FDA Advisory Committee Recommends Approval of Paratek’s Omadacycline

-- Positive vote for both the skin infections and pneumonia indications --

-- FDA decision expected in early October 2018 --

BOSTON, Aug. 08, 2018 (GLOBE NEWSWIRE) -- Paratek Pharmaceuticals, Inc. (NASDAQ: PRTK) today announced that the Antimicrobials Drug Advisory Committee of the U.S. Food and Drug Administration voted in favor of the approval of intravenous (IV) and oral omadacycline for the treatment of acute bacterial skin and skin structure infections (ABSSSI) (17-1) and community-acquired bacterial pneumonia (CABP) (14-4).  Omadacycline is a modernized tetracycline being developed as a once-daily IV and oral, broad spectrum antibiotic for the treatment of serious community-acquired infections.

“Omadacycline has the potential to help address the urgent and growing need for new antibiotics to treat serious community-acquired infections. With once-daily dosing and bioequivalent IV and oral formulations, omadacycline may help facilitate early discharge from the hospital or, in other cases, allow for safe and effective treatment in the outpatient setting,” said Michael F. Bigham, Chairman and CEO, Paratek. “Today’s recommendations from the Advisory Committee move us one step closer to making this important new treatment option available to patients and physicians. We look forward to working with the FDA as it considers the comments from the committee members and completes its review of the omadacycline new drug applications.”

As part of its recommendation, the Advisory Committee considered data from the omadacycline global development program, which included three completed Phase 3 studies evaluating the safety and efficacy of the once-daily IV and oral formulations of omadacycline for the treatment of ABSSSI and CABP. In all three studies, omadacycline met all primary and secondary efficacy outcomes designated by the FDA and was generally safe and well-tolerated. A total of nearly 2,000 adult patients received omadacycline administered once-daily as part of the clinical trials. The Advisory Committee was asked to vote on whether the data provided substantial evidence of the safety and effectiveness of omadacycline in both ABSSSI and CABP.

The Prescription Drug User Fee Act (PDUFA) date for both new drug applications is in early October 2018.

About Omadacycline

Omadacycline is a novel investigational antibiotic with both once-daily intravenous (IV) and oral formulations for the treatment of community-acquired bacterial pneumonia (CABP), acute bacterial skin and skin structure infections (ABSSSI), and urinary tract infections (UTI). A modernized tetracycline, omadacycline is specifically designed to overcome tetracycline resistance and exhibits activity across a broad spectrum of bacteria, including Gram-positive, Gram-negative, anaerobes, atypical bacteria, and other drug-resistant strains.

Omadacycline has been granted Qualified Infectious Disease Product designation and Fast Track status by the U.S. Food and Drug Administration (FDA) for the target indications of CABP, ABSSSI, and UTI. The FDA has accepted the New Drug Applications for CABP and ABSSSI and has granted omadacycline priority review. Paratek is also preparing a marketing authorization application in the European Union. 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.
