Clinical Trial Summary

Psoriasis and atopic dermatitis are chronic inflammatory disease that account for a significant amount of patients in most dermatological practices. Topical corticosteroid agents are often prescribed for treatment of both these conditions, especially when they are localized rather than wide spread. The development of resistance to treatment is termed tachyphylaxis. Poor adherence, rather than down regulation of receptors, may be the primary cause of tachyphylaxis to topical corticosteroids. The primary objective of the study is to determine, under conditions designed to assure good adherence, whether topical 0.25% desoximetasone spray improves clinical outcomes in patients who have resistant inflammatory skin disease defined by failure of previous topical steroid treatment.

Description:

Psoriasis and atopic dermatitis are chronic inflammatory disease that account for a significant amount of patients in most dermatological practices. Topical corticosteroid agents are often prescribed for treatment of both these conditions, especially when they are localized rather than wide spread. Prolonged treatment with corticosteroids occasionally results in resistance to treatment. The development of resistance to treatment is termed tachyphylaxis. Tachyphylaxis has been thought to be a result of down regulation of target receptors, resulting is a decreased metabolic effect of the compound.

Poor adherence, rather than down regulation of receptors, may be the primary cause of tachyphylaxis to topical corticosteroids. Patients' use of topical medications decrease over time. Topical spray vehicles have become increasingly more popular because of their rapid application and ease of use. Desoximetasone 0.25% spray is a well-tolerated, FDA approved, potent topical corticosteroid that rapidly and successfully treats inflammatory skin diseases.

Lots of treatment options exist for psoriasis; however, some patients do not get better using these medications. These patients are said to have resistant disease. In this study, we define resistant disease by failure of previous topical steroid treatment. Poor adherence is a barrier to positive clinical outcomes. Failure to respond to medication may be a result of poor adherence rather than resistance to the topical therapy. The purpose of this study is to delineate between the two.

The primary objective of the study is to determine, under conditions designed to assure good adherence, whether topical 0.25% desoximetasone spray improves clinical outcomes in patients who have resistant inflammatory skin disease defined by failure of previous topical steroid treatment.

We propose to enroll 12 subjects with psoriasis and 12 subjects with atopic dermatitis who have "failed" previous topical treatment. Subjects will be required to have body surface area involvement that can be reasonably treated with topical treatment. At the baseline visit, patients will be given Topicort spray and will be shown how to use it. Patients will apply the medication at the initial visit under supervision. Subjects with atopic dermatitis will be treated for 1 week; subjects with psoriasis will be treated for 2 weeks. Visits will take place at baseline, 3 days, 1 week, and in the case of psoriasis, 2 weeks. All subjects enrolled in the study will receive nominal compensation per visit.

To assure good adherence to treatment, patients will be called twice each day, morning and evening, at predetermined times to go over their use of the medication. Disease severity will be measured by EASI (atopic dermatitis)/PASI (psoriasis), Investigator Global Assessment (IGA), and Pruritus Visual Analog Scale (Pruritus VAS). Based on our previous experience, we expect rapid improvement in disease severity measures with good adherence to short term use of highly effective topical treatment. Mean and median changes in the efficacy measures will be reported. In the primary analyses, Wilcoxon signed rank tests will be used to analyze improvements in assessments at end of study compared to baseline.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Investigator Global Assessment- Atopic Dermatitis	Investigator's Global Assessment of atopic dermatitis integrates all lesions for overall score. This measure is commonly used to quantify disease severity and most resembles assessments performed in the clinic setting. Score ranges from '0' = Clear to '5' = Very Severe Disease	1 week
Primary	Investigator Global Assessment- Psoriasis	Investigator's Global Assessment of atopic dermatitis integrates all lesions for overall score. This measure is commonly used to quantify disease severity and most resembles assessments performed in the clinic setting. Score ranges from '0' = Clear to '5' = Very Severe Disease	2 weeks
Secondary	Total Lesion Severity Score- Atopic Dermatitis	The total lesion severity score measures scaling, erythema, and plaque elevation. The score range is 0-15, with higher scores denoting worse outcomes.	1 week
Secondary	Total Lesion Severity Score-Psoriasis	The total lesion severity score measures scaling, erythema, and plaque elevation. The score range is 0-15, with higher scores denoting worse outcomes.	2 weeks
Secondary	Eczema Area and Severity Index- Atopic Dermatitis	Eczema Area and Severity Index (EASI): Disease severity will be assessed by a physician with the Eczema Area and Severity Index (EASI). This measure is commonly used and well validated instrument of eczema severity. It is weighted for area in each of the four body regions (which differs for adults and children under 7) and scores erythema, excoriation, induration/papulation, and lichenification. The total scores range from 0-72. Higher scores represent more severe eczema.	1 week
Secondary	Pruritus Visual Analog Scale- Atopic Dermatitis	The Pruritus VAS is a scale consisting of a 10cm long line and a single question. The left end point represents "no itch" (score of 0) and the right end point the "worst imaginable itch" (score of 10).	1 week
Secondary	Pruritus Visual Analog Scale- Psoriasis	The Pruritus VAS is a scale consisting of a 10cm long line and a single question. The left end point represents "no itch" (score of 0) and the right end point the "worst imaginable itch" (score of 10).	2 weeks
Secondary	Psoriasis Area and Severity Index	The Psoriasis Area Severity Index (PASI) is an index used to express the severity of psoriasis. It combines the severity (erythema, induration and desquamation) and percentage of affected areas (head, arms, trunk, and legs). The severity of three clinical signs (erythema, induration and desquamation) are on a scale from 0 to 4 (from absent to very severe). An area and severity score for each region is calculated by multiplying the area score by the severity score. The score range is 0-72, with higher scores denoting worse outcomes.	2 weeks
