Insights
Hepatitis C virus (HCV) patients with cirrhosis need effective antiviral treatments. Direct-acting antiviral agents (DAAs) have improved cure rates, but challenges remain for those with advanced liver disease.
Area of Science:
- Hepatology
- Virology
- Pharmacology
Background:
- Patients with cirrhosis infected with hepatitis C virus (HCV) require effective antiviral therapy.
- Virologic cure in these patients can improve fibrosis, enhance quality of life, and reduce liver-related complications.
- Direct-acting antiviral agents (DAAs) have significantly increased cure rates for HCV genotype 1 infection.
Purpose of the Study:
- To review the available data on HCV treatment in patients with cirrhosis.
- To describe the evolution of HCV therapy from older treatments to the current era of DAAs.
Main Methods:
- Review of published phase III direct-acting antiviral (DAA) trials.
- Examination of data specifically pertaining to patients with cirrhosis.
Main Results:
- Direct-acting antiviral agents (DAAs) have revolutionized HCV treatment, increasing cure rates.
- Patients with advanced fibrosis or cirrhosis represent a challenging-to-treat population.
- Existing DAA trial data for cirrhotic patients is limited.
Conclusions:
- The advent of DAAs marks a new era in HCV therapy for patients with cirrhosis.
- Further examination of DAA efficacy and safety in cirrhotic patients is warranted.
- Understanding treatment evolution is crucial for optimizing care in this population.
Abstract:
Patients with cirrhosis who are infected with hepatitis C virus (HCV) are the most in need of antiviral treatment. Virologic cure improves fibrosis and quality of life while reducing liver-related morbidity and mortality. In mid-2011, the addition of direct-acting antiviral agents (DAAs)-the protease inhibitors boceprevir (Victrelis, Merck) and telaprevir (Incivek, Vertex)-to pegylated interferon α-2a/b and ribavirin revolutionized the treatment of HCV infection by increasing cure rates across all fibrosis scores in patients with genotype 1 HCV infection. However, patients with advanced fibrosis or cirrhosis are the most difficult to treat, and the addition of DAAs increases treatment side effects as well as potency. Five phase III DAA trials have been published to date, but they contain limited data on patients with cirrhosis. This review will examine the available data and will describe the evolution of HCV therapy in patients with cirrhosis from the standard-of-care therapy of the past decade into the new era of DAAs.
