Evaluating Photodynamic Therapy Used to Treat Cutaneous Squamous Cell Carcinoma in Situ (isSCC) on the Face, Upper Extremities & Trunk.

An Investigator Initiated Study to Evaluate the Safety and Efficacy of Aminolevulinic Acid 20% Topical Solution (Levulan® Kerastick®) (ALA) With Blue Light Model 4170E in the Treatment of Cutaneous Squamous Cell Carcinoma in Situ (isSCC) Located on the Face, Upper Extremities and Trunk.

The goal of this clinical trial is to test how safe and effective it is to treat early form of cancer cells found in the upper skin layer of the face, upper extremities and trunk, using a light sensitive cream used in combination with a light source.

The main questions this trial aims to answer are:

  • to confirm using laboratory testing, how much of the affected skin cancer section the treatment was able to remove, and;
  • seeing how many participants had no remaining affected skin cancer sections after treatment.

Participants who qualify will be asked to complete 12 visits in total and will receive a total of two treatments, after voluntarily consent has been given.

Detailed Description

In the study, participants will be asked to complete the following:

  • Provide basic personal information (including date of birth, gender, race and ethnicity)
  • Provide their medical/ surgical history and perform a medical exam (including but not limited to physical exam, skin type, vital signs, height, weight and urine pregnancy test collection)
  • Follow study rules such as avoiding certain medications and treatments
  • Allow photographs of the area of skin cancer being treated on the face or upper extremities/ trunk.
  • Provide information on any medications, treatments or reactions that started after the study began
  • Allow two treatments on the skin cancer area of the face upper extremities/ trunk using a light sensitive cream used in combination with a light source
  • Allow clinical documentation of the treatment, such as how well the treatment was tolerated, any skin reaction or side effects
  • Allow surgery to remove the skin cancer area from the face or upper extremities/ trunk for Laboratory testing

To qualify for this trial, participants must:

  • be an adult (18 years of age or older)
  • give voluntary written consent
  • have a recently diagnosed (less than six months from first visit) skin cancer area on the face or upper extremities/ trunk that meets surgery size requirements
  • be willing to follow study instructions and complete study requirements, including not using non-approved lotions and creams on the treatments areas
  • (if female) not be pregnant before and during the study and agree to use acceptable forms of birth control
  • confirm they are not sensitive to any of the study treatment ingredients

All surgery samples collected from the participants towards the end of the study will be sent to a laboratory for testing.

All photographs of the treatment area collected during the study will be used as study data.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Facial isSCC Photodynamic Therapy (Blue light dose 20 J/cm2)

8 participants will be enrolled to this arm.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
