Orexo’s AbstralTM receives two further large EU market approvals in France and Spain

Orexo (NASDAQ-OMX:ORX), announces that AbstralTM has received Marketing Authorisation from the French and Spanish regulatory authorities for the treatment of breakthrough cancer pain.

AbstralTM is expected to be launched during the second half of 2009 in France and Spain, following pricing and reimbursement negotiations with the relevant authorities, by ProStrakan (LSE:PSK), Orexo’s exclusive licensing partner for AbstralTM in Europe and North America. The two new approvals mean that AbstralTM has been approved in five European markets including Sweden, the UK and Germany since March of 2008, with further approvals anticipated in 2009. The approvals in France and Spain trigger milestone payments of EUR 1.3 million to Orexo.

Commenting on the news, Torbjörn Bjerke, President and CEO of Orexo, said “AbstralTM is a very important product for helping cancer patients manage their pain and with this approval patients across the majority of the European market can now benefit from the product. The royalty stream that this product will generate will bring us closer to our goal of becoming a sustainable, profitable pharmaceutical company. ProStrakan is doing an excellent job of rolling out AbstralTM to the major European markets, and together we are anticipating to be in a position to file for USA approval for the product in 2009. We look forward to continuing our successful partnership with ProStrakan in Europe and North America in the near future.”

AbstralTM is a sublingual (under the tongue) tablet for the fast administration of fentanyl, an opioid commonly used to treat breakthrough cancer pain in patients who are already receiving opioid analgesics. AbstralTM’s formulation is based on Orexo’s unique sublingual tablet technology in which a rapidly dissolving tablet is placed under the tongue and the active substance is absorbed by the mucous membrane, resulting in very rapid pain relief for patients suffering from breakthrough pain.

AbstralTM received a positive recommendation for approval in Europe by the EMEA’s Committee for Medicinal Products for Human Use in June 2008. It is currently launched in
reference country Sweden, the UK and Germany.

ProStrakan is Orexo’s exclusive licensing and distribution partner for AbstralTM in Europe and North America. Orexo also recently signed a licensing and distribution agreement for AbstralTM with NovaMed for China and with Neopharm for Israel. Orexo already has other partnership agreements for AbstralTM in Eastern Europe and the CIS with Gedeon Richter, in Japan with Kyowa Hakko Kirin and for the other territories in Southeast Asia with Hospira.

Breakthrough cancer pain
It is estimated that there are in excess of five million people with cancer in Europe (1), that 30% of these suffer pain as a result(2) and that 65% of these have breakthrough cancer pain(3).

Breakthrough cancer pain is a brief and often severe flare of pain experienced by patients suffering from cancer that occurs even though a person may be taking pain relief medicine regularly for their persistent pain. It is known as breakthrough pain because it is pain that "breaks through" a regular pain medicine schedule. It may be caused by the cancer itself or it may be related to cancer treatment. For some people, breakthrough pain occurs during certain everyday activities, such as walking or dressing. For others, it occurs unexpectedly without any apparent cause.
