Oral Bioavailability of Solid Formulation of GLPG1837 With and Without Food

An Open-label Study to Compare the Oral Bioavailability of an Oral Tablet of GLPG1837 Relative to an Oral Suspension After Single-dose Intake in Healthy Subjects and to Evaluate the Effect of Food on the Oral Tablet

The purpose of the study is to evaluate the amount of GLPG1837 and metabolite present in the blood (relative bioavailability) after a single oral administration of 500 mg GLPG1837 given as an oral suspension under fasted conditions as well as a tablet formulation under fasted and fed conditions, in male healthy subjects.

Also, the safety and tolerability of a single oral dose of 500 mg GLPG1837 given as an oral suspension under fasted conditions as well as a tablet formulation under fasted and fed conditions, will be assessed.

Twelve subjects will receive GLPG1837 on 3 occasions as single dose administrations: as an oral suspension fasted, as an oral tablet, fed and fasted. Treatment administrations will be separated by a wash-out period of at least 6 days.
