— NUZYRA® (omadacycline) Generated Net U.S. Sales of $14.9 Million from the Core Commercial Business, a 13% Increase over the Prior Quarter — Reported $37.9 Million in Revenue from the Delivery of the First BARDA Procurement of NUZYRA — Received FDA Approval of NUZYRA Oral Only Loading-Dose Regimen for the Treatment of Community-Acquired Bacterial Pneumonia (CABP) — Initiated Phase 2b Study in Non-Tuberculous Mycobacterium Abscessus BOSTON, Aug. 09, 2021 (GLOBE NEWSWIRE) — Paratek Pharmaceuticals, Inc. (Nasdaq: PRTK), a commercial-stage biopharmaceutical company focused on the development and commercialization of novel life-saving therapies for life-threatening diseases or other public health threats for civilian, government and military use, today reported financial results and provided an update on corporate activities for the quarter ended June 30, 2021. “We continued to deliver consistent growth and progress in the second quarter with the core NUZYRA commercial business seeing quarter over quarter growth, as net sales increased 13% to $14.9 million versus the first quarter,” said Evan Loh, M.D., Chief Executive Officer at Paratek. “We were also excited to announce that the first BARDA procurement valued at $37.9 million was delivered and accepted in the second quarter as we continued to execute on all aspects of this unique contract with BARDA. NUZYRA’s label was expanded in the second quarter with the FDA approval of the oral loading dose regimen for community-acquired bacterial pneumonia. Importantly, we continued to advance our pipeline for NUZYRA with the initiation of a Phase 2b non-tuberculous mycobacteria (NTM) abscessus study, a rare disease for which there are no approved therapies.” Highlights Oral loading dose regimen for CABP: Received FDA approval for NUZYRA’s oral loading dose regimen for CABP in late May 2021. Plans have been established to broaden the Company’s community-based sales effort in the primary care setting to include CABP later this year in anticipation of the 2021/2022 flu season. The Company estimates that CABP in the primary care setting has a $1.5 billion addressable market opportunity in the U.S.NTM abscessus rare disease opportunity: Initiated a Phase 2b study in June 2021 to explore the potential utility of omadacycline as a treatment for NTM abscessus pulmonary infection, a rare disease with no approved therapies, which the Company estimates is a $1.0 billion addressable market opportunity in the U.S.Continued progress of the BARDA Project BioShield anthrax program: Biomedical Advanced Research and Development Authority (BARDA) accepted the first procurement of NUZYRA valued at $37.9 million. The Company continues to execute and deliver on its five-year contract with BARDA, part of the Office of the Assistant Secretary for Preparedness and Response (ASPR) at the U.S. Department of Health and Human Services (HHS), to develop NUZYRA for the treatment of pulmonary anthrax, a critical bioterrorism threat deemed important to national security by BARDA. These activities include advancing the U.S. onshoring of NUZYRA manufacturing and the continued execution of certain preclinical research activities supporting the pulmonary anthrax development program.NUZYRA added to the Center for Disease Control and Prevention’s (CDC) Plague Guideline: The Company’s novel, once-daily oral and intravenous antibiotic NUZYRA has recently been added to the CDC’s updated guideline, Antimicrobial Treatment and Prophylaxis of Plague: Recommendations for Naturally Acquired Infections and Bioterrorism Response. The addition of NUZYRA provides further validation of the potential utility of the drug against pathogens that cause health security threats such as plague.Nuzyra included in CHEST, “Treatment of Mycobacterium abscessus Pulmonary Disease”: Two recognized NTM experts, who are NTM treatment guideline authors, collaborated on a recently published review article that expands on the current guidelines for the treatment of pulmonary M. abscessus infections. The authors included omadacycline in their recommended treatment options based on its potent in vitro activity and reports of clinical success in real-world NTM abscessus case series. In particular, the authors highlighted the importance of NUZYRA’s oral formulation given the lack of currently available oral treatment options. Second Quarter 2021 Financial Results Total revenue was $57.5 million for the second quarter of 2021. NUZYRA generated $52.8 million in net U.S. sales during the second quarter of 2021. This revenue includes $14.9 million from the core commercial business, a 13% increase over the first quarter of 2021 and an 84% increase over the second quarter of 2020, and $37.9 million from the first BARDA procurement.Government contract service and grant revenue earned from costs incurred under the BARDA contract was $4.2 million for the second quarter of 2021 versus $2.6 million in the first quarter of 2021 and $0.9 million in the second quarter of 2020. Research and development (R&D) expenses were $6.5 million for the second quarter of 2021, compared to $4.6 million for same period in the prior year. The increase in R&D expenses for the second quarter of 2021 was primarily due to $4.2 million in costs reimbursed under the BARDA contract, which included costs for the U.S. onshoring of NUZYRA manufacturing and for FDA post-marketing requirements, or PMRs, associated with the approval of NUZYRA. The remaining increase is mainly the result of start-up costs incurred for the Phase 2b NTM study. Selling, general and administrative (SG&A) expenses were $27.1 million for the second quarter of 2021, compared to $21.0 million for the same period in the prior year. The increase in SG&A expenses is primarily the result of costs incurred for the NUZYRA community expansion and an increase in stock-based compensation expense due to the probability and timing of the achievement of performance-based vesting milestones. Paratek reported net income of $9.7 million, or $0.20 per share, for the second quarter of 2021, compared to a net loss of $23.1 million, or ($0.53) per share, for the same period in 2020. Financial Guidance  Paratek is maintaining its previously disclosed financial guidance, which moved approximately $38 million associated with the second procurement of NUZYRA by BARDA from its 2021 revenue expectations.Based upon the Company’s current operating plan, Paratek anticipates its existing cash and cash equivalents of $75.3 million as of June 30, 2021, plus the $37.9 million received from BARDA in July 2021 for the first procurement of NUZYRA, provides for a cash runway through the end of 2023 with a pathway to cash flow break even. Company performance and unanticipated events could cause actual results to vary from this forward-looking guidance.  Call and WebcastParatek’s earnings conference call for the quarter ended June 30, 2021 will be broadcast at 4:30 p.m. EDT on August 9, 2021.
