A Study to Perform Synovial Biopsies on Patients with Rheumatoid Arthritis


About this study

The purpose of this study is to get synovial tissue from patients with rheumatoid arthritis by minimally invasive ultrasound guided biopsy, for the purpose of identifying the processes that are responsible for the cause of the disease. 

Participation eligibility

Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate.
