Participation in any interventional clinical trial with an unapproved investigational therapy within the 3 months before the start of this study (or within 5 half-lives of the investigated compound before study Day 1, whichever is longer) 6. Other protocol defined exclusion criteria could apply |

Primary | Percentage of Participants Achieving American College of Rheumatology 20 Response Based on C-reactive Protein (ACR20-CRP) at Week 26 | ACR20-CRP response is defined as greater than or equal to (>=) 20 percent (%) improvement in both tender joint counts (based on a total of 68 joints) and swollen joint counts (based on a total of 66 joints) together with >=20% improvement in at least 3 of the following 5 measures: 1) participant's assessment of pain; 2) participant's global assessment of disease activity; 3) physician's global assessment of disease activity; 4) participant's assessment of physical function; and 5) acute-phase marker (CRP). | Week 26 | No |
Secondary | Percentage of Participants Achieving American College of Rheumatology 50 Response Based on CRP (ACR50-CRP) at Week 26 | ACR50-CRP response is defined as >=50% improvement in both tender joint counts (based on a total of 68 joints) and swollen joint counts (based on a total of 66 joints) together with >=50% improvement in at least 3 of the following 5 measures: 1) participant's assessment of pain; 2) participant's global assessment of disease activity; 3) physician's global assessment of disease activity; 4) participant's assessment of physical function; and 5) acute-phase marker (CRP). | Week 26 | No |
Secondary | Percentage of Participants Achieving American College of Rheumatology 70 Response Based on CRP (ACR70-CRP) at Week 26 | ACR70-CRP response is defined as >=70% improvement in both tender joint counts (based on a total of 68 joints) and swollen joint counts (based on a total of 66 joints) together with >=70% improvement in at least 3 of the following 5 measures: 1) participant's assessment of pain; 2) participant's global assessment of disease activity; 3) physician's global assessment of disease activity; 4) participant's assessment of physical function; and 5) acute-phase marker (CRP). | Week 26 | No |
Secondary | Percentage of Participants Achieving Disease Activity Score in 28 Joints (DAS28) Based on CRP (DAS28-CRP) of Less Than or Equal to (<=) 3.2 at Week 26 | DAS28-CRP incorporates non-graded joint counts for tenderness and swelling based on a total of 28 joints, CRP as a marker of inflammation, and a general health assessment using a 100-millimeter (mm) visual analog scale (the participant's global assessment of disease activity). DAS28 ranges between 0 and 10 representing current disease activity. A value above 5.1 represents high disease activity, a value below 3.2 represents low disease activity, and a value below 2.6 represents remission. | Week 26 | No |
Secondary | Percentage of Participants Achieving Disease Activity Score in 28 Joints (DAS28) Based on CRP (DAS28-CRP) of <=2.6 at Week 26 | DAS28-CRP incorporates non-graded joint counts for tenderness and swelling based on a total of 28 joints, CRP as a marker of inflammation, and a general health assessment using a 100 mm visual analog scale (the participant's global assessment of disease activity). DAS28 ranges between 0 and 10 representing current disease activity. A value above 5.1 represents high disease activity, a value below 3.2 represents low disease activity, and a value below 2.6 represents remission. | Week 26 | No |
Secondary | Percentage of Participants Achieving Improvement in Health Assessment Questionnaire Disability Index (HAQ-DI) of at Least 0.3 From Baseline at Week 26 | The HAQ-DI is a 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 was scored on 4-point scale from 0 to 3: 0 = no difficulty; 1 = some difficulty; 2 = much difficulty; 3 = unable to do. Overall score was computed as the sum of domain scores and divided by the number of domains answered. Total possible score range is 0 to 3 where 0 = least difficulty and 3 = extreme difficulty. Percentage of participants achieving improvement in HAQ-DI of at least 0.3 from baseline at Week 26 was reported. | Week 26 | No |
Secondary | Percentage of Participants With Good or Moderate European League Against Rheumatism (EULAR) Response at Week 26 | The EULAR response criteria evaluate change in DAS28 scores represented as "good response", "moderate response", or "no response" considering both the current DAS28 score and the observed improvement from baseline. Participants were considered to have "good" or "moderate" EULAR response if at the time of assessment, their DAS28 score was <=5.1 and the improvement from baseline in their DAS28 score was greater than (>) 0.6; or if at the time of assessment, their DAS28 score was >5.1 and improvement from baseline in their DAS28 score was >1.2. | Week 26 | No |
Secondary | Number of Participants With Adverse Events (AEs) and Serious Adverse Events (SAEs) | An AE was defined as any new untoward medical occurrences/worsening of pre-existing medical condition without regard to possibility of causal relationship. An SAE was an AE that resulted in any of the following outcomes: death; life threatening; persistent/significant disability/incapacity; initial or prolonged inpatient hospitalization; congenital anomaly/birth defect. | Baseline up to Week 38 | Yes |
