Scientific titleMulticentre international study of capecitabine ± bevacizumab as adjuvant treatment of colorectal cancer
Study acronymQUASAR 2
Study objectivesStudy hypothesis added as of 18/07/2007:
Treatment with a combination of capecitabine plus bevacizumab results in better disease-free survival (DFS) than treatment with capecitabine alone.

Please note that the trial title provided at time of registration was "QUASAR 2 Multicentre international study of capecitabine +/- bevacizumab as adjuvant treatment of colon cancer". The current trial title was added as of 02/07/2007.
Ethics approval(s)Metropolitan Multi-centre Research Ethics Committee, 03/09/2004, ref: 04/MRE11/18
Health condition(s) or problem(s) studiedColorectal cancer
InterventionRandomised to:
Arm A (standard arm)
Capecitabine 1250 mg/m^2, twice daily 12 hours apart (total daily dose 2500 mg/m^2) for 14 days (max 2500 mg twice a day [bd] [total daily dose 5000 mg]).
Treatment is repeated every 3 weeks for a total of eight cycles (24 weeks). One cycle = 3 weeks.

Arm B (experimental arm)
Capecitabine 1250 mg/m^2 twice daily, 12 hours apart (total daily dose 2500 mg/m^2) for 14 days (max 2500 mg twice daily [max total daily dose 5000 mg]).Treatment is repeated every 3 weeks for a total of eight cycles (24 weeks). One cycle = 3 weeks.
Bevacizumab 7.5 mg/kg will be administered initially over a 90 (±15) minute period on day 1. The infusion will be repeated every 3 weeks for a total of 16 cycles (48 weeks). One cycle = three weeks.

Key inclusion criteriaInclusion criteria amended as of 02/07/2007:
1. Histologically proven stage III (stage T2, T3 or T4) and stage II (any one or more of the following - stage T4, lymphatic invasion, vascular invasion, peritoneal involvement, poor differentiation) colorectal cancer (expected ratio 70% : 30%). N.B Patients can be Stage II, T3 as long as they have one of the other poor prognostic features. For the purposes of stratification, rectal cancers will be anything below the peritoneal reflection.
2. Patients must have undergone complete resection of the primary tumour without evidence of residual disease.
3. Patients must be randomised to start treatment a minimum of 28 days and maximum of 70 days* after surgery (If a subject has had a major surgical procedure, open biopsy, or significant traumatic injury within 28 days prior to study treatment start, or there is the anticipated need for major surgical procedure during the course of the study they are not eligible).
4. World Health Organization Performance Status 0 or 1.
5. Male or female outpatients age 18 years.
6. Written informed consent given.
7. Life expectancy of greater than or equal to 5 years, in terms of non-cancer-related morbidity.

*Calculation of these dates is based on date of surgery being day 1.

Inclusion criteria provided at time of registration:
1. Histologically proven stage III and high risk stage II (any of the following - stage T4, or lymphatic invasion, vascular invasion, peritoneal involvement) colon cancer (expected ratio 70%:30%)
2. Patients must have undergone complete resection of the primary tumour without evidence of residual disease
3. Patients must be randomised to start treatment a minimum of 28 days and maximum of 70 days after surgery. (If a subject has had a major surgical procedure, open biopsy, or significant traumatic injury within 28 days prior to study treatment start, or there is the anticipated need for major surgical procedure during the course of the study they are not eligible).
4. World Health Organisation (WHO) Performance Status 0 or 1
5. Male or female outpatients age ≥18 years
6. Written informed consent given
7. Life expectancy of ≥5 years
Key exclusion criteriaExclusion criteria amended as of 02/07/2007:
1. Previous chemotherapy, immunotherapy or infra-diaphragmatic radiotherapy.
2. Received any investigational drug or agent/procedure (i.e. participation in another treatment trial) within 4 weeks of randomisation.
3. Moderate or severe renal impairment (creatinine clearance <30 ml/min [calculated according to Cockroft-Gault formula]).
4. Any of the following laboratory values (tests must not have been carried out more than 2 weeks prior to randomisation):
a. Absolute Neutrophil Count (ANC) <1.5 x 109/L
b. Platelet count < 100 x 109/L
c. Total bilirubin > 1.5 Upper Limit of Normal (ULN)
d. Alanine Aminotransferase (ALT), Aspartate Aminotransferase (AST) > 2.5 x ULN
e. Alkaline phosphatase > 2.5 x ULN
5. Patients requiring chronic use of full dose oral or parenteral anticoagulants, high dose aspirin (>325 mg/day), anti-platelet drugs or known bleeding diathesis. Low dose aspirin is allowed.
