The investigators are looking for patients with rheumatoid arthritis (RA) with an inadequate response to tumor necrosis factor inhibitor (TNFi) and another biologic disease modifying anti-rheumatic drug (bDMARD) or small molecule approved for treating RA. The investigators are conducting this research to learn more about RA and the genetic patterns associated with patients whose RA cannot be well controlled with most RA treatments. Investigators anticipate that these patients will differ from classic RA patients in their biomarker and genetic composition and that they represent a mixed group of individuals who may be similar in ways that are not currently being measured.
The investigators are interested in enrolling patients with rheumatoid arthritis (RA) who had a difficult time getting their disease under control even after trying multiple RA therapies. The investigators believe that there may be common patterns in the genes of this group of RA patients compared to those with more textbook RA. Understanding genetic factors can help doctors to know in advance who may not respond to conventional therapies and start with treatments that work. Learning about underlying genes that influence treatment may help the investigators to identify new targets for therapy, to ultimately improve the lives of patients with RA and inflammatory arthritis.
