Primary Outcome Measures
NameTimeMethod
American College of Rheumatology (ACR) 20% response rate4 months (week 16)
Change from baseline in Total Sharp Score (TSS) using the Modified van der Heijde Sharp (vdH-S) method to 6 months (Week 24)Baseline (Day 1), 6 months (Week 24)
Secondary Outcome Measures
NameTimeMethod
Change from baseline in Disease Activity Score-28 (DAS28)-CRP to 4 months (Week16)Baseline (Day 1), 4 months (Week 16)
Safety and tolerability will be measured based on clinical Adverse Events, vital signs, and laboratory abnormalities12 months (Week52)
ACR 70 response rates4 months (Week16)
Non-progressors rate for the structural damageBaseline (Day 1), 6 months (Week 24)

The non-progressors rate is defined as the proportion of subjects meeting the change from baseline in the TSS at 6 months less than or equal to the smallest detectable difference (SDD) and/or the smallest detectable change (SDC)

ACR 50 response rates4 months (Week16)
