Topical NF-kappaB Decoy in the Treatment of Atopic Dermatitis

This is a randomized, double-blind, placebo-controlled, parallel-group, dose-ranging study to evaluate the safety of repeated application of three concentrations of NF-kappaB Decoy in approximately 75 subjects with mild-to-moderate atopic dermatitis. The face, hands, feet, scalp, or groin may NOT be treated.

Other treatment agents are currently available for atopic dermatitis but present significant potential side effects (topical steroids) or are potent immunosuppressives (topical calcineurin inhibitors) with pending longer-term safety data.

NF-kappaB Decoy is a double-stranded deoxyribonucleic acid (DNA) oligodeoxynucleotide that mimics the NF-kappaB binding sequence on the chromosomal DNA, thereby inhibiting the production of the inflammatory response triggered by NF-kappaB. This mechanism of action presents a unique treatment modality.

A comprehensive series of nonclinical data have produced promising results.

• If receiving antihistamines, are on a stabilized dose, and expect to maintain this dose throughout the study
• Are females or males of reproductive potential who are compliant in using adequate birth control or are females or males not of reproductive potential

Exclusion criteria

• Have concomitant dermatologic or medical condition(s) which may interfere with the investigator's ability to evaluate the subject's response to the study drug

• Have any clinically significant abnormal clinical laboratory test results at Screening
• Have a history of malignancy not in remission for at least 5 years excluding basal cell carcinoma and nonperiorificial squamous cell carcinoma of the skin
• Have an active intercurrent infection
• Have applied any topical medication (including corticosteroid, calcineurin inhibitor, topical H1 and H2 antihistamines, topical antimicrobials, other medicated topical agents) or herbal preparation to the area selected for treatment within 1 week of the Day 1 visit; have used any systemic antibiotic within 1 week prior to the Day 1 visit; have used any systemic treatment for atopic dermatitis (including systemic corticosteroids, nonsteroidal immunosuppressants, or treatment with light) within 4 weeks prior to the Day 1 visit; have used an investigational drug for any reason within 4 weeks of the Day 1 visit; have used intranasal and/or inhaled corticosteroids at doses > 2 mg prednisone or equivalent per day within 4 weeks of the Day 1 visit; or have used immunosuppressive or immunomodulating drugs such as etanercept, alefacept, or infliximab within 16 weeks prior to Day 1
• Have a history of hypersensitivity or allergic reactions to parabens or any other ingredient in the vehicle formulation
• If female, are pregnant or lactating, or intend to become pregnant during the study period
• If male, have a female partner who is pregnant or lactating, or intends to become pregnant during the study period
• Have any reason which, in the opinion of the investigator, interferes with the ability of the subject to participate in or complete the trial, or which places the subject at undue risk
