Primary Outcome Measures:
  • The amount of radioactivity recovered in urine and feces, as a percent of the dose. [ Time Frame: 7 weeks ] [ Designated as safety issue: No ]
  • The amount of PF-00868554, expressed as a percent of total radioactivity, in plasma, urine, and feces. [ Time Frame: 7 weeks ] [ Designated as safety issue: No ]
  • Identification and determination of relative abundance of the metabolites of PF-00868554 in plasma, urine, and feces. [ Time Frame: 7 weeks ] [ Designated as safety issue: No ]
  • PK parameters: AUClast, AUCinf, maximum concentration (Cmax), time of maximum concentration (Tmax), and half-life (t1/2) to describe the single dose PK of a) total radioactivity in blood; b) total radioactivity in plasma; c) PF-00868554 in plasma. [ Time Frame: 7 weeks ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Safety endpoints including adverse events, clinical laboratory tests, vital signs and ECGs. [ Time Frame: 7 weeks ] [ Designated as safety issue: Yes ]
