Switching Anti-TNF-Alpha Agents in Rheumatoid Arthritis (RA)
Rheumatoid Arthritis (RA) is a systemic inflammatory autoimmune disorder that leads to inflammation and progressive joint damage affecting 2.5 million people in the United States. The primary purpose of this study is to determine the effectiveness of switching to an alternative Tumor Necrosis Factor (TNF) alpha inhibitor in comparison to continuing treatment with an existing TNF-alpha inhibitor in adults suffering from RA in a setting of inadequate clinical response to etanercept or adalimumab.
Stanford is currently not accepting patients for this trial.
