PLYMOUTH MEETING, Pa., June 7, 2021 /PRNewswire/ -- Harmony Biosciences Holdings, Inc. ("Harmony") HRMY, a pharmaceutical company dedicated to developing and commercializing innovative therapies for patients living with rare neurological disorders who have unmet medical needs, today announced that results from two post-hoc analyses from the clinical development program for WAKIX® (pitolisant) will be presented at the 35th Annual Meeting of the Associated Professional Sleep Societies (APSS), known as "SLEEP 2021." The meeting will be held virtually June 10-13.
One of the poster presentations is a new analysis that calculated the number needed to treat (NNT) and effect size of WAKIX to demonstrate the magnitude of its clinical effectiveness. The second poster is based on an analysis of the cataplexy data from the clinical development program for WAKIX.
"The analyses that we are presenting at the SLEEP conference this year highlight the strength of the efficacy data for WAKIX," said Harmony's Chief Medical Officer, Jeffrey Dayno, M.D. "The analyses include both a traditional approach to presenting efficacy data, as well as one that underscores the clinical relevance of the findings, using NNT and effect sizes to capture overall clinical benefit."
The data being presented by Harmony will be available in the meeting's ePoster gallery beginning June 9 through November 30, and includes:
- Assessment of the Clinical Benefits of Pitolisant on Excessive Daytime Sleepiness and Cataplexy in Adults With Narcolepsy (Poster 504). Meskill, G, Davis, C, Zarycranski, D, Doliba, M, Schwartz JC, Dayno, J.
- Analysis evaluating number needed to treat and effect sizes for treatment with pitolisant for excessive daytime sleepiness and cataplexy from the HARMONY-1 and HARMONY-CTP randomized, controlled, 7- or 8-week trials in adults with narcolepsy.
- Efficacy of Pitolisant in the Treatment of Cataplexy in Adults With Narcolepsy (Poster 505). Davis, C, Zarycranski, D, Doliba, M, Dayno, J, Schwartz, JC.
- Analysis evaluating the frequency of cataplexy attacks during treatment with pitolisant from the HARMONY-1 and HARMONY-CTP randomized, controlled, 7- or 8-week trials in adults with narcolepsy.
About WAKIX® (pitolisant) Tablets
WAKIX, a first-in-class medication, is approved by the U.S. Food and Drug Administration for the treatment of excessive daytime sleepiness or cataplexy in adult patients with narcolepsy. WAKIX has been commercially available in the U.S. since Q4 2019. It was granted orphan drug designation for the treatment of narcolepsy in 2010, and breakthrough therapy designation for the treatment of cataplexy in 2018. WAKIX is a selective histamine 3 (H3) receptor antagonist/inverse agonist. The mechanism of action of WAKIX is unclear; however, its efficacy could be mediated through its activity at H3 receptors, thereby increasing the synthesis and release of histamine, a wake promoting neurotransmitter. WAKIX was designed and developed by Bioprojet (France). Harmony has an exclusive license from Bioprojet to develop, manufacture and commercialize pitolisant in the United States.
Important Safety Information
WAKIX is contraindicated in patients with known hypersensitivity to pitolisant or any component of the formulation and in patients with severe hepatic impairment. WAKIX is extensively metabolized by the liver and there is a significant increase in WAKIX exposure in patients with moderate impairment.
WAKIX prolongs the QT interval. Avoid use of WAKIX in patients with known QT prolongation or in combination with other drugs known to prolong the QT interval. Avoid use of WAKIX in patients with a history of cardiac arrhythmias, as well as other circumstances that may increase the risk of the occurrence of torsade de pointes or sudden death, including symptomatic bradycardia, hypokalemia or hypomagnesemia, and the presence of congenital prolongation of the QT interval.
The risk of QT prolongation may be greater in patients with hepatic or renal impairment due to higher concentrations of pitolisant; monitor these patients for increased QTc. Dosage modification is recommended in patients with moderate hepatic impairment and moderate or severe renal impairment. WAKIX is not recommended in patients with end-stage renal disease (ESRD).
In the placebo-controlled clinical trials conducted in patients with narcolepsy with or without cataplexy, the most common adverse reactions (≥5% and twice placebo) for WAKIX were insomnia (6%), nausea (6%), and anxiety (5%). Other adverse reactions that occurred at ≥2% and more frequently than in patients treated with placebo included headache, upper respiratory infection, musculoskeletal pain, heart rate increased, hallucinations, irritability, abdominal pain, sleep disturbance, decreased appetite, cataplexy, dry mouth, and rash.

About Narcolepsy
Narcolepsy is a rare, chronic, debilitating neurological disorder of sleep-wake state instability that impacts approximately 165,000 Americans and is primarily characterized by excessive daytime sleepiness (EDS) and cataplexy – its two cardinal symptoms – along with other manifestations of REM sleep dysregulation, which intrude into wakefulness. EDS is the inability to stay awake and alert during the day and is the symptom that is present in all people living with narcolepsy. In most patients, narcolepsy is caused by the loss of hypocretin, a neuropeptide in the brain that supports sleep-wake state stability. This disorder affects men and women equally, with typical symptom onset in adolescence or young adulthood; however, it can take up to a decade to be properly diagnosed.
