To Evaluate The Effect Of SAR153191 (REGN88) Added To Other RA Drugs In Patients With RA Who Are Not Responding To Or Intolerant Of Anti-TNF Therapy (SARIL-RA-TARGET)

Study Summary

Primary Objective: To demonstrate that sarilumab added to disease modifying anti-rheumatic drugs (DMARDs) were effective for: * reduction of signs and symptoms at Week 24 and * improvement of physical function at Week 12 in participants with active rheumatoid arthritis (RA) who were inadequate responders or intolerant to tumor necrosis factor alpha (TNF-α) antagonists. Secondary Objectives: The secondary objectives were to investigate the effects of SAR153191 (REGN88) when added to DMARD therapy, in participants with active RA who were inadequate responders or intolerant to TNF-α antagonists, for: * Reduction of signs and symptoms at Week 12; * Improvement in physical function at Week 24; * Improvement in disease activity score as measured by other American College of Rheumatology (ACR) derived components at Weeks 12 and 24; * Improvement in quality of life as measured by participant reported outcomes (PROs) at intermediate visits and Week 24. To assess the exposure of sarilumab added to DMARD therapy in this population. To assess the safety of sarilumab in this population.

Primary Outcome

ACR responses are assessed with a composite rating scale of the American College of Rheumatology that includes 7 variables: tender joint count (TJC); swollen joint count (SJC); levels of an acute phase reactant (C-reactive Protein levels \[CRP\]); participant's assessment of pain; participant's global assessment of disease activity; physician's global assessment of disease activity; participant's assessment of physical function by (health assessment questionnaire disability index \[HAQ-DI\]).
