  • Experimental treatment arm 1

Subjects randomized to study drug will take 600 mg of lumacaftor once daily (qd) and 250 mg of ivacaftor every 12 hours (q12h)

  • Experimental treatment arm 2

Subjects randomized to study drug will take 400 mg of lumacaftor every 12 hours (q12h) and 250 mg of ivacaftor every 12 hours (q12h)

  • Experimental treatment arm 3

Subjects randomized to placebo will remain on placebo through 24 weeks. Subjects will be given tablets that match both lumacaftor and ivacaftor and will follow the same dosing regimen as subjects receiving the study drug
