Harmony Biosciences To Present WAKIX® (Pitolisant) Data At The 2021 AAN Annual Meeting

Rhea-AI Summary

Harmony Biosciences (Nasdaq: HRMY) announced that clinical results for WAKIX® (pitolisant) will be presented at the 2021 American Academy of Neurology Annual Meeting from April 17-22. These include two analyses: one on the time-to-onset of clinical response during treatment and another on the cardiovascular safety profile of WAKIX in narcolepsy patients. WAKIX, approved for treating excessive daytime sleepiness, has been available since Q4 2019. The meeting presentations aim to enhance understanding of WAKIX's efficacy and safety for patients with narcolepsy.

PLYMOUTH MEETING, Pa., April 12, 2021 /PRNewswire/ -- Harmony Biosciences Holdings, Inc. ("Harmony") (Nasdaq: 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 analyses from the clinical development program for WAKIX® (pitolisant) will be presented at the 2021 American Academy of Neurology (AAN) Annual Meeting, to be held virtually April 17-22. One of the poster presentations is based on a post-hoc analysis that evaluated the time-to-onset of clinical response for WAKIX and the second poster is based on a pooled analysis of the cardiovascular safety data from the clinical development program for WAKIX in adult patients with narcolepsy.

"These analyses further characterize the efficacy and safety profile of WAKIX and its broad clinical utility for the treatment of excessive daytime sleepiness or cataplexy in adult patients with narcolepsy," said Harmony's Chief Medical Officer, Jeffrey Dayno, M.D. "We look forward to sharing these data and the results of these analyses with both the neurology and narcolepsy communities."

The data that will be presented by Harmony will be available from 7 a.m.-5 p.m. EDT on April 17-22, and include:

• Time to Onset of Clinical Response During Treatment with Pitolisant (P26.015). C Davis, J Dayno, B Vaughn, Y Dauvilliers.
• Analysis evaluating the time-to-onset of clinical response during treatment with pitolisant for excessive daytime sleepiness and cataplexy from the HARMONY-1 and HARMONY-CTP randomized, controlled trials in adults with narcolepsy.
• Cardiac Safety Profile of Pitolisant in Patients with Narcolepsy (P26.016). W Winter, S Wanaski, A Patroneva, J Dayno.
• Results from pooled analysis of two randomized, placebo-controlled seven-or eight-week studies and from a 12-month, open-label study evaluating the cardiac safety profile of pitolisant in adults with narcolepsy from the clinical development program.

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. 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.
