Summary

This study tests a triple combination medicine (VX-121/tezacaftor/deutivacaftor) in children aged 1 to 11 with cystic fibrosis who have a specific gene mutation. The goal is to see if the medicine is safe, tolerable, and works well in young kids. About 210 children will take part, and the study will measure how the drug moves in the body and its effects on sweat chloride levels, a key marker of CF.
