BMS Submits NDAs for Daclatasvir and Asunaprevir to US FDA for the Treatment of Hepatitis C

Bristol-Myers Squibb Company has submitted new drug applications (NDAs) with FDA for the investigational products daclatasvir (DCV), an NS5A replication complex inhibitor, and asunaprevir (ASV), a NS3 protease inhibitor.

The data submitted in the NDAs support the use of DCV+ASV in patients with genotype 1b hepatitis C (HCV). The DCV NDA also seeks approval for use of this compound in combination with other agents for multiple genotypes. The submissions are subject to FDA review for acceptance for filing.

“These FDA submissions represent a major step towards offering daclatasvir-based regimens to US HCV patients, many of whom continue to have high unmet medical needs,” said Brian Daniels, MD, senior vice president, Global Development and Medical Affairs, Research and Development, Bristol-Myers Squibb. “We are excited to have achieved this milestone and, looking forward, will continue to innovate and invest in daclatasvir in a range of patient types and regimens.”

These submissions follow the recent announcement that the FDA granted the investigational DCV Dual Regimen (DCV+ASV) Breakthrough Therapy Designation. In 2013, the investigational all-oral 3DAA Regimen (daclatasvir/asunaprevir/BMS-791325) also received Breakthrough Therapy Designation, and the company anticipates submitting this regimen for FDA review in Q1 2015.

In January 2014, the European Medicines Agency (EMA) validated the company’s marketing authorization application for the use of DCV in combination with other agents for the treatment of adults with HCV with compensated liver disease, including genotypes 1, 2, 3, and 4, and this application is under accelerated review. In addition, NDAs for DCV and ASV are under priority review by Japan’s Pharmaceutical and Medical Devices Agency for patients with chronic HCV genotype 1b, classified as either interferon-ineligible naïve/intolerant or non-responders to interferon and ribavirin.
