Photodynamic Therapy (PDT) With Methyl Aminolevulinate (MAL) Cream in Patients With Skin Type V or IV With Acne Vulgaris

A Blinded, Randomized, Intra-individual, Vehicle-controlled and Multi-centre Study of Photodynamic Therapy With MAL Cream in Patients With Skin Type V or VI With Acne Vulgaris

In this multicenter study, patients with dark skin and acne vulgaris will be included. The patients will receive treatment with MAL PDT and placebo PDT.

Study Overview

• Status: Completed
• Conditions: Acne Vulgaris
• Intervention / Treatment: Drug: Methyl aminolevulinate (MAL) PDT

Detailed Description

The treatment period started within 2 weeks of the study screen. Patients received two treatments (MAL PDT and vehicle PDT) to each of the treatment areas, 2 weeks apart, and were followed-up 4 weeks after last treatment. The total duration of the study was 6-8 weeks.

Methyl aminolevulinate 80 mg/g cream (MAL cream 8%)and vehicle was applied for 1.5 hours before illumination (Aktilite® CL128), total light dose 37 J/cm2
