AstraZeneca and Bristol-Myers Squibb Announce Expansion of Worldwide Collaboration

AstraZenecaAstraZeneca and Bristol-Myers Squibb have announced expansion of their worldwide collaboration to include the development and commercialisation of dapagliflozin in Japan. Dapagliflozin, one of two investigational drugs under joint development by the companies, is currently being studied in Phase III clinical trials in several countries, including the U.S., to assess its efficacy and safety as a once-daily treatment for type 2 diabetes.

In January 2007, Bristol-Myers Squibb and AstraZeneca entered into a global collaboration, excluding Japan, to enable the companies to research, develop and commercialise dapagliflozin. The companies now have agreed to co-develop dapagliflozin in Japan with AstraZeneca having operational and cost responsibility for all development and regulatory activities on behalf of the collaboration. The two companies will jointly market the product in Japan, sharing all commercialisation expenses and activities and splitting profits/losses equally. Bristol-Myers Squibb will manufacture dapagliflozin and also book sales. Dapagliflozin is currently being studied in Phase II clinical trials in Japan.

"Bristol-Myers Squibb and AstraZeneca have been working together to develop dapagliflozin for type 2 diabetes for nearly two years - this inclusion of Japan was a natural progression of our collaboration and an important strategic step in our relationship," said Lamberto Andreotti, Executive Vice President and Chief Operating Officer, Bristol-Myers Squibb. "Our companies have a shared vision for these diabetes treatments, and this agreement will help ensure we can successfully launch and maximize the potential of dapagliflozin for the more than 6 million people in Japan living with type 2 diabetes."

"Last year, the cost of treating and preventing type 2 diabetes and its complications in Japan was more than USD 18.4 billion, which is a significant cost to Japanese society," said Bruno Angelici, Executive Vice President, International Sales and Marketing Organisation, AstraZeneca. "We have a long-standing presence in Japan, and our agreement with Bristol-Myers Squibb to bring a potentially important type 2 diabetes treatment to market in the region will not only help reduce this cost burden, but also reduce the impact this disease has on the country's health."

About Dapagliflozin
Dapagliflozin was specifically designed to be a novel, selective inhibitor of sodium glucose cotransporter 2 (SGLT2), which regulates the reabsorption of glucose in the kidney. It has a C-glucoside chemical structure, which prolongs the pharmacokinetic half-life and duration of action. Dapagliflozin is metabolized through the liver and excreted in the urine. Phase IIB data for Dapagliflozin were presented at the 2008 American Diabetes Association Annual Meeting and the 2008 European Association for the Study of Diabetes Annual Meeting.

About ONGLYZA™ (saxagliptin)
In addition to the companies collaboration on dapagliflozin, Bristol-Myers Squibb and AstraZeneca have been working together to develop another potential treatment for type 2 diabetes - ONGLYZA™ (saxagliptin) - globally, excluding Japan.

ONGLYZA, the proposed tradename for saxagliptin, is an investigational DPP-4 inhibitor being studied in clinical trials as a once-daily therapy to determine its efficacy and safety. Saxagliptin was specifically designed to be a selective inhibitor with extended binding to the DPP-4 enzyme, with dual routes of clearance. The companies submitted a New Drug Application to the U.S. Food & Drug Administration (FDA) on June 30, which has been officially filed by the FDA, and a Marketing Authorisation Application to the European Medicines Agency (EMEA) on July 1, which has been accepted for review by the Agency. The name ONGLYZA, if approved by the FDA and the EMEA, will serve as the trade name for saxagliptin.

Saxagliptin Phase III data have previously been presented as a monotherapy, as well as in combination with metformin, sulfonylureas and thiazolidinediones, commonly prescribed oral anti-diabetic medications. The overall clinical development program included over 5,000 individuals - more than 4,000 of whom were given saxagliptin. The worldwide collaboration for the development and commercialisation of saxagliptin will continue to exclude Japan. On December 27, 2006, Bristol-Myers Squibb and Otsuka Pharmaceutical Co., Ltd. announced an exclusive licensing agreement for saxagliptin in Japan.
