Eliem Therapeutics Reports Third Quarter Financial and Business Highlights
Advanced ETX-155 clinical development program, with the first subject successfully screened in epilepsy proof-of-concept trial and significant progress made toward the initiation of major depressive disorder (MDD) and perimenopausal depression (PMD) clinical trials
Continued to enroll ETX-810’s two Phase 2a chronic pain clinical trials, with topline data anticipated in the first half of 2022
On track to progress Kv7.2/3 channel opener program into Investigational New Drug (IND)-enabling studies in the first half of 2022
SEATTLE and CAMBRIDGE, United Kingdom, Nov. 08, 2021 (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 ended September 30, 2021.
“Our clinical execution is progressing well,” said Bob Azelby, Eliem’s president and chief executive officer. “For ETX-155, we are excited to report that we have completed our Phase 1 studies, we have successfully screened our first patient in our photosensitive epilepsy (PSE) proof-of-concept clinical trial and we continue to progress clinical development activities for the launch of our phase 2a trials evaluating ETX-155 in patients with MDD and PMD. As we look to expand our clinical pipeline, we are increasingly excited about the potential of our Kv7.2/3 channel opener program as a clinically validated mechanistic approach to treat diseases such as epilepsy, pain and MDD, and we remain on track to progress the program into IND-enabling studies in the first half of 2022.”
Third Quarter 2021 Highlights and Recent Developments
Completed 14-day repeat dose Phase 1 study demonstrating ETX-155 was well tolerated with an approximate 40-hour half-life supporting once-daily dosing. The 14-day, repeat dose, Phase 1 study evaluated the pharmacokinetic profile and safety of ETX-155 in 20 healthy human subjects, evaluating 60 mg ETX-155 (n=15) or placebo (n=5) dosed daily in the evening for 14 days. Results demonstrated ETX-155 reached steady state concentration at Day 8 and had an approximate 40-hour half-life, confirming ETX-155’s desirable profile for a once-daily dosing regimen. The study also confirmed that ETX-155 was generally well tolerated with no severe or serious adverse events, or discontinuations. All treatment-emergent adverse events (TEAEs), including central nervous system (CNS) adverse events, were mild/moderate and transient. In particular, all somnolence adverse events were mild and the incidence was comparable in the ETX-155 and placebo groups. Notably, somnolence events were sporadic, and no subject who reported somnolence in either the ETX-155 or placebo arms reported it more than once during the dosing or follow-up period. In addition, there was no clinically meaningful difference compared to placebo in sleep quality or next morning state of arousal, as measured by the Leeds Sleep Evaluation Questionnaire. The tolerability and safety findings of this study were consistent with those of the previous 7-day repeat dose and single ascending dose Phase 1 study. Collectively, the Company’s Phase 1 studies have demonstrated that ETX-155 has differentiated pharmacokinetic properties, including no clinically meaningful food effect and an approximate 40-hour half-life to enable a once-daily dosing regimen.
Screened the first subject in ETX-155 photosensitive epilepsy clinical trial: The Company anticipates dosing the first subject in the single-arm proof-of-concept Phase 1b PSE trial by the end of 2021. Precedent literature demonstrates that activity in single-dose PSE trials can be a reliable predictor of anticonvulsant activity in various forms of epilepsy, such as focal onset seizure.
Advanced study start-up activities for ETX-155 Phase 2a clinical trials in MDD and PMD: The Company anticipates dosing the first subject in each of these studies in early 2022, assuming regulatory approval of its IND application.
Program Updates and Anticipated Milestones
ETX-810 in chronic pain: ETX-810 is a novel new chemical entity prodrug of the bioactive lipid palmitoylethanolamide that is currently being evaluated in two Phase 2a clinical trials in subjects with diabetic peripheral neuropathic pain (DPNP) and lumbosacral radicular pain (LSRP), commonly referred to as sciatica.
- ETX-810 in DPNP. The ongoing 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 DPNP remains on track to have topline data readout during the first half of 2022.
- ETX-810 in LSRP. The ongoing 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 remains on track to have topline data readout during the first half of 2022.
ETX-155 in depression and epilepsy: ETX-155 is a novel GABAA receptor positive allosteric modulator (PAM) that Eliem plans to evaluate in subjects with MDD, PMD and focal onset seizure (FOS).
- ETX-155 in FOS. The Company expects to report topline data from its ongoing single-arm, proof-of-concept Phase 1b trial in subjects with PSE in the first half of 2022. This study is intended to support progression into a Phase 2 study in FOS, given precedent literature demonstrating that activity in single dose PSE trials can be a reliable predictor of anticonvulsant activity in focal onset seizure.
- ETX-155 in MDD and PMD. Assuming regulatory approval of the Company’s IND application, the Company expects to dose its first subjects in two randomized, placebo-controlled, Phase 2a proof-of-concept trials of ETX-155 in early 2022. Topline data from each trial is expected in the first half of 2023.
Kv7.2/3 channel opener program: The Company’s preclinical program targets the Kv7.2/3 potassium channel that has been shown to control neuronal excitability, with clinical validation in pain and epilepsy. The program remains on track to progress to IND-enabling studies in the first half of 2022.
Anxiolytic for generalized anxiety disorder (GAD): The Company is also in early preclinical development of a novel, rapid-acting, non-sedating, non-addictive anxiolytic for the potential treatment of GAD, based on a clinically validated mechanism. The Company plans to continue the preclinical development of this program in 2022.
