Clinical Trial Summary

The purpose of this study is to validate the Disease Severity Index (DSI) from the HepQuant SHUNT Liver Diagnostic Kit (Test) for likelihood of large esophageal varices.

Description:

The purpose of this study is to validate the Disease Severity Index (DSI) from the HepQuant SHUNT Liver Diagnostic Kit (Test) for likelihood of large esophageal varices. Our HALT-C Training dataset demonstrated that the DSI 18.3 had sensitivity 95%, specificity 54%, PPV 19%, NPV >99%, negative likelihood ratio (NLR) 0.09, and positive likelihood ratio (PLR) 2.09 for large varices. To validate DSI 18.3 as a cutoff for large varices, we will enroll 420 subjects with chronic liver disease (CLD) of mixed etiologies from 15 to 25 US clinical centers (CLD Validation dataset). The target prevalence of large varices is ≥20%. Each subject will have been scheduled for an esophago-gastro-duodenoscopy (EGD) as part of their standard of care for either variceal or non-variceal indications. Enrolled subjects will undergo standard clinical assessment, laboratory tests, and the HepQuant SHUNT Test. The EGD will be performed within 6 weeks following the HepQuant SHUNT Test. The relationship of DSI to large varices will be analyzed by univariate and multivariate logistic regression analyses, AUROC, and linear and nonlinear regression and correlation coefficients. Diagnostic performance of the DSI cutoff will be defined in the CLD Validation dataset and validated for likelihood of large esophageal varices. The validated DSI cutoff will identify subjects who are either unlikely or likely to have large esophageal varices.

Intervention

Combination Product:
• HepQuant SHUNT Liver Diagnostic Test
One time testing using the HepQuant SHUNT Liver Diagnostic Test kit (the combination product) in subjects with CLD and undergoing a standard of care EGD. The SHUNT test will be completed prior to the EGD. Each subject will receive an IV push dose of 13C Cholate mixed with Albumin simultaneously with an oral dose of d4 Cholate
