Numerous clinical trials spanning Early Phase 1 through Phase 4 evaluate deoxycholic acid and related bile acid regimens across metabolic and hepatobiliary conditions, including obesity, primary biliary cirrhosis, nonalcoholic steatohepatitis, transthyretin amyloidosis, toxic hepatitis, and end-stage kidney disease. Sponsored by various commercial entities and academic institutions, these studies encompass completed, active, recruiting, terminated, and withdrawn statuses. These investigations primarily assess lipid profiles, adipokine dynamics, and lipoprotein metabolism following therapeutic intervention.
