The DAS28-3 (ESR) is a measure of disease activity in rheumatoid arthritis. It is calculated from the number of swollen joint count (SJC) and tender joint count (TJC) using the 28 joints count, and ESR (millimeters per hour [mm/hr]). Total score ranges from 0 to 9.4, where higher score indicated more disease activity. Decrease in score indicated improvement in disease activity.

The primary effectiveness population included all participants who received at least one dose of a second biologic therapy at Baseline, had only one previous biologic therapy, and contributed to 24-week DAS28-ESR primary endpoint analysis.

The TJC is the most specific clinical method to quantify abnormalities in participants with rheumatoid arthritis (RA). A total of 28 joints were assessed for tenderness. Decrease in score indicated an improvement in disease activity.

The primary effectiveness population included all participants who received at least one dose of a second biologic therapy at Baseline, had only one previous biologic therapy, and contributed to 24-week DAS28-ESR primary endpoint analysis.

C-reactive protein (CRP) is an inflammation marker. Normal range is from 0-10 milligram/Liter. A decrease in the level of CRP indicates reduction in inflammation and therefore improvement in disease activity.

The primary effectiveness population included all participants who received at least one dose of a second biologic therapy at Baseline, had only one previous biologic therapy, and contributed to 24-week DAS28-ESR primary endpoint analysis. Participants with available data at specified time points were analyzed and are denoted as 'n'.

The ESR is a laboratory test that provides a non-specific measure of inflammation. The test assesses the rate at which red blood cells sediment in a period of one hour. Normal range is 0-30 mm/hr. A reduction in the level of ESR is considered as an improvement in disease activity.

The primary effectiveness population included all participants who received at least one dose of a second biologic therapy at Baseline, had only one previous biologic therapy, and contributed to 24-week DAS28-ESR primary endpoint analysis. Participants with available data at specified time points were analyzed and are denoted as 'n'.

Physician global assessment of disease was measured on a 0 to 100 millimeter (mm) visual analog scale (VAS), with 0 mm = no disease activity and 100 mm = highest possible disease activity. Higher scores indicate worsening of disease.

Participants with available data at specified time points were analyzed and are denoted as 'n'.

Participants were asked to assess their pain intensity (severity of pain) on a 100-millimeter (mm) VAS with the left edge (0 mm) defined as "no pain" and the right edge (100 mm) defined as "severest pain". Higher scores indicate worsening of disease.

The primary effectiveness population included all participants who received at least one dose of a second biologic therapy at Baseline, had only one previous biologic therapy, and contributed to 24-week DAS28-ESR primary endpoint analysis. Participants with available data at specified time points were analyzed and are denoted as 'n'.

Health Assessment Questionnaire-Disability Index (HAQ-DI) is participant reported assessment of ability to perform tasks in 8 categories of daily living activities as dress/groom, arise, eat, walk, reach, grip, hygiene, and common activities over past week. Each item was scored on a 4-point scale from 0 to 3, where 0=no difficulty, 1=some difficulty, 2=much difficulty, and 3=unable to do. Overall score was computed as the sum of domain scores divided by the number of domains answered. Total possible score range was 0-3, where 0 = least difficulty and 3 = extreme difficulty.

The primary effectiveness population included all participants who received at least one dose of a second biologic therapy at Baseline, had only one previous biologic therapy, and contributed to 24-week DAS28-ESR primary endpoint analysis. Participants with available data at specified time points were analyzed and are denoted as 'n'.

Duration of morning stiffness is defined as the time elapsed when participant woke up in the morning and was able to resume normal activities without stiffness in minutes. Participants with available data at the time of assessment were included in the analysis.

The primary effectiveness population included all participants who received at least one dose of a second biologic therapy at Baseline, had only one previous biologic therapy, and contributed to 24-week DAS28-ESR primary endpoint analysis.

An Adverse event is defined as any unfavorable and unintended medical occurrence/sign (including an abnormal laboratory finding), symptom or disease in a participant administered a pharmaceutical product and which does not necessarily have a causal relationship with this treatment. A serious adverse event is defined as any untoward medical occurrence that, at any dose, results in death, is life threatening, requires hospitalization or prolongation of existing hospitalization, results in disability/incapacity, is a congenital anomaly/birth defect, or is medically significant or requires intervention to prevent one or other of the outcomes listed above.

The participant characteristics included participant's option for treatment and option for follow-up.
