Tracking cystic fibrosis medication effects in pregnant women and babies

This is an observational study that carefully monitors women with cystic fibrosis who are pregnant and taking Kaftrio (a combination medication that helps the lungs work better) along with their newborn babies. Researchers will track how the medication affects the mother's health during pregnancy and how much of the medication passes to the baby through breastfeeding. The goal is to understand whether this medication is safe for both mother and baby during this important time.

While this medication has helped many people with cystic fibrosis breathe easier, doctors need more information about how it affects pregnant women and whether it's safe for babies when passed through breast milk. This study will help fill that knowledge gap so healthcare providers can give confident answers to women with cystic fibrosis who are planning to have children.
