Outcome Measures
Primary Outcomes (1)
Composite Success at Test of Cure (TOC) in the Microbiological Intent-to-treat (microITT) Population
Microbiologic success is eradication defined as demonstration that any gram-negative bacterial pathogen found at study entry (≥10\^5 CFU/mL) is eradicated to \<10\^3 CFU/mL. Clinical success is defined as symptomatic resolution or return to pre-morbid baseline of all UTI-core symptoms and patient is alive, and patient has not received additional antibacterial therapy for cUTI.
Assessed at Test of Cure visit (occurred once per participant between Study Days 19 to 23)
Secondary Outcomes (49)
Microbiologic Success at Test of Cure (TOC) in the microITT Population
Assessed at Test of Cure visit (occurred once per participant between Study Days 19 to 23)
Clinical Success at Test of Cure (TOC) in the microITT Population
Assessed at Test of Cure visit (occurred once per participant between Study Days 19 to 23)
Composite Success at Test of Cure (TOC) in the Extended Microbiological Intent-to-treat (emicroITT) Population
Assessed at Test of Cure visit (occurred once per participant between Study Days 19 to 23)
Composite Success at End of Treatment (EOT) in the microITT Population
Assessed within 24 hours after last IV dose (up to 15 days from start of treatment)
Microbiological Success at End of Treatment (EOT) in the microITT Population
Assessed within 24 hours after last IV dose (up to 15 days from start of treatment)

Study Arms (2)
Cefepime/VNRX-5133 (taniborbactam)
EXPERIMENTALCefepime/VNRX-5133 administered q8h intravenously (IV) over a 2-hour period.
Meropenem
ACTIVE COMPARATORMeropenem will be administered q8h IV over 30 minutes.
Interventions
Cefepime/VNRX-5133 administered q8h intravenously (IV) over a 2-hour period for 7 days (up to 14 days for patients with bacteremia). Patients will also receive meropenem placebo administered via IV over 30 minutes.
Meropenem will be administered q8h IV over 30 minutes for 7 days (up to 14 days for patients with bacteremia). Patients will also receive cefepime/VNRX-5133 placebo administered via IV over a 2-hour period.
Eligibility Criteria
You may qualify if:
- Adult male and female
- Documented diagnosis of pyuria
- Documented diagnosis of cUTI or Acute Pyelonephritis (AP)
You may not qualify if:
- Receipt of effective antibacterial drug therapy for cUTI for more than 24 hours during the previous 72 hours prior to randomization
- A urine culture result is resistant to meropenem or a gram negative pathogen is not identified or more than 2 microorganisms are isolated or a confirmed fungal UTI is identified
- Required use of nonstudy systemic bacterial therapy
- Suspected or confirmed prostatitis or urinary tract symptoms attributable to sexually transmitted disease
- Patients with perinephric or renal abscess
- Patients with renal transplantation or receiving hemodialysis or peritoneal dialysis
- Abnormal labs
