Study information

Scientific title

An assessment of imaging and circulating biomarkers in patients with metastatic colorectal carcinoma treated with the anti-vascular endothelial growth factor (anti-VEGF) antibody, bevacizumab



Study hypothesis

The purpose of the study is to identify biomarkers that can predict clinical benefit in patients treated with bevacizumab and chemotherapy for metastatic colorectal cancer. Our hypotheses are:
1. That a circulating biomarker at baseline or the percentage change in a parameter after single agent treatment will predict benefit in terms of progression-free survival (PFS)
2. That a circulating biomarker will correlate with stable disease or progression on maintenance therapy
3. That bevacizumab improves response rate and PFS in patients with recurrent colorectal cancer who have already been treated with induction and maintenance bevacizumab

Ethics approval

Central Manchester Ethics Committee approved on the 15th June 2009 (ref: 09/H1008/99)

Metastatic colorectal cancer


All patients will be treated initially with first line chemotherapy and bevacizumab. They will undergo imaging (dynamic contrast-enhanced magnetic resonance imaging [DCE MRI] and fluorothymidine positron emission tomography [FLT PET]), circulating (circulating endothelial cells, circulating angiomodulatory biomarkers, deoxyribonucleic acid [DNA] analysis) and tissue biomarker investigations.

The treatment will continue until disease progression at which point they will be randomised to receive second line chemotherapy with or without bevacizumab. The treatment will continue until further disease progression.

Phase II

Drug names


Primary outcome measures

To identify a biomarker or suite of biomarkers that predict clinical benefit in terms of PFS, in patients treated with bevacizumab for metastatic colorectal cancer.

Secondary outcome measures

1. To define biomarker(s) that detect progressive disease in patients treated with bevacizumab-containing regimens for metastatic colorectal cancer
2. To obtain preliminary data on the utility of biomarkers in patients who have been treated with cytotoxic chemotherapy and bevacizumab, followed by maintenance therapy who are then treated, at progression, with chemotherapy with or without bevacizumab

Target number of participants

70 (out of this, 25 will be entered into the FLT PET protocol)

Participant exclusion criteria

1. Surgery (including open biopsy) within 4 weeks prior to anticipated first dose of bevacizumab
2. Significant traumatic injury or radiotherapy during 4 weeks preceding potential first dose of bevacizumab
3. Adjuvant therapy within the previous 12 months
4. Patients with previous adjuvant exposure to oxaliplatin can only take part if it is more than 12 months since their last exposure to oxaliplatin and they have grade I or less, residual peripheral neuropathy
5. No previous exposure to VEGF inhibitors in the adjuvant setting
6. History or evidence upon physical examination of brain metastases. Evidence of spinal cord compression. Computed tomography (CT)/MRI of the brain is mandatory (within 4 weeks prior to randomisation) in case of clinical evidence of brain metastases.
7. Pregnant or breast-feeding women. Positive pregnancy test (serum or urine beta-human chorionic gonadotropin [ß-HCG]) for women of reproductive potential
8. Fertile woman of childbearing potential not using adequate contraception (oral contraceptives, intrauterine device or barrier method of contraception in conjunction with spermicidal jelly or surgically sterile)
9. Other malignancies within 5 years prior to randomisation, except for adequately treated carcinoma in situ of the cervix and/or basal cell skin cancer
10. Treatment with any other investigational agent, or participation in another clinical trial within 30 days prior to entering this trial
11. Known hypersensitivity to bevacizumab, 5-fluorouracil, capecitabine, oxaliplatin or irinotecan
12. Known dihydro-pyrimidine dehydrogenase deficiency
13. Non-healing wound, ulcer or bone fracture
14. Patients cannot enter the trial if they have developed a deep venous thrombosis (DVT) or commenced therapeutic anticoagulation for any other reason, e.g., atrial fibrillation (AF) within the 4 weeks preceding the trial. Patients with a known DVT or AF on stable therapeutic doses of low molecular weight heparin for greater than 4 weeks duration, can enter the trial.
15. Patients with haemorrhagic disorders
16. Poorly controlled hypertension (sustained blood pressure [BP] greater than 150/100 mmHg despite antihypertensive therapy
17. Previous cerebrovascular accident (CVA), transient ischaemic attack (TIA) or subarachnoid haemorrhage (SAH) within six months before trial entry
18. Clinically significant cardiovascular disease, for example:
18.1. Myocardial infarction or unstable angina within 6 months of trial entry
18.2. New York Heart Association (NYHA) grade 2 or worse congestive heart failure (CHF)
18.3. Poorly controlled cardiac arrhythmia despite medication
19. Current or recent (within 10 days prior to first dose of trial treatment) use of aspirin greater than or equal to 325 mg/day
20. Pre-existing sensory or motor neuropathy greater than or equal to grade 2, uncontrolled spinal cord compression, or
21. Carcinomatous meningitis or new evidence of brain or leptomeningeal disease
22. Predisposing colonic or small bowel disorders in which the symptoms are uncontrolled as indicated by baseline of greater than 3 loose stools daily
23. Prior history of chronic enteropathy, inflammatory enteropathy, chronic diarrhoea, unresolved bowel obstruction/sub-obstruction, extensive small intestine resection with chronic diarrhoea
24. History of anaphylaxis or known intolerance to atropine sulphate or loperamide or appropriate antiemetics to be administered in conjunction with chemotherapy
25. Patients with a colonic stent
26. Evidence of any other disease, metabolic dysfunction, physical examination finding or laboratory finding giving reasonable suspicion of a disease or condition that contra-indicates the use of an investigational drug or puts the patient at high risk for treatment-related complications
