Study of Reformulated Levulan Kerastick Plus PDT for Actinic Keratosis on Face and Scalp
brief summary
This Phase 3, randomized, multi-center, evaluator-blind, vehicle-controlled study evaluates the efficacy and safety of reformulated Levulan Kerastick (aminolevulinic acid HCl 20%) combined with photodynamic therapy (PDT) for field-directed treatment of actinic keratosis (AK) on the face or bald scalp. Approximately 160 adult patients with 4-8 mild to moderate AK lesions will be randomized into four treatment arms based on two variables: type of treatment (active drug or vehicle) and incubation time. During the study, up to 2 PDT sessions may be administered depending on the clearance of lesions. The primary endpoint is complete clearance rate (CCR) at Week 12. Secondary endpoints include AK clearance rate (AKCR), partial clearance, change in total lesion count and area, recurrence rate, cosmetic response, and patient satisfaction. Safety assessments include adverse events, local skin reactions, vital signs, and lab tests.
