The objective of this study is to investigate if low doses of prednisone TRT, given at night and, with active drug release at 2 am, are more effective in controlling joint stiffness, and other disease symptoms of rheumatoid arthritis than standard prednisone given in the morning. Treatment duration per patient takes 12 months (the double-blind comparative study takes 3 months; 9 months subsequent open treatment on the TRT-medication).
