BOSTON, May 08, 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 ended March 31, 2019.

“We are pleased with the results from the first eight weeks of the NUZYRA launch in the United States. We have achieved several of our early benchmarks that we believe are necessary to create a strong foundation for long-term commercial success,” said Michael Bigham, Chairman and Chief Executive Officer, Paratek. “The organization is motivated and focused on the launch of NUZYRA. We appreciate that it takes sustained effort and patience to establish momentum for any new antibiotic in the hospital setting. To date, our efforts have been focused on establishing a robust supply chain and distribution channel, actively educating and building awareness with the key stakeholders on the potential benefits NUZYRA offers and ensuring patients have access to this potential life-saving therapy.”

“With the U.S. launch of NUZYRA successfully underway, we continue to pursue a number of compelling life-cycle opportunities for NUZYRA. These include executing two phase 2 studies in UTI, for which we expect topline data in the second half of 2019 and exploring the potential avenues to achieve an oral-only indication in CABP,” said Evan Loh, M.D., President, Chief Operating Officer and Chief Medical Officer. “We believe these potential value drivers provide opportunity to both accelerate commercial success as well as significantly expand the accessible market. We look forward to keeping you apprised of our progress on these promising opportunities in the months ahead.”

First Quarter 2019 NUZYRA Commercial Highlights

• After an early February launch, NUZYRA generated $1.3 million in net revenues in the U.S. in its first approximately eight weeks on the market.
  • The Company estimates approximately 85% of NUZYRA revenues were related to the initial inventory build of the oral formulation in the channel.

• Approximately 1/3 of commercial lives in U.S. had access to NUZYRA by the end of the first quarter 2019.
• Aided awareness with target prescribers conducted through market research increased from 27% to 48% since launch.
• Institutional access achieved in over 50% of approximately 400 targeted institutions.

Other Recent Highlights

• Data from the NUZYRA clinical and microbiology programs were presented at the 29^thEuropean Congress of Clinical Microbiology & Infectious Diseases, ECCMID 2019. Nine presentations at the congress continued to highlight the efficacy and safety profile of NUZYRA, adding to the growing body of evidence of the therapy’s utility against relevant pathogens and life-threatening infections such as CABP and ABSSSI.
• Scientific team who worked on the chemistry and clinical development programs for NUZYRA and SEYSARA™ were awarded the American Chemical Society’s (ACS) 2019 Heroes of Chemistry Award.  
• New England Journal of Medicine (NEJM) published two 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 KEYSTONE™ surveillance program to monitor omadacycline susceptibility. 

• Company received gross proceeds of $32.5 million on May 1, 2019 related to recently executed royalty-backed loan agreement with Healthcare Royalty Partners III, L.P. (HCRP). This royalty-backed loan agreement will be secured by and repaid from royalties received by Paratek from the net sales of SEYSARA in the United States by Almirall, LLC.
• The Company’s partner, Almirall, launched SEYSARA in the U.S., in January 2019.  

First Quarter 2019 Financial Results
For the first quarter of 2019, Paratek reported a net loss of $35.6 million, or ($1.10) per share, compared to a net loss of $27.8 million, or ($0.91) per share, for the same period in 2018. 

Revenue earned during the quarter ended March 31, 2019 was attributable to net U.S. NUZYRA product revenue of $1.3 million and royalty revenue of $0.3 million, which included royalties earned from SEYSARA sales in the U.S.

Research and development expenses were $11.4 million for the quarter ended March 31, 2019 compared to $14.9 million for the same period in 2018. This decrease is primarily the result of the capitalization of NUZYRA commercial supply costs, which were classified as research and development expense until FDA approval of NUZYRA on October 2, 2018, and lower NDA user fees due to timing of our NDA submissions, partially offset by higher clinical study costs associated with our Phase 2 UTI program.  

Selling, general and administrative expenses were $23.3 million for the quarter ended March 31, 2019, compared to $11.9 million for the same period in 2018. The increase is primarily the result of the cost of our contract sales force, higher marketing, trade and distribution fees, and increased salaries, benefits and other personnel-related costs in support of the commercialization of NUZYRA.

Based upon Paratek’s current operating plan, the Company anticipates that its existing cash, cash equivalents and marketable securities of $257.9 million as of March 31, 2019, estimated NUZYRA product sales, and SEYSARA royalty-backed loan with HCRP gross proceeds of $32.5 million, which was funded on May 1, 2019, will fund company operating expenses, capital expenditures, and debt service beyond the first quarter of 2021.
