Full Study Name

Strategy to Prevent the Onset of Clinically-Apparent Rheumatoid Arthritis (ARA08) (IRB no. 42472)


This study focuses on patients who have an abnormal blood marker called anti-cyclic citrullinated peptide (anti-CCP), which is an antibody that indicates an individual may be at increased risk for developing rheumatoid arthritis (RA) in the future. RA is a disease in which the immune system attacks the joints, leading to joint inflammation and damage. The purpose of the study is to determine whether a drug called hydroxychloroquine (HCQ) is safe and effective for the prevention of future onset of RA in individuals who have elevations of anti-CCP.

HCQ is approved by the U.S. Food and Drug Administration (FDA) for the treatment of various conditions, but it is not currently approved for the prevention of RA; its use in this study is investigational. Researchers believe that the use of HCQ in patients who have elevations of anti-CCP without joint inflammation may help prevent the future onset of RA.
