Primary Outcome Measures :
  1. Incidence of Treatment-Emergent Adverse Events [ Time Frame: Up to 10 days following the final study dose ]

The clinical significance of any abnormal findings will be determined by the principal investigators. All safety data including Adverse Events (AEs), vital signs, electrocardiograms (ECGs), and physical examinations will be listed by participant.


Secondary Outcome Measures :
  1. Maximum Plasma Concentration (Cmax) for MB-102 and iohexol [ Time Frame: Pre-dose and 5, 10, 15; (± 1 or 2 min), 30, 60, 90, 120, 180, 240, 300 (±5 min), 360, 480, 600 and 720 (±10 min) minutes post dose. ]

  8. Renal clearance of MB-102 and iohexol [ Time Frame: Pre-dose and each time the participant voids up to 720 minutes post dose ]
