Dose-finding Study of GLPG0634 as add-on to Methotrexate in Active Rheumatoid Arthritis Participants (DARWIN1) — DARWIN1  

Rheumatoid Arthritis Clinical Trial

Official title: Randomized, Double-blind, Placebo-controlled, Multicenter, Phase IIb Dose Finding Study of GLPG0634 Administered for 24 Weeks in Combination With Methotrexate to Subjects With Moderately to Severely Active Rheumatoid Arthritis Who Have an Inadequate Response to Methotrexate Alone

Status Completed

Clinical Trial Summary

Participants suffering from active rheumatoid arthritis despite continued treatment with methotrexate were evaluated for improvement of disease activity (efficacy) when taking GLPG0634 (3 different doses - 50 milligram [mg], 100 mg and 200 mg daily -, each evaluated as once daily [QD] and twice daily [BID] regimen) or matching placebo for 24 weeks.

•During the course of the study, patients were also examined for any side effects that could occur (safety and tolerability), and the amount of GLPG0634 present in the blood (Pharmacokinetics) as well as the effects of GLPG0634 on disease- and mechanism of action-related parameters in the blood (Pharmacodynamics) were determined. Also, the effects of different doses and dose regiments of GLPG0634 administration on participants' disability, fatigue, and quality of life were evaluated.

Clinical Trial Description

• Treatment duration was 24 weeks in total.

• However, at Week 12, participants on placebo who did not achieve a 20% improvement in swollen joint count(SJC66) and tender joint count (TJC68) were re-randomized (automatically via interactive voice/web response [IXRS]) to treatment to receive GLPG0634 100 mg QD or 50 mg BID doses in a blinded fashion, participants on 50 mg QD who had not achieved a 20% improvement in SJC66 and TJC68 were assigned to 100 mg QD and participants on 25 mg BID. who did not achieve a 20% improvement in SJC66 and TJC68 were assigned to 50 mg BID. All continued the study until Week 24.

• Participants in the other groups maintained their randomized treatment until Week 24. ;
