• Presented initial preclinical data from ETX-123, Eliem's lead Kv7 program candidate, demonstrating a promising profile and confirming the proposed mechanism of action on neuronal excitability
  
• Additional preclinical data updates for ETX-123 expected in 2023

SEATTLE and CAMBRIDGE, United Kingdom, May 11, 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 ended March 31, 2023.

“We were excited to share our initial preclinical data from ETX-123, our lead candidate in the Kv7 program, during the first quarter,” said Andrew Levin, M.D., Ph.D., executive chairman of Eliem Therapeutics. “The initial data demonstrate high potency and differentiated selectivity. The data also confirm the proposed mechanism of action on neuronal excitability, which we believe, has the potential to improve the lives of patients suffering from a variety of CNS disorders. With a strong balance sheet funding operations into 2027, we expect to have the financial strength to fund multiple catalysts and advance this exciting program into the clinic.”

Recent Highlights

• Presented initial ETX-123 preclinical data at the 7th RSC-BMCS / SCI Symposium on Ion Channels as Therapeutic Targets in March 2023. The data presented confirmed ETX-123’s mechanism of action on neuronal excitability via modulation of Kv7 and demonstrated its high potency and differentiated selectivity for Kv7.2/3 in electrophysiology assays. Further screens also confirmed an encouraging broad selectivity profile, including no GABA_A, hERG or other off-target activities at anticonvulsant doses. Additionally, in vivo oral administration of ETX-123 dose-dependently inhibited seizures in the rat maximal electroshock seizures (MES) model, with an encouraging separation versus doses that impaired performance in the rotarod, a CNS side-effect profiling model.
• Additional preclinical data on ETX-123 will be presented at two upcoming scientific and medical conferences. The Company will present additional data at the Epilepsy Therapies & Diagnostics Development XVII Conference being held May 31-June 2, 2023 in Aventura, FL and at the 2nd International Kv7 Channels Symposium 2023 being held September 13-15, 2023 in Naples, Italy.

Program Updates and Anticipated Key Milestones

• The Company has initiated synthesis scale-up for its lead Kv7 candidate, ETX-123, to enable the initiation of investigational new drug (IND)-enabling safety studies, with Phase 1 clinical studies currently 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 MES rat model.
• A comprehensive update can be found in the Company’s corporate presentation linked here.

First Quarter 2023 Financial Results

• Cash Position: Cash, cash equivalents and marketable securities was $109.4 million as of March 31, 2023, as compared to $123.6 million as of December 31, 2022. The Company’s current cash, cash equivalents and marketable securities are expected to fund operations into 2027.
• Research and Development (R&D) expenses: R&D expenses were $5.7 million for the three months ended March 31, 2023, compared to $8.3 million for the same period in 2022.
• General and Administrative (G&A) expenses: G&A expenses were $17.7 million for the three months ended March 31, 2023, compared to $4.9 million for the same period in 2022.
• Net loss: Net loss was $22.3 million for the three months ended March 31, 2023, compared to $13.2 million for the same period in 2022.
• Net loss for the quarter included $15.8 million of one-time costs for termination benefits associated with the recently announced corporate restructuring, of which $9.0 million related to stock-based compensation. Of these costs, $1.8 million was included in R&D expenses and $14.0 million in G&A expenses.
