Rheumatoid Arthritis
Conditions
Brief summary
Primary Objective: To assess the effect of sarilumab in combination with conventional synthetic Disease-Modifying Anti-Rheumatic Drug (csDMARD) and/or monotherapy on participant-reported impact of disease, using the rheumatoid arthritis impact of disease (RAID) questionnaire, in participants with moderately to severely active rheumatoid arthritis (RA) and inadequate response or intolerance to current csDMARD or tumor necrosis factor (TNF) inhibitors. Secondary Objectives: * To assess the change of the RAID score from baseline (to Week 4, Week 12, and Week 24) in participants with moderately to severely active RA and inadequate response or intolerance to current csDMARD or TNF inhibitors, treated with sarilumab in combination with csDMARD and/or monotherapy. * To assess the effect of sarilumab in combination with csDMARD and/or monotherapy on other participant-reported outcomes (global assessment of disease activity, disability, morning stiffness, fatigue, anxiety/depression, mood disorders, and physical activities) in participants with moderately to severely active RA and inadequate response or intolerance to current csDMARD or TNF inhibitors. * To assess the efficacy of sarilumab in combination with csDMARD and/or monotherapy using disease activity score-28 for RA with erythrocyte sedimentation rate (DAS28-ESR) and clinical disease activity index in participants with moderately to severely active RA and inadequate response or intolerance to current csDMARD or TNF inhibitors. * To assess the safety of sarilumab in combination with csDMARD and/or monotherapy in participants with moderately to severely active RA and inadequate response or intolerance to current csDMARD or TNF inhibitors.

| Measure | Time frame | Description |
|---|---|---|
| Change From Baseline in Rheumatoid Arthritis Impact of Disease Total Score at Week 24 | Baseline, Week 24 | RAID was a participant reported outcome measure used to evaluate the impact of RA on participant's quality of life which comprised 7 domains: • pain, • function, • fatigue, • physical and psychological well-being, • sleep disturbance, and • coping. Each domain was a single question scored on a 0 to 10 continuous NRS. The values for each of these domains were weighed by participant assessment of relative importance and combined in a single value. Total RAID score range was 0 (not affected, very good) to 10 (most affected), where higher value indicated worse status. |

Number of Participants Achieving Low Disease Activity (DAS28 ESR Score <=3.2) and Remission (DAS28 ESR Score <2.6) at Weeks 12, and 24
DAS28-ESR was a composite score that included 4 variables: TJC (based on 28 joints); SJC (based on 28 joints); participant's global assessment of health activity using 100 mm VAS: range 0 (no pain) to 100 (maximum pain imaginable) marker of inflammation assessed by ESR in mm/h. DAS28-ESR total score ranged from 0-10, higher score indicated more disease activity. The DAS28-ESR score provided a number indicating the current disease activity of the RA. A DAS28-ESR score above 5.1 indicated high disease activity, DAS28-ESR score \<= 3.2 indicated LDA, \> 3.2 to \<=5.1 implied moderate disease activity and DAS28-ESR score below 2.6 indicated disease remission.
Time frame: Weeks 12 and 24

Number of Participants With Treatment-emergent Adverse Events (TEAEs) and Serious Adverse Events (SAEs)
An adverse event (AE) was defined as any untoward medical occurrence in a participant who received study drug and did not necessarily had a causal relationship with the study treatment. SAE: Any untoward medical occurrence that resulted in any of the following outcomes: death, life-threatening, required initial or prolonged in-patient hospitalization, persistent or significant disability/incapacity, congenital anomaly/birth defect, or considered as medically important event. TEAEs were defined as AEs that occurred in the time from the first injection of study drug up to 39.7 weeks.
Time frame: Baseline up to end of study (up to 39.7 weeks)
Population: Analysis was performed on safety population which included participants who signed the informed consent form and had exposed to at least one dose or part of a dose of study drug.

Rheumatoid Arthritis Impact of Disease Total Score at Baseline, Weeks 4, 12 and 24
RAID was a participant reported outcome measure used to evaluate the impact of RA on participant's quality of life which comprised 7 domains: • pain, • function, • fatigue, • physical and psychological well-being, • sleep disturbances, and • coping. Each domain was a single question scored on a 0 to 10 continuous NRS. The values for each of these domains were weighed by participant assessment of relative importance and combined in a single value. Total RAID score range was 0 (not affected, very good) to 10 (most affected), where higher value indicated worse status.

Stanford Health Assessment Questionnaire Disability Index (HAQ-DI) Total Score at Baseline, Weeks 4, 12 and 24
HAQ-DI was a participant-oriented questionnaire developed specifically to assess the extent of a RA participant's functional ability. It consisted of at least 2 or 3 questions per category, 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 (at each specified visit) rated on a 4-point scale where 0 = no difficulty; 1 = some difficulty; 2 = much difficulty; 3 = unable to do. Overall score was computed as the sum of category scores and divided by the number of categories answered, and ranged from 0 to 3, where 0 = no disability and 3 = completely disabled, higher score indicated more disability.
