Update on disease-modifying treatments for multiple sclerosis

Abstract

Purpose: The purpose of this review is to discuss the selection and use of disease- modifying treatments for patients with relapsing forms of multiple sclerosis (MS).

Methods: PubMed was searched (1966-2014) using the terms multiple sclerosis, treatment, interferon, glatiramer acetate, dimethyl fumarate, fingolimod, teriflunomide, natalizumab, rituximab, and alemtuzumab.

Findings: MS is a chronic neurological disorder that can cause a substantial degree of disability. Because of its usual onset in young adults, patients may require treatment for several decades. Currently available agents include platform injectable therapies, newer oral agents, and second-line monoclonal antibody treatments. Treatment decisions have become more complex with the introduction of new approaches, and a major goal is to balance perceived efficacy and tolerability in a specific patient with the relative impact of disease activity and adverse events on quality of life. Here the options for disease-modifying treatments for relapsing forms of MS are reviewed, and current and future challenges are discussed.

Implications: An evidence-based approach can be used for the selection of disease-modifying treatments based on disease phenotype and severity, adverse events, and perceived efficacy.
