ProStrakan Group to Establish US Sales Force through Strategic Alliance with NovaQuest

Galashiels, Scotland, 22 October, 2007 – ProStrakan Group plc (LSE: PSK), the international specialty pharmaceutical company, today announces the formation of a strategic alliance with NovaQuest, the strategic partnering group of Quintiles Transnational Corporation, to commercialise ProStrakan’s products in the United States of America.

Highlights of the collaboration include:

· An exclusive 75-person US sales force for ProStrakan, provided by NovaQuest, ahead of the US launch of Sancuso, ProStrakan’s medication targeted to prevent chemotherapy-induced nausea and vomiting

· NovaQuest will make up-front and milestone payments totalling US$10 million in cash over the first three years of the collaboration, to support the marketing and promotion of Sancuso, scheduled for launch in H2 2008

· NovaQuest has been granted warrants over 2.6 million new ordinary shares in ProStrakan at 75.5 pence per share (representing a 10% premium over the previous 30 days’ average share price) exercisable over 10 years

· ProStrakan will pay a tapering royalty on US Sancuso sales to NovaQuest over seven years

· Capacity for ProStrakan to market and promote further products in the US

ProStrakan and NovaQuest will work together to select the 75-person sales force from Innovex, the contract sales unit of Quintiles. These sales staff will promote products solely for ProStrakan and drive sales of Sancuso. NovaQuest will pay for the sales force for three years from launch; ProStrakan will then have the option to absorb the sales force into its own headcount. ProStrakan will pay an undisclosed tapering royalty on US Sancuso sales to NovaQuest over seven years.

The alliance is designed to establish ProStrakan’s US operation in preparation for the anticipated US approval of Sancuso and its launch, planned for the second half of 2008. It also leverages NovaQuest’s significant experience of launching US pharmaceutical brands and accelerating the business success of its partners.

Sancuso is a transdermal patch that delivers granisetron, an established 5-HT3 receptor antagonist, steadily into the bloodstream, preventing the side-effects of nausea and vomiting in patients undergoing chemotherapy, without the need for injection or having to swallow pills. ProStrakan announced the filing of the New Drug Application for Sancuso in the US in July this year.

ProStrakan has two further products currently undergoing US pivotal trials in pursuit of FDA approval. Fortigel (branded Tostran in most of Europe) is a 2% testosterone gel used as replacement therapy for male hypogonadism when testosterone deficiency has been confirmed by clinical symptoms and laboratory analyses. Cellegesic (branded Rectogesic in Europe) is a rectal ointment for the relief of pain associated with chronic anal fissures. Both products are already approved in Europe and ProStrakan plans to launch Fortigel and Cellegesic in the US in 2009.

ProStrakan already has an established sales presence in Europe – with operations in the UK, France, Germany, Spain, Italy, Benelux and Sweden – and has previously stated its strategic intention of building a US-based business.

Commenting on today’s announcement, Dr Wilson Totten, ProStrakan’s Chief Executive, said:

“The establishment of a US sales force is a transforming step forward for ProStrakan and is the realisation of a long-held ambition. Our own sales force, marketing our own product in the world’s largest market, will take ProStrakan onto a new level.

“The structure of this deal, in partnership with NovaQuest, effectively balances out the risk for ProStrakan and enables us to take this important step while retaining our ambition of reaching break-even during 2009.”

Patrick Jordan, Vice President of NovaQuest, said:

“Through this alliance, ProStrakan can avoid diminishing the value of its innovation excellence, as can often happen with traditional out-licensing arrangements. Nor will ProStrakan incur the significant expense of establishing its own US sales organisation. This alliance is an excellent example of NovaQuest’s ability to craft mutually beneficial solutions that enable our pharma partners to reach new heights of success.”

Sancuso Sancuso is a transdermal granisetron patch for the prevention of chemotherapy-induced nausea and vomiting. The NDA was filed successfully with the FDA on plan in June and the Group is currently awaiting confirmation of the acceptability of this filing. Subject to successful completion of the US approval process, the US launch of Sancuso is planned for H2 2008. The European MAA for Sancuso was lodged in July 2007.

Fortigel Branded as Tostran, Itnogen or Tostrex in the EU, Fortigel is a patented transdermal testosterone gel that utilises a proprietary metered dose delivery system for testosterone replacement therapy in male hypogonadism.

The metered dose delivery system permits dose adjustment to individual patient requirements. Hypogonadism is frequently characterised by reduced libido, loss of muscle mass, bone density and diminished energy levels. Estimates show that around one in 10 men over the age of 40 has clinically low testosterone.

Cellegesic Branded as Rectogesic in the EU, Cellegesic is a 0.4% topical nitroglycerin ointment for the treatment of pain associated with chronic anal fissures. It is estimated that, at any time, between 500,000 and 800,000 in Europe alone experience anal fissures.
