A Study to Understand How Effective is Tofacitinib When Compared to Other Advanced Treatments in Patients With Rheumatoid Arthritis

Completed

Conditions studied: Rheumatoid Arthritis

In brief

The purpose of this study is to learn how different types of medicines may improve disease activity in people with rheumatoid arthritis (RA). RA is a kind of joint disease that causes pain and swelling. The study will look at data from a large, US-based group of RA patients who have taken the below medicines: * Tofacitinib * Abatacept * Tocilizumab or sarilumab The study will compare clinical disease activity scores of patients on the different medicines taken. The study will also decide whether some patient traits or disease factors play a role in how medicines may improve disease activity.
