BOSTON, June 07, 2018 (GLOBE NEWSWIRE) -- Paratek Pharmaceuticals, Inc. (Nasdaq:PRTK) announced today that data from its omadacycline clinical and microbiology programs will be presented at the American Society for Microbiology’s annual ASM Microbe 2018 meeting taking place from June 7-11 in Atlanta, GA. The data continue to highlight the robust 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).

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. The Company’s lead product candidate, omadacycline, is a new, once-daily oral and intravenous broad-spectrum antibiotic being developed for the treatment of serious community-acquired bacterial infections, including community-acquired bacterial pneumonia (CABP), acute bacterial skin and skin structure infections (ABSSSI), and urinary tract infections (UTI). Omadacycline has been granted Qualified Infectious Disease Product designation and Fast Track status by the U.S. Food and Drug Administration for the target indications of ABSSSI, CABP, and UTI. Paratek has completed Phase 3 development activities for omadacycline in CABP and ABSSSI, and its New Drug Applications to the U.S. FDA have been accepted for priority review. The Company plans to submit a marketing authorization in the European Union in the second half of this year. Paratek has entered into a collaboration agreement with Zai Lab for the development and commercialization of omadacycline in the greater China region, and retains all remaining global rights.

Under a research agreement with the U.S. Department of Defense, omadacycline also is being studied against pathogenic agents causing infectious diseases of public health and biodefense importance, including plague and anthrax.

Paratek's second product candidate, SEYSARA™ (sarecycline), is being developed by Allergan in the U.S. as a new once-daily oral therapy for the treatment of acne. Allergan has completed Phase 3 development activities for Seysara and its new drug application was accepted for review by the U.S. FDA in December 2017. Paratek retains all ex-U.S. rights to sarecycline.

Recognizing the serious threat of bacterial infections, Paratek is dedicated to providing solutions that enable positive outcomes and lead to better patient stories.
