Primary Outcome Measures:
  • Safety as Measured by the Number of Participants With Adverse Events [ Time Frame: 28 days ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • Total Plasma Clearance [ Time Frame: 48 hours ] [ Designated as safety issue: No ]
  • Volume of the Central Compartment [ Time Frame: 48 hours ] [ Designated as safety issue: No ]
  • Intercompartmental Clearance [ Time Frame: 48 hours ] [ Designated as safety issue: No ]
  • Volume of the Peripheral Compartment [ Time Frame: 48 hours ] [ Designated as safety issue: No ]

Other Outcome Measures:
  • Blood Flow and Biomarkers of Adhesion [ Time Frame: 48 hours ] [ Designated as safety issue: No ]
    As an exploratory outcome mean change in microvascular blood flow from baseline to each time point was measured. Microvascular blood flow was also measured as microFI, perfused vessel density, and RBC velocity.
