PLYMOUTH MEETING, Pa., April 24, 2023 /PRNewswire/ -- Harmony Biosciences Holdings, Inc. ("Harmony" or the "Company") (Nasdaq: HRMY), a pharmaceutical company dedicated to developing and commercializing innovative therapies for patients with rare neurological diseases, today announced that Jeffrey M. Dayno, M.D., has been appointed President and Chief Executive Officer by the Company's Board of Directors and has been elected to join as a member of the Board.

Dr. Dayno joined Harmony as Chief Medical Officer and Executive Vice President when the company was founded in 2017 and has been serving as Interim President and CEO since January 6, 2023.

Harmony Board Chairman, Jeff Aronin, noted that Dr. Dayno, a nationally recognized neuroscience expert, has been a valuable member of the Company's inaugural executive management team since 2017. He played a critical role in the FDA approval of Harmony's key asset, WAKIX® (pitolisant), and helped to shape commercial strategy.  

"Dr. Dayno has been an influential leader since day one. The Board unanimously appointed him President and CEO because it firmly believes in his vision for ongoing strong growth in critical areas of the business," said Mr. Aronin. "We believe he will continue to expand the WAKIX franchise in narcolepsy, pursue new indications for patients and advance the pipeline of new assets. That is a clear path to short- and long-term value for Harmony's shareholders."

With the appointment, Mr. Aronin returns to serving as non-executive Chairman of the Board. Dr. Dayno expressed appreciation for the Board's confidence in his leadership.

"After 12 years as a practicing neurologist taking care of patients, followed by 25 years in the industry touching every aspect of the business, I have seen the impact that developing and delivering innovative treatments can have on patients and their families. I am honored that the Board has asked me to lead the company forward in our next phase of growth," said Dr. Dayno. "We are confident in WAKIX being a potential $1 billion-plus narcolepsy opportunity, with the potential to contribute up to an additional $1 billion if approved in idiopathic hypersomnia and other current lifecycle management programs. I am passionate about leading the company forward and will focus on advancing our lifecycle management programs and acquiring new assets to build out our pipeline."

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 and 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 

Contraindications 
WAKIX is contraindicated in patients with known hypersensitivity to pitolisant or any component of the formulation. Anaphylaxis has been reported. WAKIX is also contraindicated in patients with severe hepatic impairment.  

Warnings and Precautions 
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 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 (see full prescribing information). WAKIX is not recommended in patients with end-stage renal disease (ESRD). 

Adverse Reactions 
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. 

Drug Interactions 
Concomitant administration of WAKIX with strong CYP2D6 inhibitors increases pitolisant exposure by 2.2-fold. Reduce the dose of WAKIX by half.  

Concomitant use of WAKIX with strong CYP3A4 inducers decreases exposure of pitolisant by 50%. Dosage adjustments may be required (see full prescribing information).  

H1 receptor antagonists that cross the blood-brain barrier may reduce the effectiveness of WAKIX. Patients should avoid centrally acting H1 receptor antagonists.  

WAKIX is a borderline/weak inducer of CYP3A4. Therefore, reduced effectiveness of sensitive CYP3A4 substrates may occur when used concomitantly with WAKIX. The effectiveness of hormonal contraceptives may be reduced when used with WAKIX and effectiveness may be reduced for 21 days after discontinuation of therapy. 

Use in Specific Populations 
WAKIX may reduce the effectiveness of hormonal contraceptives. Patients using hormonal contraception should be advised to use an alternative non-hormonal contraceptive method during treatment with WAKIX and for at least 21 days after discontinuing treatment.  

There is a pregnancy exposure registry that monitors pregnancy outcomes in women who are exposed to WAKIX during pregnancy. Patients should be encouraged to enroll in the WAKIX pregnancy registry if they become pregnant. To enroll or obtain information from the registry, patients can call 1-800-833-7460. The safety and effectiveness of WAKIX have not been established in patients less than 18 years of age.  

WAKIX is extensively metabolized by the liver. WAKIX is contraindicated in patients with severe hepatic impairment. Dosage adjustment is required in patients with moderate hepatic impairment. 

WAKIX is not recommended in patients with end-stage renal disease. Dosage adjustment of WAKIX is recommended in patients with moderate or severe renal impairment.  

Dosage reduction is recommended in patients known to be poor CYP2D6 metabolizers; these patients have higher concentrations of WAKIX than normal CYP2D6 metabolizers. 

Please see the Full Prescribing Information for WAKIX for more information.
