SUPPLEMENTARY INFORMATION:

I. Background

    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. FDA 
seeks to discuss scientific and regulatory challenges associated with 
designing clinical trials evaluating PML treatments, and to develop PML 
clinical trial designs that are feasible, adequate to establish 
substantial evidence of effectiveness, adequate to characterize the 
safety profile of investigational treatments, and acceptable to PML 
patients, clinicians, regulators, and industry.
    The Agency encourages healthcare providers, employees of other U.S. 
Government agencies, academic experts, industry experts, patients and 
patient advocates, and other stakeholders to attend this public 
workshop.

II. Topics for Discussion at the Public Workshop

    Discussions are planned around the following topics areas:
     Unmet need for PML therapeutics.
     Key trial design considerations, including feasibility, 
trial populations, selection of control groups, endpoints, adaptive 
designs, and master protocols.
