Brief Summary

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

The purpose of this study is to evaluate the safety and tolerability of ascending intravenous (IV) and subcutaneous (SC) doses of MEDI-551 in adult subjects with relapsing forms of multiple sclerosis (MS).

Detailed Description

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

This is a Phase 1, multicenter, multinational, randomized, blinded, placebo-controlled, dose-escalation study to evaluate the safety and tolerability of IV and SC doses of MEDI-551 in adult subjects with relapsing forms of MS.
