Harmony Biosciences Holdings Inc presented data from three analyses of the clinical development program for WAKIX (pitolisant), a medication approved for the treatment of excessive daytime sleepiness or cataplexy in adults with narcolepsy, at the 2021 American Psychiatric Association (APA) Annual Meeting, held virtually May 1-3.
This is the first time Harmony has shared WAKIX data directly with the psychiatry and mental health professional communities. Sleep disorders are highly comorbid with a multitude of psychiatric disorders and narcolepsy can have a significant impact on a person’s daily functioning, which may greatly affect their social, emotional and psychological well-being, and quality of life.
Two of the three poster presentations feature analyses of efficacy and safety data from the clinical development program for WAKIX in adult patients with narcolepsy and the third is based on a post-hoc analysis that evaluated the time to onset of clinical response for WAKIX.
“Both excessive daytime sleepiness and cataplexy can have a significant impact on a person’s daily functioning, which may greatly affect their social, emotional, and psychological well-being,” says Harmony’s chief medical officer, Jeffrey Dayno, MD, in a release. “Given this, and the fact that sleep disorders are comorbid with several different psychiatric disorders, we are pleased to share these data for WAKIX with the psychiatry and mental health professional communities for the first time.”
