A Study of Immune Cells in Patients With Rheumatoid Arthritis During Different Types of Anti-TNF Alpha Treatments (Study P05521)

Rheumatoid Arthritis Clinical Trial

Official title: Whole Human Genome Oligo Microarray Analysis of the Peripheral Blood Mononuclear Cells of Patients With Rheumatoid Arthritis During Different Forms of Anti-Tumor Necrosis-Alpha Treatments.

Status Withdrawn

Clinical Trial Summary

This 14-week study will observe the gene expression of certain immune cells in patients with rheumatoid arthritis who receive etanercept, infliximab, and adalimumab. Patients at the National Institute of Rheumatology and Physiotherapy, Budapest, who are already scheduled to receive an anti-TNF agent will be asked to participate in this study. Patients will receive their treatment (etanercept, infliximab, or adalimumab) as scheduled, and have blood samples collected during the study and analyzed by the laboratory. Patient's response to their treatment will also be studied based on x-rays and other examinations.

Clinical Trial Description

Only patients who - regardless of this study - are scheduled and permitted to receive anti-TNF-alpha treatment because of their RA will be asked to participate. No patient will be recruited only for the sake of the study. The prescribing physicians will not be influenced by the study as to what form of anti-TNF-alpha therapy they should select. ;
