Brief Summary
The main objective of this study is to investigate whether repeated administration of a cardiac medication (diltiazem) can affect the pharmacokinetics (i.e., amount and time of presence in the blood) of ACT-541468

Outcome Measures
Primary Outcomes (3)
Maximum plasma concentration (Cmax) of ACT-541468
Cmax will be directly derived from the plasma concentration time curves of ACT-541468
From baseline to end of study (Day 8 after last study drug intake for sequence AB, Day 5 after last study drug intake for sequence BA)
Time to reach Cmax of ACT-541468 in plasma
tmax will be directly derived from the plasma concentration time curves of ACT-541468
From baseline to end of study (Day 8 after last study drug intake for sequence AB, Day 5 after last study drug intake for sequence BA
Area under the plasma concentration-time curve (AUC) of ACT-541468
AUC will be calculated for the following time frame: from time zero to the last measured concentration above the limit of quantification and from time zero to infinitiy
From baseline to end of study (Day 8 after last study drug intake for sequence AB, Day 5 after last study drug intake for sequence BA)
Other Outcomes (2)
Incidence of safety events of interest
From baseline to end of study (Day 8 after last study drug intake for sequence AB, Day 5 after last study drug intake for sequence BA)
Incidence of adverse events
From baseline to end of study (Day 8 after last study drug intake for sequence AB, Day 5 after last study drug intake for sequence BA)
Study Arms (2)
Sequence AB
EXPERIMENTALDuring Period 1, subjects receive a single dose of ACT-541468 on Day 1. During Period 2, they receive Diltiazem from Day 1 to Day 7 and a single dose of ACT-541468 on Day 4
Sequence BA
EXPERIMENTALDuring Period 1, subjects receive Diltiazem from Day 1 to Day 7 and a single dose of ACT-541468 on Day 4. During Period 2, they receive a single dose of ACT-541468 on Day 1
