Rheumatoid arthritis (RA) is a chronic disease that leads to inflammation and progressive joint damage. RA is a systemic inflammatory autoimmune disorder affecting almost 1% of the United States population. Current therapies target the immune system early in the disease process before joint damage occurs, and include drugs such as methotrexate (MTX) and tumor necrosis factor (TNF)-blocking agents. The primary purpose of this study is to determine the effectiveness of two TNF inhibitors, etanercept and adalimumab, on memory B lymphocytes (B-cells) in the peripheral blood of participants with RA. Additionally, there are 4 optional sub-studies as part of the trial: - B-Cell Kinetic Sub-Study to look at changes in B-cell subsets over time and how quickly reductions in B-cell memory occur - Vaccine Response Sub-Study to assess B cell memory in response to immunization with hepatitis B,-hepatitis A, and diphtheria/tetanus vaccines, and to determine whether T-cell vaccine responses are altered with TNF blockade - Tonsil Biopsy Sub-Study to evaluate how TNF blockade affects memory B-cells in the tonsil dendritic cells and germinal cells - Synovial Biopsy Sub-Study to evaluate how TNF blockade affects changes in memory B-cells in lymphoid tissue.

---|---|---|---|---|
Primary | Percentage of CD27+ Switched Memory B Cells at Week 12 | Analysis of the steady state composition of the B cell compartment were performed using ex-vivo multicolor flow cytometry on Ficoll isolated peripheral blood mononuclear cells (PBMCs). CD27+ switched memory B cells are a subset of B cells and are assessed by flow cytometry. CD27+ switched memory B cells are expressed as a percent of B cells. Lower CD27+ memory B cells indicate a decrease in the generation of B cell memory which may be caused by blocking lymphotoxin (LT) and tumor necrosis factor (TNF) signaling. | Week 12 | |
Secondary | Percentage of Participants Fulfilling DAS-28-CRP "Good or Moderate Response" Criteria at Week 12 | Good responders: change in DAS28-CRP (Baseline-Week12) > 1.2 and Week 12 DAS-CRP score was <\= 3.2. If the conditions for non-response* or good response were not met, the DAS28-CRP response was considered moderate.
