Hydrogel Patch for the Treatment of Eczema
The primary objective of this clinical study is to determine whether occlusion of triamcinolone 0.1% cream (TAC) with hydrogel patch improves its efficacy in treating eczema. A secondary objective is to determine whether eczema improves under occlusion with hydrogel patch alone, without TAC.

- Change in Disease Severity: Percent Change in Mean EASI Score [ Time Frame: Baseline, 6 weeks ] [ Designated as safety issue: No ]Percent change in mean EASI score week 0 to week 6: Each lesion was scored using a 12-point modified Eczema Area and Severity Index (EASI) at baseline and 2 weeks after the 4-week treatment period (week6). An experienced evaluator assessed each lesion on the severity of 4 domains, with higher scores indicating more severity: 1) intensity of redness (erythema), 2) thickness (induration, papulation, oedema), 3) scratching (excoriation) and 4) lichenification (lined skin) as as none (0), mild (1), moderate (2) and severe (3). Pictorial and descriptive instructions guided the evaluator in scoring the lesions based on visual appearance.

Experimental: Patch + cream, patch alone, cream alone
This is a single arm study. Each subject will have 3 target lesions; one treated with TAC 0.1% cream and hydrogel patch (occlusion), the second treated with cream alone, and the third treated with occlusion alone.
Device: hydrogel patch
occlusion of eczema with a hydrogel patch composed of an adhesive, thin, flexible, hydrogel layer on an impermeable urethane surface.
Other Names:Drug: Triamcinolone (TAC) 0.1% cream
Triamcinolone Acetonide (triamcinolone acetonide cream) is a topical corticosteroid used as anti-inflammatory and antipruritic agent. Each gram of TAC Cream USP, 0.1% contains 1 mg Triamcinolone Acetonide (triamcinolone acetonide cream) in a cream base consisting of cetyl alcohol, glyceryl monostearate, cetyl esters wax, isopropyl palmitate, polysorbate-60, polysorbate-80, propylene glycol and purified water.
This will be a 6-week, open label, bilaterally-controlled single center study involving 30 subjects age 13 and older with eczema. The primary objective of this clinical study is to determine whether occlusion of triamcinolone 0.1% cream (TAC) used to treat eczema with hydrogel patch improves its efficacy. A secondary objective is to determine whether eczema improves under occlusion with hydrogel patch alone. All subjects will have 3 target lesions of similar severity followed throughout the study. Patients will apply hydrogel patch alone to the first lesion, TAC 0.1% cream to the second lesion, and TAC 0.1% cream occluded by hydrogel patch to the third lesion. All treatments are twice a day for a maximum of 4 weeks or until lesions are cleared. The modified Eczema Area and Severity Index (EASI) score will be used to evaluate each lesion.
