Description of the business Description of the business
Paratek Pharmaceuticals, Inc., or the Company or Paratek, is a Delaware corporation with its corporate office in Boston, Massachusetts and an office in King of Prussia, Pennsylvania.
The Company is 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. The Company’s United States, or U.S., Food and Drug Administration, or FDA, approved commercial product, NUZYRA® (omadacycline), is a once-daily oral and intravenous antibiotic for the treatment of adult patients with community-acquired bacterial pneumonia, or CABP, and acute skin and skin structure infections, or ABSSSI, caused by susceptible pathogens. The Company retains worldwide commercial rights to omadacycline, with the exception of the People’s Republic of China, Hong Kong, Macau and Taiwan, where it has entered into a collaboration agreement with Zai Lab (Shanghai) Co., Ltd., or Zai. The National Medical Products Administration, or NMPA, of China approved NUZYRA for the treatment of CABP and ABSSSI in December 2021.
SEYSARA® (sarecycline) is an FDA-approved product with respect to which the Company has exclusively licensed in the U.S. and the People’s Republic of China, or the PRC, Hong Kong and Macau, or the greater China region, certain rights to Almirall, LLC, or Almirall. SEYSARA is currently being marketed by Almirall in the U.S. as a once-daily oral therapy for the treatment of moderate to severe acne vulgaris. With respect to the Company’s technology as it relates to sarecycline, the Company retains development and commercialization rights in all countries other than the U.S. and the greater China region, and in February 2020, the Company exclusively licensed from Almirall certain technology owned or in-licensed by Almirall or its affiliates that is necessary or useful to develop or commercialize sarecycline outside of the U.S. Almirall plans to develop sarecycline for acne in China, with a submission to the NMPA, according to Almirall, expected in 2023.
The Company has incurred significant losses since inception in 1996. The Company has generated an accumulated deficit of $884.8 million through March 31, 2022 and may require substantial additional funding in connection with the Company’s continuing operations to support clinical development and commercialization activities associated with NUZYRA. Based upon the Company’s current operating plan, it anticipates that its cash, cash equivalents and marketable securities of $79.1 million as of March 31, 2022 will enable the Company to fund operating expenses and capital expenditure requirements through at least the next twelve months from the issuance of the financial statements included in this Quarterly Report on Form 10-Q. The Company expects to finance future cash needs primarily through a combination of product sales, royalties, public or private equity offerings, debt or other structured financings, strategic collaborations, grant funding and government funding. The Company is subject to risks common to companies in the biopharmaceutical industry, including, but not limited to, risks of failure of preclinical studies and clinical trials, the need to obtain additional financing to fund the future development of the Company’s product candidates, the need to obtain compliant product from third-party manufacturers, the need to obtain marketing approval for the Company’s product candidates, the need to successfully commercialize and gain market acceptance of product candidates, the risks of manufacturing product with an external supply chain, dependence on key personnel, and compliance with government regulations as well as the risks discussed in the “Risk Factors” section of the Company’s Annual Report on Form 10-K for the year ended December 31, 2021, as filed with the U.S. Securities and Exchange Commission, or the SEC, on March 14, 2022, or the 2021 Form 10-K, and in the Company’s other filings with the SEC.
