Measure
MAL 16.8% Cream
Participants received two treatment session at least 2 weeks apart. Investigator applied a thin layer of methyl aminolevulinate (MAL) hydrochloride 16.8% cream to each lesion during treatment. At 30 minutes after cream application, participants went outside in daylight for 2 hours (Daylight photodynamic therapy \[DL-PDT\]). After this time, the cream was removed by investigative site personnel by washing the skin with gentle skin cleanser.
MAL Vehicle Cream
Participants received two treatment session at least 2 weeks apart. Investigator applied a thin layer of vehicle cream to each lesion during treatment. At 30 minutes after cream application, participants went outside in daylight for 2 hours (DL-PDT). After this time, the cream was removed by investigative site personnel by washing the skin with gentle skin cleanser.

SECONDARY outcome

Timeframe: Baseline, Week 12

Population: ITT analysis population included all participants randomized in the study.

Lesion complete response was defined as percent reduction from baseline in the number of cleared treated lesions, at 12 weeks after the last DL-PDT treatment. This outcome measure was analyzed as an intra-individual comparison between MAL cream and Vehicle cream.
