A Clinical Trial to Find Out V81444's Side Effects and Blood Levels in Healthy Men

Study Overview
=================
Brief Summary
-----------------
A double-blind, randomised, placebo-controlled study of the safety, tolerability and pharmacokinetics of single and multiple ascending oral doses of V81444 in healthy male volunteers

Detailed Description
-----------------
Part A - Single Ascending Dose (SAD) Double-blind, randomised, placebo-controlled, single ascending dose study. Each study subject will participate in a screen visit, three identical treatment periods, in each of which they will receive a single oral dose of V81444 or placebo in accord-ance with the randomisation schedule, and one post-study visit. In each treatment period, subjects will be admitted the day before dosing (Day -1) and, subject to satisfactory medical review, discharged in the morning, 4 days later (Day 4). Part B - Multiple Ascending Dose (MAD) Double-blind, randomised, placebo-controlled, parallel group, multiple ascending dose study Each study subject will participate in a screen visit, one treatment period in which they will receive repeated oral doses of V81444 or placebo in accordance with the randomisation schedule, and one post-study visit. In each treatment period, subjects will be admitted the day before dosing (Day -1), dosed daily on Days 1 to 14 and, subject to satisfactory medical review, will be discharged in the morning, 3 days after the final dose (Day 17).
