Drug-induced progressive multifocal leukoencephalopathy in multiple sclerosis: European regulators' perspective

Clin Pharmacol Ther. 2017 Aug;102(2):283-289. doi: 10.1002/cpt.604. Epub 2017 Jan 23.

Abstract

Progressive multifocal leukoencephalopathy (PML) has been associated with the use of a number of multiple sclerosis (MS) immunomodulatory therapies and has assumed a critical place in the evaluation of their benefit/risk. In this review, we discuss the European Union regulatory approach to drug-induced PML in MS, highlight a number of key issues related to the current knowledge on PML, and outline possible paths to help progress the risk management of patients with MS at risk of PML.
