At the end of the reporting period we had SEK 380 million in liquid assets and short term investments. The financial position and the stock listing represent significant strengths in the current business climate. Yesterday, an Extraordinary General Meeting of Diamyd Medical with overwhelming majority approved the sale of the U.S. subsidiary, Diamyd, Inc., including the development projects based on the Nerve Targeting Drug Delivery System (NTDDS) with applications in pain and neuropathy among others. The buyer, Periphagen Holdings, Inc. assumes all costs and revenues related to the NTDDS business from September 1, 2012, whilst Diamyd Medical retains the right to share in future successes of the NTDDS platform. The day before the Extra General Meeting, we announced the Board of Directors’ decision to limit the investment in further development of the diabetes vaccine Diamyd® for the treatment and prevention of autoimmune diabetes to SEK 30 million over the coming three years. A Swedish researcher initiated Phase II study is ongoing to evaluate whether Diamyd® can prevent or delay type 1 diabetes in children who are at high risk of developing the disease. Results from that study are scheduled for 2015. There are also plans from researchers to test Diamyd® in combination with other agents in small, less costly clinical pilot studies. The ambition is to have new scientific results within three years providing opportunities for partnering with major pharmaceutical companies or other funding. Through these two decisions we limit Diamyd Medical’s financial commitments towards the development projects where we have had set backs in clinical studies during the past 18 months. These measures should be seen as steps in Diamyd Medical's process to build a company generating a lasting robust return. Further information will be presented in connection with the Annual General Meeting to be held in December.
