BOSTON, Aug. 04, 2016 (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 June 30, 2016.

"Our clinical development program for omadacycline continues to progress well. We have successfully completed our Phase 3 registration study in Acute Bacterial Skin and Skin Structure  infections (ABSSSI), and our Phase 3 study in community acquired bacterial pneumonia (CABP) continues to progress according to plan. With our progress to date, we remain on track to file a new drug application for omadacycline in the United States in the first half of 2018,” said Michael Bigham, Chairman and Chief Executive Officer, Paratek. “In parallel, we are continuing to expand the potential clinical applications of  omadacycline. Enrollment in our Phase 1b study with omadacycline for the treatment of urinary tract infections (UTI) is nearly complete, with top-line data expected in Q4; and we expect to initiate enrollment this month in our Phase 3 study with omadacycline for the oral-only treatment of ABSSSI.”

Recent Paratek Highlights

• Announced successful achievement of the primary and secondary efficacy endpoints comparing omadacycline to linezolid in the treatment of ABSSSI. Omadacycline met both the U.S. Food and Drug Administration (FDA)-specified primary efficacy endpoint of early clinical response as well as the European Medicines Agency (EMA)-specified co-primary efficacy endpoint for post-treatment evaluation.
• Phase 3 registration study evaluating omadacycline for the treatment of CABP remains on track to report top-line data as early as the third quarter of 2017.

Upcoming Milestones

• Dosing of first patient in oral-only Phase 3 study evaluating omadacycline for the treatment of ABSSSI expected in August 2016.
• Announcement of top-line data from Phase 1b study evaluating omadacycline for the treatment of UTI expected in the fourth quarter of 2016. Enrollment in this study is nearly complete.

Financial Results
For the quarter ended June 30, 2016, Paratek reported a net loss of $30.3 million, or $1.69 per share, compared to a net loss of $15.7 million, or $0.96 per share, for the same period in 2015.

Research and development expenses were $22.1 million for the three months ended June 30, 2016, compared to $11.0 million for the same period in 2015. The increase in research and development expense during the three months ended June 30, 2016 was primarily the result of the Company’s ongoing clinical development of omadacycline, notably from its Phase 3 studies for the treatment of CABP and ABSSSI, a Phase 1b study for the treatment of UTI, and other Phase 1 studies required for submission of the planned New Drug Application.

During the current quarter, the Company incurred approximately $11.4 million in expense associated with its Phase 3 studies for the treatment of ABSSSI and CABP, including a Phase 3 oral-only study, which represents an increase of $4.5 million compared to $6.9 million in the same period in the prior year. This increase is associated primarily with strong enrollment in the CABP registration study, resulting in an increased recognition of expenses related to contract research organization fees, investigator fees, and costs associated with clinical sites and laboratories, as well as study start-up costs for a planned Phase 3 oral-only study in ABSSSI. The Company also incurred $2.3 million in production costs for omadacycline registration batches and manufacturing process validation work, which represents an increase of $0.9 million compared to the same period in prior year.

Also during the quarter, the Company incurred $5.9 million in costs from omadacycline Phase 1 studies and other research and development activities and $2.5 million in salaries and benefits, including stock-based compensation, which represents an increase of $4.6 million and $1.1 million, respectively, compared to the same period in prior year, due to the conduct of additional Phase 1 studies and increased headcount.

The increase in general and administrative costs for the three months ended June 30, 2016 was primarily due to growth in the Company’s corporate infrastructure. Salaries and benefits, including stock-based compensation, increased $1.9 million, and professional and consulting services, including legal, accounting, and audit fees, increased $1.1 million for the three months ended June 30, 2016 compared to the same period in prior year.

As of June 30, 2016, Paratek had cash, cash equivalents, and marketable securities of $150.4 million. Based on current assumptions, Paratek’s cash, cash equivalents and marketable securities, as well as the $20.0 million available to us under the Loan Agreement with Hercules, will enable the Company to fund operating expenses and capital expenditure requirements through the submission of a new drug application for omadacycline for the treatment of ABSSSI and CABP, which the Company currently expects to occur in the first half of 2018.

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 data in a Phase 3 registration study in ABSSSI demonstrating the efficacy, safety and tolerability of the once-daily oral and IV formulations of omadacycline compared to linezolid. A Phase 3 registration study for community acquired bacterial pneumonia (CABP) comparing omadacycline to moxifloxacin was initiated in November 2015 and top line data is expected as early as the third quarter of 2017. A phase 1b study in uncomplicated urinary tract infections (uUTI) was initiated in May 2016. Omadacycline has been granted QIDP and Fast Track status by the U.S. Food and Drug Administration.

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.
