Secondary | Change From Baseline in Disease Activity Score (DAS28-ESR) at Week 24 | The DAS28 is a composite score to measure disease activity in patients with rheumatoid arthritis, derived from the following variables: The number of swollen and tender joints assessed using the 28-joint count; Erythrocyte sedimentation rate (ESR); Patient's global assessment of disease activity measured on a 100 mm visual analog scale. The DAS28 score ranges from zero to ten. A DAS28 score above 5.1 means high disease activity whereas a DAS28 less than or equal to 3.2 indicates low disease activity. Remission is achieved by a DAS28 lower than 2.6. |

A Good Response is defined as an improvement (decrease) in the DAS28 of more than 1.2 compared with Baseline and attainment of a DAS28 score of less than or equal to 3.2. A Moderate Response is defined as either: an improvement (decrease) in the DAS28 of greater than 0.6 and less than or equal to 1.2 from Baseline and attainment of a DAS28 score of less than or equal to 5.1 or, an improvement (decrease) in the DAS28 of more than 1.2 from Baseline and attainment of a DAS28 score of greater than 3.2. No Response is defined as either an improvement (decrease) in the DAS28 of less than or equal to 0.6, or an improvement (decrease) in the DAS28 of greater than 0.6 and less than or equal to 1.2 and attainment of a DAS28 of more than 5.1. |

A negative percentage change from baseline score indicates an improvement. |
Baseline, Week 24 and Week 48 | No |
Secondary | Percent Change From Baseline in Erythrocyte Sedimentation Rate | Erythrocyte sedimentation rate (ESR) indirectly measures how much inflammation is in the body.
