Trial Outcomes & Findings for Phase 3b Study of Metvix NDL-PDT Versus Metvix c-PDT in Subjects With Actinic Keratoses (NCT NCT01821391)

NCT ID: NCT01821391

Last Updated: 2021-02-18

Results Overview

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).

PRIMARY outcome

Timeframe: Baseline, Week 12

Population: Intent-to-treat (ITT) population included entire population enrolled and randomized. ITT analysis imputed missing data using a worst case approach and considered the lesions with missed lesion response assessment as not responded (ITT/Worst-case) lesions.

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).
