Designation offers potential for expedited development and review
FDA Orphan Drug Designation previously granted to Axsome for AXS-12 in narcolepsy
Third FDA Breakthrough Therapy designation received by Axsome
NEW YORK, Aug. 05, 2020 (GLOBE NEWSWIRE) -- Axsome Therapeutics, Inc. (NASDAQ: AXSM), a biopharmaceutical company developing novel therapies for the management of central nervous system (CNS) disorders, today announced that the U.S. Food and Drug Administration (FDA) has granted Breakthrough Therapy designation for AXS-12 for the treatment of cataplexy in patients with narcolepsy. AXS-12 is a novel, oral, highly selective and potent norepinephrine reuptake inhibitor. Axsome previously received Orphan Drug Designation from the FDA for AXS-12 for the treatment of narcolepsy. Narcolepsy is a debilitating, neurological condition characterized by excessive daytime sleepiness (EDS) and cataplexy, a sudden loss of muscle tone triggered by strong emotions.
A Breakthrough Therapy designation is granted to potentially expedite development and review timelines for a promising investigational medicine when preliminary clinical evidence indicates it may demonstrate substantial improvement on one or more clinically significant endpoints over available therapies for a serious or life-threatening condition. The Breakthrough Therapy designation for AXS-12 for the treatment of cataplexy in narcolepsy was supported by the positive results from the Phase 2 CONCERT study, a randomized, double-blind, placebo-controlled, crossover, multicenter U.S. trial. In the trial, 21 patients with a diagnosis of narcolepsy with cataplexy were treated for 2 weeks with AXS-12 or with placebo, followed by a crossover to the other treatment after a 1-week down-titration and washout period. AXS-12 met the primary endpoint demonstrating a highly statistically significant reduction from baseline in the mean weekly number of cataplexy attacks, averaged for the 2-week treatment period (overall treatment effect), as compared to placebo (p<0.001), and at the end of the 2-week treatment period (p=0.002). AXS-12 also significantly improved EDS compared to placebo, as measured by the Epworth Sleepiness Scale (ESS) and by the frequency of inadvertent naps (p=0.003 and p<0.001, respectively). In addition, AXS-12 significantly improved cognitive function compared to placebo over the 2-week treatment period as measured by the Ability to Concentrate item of the Narcolepsy Symptom Assessment Questionnaire (p<0.001). AXS-12 was well tolerated in this trial with the most commonly reported adverse events being anxiety, constipation, and insomnia.
“This FDA Breakthrough Therapy designation for AXS-12 for cataplexy in narcolepsy highlights its potential, should it be successfully developed, to provide meaningful benefit and substantial improvement over currently available treatment options for patients living with this debilitating condition. We are excited by the burgeoning profile of AXS-12 which has also received Orphan Drug designation for the treatment of narcolepsy,” said Herriot Tabuteau, MD, Chief Executive Officer of Axsome. “Axsome has now received three FDA Breakthrough Therapy designations, including designations for AXS-05 in major depressive disorder and for AXS-05 in Alzheimer’s disease agitation. These designations exemplify our commitment to developing potentially life-changing medicines for patients with difficult-to-treat CNS conditions, our innovative approach to clinical development, and our resulting differentiated and broad late-stage CNS pipeline. We look forward to meeting with the FDA as soon as possible to discuss the continued development of AXS-12 in light of this significant milestone.”
About FDA Breakthrough Therapy Designation
Breakthrough Therapy designation is granted by the FDA in order to expedite the development and review of drugs for serious or life-threatening conditions. In order to receive Breakthrough Therapy designation, a drug must demonstrate preliminary clinical evidence that the drug may have substantial improvement on at least one clinically significant endpoint over available therapy. Breakthrough Therapy designation provides an organizational commitment involving senior managers from the FDA, more intensive FDA guidance on an efficient drug development program, and greater access to and more frequent communication with the FDA throughout the entire drug development and review process. It also provides the opportunity to submit sections of a New Drug Application (NDA) on a rolling basis, where the FDA may review portions of the NDA as they are received instead of waiting for the entire NDA submission. In addition, Breakthrough Therapy designated products are eligible for Priority Review, where the FDA has a goal to take action on an application within six months, as opposed to ten months under standard review. Breakthrough Therapy designation does not change the standards for approval.
About Narcolepsy
Narcolepsy can be 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 highly selective and potent norepinephrine reuptake inhibitor 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) Breakthrough Therapy designation and Orphan Drug Designation for the treatment of narcolepsy. AXS-12 is an investigational drug product not approved by the FDA.
