Clinical Trial Summary

The primary objective of this study will be to evaluate the efficacy of topical ALT-2074 applied twice daily for 28 days for treatment of chronic plaque psoriasis in adult subjects.

The secondary objective will be to evaluate the safety of topical ALT-2074 applied twice daily for 28 days for treatment of chronic plaque psoriasis in adult subjects.

Tertiary objectives will be to provide visual documentation of the improvement of psoriatic plaques treated with ALT-2074 using digital photography, and to determine the extent of systemic absorption of topically applied ALT-2074 based on a pharmacokinetic measurement of blood concentration.

3. In otherwise good general health and free of any disease or physical condition which might impair evaluation of plaque psoriasis.

4. Plaque psoriasis treatable area <10% BSA. (Subject palm size is equivalent to 1% of BSA.)

5. Have 2 well-matched plaques (target plaques) of approximately 3 to 8 cm by 3 to 8 cm in size in areas on the right and left or front and back, at sites other than the knees, below the knees, elbows, head, face, scalp, palms, and intertriginous areas.

6. A Combined Psoriasis Severity Score (CPSS) > 6 for each target plaque at Visit 1.

7. Willing to avoid prolonged exposure of the treatment area to ultraviolet radiation (natural and artificial) for the duration of the study.

8. Able to understand and willing to comply with all study requirements, particularly the regimen for administration of study drug.

9. Able to understand and willing to sign the Informed Consent Form.

Exclusion Criteria:

Any subject who meets any of the following criteria will not qualify for entry into the study:

1. Women who are pregnant, lactating, planning to become pregnant, or women of child-bearing potential who have not successfully been using the same medically acceptable contraceptive methods over the previous 3 months, eg, oral contraceptive agents, intrauterine device (IUD), and barrier method plus spermicide.

2. Clinical diagnosis of guttate, pustular, erythrodermic, or other non-plaque forms of psoriasis.

3. Use of emollients or moisturizers on areas to be treated within 24 hours prior to Visits 1 or 2.

4. Use of topical antipsoriatic therapy (including topical retinoids, corticosteroids, or vitamin D analogs) on the areas to be treated within 2 weeks prior to Visit 2.

5. Received systemic immunomodulatory therapy to treat psoriasis (eg, methotrexate, cyclosporine, alefacept, etanercept, infliximab, efalizumab, adalimumab) within 12 weeks prior to Visit 2.

6. Received phototherapy (including laser), photochemotherapy, or systemic psoriasis therapy (eg, systemic corticosteroids, retinoids such as acitretin) within 4 weeks prior to Visit 2.

7. Recent history (within past 12 months) of alcohol or substance abuse. Alcohol abuse will be defined as >14 drinks per week (1 drink = 12 oz beer, 4 oz wine, or 1.5 oz distilled spirits).

8. History of noncompliance to medical regimens or unwilling to comply with the study protocol.

9. Participation in an investigational drug study within 30 days prior to Visit 2.

10. Serious or unstable medical or psychological conditions that in the opinion of the Investigator would compromise the subject's safety or successful participation in the study.
