Lexicon Pharmaceuticals Announces Successful End-of-Phase 2 Meeting with FDA For Pilavapadin in the Treatment of Diabetic Peripheral Neuropathic Pain
– No objections raised by FDA to advancement of pilavapadin into Phase 3 development utilizing two-arm registrational studies of 10 mg daily dose compared to placebo –
THE WOODLANDS, Texas, Jan. 21, 2026 (GLOBE NEWSWIRE) — Lexicon Pharmaceuticals, Inc. (Nasdaq: LXRX) today announced the successful completion of the End-of-Phase 2 (EOP2) Meeting with the U.S. Food and Drug Administration (FDA) for pilavapadin in diabetic peripheral neuropathic pain (DPNP). During the meeting, the FDA raised no objections to the advancement of pilavapadin into Phase 3 development, which would include two placebo-controlled, 12-week, two arm registrational studies comparing the 10 mg daily dose to placebo. The primary endpoint of the Phase 3 studies will be the change in average daily pain score (ADPS) from baseline to Week 12.
“Our End-of-Phase 2 meeting with FDA was productive and provided Lexicon with the insights needed to design a robust Phase 3 program, with the goal of making the first non-opioid DPNP medicine available to patients in over two decades,” said Mike Exton, Ph.D., chief executive officer and director of Lexicon. “Furthermore, the FDA did not require any unanticipated preclinical or clinical studies that would be expected to complicate or delay the advancement of this program into Phase 3 development and a potential regulatory submission.”
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.
