-NTAP designation highlights need for novel antibiotics to fight drug-resistant infections and advance antimicrobial stewardship

-CONTEPO first Qualified Infectious Disease Product to receive NTAP conditional approval prior to FDA approval

DUBLIN, Ireland, Sept. 10, 2020 (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 the Centers for Medicare & Medicaid Services (CMS) has granted a new technology add-on payment (NTAP) for XENLETA (lefamulin) for injection when administered in the hospital inpatient setting. XENLETA is a pleuromutilin antibacterial indicated for the treatment of adults with community-acquired bacterial pneumonia (CABP). Both the IV and oral formulations of XENLETA were granted Qualified Infectious Disease Product (QIDP) and Fast Track designation by the FDA.

Beginning on October 1, 2020, CMS will provide an additional maximum payment of $1,275.75 for XENLETA when used in the inpatient hospital setting for fiscal year 2021. The U.S. Food and Drug Administration (FDA) approved the IV and oral versions of XENLETA for the treatment of adult patients with CABP in August 2019.

Nabriva also announced today that CMS has granted an NTAP for CONTEPO (fosfomycin), making CONTEPO the first QIDP to be granted conditional NTAP approval prior to receiving FDA approval. CONTEPO was granted QIDP and Fast Track Designation by the FDA for the treatment of complicated urinary tract infections (cUTI), including acute pyelonephritis. If CONTEPO receives FDA approval prior to July 1, 2021, the maximum add-on payment for a case involving the administration of CONTEPO is $2,343.75 for fiscal year 2021, which would become effective beginning in the first quarter after FDA approval is granted.

The NTAP will provide hospitals with a payment on top of the standard-of-care Diagnostic Related Group (DRG) reimbursement. This additional payment is provided to offset some of the costs of new drugs and devices when certain criteria are met. For the fiscal year 2021, add-on payments for QIDPs are limited to the lesser of 75 percent of the average cost of the product, or 75 percent of the amount by which the costs of the case exceeds the standard DRG payment. NTAP designation lasts no more than three years for a specific indication.

“The NTAP designation highlights the potential of XENLETA and CONTEPO to address the urgent need for novel, first-in-class antibiotics for patients fighting drug-resistant infections,” said Ted Schroeder, Chief Executive Officer of Nabriva Therapeutics. “Importantly, the decision to grant conditional NTAP approval to CONTEPO is unprecedented and we believe should enable more rapid access to this innovative antimicrobial following FDA approval. We applaud CMS for taking the initial policy steps that will enable patients in need to be prescribed innovative antibacterial agents and help reverse the consequences of antimicrobial resistance.”

The NTAP program for antimicrobial resistance (AMR) is intended to encourage the use of new medical technologies in the hospital inpatient setting and help reduce barriers to antibiotic innovation.

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.

About CONTEPO

CONTEPO (fosfomycin) for injection 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 extended spectrum β-lactamase (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.

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.
