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

18 de março de 2015 atualizado por: 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).

DAS 28 C Reactive Protein (CRP) Score - Mean Change From Baseline
Prazo: 6 months, 12 months, 24 months
The DAS 28 (CRP) is a composite of 4 variables: 28 tender joint count, 28 swollen joint count, CRP, and subject assessment of disease activity measure on a VAS of 100 mm. Change from Baseline=postbaseline score-baseline score; a lower value signifies improvement.
6 months, 12 months, 24 months
Number of Participants With a DAS 28 (CRP) Score of ≤3.2 (Low Disease Activity) or <2.6 (in Remission)
Prazo: 6 months, 12 months, 24 months
The DAS 28 (CRP) is a composite of 4 variables: tender joint count, swollen joint count, CRP, and subject assessment of disease activity measure on a VAS of 100 mm. Scores for disease activity are defined as low (≤ 3.2) and in remission (< 2.6).
6 months, 12 months, 24 months
Number of Subjects With Health Assessment Questionnaire (HAQ) Disability Index Response
Prazo: 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.
6 months, 12 months, 24 months
Overall Safety - Adverse Events (AEs), Serious AEs, and Deaths
Prazo: Throughout the treatment period (6 months)
AEs were monitored at all scheduled visits of the study drug treatment and observation periods and at the follow-up visits performed 28, 56, and 85 days after the last infusion of study medication for participants who were withdrawn prematurely
Throughout the treatment period (6 months)
Number of Participants With Positive Responses for Serum Levels of Abatacept-specific Antibodies
Prazo: Up to 12 months
Immunogenicity, as measured by the number of positive repsonses for serum levels of abatacept-specific antibodies measured by enzyme-linked immunosorbent assays (ELISA). Postive response for whole molecule assessment was a value of > 400 and for tip assessment was ≥25.
Up to 12 months
