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.
