This Phase 3 study has been designed to determine and compare the efficacy and safety of 122-0551 Foam and Vehicle Foam applied twice daily for two weeks in subjects with plaque psoriasis.
Subject has a clinical diagnosis of stable plaque psoriasis involving a minimum of 2% and no more than 12% affected body surface area.

Subject has spontaneously improving or rapidly deteriorating plaque psoriasis. Subject has guttate, pustular, erythrodermic or other non-plaque forms of psoriasis. Subject has a physical condition which, in the investigator's opinion, might impair evaluation of plaque psoriasis, or which exposes the subject to an unacceptable risk by study participation. Subject has used any phototherapy (including laser), photo-chemotherapy or other forms of photo based therapy for the treatment of their psoriasis within 30 days prior to study start. Subject has used any systemic methotrexate, retinoids, systemic corticosteroids [including intralesional, intra-articular, and intramuscular corticosteroids], cyclosporine or analogous products within 90 days prior to study start.
