Clinical Trial Summary

The purpose of this study is to evaluate the safety, tolerability, and pharmacokinetics of intravenous sulopenem and oral sulopenem etzadroxil/probenecid in adolescent patients.

Description:

After being informed about the study and potential risks, all patients giving written informed consent will be screened for eligibility. Hospitalized patients who are 12-18 years of age and who are receiving background antibiotic treatment for uncomplicated urinary tract infection, complicated urinary tract infection, acute pyelonephritis, or complicated intraabdominal infection, and who meet eligibility requirements will receive a single 1000 mg IV dose of sulopenem on Day 1. The following day, patients will receive a single dose of 500 mg of sulopenem etzadroxil and 500 mg of probenecid given orally as a bilayer tablet. During treatment, pharmacokinetic samples will be collected and patients will be monitored for safety and tolerability.

13. Patient has participated in any other clinical study where an investigational product was ingested within 30 days or 5 half-lives of the drug (whichever is longer) prior to the current study.

14. Patient has definite or suspected personal history or family history of clinically significant adverse drug reactions.

15. Patient has history or presence of GI, hepatic, or renal disease, or other conditions known to interfere with absorption, distribution, metabolism, or excretion of drugs.

16. Patient had treatment in the previous 3 months with any drug known to have a well-defined potential for hepatotoxicity (eg, halothane).
