Conditions studied: Myasthenia Gravis, CIDP - Chronic Inflammatory Demyelinating Polyneuropathy
In brief
This is a multi-country, prospective safety study of pregnant women exposed to efgartigimod or efgartigimod PH20 SC any time within 25 days prior to conception or any time during pregnancy. Women exposed to efgartigimod or efgartigimod PH20 SC only during breastfeeding will also be eligible to enroll. Background rates of major congenital malformations (MCMs) will be obtained from populations within the same countries/regions as the countries/regions in which the efgartigimod or efgartigimod PH20 SC exposed pregnancies were reported.
