All patients will continue to taper their prednisone dose until it is stopped. Methotrexate will continue for 2 years. Patients whose disease remains in remission at this time will decrease the methotrexate dose. If there is no active disease when both prednisone and methotrexate have been stopped, no further treatment will be given. If disease recurs at a later time, treatment will be reinstituted. The treatment will be determined by the severity of disease, other medical conditions, and history of side effects. Patients not randomized to daclizumab who relapse while still taking methotrexate may be offered re-treatment with daclizumab.
