Agency Cited Travel Restrictions and Inability to Conduct Onsite Inspections to Resolve Observations at Manufacturing Partner Facilities
Agency Cited Travel Restrictions and Inability to Conduct Onsite Inspections to Resolve Observations at Manufacturing Partner Facilities
DUBLIN, Ireland, June 19, 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 it received a Complete Response Letter (CRL) from the U.S. Food and Drug Administration (FDA) for the New Drug Application (NDA) resubmission seeking marketing approval of CONTEPO (fosfomycin) for injection for the treatment of complicated urinary tract infections (cUTI), including acute pyelonephritis.
Although Nabriva’s European contract manufacturing partners were prepared for regulatory authority inspections, the CRL cites observations at our manufacturing partners that could not be resolved due to FDA’s inability to conduct onsite inspections because of travel restrictions. In general, previously identified product quality and facility inspection related observations at our contract manufacturing partners are required to be satisfactorily resolved before the NDA may be approved. The FDA did not request any new clinical data and did not raise any other concerns with regard to the safety or efficacy of CONTEPO in the CRL. Nabriva plans to request a Type A meeting with the FDA to discuss appropriate next steps and the FDA’s plans for completing foreign facility inspections. CONTEPO has been granted Qualified Infectious Disease Product (QIDP) and Fast Track designations by the FDA for the treatment of serious infections, including cUTI.
Complicated Urinary Tract Infection
Complicated urinary tract infections represent a serious infection in patients with underlying functional or structural abnormality of the urinary tract or in the presence of catheterization, and includes patients with acute pyelonephritis, regardless of underlying abnormalities of the urinary tract. An estimated three million cases of Gram-negative cUTIs are treated in the U.S. hospital setting annually, where approximately 40 percent of cases are suspected to be caused by resistant strains. Ineffectively managed cUTIs can lead to increased treatment failure rates, which in turn, can result in prolonged hospital stays, recurrence, re-hospitalization, and mortality – each of which poses a substantial resource and economic burden on the healthcare and payer systems.
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.
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.
