Clinical Trial Summary
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.
Description:
Pulsed dye laser is currently the standard of care treatment for Port wine stains.
Researchers at University of California Irvine at Beckman Laser Institute Medical Clinic can
use Photodynamic therapy, another treatment option for Port wine stains. Photodynamic therapy
involves light activation of a photosensitizer (a drug that is responsive to light or radiant
energy). Because the photosensitizer can be localized to a desired portion of the Port wine
stain, Photodynamic therapy creates an opportunity for targeted destruction of Port wine
stains.
Researchers will use a photosensitizer medication called Talaporfin sodium, an intravenously
administered investigational photosensitizer, being evaluated for multiple clinical
indications. Photodynamic therapy with talaporfin sodium has been investigated for many
different conditions, and can be used for treatment for Port wine stains. Photosensitivity
precaution instructions will be provided, including appropriate photo protective clothing,
protective hat and sunglasses that wrap around the temples to help minimize lateral sun light
exposure when traveling home following discharge from the study site.
For efficacy, evaluated study variable will be Port wine stain blanching, and the researchers
can use diffuse reflectance imaging chromametry, Laser Speckle Imaging and Spatial Frequency
Domain Imaging to measure the change of Port wine stain blanching. The maximum power of the
Laser Speckle Imaging and Spatial Frequency Domain Imaging light source is 10-50 mW, which is
comparable to halogen-bulb household flashlights. Efficacy will be evaluated based on
comparison of pre-treatment visit and post treatment day 1, week 1, week 4, and week 12
measurements.
