Dose-finding Study of GLPG0634 as Monotherapy in Active Rheumatoid Arthritis (RA) Participants (DARWIN2)

• Status: Completed
• Trial end date: 2015-05-29
• Target enrollment: 0
• Participant gender: All

Summary

• Participants suffering from active rheumatoid arthritis who had an inadequate response to methotrexate were evaluated for improvement of disease activity (efficacy) when taking GLPG0634 as monotherapy (3 different doses - 50 milligram (mg), 100 mg and 200 mg once daily) 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 of GLPG0634 administration on participants' disability, fatigue and quality of life were evaluated.

• Phase: Phase 2

Criteria

Inclusion Criteria:

• male or female subjects who are ≥18 years of age on the day of signing informed consent,

• have a diagnosis of RA since at least 6 months and meeting the 2010 ACR/EULAR criteria of RA and ACR functional class I-III,

• have ≥6 swollen joints (from a 66-joint count) and

≥8 tender joints (from a 68-joint count) at Screening and at Baseline,

• Screening serum c-reactive protein ≥ 0.7 x upper limit of laboratory normal range (ULN),

• have shown an inadequate response in terms of either lack of efficacy or toxicity to MTX,

• have agreed to be washed out from MTX for a period of at least 4 weeks before or during the Screening period.

Exclusion Criteria:

• current therapy with any non-biological disease modifying anti-rheumatic drug (DMARD), with the exception of antimalarials, which must be at a stable dose for at least 12 weeks prior to Screening,

• current or previous RA treatment with a biologic DMARD, with the exception of biologic DMARDs: administered in a single clinical study setting, and; more than 6 months prior to Screening (12 months for rituximab or other B cell depleting agents), and; where the biologic DMARD was effective, and if discontinued, this should not be due to lack of efficacy,

• previous treatment at any time with a cytotoxic agent, other than MTX, before Screening.
