The need for all-oral HCV treatments with higher response rates, improved tolerability and lower pill burden compared to interferon-inclusive regimen has led to the development of new direct-acting antiviral agents (DAAs). Ravidasvir (RDV) is a second-generation, pan-genotypic NS5A inhibitor with high barrier to resistance. The aim of this phase 2 study (EVERST study) was to assess the efficacy and safety of interferon-free, 12-week RDV plus ritonavir-boosted danoprevir (DNVr) and ribavirin (RBV) regimen for treatment-naïve Asian HCV genotype 1 (GT1) patients without cirrhosis.
