New antibiotic combo shows promise against tough UTIs
NCT ID NCT04979806
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested a new antibiotic combination, cefepime-zidebactam, against a standard antibiotic (meropenem) in adults hospitalized with complicated urinary tract infections or kidney infections. About 530 participants received either the new drug or the standard one for 7 to 10 days. The goal was to see if the new antibiotic works as well and is safe. This is a late-stage trial (Phase 3) that has already been completed.
