Clinical Trial Summary

This study was to be conducted as a multi-centre, randomized, investigator-blinded, active and vehicle-controlled, intra-individual (split-face/scalp) non-inferiority (regarding efficacy) and superiority (regarding pain) study. The primary purpose of this study is to demonstrate the non-inferiority of NDL-PDT compared to c-PDT in terms of lesion complete response rate.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Percentage (%) Change From Baseline in Total Lesion Complete Response at Week 12 in Group 1	The lesion complete response rate was defined as the percentage of pre-existing and treated lesions at Baseline that were assessed as clear (complete disappearance of the lesion, visually and by palpation) at Week 12. New lesions or the lesions in non-complete response were not not considered in the lesion response assessment. This outcome measure was analyzed as an intra-individual comparison between Metvix NDL-PDT on one side of the face/scalp and Metvix vehicle cream (placebo) c-PDT on the contralateral side (Group I).
