BOSTON, Nov. 08, 2021 (GLOBE NEWSWIRE) -- Paratek Pharmaceuticals, Inc. (NASDAQ:PRTK), today reported financial results and provided an update on corporate activities for the quarter ended September 30, 2021.

"We are extremely proud of the 30% quarter-over-quarter growth in the core NUZYRA commercial business despite continued challenges from the ongoing COVID-19 pandemic. Our performance this quarter reflects continued strong execution and momentum," said Evan Loh, M.D., chief executive officer at Paratek. "Other highlights during this quarter included broadening our promotion of NUZYRA for the treatment of pneumonia in the community setting. In addition, the BARDA contract has now been expanded to include a NUZYRA sNDA program for prophylaxis as well as treatment of anthrax. And finally, we enrolled the first patient in our Phase 2b study evaluating the utility of NUZYRA as a treatment for NTM abscessus. This follows the orphan drug designation for NTM granted by the FDA in August."

Highlights:

Both Hospital and Community Prescribers Fueled Growth of NUZYRA: Tablet prescriptions continued to increase in both the outpatient and hospital settings, leading to significant growth in demand for the third quarter of 2021.
BARDA Expanded Paratek Contract: Biomedical Advanced Research and Development Authority (BARDA), part of the Office of the Assistant Secretary for Preparedness and Response at the U.S. Department of Health and Human Services, activated an option under the Company's Project BioShield contract that provides $31.6 million in committed funding, of which $18.9 million was incremental to the original development program. This funding will fully support the development of NUZYRA^® for a supplemental new drug application (sNDA) to the FDA for the post-exposure prophylaxis indication in addition to the development program for the treatment of pulmonary anthrax.
Orphan Drug Designation for NUZYRA Granted by the FDA for the Treatment of NTM in August 2021
First Patient Enrolled in NTM abscessus study: First patient enrolled in October in the company's Phase 2b study evaluating the efficacy and safety of NUZYRA as a treatment for NTM abscessus pulmonary infection, a rare disease with no FDA-approved therapies. The company estimates NTM abscessus is a $1.0 billion addressable market opportunity in the United States.
NUZYRA Data at IDWeek 2021: Peer-reviewed data deepened the understanding of the utility of NUZYRA for serious community-acquired infections and NTM as well as its potential in treating anthrax infections. Key highlights include real-world health outcomes data for pneumonia and skin infections, data on in vitro activity against B. anthracis, and real-world experience for NTM infections.

Third Quarter 2021 Financial Results

Total revenue was $24.4 million for the third quarter of 2021.

NUZYRA generated $19.4 million in net U.S. sales from the core commercial business during the third quarter of 2021, a 30% increase over the second quarter of 2021 and a 78% increase over the third quarter of 2020.
Government contract service and grant revenue earned from cost reimbursement under the BARDA contract was $4.5 million for the third quarter of 2021 compared to $4.2 million in the second quarter of 2021 and $2.7 million in the third quarter of 2020.

Research and development (R&D) expenses were $7.9 million for the third quarter of 2021, of which $4.5 million were costs reimbursed under the BARDA contract, compared to $6.7 million for same period in the prior year. The increase in R&D expenses for the third quarter of 2021 was primarily due to FDA post-marketing requirements associated with the approval of NUZYRA, which are fully reimbursed under the BARDA contract. The remaining increase was mainly the result of costs incurred for the Phase 2b NTM study.

Selling, general and administrative (SG&A) expenses were $26.0 million for the third quarter of 2021, compared to $20.9 million for the same period in the prior year. The increase in SG&A expenses was primarily the result of costs incurred for the NUZYRA community expansion.

Paratek reported a net loss of $18.2 million, or ($0.37) per share, for the third quarter of 2021, compared to a net loss of $20.9 million, or ($0.46) per share, for the same period in the prior year.

Financial Guidance

Paratek anticipates net revenue of NUZYRA will be at the higher end of the previously indicated range of $100 to $106 million, which includes the $38 million NUZYRA procurement by BARDA in June 2021. Total Revenue is expected to be within the previously indicated range of $128 to $139 million. Total R&D and SG&A expenses are projected to be within the original guidance range of $150 to $155 million.
Based upon the company's current operating plan, Paratek anticipates its existing cash and cash equivalents of $111.0 million as of September 30, 2021, provides for a cash runway through the end of 2023 with a pathway to cash flow break even.
