Migraine: In February 2025 , Axsome announced positive topline results from the EMERGE Phase 3 open-label trial of SYMBRAVO in patients experiencing inadequate response to oral CGRP inhibitors. The study achieved its primary endpoint by demonstrating statistically significantly greater migraine treatment response with SYMBRAVO compared to prior oral CGRP inhibitors, as assessed by the Migraine Treatment Optimization Questionnaire (mTOQ-4). In the trial, SYMBRAVO rapidly and substantially improved migraine pain and most bothersome symptoms. AXS-12 AXS-12 (reboxetine) is Axsome’s novel, oral, investigational, highly selective and potent norepinephrine reuptake inhibitor and cortical dopamine modulator being developed for the treatment of narcolepsy. AXS-12 has been granted FDA Orphan Drug designation for narcolepsy. Narcolepsy: Axsome previously announced the completion of its clinical program of AXS-12 in patients with narcolepsy with cataplexy consisting of three controlled Phase 2 and Phase 3 efficacy trials and a long-term safety trial. AXS-12 achieved the primary endpoints and rapidly and substantially reduced cataplexy attacks, improved excessive daytime sleepiness, and improved cognitive function compared to placebo in all three efficacy trials (CONCERT, SYMPHONY, and ENCORE). The Company anticipates submitting an NDA to the FDA in the second half of 2025. AXS-14 AXS-14 (esreboxetine) is Axsome’s novel, oral, investigational, highly selective and potent norepinephrine reuptake inhibitor being developed for the management of fibromyalgia. Esreboxetine, the SS-enantiomer of reboxetine, is more potent and selective than racemic reboxetine. Fibromyalgia: Axsome has submitted an NDA to the FDA for AXS-14 for the management of fibromyalgia. The Company anticipates the FDA’s decision on acceptance of the filing in the second quarter of 2025. Scientific Presentations In April 2025 , Axsome presented the positive topline results from the ACCORD-2 Phase 3 trial of AXS-05 in Alzheimer’s disease agitation and the SYMPHONY Phase 3 trial of AXS-12 in narcolepsy at the 2025 American Academy of Neurology (AAN) Annual Meeting. Additional presentations included findings from a new network meta-analysis comparing the efficacy of SYMBRAVO to oral CGRPs in the acute treatment of migraine. Corporate Update In March 2025 , Axsome announced that it resolved patent litigation with Hikma Pharmaceuticals USA, Inc. ( Hikma ) related to Hikma’s Abbreviated New Drug Application (ANDA) for a generic version of SUNOSI. The Company entered into a license and settlement agreement with Hikma , which permits Hikma to begin selling its generic version of SUNOSI on or after September 1, 2040 , if pediatric exclusivity is granted, or on or after March 1, 2040 , if no pediatric exclusivity is granted, subject to FDA approval and conditions and exceptions customary for agreements of this type.
