Effect on Orencia (Abatacept) on the Apoptosis of T Cells, B Cells and APC Cells in Rheumatoid Arthritis
- Conditions
- Apoptotic DNA DamageRheumatoid ArthritisT-cell Lymphocytosis
- Interventions
- Other: Group 2 (DMARDS treated group)Drug: Group 1 or Orencia treated group
- Registration Number
- NCT01717846
- Lead Sponsor
- University of California, Los Angeles
- Brief Summary
This proposal will test the hypothesis that Orencia affects apoptosis and apoptosis related genes/biomarkers in vivo in rheumatoid arthritis (RA) patients.
- 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.

- Arm && Interventions
Group Intervention Description Arm 2 or group 2 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. Arm 1 Group 1 or Orencia treated group 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.
- Primary Outcome Measures
Name Time Method 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 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
