Study of Abatacept Versus Placebo to Assess the Prevention of Rheumatoid Arthritis (RA) in Adult Patients
18 mars 2015 mis à jour par: Bristol-Myers Squibb
A Phase II Study of Abatacept Versus Placebo to Assess the Prevention of Rheumatoid Arthritis (RA) in Adult Patients With Undifferentiated Arthritis Who Are at High Risk for the Development of RA
The purpose of this study is to assess if Abatacept given for six months will prevent rheumatoid arthritis (RA) in patients who are at risk for the development of RA in comparison to placebo.
High risk patients are defined as those having a positive laboratory test for anti-cyclic citrullinated peptide (anti-CCP2).
