Clinical pharmacology

Interaction study with warfarin in healthy male subjects

Trial purpose

The primary objective of this study was to investigate the influence of multiple doses of 10 mg vericiguat once daily on the pharmacokinetics (R- and S-warfarin) and pharmacodynamics (clotting parameters) of a single oral dose of 25 mg warfarin, administered on the sixth day of treatment.

The secondary objective of this study was to assess the influence of multiple doses of 10 mg vericiguat once daily on the safety and tolerability of a single oral dose of warfarin.
