Daclatasvir (trade name Daklinza) is a drug for the treatment of hepatitis C (HCV). It was developed by Bristol-Myers Squibb and was approved in Europe on 22 August 2014. Daklinza gained its FDA approval on July 24, 2015 in the United States; it is approved for hepatitis C genotype 3 infections.[1]

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]

It is on the World Health Organization's List of Essential Medicines, a list of the most important medications needed in a basic health system.[12] There has been controversy over the price that Bristol-Myers Squibb has chosen to charge for the drug. As of December 2015 it costs between $50,000 and $84,000 in high-income countries.[13] A generic version of daclatasvir was approved in India in December 2015[14] and is currently being sold under brand names NATDAC (produced by Natco Pharma) and MyDacla (produced by Mylan).[15]
