Primary Outcome Measures:
  • To determine the effects of steady state YM178 levels on the pharmacokinetics (PK) of a single dose of digoxin [ Time Frame: Pre-dose up to 144 hours post-dose ] [ Designated as safety issue: No ]
    Cmax (Maximum concentration), AUCinf (Area under the plasma concentration - time curve extrapolated until time = infinity)


Secondary Outcome Measures:
  • To evaluate the interaction between YM178 and digoxin in terms of safety and tolerability through assessment of adverse events, ECG and clinical laboratory assessments [ Time Frame: Baseline to Post study visit (Up to 14 days after last dose) ] [ Designated as safety issue: No ]

Enrollment: 25
Study Start Date: September 2008

Primary Completion Date: December 2008 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: YM178 OCAS + digoxin Drug: YM178 OCAS
oral
Other Names:
  • Mirabegron
  • Myrebtriq
Drug: Digoxin
oral
Other Name: Lanoxin

Detailed Description:

Subjects receive a single oral dose of digoxin on Day 1. A full pharmacokinetic profile of digoxin is obtained for up to 144 hours post-dose. On the morning of Day 7, after the scheduled assessments are done, the subjects leave the clinic and return on Day 9.

From Day 10 up to and including Day 23, subjects receive daily oral doses of YM178 q.d. A single dose of digoxin is given in combination with YM178 on Day 18 (8 days after the first dose of YM178). On this day, a complete pharmacokinetic profile for digoxin is obtained up to 144 hours post-dose.

From Day 16 up to and including Day 19, blood samples for bioanalysis of YM178 are taken regularly. In addition, vital signs, safety ECG (Electrocardiogram) measurements, safety laboratory assessments, adverse events and concomitant medications are monitored throughout the investigational period.

Subjects return for a Post Study Visit 7-14 days after the last dosing occasion.
