Purpose of Technology

The second-wave direct-acting antivirals (DAAs) are prescribed to treat chronic hepatitis C with the objective of achieving sustained viral response and preventing harmful liver damage. These agents were developed to address the issues associated with pegylated interferon, ribavirin, and previously approved DAAs, including lack of response and relapse, resistance, poor safety profile, and burdensome treatment regimen. Second-wave DAA agents include simeprevir, sofosbuvir, and the combination of ledipasvir and sofosbuvir.

Relevant Questions

  • Does fixed-dose ledipasvir-sofosbuvir improve rates of viral response in patients with chronic HCV who have been previously treated with standard care and in those who are treatment naïve?

  • Is fixed-dose ledipasvir-sofosbuvir effective for all HCV genotypes?

  • Is fixed-dose ledipasvir-sofosbuvir safe?

  • Have definitive patient selection criteria been established for fixed-dose ledipasvir-sofosbuvir?
