               2. Immunosuppressive therapies for 4 weeks prior to study entry

               3. Methotrexate, acitretin, or cyclosporine for 4 weeks prior to study entry

               4. Biologic therapies for 3 months prior to study entry.

          -  Concomitant condition requiring treatment with moderate to high dose steroids in the
             12 weeks prior to screening.

          -  Viral, fungal, or bacterial skin infection.
