Multiple Sclerosis

Multiple Sclerosis (MS)

Multiple sclerosis (MS) is a complex, heterogeneous, chronic disease that requires individualized treatment throughout a patient’s life. The disease involves the central nervous system and disrupts the flow of information within the brain and between the brain and body, signaling unpredictable symptoms.1

Our Approach

Over the past four decades, Biogen has been committed to translating science to meaningful advances for the MS community. Our industry-leading portfolio — backed by established safety and efficacy profiles, ongoing investment in our products, as well as our comprehensive services and solutions — enables us to offer a broad range of options to meet the ever-evolving needs of MS patients and drive greater individualized disease management.

Innovative research

As MS disease management and patient needs evolve, Biogen remains focused on novel research initiatives and technological innovations to further the understanding of MS and improve patient outcomes. While we focus on advancing current assets in our pipeline, we aspire to pioneer disruptive therapies for MS prevention and cure through exploration in emerging science, including novel treatment approaches such as vaccine cell-based therapies, exploring new mechanisms of remyelination and neuroprotection, and developing additional preclinical models that have enhanced translational predictability.


The hidden face of MS

Imagine spending years feeling isolated and alone as you navigate a long winding road to diagnosis, searching for answers. You finally hear the words “multiple sclerosis” (MS) and although shocking, you feel some sense of relief to have an answer. But as you search for stories of others who have walked this same path, the faces staring back at you are nothing like your own. Once again, you feel isolated and alone, this time with the shame of feeling different.  

Resources for People Living With Multiple Sclerosis

Cleo™ MS Patients Companion App

Voted the No. 1 preferred app for people living with MS, the CleoTM Patients Companion App provides resources for people living with MS, such as news and information, a journal to track symptoms, exercise programs, and a nurse chat feature, with the goal of being a valuable addition to their support system.2

Clinical Trials

As pioneers in neuroscience, Biogen has an innovative therapeutic pipeline that aims to reverse disability, repair damage, and address other remaining unmet needs in MS, with the goal of significantly altering the course of MS and preventing disease development and disability progression. Biogen has active and ongoing MS clinical trials for both investigational and existing therapies. Learn more about our clinical trial recruitment and access.
