  2. ACR20 is 20% improvement according to American College of Rheumatology criteria. Subjects will be considered an ACR20 responder if : compared to Baseline (Day 0), they achieve : 20% decrease in swollen joint count, 20% decrease in tender joint count, and 20% improvement in 3 of the following 5 measures: 1) CRP 2) Health Assessment Questionnaire – Disability Index 3) Subject’s pain assessment 4) Subject’s Global Assessment 5) Physician’s Global Assessment.
