Chronic Plaque Psoriasis (Ps) Registry

ESPRIT is a 10 year registry of patients taking HUMIRA® for Psoriasis. Patients who volunteer to participate will be asked to provide information about their medical history and experiences with HUMIRA®. No registry specific testing will be performed. Patients will be asked to provide data on their experiences with HUMIRA® approximately every 6 months, or as determined by the study doctor. No drug will be provided as a result of participation in the registry. All treatment decisions are independent of participation in the registry.
