Iterum Therapeutics has submitted its New Drug Application (NDA) to the U.S. Food and Drug Administration (FDA) for sulopenem etzadroxil/probenecid (oral sulopenem) for the treatment of uncomplicated urinary tract infections (uUTIs) in patients with a quinolone non-susceptible pathogen.

“The submission of the NDA filing for oral sulopenem is a significant step forward in bringing new antibiotics to patients to help address the challenge of antibiotic resistance,” said Corey Fishman, Chief Executive Officer. “Oral sulopenem, if approved, would mean that physicians and patients have the opportunity to benefit from the proven efficacy and safety of penem antibiotics that, to date in the U.S., have only been available in IV formulations. We are now one step closer to realizing the goal of bringing this much needed medicine to the over six million patients with cipro-resistant UTIs each year in the U.S.”

The NDA submission includes data from the SURE-1, SURE-2 and SURE-3 phase 3 clinical trials, in which oral sulopenem was well tolerated with no significant drug related adverse events. The SURE-1 clinical trial (uUTIs) demonstrated statistical superiority of oral sulopenem to the widely used comparator, ciprofloxacin, for the primary efficacy endpoint of clinical and microbiologic response at the test-of-cure visit for patients with a quinolone non-susceptible pathogen.
