Multiple Sclerosis study: Clemastine Fumarate

Official title Assessing Changes in Multi-parametric MRI in MS Patients Taking Clemastine Fumarate as a Myelin Repair Therapy

ClinicalTrials.gov ID: NCT05359653

What this study is testing

What is Clemastine Fumarate?

Clemastine Fumarate is an investigational medicine, taken by mouth, being studied as a potential treatment for multiple sclerosis (ms).

Also referred to as Clemastine, Dayhist.

Plain-language explanation of the investigational treatment. It is being studied and is not an approved or proven therapy. The study team can confirm the details.

What it's testing
This study is testing whether clemastine fumarate can repair damaged brain tissue in people with relapsing‑remitting multiple sclerosis. It looks at changes seen on special MRI scans.
Who it's for
You may be able to join if you have relapsing‑remitting multiple sclerosis and have chronic brain lesions.
What's involved
You would take clemastine fumarate pills at home. You will have MRI scans and eye tests at several visits to see if the brain changes.
Time commitment
The study lasts about 12 months and includes several clinic visits and MRI scans.
  • Phase 2: a mid-size study of how well it works
  • Which group you join is decided by chance.
