Excimer Light for Alopecia Areata

Status Recruiting

Clinical Trial Summary

Alopecia Areata (AA) is a chronic autoimmune inflammatory disease causing nonscarring hair loss. Many treatment modalities have been found to be helpful in AA, however, none on them cure the disease. UVB excimer light has recently emerged as a new therapeutic modality in many dermatologic diseases. There are no prospective randomized controlled trials evaluating the efficacy and safety of UVB excimer light in AA. We plan on conducting a prospective split lesion single-blinded randomized clinical trial to assess efficacy and safety of UVB excimer light in the treatment of AA.

Clinical Trial Description

Alopecia Areata (AA) is a chronic autoimmune inflammatory disease causing nonscarring hair loss. Many treatment modalities have been found to be helpful in AA, however, none on them cure the disease.

Excimer laser has been shown to be effective in the treatment of AA in controlled studies. The main disadvantage of the previous studies evaluating excimer laser is choosing separate patches as a control which does not account for interlesional treatment response variability. UVB excimer light has recently emerged as a new therapeutic modality in many dermatologic diseases. However, there are only a few studies that evaluated the efficacy and safety of UVB excimer light in AA. Those studies have shown that UVB excimer light is effective in the treatment of AA but none of them was conducted in a controlled fashion.

There are no prospective randomized controlled trials evaluating the efficacy and safety of UVB excimer light in AA. We plan on conducting a prospective split lesion single-blinded randomized clinical trial to assess efficacy and safety of UVB excimer light in the treatment of AA.

Study Objectives

1. To evaluate the potential for UVB excimer light to induce hair regrowth within AA patches.

2. To assess the side effect profile of UVB excimer light when used in the treatment of AA. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
