Janssen Submits New Drug Application to U.S. FDA for Simeprevir (TMC435) for Combination Treatment of Adult Patients with Genotype 1 Chronic Hepatitis C

RARITAN, N.J., March 28, 2013 /PRNewswire/ -- Janssen Research & Development, LLC (Janssen) today announced it has submitted a New Drug Application (NDA) to the U.S. Food and Drug Administration (FDA) seeking approval for simeprevir (TMC435), an investigational NS3/4A protease inhibitor, administered as a 150 mg capsule once daily with pegylated interferon and ribavirin for the treatment of genotype 1 chronic hepatitis C in adult patients.

"Hepatitis C is a complicated disease and genotype 1 hepatitis C can be particularly difficult to cure. Given the complexity and diversity of the patient population, physicians need multiple options to provide their patients a chance at treatment success," said Wim Parys , Global Head of Development, Infectious Diseases and Vaccines, Janssen. "The U.S. filing represents an important step forward in bringing simeprevir to market and in helping to battle this challenging disease."

Hepatitis C virus (HCV) is a blood-borne infectious disease of the liver that affects approximately 3.2 million people in the United States. When left untreated over time, HCV can cause significant damage to the liver, including cirrhosis.

The regulatory submission for simeprevir is supported in part by data from three pivotal Phase 3 studies: QUEST-1 and QUEST-2 in treatment-naïve patients and PROMISE in patients who have relapsed after prior interferon-based treatment. In each study, participants were treated with one 150 mg simeprevir capsule once daily for 12 weeks plus pegylated interferon and ribavirin for 24 or 48 weeks. Primary efficacy data from the Phase 3 studies will be presented at an upcoming medical meeting.

About Simeprevir
Simeprevir (TMC435) is an investigational NS3/4A protease inhibitor jointly developed by Janssen and Medivir AB for the treatment of genotype 1 chronic hepatitis C in adult patients with compensated liver disease. Simeprevir is believed to work by blocking the protease enzyme that enables the hepatitis C virus to survive and replicate in host cells.

About Hepatitis C
Hepatitis C, a blood-borne infectious disease of the liver and a leading cause of chronic liver disease, is the focus of a rapidly evolving treatment landscape. Approximately 150 million people are infected with hepatitis C worldwide - including approximately 3.2 million people in the United States - and 350,000 people per year die from the disease globally. When left untreated, HCV can cause significant damage to the liver including cirrhosis. Additionally, hepatitis C may increase the risk of developing complications from cirrhosis, which can include liver failure.
