AstraZeneca PLC and MAP Pharmaceuticals, Inc. Announce Worldwide Collaboration to Develop and Commercialize Unit Dose Budesonide; AstraZeneca to Pay $40 Million in Cash Upfront; Deal Could be Worth Up to $900M

LONDON and MOUNTAIN VIEW, Calif., Dec. 19 /PRNewswire-FirstCall/ -- AstraZeneca (NYSE: AZN - News) and MAP Pharmaceuticals, Inc. (Nasdaq: MAPP - News) announced today an exclusive worldwide agreement to develop and commercialize Unit Dose Budesonide (UDB), MAP Pharmaceuticals’ proprietary nebulized formulation of budesonide. UDB is being developed by MAP Pharmaceuticals as a potential treatment for pediatric asthma and is currently in Phase III clinical development. UDB has the potential to be nebulized more quickly and at a lower nominal dose than the commercially available product.

Under the terms of the agreement, AstraZeneca will pay MAP Pharmaceuticals an upfront cash payment of $40 million and an additional $35 million upon the successful achievement of primary endpoint and safety results in the currently ongoing Phase III clinical study. In addition, upon the occurrence of certain events and conditions, MAP Pharmaceuticals is eligible to receive up to $240 million in other potential development and regulatory milestones. The agreement also provides for additional progressively demanding sales performance-related milestone payments of up to $585 million in the event the product is a considerable commercial success. This agreement is subject to review by the United States Government under the Hart-Scott-Rodino Act and becomes effective after the expiration or earlier termination of the waiting period (or any extension thereof).

AstraZeneca also will support and fund the establishment of a MAP Pharmaceuticals sales force to co-promote UDB in the United States for a certain period of time after product launch. MAP Pharmaceuticals is also eligible to receive significant double-digit royalty payments on net sales of UDB worldwide.

MAP Pharmaceuticals and AstraZeneca will develop UDB in the United States and AstraZeneca has rights to develop and commercialize UDB outside of the United States. Under the agreement, AstraZeneca will be responsible for future UDB development costs and AstraZeneca will reimburse MAP Pharmaceuticals for the costs of future UDB development activities with respect to United States registration incurred by MAP Pharmaceuticals.

David Brennan, Chief Executive Officer of AstraZeneca said, “MAP Pharmaceuticals’ advancement in Unit Dose Budesonide represents an important potential new option for treating children confronting asthma. AstraZeneca’s heritage in treating pediatric asthma, combined with MAP Pharmaceuticals’ expertise can open new areas of opportunity for both companies and has the potential to bring significant medical benefit to the wider community.”

“AstraZeneca is an ideal partner for UDB given their extensive expertise in developing and commercializing respiratory therapies, including for pediatric asthma,” said Timothy S. Nelson, President and Chief Executive Officer of MAP Pharmaceuticals. “We recognize AstraZeneca’s leadership position in this therapeutic area and their potential to help MAP Pharmaceuticals achieve its key objective of reaching the broadest set of children who suffer from asthma. This relationship represents an important step in the evolution of our company, as we leverage our partner’s significant expertise and resources to help us build a commercial infrastructure for subsequent product launches. In addition, this transaction greatly strengthens our balance sheet and provides us with additional financial resources moving forward.”

UDB is being developed utilizing a license to Elan’s proprietary NanoCrystal® Technology. The small size and stability of NanoCrystal® drug particles are designed to enable improved delivery efficiency of drug formulations to the lung via nebulization.

About UDB

UDB is being studied as a novel version of nebulized budesonide. Budesonide has been used clinically for more than 20 years. UDB is designed to be nebulized more quickly at a lower nominal dose than the commercially available product. MAP Pharmaceuticals has completed enrollment and randomized approximately 360 patients in a Phase 3 clinical trial to evaluate UDB for the potential treatment of pediatric asthma. The last patient in this trial is expected to complete the 12-week treatment period by the end of 2008. The safety data generated to date has shown UDB to be well tolerated with no significant adverse events.
