| Main Objective: Primary outcome measure: treatment success (i.e. the proportion of patients with =75% lesion reduction in the number of AK lesions counted at baseline in the treatment area) 12 months post treatment; Secondary Objective: - Partial response (proportion of participants at 12 months post treatment with 50-75% reduction in number of AK lesions) - Treatment failure (proportion of participants at 12 months post treatment with <50% reduction in number of AK lesions) - Complete lesion clearance (proportion of lesions with 100% clearance in all treated patients per study arm) - Partial lesion clearance (proportion of lesions with =75% clearance in all treated patients per study arm) - Decrease in number AK from baseline per patient - Number of SCC’s developing in the treatment area, during study follow-up, and long-term follow-up. - Healthcare/treatment costs - Side effects - Patient satisfaction - Cosmetic outcome - Treatment compliance ;Primary end point(s): Primary endpoint: treatment success (i.e. the proportion of patients with =75% lesion reduction in the number of AK lesions counted at baseline in the treatment area) 12 months post treatment;Timepoint(s) of evaluation of this end point: 12 months post-treatment | — |
