Study of Cefepime-zidebactam (FEP-ZID) in Complicated Urinary Tract Infection (cUTI) or Acute Pyelonephritis (AP)

A Phase 3, Randomized, Double-blind, Multicenter, Comparative Study to Determine the Efficacy and Safety of Cefepime-zidebactam vs. Meropenem in the Treatment of Complicated Urinary Tract Infection or Acute Pyelonephritis in Adults

This is a Phase 3, randomized, double-blind, multicenter, non-inferiority study to evaluate the efficacy, safety, and tolerability of FEP-ZID vs. meropenem in the treatment of hospitalized adults with cUTI or AP.

Approximately 528 hospitalized adult subjects (≥ 18 years of age) diagnosed with cUTI or AP will be enrolled in the study. The diagnosis of cUTI or AP will be based on a combination of clinical symptoms and signs plus the presence of pyuria. The total duration of treatment with study drug is 7 to 10 days. Each subject must remain hospitalized during the study drug treatment period; no outpatient parenteral antibiotic therapy is allowed.

Inclusion Criteria:

1. Male or female ≥ 18 years of age
2. Provide a signed written informed consent prior to any study-specific procedures
3. Meet the clinical criteria for either cUTI or AP
4. Requires hospitalization to manage the cUTI or AP
5. Agrees to use effective methods of contraception

Exclusion Criteria:

1. Known or suspected disease that may confound the assessment of efficacy.
2. Receipt of more than 72 hours of prior antibiotic therapy except for those failing prior antibiotic therapy and/or having documented uropathogen resistant to the prior therapy.
3. Rapidly progressive illness such that the subject is unlikely to survive the study period.
4. Pregnant or breastfeeding women
5. History of a seizure disorder requiring current treatment
6. Creatinine clearance < 15 mL/min or on renal dialysis
7. Neutropenia or elevated liver enzymes
8. Hypersensitivity to beta-lactam antibiotics
9. Unlikely to comply with the protocol or the Investigator considers that study participation may not be optimal for the subject
