Primary Objectives:
Part A (dose ranging study):
To demonstrate that sarilumab (SAR153191/REGN88) on top of MTX was effective on reduction of signs and symptoms of rheumatoid arthritis at 12 weeks.
Part B (pivotal study):
To demonstrate that sarilumab added to MTX was effective in:
- reduction of signs and symptoms of rheumatoid arthritis at 24 weeks
- inhibition of progression of structural damage at 52 weeks
- improvement in physical function at 16 weeks
Secondary Objectives:
Part B:
To demonstrate that sarilumab added to MTX was effective in induction of a major clinical response at 52 weeks
To assess the safety of sarilumab added to MTX
To document the pharmacokinetic profile of sarilumab added to MTX in participants with active rheumatoid arthritis who were inadequate responders to MTX therapy.

- Part A: Percentage of Participants Achieving American College of Rheumatology 20% (ACR20) Response at Week 12 [ Time Frame: Baseline to Week 12 ]ACR20 response was defined, based on guidelines set forth by the American College of Rheumatology (ACR), as ≥20 % improvement in tender joint count and swollen joint count as well as ≥20% improvement in at least 3 of 5 following measures: C-Reactive Protein (CRP), Participant assessment of pain; Participant's global assessment of disease activity; Physician global assessment of disease activity; and Health Assessment Question-Disability Index (HAQ-DI). Missing data imputed by Last Observation Carried Forward (LOCF).
- Part B: Percentage of Participants Achieving ACR20 Response at Week 24 [ Time Frame: Baseline to Week 24 ]ACR20 improvement responses were determined without imputation of missing post-baseline values. In addition data collected after treatment discontinuation or rescue was set to missing. Responder status was determined if possible. With these rules, participants automatically became non-responders for all time points beyond the time point they started rescue treatment or discontinued study treatment.
- Part B: Change From Baseline in Health Assessment Question Disability Index (HAQ-DI) at Week 16 [ Time Frame: Baseline, Week 16 ]HAQ-DI was a participant-reported questionnaire that assesses the difficulty of performing daily activities: dress/groom, arise, eat, walk, reach, grip, hygiene and common activities. Overall score range from 0=least difficulty to 3=extreme difficulty. An increase in the score indicates a worsening of physical function while a decrease in the score represents improvement. Data collected after treatment discontinuation was set to missing.
- Part B: Change From Baseline in Van Der Heijde Modified Total Sharp Score (mTSS) at Week 52 [ Time Frame: Baseline, Week 52 ]The Sharp method modified by D. van der Heijde involves separate scores for erosions and joint space narrowing based on radiographs to assess the degree of structural damage. Total score range from 0 (normal) to 448 (worst possible total score). An increase in total score represents progression of structural damage. Missing data were imputed by the linear extrapolation method.
- Part B: Percentage of Participants Achieving a Major Clinical Response at Week 52 [ Time Frame: Baseline up to Week 52 ]Major clinical response was defined as an ACR70 response maintained for at least 24 consecutive weeks. ACR70 response uses the same criteria as for ACR20 but requires 70% improvement. In the primary approach, data collected after treatment discontinuation or rescue was set to missing. No imputation of missing post-baseline values was performed. Responder status was determined if possible. With these rules, participants automatically became non-responders for all time points beyond the time point they started rescue treatment or discontinued study treatment.
