Outcome Measures

Primary Outcomes (2)

  • Relative change in the number of inflammatory lesions (relative change from baseline) 8 weeks after the last PDT as assessed by investigator.

    Outcome 1 is the relative change in the number of inflammatory lesions at the final visit with respect to baseline as assessed by the investigator.

    8 weeks after the last PDT

  • Treatment success defined by a minimum improvement of the modified investigator global assessment (mIGA) score by at least 2 assessed 8 weeks after the last PDT and resulting in an mIGA score of 0 (clear) or 1 (almost clear).

    Treatment success is defined as a minimum improvement of the mIGA score by at least 2 and resulting in an mIGA score of 0 (clear) or 1 (almost clear).

    8 weeks after the last PDT

Secondary Outcomes (11)

  • Absolute and/or percentage change from baseline in the number of lesions as assessed by investigator.

    4 or 8 weeks after the last PDT

    4 or 8 weeks after the last PDT

  • Absolute and percentage change from baseline in the number of lesions as assessed by investigator, only for responders at Visit 3 / 4 weeks after PDT-1.

    4 or 8 weeks after PDT-1

  • Absolute and percentage change from baseline in the number of lesions as assessed by investigator, only for responders at Visit 4b / 4 weeks after PDT-2.

    4 or 8 weeks after PDT-2

Combination Product: 3h Incubation Photodynamic therapy (PDT) (ALA-PDT, Ameluz®-PDT)

1h incubation vehicle

PLACEBO COMPARATOR

Topical application of vehicle to BF-200 ALA red light photodynamic therapy (PDT) utilizing BF-RhodoLED® after 1h incubation.

Combination Product: 1h Incubation Photodynamic therapy (PDT) (vehicle to BF-200 ALA containing no active ingredient)

3h incubation vehicle

PLACEBO COMPARATOR

Topical application of vehicle to BF-200 ALA red light photodynamic therapy (PDT) utilizing BF-RhodoLED® after 3h incubation.

Combination Product: 3h Incubation Photodynamic therapy (PDT) (vehicle to BF-200 ALA containing no active ingredient)

Interventions

The treatment field (whole face excluding the periocular area) will be cleansed with gauze soaked with ethanol or isopropanol. Afterwards, approximately 1 tube of study medication will be applied as a thin layer. After drug application, subjects should stay inside for 1 hour. Post incubation, red light illumination with BF-RhodoLED® will be performed according to the lamps user manual until a total light energy of 37 J/cm2 was applied. To cover the whole face 2 illuminations will be required which can either be performed subsequentially or in parallel (with 2 lamps). Other Names: ALA-PDT, Ameluz®-PDT

The parent(s) or legal guardian(s) must also provide informed consent/HIPAA for the subject.
  • Subjects with moderate to severe acne on the face (IGA ≥3).
  • Presence of ≥20 inflammatory and ≥20 non-inflammatory (open and closed comedones) Acne vulgaris lesions on the face (should be located within not more than 2 illumination areas) as assessed by investigator.

(Reassessment of subjects is allowed once if the sunburn or other confounding skin conditions is/are expected to resolve within the screening period.
  • Reassessment can be done on the day of the actual treatment.)
