-- NUZYRA® (omadacycline) Generated Net U.S. Sales of $25.5 Million from the Core Commercial Business, a 31% increase from $19.4 Million in Third Quarter 2021

-- Initiated Rabbit Pilot Efficacy Study for the Treatment of Pulmonary Anthrax

-- Announced Commercial Availability of U.S.-manufactured NUZYRA Tablets

BOSTON, Nov. 03, 2022 (GLOBE NEWSWIRE) -- Paratek Pharmaceuticals, Inc. (NASDAQ:PRTK), today reported financial results and provided an update on corporate activities for the quarter ended September 30, 2022.

"We are pleased to report another strong quarter of growth in NUZYRA's core commercial business, as evidenced by the 31% increase in net U.S. sales compared to the same period in 2021. NUZYRA's core commercial business achieved a 52% increase in trailing 12-month net U.S. sales as a result of accelerating product demand and the disciplined execution of our community sales force expansion," said Evan Loh, M.D., chief executive officer at Paratek. "Based on our results to date, we continue to reiterate our full-year 2022 financial guidance."

Recent Highlights

Completed Second Wave of Expansion in Primary Care: This wave of the company's commercial and medical expansion into the community setting was completed during the third quarter of 2022. These efforts included an increase in the number of sales representatives, medical science liaisons, and territories covered in the primary care setting. Early leading indicators of the performance of the new community sales cohort are promising, including prescription data aligning with the initial wave of community expansion completed in the first quarter of 2021.
Hosted an Investor Day on the Global Opportunity for NUZYRA in Non-Tuberculous Mycobacteria (NTM): The company hosted an Investor Day event on October 3 to update investors on the global market opportunity for NTM in both M. abscessus and M. avium complex (MAC). This event highlighted the significant global unmet medical need for patients suffering from this chronic, rare and life-threatening pulmonary disease and the potential clinical utility of NUZYRA based on data generated to date. These data and efforts further support ex-U.S. partnering discussions for the treatment of NTM in key global markets. A replay of the event can be accessed via the following link: NTM Investor Day Webcast Replay.
Continued Progress of the BARDA Project BioShield Program: The company has continued to execute on its contractual deliverables on the BARDA contract. The Animal Rule program for both the treatment and post-exposure prophylaxis of pulmonary anthrax continues to progress with the initiation of the rabbit pilot efficacy study for the treatment indication. We anticipate that positive top line data from this study will trigger BARDA's second procurement of 2,500 NUZYRA anthrax treatment courses. In addition, the onshoring program continues to progress with tablet validation and manufacturing now complete. As a result, U.S.-manufactured NUZYRA tablets are now commercially available.
Scientific Congresses: The company has recently participated in several important in-person scientific congresses, including the Military Health System Research Symposium (MHSRS), the Academy of Managed Care Pharmacy (AMCP) Nexus, the American College of Chest Physicians (CHEST), and IDWeek. Peer-reviewed data presented at these conferences furthers the understanding of NUZYRA's utility for serious community-acquired and combat-associated infections.

Financial Results

Total revenue for the third quarter of 2022 was $30.2 million, a 24% increase from $24.4 million for the same period in the prior year. Revenue earned in the third quarter of 2022 was comprised of $25.5 million in net U.S. sales from the NUZYRA core commercial business, a 31% increase from $19.4 million for the same period in the prior year; $4.4 million in revenue earned under the BARDA contract; and $0.3 million in royalty revenue.

Research and development (R&D) expenses were $8.5 million for the third quarter of 2022, compared to $7.9 million for the same period in the prior year. The increase in R&D expenses was primarily the result of costs incurred under our BARDA contract, including the timing of activities for the U.S. onshoring of NUZYRA manufacturing and additional work completed under the anthrax development program, partially offset by lower clinical study costs associated with our post-marketing required clinical study for adult patients with community-acquired bacterial pneumonia (CABP).

Selling, general and administrative (SG&A) expenses were $33.8 million for the third quarter of 2022, compared to $26.0 million for the same period in the prior year. The increase in SG&A expenses was primarily the result of compensation expense and costs incurred for the expansion of NUZYRA promotion into the primary care setting.

Paratek reported a net loss of $20.9 million, or ($0.38) per share, and $18.2 million, or ($0.37) per share, for the third quarters of 2022 and 2021, respectively.

Based upon the company's current operating plan, Paratek anticipates its existing cash, cash equivalents and marketable securities of $57.0 million as of September 30, 2022, provides for a cash runway through the end of 2023 with a pathway to cash flow break-even.
