Outcomes

Primary Outcomes

Percentage of Participants Achieving American College of Rheumatology 20% Improvement (ACR20)

ACR20 Responder Index is a composite of clinical, laboratory, and functional measures in rheumatoid arthritis (RA). "ACR20 Responder" is a participant who has at least 20% improvement in both tender and swollen joint counts and in at least 3 of the following 5 criteria: Physician's Global Assessment of Disease Activity, Patient's Global Assessment of Disease Activity using visual analog scale (VAS), Health Assessment Questionnaire - Disability Index (HAQ-DI), pain due to arthritis, and high-sensitivity C-reactive protein (hsCRP). Participants with missing responses and participants who discontinue study or drug or are rescued before analysis timepoint are deemed non-responders.

Time frame: Week 12

Secondary Outcomes

Change From Baseline in the Health Assessment Questionnaire-Disability Index (HAQ-DI) Score

The HAQ-DI questionnaire assesses the participant's self-perception on the degree of difficulty (0 \[without any difficulty\], 1 \[with some difficulty\], 2 \[with much difficulty\], and 3 \[unable to do\])when dressing and grooming, arising, eating, walking, hygiene, reaching, gripping, and performing other daily activities. Scores for each functional area were averaged to calculate the HAQ-DI score, which ranged from 0 (no disability) to 3 (worst disability). A decrease in HAQ-DI score indicated an improvement in the participant's condition.

Time frame: Baseline, Week 12

Change From Baseline in the Disease Activity Score Based on a 28-Joint Count and High-sensitivity C-reactive Protein (DAS28-hsCRP)

Disease Activity Score (DAS) modified to include 28 joint count (DAS28) consisted of composite score of following variables: tender joint count (TJC28), swollen joint count (SJC28), C-reactive protein (CRP) (milligrams per liter), and Patient's Global Assessment of Disease Activity using visual analog scale (VAS) (participant global VAS). DAS28 was calculated using following formula: DAS28-CRP=0.56\*square root (sqrt)(TJC28)+0.28\*sqrt(SJC28)+0.36\*natural log(CRP+1)+0.014\*Patient's Global VAS+0.96. Scores ranged 1.0-9.4, where lower scores indicated less disease activity.

Percentage of Participants Achieving Simplified Disease Activity Index (SDAI) ≤3.3

SDAI is a tool for measurement of disease activity in RA that integrates TJC28, SJC28, acute phase response using C-reactive protein (milligrams per liter), Participant's Global Assessment of Disease Activity using VAS centimeters (cm), and Physician's Global Assessment of Disease Activity using VAS (cm). The SDAI is calculated by summing the values of the 5 components. Lower scores indicated less disease activity. An index-based definition of remission occurs with an SDAI score ≤3.3.

Time frame: Week 12

Mean Duration of Morning Joint Stiffness(MJS) in the Prior 7 Days as Collected in Electronic Daily Diaries

Participants reported the duration of their morning joint stiffness (MJS) in hours and minutes into daily electronic diaries. If MJS duration was longer than 12 hours (720 minutes), it was truncated to 720 minutes for statistical presentations and analyses. The average value across the 7 days preceding each visit is calculated. A decrease in duration of MJS indicated an improvement in the participant's condition.

Time frame: Week 12

Mean Severity of Morning Joint Stiffness Numeric Rating Scale (NRS) in the Prior 7 Days as Collected in Electronic Diaries

Participants rated the severity of their MJS by selecting a number from 0 to 10 that best described their overall level of MJS from the time they woke up, where 0 represents "no joint stiffness" and 10 represents "joint stiffness as bad as you can imagine". Participants reported their severity daily in electronic diaries. The average value across the 7 days preceding each visit is calculated. A decrease in severity rating indicated an improvement in the participant's condition.

Time frame: Week 12

Mean Worst Tiredness Numeric Rating Scale (NRS) in the Prior 7 Days as Collected in Electronic Diaries

Participants rated their tiredness by selecting a number from 0 to 10 that best described their level of worst tiredness during the past 24 hours, where 0 represents "no tiredness" and 10 represents "as bad as you can imagine". Participants reported their worst tiredness in daily electronic diaries. The average value across the 7 days preceding each visit is calculated. A decrease in tiredness severity rating indicated an improvement in the participant's condition.

Time frame: Week 12

Mean Worst Joint Pain Numeric Rating Scale (NRS) in the Prior 7 Days as Collected in Electronic Diaries

Participants rated their joint pain by selecting a number from 0 to 10 that best described their worst joint pain during the last 24 hours, where 0 represents "no pain" and 10 represents "pain as bad as you can imagine". Participants reported their worst joint pain in daily electronic diaries. The average value across the 7 days preceding each visit is calculated. A decrease in joint pain severity rating indicated an improvement in the participant's condition.

Change From Baseline in European Quality of Life-5 Dimensions-5 Level (EQ-5D-5L) Scores

European Quality of Life-5 Dimensions-5 Level (EQ-5D-5L) is a standardized measure of health status of the participant. One component consists of a descriptive system of the respondent's health comprised of the following 5 participant-reported dimensions: mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. Each dimension has 5 levels: no problems, slight problems, moderate problems, severe problems, and extreme problems. The responses are used to derive the health state index scores using the United Kingdom (UK) algorithm, with scores ranging from -0.594 to 1, and the United States (US) algorithm, with scores ranging from -0.109 to 1. A higher score indicates better health state.

Time frame: Baseline Week 12; Baseline Week 24

Change From Baseline in European Quality of Life-5 Dimensions-5 Level (EQ-5D-5L) Scores (Self-Perceived Health)

A second component of the EQ-5D-5L is a self-perceived health score which is assessed using a VAS that ranges from 0 to 100 millimeter (mm), where 0 indicates the worst health you can imagine and 100 indicates the best health you can imagine.

Time frame: Baseline Week 12; Baseline Week 24

Change From Baseline in Work Productivity and Activity Impairment-Rheumatoid Arthritis (WPAI-RA) Scores

The Work Productivity and Activity Impairment-Rheumatoid Arthritis (WPAI-RA) questionnaire was developed to measure the effect of general health and symptom severity on work productivity and regular activities in the 7 days prior to the visit. It contains 6 items covering overall work productivity (health), overall work productivity (symptom), impairment of regular activities (health), and impairment of regular activities (symptom). Scores are calculated as impairment percentages. The WPAI-RA yields four types of scores: Absenteeism (work time missed), Presenteeism (impairment at work), Work productivity loss (overall work impairment), and Activity impairment.
