Primary Outcome Measures:
  • To measure the change in apoptosis of T cells, B cells and antigen presenting (APC) cells in Rheumatoid Arthritis between the baseline, 3 months and at 6 months time points [ Time Frame: Base line, 3 and 6 months ]
    To determine the effect of Abatacept in the apoptosis of T cells, B cells and antigen presenting cells (APC) in RA patients at baseline, 3 months and 6 months.


Secondary Outcome Measures:
  • To measure the change in disease activity score (DAS28) between the baseline, 3 months and 6 months time points [ Time Frame: Baseline, 3 and 6 months ]
    To measure the changes in disease activity score joint count (DAS28/ESR)


Other Outcome Measures:
  • To measure the change in clinical disease activity index between base line, at 3 months and 6 months time points. [ Time Frame: Baseline, 3 and 6 months ]
    To measure the Clinical Disease Activity Index (CDAI), and Health Assessment Questionnaire (HAQ)


Enrollment: 0
Study Start Date: December 2012
Estimated Study Completion Date: November 2014
Estimated Primary Completion Date: November 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Arm 1
Orencia Group is for RA patients who have not received any other biologic treatment, including abatacept previously, and whose doctor has determined that it is appropriate to treat their RA with Abatacept. If you are in Group 1, you will receive the study drug, Abatacept, given in an intravenous (IV - injected into a vein) as well as subcutaneous form. Abatacept, given in an intravenous injection is approved by the FDA for the treatment of RA.
Drug: Group 1 or Orencia treated group
Group 1 subjects will be given subcutaneous abatacept, 125 mg once a week upto 6 months.
Other Name: Abatacept
Arm 2 or group 2
Arm 2 or Group 2 is for RA patients who are being treated wth non-biologic DMARDS who, with their doctor, have decided that they will not be receiving treatment with Abatacept in the next six months. These patients will not receive the study drug abatacept.
Other: Group 2 (DMARDS treated group)
Arm 2 or Group 2 is for RA patients who are being treated wth non-biologic DMARDS who, with their doctor, have decided that they will not be receiving treatment with Abatacept in the next six months. These patients will not receive the study drug abatacept.
Other Name: Arm 2 or group 2

Detailed Description:

Orencia may regulate apoptosis and apoptosis related genes in vivo in rheumatoid arthritis (RA) patient's cells. To date, no studies have been performed to evaluate the effect of Orencia on apoptosis in RA patients.

Primary: To determine the effect of Abatacept in the apoptosis of T cells, B cells and antigen presenting cells (APC) in RA patients at baseline, 3 months and 6 months.

Secondary: To evaluate the association between the changes in apoptosis to changes in disease activity measures (DAS28/ESR) over 6 months of treatment with subcutaneous injection of abatacept.
