Phase II physician-initiated clinical trial investigating the efficacy and safety of guanabenz acetate for non-alcoholic fatty liver disease associated with hypertension (G-Flash study)

Basic Information

Recruitment status Complete
Health condition(s) or Problem(s) studiedNon-alcoholic fatty liver disease/non-alcoholic steatohepatitis(NAFLD/NASH)
Date of first enrollment22/12/2021
Target sample size28
Countries of recruitment
Study typeInterventional
Intervention(s)During the treatment period, the investigational drug is orally administered to groups A and B twice daily for 16 weeks. The number of administered tablets in each group is as follows: A group: WY-8678, 4 mg/day: one tablet per session, twice a day B group: WY-8678, 8 mg/day: 2 tablets per session, twice a day

Outcome(s)

Primary OutcomePercentage of those where the liver fat content (%) measured by MRI-PDFF at 16 weeks decreased by 3.46% or more from baseline (%)
Secondary Outcome1) Amount of change and rate of change from baseline in the measured values at 16 weeks were determined. The rate of change is defined as (value at 16 weeks - baseline value) / (baseline value). The following items were measured: Percentage of subjects where the liver fat content (%) measured by MRI-PDFF at 16 weeks decreased by >= 3.46% from baseline for the 4 mg and 8 mg groups Amount of change and rate of change in liver fat content measured by MRI-PDFF Rate of change in ALT, AST, and gamma-GTP Rate of change in weight Rate of change in blood lipids (chylomicron cholesterol, chylomicron triglyceride, lipoprotein cholesterol, LDL triglyceride, VLDL cholesterol, VLDL triglyceride, free cholesterol, apoprotein A1, apoprotein B, adipsin, free fatty acid) Rate of change in insulin resistance (HOMA-IR) Rate of change in liver hardness (MRE) Rate of change of fibrosis markers (ELF score, Fibrosis-4 [FIB-4]) 2)Search for new markers related to liver disease and obesity metabolic disease 3)Occurrence rate of adverse events
