Trial overview
Official title: A randomised, double-blind, dose-finding, multicenter study of the safety, tolerability, and efficacy of GSK2251052 therapy compared to imipenem-cilastatin in the treatment of adult subjects with febrile complicated lower urinary tract infections and acute pyelonephritis
Trial description: This study is being conducted to evaluate the safety, efficacy (clinical and microbiological), pharmacokinetics/pharmacodynamics of GSK2251052 and to assess whether it would be a suitable antibiotic for the treatment for febrile lower cUTI and pyelonephritis(complicated and uncomplicated). GSK2251052 will be compared to imipenem-cilastatin, which is an antibiotic commonly used to treat serious cUTI infections. GSK2251052 has a spectrum of microbiological activity that includes pathogens responsible for cUTI.
