An Open Label, Single-Center, Safety and Pharmacokinetic Study of Lumitrace® Injection (Relmapirazin) and the Use of the MediBeacon® Transdermal GFR System Using the TGFR Reusable Sensor With TGFR Disposable Ring for the Evaluation of Kidney Function in Patients With Heart Failure
MediBeacon
Summary
The goal of this clinical trial is to evaluate the accuracy and feasibility of transdermal glomerular filtration rate (tGFR) assessment using relmapirazin (Lumitrace) and the MediBeacon tGFR system compared to plasma clearance measurement of GFR in adults with heart failure. The main question it aims to answer is the comparison of the transdermal-derived GFR for each participant using the MediBeacon tGFR to their nGFRBSA measurement. Participants will participate in a Screening visit that will take place within 15 days of the scheduled administration of Lumitrace and iohexol. On dosing day, participants will have the tGFR reusable sensor with disposable adhesive ring placed on their chest, and the MediBeacon Transdermal GFR System initiated to collect background fluorescence. Following an injection of Lumitrace and iohexol and the initiation of GFR assessments, participants will be followed at the study center for 10-24 hours. All participants will participate in a follow-up phone call approximately 7 days after the last exposure to Lumitrace and iohexol. Researchers will analyze the results to compare the tGFR values to the nGFRBSA measurements for each participant.

Interventions
- DeviceLumitrace
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
- DeviceMediBeacon Transdermal Glomerular Filtration Rate Measurement System (tGFR)
Site staff will place and affix the tGFR reusable sensor and Disposable Ring for all enrolled participants. One sensor will be attached to the upper chest. An adhesive clip, surgical tape or other means may also be used to alleviate tension on the sensor cord. TGFR assessments will be collected for a minimum of 6 hours up to 8 hours post Lumitrace injection.
- DrugIohexol
1.5 mL of a 647 mg/mL solution administered by intravenous injection over 30 seconds, followed by a 10 mL normal saline flush administered intravenously over 30 -60 seconds
