Maternal and Postnatal Outcomes Study (MOS): A Global Observational Registry Assessing the Safety of Elfabrio® in Women With Fabry Disease and Their Infants During Pregnancy and Breastfeeding

This study, called the Maternal and Postnatal Outcomes Study (MOS), is looking into the safety of a medicine called Elfabrio for women with Fabry disease. It focuses on women who have used Elfabrio within 30 days before pregnancy or during pregnancy and breastfeeding. Researchers want to see how these pregnancies turn out for both the mothers and their babies. They'll be checking for any health problems in the mothers and any birth defects or other issues in the newborns. It's an observation study, meaning no new treatments are given; it just collects information over 10 years to understand the real-world effects.

What is this study about?

If you are a woman with Fabry disease and are pregnant or thinking about getting pregnant, this study might be of interest to you. It's called the Maternal and Postnatal Outcomes Study (MOS) and it aims to understand how safe a medicine called Elfabrio is for expectant mothers and their babies. Doctors want to learn if using Elfabrio shortly before or during pregnancy, or while breastfeeding, has any effects on the mother's health, the pregnancy itself, or the baby's development.

This study is important because it will help doctors and patients make better decisions about treatment for Fabry disease during such a crucial time. It's not a study where you'll be given a new drug or told to change your current treatment. Instead, it's an 'observational' study. This means it simply collects information about what naturally happens to women with Fabry disease who are using or have used Elfabrio around the time of pregnancy and breastfeeding.

The study will follow women and their babies for a long time – up to 12 months after the baby is born. Researchers will look at things like how healthy the mother is, any problems during pregnancy, how the birth goes, and the baby's health in their first year, including checking for any birth defects.

Key takeaways

What does participation involve?

If you decide to take part, you or your doctor will share information about your health and your pregnancy. This information will be put into a secure online system. This can be done either during your pregnancy or after your baby is born. The researchers will collect details about your pregnancy and your baby's health from the time you enrol until your baby is 12 months old. This study is observational, meaning it won't change any of your current medical care or treatment decisions; doctors will continue to treat you as they normally would.

Potential risks and benefits

There are no direct medical benefits for you or your baby from participating in this study, as it doesn't involve new treatments. However, the information gathered will help future patients and doctors understand more about Fabry disease and Elfabrio during pregnancy and breastfeeding. There are no direct physical risks as no experimental treatments are given. Your medical information will be kept private and secure. You are free to withdraw from the study at any time without affecting your medical care.
