This study is testing a reformulated version of Levulan Kerastick (aminolevulinic acid HCl 20%) combined with blue light Photodynamic Therapy (PDT) for treating actinic keratosis (AK) on the face or bald scalp. Researchers want to see how well this treatment works compared to a vehicle (a solution without the active ingredient). You may be eligible if you are an adult between 18 and 85 years old and have 4-8 mild to moderate AK lesions on your face or bald scalp. The main goal is to see how many patients achieve complete clearance of their AK lesions by Week 12. The current status of this study is unclear.

Study design

This is a Phase 3, randomized, multi-center study involving about 160 adult patients. It is evaluator-blind, meaning the people assessing your progress won't know which treatment you received, and it compares the active drug to a vehicle.

What's involved

You would be randomized into one of four treatment groups. You may receive up to two PDT sessions, depending on how your lesions clear.

Compensation

Not stated in the trial record.

Follow-up

Your progress will be measured at Week 12 to see if your lesions have completely cleared.
