The purpose of this study is to determine if the use of sub-cutaneous (SC) abatacept provides any structural benefit in patients with rheumatoid arthritis who have failed prior use of TNF therapy.

Primary Outcome Measures:
  • Number of Participants With an Improvement in Bone Edema/Osteitis on Low-field MRI in Rheumatoid Arthritis Patients on Weekly SC Abatacept in Combination With Methotrexate Over a 12-month Period. [ Time Frame: MRIs at Baseline and Week 48 ]
    bone edema/osteitis using low-field MRI analysis of 25 anatomical locations in the wrist and hand and scoring the volume of the original articular bone in 0.5 increments from 0-3, with each increment in the scale representing 33% of the volume of the peripheral 1 cm of original (eroded + residual) articular bone.

Secondary Outcome Measures:
  • Patients With an Improvement in DAS Score Were Considered Responders at Week 48 [ Time Frame: The DAS 28 score will be performed at baseline and 48 ]
    Patient with a positive change in DAS score were considered responders . The DAS score is calculated using the number of tender and swollen joints based upon a 28 joint count, the ESR in mm/hr., and the physician global score

  • To Measure the Change From Baseline in Patient DAS 28 Scores at Baseline and Weeks 12, 24 [ Time Frame: Patient DAS 28 scores will be measured at baseline and weeks 12, 24, 48 and disease activity will be recorded at Week 48 ]
    DAS 28> 5.1=high disease activity DAS28 <3.2=low disease activity DAS28 <2.6=remission Criteria used in formula are number of tender joints based upon 28 joints, number of swollen joints based on 28 joints, ESR in mm/hr and patient global health core based on 0-10 mm

  • the Clinical Outcomes Measurements (American College of Rheumatology Activity Scoring, Health Assessment The Number of Patients With a Clinical Response at Week 24 and 48 [ Time Frame: week 24 and Week 48 ]
    Patient with a positive change in DAS score were considered responders . The DAS score is calculated using the number of tender and swollen joints based upon a 28 joint count, the ESR in mm/hr., and the physician global score (1-10 cm). Total maximum score was at high disease activity at baseline.

  • Number of Patients With Adverse Events [ Time Frame: all adverse events will be captured from Day 1 up to 52 weeks ]
    site will report the number of patients with adverse envents from Day 1 up to 52 weeks

Enrollment: 34
Actual Study Start Date: June 2011
Study Completion Date: April 2014
Primary Completion Date: January 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
open label use of abatacept for 12 months
Biological: abatacept
Abatacept administered SC weekly at 125 mg dose
Other Name: orencia

Detailed Description:
Results in the literature suggest the structural benefits of intravenous (IV) abatacept as measured by high and low field MRI and X-ray in patients with rheumatoid arthritis who have previously failed clinical treatment with TNF agents. This study attempts to measure the structural benefits of SC abatacept in a similar cohort of patients while at the same time comparing the structural findings with clinical outcome measurements as collected at corresponding time points with an automated patient and physician disease activity scoring system of 28 joints (DAS28).
