First received: August 14, 2012
Last updated: June 26, 2013
Last verified: June 2013
  • Ninety patients suffering from active rheumatoid arthritis despite continued treatment with methotrexate will be evaluated for improvement of disease activity when taking GLPG0634 (4 different doses will be evaluated) or matching placebo for 4 weeks.
  • During the course of the study, patients will also be examined for any side effects that may occur, and the amount of GLPG0634 present in the blood as well as the effects of GLPG0634 on disease- and mechanism of action-related parameters in the blood will be determined.

Condition Intervention Phase
Rheumatoid Arthritis
Drug: GLPG0634
Drug: Placebo
Phase 2

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double Blind (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: Randomized, Double-blind, Placebo-controlled, Multicenter, Phase II Study to Compare Four Dose Regimens of GLPG0634 Versus Placebo, in Combination With Methotrexate, Administered for 4 Weeks in the Treatment of Subjects With Active Rheumatoid Arthritis Who Have an Inadequate Response to Methotrexate Alone

Further study details as provided by Galapagos NV:

Primary Outcome Measures:
  • The number of patients with an ACR20 score at Week 4 as a measure of efficacy [ Time Frame: Week 4 (end of treatment visit) ]
    To preliminary evaluate the efficacy of GLPG0634 compared to placebo in terms of the proportion of subjects achieving an ACR20 response at Week 4

Secondary Outcome Measures:
  • The number of patients with ACR20/50/70 response, time to response and DAS28 score at every visit as a measure of efficacy [ Time Frame: From Day -1 up to end of treatment visit (week 4) ]
    To evaluate the efficacy of GLPG0634 compared to placebo in terms of ACR response criteria at every visit (ACR20, ACR50, ACR70), time to response, and disease status (DAS28[C-reactive protein, CRP]

  • The number of patients with adverse events, abnormal lab tests, vital signs and ECG as a measure of safety and tolerability [ Time Frame: From screening up to 10 days after last dose ]
    To evaluate the safety and tolerability of GLPG0634 in comparison with placebo in terms of adverse events (AEs), laboratory test abnormalities, vital signs and electrocardiogram (ECG)

  • The plasma levels of GLPG0634 as a measure of PK [ Time Frame: Week 1, week 2 and week 4 visits ]
    To characterize the pharmacokinetics (PK) of GLPG0634 by measuring the amount of GLPG0634 in the plasma

  • The plasma levels of GLPG0634 and MTX as a measure of PK [ Time Frame: Day -1 and Week 2 or 4 visit (8 hour-sampling) ]
    To explore the potential interaction of GLPG0634 on MTX by assessing steady state PK in an 8-hour sampling at Day -1 and at Week 2 or Week 4 visit in a subset of patients

  • The levels of immune- and inflammation-related parameters in plasma as a measure of PD [ Time Frame: Day -1, Week 1, week 2 and week 4 visits ]
    To characterize the pharmacodynamics (PD) of GLPG0634 by measuring the levels of immune- and inflammation-related parameters in plasma
