GALASHIELS, Scotland, June 27 /PRNewswire/ -- ProStrakan Group plc (LSE: PSK), the international specialty pharmaceutical company, announces that the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMEA) has issued a positive opinion recommending approval of Abstral (formerly branded as Rapinyl), the fast-acting tablet for breakthrough cancer pain. ProStrakan plans to launch Abstral in Sweden in Q3 2008 and, as a result of today's announcement, across Europe from the end of 2008.

Abstral is a fast-dissolving tablet for sub-lingual (under the tongue) administration of fentanyl intended for the management of breakthrough cancer pain in patients who are already receiving opioid analgesics. ProStrakan has in-licensed the exclusive rights to Rapinyl in Europe from the Swedish pharmaceutical company Orexo AB.

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.

Abstral was referred to the CHMP for review in September 2007 and has now gained a positive opinion recommending approval of the product. This will allow ProStrakan to obtain national licences throughout the EU, with launches following their receipt. ProStrakan has agreed, as a post-approval commitment, to supply the EMEA with final study reports and relevant analyses, when available, from the ongoing clinical programme currently being conducted in North America

In March 2008, Abstral received a Marketing Authorisation for Sweden, which was the Reference Member State (RMS) for the product during the decentralised procedure. As a result, Swedish clinicians will be the first in the world to be able to prescribe Abstral following its launch there, planned for Q3 2008, in a joint venture with Orexo AB.

Commenting on the positive opinion recommending approval of Abstral, Dr Wilson Totten, Chief Executive of ProStrakan, said:

"This is a very significant announcement for ProStrakan. Abstral will play a major role in the further development of our European business while, at the same time, providing clinicians with a patient-friendly formulation of fentanyl to prescribe to cancer patients suffering from breakthrough pain."
