Primary Outcome Measures:
  • Incidence and severity of adverse events [ Time Frame: 5 months ] [ Designated as safety issue: Yes ]
  • Incidence and severity of clinical findings on physical examination [ Time Frame: 5 months ] [ Designated as safety issue: Yes ]
  • Mean change from baseline in vital signs (blood pressure, pulse rate, oral or tympanic temperature) measurements [ Time Frame: 5 months ] [ Designated as safety issue: Yes ]
  • Mean change from baseline in 12-lead electrocardiogram (ECG) parameters: PRI, RR, QRS, QT, QTcF (Freidericia's correction) and HR (heart rate) [ Time Frame: 5 months ] [ Designated as safety issue: Yes ]
  • Serum PF-04236921 concentrations will be determined by a validated assay and noncompartmental PK parameters [ Time Frame: 5 months ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Incidence and severity of clinical laboratory abnormalities including absolute neturophil count, hepatic transaminases and bilirubin levels, and lipid profiles [ Time Frame: 5 months ] [ Designated as safety issue: Yes ]
  • Incidence and level of ADA development [ Time Frame: 5 months ] [ Designated as safety issue: Yes ]
