Trial Summary

What is the purpose of this trial?

The goal of this clinical trial is to see if shorter Photodynamic Therapy (PDT) treatment times will still be effective at treating actinic keratoses (AK) while reducing or eliminating the pain that patients sometimes experience during conventional PDT treatment. The main questions it aims to answer are: * Will the application of the nanoemulsion (10% ALA gel), in the absence of occlusion, still achieve significant inflammation and lesion clearance? * Will shortened incubation times of Ameluz still achieve significant inflammation and lesion clearance? * Will the new test regimens achieve reduced pain during illumination? * Will the new test regimens be safe? Participants will be randomly assigned to one of three treatment regimens, which will determine the length of time that the topical medication will incubate on the face before red light exposure in PDT treatments. The incubation period will be either 10 minutes, 20 minutes, or 60 minutes.

Eligibility Criteria

This trial is for individuals with at least 10 actinic keratoses lesions on their face, who are not pregnant or nursing, and have stopped any topical AK treatments for a month. It excludes those undergoing cancer treatment, allergic to the study materials, or with photosensitivity diseases.

Inclusion Criteria

I have at least 10 rough, scaly patches on my face.

I will not become pregnant during the study.

Subjects must be able to understand and willing to sign a written informed consent document.

Exclusion Criteria

I stopped using topical treatments on my AKs at least a month ago.

I am not receiving treatment for another cancer.

Pregnant or nursing.

Participant Groups

The trial tests if shorter contact times using a nanoemulsion (10% ALA gel) before red light exposure in PDT can effectively treat actinic keratosis with less pain. Participants will be randomly assigned to one of three groups based on different incubation times: 10, 20, or 60 minutes.

Group I: Regimen C Experimental Treatment 2 Interventions

Apply topical aminolevulinic acid gel and incubate for 60 minutes prior to red light source

Group II: Regimen B Experimental Treatment 2 Interventions

Apply topical aminolevulinic acid gel and incubate for 20 minutes prior to red light source

Group III: Regimen A Experimental Treatment 2 Interventions

Apply topical aminolevulinic acid gel and incubate for 10 minutes prior to red light source
