Disease Activity Score Based on 28-Joints Count (DAS28) Using C-Reactive Protein (CRP) |
DAS28 (CRP) was calculated from number of swollen joints and tender joints using the 28 joints count; CRP (milligram/Liter [mg/L]); and general health visual analog scale (VAS) score (participant rated scale with scores ranging from 0mm [very well] to 100mm [extremely bad]). Total score range: 0 to 9.4, higher score indicated more disease activity. DAS28 (CRP) less than or equal to (<=) 3.2 implied low disease activity, greater than (>) 3.2 to 5.1 implied moderate to high disease activity, and less than (<) 2.6 implied remission. |
Baseline, Week 2, 4, 6, 8, 10, 12 |
|
| Secondary |
Disease Activity Score Based on 28-Joints Count (DAS28) Using Erythrocyte Sedimentation Rate (ESR) |
DAS28 (ESR) was calculated from the number of swollen joints and tender joints using the 28 joints count; ESR (millimeters per hour [mm/hour]); and general health VAS score (participant rated scale with scores ranging from 0 [very well] to 100 [extremely bad]). Total score range: 0 to 9.4, higher score indicated more disease activity. DAS28 (ESR) <=3.2 implied low disease activity, >3.2 to 5.1 implied moderate to high disease activity, and <2.6 implied remission. |
Baseline, Week 2, 4, 6, 8, 10, 12 |

| Secondary |
Tender Joints Counts (TJC) |
Number of tender joints was determined by examining 28 joints and identified the joints that were painful under pressure or to passive motion. |
Baseline, Week 2, 4, 6, 8, 10, 12 |
|
| Secondary |
Swollen Joints Count (SJC) |
Number of swollen joints was determined by examination of 28 joints and identifying when swelling was present. |
Baseline, Week 2, 4, 6, 8, 10, 12 |

Physician Global Assessment of Disease Activity |
Physician global assessment of disease activity was measured on an 11-point scale, ranging from 0 to 10, where 0 = no disease activity and 10 = extreme disease activity. |
Baseline, Week 2, 4, 6, 8, 10, 12 |
|
| Secondary |
Participant Global Assessment of Disease Activity |
Participants answered: "considering all the ways your arthritis affects you, how are you feeling today?" Participants responded by using a scale ranging from 0 to 10, where 0 = no disease activity and 10 = extreme disease activity. |
Baseline, Week 2, 4, 6, 8, 10, 12 |

Pain Visual Analog Scale (VAS) |
Participants assessed the amount of pain currently experienced by them on a 100 millimeter (mm) VAS ranging from 0= no pain to 100= severe pain. |
Baseline, Week 2, 4, 6, 8, 10, 12 |
|
| Secondary |
General Health Visual Analog Scale (VAS) |
General health VAS is a 100 mm line marked by the participant. Participants were asked, "In general how would you rate your health currently concerning the arthritis?" Scores ranged from 0 mm = very well to 100 mm = extremely bad. |
Baseline, Week 2, 4, 6, 8, 10, 12 |

Health Assessment Questionnaire-Disability Index (HAQ-DI) Score |
Health assessment questionnaire-disability index (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 perform activity. 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. |

36-Item Short-Form Health Survey (SF-36) |
SF-36 is a standardized survey consisting of 36 items summarized into 8 multi-item scales evaluating 8 aspects of functional health and well-being: physical and social functioning, physical and emotional role limitations, bodily pain, general health, vitality and mental health. Two summary scores, the physical component summary (PCS) and the mental component summary (MCS) derived are derived by aggregating the 8 aspects. The score for each aspect and physical and mental component summary are scaled 0-100 where, higher score indicating highest level of functioning. |

Functional Assessment of Chronic Illness Therapy (FACIT)-Fatigue Scale |
FACIT-fatigue is a 13-item questionnaire. Participants score each item on a 5-point scale ranging from 0 (not at all) to 4 (very much). The scoring algorithm is such that the item responses are reversed in score (except for 2 items, "I have energy" and "I am able to do my usual activities"), in order to reflect higher scores as less fatigue. The sum of all responses resulted in the FACIT-fatigue total score for a total possible score of 0 (worse score) to 52 (better score). A higher score reflected an improvement in the participant's health status. |

Number of Participants With European League Against Rheumatism (EULAR) Response Based on DAS28 |
DAS28-based EULAR response criteria was used to measure individual response as none, good and moderate, depending on the extent of change from baseline and the level of disease activity reached. Good responders: change from baseline >1.2 with DAS28 =< 3.2; moderate responders: change from baseline >1.2 with DAS28 >3.2 to =<5.1 or change from baseline >0.6 to =<1.2 with DAS28 =<5.1; non-responders: change from baseline =< 0.6 or change from baseline >0.6 and =<1.2 with DAS28 >5.1. |
