Axsome Therapeutics Announces AXS-12 Achieves Primary Endpoint in ENCORE Long-Term Phase 3 Trial in Narcolepsy

NEW YORK, Nov. 26, 2024 (GLOBE NEWSWIRE) — Axsome Therapeutics, Inc. (NASDAQ: AXSM), a biopharmaceutical company developing and delivering innovative therapies for the management of central nervous system (CNS) disorders, today announced that AXS-12 (reboxetine), a highly selective and potent norepinephrine reuptake inhibitor and cortical dopamine modulator, achieved the primary endpoint in the ENCORE Phase 3 trial, demonstrating a statistically significant improvement in the frequency of cataplexy attacks compared to placebo. AXS-12 was also well tolerated with long-term dosing with a safety profile consistent with that observed in previously completed trials. ENCORE was a multi-center, two-period Phase 3 trial evaluating the long-term efficacy and safety of AXS-12 in patients with narcolepsy with cataplexy, consisting of a 6-month open-label AXS-12 treatment period, followed by a 3-week double-blind, placebo-controlled, randomized withdrawal period. The trial enrolled 68 patients in the 6-month AXS-12 treatment period. Patients (n=42) were then randomized in a 1:1 ratio to continue treatment with AXS-12 or to discontinue AXS-12 and switch to placebo for 3 weeks.
