Fractional CO2 Laser Assisted Photodynamic Therapy
Conventional Versus Fractional CO2 Laser Assisted Photodynamic Therapy for Basal Call Carcinomas and Actinic Keratoses

Nodular Basal Cell Carcinomas:

Compare the efficacy and safety of conventional versus fractional laser assisted PDT for difficult to treat nodular cell carcinomas in the face.

Actinic keratosis:

Compare the efficacy and safety of conventional versus fractional laser assisted PDT for moderate to severe actinic keratoses located in the face and on the hands.

Phase 2
Phase 3
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Single Blind (Outcomes Assessor)
Primary Purpose: Treatment
  • Actinic Keratosis
  • Basal Cell Carcinoma
  • Drug: Conventional photodynamic therapy
    Photodynamic therapy using methyl-aminolevulinate and red light (37 J/cm2)
  • Drug: Fractional CO2 laser assisted PDT
    Pretreatment with fractional CO2 laser before methyl-aminolevulinate PDT
  • Active Comparator: AK split-face treatment
    Split-face treatment of two symmetrical areas with moderate to severe actinic keratoses. One area is treated with conventional PDT the other with fractional laser assisted PDT.
    Interventions:
    • Drug: Conventional photodynamic therapy
    • Drug: Fractional CO2 laser assisted PDT
  • Active Comparator: Fractional laser assisted PDT for BCC
    Difficult to treat nodular basal cell carcinomas in the face is pretreated with fractional CO2 laser followed by methyl-aminolevulinate PDT.
    Intervention: Drug: Fractional CO2 laser assisted PDT
  • Active Comparator: Konventional PDT for BCC
    Difficult to treat nodular basal cell carcinomas in the face is treated with methyl-aminolevulinate PDT.
    Intervention: Drug: Conventional photodynamic therapy
