Topline results anticipated in 2Q 2019

NEW YORK, NY, USA I January 30, 2019 I Axsome Therapeutics, Inc. (NASDAQ: AXSM), a clinical-stage biopharmaceutical company developing novel therapies for the management of central nervous system (CNS) disorders, has initiated the CONCERT (Clinical Outcomes in Narcolepsy and Cataplexy: An Evaluation of Reboxetine Treatment) study, a Phase 2, randomized, controlled trial of AXS-12 (reboxetine) in narcolepsy. AXS-12 has been granted Orphan Drug Designation by the U.S. Food and Drug Administration (FDA) for the treatment of narcolepsy. Topline results from the CONCERT trial are expected in the second quarter of 2019.

“The initiation of the CONCERT trial of AXS-12 for the treatment of narcolepsy reflects Axsome’s advancing pipeline of differentiated CNS product candidates, and our continued commitment to developing novel medicines to improve the lives of patients living with serious and difficult-to-treat CNS disorders,” said Herriot Tabuteau, MD, Chief Executive Officer of Axsome. “The CONCERT trial utilizes an efficient crossover design to improve signal detection and speed trial conduct. We look forward to topline results from this study in the second quarter of this year.”   

“Narcolepsy is debilitating for the nearly 200,000 individuals living with this condition in the U.S. Unfortunately, treatment options for these patients are limited,” said Cedric O’Gorman, MD, Senior Vice President of Clinical Development and Medical Affairs of Axsome. “AXS-12 has the potential to address the key symptoms of this disorder and may not share the limitations of currently approved agents. We look forward to evaluating the potential of AXS-12 in the CONCERT trial, with the goal of providing a more effective treatment for narcolepsy.”

About the CONCERT Trial
CONCERT (Clinical Outcomes in Narcolepsy and Cataplexy: An Evaluation of Reboxetine Treatment) is a Phase 2, double-blind, randomized, placebo-controlled, crossover, multicenter trial of AXS-12 in patients with narcolepsy. The study will enroll approximately 20 patients, all of whom will be treated with AXS-12 for three weeks, and with placebo for three weeks. Eligible patients will be randomized to receive either AXS-12 followed by placebo, or placebo followed by AXS-12. Efficacy assessments will include the frequency of cataplexy attacks, and measures of other symptoms of narcolepsy.

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. Depression is reported in up to 57% of patients.

About AXS-12
AXS-12 (reboxetine) is a novel, oral, investigational medicine in development for the treatment of the symptoms of narcolepsy. AXS-12 is a highly selective and potent norepinephrine reuptake inhibitor. AXS-12 is an investigational drug product not approved by the FDA.
