Outcomes

Primary Outcomes

Number of Subjects With 'Overall Improvement' for the Target Lesion on the Scalp

'Overall improvement' for the target lesion on the scalp, defined as 'substantial resolution' of clinical signs and/or at least 'moderately improved' in the general change in the lesion. 'Substantial resolution' is defined as a clinical score for thickness and scaliness of 0 and a clinical score for redness of 1 or less in the severity of clinical signs of the lesion.

Time frame: End of Week 4

Secondary Outcomes

Number of Subjects With 'Overall Improvement' for the Target Lesion on the Non-scalp Area of the Body

'Overall Improvement' for the target lesion on the non-scalp area of the body, defined as 'substantial resolution' of clinical signs and/or at least 'moderately improved' in the general change in the lesion. 'Substantial resolution' is defined as a clinical score for thickness and scaliness of 0 and a clinical score for redness of 1 or less in the severity of clinical signs of the lesion.

Time frame: End of Week 4

The Change in the Sum of the Scores (Total Sign Score) for the Severity of the 3 Clinical Signs:Thickness, Scaliness, Redness From Baseline to End of Week 4 (Visit 1-4) for Each Target Lesion.

Severity was recorded for each of the 3 clinical signs according to the 9-point scales\* below. \*intermediate intervals (0.5, 1.5, 2.5, 3.5) serve as mid points between the defined grades. Redness 0=none (no erythema) 1. slight (faint erythema, pink to very light red) 2. mild (definite light red erythema) 3. moderate (dark red erythema) 4. severe (very dark red erythema) Thickness 0=none (no plaque elevation) 1. slight (slight, barely perceptible elevation) 2. mild (definite elevation but not thick) 3. moderate (definite elevation, thick plaque with sharp edge) 4. severe (very thick plaque with sharp edge) Scaliness 0=none (no scaling) 1. slight (sparse, fine scale, lesions only partially covered) 2. mild (coarser scales, most of lesions covered) 3. moderate (entire lesion covered with coarse scales) 4. severe (very thick coarse scales, possibly fissured) Negative change denotes a decrease in the score and therefore a decrease in disease severity.
