A Study to Evaluate the Effects of Multiple Doses of FG-4592 on the Exposure, Safety and Tolerability and Effect of Warfarin in Healthy Subjects
26 september 2014 bijgewerkt door: Astellas Pharma Europe B.V.
A Phase 1, Open-label, One-sequence Crossover Study to Evaluate the Effect of Multiple Doses of FG 4592 on the Pharmacokinetics of Warfarin in Healthy Subjects
This study will determine the effect of multiple doses of FG-4592 on the pharmacokinetics (PK) of a single dose of warfarin.
It will evaluate the safety and tolerability of warfarin alone and in combination with multiple doses of FG-4592, and will evaluate the effect of multiple doses of FG-4592 on the pharmacodynamics (PD) of warfarin.

Gedetailleerde beschrijving
The study consists of 2 periods, separated by a washout period (a minimum of 14 days after warfarin dosing on Day 1, Period 1). Screening takes place from Day -22 to Day -2.
Subjects are admitted to the clinical unit on Day -1 of Period 1. On Day 1 of the first period, subjects receive a single oral dose of warfarin. After completion of all assessments on Day 8, subjects are discharged from the clinical unit on the condition that there are no medical reasons for a prolonged stay. They return to the clinical unit on Day -1 of the second period, after the washout period.
In Period 2, the subjects receive multiple doses of FG 4592. On Day 7 of Period 2, FG 4592 is given concomitantly with warfarin. After completion of all assessments on Day 16 of Period 2, subjects are discharged from the clinic on the condition that there are no medical reasons for a prolonged stay. The subjects return for an End of Study Visit (ESV) 5 to 9 days after the last assessment of Period 2 (or after early withdrawal).
Safety assessments are performed throughout the study. Blood and urine samples are collected for PK and PD assessments.
