FDA: PML is Fatal, No Cure or Treatment

Progressive Multifocal Leukoencephalopathy (PML) is a rare, often fatal viral disease of the central nervous system that affects patients with immunosuppressive conditions and those treated with immunomodulatory agents.

No products are approved for the treatment of PML and no therapeutic development pathway is established for PML

Who is most at risk for PML?

Most PML cases today are linked to medications used to treat Multiple Sclerosis (MS) and a variety of cancers.

PML can result from immune suppression caused by HIV/AIDS, leukemias, and other immunocompromising conditions.

A comprehensive list of PML-causing agents can be found in the section below.
