FDA issues Complete Response Letter for daclatasvir for treatment of Hepatitis C- BMS
BMS has announced that the FDA has issued a Complete Response Letter (CRL) regarding the New Drug Application (NDA) for daclatasvir, an NS5A complex inhibitor, in combination with other agents for the treatment of Hepatitis C (HCV).
The initial daclatasvir NDA submitted to the FDA focused on its use in combination with asunaprevir, an NS3/4A protease inhibitor. Given the withdrawal of asunaprevir by Bristol-Myers Squibb in October, the FDA is requesting additional data for daclatasvir in combination with other antiviral agents for the treatment of HCV. Bristol-Myers Squibb is in discussions with the FDA about the scope of these data.
