Safety and Efficacy of IV CXA-101 and IV Ceftazidime in Patients With Complicated Urinary Tract Infections

Phase 2
Completed
Conditions
Complicated Urinary Tract Infection
Interventions
Registration Number
NCT00921024
Lead Sponsor
Cubist Pharmaceuticals LLC, a subsidiary of Merck & Co., Inc. (Rahway, New Jersey USA)
Brief Summary

The purpose of this study is to evaluate the safety and efficacy of intravenous CXA 101 and comparator in complicated urinary tract infection

Detailed Description

This is a Phase 2, multicenter, prospective, randomized, double-blind, comparative efficacy and safety study of IV CXA 101 versus IV ceftazidime for 7 to 10 days.

Subjects are followed up 6 to 9 days after the last dose of study drug to assess clinical signs and symptoms of infection. A Late Follow Up evaluation (21 to 28 days after the last dose of study drug) occurs for those subjects who respond to therapy. The primary assessment of effectiveness is the microbiological response (the eradication at post-therapy of the infectious organism identified at the start of study). An additional assessment of efficacy includes the overall clinical response, which is described as cured, improved, or failed. Safety assessments include the incidence of adverse events throughout the study, clinical laboratory tests (hematology, serum chemistry, and urinalysis) and physical examinations at the start of the study and post-therapy.
