe the Company is well positioned to execute on ETX-123 and the overall Kv7 Program, and our current balance sheet provides us significant runway to see the program through compelling data catalysts,” said Dr. Levin. “On behalf of the full Board, I extend my deepest gratitude to Bob, Erin, and Jim for their leadership and contributions to Eliem, and to our departing employees for all their efforts on behalf of the Company.”

The Company preliminarily estimates that its cash, cash equivalents and marketable securities were $123.6 million as of December 31, 2022. This preliminary estimate is not a comprehensive statement of the Company’s financial results for the year ended December 31, 2022 and has not been audited, reviewed, or compiled by its independent registered public accounting firm. The Company’s current cash, cash equivalents and marketable securities are expected to fund operations into 2027, with further guidance to be provided as clinical data is available for the Kv7 Program.

Overview of Eliem’s Kv7.2/3 Channel Opener Program 

The Company’s preclinical program targets the Kv7.2/3 potassium channel (Kv7), a target that has clinical validation in pain and epilepsy.

• The Company has initiated the scaling up synthesis of its lead candidate ETX-123, to enable the initiation of 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.
• The Company has filed foundational intellectual property claims on its novel Kv7 compounds.
