Percentage of Participants Achieving American College of Rheumatology (ACR) 20 Percent (%) Improvement (ACR20 Response) at Week 24
Time Frame: Week 24
|
ACR20 response: greater than or equal to (≥) 20% improvement in tender or swollen joint counts and 20% improvement in 3 of the following 5 criteria: 1) Physician's global assessment of disease activity, 2) participant assessment of disease activity, 3) Patient Assessment of Pain (visual analog scale [VAS]), 4) participant assessment of functional disability via a Health Assessment Questionnaire (HAQ), and 5) erythrocyte sedimentation rate (ESR) at each visit.

HAQ Disability Index (HAQ-DI) Score at Baseline and Week 24
Time Frame: Baseline and Week 24
|
HAQ-DI is a participant-reported questionnaire specific for rheumatoid arthritis.
It consists of 20 questions referring to 8 component sets: dressing/grooming, arising, eating, walking, hygiene, reach, grip, and activities.
Each domain has at least 2 component questions.
There are 4 possible responses for each component 0=without any difficulty 1=with some difficulty 2=with much difficulty 3=unable to do.
To calculate HAQ-DI the participant must have a domain score for at least 6 of 8 domains.
The HAQ-DI is the sum of the scores, divided by the number of domains that have a score (in range 6-8) for a total possible score minimum/maximum 0 (best) to 3 (worst).

Baseline and Week 24
|
|
Functional Assessment of Chronic Illness Therapy - Fatigue (FACIT-F) Score at Baseline and Week 24
Time Frame: Baseline and Week 24
|
FACIT-F is a 13-item questionnaire.
Participants scored each item on a 5-point scale: 0 (Not at all) to 4 (Very much).
The larger the response to the questions (with the exception of 2 negatively stated), the greater the fatigue.
For all questions, except for the 2 negatively stated ones, the code was reversed and a new score was calculated as (4 minus the participants response).
The sum of all responses resulted in the FACIT-Fatigue score for a total possible score of 0 (worse score) to 52 (better score).
A higher score reflects an improvement in the health status.

Baseline and Week 24
|
|
Disease Activity Score Based on 28 Joint Count - Erythrocyte Sedimentation Rate (DAS28-ESR) at Baseline and Week 24
Time Frame: Baseline and Week 24
|
DAS28-ESR calculated from the number of swollen joints and tender joints using the 28 joints count, the ESR (millimeters per hour [mm/hour]) and Patient's Global Assessment of disease activity (participant rated arthritis activity assessment) with transformed scores ranging 0 to 10; higher scores indicated greater affectation due to disease activity.
DAS28 less than or equal to (≤)3.2 equals (=) low disease activity, DAS28 greater than (>)3.2 to 5.1 = moderate to high disease activity.
|
Baseline and Week 24
|
|
Percentage of Participants With Disease Remission at Week 24 Assessed Using DAS28-ESR
Time Frame: Week 24
|
DAS28-ESR calculated from the number of swollen joints and tender joints using the 28 joints count, the ESR (mm/hour) and Patient's Global Assessment of disease activity (participant rated arthritis activity assessment) with transformed scores ranging 0 to 10; higher scores indicated greater affectation due to disease activity.
DAS28 <2.6=remission.
|
Week 24
|
|
Percentage of Participants With Low Disease Activity at Week 24 Assessed Using DAS28-ESR
Time Frame: Week 24
|
DAS28-ESR calculated from the number of swollen joints and tender joints using the 28 joints count, the ESR (mm/hour) and Patient's Global Assessment of disease activity (participant rated arthritis activity assessment) with transformed scores ranging 0 to 10; higher scores indicated greater affectation due to disease activity.
DAS28 >2.6 and <3.2=low disease activity.
|
Week 24
|
|
Time to Onset of ACR20/50/70 Response
Time Frame: Weeks 4, 8, 12, 16, 20, and 24
|
Time to onset of ACR 20/50/70 response was calculated as the number of weeks from the administration of the first dose of study drug until the date of first achievement of ACR 20/50/70 per criteria.
|
Weeks 4, 8, 12, 16, 20, and 24
