Study of Reformulated Levulan Kerastick Plus PDT for Actinic Keratosis on Upper Extremities

Recruiting now · Phase 3

Conditions studied: Actinic Keratosis

In brief

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 upper extremities. Approximately 260 adult patients with 4-8 mild to moderate AK lesions on one arm will be randomized to receive either active treatment or vehicle control, followed by exposure to blue light. 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.
