Combination Chemotherapy and Cetuximab as First-Line Therapy in Treating Patients With Advanced and/or Metastatic Colorectal Cancer
A Two-arm Phase II Randomised Trial of Intermittent Chemotherapy Plus Continuous Cetuximab and of Intermittent Chemotherapy Plus Intermittent Cetuximab in First Line Treatment of Patients With K-ras-normal (Wild-type) Metastatic Colorectal Cancer
RATIONALE: Drugs used in chemotherapy work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Monoclonal antibodies, such as cetuximab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. It is not yet known whether giving combination chemotherapy together with intermittent cetuximab is more effective than combination chemotherapy given together with continuous cetuximab in treating colorectal cancer.
PURPOSE: This randomized phase II trial is studying giving combination chemotherapy together with intermittent cetuximab to see how well it works compared to combination chemotherapy given together with continuous cetuximab as first-line therapy in treating patients with advanced or metastatic colorectal cancer.

OBJECTIVES:
Primary
- To compare the activity, in terms of failure-free survival, of patients with K-ras-normal (wild type) advanced and/or metastatic colorectal cancer treated with intermittent combination chemotherapy comprising oxaliplatin, leucovorin calcium, and fluorouracil (OxMdG) or oxaliplatin and capecitabine (XELOX) and intermittent vs continuous cetuximab as first-line therapy.
- To compare the safety and feasibility of these regimens in these patients.
Secondary
- To compare the safety of cetuximab reintroduction, in terms of frequency of grade 3-4 allergic reactions in these patients.
- To compare improvement in disease control (i.e., complete response plus partial response plus stable disease) at 24 weeks in patients treated with these regimens.
- To compare overall and progression-free survival of patients treated with these regimens.
- To compare response rates at 12, 24, and 36 weeks in patients treated with these regimens.
- To compare toxicity of these regimens in these patients.
OUTLINE: This is a multicenter study. Patients are randomised to 1 of 2 treatment arms.
Arm I (intermittent chemotherapy and intermittent cetuximab): Patients receive 1 of the following combination chemotherapy and cetuximab regimens:
- OxMdG: Patients receive oxaliplatin IV over 2 hours and leucovorin calcium IV over 2 hours on day 1 and fluorouracil IV continuously over 46 hours on days 1 and 2. Patients also receive cetuximab IV over 1-2 hours on days 1 and 8. Treatment repeats every 14 days for up to 6 courses (12 weeks) in the absence of disease progression or unacceptable toxicity.
- XELOX (for patients with line-related problems): Patients receive oxaliplatin IV over 2 hours on day 1 and oral capecitabine twice daily on days 1-15 (28 doses). Patients also receive cetuximab IV over 1-2 hours on days 1, 8, and 15. Treatment repeats every 21 days for up to 4 courses (12 weeks) in the absence of disease progression or unacceptable toxicity.
After completion of 12 weeks of study therapy, patients with disease progression are removed from study. Patients with stable or responding disease stop treatment with OxMdG or XELOX and cetuximab and undergo clinical evaluation at least every 6 weeks until disease progression or clinical deterioration. Upon evidence of disease progression or clinical deterioration, patients restart treatment with OxMdG or XELOX and cetuximab as before and continue to alternate 12 weeks of treatment with treatment breaks in the absence of disease progression or unacceptable toxicity. Patients with disease progression during study therapy stop treatment and proceed to second-line therapy or best supportive care.
- Arm II (intermittent chemotherapy and continuous cetuximab): Patients receive OxMdG or XELOX and cetuximab for 12 weeks as in arm I. Patients with disease progression after 12 weeks of study therapy are removed from study. Patients with stable or responding disease* after 12 weeks of study therapy stop treatment with OxMdG or XELOX and continue treatment with cetuximab weekly as monotherapy in the absence of disease progression or unacceptable toxicity. Patients undergo clinical evaluation as in arm I. Upon progression, patients restart treatment with OxMdG or XELOX and continue cetuximab, as before, alternating 12 weeks of combined OxMdG or XELOX and cetuximab therapy with cetuximab monotherapy. Patients with disease progression during study therapy stop treatment and proceed to second-line therapy as in arm I.
Previously collected tumor tissue samples are obtained at baseline and analyzed by IHC for EGFR status of tumor.
After completion of study treatment, patients are followed every 12 weeks.
