Paratek Completes Submission of New Drug Applications to U.S. Food and Drug Administration for Oral and Intravenous Omadacycline for Pneumonia and Skin Infections

BOSTON, Feb. 05, 2018 (GLOBE NEWSWIRE) -- Paratek Pharmaceuticals, Inc. (Nasdaq:PRTK) announced today that on February 2, 2018, it completed the submission of two New Drug Applications (NDAs) to the U.S. Food and Drug Administration (FDA) for the Company’s once-daily oral and IV formulations of its broad-spectrum investigational antibiotic, omadacycline. Omadacycline is the first in a new class of tetracycline antibiotics known as aminomethylcyclines. Paratek is seeking FDA approval for omadacycline for the treatment of community-acquired bacterial pneumonia (CABP) and acute bacterial skin and skin structure infections (ABSSSI), based on the results of three successful Phase 3 pivotal studies. The FDA has previously granted omadacycline both Qualified Infectious Disease Product and Fast Track designation for these indications, which provide for a Priority Review of the NDAs, once accepted.

“The completion of our NDA submissions marks a significant milestone for Paratek and we are deeply grateful to the patients, investigators, and entire Paratek team for their commitment to advancing omadacycline’s development path to this major milestone,” said Evan Loh, MD, President, COO & CMO of Paratek. “With antibiotic resistance on the rise, we look forward to working with the FDA during the regulatory review process with the goal of bringing a modernized tetracycline antibiotic, omadacycline, to clinicians and patients for the treatment of serious community-acquired bacterial infections.”

The NDAs are supported by the Company’s Phase 3 program for omadacycline, which includes three pivotal registration trials: two studies in ABSSSI and one study in CABP. Omadacycline met all FDA and European Medicines Agency (EMA) primary endpoints in each study and demonstrated a generally safe and well-tolerated profile.
