We are 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. These disorders often occur when neurons are overly excited or inhibited, leading to an imbalance, and our focus is on restoring homeostasis. We are developing a pipeline of clinically differentiated product candidates focused on validated mechanisms of action with broad therapeutic potential to deliver improved therapeutics for patients with these disorders. Our two lead clinical-stage candidates are ETX-810 and ETX-155. ETX-810 is a novel palmitoylethanolamide (PEA) prodrug initially being developed for the treatment of diabetic peripheral neuropathic pain (DPNP) and pain associated with lumbosacral radiculopathy (LSR, commonly referred to as sciatica). ETX-810 is being evaluated in two Phase 2a clinical trials that are expected to report topline data in the first half of 2022. ETX-155 is a neurosteroid GABAA receptor positive allosteric modulator (PAM) initially being developed for the treatment of major depressive disorder (MDD), perimenopausal depression (PMD) and focal onset seizures (FOS), the most common type of seizure in people with epilepsy. We plan to initiate two Phase 2a clinical trials for ETX-155 in patients with MDD and PMD which are expected to report topline data in the first half of 2023, and a Phase 1b clinical trial in patients with photosensitive epilepsy that is expected to report topline data by the first half of 2022.
