  · OLYSIO™ (Simeprevir) provides a new triple therapy treatment option, as well
as the first ever 12-week interferon-free and ribavirin independent treatment
regimen, in combination with sofosbuvir, for appropriate patients in Europe

Stockholm, Sweden — Medivir AB (OMX: MVIR) today announces that simeprevir has
been granted marketing authorisation by the European Commission (EC) for the
treatment of adults with genotype 1 and 4 chronic hepatitis C in combination
with other medicinal products.

“The approval of simeprevir in Europe is a further step in our partner's global
strategy to enable an improved treatment for hepatitis C patients. This also
means that Medivir will now be able to offer this treatment to patients in the
Nordic region, where we have the marketing rights“, says Maris Hartmanis, CEO,
Medivir.

This marketing authorisation represents a significant milestone in the
development of new triple therapy hepatitis C (HCV) treatment options for
genotype 1 and 4 patients. It also includes simeprevir as part of an all oral 12
-week interferon-free direct-acting antiviral (DAA) regimen with or without
ribavirin (RBV), in genotype 1 or 4 patients, who are intolerant to or
ineligible for IFN treatment.

* Treatment-naïve and prior relapse patients with cirrhosis who are co-infected
with HIV should receive 48 weeks of treatment. Treatment with simeprevir must be
initiated in combination with PegIFN + RBV and administered for 12 weeks and
then followed by an additional 36 weeks of PegIFN + RBV.

The EC approval for simeprevir with PegIFN + RBV is based on a clinical trial
programme involving three pivotal phase III studies, with over 1000 patients.
The trials; QUEST-1, QUEST-2 and PROMISE, explored the use of simeprevir in
combination with PegIFN/RBV in treatment-naïve patients and patients who have
relapsed after prior interferon-base treatment. All three studies met their
primary endpoints and demonstrated that simeprevir in combination with
PegIFN/RBV, achieves significant cure rates when compared with PegIFN/RBV alone.

The EC approval for the combination of simeprevir and sofosbuvir also contains
the phase II study, COSMOS. This was based upon prior null responder and
treatment-naïve patients.
