ROCKVILLE, Md., May 05, 2020 (GLOBE NEWSWIRE) -- Supernus Pharmaceuticals, Inc. (Nasdaq: SUPN), a pharmaceutical company focused on developing and commercializing products for the treatment of central nervous system (CNS) diseases, today reported financial results for the first quarter of 2020 and associated Company developments

Commercial Update

First quarter 2020 product prescriptions for Trokendi XR^® and Oxtellar XR^®, as reported by IQVIA, totaled 203,404, a 2% increase over first quarter 2019.

	Prescriptions
	Q1 2020			Q1 2019			Change %
Trokendi XR	160,315			160,940			—	%
Oxtellar XR	43,089			38,580			12	%
Total	203,404			199,520			2	%

Source: IQVIA

First quarter 2020 net product sales were $92.5 million, an increase of 11% over $83.1 million in the first quarter of 2019. As previously disclosed, wholesalers, distributors, and pharmacies decreased their inventory levels of the Company's products in the first quarter of 2019. The Company estimates that this caused net product sales in the first quarter of 2019 to be approximately $10 million lower had inventory levels remained constant, thus favorably impacting year over year net product sales growth in the first quarter of 2020.

	Net Product Sales ($ in millions)
	Q1 2020				Q1 2019				Change %
Trokendi XR	$	68.6			$	63.7			8	%
Oxtellar XR	23.9				19.4				23	%
Total	$	92.5			$	83.1			11	%

Supply of Trokendi XR and Oxtellar XR has not been impacted by COVID-19. The Company has adequate inventory on hand for both products to continue to be available to patients.

Corporate and Product Pipeline Update

SPN-812 - Novel non-stimulant for the treatment of ADHD

• The Company continues to prepare for the commercial launch of SPN-812 at the end of 2020.
• The Company remains engaged with the U.S. Food and Drug Administration (FDA) regarding its New Drug Application (NDA) for SPN-812 for the treatment of ADHD, which has a Prescription Drug User Fee Act (PDUFA) target action date of November 8, 2020.
• The Phase III program in adult patients reached approximately 75% of the targeted enrollment before additional enrollment was put on hold in March 2020 due to the impact of COVID-19. The Company is employing virtual efforts to ensure that currently enrolled subjects can progress to completion of treatment. This trial was ahead of schedule prior to the COVID-19 pandemic, with a potential data release in the second half of this year. Depending on when the Company can restart enrollment and complete the study, data from the trial may be pushed into 2021.

CNS portfolio of US WorldMeds

• As announced last week, Supernus entered into a definitive Sale and Purchase Agreement to acquire the CNS portfolio of US WorldMeds, a privately-held biopharmaceutical company. The acquisition is expected to close in the second quarter of 2020, subject to certain conditions, including the expiration of the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act and other customary conditions.
• US WorldMeds’ CNS portfolio consists of three marketed products with 2019 net sales and operating earnings of approximately $150 million and $45 million, respectively, and a product candidate with an expected NDA submission in the second half of 2020.
• The acquisition expands and strengthens the Company's neurology portfolio, diversifies its revenue and operating cash flow base and enhances long term growth.
• Total consideration consists of an upfront cash payment of $300 million plus regulatory and commercial milestone cash payments up to $230 million. All cash consideration will be funded through existing balance sheet cash.

SPN-820 (NV-5138) – novel first-in-class activator of mTORC1

• Supernus and Navitor Pharmaceuticals, Inc., a privately-held company, announced a joint Development and Option Agreement for Navitor’s mTORC1 activator, NV-5138.
• Supernus and Navitor will jointly conduct a Phase II clinical program for NV-5138 in treatment-resistant depression. Supernus will pay up to $50 million of the costs of Phase II development, plus certain costs associated with nonclinical development and formulation.
• In addition, Navitor has granted Supernus an exclusive, worldwide (excluding Greater China) option to license or acquire NV-5138 prior to initiation of a Phase III clinical program. In exchange for the option to license or acquire NV-5138, Navitor will receive an upfront payment of $25 million, composed of a $10 million option fee and a $15 million equity investment. The equity investment represents an approximately 13% ownership in Navitor. Total payments, exclusive of royalty payments on net sales of NV-5138 and development costs under the agreement, have the potential to reach $410 million to $475 million, which includes the upfront payment, an additional license or acquisition fee depending on whether Supernus ultimately licenses or acquires NV-5138, and subsequent clinical, regulatory and sales milestone payments.
• Supernus also will have the first right of refusal for any compound with a similar mechanism of action on mTORC1 as NV-5138 in the central nervous system.

SPN-604 - Novel treatment of bipolar disorder

• The Company has reprioritized its research and development (R&D) resources following recent expansion of the product pipeline through mid to late-stage development product candidates. These product candidates include SPN-820 from the Navitor partnership and Apomorphine Infusion Pump from the US WorldMeds transaction. As a result, and given other factors including the estimated timing of a potential launch of SPN-604 and the required investment, the Company is terminating development of SPN-604 for the treatment of bipolar disorder.

Sales and marketing infrastructure

• The acquisition of the CNS product portfolio from US WorldMeds includes a sales force of approximately 46 sales representatives that focuses on serving movement disorder specialists in the U.S.
• The Company continues to plan on adding salesforce personnel toward the end of 2020 in anticipation of the launch of SPN-812. 

“The two business development transactions that we announced over the last couple of weeks strengthen our product portfolio and late-stage pipeline, diversify our revenue base, enhance our long term growth, and strengthen our leadership position in CNS,” said Jack Khattar, President and CEO of Supernus. “In addition, they expand our commercial and R&D platforms into the biologics, orphan disease and specialty pharmacy areas.”

Operating Expenses

R&D expenses in the first quarter of 2020 were $18.9 million, compared to $15.4 million in the same quarter last year. This increase was primarily driven by enrollment in the SPN-812 Phase III program for adults, initiated in late 2019.

SG&A expenses in the first quarter of 2020 were $42.9 million, compared to $41.0 million in the same quarter last year. This increase was primarily driven by pre-launch activities associated with SPN-812, partially offset by a decrease in marketing expenses for commercial products and a decrease in employee-related expenses.

Operating Earnings and Earnings Per Share

Operating earnings in the first quarter of 2020 were $29.0 million, compared to $25.4 million in the first quarter of 2019. The increase of $3.6 million was primarily due to increased revenue from our two commercial products.

Net earnings (GAAP) in the first quarter of 2020 were $21.5 million, or $0.40 per diluted share, an increase of 18% on a diluted share amount, as compared to $18.3 million, or $0.34 per diluted share, in the same period last year.

Weighted-average diluted common shares outstanding were approximately 53.6 million for the first quarter of 2020, as compared to approximately 54.0 million for the prior year period.

Balance Sheet Highlights

As of March 31, 2020, the Company had $935.6 million in cash, cash equivalents, marketable securities and long term marketable securities, compared to $938.8 million at December 31, 2019. This decrease was primarily attributable to unrealized losses on long term marketable securities resultant from market volatility in the first quarter of 2020.

Financial Guidance

Given the uncertainty caused by the COVID-19 pandemic, the anticipated second quarter acquisition of the CNS portfolio from US WorldMeds and the impact of the partnership with Navitor Pharmaceuticals, the Company is suspending its previously issued full year 2020 financial guidance. The Company expects to update and reinstate full year 2020 guidance no later than the announcement of second quarter 2020 financial results in August.

The Company will hold a conference call hosted by Jack Khattar, President and Chief Executive Officer, and Greg Patrick, Senior Vice President and Chief Financial Officer, to discuss these results at 9:00 a.m. Eastern Time, on Wednesday, May 6, 2020.
