Nabriva To Present Data At ASM Microbe Supporting Ongoing Phase III Clinical Development Program For Lefamulin

- Four abstracts demonstrate potential for lefamulin as a first-line, empiric treatment for patients with community-acquired bacterial pneumonia

VIENNA, Austria and KING OF PRUSSIA, Pa., June 02, 2017 (GLOBE NEWSWIRE) -- Nabriva Therapeutics AG (NASDAQ:NBRV), a clinical-stage biopharmaceutical company engaged in the research and development of novel anti-infective agents to treat serious infections, with a focus on the pleuromutilin class of antibiotics, today announced that data will be presented at the American Society for Microbiology (ASM) Microbe 2017 conference in New Orleans, LA from June 1-5, 2017.

The company will showcase four poster presentations on lefamulin’s in vitro activity against key pathogens commonly causing respiratory tract infections. These data are part of a growing body of evidence supporting lefamulin’s profile as a potential first-line, empiric treatment for the key pathogens, including multidrug resistant strains, that are known to cause community-acquired bacterial pneumonia (CABP).

“Antibacterial resistance continues to spread, rendering currently available antibiotics less effective. It is critical that new antibiotic classes continue to be developed to provide physicians treatment options for patients with serious infections,” said Steven P. Gelone, Pharm.D., Chief Development Officer at Nabriva. “Lefamulin possesses a novel mechanism of action and provides a targeted spectrum of activity that covers the most common bacterial and atypical pathogens that cause CABP, including multi-drug resistant strains. The data presented at ASM Microbe 2017 are supportive of our ongoing Phase 3 clinical development program and we look forward to reporting top-line results from our first pivotal trial, known as LEAP 1, in the third quarter of 2017.”

The below four abstracts to be presented at ASM Microbe 2017 add to a growing compendium of data demonstrating lefamulin’s in vitro activity against the key bacteria known to cause CABP, including multidrug resistant strains.

About CABP

Based on a 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 estimates that over 5 million adults are treated annually for CABP in the United States.  Additionally, based on 2013 data from the Healthcare Cost and Utilization Project, Nabriva estimates that approximately 3 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 LEAP 1 and LEAP 2 Clinical Trial Design

Nabriva’s first pivotal Phase 3 clinical trial, LEAP 1, is a multi-center, randomized, controlled, double-blind, international study comparing lefamulin to moxifloxacin, a fluoroquinolone antibiotic. LEAP 1 is designed to evaluate the efficacy and safety of lefamulin (IV/oral) compared to moxifloxacin (IV/oral), with or without linezolid, in 550 patients with moderate to severe CABP. Linezolid (or matching placebo for the lefamulin arm), can be added to treatment if an investigator suspects that a patient is infected with methicillin-resistant S. aureus (MRSA) prior to randomization, as moxifloxacin is not approved to treat MRSA. All patients enrolled in this trial have a Pneumonia Outcomes Research Team (PORT) severity of at least 3 on a scale of 1 to 5, which corresponds to moderate to severe clinical disease. Nabriva’s second pivotal Phase 3 clinical trial, LEAP 2, is a multi-center, randomized, controlled, double-blind, international study comparing oral lefamulin to moxifloxacin. LEAP 2 is designed to evaluate the efficacy and safety of oral lefamulin compared to oral moxifloxacin in subjects with moderate CABP. All patients enrolled in this trial have a PORT severity of 2 to 4 on a scale of 1 to 5, which corresponds to moderate disease. Nabriva is targeting the enrollment of approximately 738 patients in LEAP 2. Both Phase 3 clinical trials of lefamulin were designed to follow draft guidance published by the U.S. Food and Drug Administration for the development of drugs for CABP and guidance from the European Medicines Agency for the development of antibacterial agents.

About Nabriva Therapeutics AG

Nabriva Therapeutics is a clinical stage biopharmaceutical company engaged in the research and development of novel anti-infectives to treat serious bacterial infections, with a focus on the pleuromutilin class of antibiotics. Nabriva Therapeutics’ medicinal chemistry expertise has enabled targeted discovery of novel pleuromutilins, including both intravenous and oral formulations of its lead product candidate. Nabriva Therapeutics’ lead product candidate, lefamulin, is a novel semi-synthetic pleuromutilin antibiotic with the potential to be the first-in-class available for systemic administration in humans. The Company believes that lefamulin is the first antibiotic with a novel mechanism of action to have reached late-stage clinical development in more than a decade. Lefamulin is currently being evaluated in two global, registrational Phase 3 clinical trials in patients with moderate to severe CABP. Nabriva Therapeutics believes lefamulin is well positioned for use as a first-line empiric monotherapy for the treatment of moderate to severe CABP due to its novel mechanism of action, targeted spectrum of activity, resistance profile, achievement of substantial drug concentration in lung tissue and fluid, oral and IV formulations and a favorable tolerability profile. Nabriva Therapeutics intends to further pursue development of lefamulin for additional indications, including the treatment of acute bacterial skin and skin structure infections (ABSSSI), and is developing a formulation of lefamulin appropriate for pediatric use.

Nabriva Therapeutics owns exclusive, worldwide rights to lefamulin, which is protected by composition of matter patents issued in the United States, Europe and Japan.
