safety of tofacitinib in routine care patients with rheumatoid arthritis (star-ra)- cardiovascular endpoints

Conditions: Rheumatoid Arthritis

Summary: there are two main aims of this study. first aim is to compare the risk of cardiovascular events (including myocardial infarction or stroke), between patients treated with tofacitinib and patients treated with tnf inhibitors (tnfi) for rheumatoid arthritis (ra) among, 1) "real world evidence (rwe)" cohorts including routine care patient population from the us and, 2) "randomized controlled trial (rct) duplicate" cohorts including routine care patient population who meet inclusion and exclusion criteria of the safety study of tofacitinib versus tumor necrosis factor (tnf) inhibitor in subjects with rheumatoid arthritis ("oral surveillance", nct02092467) clinical trial. second aim is to examine the risk of myocardial infarction, stroke, heart failure hospitalization, coronary revascularization, and all-cause mortality as separate endpoints when comparing tofacitinib with tnfi in patients with ra among, 1) "real world evidence (rwe)" cohort including routine care patient population from the us and, 2) "randomized controlled trial (rct) duplicate" cohort including routine care patient population who meet inclusion and exclusion criteria of the safety study of tofacitinib versus tumor necrosis factor (tnf) inhibitor in subjects with rheumatoid arthritis ("oral surveillance", nct02092467) clinical trial.
