MAIN STUDY: Switching Relapsing Multiple Sclerosis Patients Treated With Natalizumab at Risk for Progressive Multifocal Leukoencephalopathy to Teriflunomide: Is This Safe and Effective? SUB-STUDY: Analysis of JCV Antibody Index in MS Patients Treated With Teriflunomide
In Brief
A Phase 4 clinical trial evaluating teriflunomide for Multiple Sclerosis. Completed, enrolled 55 participants across 3 sites.
Detailed Summary
MAIN STUDY: The purpose of this study is to determine if teriflunomide will be safe and effective to prevent relapses in patients with relapsing types of MS when switching from natalizumab to teriflunomide in patients at risk for PML. This is a two center interventional study of patients who have had 12 or more continuous infusions of natalizumab , who are anti-JCV-ab positive, and who had been free of clinical relapses during prior 12 months of natalizumab therapy who will be switching to teriflunomide. SUB-STUDY: To study the number of patients experiencing a reduction in the anti-JCV antibody Index value in patients who had received at least one dose of teriflunomide during participation in the SWITCH protocol (main study).
