E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective of the study is to evaluate the efficacy in terms of the percentage of subjects achieving an ACR20 response, of different doses of GLPG0634 given once daily compared with placebo at Week 12. |
|
E.2.2 | Secondary objectives of the trial |
The secondary objectives of the study are:
• To evaluate the efficacy in terms of the percentage of subjects achieving an ACR20, ACR50, ACR70, ACR N, DAS28(CRP), EULAR response and ACR/EULAR remission, CDAI, and SDAI with different doses of GLPG0634 given once daily compared with placebo at every visit.
• To evaluate the safety and tolerability of different doses of GLPG0634 in comparison with placebo.
• To characterize the population PK and PD of GLPG0634 and its metabolite (G254445) in subjects with rheumatoid arthritis and investigate the relationship between exposure and efficacy/safety/PD.
• To evaluate the effects of different doses of GLPG0634 administration on subjects’ disability, fatigue, and quality of life.

E.3 | Principal inclusion criteria |
To be eligible for study entry subjects must fulfil all of the following
criteria:
4. Screening serum CRP ≥ 0.7 x upper limit of the normal (reference)
laboratory range (ULN).
5. Have shown an inadequate response in terms of either lack of efficacy
or toxicity to MTX.
6. Have agreed to be washed out from MTX for a period of at least 4
weeks before or during the Screening period.

7. If taking oral steroids, these should be at a dose ≤10 mg/day of
prednisone or prednisone equivalent and stable for at least 4 weeks
prior to Baseline.
8. If taking non-steroidal anti-inflammatory drugs (NSAIDs), these must
be at a stable dose for at least 2 weeks prior toBaseline.
9. The results of the following laboratory tests performed at the central
laboratory at Screening must be within the limits specified below:
a) Hemoglobin ≥10 g/d (International System of Units [SI]: ≥100 g/L);
b) WBCs ≥3.0 x 103 cells/mm3 (SI: ≥3.0 x 109 cells/L);
c) Neutrophils ≥2.0 x 103 cells/mm3 (SI: ≥2.0 x 109 cells/L);
d) Lymphocytes ≥1.0 x 103 cells/mm3 (SI: ≥1.0 x 109 cells/L);
e) Platelets ≥100 x 103 cells/mm3 (SI: ≥100 x 109 cells/L);
f) Serum ALT and aspartate aminotransferase (AST) ≤1.5 x ULN;
g) Total bilirubin level ≤1.25 x ULN;
h) Alkaline phosphatase ≤1.5ULN;
i) Lipase ≤1.5 x ULN and amylase ≤1.5 x ULN;
j) Creatinine clearance >60 mL/min. Creatinine clearance will be
calculated using the Cockroft-Gault formula.

E.4 | Principal exclusion criteria |
applicable:
Current therapy with any non-biological DMARD, including oral or
injectable gold, sulfasalazine, azathioprine, or D penicillamine within 4
weeks prior to Baseline,
cyclosporine within 8 weeks prior to Baseline, and leflunomide within 3
months prior to Baseline or a minimum 4 weeks prior to Baseline if after
11 calendar days of standard cholestyramine therapy, with the exception
of antimalarials, which must be at a stable dose for at least 12 weeks
prior to Baseline.
3. 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.
4. Previous treatment at any time with a cytotoxic agent, other than
MTX, before Screening. These agents include, but are not limited to
chlorambucil, cyclophosphamide, nitrogen mustard, or other alkylating
agents.
