BACKGROUND AND OBJECTIVES: Photodynamic therapy (PDT) has shown potentially beneficial results in treating port-wine stain, but its benefit-risk profile remains undefined. This study aimed to evaluate the efficacy and safety of PDT conducted with hemoporfin and a 532 nm continuous wave laser to treat port-wine stain clinically. PATIENTS AND METHODS: This randomized clinical trial was conducted in eight hospitals in China. Participants were adolescent and adult patients (age range: 14-65 years old) with port-wine stain...

BACKGROUND: Vascular-acting photodynamic therapy (PDT) might be an alternative approach for treating port wine stain (PWS) birthmarks, but the usefulness of PDT for pediatric patients has not been fully investigated. STUDY DESIGN: Medical records of pediatric patients (3-10 years old) with red and purple facial PWS were analyzed. Clinical outcomes after one session of PDL (585 nm, 4.8-6.5 J/cm(2)) and PDT (Hemoporfin - 3.5mg/kg, copper vapour laser - 120 J/cm(2)) were compared...

BACKGROUND: Several Chinese studies suggest that Hemoporfin-mediated photodynamic therapy (PDT) is an alternative treatment for port-wine stain (PWS) birthmarks. OBJECTIVE: To evaluate treatment responses and adverse effects associated with Hemoporfin PDT for the treatment of PWS and their management. METHOD: The medical records of 700 patients who underwent PDT treatment in our center were retrospectively examined. Treatment-related reactions and adverse effects were reviewed...

We report on some of the optical properties of Hemoporfin (hematoporphyrin monomethyl ether, HMME), a photodynamic therapy (PDT) photosensitizer that has been in clinical trials in China since the early 1990s. We characterized the photosensitizer on the basis of one- and two-photon absorption and fluorescence emission. The effects of photobleaching were probed to characterize its decay kinetics. Additionally, we determined time resolved fluorescence and thermal effects on fluorescence and absorption properties...

REVIEW
Yu Pu, Wenhui Chen, Zhengwei Yu
The second generation photosensitizer Hemoporfin (7(12)-(1-methoxyethyl) -12(7)-(1-hydroxyethyl)-3,8,13,17-tetramethyl-21H,23H-porphin-2,18-dipropionic acid) is a porphyrin derivative which processes a stable structure, high singlet oxygen yield, high photoactivity, low dark toxicity and fast clearance rate. Hemoporfin, also known as hematoporphyrin monomethyl ether (HMME) has been studied and used in photodynamic therapy (PDT) in China since 1989. This series of reports will provide an overview on the preclinical and clinical studies of this PDT photosensitizer...

AIM: To investigate the safety, tolerability and pharmacokinetics of intravenous hemoporfin, a novel photosensitive drug for the treatment of port-wine stain (PWS), in healthy Chinese volunteers following single-dose administration. METHODS: Thirty-six healthy Chinese subjects were enrolled. The subjects were administered hemoporfin (2.5, 5, 7.5 or 10 mg/kg) via single-dose intravenous infusion. Pharmacokinetics of the drug were studied in the groups with doses of 2...

BACKGROUND/PURPOSE: This phase IIa study aimed to study the efficacy and safety of hemoporfin in photodynamic therapy (PDT) with a 532 nm continuous laser for port-wine stain (PWS). METHODS: In this 8-week open-labeled study in three centers, three different laser exposure times (532 nm continuous laser for 20, 30 and 40 min) were used in stage I, group A, stage II, group B and stage III, group C, respectively. Primary efficacy assessment was performed by an independent group of experts, who reviewed the standardized photos...

Hemoporfin is a novel second-generation porphyrin-related photosensitizer for ovarian cancer photodynamic treatment (PDT). The purpose of this study was to investigate the molecular mechanisms of Hemoporfin-mediated photocytotoxicity. Human epithelial ovarian cancer cell line 3AO was incubated with different concentrations of Hemoporfin, and phototoxic effects of Hemoporfin on cells were determined using a Cell Viability Analyzer. Apoptosis or necrosis was determined by flow cytometry analysis using the Annexin V-FITC apoptosis kit...

Hematoporphyrin monomethyl ether (Hemoporfin) is a novel porphyrin-related photosensitizer. Photocytotoxic effect of Hemoporfin to ovarian cancer is still unclear. We used human epithelial ovarian carcinoma cell line SKOV3 and its xenograft model in nude mice to investigate the Hemoporfin-based photodynamic therapy (PDT) for ovarian cancer. The growth rates of SKOV3 cells were determined by MTT assays. Flow cytometry combined with dual Annexin V/PI staining was used to identify the death mode of the cells following PDT...
