Population Pharmacokinetics and Exposure-Response Relationship of Hemoporfin in Pediatric Patients With Port-Wine Stain.

ABSTRACT: Hemoporfin, a porphyrin derivative photosensitizer, has been approved for the treatment of port-wine stain (PWS) in adults. However, its optimal dose for the pediatric population remains unclear. This study aimed to explore appropriate dosing for pediatric patients with PWS through population pharmacokinetics (PopPK) and exposure-response (ER) analysis. Data from a prospective pilot study of hemoporfin photodynamic therapy in pediatric PWS patients, as well as a phase I study in healthy adult volunteers, were utilized for the analysis. The pharmacokinetics of hemoporfin in the pediatric population can be described by a three-compartment model with linear elimination following allometric scaling rules. Simulations indicated that simply scaling down the approved adult dose of 5 mg/kg based o
