Lexicon Announces Completion of Screening in Phase 2B Progress Study of LX9211 in Diabetic Peripheral Neuropathic Pain (DPNP)

Top-line Data Now Anticipated in Q1 2025 

LX9211 has previously received Fast Track designation from the U.S. Food and Drug Administration (FDA) for DPNP 

THE WOODLANDS, Texas, Oct. 22, 2024 (GLOBE NEWSWIRE) — Lexicon Pharmaceuticals, Inc. (Nasdaq: LXRX) today announced that it has closed screening and expects to complete enrollment ahead of schedule in PROGRESS (A Phase 2b, Dose-ranging, Randomized, Double-blind, PlacebO-controlled, Parallel-GRoup, MulticEnter Study in PatientS with Diabetic Peripheral Neuropathic Pain) studying LX9211, an orally-delivered, potent, selective, investigational small molecule inhibitor of adaptor-associated kinase 1 (AAK1). The Company also updated its expectations for the timing of anticipated top-line data, from the second quarter of 2025 to the first quarter of 2025.

“We are excited to be ahead of schedule for a near-term completion of PROGRESS for LX9211, with top-line data now anticipated in Q1 of next year,” said Craig Granowitz, M.D., Ph.D., Lexicon’s senior vice president and chief medical officer. “There have been no new, non-opioid medications approved for neuropathic pain in more than two decades, and there is an urgent need for novel treatment options. We believe that LX9211 has the potential to positively impact the lives of people suffering with neuropathic pain and we thank the investigators, study sites, Lexicon clinical team members and especially the patients for their participation in this important study.” 

PROGRESS commenced in December of 2023 with the goal of enrolling adult patients with a diagnosis of diabetes (type 1 or type 2) with moderate to severe DPNP, with patients allowed to continue their current pain therapy. The primary endpoint of PROGRESS is a reduction of Average Daily Pain Score (ADPS) at 8 weeks.
