Janssen submits supplemental New Drug Application to U.S. FDA for OLYSIO™ for once-daily use in combination with Sofosbuvir for 12 weeks for the treatment of adult patients with genotype 1 chronic hepatitis C

Janssen Research & Development, LLC (Janssen) today announced it has submitted a Supplemental New Drug Application (sNDA) to the U.S. Food and Drug Administration (FDA) for simeprevir, an NS3/4A protease inhibitor marketed as OLYSIO™ in the United States, in combination with the nucleotide analog NS5B polymerase inhibitor sofosbuvir developed by Gilead Sciences, Inc. This regulatory submission is for the treatment of genotype 1 chronic hepatitis C (HCV) in adult treatment-naïve patients with advanced fibrosis and null responders with all stages of liver fibrosis.

OLYSIO™ is currently approved for the treatment of chronic hepatitis C infection as a component of a combination antiviral treatment regimen. OLYSIO™ efficacy has been established in combination with peginterferon alfa and ribavirin in HCV genotype 1-infected patients with compensated liver disease, including cirrhosis.

“Hepatitis C places a significant burden on the lives of those infected and if left untreated may cause significant damage to the liver, including cirrhosis and complications such as liver failure,” said Gaston Picchio, Hepatitis Disease Area Leader, Janssen Research & Development. “This filing brings us closer to potentially offering these patients a once-daily all-oral treatment combination that includes the direct-acting antiviral agents simeprevir and sofosbuvir.”

The regulatory submission for OLYSIO™ and sofosbuvir is supported by data from the Phase 2 COSMOS study which included treatment-naïve patients with advanced fibrosis (METAVIR F3 to F4 scores) and null-responder patients with all stages of liver fibrosis (METAVIR F0 to F4 scores).

In April 2014, Janssen announced initiation of the Phase 3 OPTIMIST trials examining the safety and efficacy of simeprevir and sofosbuvir without interferon or ribavirin for the treatment of chronic genotype 1 HCV infection.  In the first trial, known as OPTIMIST-1, the combination will be administered once daily for 8 or 12 weeks in chronic HCV genotype 1 infected patients without cirrhosis who are HCV treatment naive or treatment experienced.  In the second trial, known as OPTIMIST-2, the combination will be administered once daily for 12 weeks in HCV genotype 1 infected patients with cirrhosis who are HCV treatment naive or treatment experienced.   For more information please visit www.clinicaltrials.gov.
