Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

3. Patients with 20 to 100 inflammatory lesions (papules, pustules, and nodules) on the face excluding lesions on the nose and in the peri-ocular area.
4. Patients with up to 200 noninflammatory lesions (open and closed comedones) on the face.
5. Patients with no more than 2 nodular lesions on the face.
6. Patients who are surgically sterile, postmenopausal, abstinent, or willing to use an adequate means of contraception including birth control pills, or barrier methods and spermicide for at least 14 days prior to Day 0.

1. Known allergy to MAL, to a similar PDT compound, or to excipients of the cream.
2. Participation in other clinical studies either concurrently or within the last 30 days.
3. Patients who have a condition or who are in a situation, which, in the investigator's opinion, may put the patient at risk, may confound the study results, or may interfere with the patient's participation in the study.
4. Clinically significant sensitivity to visible light, or has porphyria or porphyrin sensitivity.
5. Exposure to ultraviolet radiation (UVB phototherapy, sun tanning salons) within the last 30 days.
6. Patients with a washout period for topical treatments for their acne of less than 14 days. Medicated cleansers may be used during the washout period and stopped before the treatment.
