Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: To compare the patient complete response rate of Metvix® PDT to that of vehicle PDT 3 months after last treatment in patients with multiple AK lesions on the face and/or scalp. ;Secondary Objective: - To compare local AEs (treatment site AEs) between Metvix® PDT and vehicle PDT. - To compare lesion complete response rate between Metvix® PDT and vehicle PDT 3 months after last treatment ;Primary end point(s): The primary efficacy end-point will be patient complete response rate, determined by clinical assessment (visual inspection and palpation) 3 months after last treatment. A patient will be considered a complete responder if all treated lesions show complete clinical response, as assessed by visual inspection and palpation. | — |
