Official title
Analysis of T and B Cell Repertoire Changes and CTLA4 Genetics and Gene Expression to Understand the Mechanisms of Treatment Response to Orencia ® (Abatacept) in Rheumatoid Arthritis
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The condition that will be studied is Rheumatoid Arthritis (RA), and in particular, RA patients with moderate to highly active disease who were prescribed Abatacept (Orencia®) (ABA) by their physician during their setting of care at Hospital for Special Surgery (HSS). This investigator-initiated, prospective, comparative, 3-arm observational study will examine changes in lymphocytes in RA patients starting abatacept compared to RA patients starting TNF inhibitors and to healthy controls. This will help investigators to learn more about the processes that cause joints to swell and hurt. This may also offer clues that might predict which patients will have a good or poor response to these treatments.
