Pharmacokinetics/Pharmacodynamics (PK/PD) of Multiple Oral Doses of GLPG0555 in Healthy Subjects

This study has been completed.
Information provided by:
Galapagos NV Identifier:
First received: September 23, 2010
Last updated: March 22, 2011
Last verified: March 2011
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.

Condition Intervention Phase
Healthy Drug: GLPG0555 Drug: GLPG0555 aqueous Drug: placebo Phase 1

Study Type: Interventional
Study Design: 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.

Further study details as provided by Galapagos NV:

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

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

Enrollment: 24
Study Start Date: September 2010
