General information about the trial
|
|||
Main objective of the trial |
The primary objective of our research is to determine the effect of anti-TNF-alpha treatment on the levels of a cell type of the immune system, called Th17 cells and their product, IL-17 in blood samples and joint biopsies from patients with rheumatoid arthritis at different time points during treatment and how these changes correlate with parameters of systemic and local disease activity.
