Phase 3b Study of Metvix NDL-PDT Versus Metvix c-PDT in Subjects With Actinic Keratoses (COMET2)

February 16, 2021 updated by: Galderma R&D

Multi-centre, Randomized, Investigator-blind, Intra-individual Active and Vehicle-controlled Study, Comparing Metvix Natural Daylight Photodynamic Therapy Versus Metvix Conventional Photodynamic Therapy in Subjects With Actinic Keratosis

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.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Percentage (%) Change From Baseline in Total Lesion Complete Response at Week 12 in Group 1
Time Frame: Baseline, Week 12
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).
