About this study

Official title: A Single-Center Prospective Study Evaluating the FAST Measured Glomerular Filtration Rate (mGFR) Test™ in Adults With Preserved Kidney Function and Impaired Kidney Function With Comparison to Iohexol Clearance Methods

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).

Read the 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.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of Subjects With Adverse Events Following Administration of VFI™ in Patients With Varying Degrees of Kidney Function

    An adverse event (AE) is any untoward medical occurrence in a patient or clinical investigation subject administered a pharmaceutical product, which does not necessarily have a causal relationship with this treatment. An adverse event can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal (investigational) product, whether or not related to the medicinal (investigational) product or investigational medical device.

    Measured: Baseline through day 22
