The objective of this study is to estimate the efficacy of Cloderm Cream for topical
treatment of moderate plaque psoriasis over 28 days using current standards for evaluation.

Inclusion Criteria:

1. Subject understands the study procedures and agrees to participate by giving written
informed consent.

2. Subjects must be at least 18 years of age.

3. Subjects must present with a clinical diagnosis of stable (at least 3 months)
plaque-type psoriasis.

4. Subjects with psoriasis involving 2 to 20% BSA, not including the face, scalp and
intertriginous areas.

5. Subjects must have an IGA Grade of 3 at the Baseline Visit.

6. Female subjects of childbearing potential must have a negative urine pregnancy test
result at Baseline (Visit 2) (test will have a sensitivity of at least 25mIU/ml for
human chorionic gonadotropin) and practice a reliable method of contraception or
remain sexually inactive throughout the study.

All women of childbearing potential must be willing to undergo a urine pregnancy test
at Visit 2 (Day 0), at Visit 4 (Day 14), and at Visit 5 (Day 28).

7. Subjects must be in good general health as determined by the investigator and
supported by the medical history and normal or not clinically significant abnormal
vital signs (blood pressure and pulse).

Exclusion Criteria:

1. Current diagnosis of unstable forms of psoriasis including guttate, erythrodermic,
exfoliative or pustular psoriasis.

2. Other inflammatory skin disease that may confound the evaluation of the plaque
psoriasis (e.g., atopic dermatitis, contact dermatitis, tinea corporis).

3. Presence of pigmentation, extensive scarring, pigmented lesions or sunburn which
could interfere with the rating of efficacy parameters.

4. History of psoriasis unresponsive to topical treatments.

5. History of organ transplant requiring immunosuppression, HIV, or other
immunocompromised state.

6. Use within 180 days prior to Baseline Visit of biologic treatment for psoriasis
(e.g., infliximab, adalimumab, etanercept, ustekinumab, or alefacept).

7. 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.

8. 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).

9. 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

10. 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.

11. Subjects with known hypersensitivity to clocortolone pivalate or any component of
Cloderm Cream.

12. Subjects who have participated in a study of an investigational drug 60 days prior to
the Baseline Visit.

13. Subjects unable to comply with study requirements.

14. Female subjects who are pregnant (or planning to become pregnant) or breast-feeding.
