A Study to Evaluate How Well Single and Multiple Doses of GLPG3121-modified Release Formulation Are Tolerated in Healthy, Adult Subjects

The aim of the study is to examine the safety and tolerability of GLPG3121-modified release formulation when given to healthy male subjects once as a single dose or multiple times over a period of 14 days in fasting condition or after a standard breakfast. The study will evaluate how the body absorbs and breaks down GLPG3121, and how GLPG3121 and the major breakdown product of GLPG3121 are eliminated from the body. In addition, the study will investigate the effect of food (high-fat) after a single oral dose of GLPG3121 as modified release tablet.
