Proportion of subjects achieving American College of Rheumatology 50% (ACR50) Response
Délai: Week 24
|
ACR50 response: greater than or equal to (>=) 50 percent (%) improvement in painful and tender joint count; >= 50% improvement in swollen joint count; and >= 50% improvement in at least 3 of 5 remaining ACR core measures: patient assessment of pain; patient global assessment of disease activity; physician global assessment of disease activity; self-assessed disability (disability index of the Health Assessment Questionnaire [HAQ]); and C-Reactive Protein (CRP)at each visit. |

Proportion of subjects achieving DAS28-hsCRP <2.6
Délai: Week 24
|
Disease Activity Score (DAS) based on a 28 joint count hsCRP consisted of composite numerical score of following variables: tender joint count (TJC28), swollen joint count (SJC28), hsCRP (mg/mL), and patient's global assessment of disease activity. DAS28-hsCRP was calculated using following formula: DAS28-hsCRP equals to (=) 0.56*square root (sqrt) (TJC28) plus (+) 0.28*sqrt (SJC28) + 0.36*natural log(hsCRP+1) + 0.014*participant's global assessment of disease activity + 0.96. Scores ranged 0-9.4, where lower scores indicated less disease activity. |

Proportion of subjects achieving American College of Rheumatology 20% (ACR20) and 70% (ACR70) Response
Délai: Week 24

ACR20/70 response: greater than or equal to (>=) 20/70 percent (%) improvement in painful and tender joint count; >= 20%/70% improvement in swollen joint count; and >= 20%/70% improvement in at least 3 of 5 remaining ACR core measures: patient assessment of pain; patient global assessment of disease activity; physician global assessment of disease activity; self-assessed disability (disability index of the Health Assessment Questionnaire [HAQ]); and C-Reactive Protein (CRP)at each visit. |

Disease Activity Score (DAS) based on a 28 joint count hsCRP consisted of composite numerical score of following variables: tender joint count (TJC28), swollen joint count (SJC28), hsCRP (mg/mL), and patient's global assessment of disease activity. DAS28-hsCRP was calculated using following formula: DAS28-hsCRP equals to (=) 0.56*square root (sqrt) (TJC28) plus (+) 0.28*sqrt (SJC28) + 0.36*natural log(hsCRP+1) + 0.014*participant's global assessment of disease activity + 0.96. Scores ranged 0-9.4, where lower scores indicated less disease activity. Change = value at observation minus value at baseline. |

Changes From Baseline in Health Assessment Questionnaire-Disability Index (HAQ-DI) Total Score
Délai: Week 24
|
HAQ-DI score was an evaluation of the functional status for a participant. The 20-question instrument assessed the degree of difficulty a person had in accomplishing tasks in 8 functional areas (dressing, arising, eating, walking, hygiene, reaching, gripping, and activities of daily living). Responses in each functional area were scored from 0, indicated no difficulty, to 3, indicated inability to perform a task in that area. 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. |

Changes From Baseline in SF-36 Score
Délai: Week 24
|
SF-36 score was an evaluation of the functional status for a participant,taping eight health concepts: physical functioning, bodily pain, role limitations due to physical health problems, role limitations due to personal or emotional problems, emotional well-being, social functioning, energy/fatigue, and general health perceptions. Coded numeric values are recoded per the scoring key. All items are scored so that a high score defines a more favorable health state. Each item is scored on a o to 100 range. Items in the same scale are averaged together to create the 8 scale scores. |
