Shares of Eliem Therapeutics Inc. fell 56% on the company’s announcement that it would end development of its non-opioid palmitoylethanolamide prodrug, ETX-810, in diabetic peripheral neuropathic pain following a phase IIa failure. It was part of a double dose of bad news reported by Seattle-based Eliem, which also is delaying phase II development of depression candidate ETX-155 to resolve issues of lower-than-expected drug exposure in a phase I study of the neuroactive steroid GABAA receptor positive allosteric modulator in photosensitive epilepsy.
