CEO’s comments: Improved operating result and higher royalty revenues During the period, we reached key goals in Orexo’s progress towards becoming a profitable pharmaceutical company. The operating result improved, due largely to higher license revenues. Royalty revenues from our Abstral and Edluar products totaled MSEK 5.5 during the third quarter, representing a threefold increase compared with the preceding quarter. Sales of Abstral recorded a robust trend in Europe. Edluar was launched in the US during the third quarter by our partner Meda. High growth in royalty revenues will be the key component in attaining sustainable profitability and we have every confidence in our products. Abstral has recently been launched in Spain and additional European launches are expected. In the US, the product will be launched during the second half of 2010, provided that the approval process progresses as planned. Licensing agreement with Novartis In August we signed a global licensing agreement for OX17 with Novartis. The licensing agreement will start to generate milestone payments in connection with the commencement of Phase III studies. Thereafter, Orexo will receive milestone payments upon major development achievements, and will be eligible for further milestone payments upon the attainment of certain sales targets. In addition, Orexo will receive considerable royalties on Novartis’ future sales of the product. We continue to have a great focus on business development in order to close additional revenue-generating partnerships with pharma partners. Lower operating expenses in 2010 Since Abstral and Edluar have been registered and launched, the costs related to those products will decrease significantly next year. During the quarter, we also completed the previously announced cost-cutting program. Overall, this leads us to forecast operating expenses for 2010 in the range of MSEK 200 to 220. Solid growth in revenues –combined with lower costs – indicate that we are increasingly approaching the stage at which we will become a pharmaceutical company with sustainable profitability.
