Brief Summary
It has been found that the chemical changes that take place in a patient's body during the development of inflammation may provide an environment which stimulates cancer cells. One step in the development of inflammation is the production of certain chemical substances which are important in the formation and spread of tumours. These are called prostaglandins. Cyclo-oxygenase II (COX-2) is an enzyme (a substance that speeds up chemical changes in the body) involved in the production of these prostaglandins and although it is not usually present in most tissues it is made at the sites of inflammation. Celecoxib is a selective Non-Steroidal Anti Inflammatory Drug (NSAID) which works by blocking the action of the COX-2 enzyme, leading to a decrease in the production of prostaglandins and a reduction in inflammation. The purpose of this study is therefore to find out if celecoxib can be used after breast cancer treatment (chemotherapy and/ or radiotherapy) to reduce inflammation and thus reduce the ability of new tumours to grow and survive. 2590 women with primary breast cancer will be recruited in this study from several locations in the United Kingdom and Germany. Eligible patients will be randomly allocated a treatment group, which can be celecoxib or placebo. Both treatments are taken orally (celecoxib 400mg daily, placebo 2 tablets daily) for a total of 2 years. In addition, hormone receptor positive patients will receive endocrine treatment as per local practice. Patients will prematurely discontinue treatment with celecoxib/placebo if disease progression is confirmed or if patients experience unacceptable toxicity. Patients will be seen every 6 months for the first 3 years and then off treatment follow-up is carried out annually. Participating patients will also be given the option to take part in the pathology sub-study by donating a sample of the tumour tissue collected at the time of the primary surgery.

Outcome Measures
Primary Outcomes (1)
Disease Free Survival (DFS) Benefit of Two Years Adjuvant Therapy With the COX-2 Inhibitor Celecoxib Compared With Placebo in Primary Breast Cancer Patients.
From time of randomisation to the date of first event; with events contributing to the analysis defined as loco-regional and distant breast cancer recurrence, new primary breast cancer (ipsilateral or contralateral) and death without disease relapse (intercurrent death)
Patients will be followed up to 10 years. DFS will be calculated from date of randomization until the date of first documented DFS event, this will be assessed at 2 and 5 years
Secondary Outcomes (3)
Overall Survival
Date of randomisation until the date of death from any cause or censored at the date the patient was last seen alive, this will be assessed at 2 and 5 years
Number of Participants With Incidence of Second Primary Breast Cancers
From randomisation until a second primary breast cancer is diagnosed. Patients will be followed up to 10 years.
Cardiovascular Mortality
Patients are followed up to 10 years, any deaths within this timeframe with cardiovascular involvement reported are included in the analysis.
Study Arms (2)
Celecoxib
EXPERIMENTALPatients in this arm will receive 400mg of celecoxib once daily. In addition, Hormone Receptor (+) patients will receive endocrine treatment according to local practice.
Placebo
PLACEBO COMPARATORPatients in this arm will receive 2 tablets once daily. In addition Hormone Receptor (+) patients will receive endocrine treatment according to local practice.
Interventions
Patients will receive 400mg of Celecoxib once daily for two years or until disease progression (if before the two years limit) or until development of unacceptable toxicities. In addition ER(+) patients will receive endocrine treatment according to local practice.
