Tauroursodeoxycholic Acid Combined With PD-1/PD-L1 Immunotherapy in Advanced Hepatocellular Carcinoma: A Prospective Study

Summary

This is a clinical trial that aims to evaluate whether adding a bile acid called tauroursodeoxycholic acid (TUDCA) can improve the effects of immunotherapy in patients with advanced liver cancer (hepatocellular carcinoma). Immunotherapy has shown promise in treating this type of cancer, but not all patients respond well. TUDCA is known to help protect liver cells and may improve the liver's immune environment, potentially making immunotherapy more effective. In this study, 300 patients with advanced liver cancer will be randomly assigned to receive either immunotherapy alone or immunotherapy combined with TUDCA. Researchers will look at how well the cancer responds, whether the treatment helps more patients become eligible for surgery, and how safe the combination is. The goal is to find a more effective and better tolerated treatment for patients with liver cancer.
