Secondary
| Measure | Time frame | Description |
|---|---|---|
| Disease Activity Score (DAS28) of Parts 2 and 3 Participants | Day 43 | The DAS28 is a composite score based on tender and swollen joint counts, C reactive protein (CRP) concentrations, and the participant's global disease activity based on a visual analogue scale (VAS). The tender joint count (based on 28 joints) was calculated by scoring several different aspects of tenderness as assessed by pressure and joint manipulation on physical examination. The information on various types of tenderness was then collapsed into a single tender versus non-tender dichotomy, and the number of joints that were classified as tender was recorded. The swollen joint count was calculated in the same manner. For CRP concentrations, blood samples were collected and sent to a central laboratory for assessment. For the VAS assessment, the participant used a 100 mm horizontal VAS to assess the severity of his or her arthritis where 0 = none and 100 = most severe. DAS28 scores range from \<2.6 (disease remission) to \>5.1 (high disease activity). |
| Percentage of Parts 2 and 3 Participants Who Achieved ACR50 and ACR70 | Day 43 | Clinical response to treatment was assessed according to ACR50 and ACR70 criteria. A participant was defined as an ACR50 or ACR70 responder if the following 3 conditions were met: 1) improvement of ≥50% or ≥ 70%, respectively, in the number of tender joints, 2) improvement of ≥50% or ≥ 70%, respectively, in the number of swollen joints and 3) improvement of ≥50% or ≥ 70%, respectively, in three of the following five domains: patient global assessment, physician global assessment, patient pain assessment, health assessment questionnaire (HAQ) and acute phase reactant |

Disease Activity Score (DAS28) of Parts 2 and 3 Participants
The DAS28 is a composite score based on tender and swollen joint counts, C reactive protein (CRP) concentrations, and the participant's global disease activity based on a visual analogue scale (VAS). The tender joint count (based on 28 joints) was calculated by scoring several different aspects of tenderness as assessed by pressure and joint manipulation on physical examination. The information on various types of tenderness was then collapsed into a single tender versus non-tender dichotomy, and the number of joints that were classified as tender was recorded. The swollen joint count was calculated in the same manner. For CRP concentrations, blood samples were collected and sent to a central laboratory for assessment. For the VAS assessment, the participant used a 100 mm horizontal VAS to assess the severity of his or her arthritis where 0 = none and 100 = most severe. DAS28 scores range from \<2.6 (disease remission) to \>5.1 (high disease activity).
Time frame: Day 43

Percentage of Parts 2 and 3 Participants Who Achieved ACR50 and ACR70
Clinical response to treatment was assessed according to ACR50 and ACR70 criteria. A participant was defined as an ACR50 or ACR70 responder if the following 3 conditions were met: 1) improvement of ≥50% or ≥ 70%, respectively, in the number of tender joints, 2) improvement of ≥50% or ≥ 70%, respectively, in the number of swollen joints and 3) improvement of ≥50% or ≥ 70%, respectively, in three of the following five domains: patient global assessment, physician global assessment, patient pain assessment, health assessment questionnaire (HAQ) and acute phase reactant
