Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: Primary efficacy objective: To show the non-inferior efficacy of Metvix® Natural Day Light Photo Dynamic Therapy (NDL-PDT) versus Metvix® conventional Photo Dynamic Therapy (c-PDT) in Subjects with mild and moderate AKs at Week 12 in terms of percent reduction in lesions count. Primary safety objective: To compare the Subject’s self-assessment of pain of Metvix® NDL-PDT with that of Metvix® c-PDT. ;Secondary Objective: Not Applicable;Primary end point(s): Primary efficacy endpoint(s) The primary efficacy endpoint is the lesion complete response rate, defined as the percentage of pre-existing and treated lesions at baseline that were assessed as clear at Week 12. ;Timepoint(s) of evaluation of this end point: At week 12 | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): Secondary efficacy endpoint(s) - Lesion complete response rate for mild lesions only. - Subject-side complete response rate defined as the percentage of subjects with all treated lesions clear in the corresponding TA, at Week 12. - change in lesion severity - number of new lesion Primary Safety endpoint - subject's self assessment of pain at baseline post-PDT procedures Secondary Safety endpoint - Incidence and severity of Adverse Events - skin aspect of lesion in complete response Other endpoint: weather and light asessment;Timepoint(s) of evaluation of this end point: Secondary efficacy endpoint(s): at week 12 Safety primary endpoint: at Baseline post PDT-procedure Secondary safety endpoint: - adverse event: all along the study - skin aspect at week 12 | — |
