WEP-CLINICAL

WEP Clinical (WEP), a specialist pharmaceutical services company, has signed an exclusive agreement with Nabriva Therapeutics (Nabriva) to supply XENLETA^® (lefamulin) on a named patient or expanded access basis. The Named Patient Program (NPP) is designed to ensure that physicians, contingent on meeting the necessary eligibility criteria and receiving approval, can request IV or oral XENLETA on behalf of patients who live in certain countries where it is not yet available.

XENLETA was discovered and developed by Nabriva (NASDAQ: NBRV), a commercial-stage biopharmaceutical company focused on commercialization and development of anti-infective agents. It is approved by the U.S. Food and Drug Administration (FDA) for the treatment of adults with community-acquired bacterial pneumonia (CABP) caused by susceptible microorganisms. XENLETA is the first and only oral and IV pleuromutilin empiric antibiotic that acts against the pathogens that commonly cause CABP.

Nabriva announced on May 29th that the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) adopted a positive opinion recommending approval of XENLETA 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.

Under the terms of the NPP, XENLETA will be made available in two formulations - 150mg injection for intravenous administration and 600mg oral tablets - using named patient or expanded access managed by WEP to enable healthcare professionals to access XENLETA for patients that have an unmet clinical need. Once a request is approved, WEP will manage the distribution of XENLETA to the treating physician and will provide any necessary follow-up support and services.

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.

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.
