Simeprevir has been approved in the USA as a new treatment for hepatitis C

Stockholm, Sweden — 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.
