Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Percent change from baseline (predose day 1) to 18-week period Target Lesion Severity score (TLS) of lesions | Target lesions will be evaluated for 3 components: erythema, induration, and scaling. Each component will be given a score using the following scale: 0=none, 1=slight, 2=moderate, 3=marked, 4=very marked. The Target Lesion Severity (TLS) score is calculated as a sum of the 3 components. | Subjects will have study visits at screening- visit 1, randomization - visit 2, after 6 weeks treatment - visit 3, 12 weeks treatment -end of treatment - visit 4 and week 16 - follow up visit 5. |
