Summary

GSK945237 belongs to the Bacterial Type II Topoisomerase Inhibitor (BTI) class of antibiotics. GSK945237 has demonstrated in vitro and in vivo activity against Gram positive \[including methicillin resistant Staphylococcus aureus (MRSA)\] and Gram-negative pathogens associated with respiratory tract, skin and soft tissue infections including isolates resistant to existing classes of antimicrobials. This study will be conducted in four (4) parts, with a single oral dose being explored in Part A (2400 mg) and repeat oral doses (b.i.d. and q.d.) being explored in Part B. Parts C and D will be optional evaluations of repeat oral doses of linezolid and a comparative evaluation of the effect of GSK945237 and moxifloxacin, respectively. Parts A and B will be single-blind, randomized, placebo-controlled, dose-rising (Part B only) studies of healthy subjects to evaluate the safety, tolerability and pharmacokinetics of GSK945237. The proposed doses range from 400 mg to 2400 mg. Part C will be a single-blind, randomized, and placebo-controlled repeat dose evaluation of 600 mg (b.i.d.) of linezolid. Part D will be a single-blind, randomized, placebo-controlled, two period crossover study. The proposed doses for Part D will be 1200 mg GSK945237 and 400 mg moxifloxacin.
