Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Clearance of AK | 8 weeks | The primary response criterion is the clinical and histological clearance of AK at Day 57. Clinical Clearance will be measured by counting AKs, and histological clearance will be by performing a biopsy (result reported as AK or not AK). |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Complete clearance of AKs in the Selected Treatment Area | 8 weeks | Efficacy in terms of complete clearance of AKs in the STA and histological clearance of pre-identified lesion. AK clearance will be determined by AK count. Clearance of the pre-identified lesion will be assessed by a histopatholgist from a biopsy sample and reported as AK or not AK. |
