4. Subjects with an Investigator's Global Assessment (IGA) of disease severity of at least moderate severity (score ≥ 3) as an overall assessment.
5. Subjects with a minimum plaque elevation of at least moderate severity (PASI grade ≥ 3) at the target lesion site.
6. If females of childbearing potential, the subject must have a negative urine pregnancy test, and must have been using an acceptable form of birth control for at least two months prior to Screening and are willing to continue birth control throughout the study.
7. Subjects must be willing and able to understand and comply with the requirements of the study, apply the study medication as instructed, return for the required treatment period visits, comply with therapy prohibitions, and be able to complete the study.
8. Subjects must be in good health, as confirmed by medical history and physical exam, and free from any clinically significant disease/condition, other than plaque psoriasis, that might interfere with the study evaluations.

3. Subjects who have a history of psoriasis unresponsive to topical treatments.
4. Subjects who have a history of a disorder that may interfere with the evaluation of plaque psoriasis (e.g., atopic dermatitis, contact dermatitis, tinea corporis, cutaneous lymphoma, etc.).
5. Presence of pigmentation, extensive scarring, or pigmented lesions in the treatment areas, which could interfere with the rating of efficacy parameters.
6. Subjects with unstable medical disorders, life-threatening disease, or current malignancies.
7. Subjects with clinically significant ECG or laboratory abnormalities at Screening (as determined by the Investigator).
8. Subjects who are immunosuppressed.
9. Subjects who have a history of allergy or a known hypersensitivity to any component of the study medication.

12. Subjects who have been treated with biologic therapy other than etanercept within 8 weeks prior to study entry. Vaccines will not be considered an exclusionary biologic treatment.
13. Subjects who have been treated with any topical anti-psoriatic (e.g., salicylic acid, anthralin, tar, etc.,) any topical corticosteroid medications, topical retinoids (e.g., tazarotene, tretinoin), topical Vitamin D analogs (e.g., calcipotriene), topical immunosuppressants (e.g., tacrolimus, pimecrolimus) within 2 weeks prior to study entry.
