The Immunological Basis for Treatment Resistance to Anti-TNF Treatments

Completed · Phase 4

Conditions studied: Psoriasis

In brief

The purpose of this study is to determine the relationship between two types of cell signals, type I interferon (IFN) and tumor necrosis factor (TNF), in psoriatic skin prior to and during treatment with etanercept and correlate that information with the degree of the improvement in the psoriasis.
