Group Intervention Description Part A VX-548 Participants will receive a single dose of VX-548 on Day 1 and a single dose of omeprazole once daily (qd) on Days 10 through Day 12. On Day 13, participants will receive omeprazole followed by VX-548 under fasted conditions. Part B VX-548 Participants will receive a single dose of VX-548 on Day 1 followed by rifampin qd on Days 10 through Day 27. On Day 19, participants will be co-administered rifampin and VX-548 under fasted conditions. Part A Omeprazole Participants will receive a single dose of VX-548 on Day 1 and a single dose of omeprazole once daily (qd) on Days 10 through Day 12. On Day 13, participants will receive omeprazole followed by VX-548 under fasted conditions. Part B Rifampin Participants will receive a single dose of VX-548 on Day 1 followed by rifampin qd on Days 10 through Day 27. On Day 19, participants will be co-administered rifampin and VX-548 under fasted conditions.
