The Newest Direct-Acting Antiviral Agents: the Final Chapter in DAA Development
- 60 Downloads
Purpose of the Review
Hepatitis C virus (HCV) therapy has improved dramatically in recent years; however, small clinical gaps remained. The recent approval of the final two antiviral regimens likely to come to clinical use addresses most unmet medical needs. The clinical trial data supporting the approval of these regimens is reviewed, highlighting how they address outstanding clinical needs and noting the very few gaps that still remain.
The approval of sofosbuvir/velpatasvir/voxilaprevir provides an excellent salvage regimen for patients who have failed prior treatment with direct antiviral agents. A 12-week course of therapy leads to sustained virological response in almost all retreatment settings. In addition, the approval of glecaprevir/pibrentasvir offers an 8-week treatment option for all non-cirrhotic treatment-naïve patients and also provides a much needed therapy for patients with chronic kidney disease and HCV genotypes other than 1 and 4.
Two newly approved regimens have been approved for HCV patients who previously failed direct antiviral therapy and patients with chronic kidney disease with genotypes other than 1 and 4.
