Use of Etanercept in the Treatment of Moderate to Severe Lichen Planus
Trial ID: NCT00285779
The purpose is to assess the response of subjects to etanercept (as compared to placebo) in treating the physical signs of mucosal and cutaneous lichen planus. The investigators also wish to assess the effect of etanercept on disease-related itching, pain, and serious adverse events in patients with lichen planus.
