“More than half of the patients in the study had failed a prior course of treatment for hepatitis C infection,” said co-principal investigator Michael Curry, MD, Director of Hepatology and Medical Director of Liver Transplantation at BIDMC and Associate Professor of Medicine at Harvard Medical School. “Our trial showed that using a daily combination of the antiviral medications Sofosbuvir and Velpatasvir, with or without the addition of Ribavirin for 12 weeks or 24 weeks, successfully treated Hepatitis C in 83 percent to 94 percent of patients.”
The hepatitis C virus (HCV) infects between 130 and 150 million individuals worldwide and is a common cause of liver failure and cirrhosis, which develops when healthy liver tissue is replaced with scar tissue, eventually preventing the liver from carrying out its functions.
A total of 267 patients with liver failure caused by hepatitis C participated in the randomized Phase 3 clinical study at 47 sites across the United States.
“There have been few treatment options available for treating hepatitis C infection in patients with existing cirrhosis and liver failure,” said Curry. “Our study found that early improvements in liver function were seen in a substantial portion of the study participants, as indicated by improvement in the Childs Pugh score, which assesses severity of liver cirrhosis, and the MELD score, which is used to determine patient priority for liver transplantation.”
The liver is largest solid organ in the body and plays a number of key roles, including the manufacture of blood proteins to aid in clotting and immune system function, the manufacture of bile for the digestion of food, and the storage of energy-producing glucose. The liver also rids the body of harmful substances, such as alcohol.
“The number of patients with liver failure due to hepatitis C is expected to substantially increase over the next 10 years,” said Curry. “These new findings indicate that patients with more advanced liver disease can still benefit from treatment of hepatitis C – and that elimination of this infection is associated with early improvement in liver function.”
