Exceptions: low-potency corticosteroids (Class 6 or 7; please refer to the Investigators’ Manual) will be allowed as background therapy for treatment of the face, axillae, and groin in accordance with the manufacturers’ suggested usage during the course of the study. Subjects with scalp psoriasis will be permitted to use coal tar shampoo and/or salicylic acid scalp preparations on scalp lesions.
