Brigham and Women’s Hospital, USA: Migulstat as a therapy

Miglustat as a therapy for secondary-progressive multiple sclerosis

Astrocytes are cells in the brain that may play a destructive role in MS since among other activities, they are known to create scar tissue that may interfere with tissue repair. In the search for leads to new approaches to treating progressive MS, this team proposes to use an experimental mouse model that resembles several features of secondary-progressive MS to investigate the potential of a drug called miglustat. This drug is approved to treat other diseases, and it has been found to inhibit a protein, called “B4GALT6,” which the team found to be involved in the activation of astrocytes. The investigator proposes to test whether miglustat can inhibit astrocytes to stop disease progression. The team will also test its impact on human and mouse nerve cells isolated in the laboratory.

What does this mean for people living with progressive MS?

This study may point to a new strategy for stopping a key contributor to MS progression. Since miglustat is already is FDA-approved for other disorders, this would expedite its application to MS if it indeed proves safe and effective.

Project Update

Status: Complete

To date, in an animal model of MS, the team has found that daily administration of miglustat suppressed the clinical course of disease progression and reduced the recruitment of inflammatory  monocytes to the Central Nervous System. The data suggest that miglustat administration halts chronic EAE progression, and represents a potential therapeutic approach for progressive MS.
