York Heart Association (NYHA) grade II or greater congestive heart failure, serious cardiac arrhythmia
requiring medication; or uncontrolled hypertension].
(9) Concomitant treatment with sorivudine or its chemically related analogues such as brivudine.
(10) Pregnant (positive pregnancy test within 7 days of starting treatment), or lactating women.
(11) Sexually active patients of child bearing potential not using adequate contraception (male and female).
(12) Previous malignancies other than adequately treated in situ carcinoma of the uterine cervix or basal or
squamous cell carcinoma of the skin, unless there has been a disease-free interval of at least 10 years.
(13) Lack of physical integrity of the upper gastrointestinal tract, malabsorption syndrome or inability to take oral
medication.
(14) Chronic inflammatory bowel disease and/or bowel obstruction and/or active peptic ulcer.
(15) History of uncontrolled seizures, central nervous system disorders or psychiatric disability judged by the
investigator to be clinically significant precluding informed consent or interfering with compliance for oral drug
intake.
(16) Patients with known allergy to Chinese hamster ovary cell proteins or other recombinant human or
humanized antibodies or to any excipients of bevacizumab formulation; or to any other study drugs.

Summary
Brief summary
This study looks at the effects of the drug capecitabine with or without bevacizumab in the treatment of patients with stage III colorectal cancer. You can join this study if you have cancer of the back passage (rectum) or large bowel (colon). Trial details: Participants will be divided into two groups. One group will receive oral capecitabine (from day 1 to day 14, rest for 7 days then repeat every 3 weekly for a total of 8 cycles), plus intravenous(IV) bevacizumab (one dose on day 1, repeated every 3 weekly for 16 cycles). The other group will receive capecitabine alone (from day 1 to day 14, rest for 7 days then repeat every 3 weekly for a total of 8 cycles), which is standard treatment. New preventative chemotherapies have been developed to reduce the risk of relapse of colorectal cancer. QUASAR2 uses a new combination of an oral chemotherapy drug (capecitabine) and a molecularly targeted therapy (bevacizumab), to determine whether this is more effective and less toxic than capecitabine alone. Colorectal cancer is the most commonly occurring cancer in Australia (excluding non-melanomic skin cancer), and the second most common cancer-related cause of death, responsible for 4,447 deaths in 2003 (1) As many as 40% of patients who undergo potentially curative treatment will ultimately relapse and die of metastatic disease. This observation has led to the development of adjuvant chemotherapies which reduce the risk of relapse. QUASAR2 uses a new combination for adjuvant therapy: an oral chemotherapy drug (capecitabine) and a molecularly targeted therapy (bevacizumab), to define whether this is superior in efficacy and less in toxicity than capecitabine alone, which is a standard of care in this disease.
