3. A clinical diagnosis of mild to moderate atopic dermatitis that has failed to respond adequately to other topical prescription treatments for atopic dermatitis, or subjects for whom the use of those other treatments is deemed inadvisable.

4. A diagnosis of atopic dermatitis for at least 3 months.

5. A baseline Investigator's Global Assessment (IGA) of disease severity of mild or moderate (score of 2 or 3). (See Section 9.6.10 for the scale.)

6. An affected area of atopic dermatitis involvement of at least 5% of the body surface area (BSA) at Visit 2/Day 1 (Baseline), as defined by the criteria of Hanifin and Rajka (1980).

7. Treatment with a bland emollient for at least 7 days prior to Visit 2/Day 1 (Baseline).

8. Agree to adhere to protocol-specified requirements and concomitant therapy restrictions.

9. Willing to avoid constant sun exposure and the use of tanning booths or other UV light sources during participation in the study.

10. In general good health, non-immunocompromised, and free from any clinically significant disease, other than atopic dermatitis, that might interfere with the study evaluations.

11. Willing and able to understand and comply with the requirements of the study, apply the study medication as instructed, return for the required study visits, comply with therapy prohibitions, and complete the study.

12. Female subjects of childbearing potential (excluding women who are surgically sterilized [hysterectomy, bilateral tubal ligation, or bilateral ovariectomy] or have been postmenopausal for at least 1 year) must have a negative urine pregnancy test and must be willing to use a medically accepted method of contraception during the study. The following are considered acceptable methods of birth control for the purpose of this study: oral contraceptives, contraceptive patches, contraceptive implant, vaginal contraceptive, double barrier methods (e.g., condom and spermicide), contraceptive injection (Depo-Provera®), intrauterine device (IUD), hormonal IUD (Mirena®), Essure® permanent birth control, and abstinence with a documented second acceptable method of birth control if the subject becomes sexually active.

Exclusion Criteria

1. Females who are pregnant, breastfeeding, intending to become pregnant during the study, or who do not agree to use an acceptable form of birth control during the study.

2. Active cutaneous bacterial or viral infection in any proposed treatment area at Visit 2/Baseline (e.g., clinically infected atopic dermatitis).

3. Sunburn, extensive scarring, or pigmented lesion(s) in any treatment area at Visit 2/Baseline that would interfere with the study evaluations.

4. History of confounding skin conditions, e.g., psoriasis, rosacea, erythroderma, or ichthyosis.

5. History or presence of Netherton's Syndrome, immunological deficiencies or diseases, HIV, diabetes, malignancy, serious active or recurrent infection, clinically significant severe renal insufficiency, or severe hepatic disorders.

6. Use of any treatment listed in Table 9.1 more recently than the indicated washout period prior to Visit 2/Baseline.

7. Need or intent to continue to use any treatment listed in Table 9.1 during the current study.
