Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The primary objective of this study is to explore the effects of multiple regimens of natalizumab on disease activity and safety in participants with relapsing-remitting Multiple Sclerosis (RRMS).

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a a dose and frequency (but not route of administration) blinded, prospective, randomized, dose-ranging study in patients with RRMS who have received natalizumab for at least 12 months according to the local prescribing guidelines. The study will explore dosing of natalizumab by subcutaneous and intravenous routes. Participants will be randomly assigned to 1 of 6 dosing regimens, blinded to natalizumab dose, but not route, for 60 weeks of treatment.
