“We had a strong finish to the year as we initiated our Phase 2 program in urinary tract infections and, importantly, we recently announced the completion of the rolling NDA submissions for omadacycline,” said Michael Bigham, Chairman and Chief Executive Officer, Paratek. “We continue to expand our commercial readiness activities for omadacycline as we await the FDA’s acceptance of our NDAs.”

• Advanced commercial readiness activities, including initiation of manufacturing validation and commercial product supply and expansion of the medical affairs and payer account management teams in readiness for payer formulary discussions
• Initiated the first of two Phase 2 studies of omadacycline in urinary tract infections (UTI)
• Announced FDA acceptance of Allergan’s NDA for Seysara
• Raised $50.0 million through a registered underwritten public offering of common stock

Upcoming Milestones

• Formulary discussions with payers to begin post FDA acceptance of NDA filing
• Presentation of clinical and microbiological data at the upcoming European Congress of Clinical Microbiology and Infectious Disease, including nine posters and one oral presentation of the OASIS-2 study of oral-only omadacycline in ABSSSI

Fourth Quarter and Full Year 2017 Financial Results
For the fourth quarter of 2017, Paratek reported a net loss of $21.9 million, or ($0.78) per share, compared to a net loss of $26.5 million, or ($1.16) per share, for the same period in 2016.  For the year ended December 31, 2017, Paratek reported a net loss of $89.1 million, or ($3.32) per share, compared to a net loss of $111.6 million, or ($5.51) per share, for the same period in 2016.

Revenue earned during the year ended December 31, 2017 primarily consists of a $7.5 million upfront payment received as part of a collaboration agreement with Zai Lab and a $5.0 million milestone payment earned from Allergan on FDA acceptance of the Seysara NDA.

Research and development expenses were $14.2 million and $60.1 million for the quarter and year ended December 31, 2017, respectively, compared to $19.7 million and $83.5 million for the same periods in 2016. The decrease was driven primarily by lower clinical study costs associated with the completion of the Phase 3 program for omadacycline.  This decrease is partially offset by higher employee compensation costs, NDA preparation and related user fees, and an increase in medical affairs activity.

General and administrative expenses were $11.7 million and $37.0 million for the quarter and year ended December 31, 2017, respectively, compared to $6.5 million and $26.4 million for the same periods in 2016.  The increase was driven primarily by higher employee compensation costs as the Company continues to expand its commercial team, costs associated with pre-commercial activities, and business development efforts.

As of December 31, 2017, Paratek had cash, cash equivalents, and marketable securities of $151.7 million. Based on current assumptions, including full commercial buildout and launch of omadacycline, Paratek’s existing capital resources as well as the $50 million in proceeds from its January 2018 public offering of common stock, future contingent regulatory and commercial milestone payments from collaborations with Allergan and Zai Lab, anticipated extension of the interest-only period for the Hercules Term Loan, and estimated omadacycline product sales will enable Paratek to fund operating expenses and capital expenditure requirements into late 2019.
