DUBLIN, Ireland, May 29, 2020 (GLOBE NEWSWIRE) --Nabriva Therapeutics plc (NASDAQ: NBRV) announced today that the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) has adopted a positive opinion recommending approval of XENLETA (lefamulin) for the treatment of community-acquired pneumonia (CAP) in adults when it is considered inappropriate to use antibacterial agents that are commonly recommended for the initial treatment of CAP or when these have failed. The CHMP opinion will be reviewed by the European Commission (EC), which has the authority to approve medicines for all 28 countries of the European Union, Norway, Iceland, and Liechtenstein. A regulatory decision is anticipated during the second half of 2020.
“Today’s announcement brings us one step closer to the first approval of a new class of antibiotics for patients with community-acquired pneumonia in Europe in almost 20 years,” said Jennifer Schranz, MD, Chief Medical Officer of Nabriva. “XENLETA has a novel mechanism of action and provides an urgently needed short course, empiric monotherapy treatment alternative for adult patients with CAP. We look forward to the European Commission’s decision and the opportunity to bring this important medicine to patients.”
The CHMP recommendation for marketing authorization is based on efficacy data from the Lefamulin Evaluation Against Pneumonia (LEAP) 1 and LEAP 2 studies and a safety database of 1,242 study participants.
In the two Phase 3 clinical trials, the EMA co-primary endpoint was the Investigator Assessment of Clinical Response (IACR) at Test of Cure (TOC) in both the clinically evaluable (CE) and modified intent-to-treat (mITT) populations. Both studies established XENLETA to be non-inferior to the standard-of-care moxifloxacin in the treatment of adults with CAP independently and when the pooled data were analyzed across PORT scores of II-V. In the pooled analysis, the IACR success rate at TOC in the modified Intent-to-Treat (mITT) population was 85 percent in the XENLETA group and 87.1 percent in the moxifloxacin group (treatment difference ‑2.2 percent; 95 percent confidence interval (CI): ‑5.9, 1.6), and 88.5 percent in the lefamulin group and 91.8 percent in the moxifloxacin group (treatment difference ‑3.3 percent; 95 percent CI: ‑6.8, 0.1) in the Clinically Evaluable population. In these trials, lefamulin was generally well-tolerated. The most frequently reported adverse reactions are administration site reactions, diarrhea, nausea, vomiting, hepatic enzyme elevation, headache, hypokalemia, and insomnia.
The European Commission will review the CHMP recommendation and typically delivers its final decision in approximately two months. The U.S. Food and Drug Administration (FDA) approved XENLETA in August 2019 for the treatment of adult patients with community-acquired bacterial pneumonia (CABP).

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 frequently reported adverse reactions are administration site reactions (7%), diarrhea (7%), nausea (4%), vomiting (2%), hepatic enzyme elevation (2%), headache (1%), hypokalaemia (1%), and insomnia (1%). Administration site reactions led to discontinuation in <1%; gastrointestinal disorders were predominantly associated with the oral formulation and led to treatment discontinuation in <1%.
