BOSTON, May 02, 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 March 31, 2016.

"Our clinical development program for omadacycline continues to progress well. We completed enrollment in March for our Phase 3 registration study of omadacycline in the treatment of acute bacterial skin and skin structure infections. We expect to report top-line data from this study as early as the end of this June. The second ongoing study in our Phase 3 registration program is for the treatment of community-acquired bacterial pneumonia. We are pleased to report that enrollment of this study is currently ahead of our initial projections; as such we are now expecting top-line data from this study as early as the third quarter of 2017,” said Michael Bigham, Chairman and Chief Executive Officer, Paratek. “We are also pleased to report that we have now initiated our Phase 1b study with omadacycline for the treatment of urinary tract infections.”

Recent Paratek Highlights

• Completed enrollment in the company’s Phase 3 registration study evaluating omadacycline for the treatment of Acute Bacterial Skin and Skin Structure Infections (ABSSSI) in March 2016, ahead of original projected timeline
• Faster-than-projected enrollment to date in the second Phase 3 registration study evaluating omadacycline for the treatment of community-acquired bacterial pneumonia (CABP). Enrollment for this study commenced in November 2015
• Initiated dosing in a Phase 1b study evaluating omadacycline for the treatment of urinary tract infections

Upcoming Milestones

• Readout of top-line data from pivotal Phase 3 registration study evaluating omadacycline for the treatment of ABSSSI expected as early as late June 2016
• Readout of top-line data from pivotal Phase 3 registration study evaluating omadacycline for the treatment of CABP now expected as early as the third quarter of 2017

Financial Results 
For the quarter ended March 31, 2016, Paratek reported a net loss of $31.3 million, or $1.78 per share, compared to a net loss of $10.6 million, or $0.74 per share, for the same period in 2015.

Research and development expenses were $24.3 million for the quarter ended March 31, 2016, compared to $6.7 million for the same period in 2015. The increase in research and development expense during the quarter ended March 31, 2016 was primarily the result of our ongoing clinical development of omadacycline. During the current quarter, we incurred approximately $14.4 million in expense associated with our Phase 3 studies of ABSSSI and CABP, an increase of $12.9 million compared to $1.5 million in the same period in prior year. This increase is associated primarily with faster-than-projected enrollment performance in both of the ABSSSI and CABP registration studies, resulting in an acceleration of related CRO fees, investigator fees, and costs associated with clinical sites and laboratories. This acceleration in the recognition of these expenses does not affect the aggregate expense levels from these studies, and as such does not affect our overall cash runway.  The remainder of the increase represents additional production costs for omadacycline registration batches, salaries and benefits, including stock-based compensation, due to increased headcount, and costs from omadacycline Phase 1 studies.

General and administrative expenses were $6.3 million for the quarter ended March 31, 2016, compared to $4.3 million for the same period in 2015. The increase in general and administrative costs for the quarter ended March 31, 2016 was primarily the result of salaries and benefits, including stock-based compensation, commensurate with the increase in headcount.

As of March 31, 2016, Paratek had cash, cash equivalents, and marketable securities of $112.3 million. Based on current assumptions, Paratek’s cash, cash equivalents and marketable securities are expected to fund operations through the read-out of top-line results from our second Phase 3 registration study, which is anticipated as early as the third 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. Paratek completed enrollment in a Phase 3 registration study in ABSSSI in March 2016 to determine the efficacy and safety of omadacycline compared to linezolid. Top-line data from this study is expected to be available as early as the end of June 2016. A Phase 3 registration study for CABP comparing omadacycline to moxifloxacin was initiated in November 2015 and top-line data is now expected as early as the third quarter of 2017. Paratek initiated a Phase 1b study of omadacycline in urinary tract infections in May 2016. Omadacycline has been granted 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, complicated urinary tract infections (cUTI), 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 new once-daily oral tetracycline-derived compound for the potential treatment of acne and rosacea in the community setting. Sarecycline is designed to be a well-tolerated, once-daily oral, narrow spectrum antibiotic with anti-inflammatory properties. 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.
