Outcome Measures

Primary Outcomes (1)

  • To compare the number of inflammatory acne lesions according to time on the side with occlusion and the side without occlusion for subjects with facial acne vulgaris exposed to 25 J/cm2 and 37 J/cm2 of red light.

    4 and 12 weeks after last PDT session.

Secondary Outcomes (1)

  • Exposed to 25 J/cm2 and 37 J/cm2 of red light and with and withut occlusion :-Compare number of non-inflammatory acne lesions. -Safety assesment of MAL-PDT. -Evaluate PAP photobleaching.

    At each treatment visit and 2 and 7 days after first PDT treatment visit.

Study Arms (4)

25 J/cm2, with occlusion on right side

ACTIVE COMPARATOR

Subjects will receive MAL cream in a thin layer on both sides of the face (except nose and peri-ocular area) at a concentration of 80 mg/g). Occlusion will be applied to one half of the face. After an incubation time of 90 minutes both sides of the face will be exposed to either 25 J/cm2 of red light starting with the occluded side first.

Drug: MAL

37 J/cm2, with occlusion on right side

ACTIVE COMPARATOR

Subjects will receive MAL cream in a thin layer on both sides of the face (except nose and peri-ocular area) at a concentration of 80 mg/g). Occlusion will be applied to one half of the face. After an incubation time of 90 minutes both sides of the face will be exposed to 37 J/cm2 of red light starting with the occluded side first.

Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Subject willing to use an adequate contraceptive method or is surgically sterile, post menopausal, abstinent or with a same-sex partner.

  • Age 18 or older
  • Capable of giving informed consent
  • Diagnosis of acne vulgaris on the face with at least 10 inflammatory lesions on both sides of the face at screening and day 0
  • Global acne severity assessment score ≥ 3 at the screening and day 0 visit.

You may not qualify if:

  • Allergy to methylaminolevulinate or any component of the vehicle
  • Acne fulminans or conglobata on the face
  • Clinical significant sensitivity to visible light, porphyria or porphyrin sensitivity
  • Use of any topical treatment for acne on the face within the previous 2 weeks before day 0
  • Any use of systemic antibiotics within 1 month prior to day 0 or use of isotretinoin within 1 year prior to Day 0

  • Alcoholism or drug abuse in the past year
  • Any unstable or serious medical condition at the discretion of the investigator
  • Current pregnancy or lactation
  • Use of hormonal contraceptives solely for control of acne
  • Current use of oral contraceptives (unless subject is on a stable dose e.i. at least six months of treatment prior Day 0), testosterone or any other systemic hormonal treatment
  • Any serious dermatological disorder, including malignancies that would either put the subject at risk or interfere with efficacy or safety evaluations
  • Fitzpatrick phototype V or VI (inadequate penetration of red light in dark skin subjects)
  • Subjects with extensive facial hair (e.g. beard) that would either impair red light exposure or interfere with lesion evaluation.
