A Phase II Clinical Trial of Chiglitazar for NASH

The study is a non-invasive exploratory phase II trial in patients who were clinically diagnosed as non-alcoholic steatohepatitis (NASH) with liver fibrosis accompanied by elevated triglycerides (TG) and insulin resistance. The efficacy and safety of chiglitazar tablets 48mg and 64mg will be compared with placebo in the 18-week-treament.
