Primary Outcome Measures:
  • The Number of Participants With Clinical Cure Rate at Test Of Cure (TOC) Visit [ Time Frame: TOC (7 to 14 days after the last dose of study medication therapy) ] [ Designated as safety issue: No ]
    The participants were classified as cure if they had resolution or clinical improvement in signs and symptoms of complicated urinary tract infection; had no fever; no additional antimicrobial therapy was required for the treatment of the infection; and a clinical response assessment of improvement at End of IV visit.


Secondary Outcome Measures:
  • The Number of Participants With Clinical Improvement Rate at End of IV (EIV) Visit [ Time Frame: EIV (within 24 hours after completion of the last dose of IV study medication therapy) ] [ Designated as safety issue: No ]
    The participants were considered as clinical improved if they had clinical improvement in signs and symptoms from baseline; no fever for at least the 24 hours before discontinuing the IV study drug; and not received nonstudy antibiotics for the treatment of urinary tract infection after IV study drug therapy had begun.

  • The Number of Participants With Clinical Cure Rate at Late Follow-Up (LFU) Visit [ Time Frame: LFU (28 to 42 days after the last dose of study medication therapy) ] [ Designated as safety issue: No ]
    The participants were classified as clinical cure if all pretreatment signs and symptoms of complicated urinary tract infection showed no evidence of recurrence after test of cure.

  • The Number of Participants With Favorable Per-participant Microbiological Response [ Time Frame: EIV (within 24 hours after completion of the last dose of IV study medication therapy), TOC (7 to 14 days after the last dose of study medication therapy), and LFU (28 to 42 days after the last dose of study medication therapy) ] [ Designated as safety issue: No ]
    Favorable per-participant microbiological response rate was evaluated at the at End of IV (EIV) visit, Test Of Cure (TOC) visit, and Late Follow-Up (LFU) visit. The favorable per-participant microbiological response was considered when all baseline pathogens were eradicated (absence) or presumed eradicated (absence of material to culture in a participant who has a positive clinical response to treatment).

  • Number of Participants With Favorable Per-pathogen Microbiological Outcome Rate at End of IV (EIV) Visit [ Time Frame: EIV (within 24 hours after completion of the last dose of IV study medication therapy) ] [ Designated as safety issue: No ]
    The favorable per-pathogen microbiological outcome was considered when all baseline pathogens were eradicated (absence) or presumed eradicated (absence of material to culture in a participant who has a positive clinical response to treatment).A total of 4 pathogens in the doripenem group and 2 pathogens in the cefepime group were isolated at baseline from urine culture and were susceptible to the study drug received (see listed in the table below; the numbers in parenthesis next to each pathogen represent the number of participants with the pathogen isolated at baseline in the doripenem and cefepime treatment groups, respectively).

  • Number of Participants With Favorable Per-pathogen Microbiological Outcome Rate at Test Of Cure (TOC) Visit [ Time Frame: TOC (7 to 14 days after the last dose of study medication therapy) ] [ Designated as safety issue: No ]
    The favorable per-pathogen microbiological outcome was considered when all baseline pathogens were eradicated (absence) or presumed eradicated (absence of material to culture in a participant who has a positive clinical response to treatment). A total of 4 pathogens in the doripenem group and 2 pathogens in the cefepime group were isolated at baseline from urine culture and were susceptible to the study drug received (see listed in the table below; the numbers in parenthesis next to each pathogen represent the number of participants with the pathogen isolated at baseline in the doripenem and cefepime treatment groups, respectively).

  • Number of Participants With Sustained Favorable Per-pathogen Microbiological Outcome Rate at Late Follow-Up (LFU) Visit [ Time Frame: LFU (28 to 42 days after the last dose of study medication therapy) ] [ Designated as safety issue: No ]
    The sustained favorable per-pathogen microbiological outcome was considered when all baseline pathogens were eradicated (absence) or presumed eradicated (absence of material to culture in a participant who has a positive clinical response to treatment). A total of 4 pathogens in the doripenem group and 2 pathogens in the cefepime group were isolated at baseline from urine culture and were susceptible to the study drug received (see listed in the table below; the numbers in parenthesis next to each pathogen represent the number of participants with the pathogen isolated at baseline in the doripenem and cefepime treatment groups, respectively).

Detailed Description:

This is a randomized (study assigned by chance), double-blind (neither physician nor patient knows the name of the assigned study drugs), double-dummy (all patients are given both a placebo [salt solution] and study drug in alternating periods of time during the study), active comparator-controlled (compare the 'test' treatment to standard-of-care therapy), multinational, multicenter study to establish the safety and tolerability of the antibiotic doripenem compared with the antibiotic cefepime administered by intravenous (iv) infusion (slow injection of drug solution into the vein over a period of time) in children ages 3 months to less than 18 years hospitalized with a complicated urinary tract infection (cUTI). The study includes 3 periods: a pretreatment (screening) period that will occur within 2 days prior to randomization (assignment of study drug); a treatment period of 10 to 14 days where the patients will receive study drug treatment, and a posttreatment period consisting of 2 study visits. The maximum duration of study drug therapy is 14 days. The total duration of the study is approximately 7 to 8 weeks for each patient. Safety and tolerability will be evaluated by examining the incidence, severity, and type of adverse events, changes in clinical laboratory tests, vital sign measurements, and findings from physical examinations that are recorded as adverse events during treatment and at each posttreatment visit. An independent monitoring committee (IDMC) will be established for this study to ensure that the safety of patients is not compromised. The IDMC will consist of individuals who are not associated with the conduct of the study, and will include but will not be limited to individuals with expertise relevant to the care of pediatric patients, and including at least one infectious disease physician and at least one statistician. IV study drug therapy (Cefepime [50mg/kg up to 2g/dose] and doripenem placebo or doripenem [20mg/kg up to 500mg/dose] and cefepime placebo will be administered once every 8 hours for up to 14 days. After receiving a minimum of 3 days of IV study drug therapy, patients may be discharged from the hospital and continue PO antibiotic therapy with amoxicillin/clavulanate potassium, ciprofloxacin, or alternative antibiotic therapy.
