What this Trial Is About
This research aims to evaluate the safety and effectiveness of different light doses in treating adults aged 18 to 75 with Port-Wine Birthmarks (PWB). The study is a multi-center, randomized, double-blind, vehicle-controlled Phase 2 trial conducted in two sequential stages. It focuses on comparing Hemoporfin photodynamic therapy (PDT) with a vehicle (placebo) control using fixed drug dosing and varying light fluences. Participants will be randomly assigned to receive either Hemoporfin PDT or vehicle PDT via intravenous infusion at a fixed dose of 5 mg/kg. They will undergo fixed laser irradiation for a set time in cycles lasting 8 weeks. Each participant may receive up to three treatment cycles. The study consists of a Screening Period, Treatment Period, efficacy evaluation for subsequent treatment, and an End of Study phase, lasting up to approximately 44 weeks. Throughout the study, participants will be closely monitored for local and systemic adverse events. Researchers will assess changes in PWB severity using the Port Wine Birthmark-Investigator Global Assessment (PWB-IGA) scale and other measures from baseline until the study’s end. Regular evaluations include physical exams, safety assessments, and efficacy reviews, ensuring participant health and adherence over the entire study duration.
