About the SYMPHONY Trial

SYMPHONY (Study Evaluating a Mechanistic Approach to Treating Narcolepsy) is a Phase 3, randomized, double-blind, multicenter, placebo-controlled trial to assess the efficacy and safety of AXS-12 in patients with narcolepsy. Approximately 90 patients will be randomized in a 1:1 ratio to treatment with AXS-12 or placebo for 5 weeks. The primary endpoint will be the frequency of cataplexy attacks. Other symptoms of narcolepsy as well as safety will be assessed throughout the study.

About Narcolepsy

Narcolepsy is a serious and debilitating neurological condition that causes dysregulation of the sleep-wake cycle and is characterized clinically by excessive daytime sleepiness, cataplexy, hypnagogic hallucinations, sleep paralysis, and disrupted nocturnal sleep. Narcolepsy afflicts an estimated 185,000 individuals in the U.S. Cataplexy is seen in an estimated 70% of narcolepsy patients and is a sudden reduction or loss of muscle tone while a patient is awake, typically triggered by strong emotions such as laughter, fear, anger, stress, or excitement. Narcolepsy interferes with cognitive, psychological, and social functioning, increases the risk of work- and driving-related accidents, and is associated with a 1.5-fold higher mortality rate.

About AXS-12

AXS-12 (reboxetine) is a highly selective and potent norepinephrine reuptake inhibitor under development for the treatment of narcolepsy. AXS-12 modulates noradrenergic activity to promote wakefulness, maintain muscle tone and enhance cognition. AXS-12 has been granted U.S. Food and Drug Administration (FDA) Orphan Drug Designation for the treatment of narcolepsy. AXS-12 is an investigational drug product not approved by the FDA.
