ROCKVILLE, Md., Nov. 03, 2021 (GLOBE NEWSWIRE) -- Supernus Pharmaceuticals, Inc. (Nasdaq: SUPN), a biopharmaceutical company focused on developing and commercializing products for the treatment of central nervous system (CNS) diseases, today reported financial results for the third quarter of 2021, and associated Company developments.

Net Product Sales

For the first nine months of 2021, net product sales were $412.5 million, a 12% increase over $368.6 million in the same period in 2020. The increase was primarily due to the acquisition of the CNS portfolio of US WorldMeds in June 2020.

Third quarter 2021 net product sales were $145.5 million, compared to $152.1 million in the same period in 2020. The decrease was primarily due to a decrease in net product sales of APOKYN and Trokendi XR, partially offset by an increase in net product sales from other products, including Qelbree, which was launched in the second quarter of 2021.

Qelbree Launch Update

• Qelbree's growth has accelerated with the arrival of the "back to school" season in the third quarter of 2021, reaching total monthly prescriptions in September of 7,132, an increase of 37% compared to August, and an increase of 118% compared to monthly average during the three months period prior to September. The latest weekly prescriptions data shows 2,248 prescriptions, an increase of 51% compared to the weekly average over the prior 12-week period.
• In addition, Qelbree's base of prescribers has increased by 340% during the third quarter of 2021 compared to the second quarter of 2021, with more than 3,470 physicians prescribing the product.

Proposed Acquisition of Adamas Pharmaceuticals, Inc. (Adamas)

• On October 11, 2021, the Company announced it entered into a definitive agreement to acquire Adamas, strengthening its Parkinson’s disease portfolio with two marketed products, including GOCOVRI^® (amantadine) extended release capsules, the first and only FDA-approved medicine indicated for the treatment of both "off" episodes and dyskinesia in patients with Parkinson’s disease receiving levodopa-based therapy. The acquisition, if completed, would strengthen Supernus' Parkinson’s disease portfolio with GOCOVRI and diversify and increase its revenue base and cash flow.
• Per the agreement, Supernus has offered to acquire all of Adamas’ common stock through a tender offer for $8.10 per share in cash (or an aggregate of approximately $400 million) payable at closing, plus two non-transferrable and non-tradable contingent value rights collectively worth up to $1.00 per share in cash (or an aggregate of approximately $50 million), for a total consideration of up to $9.10 per share in cash (or an aggregate of approximately $450 million). The transaction is subject to customary closing conditions and is expected to close in late fourth quarter 2021 or in early first quarter 2022.

Product Pipeline Update

Qelbree (viloxazine, extended-release capsules) - Novel non-stimulant for the treatment of ADHD in adults

• The U.S. Food and Drug Administration (FDA) acknowledged it has received the supplemental new drug application (sNDA) for Qelbree for the treatment of ADHD in adult patients. The sNDA has a user fee goal date (PDUFA date) of April 29, 2022.
  

SPN-830 (apomorphine infusion pump) - Continuous treatment of motor fluctuations (“on-off” episodes) in Parkinson's disease (PD)

• The Company expects to resubmit the SPN-830 NDA to the FDA in November 2021.
  

SPN-820 - Novel first-in-class activator of mTORC1

• An Investigational New Drug (IND) application was submitted to the FDA in September 2021. Consequently, the randomized Phase II clinical study of SPN-820 in treatment-resistant depression is on track and expected to start by the end of 2021.
  

SPN-817 – A novel product candidate for the treatment of epilepsy

• A randomized Phase II clinical study of SPN-817 for the treatment of focal seizures is expected to start in the second half of 2022.
