Study of Abatacept Versus Placebo to Assess the Prevention of Rheumatoid Arthritis (RA) in Adult Patients

2015年3月18日 更新者: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).

Number of Subjects With Health Assessment Questionnaire (HAQ) Disability Index Response
大体时间:6 months, 12 months, 24 months
This questionnaire includes 20 questions assessing physical function in 8 domains. The questions are evaluated on a 4-point scale: 0=without any difficulty, 1=with some difficulty, 2=with much difficulty and 3=unable to do. Higher scores indicate greater dysfunction. HAQ response =improvement of at least 0.3 units from baseline.

Throughout the treatment period (6 months)
Number of Participants With Positive Responses for Serum Levels of Abatacept-specific Antibodies
