Multiple sclerosis (MS)

 

New solutions are needed in the MS market

Understanding of the biology and importance of disability accumulation has evolved

Illustration of a human brain with text callouts: "Progression can happen independent of relapse activity"; ">80% of confirmed disability accumulation was unrelated to relapses in a study of patients with relapsing MS on treatment 2"; "Managing relapses alone is not always a complete treatment"

*A B-cell–depleting anti-CD20; relapse-independent worsening, 88% (147/167); relapse-associated worsening, 14.4% (24/167).
 

A text callout highlighting “A large proportion of people with multiple sclerosis (MS) continue to experience clinical deterioration despite a lack of overt ongoing inflammatory disease activity.... This is often referred to as progression independent of relapse activity...”

†The concepts and contents of the article by Giovannoni, et al, emerged from several meetings hosted by Sanofi Genzyme during the 2 years before its publication. Sanofi Genzyme provided financial support to help adapt and design the figures and for a third party to help coordinate the submission of the manuscript to the journal. At no stage did any staff at Sanofi Genzyme have input into the writing or editing of the article.

 

 

Each type of MS has a unique path toward irreversible disability accumulation4,5

 

 

Disability accumulation originates from 2 different processes3

 

 

Across the MS spectrum, unmet needs remain for your members

 

 

 

Current treatments may not completely impact drivers of disability accumulation15-20
