Executive Summary
Obeticholic acid (OCA) is a potent FXR agonist approved for treating primary biliary cholangitis (PBC) in patients who do not respond adequately to ursodeoxycholic acid (UDCA). Originally developed by Intercept Pharmaceuticals, OCA holds promise beyond its initial indication, with ongoing research exploring its potential in NASH (non-alcoholic steatohepatitis), primary sclerosing cholangitis (PSC), and other liver diseases.
This report analyzes the current market landscape, competitive environment, regulatory approvals, and financial prospects of OCA. It highlights the influence of clinical trials, patent landscapes, pricing strategies, and future market opportunities while offering insights into potential growth trajectories.
