Iterum Therapeutics Provides Update on FDA Advisory Committee Discussion of Oral Sulopenem for the Treatment of uUTI in Adult Women

FDA Decision Expected by PDUFA Goal Date of October 25, 2024

Potential to be First Oral Penem Approved in the U.S.

DUBLIN and CHICAGO, Sept. 10, 2024 (GLOBE NEWSWIRE) -- Iterum Therapeutics plc (NASDAQ:ITRM) (Iterum), a clinical-stage pharmaceutical company focused on developing next-generation oral antibiotics to treat infections caused by multi-drug resistant pathogens in community settings, today announced that a meeting of the U.S. Food and Drug Administration's (FDA) Antimicrobial Drugs Advisory Committee (AMDAC) took place on September 9, 2024 at which Iterum's new drug application (NDA) for sulopenem etzadroxil/probenecid (oral sulopenem) for the treatment of uncomplicated urinary tract infections (uUTI) in adult women was discussed.

Specifically, the FDA convened the AMDAC meeting to discuss a) the overall benefits and risks for the use of sulopenem etzadroxil/probenecid for the treatment of uUTI caused by designated susceptible microorganisms in adult women > 18 years of age, and b) considerations that would be important for medical providers to know to ensure appropriate use of sulopenem etzadroxil/probenecid. The FDA did not ask the AMDAC to vote on any matter.

"We are encouraged by the AMDAC's discussion which acknowledged oral sulopenem as an important treatment option for certain patients with uUTI and agree that the appropriate use of oral sulopenem by treating physicians is critical to limiting antimicrobial resistance," said Corey Fishman, Iterum's Chief Executive Officer. "We look forward to continuing to work with the FDA on the review of the NDA and potential labeling over the next few months."

The AMDAC was provided scientific evidence shared by Iterum, including data from the pivotal REASSURE (REnewed ASsessment of Sulopenem in uUTI caused by Resistant Enterobacterales) Phase 3 clinical trial, and data from the SURE-1 (Sulopenem for Resistant Enterobacteriaceae) Phase 3 clinical trial.

The FDA is not bound by the recommendations of the AMDAC but takes its advice into consideration. The FDA's decision on whether or not to approve oral sulopenem for the treatment of uUTIs in adult women is expected by the Prescription Drug User Fee Act (PDUFA) goal date of October 25, 2024.

About Urinary Tract Infections (UTIs)

UTIs are among the most common bacterial infections encountered in the community. There are approximately 15 million emergency room and office visits for symptoms of UTIs and over 40 million uUTIs treated in the United States annually, with approximately 30% of those infections caused by a quinolone non-susceptible organism, and approximately 1% of those infections caused by pathogens that are resistant to all commonly available classes of oral antibiotics. As a result, the treatment of UTIs has become more challenging because of the development of resistance by pathogens responsible for these infections. uUTIs are infections of the bladder occurring mainly in women. Half (50%) of all women experience at least one uUTI at some point in their lives.
