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

Clinical Details

Official title: A Single-center, Open-label, Randomized, Two-way Crossover Study to Investigate the Effect of Multiple-dose Diltiazem on the Pharmacokinetics of a Single Dose of 25 mg ACT 541468 in Healthy Male Subjects

Study design: Allocation: Randomized, Endpoint Classification: Pharmacokinetics Study, Intervention Model: Crossover Assignment, Masking: Open Label

Primary outcome:

Maximum plasma concentration (Cmax) of ACT-541468

Time to reach Cmax of ACT-541468 in plasma

Area under the plasma concentration-time curve (AUC) of ACT-541468

Detailed description: 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
