11. Corticosteroid use from 30 days prior to randomisation until final assessment visit will be exclusionary, with the following exceptions:

1. Oral corticosteroids in low doses (= 10 mg/d prednisone or equivalent) will be allowed if stable for 1-month prior to randomisation. Reduction of dose or use of oral corticosteroids is permissible throughout the study.
