DUBLIN, Ireland, Sept. 26, 2019 (GLOBE NEWSWIRE) — Nabriva Therapeutics plc (NASDAQ: NBRV), a biopharmaceutical company engaged in the commercialization and development of innovative anti-infective agents to treat serious infections, announced today that data from its XENLETA™ (lefamulin) and CONTEPO™ (fosfomycin) clinical development programs will be presented at IDWeek 2019, to be held October 2-9 in Washington, D.C.

Nabriva, along with its collaborators, will present a total of 14 posters, including 11 for lefamulin and three for fosfomycin. Lefamulin data being presented has been generated from the company’s community-acquired bacterial pneumonia (CABP) clinical trial and in vitro surveillance programs. In addition, the company will present clinical data for CONTEPO from the Phase 2/3 pivotal study for the treatment of complicated urinary tract infections (cUTIs) as well as epidemiologic and prevalence data of U.S. hospitalized patients with difficult-to-treat, drug-resistant uropathogens, e.g., Enterobacteriaciae and P. aeruginosa.

XENLETA is the first oral and intravenous (IV) treatment in the pleuromutilin class of antibiotics. XENLETA was approved by the U.S. Food and Drug Administration (FDA) on August 19, 2019 for the treatment of adults with CABP and is now commercially available in the United States. Nabriva plans to resubmit the new drug application (NDA) for CONTEPO early in the fourth quarter of 2019.

“We are excited to share our latest clinical data on the safety and efficacy of XENLETA and CONTEPO with the infectious disease community at IDWeek,” said Jennifer Schranz MD, Chief Medical Officer of Nabriva Therapeutics. “Our rigorous clinical trial programs continue to generate meaningful information that we believe will aid clinicians in determining the most appropriate treatment choice for their patients with CABP or cUTIs. We are proud to be working to provide patients and the infectious diseases community two new antibiotics with critically needed novel mechanisms of action that address several of the Centers for Disease Control (CDC) Urgent Threat and World Health Organization (WHO) priority pathogens.”

About Nabriva Therapeutics plc
Nabriva Therapeutics is a biopharmaceutical company engaged in the commercialization and development of innovative anti-infective agents to treat serious infections. Nabriva Therapeutics received U.S. Food and Drug Administration approval for XENLETA™ (lefamulin), the first systemic pleuromutilin antibiotic for community-acquired bacterial pneumonia (CABP). Nabriva Therapeutics is also developing CONTEPO™ (fosfomycin) for injection, a potential first-in-class epoxide antibiotic for complicated urinary tract infections (cUTI), including acute pyelonephritis. For more information, please visit www.nabriva.com.

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. IV fosfomycin has been approved for a number of indications and utilized for over 45 years outside the U.S. 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 an early appropriate treatment for cUTIs, including acute pyelonephritis, suspected to be caused by MDR pathogens. An estimated 40 percent of cUTIs are suspected to be caused by MDR bacteria and limited treatment options are available in the U.S. for these patients.

About XENLETA
XENLETA (lefamulin) is a first-in-class semi-synthetic pleuromutilin antibiotic 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. XENLETA’s binding occurs with high affinity, high specificity and at molecular sites that are different than other antibiotic classes. Efficacy of XENLETA was demonstrated in two multicenter, multinational, double-blind, double-dummy, non-inferiority trials assessing a total of 1,289 patients with CABP.  In these trials, XENLETA was compared with moxifloxacin and in one trial, moxifloxacin with and without linezolid. Patients who received XENLETA had similar rates of efficacy as those taking moxifloxacin alone or moxifloxacin plus linezolid. The most common adverse reactions associated with XENLETA include diarrhea, nausea, reactions at the injection site, elevated liver enzymes, and vomiting.

INDICATION AND IMPORTANT SAFETY INFORMATION

INDICATION

XENLETA is a pleuromutilin antibacterial indicated for the treatment of adults with community-acquired bacterial pneumonia (CABP) caused by the following susceptible microorganisms: Streptococcus pneumoniae, Staphylococcus aureus (methicillin-susceptible isolates), Haemophilus influenzae, Legionella pneumophila, Mycoplasma pneumoniae, and Chlamydophila pneumoniae.

USAGE

To reduce the development of drug-resistant bacteria and maintain the effectiveness of XENLETA and other antibacterial drugs, XENLETA should be used only to treat or prevent infections that are proven or strongly suspected to be caused by susceptible bacteria.

IMPORTANT SAFETY INFORMATION

CONTRAINDICATIONS

XENLETA is contraindicated in patients with known hypersensitivity to XENLETA or pleuromutilins.

XENLETA tablets are contraindicated for use with CYP3A4 substrates that prolong the QT interval.

WARNINGS AND PRECAUTIONS

XENLETA has the potential to prolong the QT interval. Avoid XENLETA in patients with known QT prolongation, ventricular arrhythmias, and patients receiving drugs that may prolong the QT interval.

Based on animal studies, XENLETA may cause fetal harm. Advise females of reproductive potential of the potential risk to the fetus and to use effective contraception.

Clostridium difficile-associated diarrhea (CDAD) has been reported with nearly all systemic antibacterial agents, including XENLETA, with severity ranging from mild diarrhea to fatal colitis. Evaluate if diarrhea occurs.

ADVERSE REACTIONS

The most common adverse reactions (≥2%) for (a) XENLETA Injection are administration site reactions, hepatic enzyme elevation, nausea, hypokalemia, insomnia, and headache and (b) XENLETA Tablets are diarrhea, nausea, vomiting, and hepatic enzyme elevation.

USE IN SPECIFIC POPULATIONS

In patients with severe hepatic impairment, reduce the dosage of XENLETA Injection to 150 mg infused over 60 minutes every 24 hours. XENLETA Tablets are not recommended in patients with moderate or severe hepatic impairment due to insufficient information to provide dosing recommendations.

Avoid XENLETA Injection and Tablets with concomitant strong or moderate CYP3A or P-gp inducers. Monitor for reduced efficacy of XENLETA.

Avoid XENLETA Tablets with strong CYP3A or P-gp inhibitors.

Monitor for adverse reactions of sensitive CYP3A substrates administered with XENLETA Tablets.

XENLETA has not been studied in pregnant women. Verify pregnancy status in females prior to initiating XENLETA and advise females to use contraception during treatment and for 2 days after the final dose. Lactating women should pump and discard milk for the duration of treatment with XENLETA and for 2 days after the final dose.

To report SUSPECTED ADVERSE REACTIONS, or administration during pregnancy, contact Nabriva Therapeutics US, Inc. at 1-855-5NABRIVA or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch.
