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.
