Exclusion criteria

• Current diagnosis of unstable forms of psoriasis including guttate, erythrodermic, exfoliative or pustular psoriasis.
• Other inflammatory skin disease that may confound the evaluation of the plaque psoriasis (e.g., atopic dermatitis, contact dermatitis, tinea corporis).
• Presence of pigmentation, extensive scarring, pigmented lesions or sunburn which could interfere with the rating of efficacy parameters.
• History of psoriasis unresponsive to topical treatments.
• History of organ transplant requiring immunosuppression, HIV, or other immunocompromised state.
• Use within 180 days prior to Baseline Visit of biologic treatment for psoriasis (e.g., infliximab, adalimumab, etanercept, ustekinumab, or alefacept).
• Have received treatment for any type of cancer within 5 years of the Baseline Visit except for non-melanoma skin cancer and cervical cancer (in situ) are allowed within 1 year of the Baseline Visit.
• Use within 60 days prior to the Baseline Visit of: 1) immunosuppressive drugs (e.g., tacrolimus, pimecrolimus), 2) systemic antipsoriatic treatment (e.g., methotrexate, cyclosporine, hydroxyurea) or 3) oral retinoids (e.g., acitretin, isotretinoin).
• Use within 30 days prior to the Baseline Visit of: 1) systemic steroids, 2) PUVA therapy, 3) systemic anti-inflammatory agents (e.g., mycophenolate mofetil, sulfasalazine, 6-thioguanine), or 4) UVB therapy. Note: Inhaled, intraocular and intranasal steroids are allowed.
• Use within 14 days prior to the Baseline Visit of: 1) topical antipsoriatic drugs (e.g., salicylic acid, anthralin, coal tar, calcipotriene), 2) topical retinoids (e.g., tazarotene, tretinoin) or 3) topical corticosteroids.
