Privigen provides immunoglobulin G (IgG) antibodies that may help block your immune system from attacking the myelin. Even so, exactly how Privigen works is not completely understood.

Two clinical studies, named PRIMA and PATH, proved that Privigen is an effective treatment for CIDP

PATH evaluated Privigen in 207 people and is the largest CIDP study to date (PRIMA studied 28 people).
