THE WOODLANDS, Texas, Nov. 08, 2022 (GLOBE NEWSWIRE) -- Lexicon Pharmaceuticals, Inc. (Nasdaq: LXRX) today announced that the final results from the Phase 2 RELIEF-DPN-1 trial of its investigational drug LX9211, a novel, highly selective inhibitor of adaptor-associated kinase 1 (AAK1), will be presented during a podium presentation at the 16^th Annual Pain Therapeutics Summit in Washington, D.C.

The presentation will be given by Anand Patel, M.D., the Chief Medical Officer at Conquest Research and a principal investigator in the RELIEF-DPN-1 study, on November 14^th at 3:35pm ET, and is entitled:

• “A Phase 2 Study to Evaluate the Efficacy, Safety, and Pharmacokinetics of LX9211 in the Treatment of Diabetic Peripheral Neuropathic Pain (RELIEF-DPN-1).”

The presentation will describe the preclinical basis for the program, the framework of the trial, and an analysis of the final results from this successful proof-of-concept study.

Following the presentation, Dr. Patel will join Lexicon management on a live conference call and webcast at 5:00pm ET to discuss the study results. The dial-in number for the conference call is 888-886-7786 and the conference ID for all callers is 28989106.

About the RELIEF-DPN-1 Study

RELIEF-DPN-1 was a Phase 2 randomized, double-blind, placebo-controlled, parallel-group, multicenter study evaluating the efficacy, safety and pharmacokinetics of LX9211 in the treatment of painful diabetic neuropathy, also referred to as diabetic peripheral neuropathic pain. The study enrolled 319 patients at 45 U.S. clinical sites, evaluating three treatment groups receiving placebo or one of two dosing regimens of LX9211 (an initial single dose of 100 mg followed by once-daily doses of 10 mg or an initial single dose of 200 mg followed by once-daily doses of 20 mg). The primary efficacy endpoint under evaluation was the change from baseline to week 6 in ADPS, based on the 11-point numerical rating scale. The results of the study on the primary endpoint showed a reduction from baseline in ADPS of 1.39 points (p=0.007 versus placebo) in the low dose arm and 1.27 points (p=0.030 versus placebo) in the high dose arm, compared to 0.72 in the placebo arm. Under the statistical analysis plan for the study, a p-value of less than 0.028 was considered statistically significant.

The RELIEF-DPN-1 study was the first of two Phase 2 proof-of-concept studies evaluating LX9211 in neuropathic pain. LX9211 is also under evaluation in RELIEF-PHN-1, a study in patients with post-herpetic neuralgia, from which Lexicon is targeting top-line results around the end of the fourth quarter of 2022.

About LX9211

Discovered using Lexicon’s unique approach to gene science, LX9211 is a potent, orally delivered, selective small molecule inhibitor of adaptor-associated kinase 1 (AAK1). Lexicon identified AAK1 in its target discovery efforts as a promising approach for the treatment of neuropathic pain and identified LX9211 and another development candidate in a neuroscience drug discovery alliance with Bristol-Myers Squibb from which Lexicon holds exclusive development and commercialization rights. Preclinical studies of LX9211 demonstrated central nervous system penetration and reduction in pain behavior in models of neuropathic pain without affecting opiate pathways. LX9211 has received Fast Track designation from the U.S. Food and Drug Administration for the development in diabetic peripheral neuropathic pain.
