Phase II Studies in Patients With Metastatic Colorectal Carcinoma Previously Treated With Oxaliplatin (OXAL) or a Combination of Irinotecan (CPT-11) and Oxal


OBJECTIVES:

- Determine the tumor response rate in patients receiving irinotecan or fluorouracil and
leucovorin calcium for metastatic colorectal cancer previously treated with oxaliplatin
with or without irinotecan.

- Determine the time to tumor progression, time to treatment failure, and overall
survival of patients treated with these regimens.

- Determine the toxic effects of these regimens in these patients.

- Evaluate the quality of life of patients treated with these regimens.

OUTLINE: This is a multicenter study. Patients are stratified according to prior
chemotherapy (oxaliplatin-based therapy vs irinotecan and oxaliplatin combination therapy).
Patients are assigned to one of two treatment groups.

- Group I (prior oxaliplatin-based chemotherapy): Patients receive irinotecan IV over 90
minutes on day 1. Treatment repeats every 3 weeks.

- Group II (prior irinotecan and oxaliplatin combination chemotherapy): Patients receive
leucovorin calcium IV over 2 hours and fluorouracil IV continuously on days 1 and 2.
Treatment repeats every 2 weeks.

- Both groups: Treatment continues in the absence of disease progression or unacceptable
toxicity. Patients with a confirmed complete response for 2 consecutive courses may
discontinue treatment at investigator's discretion.

Quality of life is assessed at baseline, approximately every 6 weeks during treatment, and
then after the last course of treatment.

Patients are followed every 3 months for 5 years.

PROJECTED ACCRUAL: A total of 40-96 patients (20-48 per arm) will be accrued for this study
within 1-2 years.
