The CEO’s comments on Q2 2013

"We streamlined operations and sharpened our focus”

The first half of 2013 was an eventful period and one in which we made important progress in a number of areas.

We streamlined the company’s operations and sharpened the focus on our proprietary prescription pharmaceuticals in the Nordic region by divesting Cross Pharma AB, the wholly-owned subsidiary engaged in parallel imports of pharmaceuticals. The sale of Cross Pharma AB to Unimedic AB further strengthens Medivir’s financial position.

Medivir’s key clinical phase product, simeprevir, has continued to develop according to plan and our partner, Janssen, has filed Marketing Authorisation Applications in three different regions of the world over the course of a two-month period. Simeprevir is now being evaluated by regulatory authorities for approval for the treatment of chronic hepatitis C in three major geographical territories, namely the USA, Europe and Japan and has, as a consequence, moved one step closer to the market. Additional efficacy and safety data were presented for simeprevir during the period. The results confirm that simeprevir, in combination with pegylated interferon and ribavirin, has a high level of efficacy and a good safety profile. In the USA, the FDA decided to grant simeprevir a "Priority Review”, which may shorten the time to market introduction of simeprevir. New interferon-free studies of simeprevir were initiated in partnership with Idenix, and other interferon-free studies proceeded according to plan.

Pharmaceutical sales developed according to plan during the quarter and posted an increase of SEK 1.7 million in comparison with the corresponding period in 2012 while retaining profitability. Mollipect, Citodon and Lithionit continued to be the biggest-selling products.

We recruited Henrik Krook as the new head of Commercial Operations. This recruitment brings in additional expertise and experience of Nordic markets other than Sweden, and this will be important for the establishment of a Nordic marketing organisation.

Medivir’s proprietary protease inhibitor projects against cathepsin K and cathepsin S developed well. The phase I trials with the cathepsin K inhibitor were concluded, and the data obtained from the phase Ib trials are now being analysed. The results will be presented at a scientific congress later this year. The cathepsin S project is currently evaluating a number of compounds and we are planning to select a candidate drug during the latter half of the year for further development and preparation for clinical trials.

In August we decided, within the framework of Medivir’s proprietary hepatitis C project, to focus our resources on the polymerase inhibitor programme as there is a clear need for nucleotide-based polymerase inhibitors. We also decided, at the same time, to discontinue our hepatitis C NS5A inhibitor programme as the competitive landscape includes numerous NS5A programmes with a similar profile.

President & CEO
