A Randomized, Single Blind, Placebo Controlled Study to Evaluate Safety, Tolerability, and Pharmacokinetics of Single Escalating Oral Doses of GSK2140944 in Healthy Adult Subjects

GSK2140944 belongs to the Bacterial Type II Topoisomerase Inhibitor (BTI) class of antibiotics. GSK2140944 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 is a First Time in Human (FTIH) study to assess the safety, tolerability, and pharmacokinetics of single oral doses of GSK2140944 in healthy volunteers. This study will be a single-blind, randomized, placebo-controlled, dose-rising study in healthy subjects. The proposed single doses will range from 100 mg to 3000 mg.
