Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Because ACT-541468 appears to be mainly metabolized by CYP3A4, it is deemed of interest to investigate the potential influence of diltiazem, a well-known CYP3A4 inhibitor on the pharmacokinetic profile of ACT-541468.

Safety of the concomitant administration of the two drugs will also be assessed
