The goal of this study is to enable the study sponsor to assess the impact of a marketed or validated blood test has on physicians' clinical treatment decision making when treating RA patients who have been taking methotrexate.
Ultimately, the blood test will allow treating physicians to modify current methotrexate therapy in partially responding Rheumatoid Arthritis (RA) patients' therapy, on an individualized basis, as a means of improving clinical outcomes.
The study requires a blood sample from RA patients who have been on methotrexate therapy for a minimum of 3 months and are having an inadequate response to therapy. Physicians will then be provided with the results of the test indicating the methotrexate polyglutamate (active metabolites of methotrexate) levels in the patient's red blood cells as a means to help determine whether a patient's exposure to methotrexate has been optimized.
This study is currently enrolling individuals who have an established diagnosis of RA and are receiving methotrexate as part of their therapy. Patients are required to submit a blood sample. There is no cost to volunteers who participate.

Arthritis in children, with onset before 16 years of age. The terms juvenile rheumatoid arthritis (JRA) and juvenile idiopathic arthritis (JIA) refer to classification systems for chronic arthritis in children. Only one subtype of juvenile arthritis (polyarticular-onset, rheumatoid factor-positive) clinically resembles adult rheumatoid arthritis and is considered its childhood equivalent.
Rheumatoid arthritis of children occurring in three major subtypes defined by the symptoms present during the first six months following onset: systemic-onset (Still's Disease, Juvenile-Onset), polyarticular-onset, and pauciarticular-onset. Adult-onset cases of Still's disease (STILL'S DISEASE, ADULT-ONSET) are also known. Only one subtype of juvenile rheumatoid arthritis (polyarticular-onset, rheumatoid factor-positive) clinically resembles adult rheumatoid arthritis and is considered its childhood equivalent.
A variable mixture of the mono- and disodium salts of gold thiomalic acid used mainly for its anti-inflammatory action in the treatment of rheumatoid arthritis. It is most effective in active progressive rheumatoid arthritis and of little or no value in the presence of extensive deformities or in the treatment of other forms of arthritis.
Systemic-onset rheumatoid arthritis in adults. It differs from classical rheumatoid arthritis in that it is more often marked by acute febrile onset, and generalized lymphadenopathy and hepatosplenomegaly are more prominent.
