Evaluation of HepQuant SHUNT to Assess Liver Disease; Substudy Within GS-US-416-2124
- Conditions
- Severe Alcoholic Hepatitis
- Interventions
- Registration Number
- NCT03087968
- Lead Sponsor
- HepQuant, LLC
- Brief Summary
This clinical investigation is a substudy within GS-US-416-2124, IND 129570, which is A Phase 2, Double-Blind, Randomized Study Evaluating the Safety, Tolerability, and Efficacy of GS-4997 in Combination with Prednisolone versus Prednisolone Alone in Subjects with Severe Alcoholic Hepatitis. The use of the HepQuant SHUNT test is to assess liver disease severity before, during, and after treatment with GS-4997 or placebo, to assess liver disease severity.
- Detailed Description
The main study is a Phase 2, double blind, proof-of-concept, randomized study evaluating the safety, tolerability, and biological activity of GS-4997 in combination with prednisolone, compared to prednisolone alone, in subjects with severe, histologically-confirmed AH.
This substudy uses the HepQuant SHUNT Liver Diagnostic test to assess severity of disease at baseline and to track disease progression or improvement over the 24 weeks of the study. The HepQuant SHUNT test will be performed at baseline (Day 1) and at Weeks 1, 2, 4, 12, and 24 regardless of treatment Arm.
GS-4997 Dose and Mode of Administration. Subjects will be randomized 1:1 to either:
* Treatment Group A: GS-4997 18 mg (1 x 18 mg tablet) AND prednisolone 40 mg (4 x 10 mg tablets), both administered orally once daily
* Treatment Group B: GS-4997 placebo (1 tablet) AND prednisolone 40 mg (4 x 10 mg tablets), both administered orally once daily

- Primary Outcome Measures
Name Time Method To compare the change in (DSI ) Disease Severity Index between GS-4997 treatment and placebo arms HepQuant Shunt testing will be done at baseline (Day1), Week 1, Week 4, Week 12, Week 24 Using the SHUNT DSI to evaluate the liver, this outcome will compare the two arms to determine if SHUNT DSI is able to measure a change between the experimental and control groups.
- Secondary Outcome Measures
Name Time Method Secondary Outcome 1 HepQuant Shunt testing will be done at baseline (Day1), Week 1, Week 4, Week 12, Week 24 To determine the relationship of baseline Disease Severity Index (DSI) to mortality risk;
Secondary Outcome 2 HepQuant Shunt testing will be done at baseline (Day1), Week 1, Week 4, Week 12, Week 24 To determine the relationship of change in Disease Severity Index (DSI) to mortality risk
Secondary Outcome 3 HepQuant Shunt testing will be done at baseline (Day1), Week 1, Week 4, Week 12, Week 24 To correlate baseline Disease Severity Index (DSI) with baseline Maddrey, MELD, and Lille scorestest with the pharmacokinetics of GS-4997
Secondary Outcome 4 HepQuant Shunt testing will be done at baseline (Day1), Week 1, Week 4, Week 12, Week 24 To determine the relationship between baseline Disease Severity Index (DSI), Maddrey, MELD, and Lille scores and mortality
