Samatasvir is a highly potent and selective inhibitor of the hepatitis C virus NS5A replication complex.[2] While it showed promising results when administered as monotherapy, it is probable that samatasvir would be marketed as a combination product with other anti-hepatitis drugs to increase efficacy and reduce the chance of resistance developing, as with most other novel treatments for hepatitis C currently under development. Trials of samatasvir in combination with other antiviral drugs such as simeprevir are also underway.[3]
