Orexo's (STO:ORX) partner in Japan, Kyowa Hakko Kirin, has obtained positive phase III results in Japan for KW-2246, which is approved for the treatment of breakthrough pain in cancer patients and marketed under the brand AbstralTM in Europe. Kyowa Hakko Kirin will now proceed with preparations for a new-drug application for KW-2246 in Japan for use in continuous pain management of acute cancer pain (breakthrough pain).

Orexo announces that Kyowa Hakko Kirin, Orexo's partner in Japan, today confirms that it has obtained positive clinical phase III results for KW-2246 in Japan. The clinical study results revealed a statistically significant difference between KW-2246 and the placebo, and clinical effectiveness was confirmed. In addition, with regard to safety, no unacceptable side effects were found during the clinical study period.

Kyowa Hakko Kirin will now proceed with the preparations for a new-drug application for KW-2246 in Japan. According to the market research institute Datamonitor, the Japanese market for opioids is one of the largest markets in the world (Datamonitor 2008, Commercial and Pipeline Insight: Opioids).

Torbjörn Bjerke, President and CEO of Orexo, comments: "The positive phase III results in Japan are an important milestone for our successful collaboration with Kyowa Hakko Kirin. This marks another important step in the international development of AbstralTM and strengthening Orexo in the process of becoming a profitable pharmaceutical company".

Trial design

The clinical study was conducted using a crossover design involving a double-blind placebo-controlled trial, targeting patients to whom an opioid analgesic was administered at fixed intervals for intermediate to severe cancer pain and who use a morphine preparation for breakthrough pain, and a non-blind controlled trial with a morphine preparation.

About Abstral

Abstral is a fast-dissolving tablet for sub-lingual administration of fentanyl, intended for the management of breakthrough cancer pain in patients who are already receiving opioid analgesics.

Currently Abstral is sold in Sweden, UK and Germany and is ready for launch in France. In Sweden, Abstral is sold through Orexo's and ProStrakan's joint venture, ProStrakan AB. The product is being prepared for registration in Japan and in the US the clinical phase III is finalized.
