Rheumatoid Arthritis
Conditions
Brief summary
This retrospective cohort study will analyze data from multiple large U.S. health insurance claims databases to compare use of tocilizumab to other biologic disease-modifying anti-rheumatic drugs (DMARDs) in real world patients with RA. Using the date of dispensing as the index date, the analysis will compute the time to first event for several cardiovascular outcomes.
Interventions
Exposure data will be gathered from claims databases, and no medicine will be administered in this non-interventional study. There are no protocol-specified biologic agents, although the analyses will be stratified by TNFi and non-TNFi targeted therapies. The drug selection and regimen are at the discretion of the prescribing physician.
