NCT05171894
This is a multi-center, randomized, double-blind, vehicle-controlled, and sequential group Phase 2 study. Eligible subjects aged 18 to 75 years old with PWB will receive Hemoporfin PDT or vehicle PDT in 8-week cycles at fixed drug dose (5 mg/kg) and different light fluence.
NCT04336163
The purpose of this study is to obtain information (such as lesion depth, depth of the most superficial part of the lesion, and the size and density of blood vessels) with the assistance of an imaging device, and use this information to assist in selection of laser settings for the treatment of skin conditions. The imaging modality is called Optical Coherence Tomography (OCT). Multiple laser modalities will be used, including intense pulsed light lasers (BroadBand Light, Profractional Sciton), pulsed dye lasers (Vbeam Perfecta, Candela), long-pulse 755nm lasers (GentleLASE, Candela), Sciton long-pulse 1064nm lasers, and non-ablative and ablative fractional resurfacing lasers (Profractional, Sciton). All of the lasers noted above are the only ones that will be used in this study. These lasers have 510k clearance and are being used as per their approved indications in this study. The choice of laser type is based on the skin lesion and is recommended by the physician, and the subjects who are going to enroll in this study will already be planned to undergo laser treatment as a standard of care for their condition. This is a pilot study that will explore the utility of skin imaging in guiding the laser treatment of skin lesions.
NCT03181984
This study is to provide safety information of hemoporfin during the post-marketing period as required by China Food and Drug Administration (CFDA) regulations in order to identify any potential drug related treatment factors in the Chinese population, such as unknown/unexpected adverse reactions, the incidence of adverse reactions under the routine drug uses.
NCT05771311
To compare the efficacy and safety of 532nm KTP laser and 585 nm pulsed dye laser for treating port-wine stains.
NCT01774552
Port-wine stain is a congenital, progressive vascular malformation of human skin involving post-capillary venules that occurs in an estimated 0.3% of children and can alter personality development and psychological in children.
NCT01924273
Port wine stains Birthmark are congenital, progressive vascular malformations of the skin that occur in approximately 0.7% of newborns. Approximately 1.5 million individuals in the United States and 32 million people worldwide have Port wine stains birthmarks. Two-thirds of these malformations occur on the face. Personality development of virtually all patients is adversely affected as a result of the negative reaction of others to a "marked" person. Detailed studies have documented lower self-esteem and difficulties with interpersonal interactions in Port wine stains patients. Port wine stains are initially flat and red, but with time, they tend to darken to purple and become thickened as vascular nodules develop. This thickening occurs in approximately two-thirds of lesions and further disfigures the facial features of many patients.
NCT02051101
The purpose of this study is to investigate the pathogenic mechanisms of Port Wine Stain, collect biopsy samples and blood samples to characterize exosomes and metabolites from Port Wine Stain.
NCT00540917
Lasers are the treatment modality of choice for Port Wine Stain birthmarks.The epidermis is not totally spared due to partial absorption of energy therein by melanin that presents an optical barrier through which the light must pass to reach the underlying blood vessels. Absorption of laser energy by melanin causes localized heating in the epidermis, which may, if not controlled, produce permanent complications such as hypertrophic scarring or dyspigmentation.
NCT00667472
The purpose of this study is to improve port wine stain therapeutic outcome in response to laser therapy. The researcher want to determine whether the combined use of pulsed dye laser therapy and topical ranibizumab will improve port wine stain therapeutic outcome.
NCT03125057
This pilot study aims to evaluate the efficacy and safety of hemoporfin photodynamic therapy (PDT) with different light doses for port-wine stain (PWS） in 7-14 years old children. The population pharmacokinetics of hemoporfin in children will be investigated as well.
