The CEO’s comments on Q1 2014

Market uptake for Simeprevir was very good and Medivir received SEK 162 million
in royalties for the quarter
The year started well and one of the most important events during the quarter
was the approval of simeprevir by the Russian Ministry of Health. Russia has the
world’s third highest prevalence of hepatitis C, according to the World Health
Organization (WHO), with approximately 3.7 million people infected. In January
alone, 4,858 new cases of hepatitis C were diagnosed in Russia and there is a
substantial need for a safe and effective treatment alternative like simeprevir.

We were also delighted when the European Medicines Agency’s advisory committee,
the Committee for Medicinal Products for Human Use (CHMP), recommended Marketing
Authorisation in the EU for the use of simeprevir in combination with other
antiviral medicinal products. The recommendation applies to the treatment of
chronic hepatitis C in adult patients. We anticipate receiving European approval
before the summer in what will be the next important step forward for Medivir,
in that the company holds the sales rights for the Nordic market. The sales
development in the markets in which simeprevir has already been launched by our
partner, Janssen – Japan, the USA and Canada – was strong during the first
quarter of the year. Royalties from Janssen’s global sales during the first
quarter totalled SEK 161.7 million, demonstrating very good market uptake.

The development of a completely interferon- and ribavirin-free treatment is one
of the important goals for the future in the hepatitis C area. Our partner,
Janssen, is currently conducting a number of studies, both internally and in
partnership with other companies, in order to achieve this goal. Two new phase
III studies were recently initiated: the first is OPTIMIST, which entails an
interferon- and ribavirin-free combination treatment with simeprevir and
sofosbuvir over an eight- or twelve-week period. Janssen also presented positive
and unique results from the phase II COSMOS study at the EASL conference. Strong
data on European patients, based on subgroup analyses from the earlier phase III
studies, and final efficacy data for patients infected with genotype 4 HCV, were
also presented.

Our own in-house research projects are proceeding according to plan towards
their goals for 2014. Our strategic work has a strong focus on the growing
requirement to ensure, at an early stage in the research process, that we can
demonstrate both the medicinal benefits and cost-effectiveness of a potential
new pharmaceutical product in comparison with existing treatments.

Our pharmaceutical portfolio comprises 16 prescription pharmaceuticals that are
marketed in the Nordic region. Our own pharmaceutical sales experienced a slight
downturn during the first quarter, primarily due to fewer unit sales for
Mollipect as a result of a weak influenza and common cold season. The
pharmaceutical portfolio as a whole generated a turnover of SEK 46.4 million.
April saw the market relaunch of Suscard – an established pharmaceutical for the
treatment of angina pectoris.

We have a strong focus on specialist pharmaceuticals in the growth phase. Our
innovation and launch competence in the specialist care sector are both
important components of our endeavours to generate sustainable profitability.
One step towards this goal was taken in April with the Nordic market launch of
Adasuve – a new specialist pharmaceutical for the treatment of agitation
associated with bipolar disorder and schizophrenia.

Medivir has strengthened the company’s marketing and sales organisation during
the quarter, and the organisation, which now has a presence in Norway, Denmark
and Finland, as well as Sweden, has been working intensively on the product
launch of Adasuve. The organisation is also well-prepared for the launch of
simeprevir in the Nordic region, which we expect to take place towards the end
of the second quarter.
