-PDUFA action date set for August 19, 2019-


Nabriva Therapeutics plc (NASDAQ: NBRV), a clinical-stage biopharmaceutical company engaged in the research and development of innovative anti-infective agents to treat serious infections, announced that the U.S. Food and Drug Administration (FDA) has accepted the New Drug Applications (NDAs) and granted a priority review for both the intravenous (IV) and oral formulations of lefamulin, a potentially first-in-class, semi-synthetic pleuromutilin antibiotic, for the treatment of community-acquired bacterial pneumonia (CABP). The acceptance of lefamulin’s two NDAs indicates that the FDA has deemed both applications sufficiently complete to allow a substantive review. Both applications have been granted priority review and the Prescription Drug User Fee Act (PDUFA) goal date for the completion of the FDA’s review is August 19, 2019. In addition to priority review, lefamulin has been granted Qualified Infectious Disease Product (QIDP) and Fast Track designations by the FDA.

“Lefamulin is the second product candidate with an accepted NDA this year for Nabriva Therapeutics, supporting our commitment to bring novel anti-infective agents that address the urgent, unmet medical need in patients with serious infections,” said Dr. Jennifer Schranz, chief medical officer of Nabriva Therapeutics. “We believe lefamulin has the potential to provide a much-needed monotherapy treatment option for adults with CABP. As demonstrated in our clinical program, the ability to switch from IV to oral administration and the short-course oral regimen has the potential to position lefamulin, if approved, as a monotherapy option for patients in the hospital, transition of care and ambulatory care settings.”

The NDAs are supported by two pivotal, Phase 3 clinical trials (known as LEAP 1 and LEAP 2) that evaluated the safety and efficacy of IV and oral lefamulin compared to moxifloxacin in the treatment of adults with CABP. LEAP 1 was designed with the option to switch from IV to oral administration and LEAP 2 was designed as a short course, 5-day, oral only treatment with lefamulin. In both LEAP 1 and LEAP 2, lefamulin was demonstrated to be non-inferior to moxifloxacin, and met both the FDA and European Medicines Agency (EMA) primary and secondary efficacy endpoints for the treatment of CABP. Lefamulin was also shown to be generally well-tolerated when administered either orally or intravenously.

In the acceptance letter for the NDAs, the FDA stated that no filing or potential review issues were identified. In addition, the Agency stated that it is not currently planning to hold an advisory committee meeting to discuss these applications.


About CABP

Based on Nabriva Therapeutics’ combined analysis of the U.S. Centers for Disease Control and Prevention’s 2007 National Ambulatory Medical Care Survey, the National Hospital Ambulatory Medical Care Survey and 2013 data from the Healthcare Cost and Utilization Project, Nabriva Therapeutics estimates that more than five million adults are treated annually for CABP in the United States. Additionally, based on 2013 data from the Healthcare Cost and Utilization Project, Nabriva Therapeutics estimates that approximately three million of these adult CABP patients are diagnosed in an in-patient hospital and/or emergency department setting, where most are then treated with in-patient IV and oral antibiotics or out-patient oral antibiotics prescribed for use following hospital discharge or release.


About Lefamulin

Lefamulin is a semi-synthetic pleuromutilin antibiotic with potential to be first-in-class for systemic administration in humans discovered and developed by the Nabriva Therapeutics team. It is designed to inhibit the synthesis of bacterial protein, which is required for bacteria to grow. Lefamulin’s binding occurs with high affinity, high specificity and at molecular sites that are different than other antibiotic classes. Based on results from its two global, Phase 3 clinical trials, Nabriva Therapeutics believes lefamulin is well-positioned for use as a first-line monotherapy for the treatment of CABP due to its novel mechanism of action, targeted spectrum of activity, resistance profile, achievement of substantial drug concentration in lung tissue and fluid, availability of oral and IV formulations and a generally well-tolerated safety profile. Nabriva Therapeutics believes lefamulin represents a potentially important new treatment option for the approximately five to six million adults in the United States diagnosed with CABP each year.
