- First oral presentation of the results of OASIS-2, the Phase 3 omadacycline oral-only study in ABSSSI

- Poster presentations include new microbiology analyses from OASIS-2

BOSTON, April 12, 2018 (GLOBE NEWSWIRE) -- Paratek Pharmaceuticals, Inc. (Nasdaq:PRTK) announced today that data from its omadacycline clinical and microbiology programs will be presented at the annual meeting of the European Congress of Clinical Microbiology and Infectious Diseases, ECCMID 2018, to be held April 21 – 24 in Madrid, Spain. The data continue to highlight the compelling efficacy and safety profile of omadacycline, an investigational once-daily oral and intravenous (IV) monotherapy antibiotic, for the treatment of community-acquired infections including community-acquired bacterial pneumonia (CABP) and acute bacterial skin and skin structure infections (ABSSSI).

“We are excited to share data from nine posters and one oral presentation at ECCMID this year. Each of these presentations add to the growing body of evidence of omadacycline's utility against relevant pathogens and life-threatening infections such as CABP and ABSSSI,” said Evan Loh, M.D., President, Chief Operating Officer, and Chief Medical Officer, Paratek. “These considerable efforts represent our ongoing commitment to making our data accessible to practicing physicians.”

Paratek’s Phase 3 study of the oral-only dosing of omadacycline in ABSSSI is known as the Omadacycline Acute Skin and Skin Structure Infections Study (OASIS-2).
