Apixaban to Prevent Decompensation of Early Liver Cirrhosis Trial

Официальное название

Apixaban to Prevent dEcompensation of eArly Liver CirrHosis Trial

Обзор

Liver disease is the only common cause of death that is increasing in numbers. Once people develop severe scarring (cirrhosis), there are no medications proven to help them live longer, healthier lives. Apixaban is already commonly used to prevent or treat blood clots and is known to be safe for those with cirrhosis. In the early stages of cirrhosis, most people have no symptoms and lead normal lives; this is called "compensated" cirrhosis. However, when the liver stops working properly, they develop "decompensated" cirrhosis, which causes yellow skin, confusion, vomiting of blood and painful fluid build-up. This is serious, and people are extremely unwell with a poor quality of life, often need to go to the hospital and on average only live for 2 more years. The APEACH trial will investigate whether giving compensated cirrhosis patients Apixaban will help stop them from developing decompensated cirrhosis and stay in good health for longer. Previous research studies suggest that taking blood-thinning drugs is safe and helpful for cirrhosis. However, these did not have enough participants to be confident enough in the results to recommend use in everyday clinical care. The APEACH trial will include enough participants to make it clear whether Apixaban is helpful or not.
