Sleep and body rhythm changes in children with cystic fibrosis on new treatment

Researchers want to understand how Kaftrio-Kalydeco, a newer medication for cystic fibrosis, affects children's sleep and their natural body rhythms (like being a morning or evening person). Some children with CF struggle with sleep problems and unusual sleep patterns, and doctors aren't sure whether the medication helps or changes these issues.

While this medication has helped many children breathe better and feel healthier, doctors have noticed something puzzling: some children still have sleep problems, and a small group actually experiences new sleep changes after starting treatment. This study aims to understand exactly how common these sleep issues are and whether they're connected to how the medication works in the body.
