Daclatasvir (USAN[1]) (formerly BMS-790052, trade name Daklinza) is a drug for the treatment of hepatitis C (HCV). It is was developed by Bristol-Myers Squibb and was approved in Europe on 22 August 2014.

Daclatasvir inhibits the HCV nonstructural protein NS5A.[2][3] Recent research suggests that it targets two steps of the viral replication process, enabling rapid decline of HCV RNA.[4]

Daclatasvir has been tested in combination regimens with pegylated interferon and ribavirin,[5] as well as with other direct-acting antiviral agents including asunaprevir[6][7][8][9] and sofosbuvir.[10][11]
