Trial Information

A Phase II Study of Oxaliplatin (OXAL), 5-Fluorouracil (5-FU), and Leucovorin (CF) in Patients With Metastatic Colorectal Carcinoma Previously Treated With Irinotecan (CPT-11)


I. Determine the tumor response rate in patients treated with oxaliplatin, fluorouracil, and
leucovorin calcium for metastatic colorectal cancer previously treated with irinotecan.

II. Determine the time to tumor progression, time to treatment failure, and overall survival
of patients treated with this regimen.

III. Determine the toxicity of this regimen in this patient population. IV. Assess the
quality of life of patients treated with this regimen.

OUTLINE: This is a multicenter study.

Patients receive oxaliplatin IV over 2 hours on days 1 and 15 and leucovorin calcium and
fluorouracil IV on days 1, 8, and 15. Treatment repeats every 28 days in the absence of
disease progression or unacceptable toxicity. Patients achieving a confirmed complete
response for 2 consecutive courses may discontinue study treatment at the investigators
discretion. Quality of life is assessed at baseline, approximately every 6-8 weeks during
treatment, and then after the last course of treatment. Patients are followed every 3 months
for 5 years.
