Further study details as provided by Astellas Pharma Inc:

Primary Outcome Measures:
  • Maximum plasma concentration (Cmax) of YM178 [ Time Frame: Up to 96 hrs post dose ]
  • AUC (area under the curve) of YM178 plasma concentration [ Time Frame: Up to 96 hrs post dose ]

Secondary Outcome Measures:
  • tmax of YM178 plasma concentration [ Time Frame: Up to 96 hrs post dose ]
  • t1/2 of YM178 plasma concentration [ Time Frame: Up to 96 hrs post dose ]
  • Safety assessed by the incidence of adverse events, clinical lab tests, vital signs, 12-lead ECGs and physical exam. [ Time Frame: Up to 96 hrs post dose ]
