Sulopenem etzadroxil/probenecid is available to clinicians through an Expanded Access Program for the treatment of complicated urinary tract infections due to quinolone nonsusceptible uropathogens after an initial course of effective intravenous therapy. The investigational product may be requested by sending an email to the Sponsor (EAProgram@iterumtx.com), as listed on the Reagan Udall EAP Navigator website (https://navigator.reaganudall.org/company-directory/i).

This Expanded Access Program will allow clinicians to use sulopenem etzadroxil/probenecid for the treatment of patients with serious or immediately life-threatening complicated urinary tract infection due to quinolone-nonsusceptible uropathogens where there are no satisfactory oral alternatives to use as step-down therapy after receiving an initial course of effective intravenous therapy. The recommended dose of sulopenem etzadroxil/probenecid 500 mg/ 500 mg is one bilayer tablet orally twice daily, taken with food whenever possible. No dose adjustment is required for patients with renal impairment. Duration of therapy will be at the discretion of the prescribing clinician, depending on the type of infection being treated and the response to therapy, and is expected to be less than ten days total.
