Interventions

NameTypeDescription
1h Incubation Photodynamic therapy (PDT) (ALA-PDT, Ameluz®-PDT)COMBINATION_PRODUCTThe 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

Frequently asked questions about 1h Incubation Photodynamic therapy

What is 1h Incubation Photodynamic therapy used for?

1h Incubation Photodynamic therapy is being studied for the treatment of moderate to severe acne vulgaris in adults. It combines a photosensitizing agent with light activation to treat inflammatory acne lesions. The approach is being developed by Biofrontera Inc. as a dermatology treatment option for patients with acne.

Who is developing 1h Incubation Photodynamic therapy?

1h Incubation Photodynamic therapy is being developed by Biofrontera Inc., which trades under the ticker BFRI. The company is evaluating the therapy in dermatology, specifically for moderate to severe acne vulgaris. Biofrontera Inc. is the sponsor of the clinical program for this photodynamic therapy approach.

What phase is 1h Incubation Photodynamic therapy in?

1h Incubation Photodynamic therapy is in Phase 2 clinical development. The completed Phase 2 trial enrolled 120 participants with moderate to severe acne vulgaris. The therapy is investigational and has not been approved for the treatment of acne vulgaris.

What clinical trial has studied 1h Incubation Photodynamic therapy?

The Phase 2 trial NCT05080764 evaluated the safety and efficacy of BF-200 ALA (Ameluz) and BF-RhodoLED in the treatment of moderate to severe acne vulgaris with photodynamic therapy in adults. The trial was completed, enrolled 120 participants, and was conducted in the United States.

Is 1h Incubation Photodynamic therapy the same as ALA-PDT or Ameluz-PDT?

Yes. 1h Incubation Photodynamic therapy is also known as ALA-PDT and Ameluz-PDT. These names refer to the same photodynamic therapy approach that uses a photosensitizing agent activated by light. The therapy is being developed by Biofrontera Inc. for moderate to severe acne vulgaris.

How was the Phase 2 trial of 1h Incubation Photodynamic therapy designed?

The Phase 2 trial NCT05080764 was a randomized, double-blind, placebo-controlled study of 1h Incubation Photodynamic therapy in moderate to severe acne vulgaris. It enrolled 120 participants aged 16 years and older in the United States. The trial has been completed.
