Positive Topline Results for Iterum Therapeutics in Phase 3 UTI Trial

Clinical stage pharmaceutical company, Iterum Therapeutics (Nasdaq: ITRM) has announced positive topline results from its Phase 3 clinical trial comparing oral sulopenem to oral Augmentin® (amoxicillin/clavulanate) in adult women with uncomplicated urinary tract infections (uUTIs).

The study’s results demonstrated that oral sulopenem showed overall success in 61.7% of patients compared to 55.0% for Augmentin®, demonstrating statistically significant superiority of oral sulopenem versus Augmentin®.

Corey Fishman, Iterum’s Chief Executive Officer, commented on the results, “With the positive data from this trial, we plan to resubmit our New Drug Application (NDA) for oral sulopenem for the treatment of uUTI in the second quarter of 2024. At the same time, with these results in hand, we will be focusing on a strategic process to sell, license, or otherwise dispose of our rights to sulopenem with the goal of maximizing value for our stakeholders. We believe there is tremendous value in sulopenem as a potential new, oral antibiotic for the uUTI indication, which has over 30 million infections annually in the U.S., rising resistance to all currently prescribed oral antibiotics, and a complete lack of new product innovation over the last 20 years.”


Iterum’s clinical trial is a Phase 3, randomized, multi-center, double-blind study of the efficacy, tolerability, and safety of oral sulopenem. The trial enrolled 2,222 patients and is being conducted under a Special Protocol Assessment (SPA) agreement with the FDA.

Both oral sulopenem and Augmentin® were well tolerated in the study. No serious adverse events (SAE) were reported in patients receiving oral sulopenem, while five SAEs occurred in patients receiving Augmentin®.

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 30 million uUTIs treated in the United States annually.
