Brief summary

This is a single site study designed to evaluate the FAST mGFR Test™ in healthy adult volunteers, patients with varying degrees of chronic kidney disease (CKD), and patients with acute kidney injury (AKI).

Detailed description

A rapid and accurate measurement of glomerular filtration rate (GFR) is important in acute kidney injury (AKI) and chronic kidney disease (CKD) for assessment of impairment, diagnosis, and prompt treatment. FAST BioMedical is an emerging technology company whose mission is to quantify clinically meaning ful physiological parameters that have been difficult or impossible to measure. GFR is the most clinically relevant metric for understanding renal function, as it is the rate by which the kidney is able to filter waste products in the bloodstream. The FAST mGFR is for direct measurement of GFR that relies on reading the ratio of fluorescent markers attached to different size dextran molecules introduced into the bloodstream. The test is intended as an adjunct to current methods utilized to assess kidney function.

Interventions

DEVICE75 mg / 6 mL VFI™

Visible fluorescent injectate, a mixture of two different molecular weight carboxymethyl dextran molecules (5 kD and 150 kD) with different fluorescent dye molecules attached.

Tmax of FD001 and FD003 Following Administration of VFI™ in Patients With Varying Degrees of Kidney Function

Tmax = time of maximum observed concentration

Time frame: PK parameters were evaluated using samples collected pre and post dose at day 2, as well as post dose on days 4, 8, 15, 22.

Population: Intent-to-treat subject population analyzed. PK was not evaluated in Cohort 1 due to a contamination problem caused by the sample collection catheter used in this cohort. In addition, PK data was not collected for the single subject dosed in Group 4.

To Compare the Results From the GFR Determined From the FAST VFI™ to GFR Derived From Iohexol Clearance Methods.

This analysis will compare estimates of kidney function derived from the results of FAST VFI™ to those derived through conventional Iohexol clearance methods.

Time frame: Baseline through Day 22

Population: The subject in Cohort 4 did not receive Iohexol. One subject in Cohort 5 withdrew from the study before receiving Iohexol. Samples were missing for 1 subject in each of Cohorts 1 and 3.
