About MOG‑AD

Understanding your condition

Myelin oligodendrocyte glycoprotein antibody-associated disease (MOG‑AD) is a rare inflammatory condition that affects the central nervous system. It is thought to be caused by autoantibodies, which are antibodies that mistakenly target healthy proteins in the body instead of harmful germs or viruses.

In MOG‑AD, these antibodies attack myelin oligodendrocyte glycoprotein (MOG), a protein found in the myelin, causing inflammation (or swelling) and damage.

The regions in the central nervous system usually affected in MOG‑AD are:

The optic nerves
(nerves involved in vision)

The spinal cord

The brain

The cosMOG study will work to find out if an investigational drug can prolong the time between relapses of inflammation.

About the cosMOG study

The cosMOG study aims to understand how well-tolerated and effective an investigational drug called rozanolixizumab is in people with MOG‑AD. The investigational drug will be given weekly as an infusion under the skin.

With no approved treatment options for MOG‑AD, we understand that your treatment journey may not have been an easy one. Clinical research studies, also called clinical trials, are a necessary and vital step toward understanding rare diseases such as MOG‑AD and how to treat them.

With your help, the cosMOG study will evaluate if an investigational drug can prolong the time between relapses for people with this condition.
