ContepoTreatment for Urinary Tract Infection
Nabriva Therapeutics Receives FDA Acknowledgement of New Drug Application Resubmission for Intravenous Contepo (fosfomycin) for Injection
DUBLIN, Ireland, Jan. 08, 2020 (GLOBE NEWSWIRE) -- Nabriva Therapeutics plc (NASDAQ: NBRV), a commercial-stage biopharmaceutical company engaged in the development of innovative anti-infective agents to treat serious infections, announced that the U.S. Food and Drug Administration (FDA) has acknowledged receipt of its New Drug Application (NDA) resubmission for marketing approval of Contepo (fosfomycin) for injection for the treatment of complicated urinary tract infections (cUTIs).
In the acknowledgement letter for the resubmitted NDA, the FDA stated that Nabriva’s filing was a complete, class 2 response to the complete response letter the FDA issued on April 30, 2019. As a result, the FDA set a Prescription Drug User Fee Act (PDUFA) goal date of June 19, 2020 for the completion of its review of the NDA.
Contepo is a potential first-in-class intravenous antibiotic in the U.S. for the treatment of cUTIs. The NDA resubmission is supported by data from a pivotal Phase 2/3 clinical trial (known as ZEUS™), which met its primary endpoint of statistical non-inferiority to piperacillin/tazobactam in patients with cUTI, including acute pyelonephritis.
Complicated Urinary Tract Infection
Complicated urinary tract infection (cUTI) occurs when Gram-negative bacteria are embedded in the bladder wall where they can multiply more slowly and are much harder to address with antibiotics. Patients who are being treated for a urinary tract infection and fail to respond to an initial course of antibiotics can go on to develop a cUTI.
Among the causes of cUTI is Enterobacteriaceae, which is a multi-drug resistance (MDR) strain of Gram-negative bacteria. Enterobacteriaceae produces extended spectrum beta-lactamases (ESBL), a chemical that can cause some antibiotics to be ineffective in treating bacterial infections such as cUTI. As a result, cUTI poses a serious and rapidly emerging health threat for hospitalized patients, especially those in intensive care units.
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.
