 Completed dosing in Phase 2a clinical trial of ETX-810 in subjects with diabetic peripheral neuropathic pain; topline data to be presented in 1H 2022 Interim data from Phase 1b clinical trial of ETX-155 in subjects with photosensitive epilepsy to be presented in 1H 2022 Submitted Investigational New Drug (IND) application for ETX-155 to the U.S. Food and Drug Administration (FDA)’s psychiatry division SEATTLE and CAMBRIDGE, United Kingdom, March 07, 2022 (GLOBE NEWSWIRE) — Eliem Therapeutics, Inc. (Nasdaq: ELYM), a clinical-stage biotechnology company focused on developing novel therapies for neuronal excitability disorders to address unmet needs in chronic pain, psychiatry, epilepsy and other disorders of the peripheral and central nervous systems, today reported financial results and business highlights for the quarter and year ended December 31, 2021. “In 2021, we made significant progress on our pipeline and raised sufficient capital to fund the company through multiple catalysts,” said Bob Azelby, president and chief executive officer of Eliem Therapeutics. “We were excited to start off the new year by completing our Phase 2a clinical trial of ETX-810 in diabetic peripheral neuropathic pain and look forward to presenting the topline data from this trial in the first half of this year. Even with a polypharmacy approach, a majority of patients with chronic pain are unable to achieve clinically significant reductions in pain and are often balancing tolerability tradeoffs to achieve additional pain reduction. With ETX-810, we believe we have the potential to introduce a differentiated chronic pain therapy that is both efficacious and well-tolerated. On our ETX-155 program, we expect to report interim data on our proof-of-concept Phase 1b study for photosensitive epilepsy, and we look forward to dosing patients in our depression studies assuming FDA clearance of our IND.” Recent Highlights Completed dosing in our Phase 2a clinical trial evaluating ETX-810 in subjects with diabetic peripheral neuropathic pain (DPNP). The Company has completed dosing for its Phase 2a clinical trial evaluating the efficacy and safety of ETX-810 in subjects with DPNP. The Company remains on track to announce topline data from this trial in the first half of 2022.Submitted IND application for ETX-155 to the psychiatry division of the FDA. The Company submitted an IND application with the U.S. Food and Drug Administration (FDA) in the first quarter of 2022, and assuming FDA clearance to proceed, the Company expects to dose the first subjects in two randomized, placebo-controlled, Phase 2a proof-of-concept depression trials of ETX-155 in the first half of 2022.Hosted a virtual investor event featuring opinion leaders in chronic pain research. In February 2022, the Company held a virtual investor event that provided an in-depth review on the unmet needs in chronic pain treatment, the existing data supporting the mechanism of ETX-810, and ETX-810’s clinical program and its potential commercial opportunity. A replay of the event can be found here. Program Updates and Anticipated Key Milestones ETX-810 in chronic pain: ETX-810 is a novel, new chemical entity prodrug of the bioactive lipid palmitoylethanolamide (PEA) that is currently being evaluated in two Phase 2a clinical trials in subjects with DPNP and lumbosacral radicular pain (LSRP), commonly referred to as sciatica. ETX-810 in DPNP. The Company expects to announce topline data in the first half of 2022 from its Phase 2a, multi-center, randomized, double-blind, placebo-controlled, parallel-group clinical trial evaluating the efficacy and safety of ETX-810 in subjects with DPNP. The Company plans to present results for the primary efficacy endpoint, which is the change from baseline to week 4 in the weekly average of the daily pain score measured with the Pain Intensity Numerical Rating Scale (PI-NRS), including p-value, as well as information on safety and tolerability.ETX-810 in LSRP. Enrollment remains ongoing for the Phase 2a prospective, multi-center, randomized, double-blind, placebo-controlled, parallel-group clinical trial evaluating the efficacy and safety of ETX-810 in subjects with LSRP. The Company continues to expect to complete enrollment in the first half of 2022 with topline data in the second half of 2022. ETX-155 in depression and epilepsy: ETX-155 is a novel GABAA receptor positive allosteric modulator that the Company plans to evaluate in subjects with major depressive disorder (MDD), perimenopausal depression (PMD), and epilepsy.

The Company submitted an Investigational New Drug (IND) application with the U.S. Food and Drug Administration’s (FDA) psychiatry division in the first quarter of 2022, including plans for characterizing and qualifying metabolites identified in its 14-day Phase 1 trial. Assuming FDA clearance to proceed, the Company expects to dose the first subjects in two randomized, placebo-controlled, Phase 2a proof-of-concept trials of ETX-155 in the first half of 2022 and expects topline data in the second half of 2023.ETX-155 in epilepsy. The Company plans to announce interim data in the first half of 2022 from its double-blind cross-over Phase 1b trial in subjects with photosensitive epilepsy (PSE), a single dose proof-of-concept study for epilepsy.
