a study to evaluate the safety, tolerability, pharmacokinetics and pharmacodynamics of orally administered gb1211 in participants with suspected or confirmed non-alcoholic steatohepatitis (nash) and liver fibrosis

Conditions: Non-alcoholic Steatohepatitis (NASH)

Summary: this study is a randomised, double-blind, placebo controlled, phase ib trial in subjects with suspected or confirmed non-alcoholic steatohepatitis (nash) and liver fibrosis

this study is designed to evaluate the safety, tolerability, pharmacokinetics and pharmacodynamics of orally administered gb1211 a gelectin-3 inhibitor over 12 weeks. participants will receive two doses of gb1211, each given twice per day and compared to placebo in participants with fibrotic nash
