Daclatasvir directly blocks replication of HCV by interfering with a
hepatitis C virus protein called nonstructural protein 5A (NS5A). Daclatasvir
interferes with proteins and processes needed by hepatitis C virus to multiply
and make new viruses, thus reducing the overall viral load. The efficacy of
Daclatasvir has been established in subjects with hepatitis C virus genotypes 1
and 3.
Daclatasvir is given with sofosbuvir and may be administered with or without
ribavirin. In clinical studies, 95% of patients were cured after 12 weeks of

defined as undetectable levels of hepatitis C virus in the blood when measured
three months after the completion of treatment.
