Fourth Quarter and Full Year 2016 Financial Results
For the fourth quarter of 2016, Paratek reported a net loss of $26.5 million, or $1.16 per share, compared to a net loss of $21.1 million, or $1.20 per share, for the same period in 2015.  For the year ended December 31, 2016, Paratek reported a net loss of $111.6 million, or $5.51 per share, compared to a net loss of $70.9 million, or $4.29 per share, for the same period in 2015.

Research and development expenses were $19.7 million and $83.5 million for the quarter and year ended December 31, 2016, respectively, compared to $15.2 million and $50.8 million for the same periods in 2015. The increase in research and development expense for the year ended December 31, 2016 was primarily the result of ongoing development of omadacycline, including costs associated with clinical studies for the treatment of ABSSSI, CABP and UTI, production of omadacycline registration batches and manufacturing process validation work, other research and development activities, and employee compensation.

General and administrative expenses were $6.5 million and $26.4 million for the quarter and year ended December 31, 2016, respectively, compared to $5.6 million and $20.0 million for the same periods in 2015.  The increase in general and administrative costs was primarily the result of employee compensation.

As of December 31, 2016, Paratek had cash, cash equivalents, and marketable securities of $128.0 million. Based on current assumptions, Paratek’s cash, cash equivalents and marketable securities will enable the Company to fund operating expenses and capital expenditure requirements through the first half of 2018.

Paratek initiated sales of shares under a Controlled Equity Offering Sales Agreement with Cantor Fitzgerald & Co. in March 2016, and sold an aggregate of 860,014 shares of common stock through December 31, 2016, resulting in net proceeds of $11.6 million.  As of February 24, 2017, an additional 870,078 shares were sold under the Sales Agreement subsequent to December 31, 2016, resulting in net proceeds of $13.1 million, which will be recognized during the first quarter of 2017.

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, is the first in a new class of tetracyclines known as aminomethylcyclines, with broad-spectrum activity against Gram-positive, Gram-negative and atypical bacteria. 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 safety of intravenous (IV) to once-daily oral omadacycline compared to linezolid.  A Phase 3 registration study for community-acquired bacterial pneumonia (CABP) comparing IV-to-once-daily oral omadacycline to IV-to-oral moxifloxacin was initiated in November 2015 and completed enrollment in January 2017. Paratek will report top-line data from this study early in the second quarter of 2017. 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.  Top-line data from this study are expected as early as the second quarter of 2017.  A Phase 1B study in uncomplicated urinary tract infections (UTI) was initiated in May 2016 and positive top-line PK proof-of-principle data were reported in November 2016.  The company plans to begin enrolling patients in a proof-of-concept Phase 2 study in complicated UTI as early as the fourth quarter of 2017. Omadacycline has been granted Qualified Infectious Disease Product designation and Fast Track status by the U.S. Food and Drug Administration for several indications.

In October 2016, Paratek announced a new cooperative research effort with the U.S. Army Medical Research Institute of Infectious Diseases (USAMRIID) to study omadacycline against pathogenic agents causing infectious diseases of public health and biodefense importance. These studies are designed to confirm dosing regimens and assess efficacy of omadacycline against biodefense pathogens, including Yersinia pestis (plague) and Bacillus anthracis (anthrax).

Omadacycline is a new once-daily oral and IV, well-tolerated 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.

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 initiated two identical Phase 3 registration studies in December 2014 for sarecycline for the treatment of moderate to severe acne vulgaris. Top-line Phase 3 data are expected in the first half of 2017.
