Study to Compare Bioavailability of GLPG1972 Given as 2 Different Tablet Formulations Versus an Oral Solution

Study Overview
=================
Brief Summary
-----------------
This study is a Phase I, randomized, open-label, cross-over study with 4 single-dose treatments of GLPG1972 to compare the bioavailability of the oral wet granulation (WG) tablet relative to an oral solution and to the oral direct compression (DC) tablet after single dose intake in healthy male subjects and to evaluate the effect of food on the bioavailability of the WG oral tablet.
