Participant Flow

This study was conducted in participants with cystic fibrosis (CF) aged 1 through less than 2 years of age who are homozygous for F508del. A total of 61 participants were enrolled in Parts A and B of the study. One participant in Part B was enrolled but not dosed in this study. Therefore, data for 60 participants are reported in the participant flow and baseline characteristics sections.

Measure
Part A: LUM/IVA
Participants weighing 7 to less than( \<)10 kilograms (kg) at screening received lumacaftor (LUM) 75 milligrams (mg)/ ivacaftor (IVA) 94 mg fixed-dose combination (FDC) every 12 hours (q12h) and those weighing 10 to \<14 kg at screening received LUM 100 mg/IVA 125 mg q12h for 15 days. Participants weighing greater than or equal to (\>=)14 kg at screening received LUM 150 mg/IVA 188 mg FDC q12h for 15 days.
Part B: LUM/IVA
Participants weighing 7 to \<9 kg at screening received LUM 75 mg/IVA 94 mg FDC q12h and those weighing 9 to \<14 kg received LUM 100 mg/IVA 125 mg q12h for 24 weeks. Participants weighing \>=14 kg at screening received LUM 150 mg/IVA 188 mg FDC q12h for 24 weeks. Doses were adjusted upwards for changes in weight.
