Assessment

Primary outcomes

1) Dosing pattern of NTZ
2) Annual relapse rate (ARR) by NTZ dosing pattern

Key secondary outcomes

1) The following effectiveness end points will be evaluated by NTZ dosing patterns and in overall patients
- Cumulative incidence of relapse
- Time to first relapse after initial NTZ treatment
- Proportions of patients with and without relapse
- Disability progression as determined by EDSS: disability progression over time, EDSS change from baseline, and proportions of patients with disease progression and improvement
- Number of new or enlarged T2/FLAIR, and Gd+ lesions using MRI
2) No evidence disease activity (NEDA-3)
3) Comparison of ARR before and after NTZ treatment in overall patients
4) Comparison of ARR during SID and after switching to EID in patients with SID/EID
5) Comparison of ARR during SID and after switching to EID in patients with SID/EID who received initial NTZ treatment after January 2018
6) Information on NTZ discontinuation (number of patients, treatment pattern before discontinuation, duration of treatment, and reason for discontinuation)
7) Anti-JCV antibody (percentage of anti-JCV-positive and -negative patients, seroconversion rate, and change in JCV index)
