- Change From Baseline in Disease Activity Score Based on 28-Joints Count Using C-reactive Protein [DAS28-3(CRP)] [ Time Frame: Baseline, Week 2, 4, 8 and 12 ]
The DAS28-3 (CRP) score is a measure of the perticipant's disease activity. It is based on the painful and tender joint count (28 joints), swollen joint count (28 joints) and CRP. DAS28-3 (CRP) scores range from 0 - 10; higher scores indicated greater affectation due to disease activity.
Change = value at observation minus value at baseline
- Change From Baseline in Disease Activity Score Based on 28-Joints Count Using Erythrocyte Sedimentation Rate [DAS28-4(ESR)] [ Time Frame: Baseline, Week 2, 4, 8 and 12 ]
The DAS28-4 (ESR) score is a measure of the participant's disease activity. It is based on the painful and tender joint count (28 joints), swollen joint count (28 joints), participant's global assessment of disease activity (mm), and ESR. DAS28-4(ESR) scores range from 0 - 10; higher scores indicated greater affectation due to disease activity.
Change = score at observation minus score at baseline.
- Change From Baseline in Health Assessment Questionnaire-Disability Index (HAQ-DI) [ Time Frame: Baseline, Week 2, 4, 8 and 12 ]
HAQ-DI: participant-reported assessment of ability to perform tasks in 8 categories of daily living activities: dress/groom; arise; eat; walk; reach; grip; hygiene; and common activities over past week. Each item scored on 4-point scale from 0 to 3: 0=no difficulty; 1=some difficulty; 2=much difficulty; 3=unable to do. Overall score was computed as the sum of domain scores and divided by the number of domains answered. Total possible score range 0-3 where 0 = least difficulty and 3 = extreme difficulty.
Change = score at observation minus score at baseline.
- Change From Baseline in Painful and Tender Joint Counts [ Time Frame: Baseline, Weeks 2, 4, 8 and 12 ]
Number of tender joints was determined by examining 68 joints and identified the joints that were painful under pressure or to passive motion. The number of tender joints was recorded on the joint assessment form at each visit, no tenderness = 0, tenderness = 1. A negative value in change from baseline indicates an improvement. Change = value at observation minus value at baseline.
- Change From Baseline in Swollen Joint Count (SJC) [ Time Frame: Baseline, Week 2, 4, 8 and 12 ]
Number of swollen joints was determined by examination of 66 joints and identifying when swelling was present. The number of swollen joints was recorded on the joint assessment form at each visit, no swelling = 0, swelling =1. A negative value in change from baseline indicates an improvement. Change = value at observation minus value at baseline.
- Change From Baseline in Patient's Assessment of Pain [ Time Frame: Baseline, Week 2, 4, 8 and 12 ]
Change from Baseline in Patient's Assessment of Arthritis Pain -VAS (0 to 100 mm visual analog scale, 0 being no pain and 100 being most severe pain) was computed as Week 2, 4, 8 or 12 values minus baseline value. A negative value in change from baseline indicates an improvement.
Change = value at observation minus value at baseline.
- Change From Baseline in Patient's Global Assessment of Arthritis [ Time Frame: Baseline, Week 2, 4, 8 and 12 ]
Participants answered: "Considering all the ways your arthritis affects you, how are you feeling today?" Participants responded by using a 0 - 100 mm Visual Analog Scale where 0 = very well and 100 = very poorly. Change = score at observation minus score at baseline.
- Change From Baseline in Physician's Global Assessment of Arthritis [ Time Frame: Baseline, Week 2, 4, 8 and 12 ]
Physician Global Assessment of Disease Activity was measured on a 0 to 100 mm Visual Analog Scale (VAS), with 0 mm = no disease activity; very good and 100 mm = worst disease activity; very poor. Change = score at observation minus score at baseline.
- Change From Baseline in C- Reactive Protein (CRP) (mg/L) [ Time Frame: Baseline, Week 2, 4, 8 and 12 ]
The test for CRP is a laboratory measurement for evaluation of an acute phase reactant of inflammation through the use of an ultrasensitive assay. A decrease in the level of CRP indicates reduction in inflammation and therefore improvement. Change = value at observation minus value at baseline.
- Area Under Curve (AUC) for Change From Baseline in American College of Rheumatology-N (ACR-N) [ Time Frame: Baseline, Week 12 ]
ACR-N = calculated for each participant by taking lowest percentage improvement in (1) swollen joint count or (2) tender joint count or (3) the median of remaining 5 components of ACR response (participant's assessment of disease activity; participant's global assessment of pain; physician's assessment of disease activity; participant's assessment of physical function; an acute phase reactant value - CRP). Negative numbers indicate worsening. The AUC for ACR-N is measure of the area under the curve of the mean change from baseline in ACR-N. The trapezoidal rule was used to compute AUC.
- Change From Baseline in Euro Quality of Life (EQ-5D) [ Time Frame: Baseline, Week 12 ]
EQ-5D: participant rated questionnaire to assess health-related quality of life in terms of a single utility score. Health State Profile component assesses level of current health for 5 domains: mobility, self-care, usual activities, pain and discomfort, and anxiety and depression; 1 indicates better health state (no problems); 3 indicates worst health state ("confined to bed"). Scoring formula developed by EuroQol Group assigns a utility value for each domain in the profile. Score is transformed and results in a total score range -0.594 to 1.000; higher score indicates a better health state. Change = score at Week 12 minus score at baseline.
