Vaccination Response in Tecfidera-Treated Versus Interferon-Treated Participants With Relapsing Forms of Multiple Sclerosis.
Relapsing Forms of Multiple Sclerosis

About this trial
This is an interventional treatment trial for Relapsing Forms of Multiple Sclerosis focused on measuring vaccine, pneumococcal, meningococcal, tetanus diphtheria, immune response
Eligibility Criteria
Key Inclusion Criteria:
- Must have a confirmed diagnosis of relapsing remitting MS per the 2010 McDonald criteria.

- Must have been on a stable approved dose of Tecfidera (240 mg twice daily [BID]) [Group 1] for ≥6 months or on a stable approved dose of a non-pegylated IFN (e.g., Avonex, Betaseron, Rebif, Extavia) [Group 2] for ≥3 months prior to Day 1.
Key Exclusion Criteria:
- Clinical relapse requiring treatment within 30 days prior to Day 1.
