November 08 2022 - 8:58AM
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 16th 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 14th
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. The live webcast and replay may be accessed by
visiting Lexicon’s website at www.lexpharma.com/events. An archived
version of the webcast will be available on the website for 14
days.
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.
