Combined Photodynamic and Pulsed Dye Laser Treatment of Port Wine Stains (PDT/PDL)

This research study was designed to determine the effect on port wine stains (PWS) of liposomal benzoporphyrin derivative monoacid (BPD-MA) termed verteporfin by intravenous (IV) infusion for photodynamic therapy (PDT) or combined PDT and pulsed dye laser (PDL) therapy (PDT + PDL). The standard treatment for PWS is PDL alone. This lightens some PWS but many lesions are not completely removed.

PDT uses a medication and light together to cause injury to a target. The medication is given and then light is directed at the desired area of treatment to achieve an effect. PDT has been used to treat some skin conditions including pre-cancers and skin cancers. Using PDT or PDT immediately followed by PDL therapy may improve PWS lightening. At this time, both PDT and PDT + PDL therapy for treatment of PWS is investigational. The type and amount of medication and light which may be used to treat PWS is not known, and is likely to be different than those used for other PDT treatments.

Study Overview

• Status: Completed
• Conditions: Port Wine Stains
• Intervention / Treatment: Drug: Combined Photodynamic & Pulsed Dye Laser Treatment

Detailed Description

Procedures will be performed at the Surgery Laser Clinic at the Beckman Laser Institute at the University of California, Irvine.

At an initial visit, a brief history and physical will be performed.

The history will include: 1) previous treatment to my PWS; 2) current medications; 3) history of light sensitivity; 4) risk of pregnancy and use of birth control in a female of child-bearing age.

The physical will include: 1) measurement and evaluation of PWS; 2) measurement of blood pressure, blood cell count, general chemistries (including liver function tests) and ANA, which might indicate an increased sensitivity to light.

On the day of treatment, the same brief physical and history will be repeated. A urine pregnancy test will be performed on females of child-bearing age.

Four circular test sites of PWS will be selected. One test site will receive no treatment. The second test sites will be treated with the pulsed dye laser at standard setting and protective eyeglasses to shield the eyes during the laser treatment.

For two additional test spots, the photodynamic therapy (PDT) verteporfin will be administered intravenously over a 10-minute period. After receiving the verteporfin, the skin and eyes will be sensitive to light for the next 5 days. The light sensitive protection precautions will be instructed.

Optical Doppler Tomography unit (ODT) measurements, similar to shining a flash light to PWS and measuring the light response, which provide information about how blood is flowing through the PWS.

Photographs and light measurements will be taken during follow-up visits on day 1, day 3, and 1, 2, 4, 8 and 12 weeks after the study treatment. At these visits blood may also be drawn to check for blood substances that promote blood vessel formation.

At the end of the study, blood tests will be drawn to assess cell count and general chemistries.
