In phase III SURE 1 trial sulopenem meets endpoint for uncomplicated urinary tract infections.- Iterum Therapeutics

Iterum Therapeutics announced topline results from its phase III SURE 1 clinical trial of sulopenem for the treatment of Uncomplicated Urinary Tract Infections (uUTI). Sulopenem is a novel anti-infective compound that, if approved, would be the first penem antibiotic with an oral formulation indicated for treatment of uUTI.

In SURE1, there were two independent primary endpoints, with achievement of either of those endpoints expected to provide a potential path to marketing approval based on previous discussions with the FDA. In the population of patients with baseline pathogens resistant to quinolones, sulopenem achieved the related primary endpoint by demonstrating superiority to ciprofloxacin, providing substantial evidence of a treatment effect in patients with uUTI. With a p-value of <0.001, this result was highly statistically significant.

In the second population of patients with organisms susceptible to quinolones, sulopenem was not non-inferior to ciprofloxacin and did not achieve the related primary endpoint, with the difference in outcomes driven by the rate of asymptomatic bacteriuria post treatment. In SURE1, sulopenem was well tolerated with a favorable safety profile, consistent with the SURE2 and SURE3 trials.
