- Change From Baseline in Disease Activity Score 28 C-reactive Protein [DAS28-CRP]) at Week 12 [ Time Frame: Baseline, Week 12 ]The DAS28-CRP is a composite index used to assess rheumatoid arthritis disease activity, calculated based on the tender joint count (out of 28 evaluated joints), swollen joint count (out of 28 evaluated joints), Patient's Global Assessment of Disease Activity (0-100 mm), and high-sensitivity C-reactive protein (hsCRP; in mg/L). Scores on the DAS28-CRP range from 0 to approximately 10, where higher scores indicate more disease activity. A negative change from baseline indicates improvement in disease activity.
- Change From Baseline in Clinical Disease Activity Index (CDAI) [ Time Frame: Baseline, Week 2, Week 4, Week 8, and Week 12 ]The CDAI is a composite index for assessing disease activity based on the summation of the total tender joint count (out of 28 evaluated joints), swollen joint count (out of 28 evaluated joints), patient global assessment of disease activity measured on a VAS from 0 to 10 cm, and physician global assessment of disease activity measured on a VAS from 0 to 10 cm. The total CDAI score ranges from 0 to 78 with higher scores indicating higher disease activity. A negative change from baseline indicates improvement in disease activity.
- Change From Baseline in Simplified Disease Activity Index (SDAI) [ Time Frame: Baseline, Week 2, Week 4, Week 8, and Week 12 ]The SDAI is a validated measure of rheumatoid arthritis disease activity. Twenty-eight tender joint counts, 28 swollen joint counts, global disease activity assessed by the participant on a visual analogue scale from 0 to 10 (cm), global disease activity assessed by an investigator on a visual analogue scale from 0 to 10 (cm), and serum levels of C-reactive protein (CRP; mg/dL) were included in the SDAI score. Scores on the SDAI range from 0 to 86.with higher scores indicating higher disease activity. A negative change from baseline indicates improvement in disease activity.
- Percentage of Participants Achieving Clinical Remission (CR) Based on Disease Activity Score 28 C-reactive Protein [DAS28-CRP]) at Week 12 [ Time Frame: At Week 12 ]The DAS28-CRP is a composite index used to assess rheumatoid arthritis disease activity, calculated based on the tender joint count (out of 28 evaluated joints), swollen joint count (out of 28 evaluated joints), Patient's Global Assessment of Disease Activity (0-100 mm), and high-sensitivity C-reactive protein (hsCRP; in mg/L). Scores on the DAS28-CRP range from 0 to approximately 10, where higher scores indicate more disease activity. Clinical remission (CR) based on DAS28 (CRP) is defined as achieving a DAS28 (CRP) of less than 2.6.

Scores on the DAS28-CRP range from 0 to approximately 10, where higher scores indicate more disease activity.

- Percentage of Participants Achieving Low Disease Activity (LDA) Based on Clinical Disease Activity Index (CDAI) Criteria [ Time Frame: Week 2, Week 4, Week 8, and Week 12 ]The CDAI is a composite index for assessing disease activity based on the summation of the total tender joint count (out of 28 evaluated joints), swollen joint count (out of 28 evaluated joints), patient global assessment of disease activity measured on a VAS from 0 to 10 cm, and physician global assessment of disease activity measured on a VAS from 0 to 10 cm. The total CDAI score ranges from 0 to 78 with higher scores indicating higher disease activity. Low Disease Activity (LDA) based on CDAI is defined as achieving a CDAI of less than or equal to 10.
- Percentage of Participants Achieving Complete Remission (CR) Based on Clinical Disease Activity Index (CDAI) Criteria [ Time Frame: Week 2, Week 4, Week 8, and Week 12 ]The CDAI is a composite index for assessing disease activity based on the summation of the total tender joint count (out of 28 evaluated joints), swollen joint count (out of 28 evaluated joints), patient global assessment of disease activity measured on a VAS from 0 to 10 cm, and physician global assessment of disease activity measured on a VAS from 0 to 10 cm.

Participants assessed their ability to do each task on a scale from 0 (without any difficulty) to 3 (unable to do). Scores were averaged to provide an overall score ranging from 0 to 3, where 0 represents no disability and 3 represents very severe, high-dependency disability. A negative change from baseline in the overall score indicates improvement.
- Change From Baseline in High-Sensitivity C-reactive Protein (hsCRP) [ Time Frame: Baseline, Week 2, Week 4, Week 8, and Week 12 ]C-reactive protein is a blood test marker for inflammation in the body, and levels rise in response to inflammation. A negative change from baseline in indicates improvement.

Twenty-eight tender joint counts, 28 swollen joint counts, the erythrocyte sedimentation rate (ESR; mm/hour), and the participant's assessment of global disease activity (on a visual analog scale [VAS] from 0 to 100 mm) are included in the DAS28 -ESR score. Scores on the DAS28-ESR range from 0 to 10; higher scores indicate more disease activity.
- Change From Baseline in Morning Stiffness Severity [ Time Frame: Baseline, Week 2, Week 4, Week 8, and Week 12 ]Morning stiffness severity was assessed by a numeric rating-scale (NRS). Participants rated the severity of morning stiffness during the past week from 0 to 10 with 0 representing "not severe" and 10 "very severe". Negative values indicate improvement from baseline.
- Percentage of Participants Achieving Minimal Clinically Important Difference (MCID) in Change From Baseline in Health Assessment Questionnaire Disability Index (HAQ-DI) [ Time Frame: Baseline, Week 2, Week 4, Week 8, and Week 12 ]The Health Assessment Questionnaire - Disability Index is a patient-reported questionnaire that measures the degree of difficulty a person has in accomplishing tasks in 8 functional areas (dressing, arising, eating, walking, hygiene, reaching, gripping, and errands and chores) over the past week. Participants assessed their ability to do each task on a scale from 0 (without any difficulty) to 3 (unable to do).
