Intervención / Tratamiento
Descripción detallada
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

Experimental: GS-4997 + Prednisolone
GS-4997 + Prednisolone for 28 days HepQuant SHUNT Test |
Experimental drug
Control drug that is also administered with the Experimental drug, GS-4997.
This drug is used in both arms.
The HepQuant SHUNT Liver Diagnostic Kit is intended for use in the quantitative detection of 13C-cholate and d4-cholate in blood serum, collected after the intravenous administration of 13C-cholate and the oral ingestion of d4-cholate. The device is indicated to assess the severity of liver disease. For use by health care professionals. Administer the test under a physician's supervision. The HepQuant Analytical Testing Laboratory must analyze the serum samples.

¿Qué mide el estudio?
Medidas de resultado primarias
Medida de resultado |
Medida Descripción |
Periodo de tiempo |
---|---|---|
