AstraZeneca Receives Six Months Paediatric Exclusivity Patent Extension
For ARIMIDEX=AE From The FDA

29 November 2007

AstraZeneca today announced that the United States (US) Food and Drug
Administration (FDA) has granted an additional six month period of
exclusivity to market ARIMIDEX=AE (anastrozole) for its licensed breast
cancer indications until June 2010. Prior to paediatric exclusivity
being granted by the FDA, the patent was due to expire in December 2009.

ARIMIDEX is currently approved in the US for the for the following
indications:

* The adjuvant treatment of postmenopausal women with hormone receptor
positive early breast cancer (granted in 2002).
* The first-line treatment of postmenopausal women with hormone receptor
positive or hormone receptor unknown locally advanced or metastatic
breast cancer (granted in 2000).
* The treatment of advanced breast cancer in postmenopausal women with
disease progression following tamoxifen therapy (granted in 1995).

Dr John Patterson, Executive Director of Development at AstraZeneca said
=93Pre-clinical and clinical data supported the investigation of the
therapeutic potential of ARIMIDEX in paediatric conditions that manifest
symptoms resulting from increased oestrogen production, for example:
gynecomastia in pubertal boys and precocious puberty in girls with
McCune-Albright Syndrome (MAS). While pleased to have been able to work
with the FDA in investigating the potential benefits of ARIMIDEX in
these settings, AstraZeneca will not be seeking an indication in either
of these paediatric conditions based on trial results.=94
