Conference Call and Webcast Today at 8:30 a.m. ET

PLYMOUTH MEETING, Pa., Nov. 04, 2026 (GLOBE NEWSWIRE) -- Harmony Biosciences Holdings, Inc. (Nasdaq: HRMY), today reported third quarter 2026 financial results and preliminary data from its multiple-ascending dose (MAD) clinical study for its potential best-in-class orexin agonist BP-205. WAKIX^® (pitolisant) delivered third quarter net revenue of $269 million, driven by strong demand of 400 net patient adds, and the Company remains on track to achieve full-year WAKIX net revenue guidance of $1.0 billion to $1.04 billion.

The encouraging preliminary results from the MAD study with BP-205, following 14 days of repeated once-daily dosing, reinforce the favorable safety, tolerability and pharmacokinetic profile observed in the single-ascending dose (SAD) portion of the study. No liver or visual adverse events were reported, and no clinically significant cardiovascular events or EKG abnormalities were recorded. Harmony remains on track to report Phase 1b data in sleep-deprived healthy volunteers in the first quarter of 2027, followed by the initiation of Phase 2 studies across multiple CNS indications by mid-2027.

Additionally, as announced on October 12, 2026, Peter Anastasiou, Senior Executive Vice President and Chief Operating Officer, will become President and Chief Executive Officer effective January 1, 2027, succeeding Jeffrey Dayno, MD, who will retire on December 31, 2026. This planned leadership transition does not change Harmony's previously communicated strategic priorities or the expected timing of key commercial and pipeline milestones.

“As I prepare to transition the President and CEO role to Peter on January 1, I believe Harmony is operating from a position of strength, with a durable and growing WAKIX franchise, the financial flexibility to invest in innovation, conviction to pursue strategic business development opportunities, and a pipeline led by BP-205 that has the potential to generate significant long-term value,” said Jeffrey Dayno, MD, President and Chief Executive Officer of Harmony Biosciences. “I am proud of the talented team and passionate organization we have built, which position Harmony for continued success in delivering innovative treatments to patients and sustained value for our shareholders.”

Key Drivers of Value Creation

Continued WAKIX Growth in an Evolving Market

Third Quarter 2026 Net Product Revenue for WAKIX

• WAKIX net revenue for the quarter ended September 30, 2026, was $268.9 million, driven by strong patient demand:
  • Estimated average number of patients grew by 400 to 9,350 in Q3, continuing strong recent performance with 5 of the last 6 quarters achieving more than 400 patient additions
  • Executed expansion of field sales, remote sales, field reimbursement and patient outreach teams with all roles hired, trained and fully deployed in Q2
• Growth continues to be demand driven: WAKIX is the only non-scheduled treatment option for excessive daytime sleepiness and cataplexy in adult and pediatric patients with narcolepsy type 1 and 2, supported by more than seven years of clinical experience and coverage for more than 80% of covered lives
• Significant market opportunity remains: approximately 170,000 people in the U.S. are living with narcolepsy, fewer than 50% are diagnosed, and brand penetration is approximately 20%
  
  

On Track to Achieve 2026 WAKIX Net Revenue Guidance of $1.0 Billion to $1.04 Billion

Advance Robust, Self-Funded Pipeline

BP-205 (Orexin-2 receptor agonist)

BP-205 MAD Study Design and Preliminary Results

• 14-day double-blind, randomized, placebo-controlled study that evaluated once-daily doses of BP-205 at 0.1 mg, 0.6 mg, 1 mg, and 3 mg across six cohorts (4 male and 2 female); a total of 94 healthy volunteers participated in this study
• BP-205 was rapidly absorbed, with a mean T_(max) of approximately 60 minutes (range 30 to 90 minutes) supportive of the potential for rapid onset of efficacy
• The mean effective half-life (T_1/2) after 14-day repeat dosing was observed to be approximately 29 hours; no clinically meaningful change compared to the half-life in the SAD study and supportive of once-daily dosing
• BP-205 was generally well tolerated across all doses evaluated: headache was the most common adverse event occurring in approximately 25% of participants
• On-target adverse events of insomnia were reported in less than 20% of participants at all doses evaluated, were mild in severity and did not lead to discontinuation
• On-target adverse events of urinary frequency and urgency were reported in less than 20% of participants at the 1mg and 3mg doses only; these events were mild in severity and did not lead to discontinuation
• No liver or visual adverse events were reported, and no clinically significant cardiovascular events or EKG abnormalities were recorded
• There were no serious or severe adverse events
• The complete MAD study results will be presented at an upcoming medical meeting
• Next steps in BP-205 development:
  • Phase 1b study in sleep-deprived healthy volunteers initiated in Q3 in the US; data expected in Q1 2027
  • Expect to initiate Phase 2 studies to evaluate multiple CNS indications by mid-2027
• Poster presented by Bioprojet at the SLEEP EU 2026 meeting showed an in-vivo synergistic effect of orexin and histamine on wakefulness in a narcoleptic mouse model; this suggests concomitant use of an orexin-2 agonist and pitolisant as a potential therapeutic approach for patients with central disorders of hypersomnolence

• BP-205, Harmony’s investigational OX2R agonist, was discovered by Teijin Pharma and is being developed in partnership with Bioprojet
  
  

Pitolisant GR (gastro-resistant) Tablets: On track to launch in 1H 2027

• NDA accepted by the FDA with PDUFA date of April 1, 2027
  • Enables patients to initiate treatment at a therapeutic dose without titration, an important clinical differentiation
• Utility patents filed to extend pitolisant franchise into the 2040s
  
  

Pitolisant HD (high dose): Opportunity to extend the pitolisant franchise with differentiated labeling

• Phase 3 registrational clinical trials ongoing in narcolepsy (ONSTRIDE 1) and idiopathic hypersomnia (IH) (ONSTRIDE 2):
  • Topline data expected in 2027 and anticipated PDUFA date in 2028
  • Enhanced formulation with optimized PK profile, enteric coating and higher dose to drive greater efficacy
  • Pursuing differentiated labeling: fatigue in narcolepsy and sleep inertia in IH
• Utility patents filed to extend pitolisant franchise into the 2040s
  
  

WAKIX (pitolisant): Phase 3 trial in Prader-Willi syndrome (PWS) (TEMPO)

• Topline data expected in mid-2027 and anticipated PDUFA date in 2028
• On track for pediatric exclusivity: completion of TEMPO study fulfills the second and last requirement agreed with FDA for WAKIX pediatric exclusivity, which would provide for an additional six months of regulatory exclusivity for WAKIX
  
  

Exploring amorphous form of pitolisant to pursue broader CNS indications

• This opportunity is based on our exclusive license to Novitium’s issued amorphous pitolisant patent with protection until 2042
• Continued efforts to optimize formulation and new modes of delivery
  
  

EPX-100 (clemizole hydrochloride)

• Actively enrolling in two Global Phase 3 registrational trials in rare epilepsies:
  • Lennox-Gastaut syndrome (LGS) – the LIGHTHOUSE Study
  • Dravet syndrome (DS) – the ARGUS Study
• Topline data expected in mid-2027 and anticipated PDUFA date in 2028
• Updated 18-month data from the open-label extension part of the ARGUS study to be presented at the American Epilepsy Society (AES) Annual Meeting in December 2026
  
  

Emphasis on Business Development

• Two categories of opportunity:
  • Assets that can add near-term revenue in 2028 to 2032 to support our self-funded model
  • Innovative pipeline assets that drive long-term value creation (e.g., BP-205)
• Therapeutic areas of interest include Sleep Disorders, Epilepsy, Rare/Orphan CNS, and broader CNS indications
• Supported by a strong balance sheet and clear conviction to execute on strategic business development opportunities
  
  

Protect the Pitolisant Franchise

• Multi-layered strategy: Harmony is asserting its pitolisant IP in active legal proceedings, with each case covering different components of our multi-layered IP strategy:
  • Polymorph and method of use ('197 and '947): The bench trial in the AET ANDA litigation closing arguments were held on October 22, 2026; ruling is expected around the time of the 30-month stay (February 2027)
  • Amorphous form ('920): Harmony Biosciences and Novitium filed a lawsuit alleging patent infringement in April against AET Pharma US and its marketing partner Sandoz; the licensed Novitium patent provides protection to 2042. A scheduling conference was held on October 21. The amorphous '920 patent trial has not yet been scheduled, but would be expected to be scheduled for some time in 2029
  • Yesterday, November 3, the judge scheduled a preliminary injunction hearing on January 26, 2027, with an expected decision by February 14, 2027 when the 30- month stay expires. This schedule is identical to the preliminary injunction schedule Harmony proposed to the judge on October 26
    
• In Q1 this year, we obtained the exclusive rights to a patent covering methods of making amorphous pitolisant hydrochloride from our licensee MSN Labs. That patent was issued by the PTO in Q3. The patent strengthens our patent portfolio and protects our development efforts for a new amorphous pitolisant hydrochloride product
• Together with settlements with 6 of the 7 ANDA filers, these actions reinforce Harmony's confidence in WAKIX exclusivity to March 2030 (inclusive of 6 months of pediatric exclusivity)
  
  

Third Quarter 2026 Financial Results

Harmony Biosciences reported WAKIX net revenue of $268.9 million for the quarter ended September 30, 2026, compared to $239.5 million for the quarter ended September 30, 2025, representing a 12% increase over the same period. This performance reflects continued strong demand for WAKIX within the large narcolepsy market opportunity (approximately 80,000 diagnosed patients in the U.S.), disciplined commercial execution across the franchise and the product's broad clinical utility. Based on our results for the first nine months of 2026, WAKIX remains on track to achieve full-year net revenue of $1.0 billion to $1.04 billion.

Cost of product sold was $80.7 million in the third quarter of 2026, or 30% as a percentage of WAKIX net revenue, as compared to $59.7 million, or 25%, for the same quarter in 2025, representing a 35% increase. The increase in cost of product sold as a percentage of net product revenue was primarily driven by new royalties related to the Novitium license agreement.

Net income for the third quarter was $48.2 million, or $0.81 per diluted share, compared to $50.9 million, or $0.87 per diluted share, for the same quarter in 2025. The decline in earnings was primarily driven by an increase in milestone charges and the new MSN royalty charges during the third quarter of 2026 as compared to the same quarter in 2025.

Harmony’s operating expenses include the following:

• Research and Development expenses were $71.7 million in the third quarter of 2026, as compared to $55.0 million for the same quarter in 2025, representing a 30% increase; this was primarily driven by a $25.0 million charge related to a milestone achieved for the MSN license agreement, partially offset by a $15.0 million charge related to a clinical milestone achieved for ZYN002 in the prior year period;
• Sales and Marketing expenses were $34.7 million in the third quarter of 2026, as compared to $29.5 million for the same quarter in 2025, representing an 18% increase, primarily driven by the expansion of our field-based teams;
• General and Administrative expenses were $27.7 million in the third quarter of 2026, as compared to $29.8 million for the same quarter in 2025, representing a 7% decrease; primarily driven by a decline in stock-based compensation expense; and
• Total Operating expenses were $134.0 million in the third quarter of 2026, as compared to $114.3 million for the same quarter in 2025, representing a 17% increase.
  
  

As of September 30, 2026, Harmony had cash, cash equivalents and investments of $1,051.6 million, compared to $882.5 million as of December 31, 2025.

Capital Allocation Priorities

• Invest in R&D pipeline, especially BP-205 development plan
• Success-based R&D milestone payments
• Strategic business development to expand pipeline and diversify commercial portfolio
