Given the rapidly evolving hepatitis C (HCV) treatment landscape in the U.S., Bristol-Myers Squibb has decided that it will not pursue U.S. Food and Drug Administration (FDA) approval of the dual regimen of daclatasvir and asunaprevir for the treatment of HCV genotype 1b patients in the United States and has therefore withdrawn its new drug application (NDA) for asunaprevir, an NS3/4A protease inhibitor. The company will continue to pursue FDA approval of daclatasvir, a potent, pan-genotypic NS5A complex inhibitor (in vitro), which is currently being investigated globally in multiple treatment regimens for HCV patients with high unmet need.

Bristol-Myers Squibb’s HCV strategy has always been to focus on the unique unmet medical need of each local market. For example, in Japan we were pleased to receive regulatory approval for the dual regimen of daclatasvir and asunaprevir in July, bringing Japanese patients with HCV the first all-oral, interferon- and ribavirin-free treatment regimen.
