· Issued by Harmony Biosciences Holdings, Inc. via Business Wire

PLYMOUTH MEETING, Pa.--(BUSINESS WIRE)-- Harmony Biosciences Holdings, Inc. (Nasdaq: HRMY), today announced the appointment of Adam Zaeske as Executive Vice President and Chief Commercial Officer (CCO), effective March 31, 2025. The company’s current CCO, Jeffrey Dierks, is voluntarily stepping down for personal reasons.

Zaeske brings 25 years of global leadership across the pharmaceutical industry, building teams and transforming organizations in both the U.S. and Europe. He has broad functional experience spanning commercial strategy and operations, sales, marketing, market access, new product planning and finance. At Harmony, Zaeske will be responsible for leading the company’s commercial organization, setting commercial strategy, driving market expansion in the U.S. and abroad, and ensuring strong execution across all brands and geographies. His deep expertise in launching products, including in rare diseases, coupled with his extensive experience in scaling commercial operations and embedding strong capabilities, will be pivotal as Harmony builds on the commercial success of WAKIX® (pitolisant) and prepares to advance its late-stage pipeline assets toward approvals both in the U.S. and other territories to serve even more patients worldwide.

“I am very excited to welcome Adam to the team as we build upon the commercial success of WAKIX in narcolepsy and prepare for our next phase of growth,” said Jeffrey M. Dayno, M.D., President and Chief Executive Officer of Harmony Biosciences. “As Harmony continues to execute on our growth strategy, Adam’s deep commercial expertise, proven leadership across both the US and international markets, and experience launching and growing brands, including in rare diseases, make him the ideal person to lead our Commercial team and drive our next phase of growth. I also want to express my gratitude to Jeffrey Dierks for his contributions in building Harmony’s strong commercial foundation and leading the successful launch and commercialization of WAKIX. With this foundation, we remain confident in our 2025 revenue guidance and in WAKIX being a $1B plus opportunity in adult narcolepsy alone.”

Zaeske most recently served as Head of Central, South, and Eastern Europe at Takeda Pharmaceuticals, where he managed a $2 billion business spanning 25 countries and nearly 900 employees. Under his leadership, the region delivered three consecutive years of double-digit growth and contributed the largest portion of revenue and growth for Takeda’s European and Canadian business. Zaeske has also successfully led commercial organizations in the U.S. and Europe across multiple therapeutic areas, including rare diseases, neuroscience, immunology, hematology, oncology and gastroenterology, ensuring patient access to innovative therapies and driving long-term portfolio growth. Zaeske holds an MBA from Harvard Business School and graduated with honors from the University of Michigan with a degree in Business Administration and Finance.

“I am impressed by the Harmony team, their clarity of purpose in helping people living with rare neurological diseases, and the success of WAKIX in narcolepsy,” said Zaeske. “I am very excited to be joining the organization at such a pivotal time with the opportunity to expand on that success with the next-generation pitolisant formulations as well as the late-stage products in their robust pipeline as they advance toward commercialization. My experiences in both rare disease and neurology were tremendously rewarding parts of my career, and I look forward to returning to these therapeutic areas and contributing to Harmony’s potential to help many more patients who are living with unmet medical needs.”

Zaeske’s appointment comes as Harmony’s portfolio is poised for significant growth, driven by a catalyst-rich pipeline with late-stage assets that have global rights, and strategic initiatives designed to expand its reach of innovative products to patients around the world.

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 (EDS) or cataplexy in adult patients with narcolepsy and for the treatment of EDS in pediatric patients 6 years of age and older with narcolepsy. 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.

Indications and Usage

WAKIX is indicated for the treatment of excessive daytime sleepiness (EDS) or cataplexy in adult patients with narcolepsy and for the treatment of excessive daytime sleepiness (EDS) in pediatric patients 6 years of age and older with narcolepsy.

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. WAKIX is contraindicated in patients with severe hepatic impairment and 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 at least 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 tract infection, musculoskeletal pain, heart rate increased, hallucinations, irritability, abdominal pain, sleep disturbance, decreased appetite, cataplexy, dry mouth, and rash.

In the placebo-controlled phase of the clinical trial conducted in pediatric patients 6 years and older with narcolepsy with or without cataplexy, the most common adverse reactions (≥5% and greater than placebo) for WAKIX were headache (19%) and insomnia (7%). The overall adverse reaction profile of WAKIX in the pediatric clinical trial was similar to that seen in the adult clinical trial program.

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.

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. WAKIX may reduce the effectiveness of sensitive CYP3A4 substrates, including 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.

Use in Specific Populations

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 for treatment of excessive daytime sleepiness in pediatric patients less than 6 years of age with narcolepsy.

The safety and effectiveness of WAKIX have not been established for treatment of cataplexy in pediatric patients with narcolepsy.

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 eGFR
