Further study details as provided by AstraZeneca:

Primary Outcome Measures:
  • Estimate the by-patient microbiological response of NXL104/ceftazidime in the treatment of adult patients with complicated urinary tract infections (cUTI) [ Time Frame: 5 to 9 days post-therapy ] [ Designated as safety issue: No ]
  • Evaluate the safety and tolerability profile [ Time Frame: Treatment plus 14 days ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • Estimate the clinical outcome of NXL104/ceftazidime [ Time Frame: End of IV therapy, Test of Cure visit 5 to 9 days post-therapy and late follow-up visit ] [ Designated as safety issue: No ]
  • Estimate the by-pathogen microbiological response [ Time Frame: End of IV therapy, the Test of Cure visit 5 to 9 days post-therapy and at the late follow-up visit ] [ Designated as safety issue: No ]
