Direct antiviral agents (DAA) offer a potential cure for the disease for many patients with the hepatitis C virus (HCV).
The Food and Drug Administration (FDA) has recently approved two new DAAs, telaprevir and boceprevir, and with that clinicians must now decide who should be the first to receive this treatment. Discussion of this timely topic is now available in the June issue of
Hepatology, a journal published by Wiley-Blackwell on behalf of the American Association for the Study of Liver Diseases.
The World Health Organization (WHO) estimates up to 170,000 million individuals worldwide are infected with chronic HCV. In the U.S., HCV is the leading cause of liver-related mortality and most common cause for liver transplantation. Medical evidence has shown that for the past ten years response rates to pegylated interferon and ribavirin treatment have been stagnant, with less than half of patients achieving a sustained virologic response. Now with the introduction of new DAA therapy, it is expected to significantly improve virus clearance rates, particularly in patients with genotype 1, compared to the current standard of care.
"The availability of DAA therapy will forever change the landscape of HCV," explains Andrew Aronsohn, M.D., from the University of Chicago Medical center and co-author of the current paper. "We will now be able to cure patients of HCV disease who we were unable to cure in the past." However, as the authors note, the medical breakthrough with DAAs is coupled with resource scarcity and an equitable distribution based upon medical need is essential.
