Study of MB-102 (Relmapirazin) and the Use of the MediBeacon® Transdermal GFR Measurement System Using the TGFR Reusable Sensor With Disposable Adhesive Ring

18.6 mg/mL in a 7.0 mL volume administered by intravenous injection over 30 - 60 seconds, followed by a 10 mL normal saline flush administered intravenously over 30 - 60 seconds

On treatment day, participants had the TGFR reusable sensor with disposable adhesive ring placed on their chest, and the MediBeacon® Transdermal GFR Measurement System was initiated to collect background fluorescence. When this was completed, participants received a single dose of MB-102. Fluorescent measurements were collected for 12-24 hours. For those with significant renal compromise, fluorescent measurements were continued until the sensor no longer detected MB-102 in the body.
