Eligible subjects will be randomized to receive GSK101892 and placebo. Subjects will receive escalated doses of GSK101892 with a starting dose of 0.5 milligrams. Each subject will receive no more than 4 doses of GSK1018921 in a maximum of 5 dosing sessions. Within each cohort, each session will be separated by a washout period of at least 7 days.
