Participant Flow

This study was conducted in cystic fibrosis (CF) participants aged 12 years or older. It was pre-specified in the protocol to combine the data from this study with study VX20-121-103 (NCT05076149) for selected outcome measures.

A total of 435 participants were enrolled in this study, of which 37 were included in the run-in period but were not dosed in treatment period. Therefore, results are presented for only 398 participants dosed in the treatment period.
