Effect on Orencia (Abatacept) on the Apoptosis of T Cells, B Cells and APC Cells in Rheumatoid Arthritis

Phase 4
Withdrawn
Conditions
Apoptotic DNA Damage
Rheumatoid Arthritis
T-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
GroupInterventionDescription
Arm 2 or group 2Group 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 1Group 1 or Orencia treated groupOrencia 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.
