Healthy volunteers help test Easier-to-Take cystic fibrosis drug formulation

This study tested a new granule (powder) version of three cystic fibrosis drugs (vanzacaftor, tezacaftor, and deutivacaftor) in 34 healthy adults. The goal was to see how well the body absorbs the granule form, whether food changes absorption, and if different doses work as expected. Participants took the drugs once and were monitored for side effects. This early-stage research helps develop a more convenient treatment option for people with cystic fibrosis.
