About

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die.

PURPOSE: Randomized phase II trial to compare the effectiveness of two different regimens of Ro 31-7453 in treating patients who have recurrent or refractory metastatic colorectal cancer.

Full description

OBJECTIVES:

• Compare the objective disease rate of patients with recurrent or refractory metastatic colorectal cancer treated with two dose schedules of Ro 31-7453.
• Compare the safety and tolerability of these regimens in these patients.
• Compare the response duration in patients treated with these regimens.
• Compare the time to progression and time to treatment failure in patients treated with these regimens.
• Determine the pharmacokinetic profiles of Ro 31-7453 and its major metabolites in these patients.
• Compare the overall survival of patients treated with these regimens.

OUTLINE: This is a randomized, open label, multicenter study. Patients are randomized to one of two treatment arms.

• Arm I: Patients receive oral Ro 31-7453 twice daily on days 1-4. Treatment repeats every 21 days in the absence of disease progression or unacceptable toxicity.
• Arm II: Patients receive oral Ro 31-7453 twice daily on days 1-14. Treatment repeats every 28 days in the absence of disease progression or unacceptable toxicity.

Patients are followed at 28 days and then every 3 months.

PROJECTED ACCRUAL: Approximately 160 patients (49 per treatment arm plus 61 additional patients in the arm determined to be most effective) will be accrued for this study within 1 year.

Sex: All

Ages: 18+ years old
