Can a new antibiotic combo beat Drug-Resistant urinary infections in the blood?
NCT ID NCT07725848
First seen Jul 24, 2026 · Last updated Jul 24, 2026
Summary
This study is testing whether a new antibiotic combination, cefepime/enmetazobactam, works as well as the best current treatments for complicated urinary tract infections that have spread to the bloodstream. These infections are caused by bacteria resistant to many common antibiotics. Researchers will compare how quickly the infection clears from the blood in patients receiving the new combination versus standard therapy.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- a new antibiotic combination called cefepime/enmetazobactam (FEP/META)
- What this could lead to
- If effective, this antibiotic combination could offer a new treatment option for hard-to-treat urinary tract infections that have spread to the blood, especially those resistant to multiple drugs.
- What could go wrong
- This is an observational study, not a randomized trial, so results may be less definitive. The antibiotic may not prove superior to existing treatments, and resistance could still develop.

Inclusion Criteria: * Patients with bacteremic cUTIs caused by Gram-negative bacteria treated with FEP/META or BAT * Adult population (age ≥ 18 years) * Signed informed consent form Exclusion Criteria: * Polymicrobial/mixed infections (Gram-positive bacteria or fungi together with Gram-negative microorganisms), except in cases involving multiple Gram-negative bacteria susceptible to the study drugs * Patients with negative blood cultures * Isolation of Gram-negative microorganisms not susceptible to the study drugs (e.g., KPC-producing organisms) * Patients in palliative care or with a high likelihood of death within 72 hours from the index positive blood culture * Patients treated with inappropriate therapy for more than 48 hours * Patients discharged early without follow-up blood cultures * History of significant hypersensitivity or allergic reactions to cefepime, to any of the excipients in the respective formulations, or to beta-lactamase inhibitors (e.g., tazobactam)
