Part A: Single Ascending DoseVX-973Participants will be randomized to receive a single dose of VX-973 under fasted conditions.
Placebo Part APlaceboParticipants will be randomized to receive placebo matched to VX-973.
Placebo Part BPlaceboParticipants will be randomized to receive placebo matched to VX-973. Midazolam is planned to be administered as single oral doses of 2 mg first alone on Day -1 and then co-administered with placebo matched to VX-973 on Day 27.
Part B: Multiple Ascending DoseVX-973Participants will be randomized to receive multiple doses of VX-973 under fasted conditions. The dose and frequency will be determined based on Part A. Midazolam is planned to be administered as single oral doses of 2 mg first alone on Day -1 and then co-administered with study drug on Day 27.
Part B: Multiple Ascending DoseMidazolamParticipants will be randomized to receive multiple doses of VX-973 under fasted conditions. The dose and frequency will be determined based on Part A. Midazolam is planned to be administered as single oral doses of 2 mg first alone on Day -1 and then co-administered with study drug on Day 27.
