Treatment of Cutaneous Lupus Erythematosus (CLE) With the 595 nm Flashlamp Pulsed Dye Laser

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT00523588

Brief Summary:
The purpose of using the 595 nm Vbeam Perfecta™ flashlamp-excited, pulsed dye laser in this study is to help improve study patients' skin disease. Cutaneous lupus erythematosus (CLE) often presents with disfiguring vascular lesions which are frequently difficult to treat with the available therapeutic measures, such as photoprotection, topical steroids, and antimalarials. Laser therapy provides an alternative treatment option for CLE patients. Although there has been documented experience with laser treatment in CLE patients, no study comparing treated lesions to the natural course of the disease has been conducted.

Condition or disease Intervention/treatment Phase
Cutaneous Lupus Erythematosus Procedure: laser treatment (Candela Vbeam Perfecta™) Phase 2

Detailed Description:

The Candela Vbeam PerfectaTM is an FDA approved 595nm Flashlamp Pulsed Dye Laser (PDL) that is being used for the treatment of benign skin lesions. The purpose of using the PDL in this study is to help improve study patients' skin disease. Cutaneous Lupus Erythematosus often starts with damaging skin lesions which are frequently difficult to treat with the available therapeutic measures. This study will use a flashlamp PDL to compare treated cutaneous lesions and non-treated lesions. We will look at factors such as the degree of erythema (redness of the skin), scale and hypertrophy (increase in size of skin), scarring and dyspigmentation (abnormality in the formation or distribution of skin coloration) and make a summary score of these factors.

It is important to note that this device currently is being used to treat patients with skin lesions in the Department of Dermatology at the University of Pennsylvania, where this study will be done. Although the PDL has been used to treat other patients, its use in this study is experimental.

The PDL is considered to be the laser of choice for vascular lesions, because at wavelengths of 585-595 nm, the laser is known to produce excellent clinical results at minimal risk to patients. The laser has been used successfully in the treatment of port-wine stains in children as young as 1 month of age. The PDL is designed to deliver an intense but gentle burst of laser light to the skin. The light is absorbed by the blood vessels in the vascular lesion, while leaving the surrounding tissue undamaged. The PDL has been used clinically for the treatment of cutaneous lesions in childhood port-wine stains, childhood proliferative angiomas, facial telangiectasias, poikiloderma of Civatte, nevus flammeus, capillary hemangiomas, scars, verrucae, and lupus erythematosus. Several studies are known to have used the 585-595nm PDL to treat cutaneous lupus erythematosus lesions.

During a period of 5 months, study patients will receive 3-5 treatments to one skin lesion with the pulsed dye laser. Clinical follow-up examinations include photographs, clinical assessments by a blinded physician, and pain and itch scales by the study patient. The study requires a total of one year commitment per study patient.

Intervention Details:
  • Procedure: laser treatment (Candela Vbeam Perfecta™)
    This laser has an adjustable pulse duration (0.45-40 ms), fixed wavelength 595 nm, spot size (3 mm, 5 mm, 7 mm, and 10 mm), and incident fluence range of 10-40 J/cm2. The laser is also equipped with a dynamic cooling device (DCD) (FDA cleared under K001589) that delivers cryogen (R-134a) from a small nozzle positioned 4 cm above the skin at an angle of approximately 70 degrees with respect to the skin surface. All patients will be treated with the laser device on which the varying cooling device parameters will be selected based on the clinical judgment of the treating physician. Factors used in this decision include patient age, skin type and epidermal pigmentation, size and depth of vessels, color of lesions, anatomic location, etc. In all instances, a test-dose in an inconspicuous location on the skin will be conducted prior to the first treatment.

Primary Outcome Measures :
  1. Comparison of laser treated CLE skin lesions with a non-treated control CLE lesion of the same patient evaluated by the CLASI (Cutaneous Lupus Erythematosus Disease Area and Severity Index) and the M-CLASI (Modified CLASI). [ Time Frame: One year ]

Secondary Outcome Measures :
  1. Pain and itch relief compared to baseline and between the treated and untreated lesion [ Time Frame: One Year ]
  2. Reduction or increase in CLASI and MCLASI scores compared to baseline, and adverse events [ Time Frame: One year ]
