  • Microbiological response by baseline isolate for the ME and m-mITT populations [ Time Frame: 14-21 days after last dose of therapy ] [ Designated as safety issue: No ]

Estimated Enrollment: 470
Study Start Date: November 2012
Estimated Study Completion Date: August 2016
Estimated Primary Completion Date: July 2016 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Group A Drug: Tigecycline
every 12 hours (an initial intravenous dose of 100 mg followed by 50 mg twice a day approximately every 12 hours) and placebo intravenous doses every 12 hours beginning 6 hours after the initial intravenous dose of tigecycline for at least for 5 days and up to 14 days.
Active Comparator: Group B Drug: Imipenem/cilastatin
every 6 hours intravenously, and the imipenem/cilastatin will be dosed by 500mg/500mg for the subjects with creatinine clearance equal or above 71ml/min/1.73m2 or dose will be adjusted by Schedule of Study Drug Administration for Subjects with Renal Impairment.
