Study Description

Brief Summary:

This multicenter study will be divided into 2 phases. The first phase will be an open label, dose-escalation phase, while the second will be a blinded, randomized, vehicle-controlled, parallel-group, dose-response phase. The second phase will only start if the first phase succeeds in establishing well tolerated dose(s). Patients with moderate to severe acne vulgaris in the face will be included.The results from part 2 has been presented in the result section.

Condition or disease	Intervention/treatment	Phase
Acne Vulgaris	Drug: Methyl aminolevulinate (MAL) PDT	Phase 2

Detailed Description:

For the second part: All patients will receive 4 PDT sessions 2 weeks apart using a light dose of 37 J/cm2. One treatment group will receive vehicle cream, while the other 2 groups will receive MAL cream with a concentration of 40 mg/g and 80 mg/g, respectively. The MAL and vehicle cream will be applied in a thin layer on clean skin and left for 1.5 hours under occlusion before illumination.
