Brief Summary:
The purpose of the study is to evaluate the safety and tolerability of multiple ascending oral doses (MAD) of GLPG0555 given to healthy subjects for 13 days compared to placebo, and to evaluate the relative bioavailability and pharmacokinetics (PK) of two different aqueous suspensions of GLPG0555 administered for 3 days. Finally, it is aimed to characterize PK and pharmacodynamics (PD) of GLPG0555 after multiple oral administrations.

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 24 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Official Title: Double Blind Placebo Controlled Dose Ranging Study for the Assessment of Safety, Tolerability, Pharmacokinetics, and Pharmacodynamics of Multiple Oral Doses of GLPG0555 in Healthy Subjects.
Study Start Date : September 2010
Actual Primary Completion Date : November 2010
Actual Study Completion Date : February 2011

Arm Intervention/treatment
Experimental: Aqueous formulations for formulation selection
50 mg once daily for 3 days of two different aqueous suspensions, with four day wash-out between formulation
Drug: GLPG0555
two different aqueous formulations

Experimental: GLPG0555 ascending doses
multiple ascending doses for 13 days, ranging from 100 mg once daily upto a maximum to be determined during escalation (given as once or twice daily)
Drug: GLPG0555 aqueous
multiple dose, aqueous formulation, 13 days, 100 mg/day once daily, maximum dose to be determined

Placebo Comparator: 3
once or twice daily for 13 days, matching the scheme of the multiple ascending dose.
Drug: placebo
multiple dose, aqueous formulation, 13 days days, matching ascending dose schedule

Primary Outcome Measures :
  1. Safety and tolerability of multiple dosing [ Time Frame: Daily during treatment, up to 10 days postdose ]

Secondary Outcome Measures :
  1. Pharmacokinetics of repeated doses [ Time Frame: 24 hours postdose ]
  2. Pharmacodynamics (PD) of GLPG0555 after repeated oral administration [ Time Frame: up to 10 days postdose ]
  3. The relative bioavailability and pharmacokinetics (PK) of two different aqueous suspensions administered for three days [ Time Frame: up to 24 hours postdose ]
