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

A Randomized, Double-Blind, Vehicle-Controlled, Multicenter Study to Assess the Efficacy and Safety of Methyl aminolevulinate hydrochloride (MAL) 16.8% cream (CD06809-41) versus vehicle cream in the treatment of thin and moderately thick, non-hyperkeratotic, non-pigmented actinic keratosis of the face and scalp when using daylight photodynamic therapy (DL-PDT).

This was a randomized, double-blind, vehicle-controlled, multicenter, parallel-group study in adult participants with clinically-confirmed mild to moderate AKs on the face and the balding scalp, to be conducted at approximately 60 clinical sites in the United States. Sites were selected to ensure that diverse daylight conditions represented in the study to understand the effects of latitude, elevation, and climate.

Multicenter Study to Assess the Efficacy and Safety of Methyl Aminolevulinate Hydrochloride (MAL) 16.8% Cream (CD06809-41) Versus Vehicle Cream for Actinic Keratosis of the Face

A Randomized, Double-Blind, Vehicle-Controlled, Multicenter Study to Assess the Efficacy and Safety of Methyl Aminolevulinate Hydrochloride (MAL) 16.8% Cream (CD06809-41) Versus Vehicle Cream in the Treatment of Thin and Moderately Thick, Non-hyperkeratotic, Non-pigmented Actinic Keratosis (AK) of the Face and Scalp When Using Daylight Photodynamic Therapy (DL-PDT)

Complete response was defined as clearance of all AK lesion treated, at week 12 after the last Daylight photodynamic therapy (DL-PDT).

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.

Participants achieving partial response was defined as participants with 75% or greater reduction from baseline in the number of cleared treated lesions, at 12 weeks after the last DL-PDT treatment, comparing MAL cream with vehicle cream.

Galderma R&D

Safety population consisted of all randomized participants who received at least 1 application of study drug.

Participants received two treatment session at least 2 weeks apart. Investigator was to apply a thin layer of methyl aminolevulinate (MAL) hydrochloride 16.8% cream to each lesion during treatment. At 30 minutes after cream application, participants were to go outside in daylight for 2 hours. After this time, the cream was to be removed by investigative site personnel by washing the skin with gentle skin cleanser.
