Torbjörn Bjerke, President and CEO, comments:
Orexo continued its strong development and we took further steps during the past quarter towards our goal of developing Orexo into a profitable pharmaceutical company. The most important events during the third quarter and until today were:

• Launch of Abstral® in Sweden and the start of sales.
• Approval of Abstral® for marketing in the UK. The decision was announced earlier than anticipated, and the launch of Abstral® in Europe’s largest market can now take place toward the end of the year.
• We are satisfied that the transfer of the rights to Rapinyl in North America took place earlier than planned. We and our partner ProStrakan will now conclude the Phase III studies, which are expected to be completed in December. At the same time, we are preparing the submission of the registration application and marketing of Rapinyl in North America.
