A Comparison of 122-0551 Foam Versus Vehicle Foam in Subjects With Plaque Psoriasis

A Multicenter, Randomized, Double-Blind, Parallel Group Comparison of 122-0551 Foam Versus Vehicle Foam in Subjects With Plaque Psoriasis

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.

Inclusion Criteria:

• 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 an Investigator's Global Assessment (IGA) score of at least three (moderate) at study start.

Exclusion Criteria:

• 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.
• Subject has used any systemic biologic therapy (i.e., FDA-approved or experimental therapy) within five half-lives of the biologic prior to study start.
