Nabriva Therapeutics has resubmitted the New Drug Application (NDA) for Contepo (fosfomycin for injection) for the treatment of complicated urinary tract infections (cUTIs), including acute pyelonephritis. 

Fosfomycin is a novel, epoxide intravenous antibiotic with a broad spectrum of Gram-negative and Gram-positive activity, including activity against multi-drug resistant (MDR) strains such as extended spectrum β-lactamase (ESBL)-producing Enterobacteriaceae. Compared with other injectable antibiotics, Contepo works by inhibiting cell wall formation at an early stage in cell wall synthesis.

The CRL directed the Company to address facility inspections and manufacturing deficiencies at 1 of their contract manufacturers, however, no request was made for new clinical data and no issues over safety were raised.
