Avalglucosidase Alfa Pregnancy Study for Pompe Disease

This is an observational study looking at the safety of avalglucosidase alfa (a medicine for Pompe disease) when used during pregnancy and breastfeeding. Researchers want to understand any risks of avalglucosidase alfa for pregnant women and their babies. They will collect information on complications for the mother, the outcome of the pregnancy, and the health of the baby, including their growth and development for at least the first year of life. This study is open to women who have been exposed to avalglucosidase alfa during pregnancy or breastfeeding, and their babies. Data will be collected for about 10 years.

Study design
This is a worldwide, observational study that will collect information from 100 women and their offspring. It will look at past and future data.
