Dose-ranging Study With GLPG0634 in Methotrexate-refractory Active Rheumatoid Arthritis Patients
- Registration Number
- NCT01668641
- Lead Sponsor
- Galapagos NV
- Brief Summary
* 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.

- Primary Outcome Measures
Name Time Method The number of patients with an ACR20 score at Week 4 as a measure of efficacy 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
Name Time Method The number of patients with ACR20/50/70 response, time to response and DAS28 score at every visit as a measure of efficacy 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 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 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 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 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
