PARIS, June 13 /CNW/ -- Seven-year rheumatoid arthritis (RA) data from open-label extension studies show that treatment with Abbott’s HUMIRA(R) (adalimumab) resulted in clinical remission among long-standing RA patients when used in combination with methotrexate (MTX). The percentage of patients achieving clinical remission continued to increase after two or more years of continuous treatment with combination therapy. These data were presented at the European League Against Rheumatism (EULAR) annual meeting in Paris.
