Sponsored by: Actelion

Summary

The aim of the study is to investigate the safety of the concomitant administration of ACT-334441 with cardiovascular drugs.

Clinical Details

Official title: Single-center, Open-label, Randomized, Multiple-dose, Parallel-group Study to Investigate Safety and Effects on Heart Rate, Blood Pressure, and Pharmacokinetic Interactions of ACT-334441 Combined With Calcium-channel Blocker (Diltiazem) or Beta-blocker (Atenolol) Treatment in Healthy Subjects

Study design: Allocation: Randomized, Endpoint Classification: Pharmacokinetics/Dynamics Study, Intervention Model: Parallel Assignment, Masking: Open Label

Primary outcome:

PR intervals measured by 12-lead ECG (Part A + Part B)

Heart rate (HR) measured by 12-lead ECG (PArt A + Part B)

Hourly mean heart rate (HR) measured by 24-hour Holter ECG

Secondary outcome:

Areas under the plasma concentration-time curves (AUC) for ACT-334441, diltiazem and atenolol (Part B)

Maximum plasma concentration (Cmax) for ACT-334441, diltiazem and atenolol (Part B)

Time to reach the maximum plasma concentration (tmax) for ACT-334441, diltiazem and atenolol (Part B)

Terminal half-life [t(1/2)] of ACT-334441, diltiazem and atenolol (Part B)

Trough plasma levels (Ctrough) of of ACT-334441, diltiazem and atenolol (Part B)

Number of subjects with adverse events as a measure of safety

Detailed description: The study will consist of two parts: a pilot part (Part A) that will be completed prior to the start of the main part (Part B). The Subjects who will participate in Part A are excluded from Part B.
