Brief summary

The primary objective of this study is to describe the frequency and characteristics of pregnancy outcomes and maternal complications among participants exposed to Ultomiris and to describe the frequency and characteristics of selected fetal/neonatal/infant outcomes in utero, at birth, and through 1 year of age after exposure in utero or via breastmilk.

Detailed description

This observational study will collect prospective and retrospective data in participants exposed to Ultomiris during pregnancy and/or breastfeeding to assess risk of maternal complications, adverse effects on the developing fetus, and adverse effects on the infant.
