BOSTON, May 04, 2017 (GLOBE NEWSWIRE) --  Paratek Pharmaceuticals, Inc. (Nasdaq:PRTK), a biopharmaceutical company focused on the development and commercialization of innovative therapies based upon tetracycline chemistry, today reported financial results for the quarter ended March 31, 2017.

"The announcement of positive top-line data in April from our successful Phase 3 registration study in pneumonia was a critically important milestone in the development of omadacycline,” said Michael Bigham, Chairman and Chief Executive Officer, Paratek. “Together, this study and our previously announced successful Phase 3 study in skin infections satisfy the regulatory filing requirements of our special protocol assessments with the FDA. Our plan is to submit for regulatory approval in the U.S. as early as the first quarter of 2018 with an EMA submission later in 2018. In addition, we recently announced a collaboration with Zai Lab to develop, manufacture and commercialize omadacycline for the greater China region. We also recently made thirteen presentations on omadacycline, including two oral sessions, at the European Congress of Clinical Microbiology and Infectious Diseases (ECCMID).”

Recent Highlights

• Reported positive top-line efficacy and safety data in the OPTIC study, a Phase 3 registration study of omadacycline in CABP
• Enrollment nearly completed in the OASIS-2 study, a Phase 3 registration study of oral-only omadacycline in acute bacterial skin and skin structure infections (ABSSSI) with top-line data now expected by mid-July
• Narrowed the projected window to submit the New Drug Applications for the oral and IV formulations with the U.S. Food and Drug Administration from as early as the first half 2018 to as early as the first quarter 2018
• Presented 11 posters and 2 oral sessions at ECCMID in Vienna, Austria
• Signed a license and collaboration agreement with Zai Lab for omadacycline in the People’s Republic of China, Hong Kong, Macau, and Taiwan

Financial Results

Paratek reported a net loss of $27.7 million, or $1.14 per share, for the quarter ended March 31, 2017 compared to a net loss of $31.3 million, or $1.78 per share, for the same period in 2016. 

Research and development expenses were $18.7 million for the quarter ended March 31, 2017 compared to $24.3 million for the same period in 2016. The decrease was primarily driven by lower clinical study costs and reduced manufacturing production costs for omadacycline.

General and administrative expenses were $8.4 million for the quarter ended March 31, 2017 compared to $6.3 million for the same period in 2016.  The increase was primarily driven by an increase in consulting and legal fees, employee compensation costs, and other administrative expenses.

As of March 31, 2017, Paratek had cash, cash equivalents, and marketable securities of $139.6 million. Based upon Paratek’s current operating plan, the Company anticipates that its existing cash, cash equivalents and marketable securities, the remaining $10.0 million it may borrow under existing debt arrangements, proceeds to be received under its existing controlled equity offering agreements, and anticipated upfront and regulatory milestone payments from its collaborations with Allergan and Zai will enable the Company to fund its operating expenses and capital expenditure requirements into the second quarter of 2019.

About Paratek Pharmaceuticals, Inc.

Paratek Pharmaceuticals, Inc. is a biopharmaceutical company focused on the development and commercialization of innovative therapies based upon its expertise in novel tetracycline chemistry. Paratek's lead product candidate, omadacycline, when approved, will be the first in a new class of tetracyclines known as aminomethylcyclines, with broad-spectrum activity against Gram-positive, Gram-negative and atypical bacteria. Omadacycline is a new, once-daily oral and intravenous broad spectrum antibiotic being developed for use as empiric monotherapy for patients suffering from serious community-acquired bacterial infections, such as acute bacterial skin and skin structure infections, community-acquired bacterial pneumonia, urinary tract infections, and other community-acquired bacterial infections, particularly when antibiotic resistance is of concern to prescribing physicians. Omadacycline has been granted Qualified Infectious Disease Product designation and Fast Track status by the U.S. Food and Drug Administration for the target indications.

In June 2016, Paratek announced positive efficacy data in a Phase 3 registration study in acute bacterial skin and skin structure infections (ABSSSI) demonstrating the efficacy and general safety and tolerability of intravenous (IV) to once-daily oral omadacycline compared to linezolid. In April 2017, Paratek announced positive efficacy data in a Phase 3 registration study in community-acquired bacterial pneumonia (CABP) demonstrating the efficacy and general safety and tolerability of IV to once-daily oral omadacycline compared to moxifloxacin. A Phase 3 registration study in ABSSSI comparing once-daily oral-only dosing of omadacycline to twice-daily oral-only dosing of linezolid was initiated in August 2016. Enrollment of this study is nearly complete, with top-line data from this study expected by mid-July. The Company plans to submit its new drug application (NDA) in the U.S. as early as the first quarter of 2018 with an EMA submission later in 2018.

In addition to its Phase 3 program for omadacycline, a Phase 1B study in uncomplicated urinary tract infections (UTI) was initiated in May 2016 and positive top-line PK proof-of-principle data was reported in November 2016. The Company plans to begin enrolling patients in a proof-of-concept Phase 2 study of omadacycline in acute pyelonephritis, the most common subset of complicated urinary tract infections, as early as December 2017.

In October 2016, Paratek announced a research agreement with the U.S. Department of Defense to explore the utility of omadacycline against pathogenic agents causing infectious diseases of public health and biodefense importance including plague and anthrax.

In April 2017, Paratek Bermuda Ltd., a wholly-owned subsidiary of the Company, and Zai Lab (Shanghai) Co., Ltd., entered into a License and Collaboration Agreement. Under the terms of the Agreement, the Company granted Zai an exclusive license to develop, manufacture, and commercialize omadacycline in the People’s Republic of China, Hong Kong, Macau and Taiwan, for all human therapeutic and preventative uses, other than biodefense. Zai will be responsible for the development, manufacturing and commercialization of the licensed product in the licensed territory, at its sole cost with certain assistance from the Company.

Paratek's second Phase 3 product candidate, sarecycline, is a well-tolerated, once-daily oral, narrow spectrum tetracycline-derived antibiotic with potent anti-inflammatory properties for the potential treatment of acne and rosacea in the community setting. Allergan owns the U.S. rights for the development and commercialization of sarecycline. Paratek retains all ex-U.S. rights. Allergan and Paratek reported positive results from two identical Phase 3 registration studies of sarecycline for the treatment of moderate to severe acne vulgaris in March 2017. Allergan has publicly announced plans to submit an NDA in the U.S. in the second half of 2017.
