A Multicenter, Open-Label, Randomized, Two-Arm Study of Irinotecan (CPT-11) Versus the Combination of Oxaliplatin + Irinotecan (CPT-11) as Second-Line Treatment of Metastatic Colorectal Carcinoma
A Multicenter, Open-Label, Randomized, Two-Arm Study of Irinotecan (CPT-11) Versus the Combination of Oxaliplatin + Irinotecan (CPT-11) as Second-Line Treatment of Metastatic Colorectal Carcinoma
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. It is not yet known if irinotecan is more effective with or without oxaliplatin in treating metastatic colorectal cancer.
PURPOSE: Randomized phase III trial to compare the effectiveness of irinotecan with or without oxaliplatin in treating patients who have metastatic colorectal cancer.
OBJECTIVES:
OUTLINE: This is a randomized, open label, multicenter study. Patients are stratified according to Karnofsky performance status (50-60% vs 70-100%), number of metastatic organs involved (1 vs 2 or more), lactic dehydrogenase (no greater than 1.5 times upper limit of normal (ULN) vs greater than 1.5 times ULN), and prior fluorouracil chemotherapy (adjuvant vs first-line treatment for metastatic disease). Patients are randomized to 1 of 2 treatment arms.
Courses repeat in each arm every 3 weeks for 1 year in the absence of disease progression or unacceptable toxicity.
Patients are followed at 30 days, every 4 weeks for 3 months, and then every 3 months thereafter.
PROJECTED ACCRUAL: A total of 596 patients (298 per arm) will be accrued for this study within 18 months.
