Primary Outcome Measures:
  • Change From Baseline in Hepatic Venous Pressure Gradient (HVPG) at 0.5, 1, and 1.5 Hours Post Dose [ Time Frame: Baseline and 0.5, 1, and 1.5 hours post dose ]

    Change from baseline is calculated as time point minus baseline.

    Baseline procedures were performed prior to study drug administration.


  • Change From Baseline in Hepatic Blood Flow (HBF) at 0.5, 1, and 1.5 Hours Post Dose [ Time Frame: Baseline and 0.5, 1, and 1.5 hours post dose ]

    Change from baseline is calculated as time point minus baseline.

    Baseline procedures were performed prior to study drug administration.


  • Change From Baseline in Hepatic Mean Arterial Pressure (MAP) at 0.5, 1, and 1.5 Hours Post Dose [ Time Frame: Baseline and 0.5, 1, and 1.5 hours post dose ]

    Change from baseline is calculated as time point minus baseline.

    Baseline procedures were performed prior to study drug administration.


  • Change From Baseline in Blood Pressure at 0.5, 1, 1.5, 2.5, 3.5, 4.5, 5.5, 6.5, 9, 12, and 24 Hours, and Day 8 Post Dose [ Time Frame: Baseline and 0.5, 1, 1.5, 2.5, 3.5, 4.5, 5.5, 6.5, 9, 12, and 24 hours, and Day 8 post dose ]

    Change from baseline is calculated as time point minus baseline.

    Baseline procedures were performed prior to study drug administration.


  • Change From Baseline in Heart Rate at 0.5, 1, 1.5, 2.5, 3.5, 4.5, 5.5, 6.5, 9, 12, and 24 Hours, and Day 8 Post Dose [ Time Frame: Baseline and 0.5, 1, 1.5, 2.5, 3.5, 4.5, 5.5, 6.5, 9, 12, and 24 hours, and Day 8 post dose ]

    Change from baseline is calculated as time point minus baseline.

    Baseline procedures were performed prior to study drug administration.



Secondary Outcome Measures:
  • Change From Baseline in Serum Sodium Levels at 0.5, 1, 2.5, 4, 6.5, 9, 12, and 24 Hours and on Day 8 Post Dose [ Time Frame: Baseline and 0.5, 1, 2.5, 4, 6.5, 9, 12, and 24 hours and on Day 8 post dose ]

    Baseline serum sodium value is the last measurement prior to dosing.

    Change from baseline is calculated as time point minus baseline.
