Primary Outcome Measures:
  • safety and tolerability [ Time Frame: 7 days ] [ Designated as safety issue: Yes ]
    Summary statistics for SAD parts will be prepared for measured values and changes from baseline values for each dose group. Placebo subjects will serve as the control. Summaries of treatment-emergent and clinically important abnormalities in ECG, physical examination, vital signs, and laboratory (clinical chemistry, hematology, coagulation, urinalysis) data will be provided. The incidence of adverse events(AEs) will be tabulated and compared across dose group in the SAD parts.
