Clinical Outcomes in Patients With Psoriasis Following Discontinuation of Efalizumab Due to Suspension of Marketing Authorization

In February 2009, the European Medicines Agency suspended the marketing authorization for efalizumab after 3 confirmed cases of progressive multifocal leukoencephalopathy were reported. To assess the consequences of this decision, we performed a prospective follow-up study of patients in our department who were being treated with efalizumab at the time and compared clinical outcomes with data from the literature.
