BOSTON, Feb. 27, 2019 (GLOBE NEWSWIRE) -- Paratek Pharmaceuticals, Inc. (Nasdaq: PRTK), a commercial-stage biopharmaceutical company focused on the development and commercialization of innovative therapeutics, today reported financial results and provided an update on corporate activities for the quarter and full year ended December 31, 2018.

“2018 was a transformative year for Paratek. The FDA approved NUZYRA, the first once-daily oral and IV antibiotic to treat both CABP and ABSSSI in nearly 20 years, as well as SEYSARA for the treatment of moderate to severe acne. Both products launched commercially in the U.S. earlier this year,” said Michael Bigham, Chairman and Chief Executive Officer, Paratek. “We believe that NUZYRA has the potential to shape the future treatment paradigm for serious community-acquired pneumonia and skin infections.”

“2019 will be an important year for Paratek,” said Evan Loh, M.D., President, Chief Operating Officer and Chief Medical Officer. “In addition to the U.S. launch of NUZYRA, we continue to pursue several compelling life-cycle opportunities including two phase 2 studies in UTI, collaborating with the Department of Defense for plague and anthrax and exploring the potential of an oral-only indication in CABP. We believe these initiatives have the potential to treat patients in need and drive additional long-term value for all shareholders. We look forward to keeping you apprised of our progress on these promising opportunities.”

Recent Highlights

• Executed a royalty-backed loan agreement with Healthcare Royalty Partners III, L.P. (HCRP) to borrow $32.5 million to be funded May 1, 2019, which will be secured by and repaid from royalties received by Paratek from the net sales of SEYSARA in the United States by Almirall, LLC.
• New England Journal of Medicine (NEJM) published 2 manuscripts with detailed results from the Company’s Phase 3 clinical trials (OPTIC and OASIS-1) of NUZYRA™ (omadacycline) highlighting the potential clinical impact that NUZYRA can have on the practice of medicine in an era of growing resistance to older antibiotic agents.
• NUZYRA launched in the United States in February 2019 as a once-daily oral and intravenous antibiotic for the treatment of adults with community-acquired bacterial pneumonia (CABP) and acute skin and skin structure infections (ABSSSI).
  • In concert with the U.S. launch, three antimicrobial susceptibility tests are now available for use with NUZYRA. Paratek has also launched the KEYSTONETM surveillance program to monitor omadacycline susceptibility. 
• The Company’s partner, Almirall, launched SEYSARATM in the U.S., in January 2019. SEYSARA is a once-daily, oral, narrow spectrum tetracycline-derived antibiotic with anti-inflammatory properties for the treatment of moderate to severe acne in the community setting. Paratek is entitled to receive tiered royalties at rates ranging from high single to low double digits of net U.S. sales of SEYSARA and retains all ex-U.S. rights.
• Filed two patent term extensions for NUZYRA in the United States; the Company now expects patent protection until at least October 2030, two years beyond the ten years of exclusivity provided by the Hatch-Waxman and GAIN Acts.
• Dosed the first patient in a Phase 2 study evaluating the potential efficacy and safety of oral and intravenous (IV) omadacycline for the treatment of acute pyelonephritis, a common subset of complicated urinary tract infections (cUTI).
• The European Marketing Authorization Application for oral and IV omadacycline was submitted in October 2018 and the review has been initiated.
  • The Company is seeking approval for the treatment of CABP and ABSSSI.

Fourth Quarter and Full Year 2018 Financial Results
For the fourth quarter of 2018, Paratek reported a net loss of $22.8 million, or ($0.71) per share, compared to a net loss of $21.9 million, or ($0.78) per share, for the same period in 2017. For the year ended December 31, 2018, Paratek reported a net loss of $112.4 million, or ($3.57) per share, compared to a net loss of $89.1 million, or ($3.32) per share, for the same period in 2017.

Revenue earned during the year ended December 31, 2018 of $17.1 million was $4.5 million higher than revenue earned during the same period in prior year. Revenue earned during the year ended December 31, 2018 was primarily attributable to a $12.0 million milestone earned from Almirall, LLC upon FDA approval of SEYSARA and a $5.0 million milestone earned from Zai Lab upon FDA approval of NUZYRA. Revenue earned during the year ended December 31, 2017 of $12.6 million was primarily attributable to a $7.5 million upfront payment received as part of an omadacycline collaboration agreement with Zai Lab and a $5.0 million milestone payment earned from Allergan plc on FDA acceptance of the SEYSARA NDA.

Research and development expenses were $11.8 million and $57.5 million for the quarter and year ended December 31, 2018, respectively, compared to $14.2 million and $60.1 million for the same periods in 2017. The slight decrease for both periods was driven primarily by lower clinical study costs, offset by higher compensation-related costs, including stock-based compensation expense, manufacturing production costs for omadacycline and costs associated with additional regulatory activities.

General and administrative expenses were $25.3 million and $63.7 million for the quarter and year ended December 31, 2018, respectively, compared to $11.7 million and $37.0 million for the same periods in 2017. The increase in general and administrative expenses for both periods was due to higher compensation-related costs associated with increased headcount and stock-based compensation expense as well as increased spend related to the U.S. launch of NUZYRA.

Based upon Paratek’s current operating plan, the Company anticipates that its existing cash, cash equivalents and marketable securities of $292.8 million as of December 31, 2018, estimated NUZYRA product sales, and SEYSARA royalty-backed loan with HCRP will fund company operating expenses, capital expenditures, and debt service beyond the first quarter of 2021.

Financial Guidance
Paratek also reiterated its 2019 NUZYRA U.S. net product revenue guidance, expected to be between $10.0 and $13.0 million. Paratek may experience events that could cause actual results to vary from this guidance. Paratek plans to provide one update to its annual financial guidance, which is expected to be provided in connection with its second quarter earnings release.
