Fluorescent Probe for Real-Time Kidney Function in Critically Ill Adults
Official title: Fluorescent Probe for Assessment of Renal Elimination
Run by University of Kentucky · NCT07643467 · Data updated 2026-11-12
Aging and illness can make kidney tests less reliable, so this study tests a new real-time kidney function device to see if it matches standard methods in critically ill adults.

Is this trial a fit for you?
✓Likely a good fit
Adults 18-65 who are critically or acutely ill and currently in the ICU with stable renal function.
✕Probably not a fit
Patients with unstable kidney function (KDIGO AKI stages 1-3) or other specified exclusions may not benefit from this device.

What this trial studies
This interventional phase 4 study evaluates the tGFR device, Relmapirazin, Iohexol, and the Medibeacon tGFR monitor against traditional urine collection and creatinine-based methods. It aims to determine how well the real-time transdermal GFR measurement aligns with accepted kidney function assessments in hospitalized, acutely ill patients. Participants are adults 18-65 who are critically or acutely ill and admitted to the ICU, with stable renal function. The study explores whether real-time kidney monitoring can improve dosing of renally eliminated medications in this population.
Why it matters
Potential benefit: If successful, patients may receive more accurate, timely medication dosing and improved management of kidney function.
How similar studies have gone: Prior methods of real-time kidney assessment show promise, but this approach with a transdermal device and multiple comparators is relatively novel in acutely ill patients.
