Photodynamic Therapy (PDT) With Levulan and Blue Light for the Treatment of Actinic Cheilitis

The study will consist of a screening visit, up to three scheduled treatments, and two scheduled office visits. There can be a three-day window period for each scheduled visit in order to accommodate the subject's schedule and unforeseen scheduling conflicts.

1. Visit 1 (Screening): Subjects can be screened for the study up to two weeks before Visit 2 (Baseline). During screening, the study will be reviewed, written informed consent obtained, and eligibility confirmed. If applicable, the washout from prohibited medications or treatments will be determined at this visit.
2. Visit 2 (Baseline): Following signed, written informed consent and confirmation of eligibility, all subjects will have their lips photographed. Medical history, dermatologic exam, urine pregnancy test (if applicable), review of concomitant medications, clinical evaluations, and tolerability assessments will be performed at this visit. Study medication application to clean skin will be followed by a 90 minute incubation period under occlusion. Subsequently, patients will be exposed to blue light therapy for 16 minutes and 40 seconds. Post-therapy assessments will be performed afterwards, as well as education on appropriate sun protection methods.
3. Visits 3-4: Subjects will return every six weeks for up to two additional treatments. Treatment will be discontinued once the patient has achieved clinical clearance. Tolerability assessments, study medication application, blue light therapy, post-therapy assessments, and photographs will be performed.
4. Visit 5-6 (End of Study): Subjects will return 12 and 24 weeks after the last treatment for clinical evaluations, tolerability assessments, and photographs.
