DAAs reduce mortality, cancer risk in HCV study

This study provides “substantive evidence” that curing hepatitis C virus with all-oral direct-acting antiviral regimens provides clinical benefits, according to Raymond T. Chung, MD, and his coauthors of a related editorial.

Investigators in this study provide the best evidence so far in support of guidelines that advise direct-acting antiviral (DAA) treatment for all patients with chronic hepatitis C virus (HCV) infection, the editorial’s authors stated.

Results of the French study provide a strong counterpoint to the findings of a recent Cochrane review of DAA trials that could not confirm or reject whether DAAs had effects on long-term morbidity and mortality related to HCV, added Dr. Chung and his coauthors. “Finally, they provide credence to the achievability of the goals set out by the World Health Organization (WHO), not only to eliminate HCV but also to substantially reduce its complications.”

The WHO targets were established in light of earlier evidence that sustained virologic responses are linked to reductions in hepatocellular carcinoma, liver transplantation, and mortality, they said.

“In view of the high sustained virological response and excellent tolerability achieved with DAAs, it seemed highly plausible to envision reductions in chronic HCV infection–related complications with these drugs,” they said in reference to the study by Carrat and colleagues.
