Primary Outcome Measures:
  • Cmax of digoxin assessed by its plasma concentration change [ Time Frame: for 24 hour after the last dose of each period ]
  • AUC of digoxin assessed by its plasma concentration change [ Time Frame: for 24 hour after the last dose of each period ]

Secondary Outcome Measures:
  • Changes in the blood coaggregation indexes such as PT(INR), aPTT and FXa [ Time Frame: before dosing and 5hr after dosing on days 4 and 8 and 24h and 48h after the last dose ]
  • Safety assessed by the incidence of adverse events, vital signs, 12-lead ECG and labo-tests [ Time Frame: for 10 days after dosing ]

Enrollment: 24
Study Start Date: February 2006
Study Completion Date: April 2006
Primary Completion Date: April 2006 (Final data collection date for primary outcome measure)

Detailed Description:

The study will be of a double blind, randomized, two period crossover design. Two treatments, digoxin in combination with YM150, and digoxin in combination with placebo, will be evaluated. Each subject will receive both treatments in random order. Placebo will be used to maintain the blind. Males and females will be equally divided over the treatment orders.

Subjects will be dosed with digoxin and either YM150 or placebo for 8 days to reach steady state. In the second period the subjects will receive digoxin and the alternate treatment. There will be a washout period of at least 10 days between the consecutive treatments. In both study periods the subjects will be admitted the day prior to study drug administration (Day 0). The subjects will be discharged on Day 10. Approximately one week after the last discharge, the subjects will return to the unit for a post study visit.
