Brief Summary

This study was a pilot, safety, and pharmacokinetic study of MB-102 versus iohexol and the use of the non-invasive optical renal function monitor (ORFM) device in normal and compromised renal function participants with different skin color types.

Detailed Description

The objectives of this study were to evaluate the safety and tolerability of single and multiple doses of MB-102 in participants with normal and impaired kidney function; to determine plasma pharmacokinetics of MB-102 compared to the pharmacokinetics of iohexol in participants with normal and impaired kidney function; to demonstrate that MB-102-transdermal-fluorescence-measured glomerular filtration rate (GFR) using the optical renal function monitor (ORFM) Brilliance device is aligned with MB-102 plasma GFR; to evaluate the safety and effectiveness of the ORFM investigational medical device prototypes QuantumLeap, Radiance, and Brilliance for the non-invasive transdermal fluorescent detection of MB-102 in participants with a range of skin color types; and to determine the optimal dose of MB-102 for non-invasive measurement.
