Measure Description |
Time Frame |
|---|---|---|
|
Percentage of Participants Reporting Any Adverse Event - Overall Summary of Events
Time Frame: Baseline and Weeks 2, 4, 8, 12, 16, 20, and 24
|
Percentage of participants with a serious adverse event (SAE), who died, with an adverse event (AE), or study drug related AE during the study.
|

Measure Description |
Time Frame |
|---|---|---|
|
Percentage of Participants by Disease Activity Score Based on 28-Joint Count (DAS28) Category
Time Frame: Baseline and Weeks 4, 8, 12, 16, 20, and 24
|
DAS28 was calculated from the number of swollen joints and tender joints using the 28-joint count, the erythrocyte sedimentation rate (ESR) (millimeters per hour [mm/hr]) and global health assessment (participant rated global assessment of disease activity using 10-mm Visual analog scale - VAS); DAS28 score ranged from 0 to 10, where higher scores correspond to greater disease activity.
A DAS28 score of greater than (>)5.1 indicated high disease activity, a score of >3.2 but less than or equal to (≤)5.1 indicated moderate disease activity, a score of greater than or equal to (≥)2.6 but ≤3.2 indicated low disease activity, and a score of less than <2.6 indicated disease remission.
Week 24 is the Follow-Up visit.

Percentage of Participants Achieving a Clinically Meaningful Improvement as Measured by DAS28
Time Frame: Weeks 4, 8, 12, 16, 20, and 24
|
DAS28 was calculated from the number of swollen joints and tender joints using the 28-joint count, the ESR (mm/hr) and global health assessment (participant rated global assessment of disease activity using 10-mm VAS); DAS28 score ranged from 0 to 10, where higher scores correspond to greater disease activity.
Participants achieved a clinically meaningful improvement in DAS28 if there was a reduction of at least 1.2 units from baseline.
|
Weeks 4, 8, 12, 16, 20, and 24
|
|
Time to DAS28 Response by DAS28 Category
Time Frame: Weeks 4, 8, 12, 16, 20, and 24
|
Time to response is the number of days from date of first infusion to date of event.
DAS28 response was defined as achievement of Low Disease Activity (DAS28 ≥2.6 to ≤3.2), Remission (DAS28 <2.6), or Clinically Meaningful Improvement (change of >1.2 from baseline).
|
Weeks 4, 8, 12, 16, 20, and 24
|
|
Percentage of Participants With a Change From Baseline in Health Assessment Questionnaire - Disability Index (HAQ-DI) of at Least 0.22 Units
Time Frame: Weeks 4, 8, 12, 16, 20, and 24
|
HAQ includes 20 questions concerning participant's activities of daily life, grouped in 8 scales of 2 to 3 questions for each activity.
To respond to each question, a four-level response (score of 0 to 3 points), with higher scores showing larger functional limitations, was chosen.
Scoring was as follows with respect to performance of participant's everyday activities: 0=without difficulties; 1= with some difficulties; 2=with great difficulties; and 3=unable to perform these actions at all.
Minimum score was 0, maximum score was 3.

Percentage of Participants With Improvement in Physical Function by HAQ-DI Category
Time Frame: Baseline, Weeks 4, 8, 12, 16, 20, and 24
|
Physical function scoring was as follows with respect to performance of participant's everyday activities: 0=without difficulties; 1= with some difficulties; 2=with great difficulties; and 3=unable to perform these actions at all.
Minimum score was 0, maximum score was 3. The HAQ-DI score at every visit was categorized into none to mild disability (HAQ-DI <1), moderate disability (1≤ HAQ-DI <2) and severe disability (HAQ-DI ≥2).
The percentages of the participants falling in each of these categories with respect to the visits were determined.

C-Reactive Protein (CRP) Values by Study Visit
Time Frame: Baseline and Weeks 4, 8, 12, 16, 20, and 24
|
CRP is an acute phase inflammatory marker.
The serum concentration of CRP is measured in milligrams per liter (mg/L).
A reduction in the level is considered an improvement.

Erythrocyte Sedimentation Rate
Time Frame: Baseline and Weeks 4, 8, 12, 16, 20, and 24
|
ESR (measured in mm/hr) is an inflammation marker used to determine acute phase response.
