Everson and Steve M. Helmke, HepQuant, LLC, Greenwood Village, CO; University of Colorado School of Medicine, Aurora, CO.

EASL International Liver Congress: Greg Everson, MD, and Brad Everson, HepQuant’s CEO and CBDO respectively, attended the EASL International Liver Congress, April 10-14, 2019  in Vienna, Austria.

Poster: A late breaker poster was released at EASL ILC 2019 discussing baseline and Day 85 HepQuant-SHUNT™ and Disease Severity Index (DSI) results from Intercept study 747-117 conducted in parallel to the Regenerate study. “Effect of Obeticholic Acid on Liver Function in Patients With Fibrosis due to NASH.” Naim Alkhouri (1), Gregory T.

NASH-TAG Conference in Park City, Utah in January 2019

  • NASH-TAG 2019 (Poster 1): Title: Hepatobiliary and Metabolic Changes Occurring during Weight Loss and Subsequent Weight Maintenance in Obese Subjects: Implications for NASH Clinical Trials
  • NASH-TAG 2019 (Poster 2): Modeling the HepQuant STAT Test for Pre-screening NASH Subjects to Enrich Study Populations for the Desired Stage of Disease

AASLD Liver Meeting 2018: HepQuant attended the AASLD Liver Meeting in San Francisco, Nov. 9 – 13th. The company presented 2 posters:

  • Poster 1: “Defining and Monitoring Liver Disease in Chronic Hepatitis C:  A Comparison of the Disease Severity Index (DSI) from the HepQuant SHUNT test with Ishak Fibrosis (IFS) from Liver Biopsy.” Everson GT, Helmke SM.  Hepatology 2018;68:910A. Annotation: This study suggests that DSI may be more sensitive than IFS in measuring serial changes in disease in patients with chronic hepatitis C.
  • Poster 2: “Defining Disease Severity and Measuring Progression in Primary Sclerosing Cholangitis (PSC):  A Comparison of the Disease Severity Index (DSI) from the HepQuant SHUNT Test with Serum Alkaline Phosphatase (Alk Phos).”  Helmke SM, Everson GT. Hepatology 2018;1087A. Annotation: This study suggests that DSI may be more sensitive than Alk Phos in measuring serial changes in disease in patients with PSC.
