The purpose of this study is to determine whether erlotinib is effective in the treatment of psoriasis.
研究概览
详细说明
Psoriasis vulgaris is a disease that affects 25 million people in North America and Europe.
It often presents in late adolescence and usually persists for life.
Current therapies target specific immune molecules that are implicated in the cause of this disease.
For example, biologic agents that are used in severe psoriasis are aimed at inflammatory mediators.
These therapies have been proven to be effective but also have their limitations.
