AASLD 2014: Sofosbuvir/ Ledipasvir Cures Most Previously Treated HCV Patients with Cirrhosis

Difficult-to-treat hepatitis C patients with liver cirrhosis who were not cured with a prior course of therapy with first-generation HCV protease inhibitors had a sustained virological response rate of 97% when retreated with sofosbuvir/ledipasvir (Harvoni) for 24 weeks, researchers reported at the American Association for the Study of Liver Diseases (AASLD) Liver Meeting last month in Boston.

AASLD 2014: DAAs Show Good Cure Rates and Liver Function Improvement for Transplant Recipients with Recurrent HCV

A variety of interferon-free regimens containing the direct-acting antivirals sofosbuvir (Sovaldi), simeprevir (Olysio), and daclatasvir (Daklinza) led to high sustained virological response rates, often improved liver function, and were generally safe and reasonably well-tolerated by liver transplant recipients with hepatitis C recurrence, one of the most difficult populations to treat, according to several presentations at the American Association for the Study of Liver Diseases (AASLD) Liver Meeting this month in Boston.
