Medivir: Simeprevir Has Been Approved in the USA as a New Treatment for Hepatitis C

Regulatory News:

Medivir AB (OMX: MVIR) today announced that U.S. Food and Drug Administration (FDA) has approved simeprevir for the treatment of chronic hepatitis C (CHC) genotype 1 infection, in combination with peginterferon alfa and ribavirin in adults with compensated liver disease, including cirrhosis, who are treatment-naïve or who have failed previous interferon therapy (pegylated or non-pegylated) with ribavirin.

"The USA approval is a large and important milestone in the global strategy that our partner Janssen has for simeprevir, to offer a new treatment option to many different hepatitis C patient groups,” said Maris Hartmanis CEO, Medivir.

The approval of simeprevir in the USA is based on several studies of patients with CHC genotype 1 infection. These studies include treatment-naïve patients (QUEST-1 and QUEST-2), and patients who have failed prior treatment with pegylated interferon and ribavirin; in PROMISE (prior relapsers) and ASPIRE (prior non-responders).

The USA approval triggers a milestone payment of €10m to Medivir.

Medivir is required under the Securities Markets Act to make the information in this press release public. The information was submitted for publication at 11.30 a.m. CET on 23 November 2013.

About Simeprevir

Simeprevir is an investigational NS3/4A protease inhibitor jointly developed by Janssen R&D Ireland and its affiliated companies and Medivir AB for the treatment of genotype 1 chronic hepatitis C in adult patients with compensated liver disease, including all stages of liver fibrosis.
