DUBLIN, Ireland, Dec. 20, 2018 (GLOBE NEWSWIRE) — 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 the submission of two New Drug Applications (NDAs) to the U.S. Food and Drug Administration (FDA) for the oral and intravenous (IV) formulations of lefamulin, a first-in-class, semi-synthetic pleuromutilin antibiotic, for the treatment of community-acquired bacterial pneumonia (CABP). Both formulations of lefamulin were granted Qualified Infectious Disease Product and Fast Track designation by the FDA, enabling potential Priority Review of the NDAs by the FDA. Nabriva Therapeutics plans to submit a marketing authorization application for lefamulin in Europe in the first quarter of 2019.
“The submission of the lefamulin NDAs marks another major milestone for Nabriva Therapeutics, demonstrating our commitment to develop novel anti-infective agents that address the urgent, unmet medical need faced by patients with serious infections,” said Dr. Jennifer Schranz, chief medical officer of Nabriva Therapeutics. “Together with our CONTEPO™ NDA submission, we are one-step closer to offering US clinicians two, novel, first-in-class antibiotics. We believe lefamulin has the potential to provide a much-needed monotherapy treatment option for adults with CABP in both the hospital and ambulatory care settings. We are grateful to the patients and investigative sites who have supported the development of lefamulin for treatment of CABP.”
The two 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, including the option to switch from IV to oral administration and a short course oral 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.
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.
About CONTEPO™
CONTEPO™ (fosfomycin for injection, previously referred to as ZTI-01 and ZOLYD) is a novel, potentially first-in-class in the United States, intravenous investigational antibiotic with a broad spectrum of Gram-negative and Gram-positive activity, including activity against most contemporary multi-drug resistant (MDR) strains such as ESBL-producing Enterobacteriaceae. Intravenous (I.V.) fosfomycin has been approved for a number of indications and utilized for over 45 years in Europe to treat a variety of infections, including cUTIs and other serious bacterial infections. CONTEPO utilizes a new dosing approach, originally developed by Zavante (which Nabriva Therapeutics acquired), to optimize its pharmacokinetics and pharmacodynamics. Nabriva Therapeutics believes these attributes, along with the positive clinical experience worldwide, support CONTEPO as a first-line treatment for cUTIs, including acute pyelonephritis, suspected to be caused by MDR pathogens. At least 20 percent of cUTIs are caused by MDR bacteria and limited treatment options are available in the U.S. In addition, non-clinical data have shown that CONTEPO acts in combination with certain other antibiotics to improve bacterial killing.
About Nabriva Therapeutics plc
Nabriva Therapeutics is a clinical-stage biopharmaceutical company engaged in the research and development of innovative anti-infective agents to treat serious infections. Nabriva Therapeutics has two product candidates that are in late stage development: lefamulin, potentially the first systemic pleuromutilin antibiotic for CABP and CONTEPO (fosfomycin for injection), a potential first-in-class epoxide antibiotic in the United States for complicated urinary tract infections (cUTIs) including acute pyelonephritis (AP).
