Iterum Therapeutics Announces NDA for Oral Sulopenem

Iterum Therapeutics announced the U.S. Food and Drug Administration (FDA) accepted for review the New Drug Application (NDA) for sulopenem etzadroxil/probenecid (oral sulopenem) for the treatment of uncomplicated urinary tract infections (uUTIs) in patients with a quinolone non-susceptible pathogen. The FDA has designated this application as a priority review and consequently assigned a PDUFA (Prescription Drug User Fee Act) goal date for completion of the review of oral sulopenem of July 25, 2021. The agency currently plans to hold an advisory committee meeting to discuss the NDA.

“The FDA acceptance of our NDA for review is an important milestone for Iterum. If approved, oral sulopenem would be the first penem available orally in the U.S. with the ability to treat multi-drug resistant infections in the community,” said Corey Fishman, Chief Executive Officer. “Specifically, this important antibiotic is one step closer to relieving the growing problem of quinolone resistance found in over six million uncomplicated urinary tract infections in the U.S. each year."

The NDA includes data from the SURE-1, SURE-2 and SURE-3 phase 3 clinical trials, in which oral sulopenem was well tolerated. 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.
