THE WOODLANDS, Texas, Sept. 04, 2025 (GLOBE NEWSWIRE) -- Lexicon Pharmaceuticals, Inc. (Nasdaq: LXRX) today announced that the Company will present new data demonstrating the reduction of neuropathic pain by pilavapadin in preclinical models of chemotherapy-induced peripheral neuropathy (CIPN) and multiple sclerosis (MS) at the 9^th International Congress on Neuropathic Pain - (NeuPSIG) 2025. The findings highlight the relevance of inhibiting pilavapadin’s novel target, AAK1, for the modulation of pain signaling. The conference is being held September 4 – 6, 2025 in Berlin, Germany.

Presentation details:

Poster: LX9211, a Novel AAK1 Inhibitor, Alleviates Pain in Preclinical Models of Chemotherapy-induced Neuropathic Pain and Multiple Sclerosis
Date: Saturday, September 6, 2025
Time: 8:30 a.m. – 6:00 p.m. CEST
Location: Exhibition Poster Area
Presenter: Suma Gopinathan, Senior Vice President, Discovery, Lexicon Pharmaceuticals

“We are encouraged by the promising results with pilavapadin in preclinical models of CIPN and MS, which highlight the potential of pilavapadin in additional neuropathic pain indications beyond diabetic peripheral neuropathic pain (DPNP),” said Suma Gopinathan, Senior Vice President of Discovery for Lexicon. “These data build upon the robust body of evidence supporting AAK1 inhibition as a powerful target for diverse neuropathic pain conditions.”

Separately, Lexicon will also present a poster entitled “Study Design and Rationale of PROGRESS: Pilavapadin in a Phase 2b, Dose-ranging, Double-blind, Placebo-controlled Study in Diabetic Peripheral Neuropathic Pain.”

About Pilavapadin
Discovered using Lexicon’s unique approach to gene science, pilavapadin is a potent, once-daily, orally delivered, selective, investigational small molecule inhibitor of AAK1, a novel target for neuropathic pain which inhibits reuptake and recycling of neurotransmitters involved in pain signaling without affecting opiate pathways. Lexicon identified AAK1 in its target discovery efforts as a promising approach for the treatment of neuropathic pain. Preclinical studies of pilavapadin demonstrated central nervous system penetration and reduction in pain behavior in models of neuropathic pain without affecting opiate pathways.

Pilavapadin has received Fast Track designation from the U.S. Food and Drug Administration for development in diabetic peripheral neuropathic pain (DPNP).
