E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To assess whether:
• Expression of chemotherapy resistance marker ERCC-1 is associated with progression-free survival (PFS) in first-line metastatic colorectal cancer (CRC) patients treated with bevacizumab in combination with mFOLFOX6 or FOLFIRI
• Plasma level of vascular endothelial growth factor A (VEGF-A) as a potential biomarker for bevacizumab, and in combination with ERCC-1 expression as a chemotherapy regimen biomarker, is associated with different PFS |
|
E.2.2 | Secondary objectives of the trial |
To assess whether:
• High vs. low plasma VEGF-A is associated with overall survival (OS), objective response (OR), hepatic colorectal metastases resection (including R0 resection), or risk of specific toxicities
• High vs. low ERCC1 expression is associated with OS, OR, hepatic colorectal metastases resection (including R0 resection), or risk of specific toxicities
• Other potential biomarkers (including KRAS status) are associated with clinical outcomes
• mFOLFOX6 vs. FOLFIRI in combination with bevacizumab is associated with PFS within biomarker subgroups (e.g., ERCC1 [high vs. low] and pVEGF-A [high vs. low])
• Hepatic colorectal metastases resection rates (including R0 rates) differ between the two treatment arms. |

Total bilirubin < 1.5 x upper limit of normal (ULN) AND
Aspartate aminotransferase and alanine aminotransferase < 2.5 x ULN in patients without liver metastases or < 5 x ULN in patients with liver metastases
9. Adequate renal function:
Calculated creatinine clearance according to the formula of Cockroft and Gault >= 50 mL/min AND
Urine for proteinuria should be < 2 +. Patients discovered to have >= 2+ proteinuria on dipstick urinalysis at baseline should undergo a 24-hour urine collection and must demonstrate < 1 g of protein in 24 hours
10. International normalized ratio <= 1.5 and activated prothrombin time <= 1.5 x ULN for patients not receiving anti-coagulation therapy. The use of full-dose oral or parenteral anticoagulants is permitted as long as the INR or aPTT is within therapeutic limits (according to the medical standard of the enrolling institution) and the patient has been on a stable dose of anticoagulants for at least two weeks prior to the first study treatment
11. Patients with treated brain metastases are eligible for study participation. Patients may not receive ongoing treatment with steroids at screening. Anticonvulsants (at stable dose) are allowed. Treatment for brain metastases may be whole-brain radiotherapy, radiosurgery, neurosurgery, or a combination as deemed appropriate by the treating physician. Radiotherapy and stereotactic radiosurgery must be completed at least 28 days prior to randomization
12. Female patients should not be pregnant or breast-feeding. Female patients with childbearing potential should agree to use effective, non-hormonal means of contraception (intrauterine contraceptive device, barrier method of contraception in conjunction with spermicidal jelly or surgically sterile) during the study and for a period of at least 6 months following the last administration of study drugs. Female patients with an intact uterus (unless amenorrheic for the last 24 months) must have a negative serum pregnancy test within 7 days prior to randomization into the study
13. Male patients must agree to use effective contraception during the study and for a period of at least 6 months following the last administration of study drugs, even if they have been surgically sterilized. |

randomization, except for adequately treated carcinoma in situ of the cervix, basal or squamous cell skin cancer, localized prostate cancer treated surgically with curative intent, and ductal carcinoma in situ treated surgically with curative intent
