GLPG0778: Multiple Ascending Oral Doses, Pharmacokinetic, Safety, and Pharmacodynamic Study
The purpose of the study is to evaluate the safety and tolerability of multiple ascending oral doses (MAD) of GLPG0778 given to healthy subjects for 13 days compared to placebo, and to evaluate the pharmacokinetics (PK) and pharmacodynamics (PD) of GLPG0778 after multiple oral administrations.

- Occurrence of adverse events [ Time Frame: Daily during treatment, up to 10 days postdose ] [ Designated as safety issue: No ]At every study visit, subjects will be asked whether any adverse events have occurred since start of treatment.
- Evaluation of hematological, biochemical and cardiovascular parameters. [ Time Frame: until 10 days postdose. ] [ Designated as safety issue: No ]On predefined timepoints during the study blood and urine samples will be taken, and cardiovascular tests (ECG, blood pressure, heart rate) recorded to assess whether the test compound causes any deviation.
- Pharmacokinetics of repeated doses [ Time Frame: 24 hours postdose ] [ Designated as safety issue: No ]Bloodsamples are taken on various timepoints to assess how much of the study drug is taken up in the blood (absorption), how long it stays in the blood (excretion), and whether any "breakdown"-products of the drug are present (metabolism).
- Pharmacodynamics (PD) of GLPG0778 [ Time Frame: up to 10 days postdose ] [ Designated as safety issue: No ]To explore biomarkers of GLPG0778 activity after repeated oral administrations.
