FDA ADVISORY COMMITTEE REQUESTS FURTHER
DATA ON ASTRAZENECA'S CASODEX(R) (BICALUTAMIDE)
150 MG FOR EARLY PROSTATE CANCER
AstraZeneca announced today that the Oncologic Drugs Advisory Committee (ODAC)
to the U.S. Food and Drug Administration (FDA) did not recommend approval of the
new indication for CASODEX 150 mg for the treatment of early stage prostate
cancer.
The panel recommendation does not impact on the current use and approval of
CASODEX 50 mg formulation, and also does not impact on CASODEX 150 mg
approvals in other countries.
Although the advisory committee could not reach a consensus on the
interpretation of the data and how the results from the trials apply
specifically to U.S. patients, the committee did agree that the data appears to
show CASODEX 150 mg is a viable treatment option for patients in other regions
of the world, such as Europe and Scandinavia. Despite the decision by the ODAC,
several panel members did agree that the CASODEX 150 mg data showed positive
benefits in the non-U.S. trials.
'While we are disappointed with the outcome of the ODAC meeting, we are
nevertheless encouraged by the positive comments from the panel in relation to
the data and the overall quality of the studies,' said Gerard T. Kennealey, MD,
Vice President, Oncology Research, AstraZeneca.
CASODEX 150 mg is already approved for the treatment of early stage disease in
more than 40 countries around the world, including the United Kingdom, Mexico,
Canada, Germany, Italy, and Australia, and AstraZeneca continues to seek
regulatory approvals in other markets.
The Supplemental New Drug Application (sNDA) is based on the
CASODEX Early Prostate Cancer (EPC) Trial Programme, the world's largest
prostate cancer treatment trial ever conducted with more than 8,000 patients in
23 countries. The programme consists of three prospective, randomised,
double-blind, placebo-controlled clinical trials and was designed on the same
premise as trials of tamoxifen in breast cancer. Adding tamoxifen to standard
treatment for early breast cancer, such as surgery, has been proven to reduce
the chance of the cancer returning and has saved thousands of women's lives.
In the EPC programme, approximately half the patients received CASODEX 150
mg/day and half received placebo, in addition to standard therapy of radical
prostatectomy, radiotherapy, or watchful waiting. Overall, CASODEX 150 mg
reduced the chance of disease progression or death in the absence of progression
by 42 per cent compared with placebo. In addition, CASODEX 150 mg significantly
reduced the risk of Prostate Specific Antigen (PSA) progression (defined as
doubling of PSA concentration, objective disease progression, or death). In
clinical practice, a rising PSA is frequently used as a biochemical marker for
progression of prostate cancer. In the EPC Program, CASODEX 150 mg was shown to
have a favourable tolerability profile, with the most frequently occurring side
effect being gynecomastia (breast enlargement; 68 per cent) and breast pain (73
per cent). Gynecomastia and breast pain were considered severe in only 6 per
cent and 5 per cent of patients, respectively. The overall incidence of other
side effects was similar for both treatment groups.
Even with the disappointing response from the ODAC, CASODEX continues to
contribute significant sales growth. 2002 sales through the first nine months
were $459M, 18 per cent above sales over the same period in 2001. The growth is
continuing to strengthen as additional countries approve CASODEX usage in early
prostate cancer. Additionally, usage of CASODEX 50 mg in advanced prostate
cancer in the USA and elsewhere remains strong.

research, development, manufacture and marketing of ethical

Background Information on Prostate Cancer
One in six men is at lifetime risk for being diagnosed with prostate cancer.
According to the American Cancer Society, nearly 190,000 new prostate cancer
cases will have been diagnosed in 2002, or about one new case every three
minutes. It is the most frequently diagnosed non-skin cancer and is the second
leading cause of cancer death among men after lung cancer.
