PG - 137-153 LID - 10.1080/1744666X.2018.1426462 [doi] AB - Although multiple sclerosis (MS) remains incurable, interferon beta (IFNbeta) has been at the forefront of treatment for many years. Different formulations of IFNbeta allow for different levels of exposure: low-dose/frequency with some agents, and high-dose/frequency with others. Areas covered: This review article discusses existing and emerging efficacy and safety data for IFNbeta in MS. Clinical evidence of IFNbeta efficacy has been generated and accumulated over many decades. During this time, key clinical trials have demonstrated the benefits of high-dose and/or high-frequency dosing of IFNbeta-1a or beta-1b, compared with lower levels of exposure, on outcome measures such as relapse rates, disability progression, disease progression and magnetic resonance imaging lesion outcomes. IFNbeta therapy is well tolerated and has one of the best characterized safety profiles of all first line therapies. The overall severity of adverse events (AEs) does not appear to be affected by different IFNbeta exposures. Typical AEs that patients may experience with IFNbeta are mild, reversible and manageable. Expert commentary: IFNbeta is one of the best characterized treatments for MS, with a large body of clinical and real-world evidence supporting the risk-benefit profile. High-dose/frequency regimens may provide better long-term outcomes.
