Paratek Pharmaceuticals to Present Data at ICAAC 2015

BOSTON, Aug. 3, 2015 (GLOBE NEWSWIRE) -- Paratek Pharmaceuticals, Inc. (Nasdaq:PRTK), a biopharmaceutical company focused on the development and commercialization of innovative therapies based upon tetracycline chemistry, announced today that data from microbiology testing of omadacycline will be presented at the Interscience Conference of Antimicrobial Agents and Chemotherapy/International Congress of Chemotherapy and Infection. Known as ICAAC/ICC2015, the conference will be held September 17 – 21 in San Diego, California. Omadacycline is a once-daily oral and intravenous, broad-spectrum antibiotic currently in clinical development.

"There is an urgent need for new antibiotics to address the growing challenge of resistance," said Evan Loh, M.D., President and Chief Medical Officer, Paratek Pharmaceuticals. "The breadth of omadacycline data being presented at ICAAC in September reinforces the potential of this compound to be an important treatment option in the hospital and community setting. We look forward to sharing this information with the treatment and scientific communities."

About Paratek

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 an aminomethylcycline, derived from tetracyclines. Paratek initiated a Phase 3 registration study in ABSSSI in June to determine the efficacy and safety of omadacycline compared to linezolid. A Phase 3 registration study for CABP with omadacycline is planned to be initiated before the end of 2015.

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 (ABSSSI), community acquired bacterial pneumonia (CABP), urinary tract infections (UTI), and other community-acquired bacterial infections, particularly when antibiotic resistance is of concern to prescribing physicians.

Paratek's second product candidate, sarecycline, also known as WC 3035, is a new once-daily oral tetracycline-derived compound, designed to provide both a narrow-spectrum of antibiotic activity and favorable tolerability profile, for the treatment of acne and rosacea in the community setting. Paratek has licensed rights to sarecycline for the treatment of acne in the United States to a subsidiary of Allergan, formerly Warner Chilcott, while retaining rights in the rest of the world. Allergan is responsible for the clinical development of sarecycline for the treatment of acne in the United States. A Phase 3 program was initiated by Allergan in December 2014 for sarecycline for the treatment of moderate to severe acne vulgaris.
