Abstract:

Background: In the 1990s, the beta interferons and glatiramer acetate were introduced for treating relapsing-remitting multiple sclerosis. These medications have a demonstrated record of efficacy and safety, although they require frequent administration via injection and are only partially effective. The optimization of treatment in patients who do not respond adequately to this first-line therapy is essential for attaining the best long-term outcomes. Switching to the recently approved emergent therapies is a strategy to consider for treatment of patients with a suboptimal response.

Objective: This review summarizes the mechanisms of action, clinical benefits, and safety profiles of current multiple sclerosis disease-modifying therapies, including highly efficacious monoclonal antibodies or convenient oral therapies, and with a special focus on the pegylated interferon beta 1a formulation.

Methods: We reviewed the recent literature and human clinical trials on multiple sclerosis therapies by bibliographic search in PubMed and clinicaltrials.gov.

Results and Conclusion: Although the first-line interferon beta exhibits a favorable benefit-torisk profile, treatment compliance is compromised potentially due to its known adverse events and frequent injectable administration. Less frequent dosing and improved pharmacological properties have been achieved by reaction of interferon beta with chemically activated polyethylene glycol. Provided that none of the available therapies show better effectiveness for all outcomes and their safety in clinical practice is of a fundamental concern, the pegylated form of interferon beta seems to keep its place as a competitive therapeutic option.

Keywords: Pegylated interferon beta, PEG-IFN-β, multiple sclerosis, emergent therapies, treatment strategies, therapy optimization, management of MS patients.
