Erlotinib and Combination Chemotherapy in Treating Patients With Metastatic Colorectal Cancer

Colorectal Cancer Clinical Trial

Official title: A Phase I/II Study Of OSI-774 In Combination With Oxaliplatin, And 5-Fluourouracil In Patients With Metastatic Colorectal Carcinoma

Status Completed

Clinical Trial Summary

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Erlotinib may stop the growth of tumor cells by blocking the enzymes necessary for tumor cell growth. Combining erlotinib with combination chemotherapy may kill more tumor cells.

PURPOSE: Phase I/II trial to study the effectiveness of combining erlotinib with oxaliplatin, leucovorin, and fluorouracil in treating patients who have metastatic colorectal cancer.

Clinical Trial Description

OBJECTIVES:

• Determine the maximum tolerated dose of erlotinib when administered with oxaliplatin, leucovorin calcium, and fluorouracil in patients with metastatic colorectal cancer.

• Determine the pharmacokinetics of this regimen in these patients.

• Determine any antitumor activity of this regimen in these patients.

• Determine the time to progression in patients treated with this regimen.

• Determine the objective response rate and response duration in patients treated with this regimen.

• Determine the safety and tolerability of this regimen in these patients.

OUTLINE: This is a dose-escalation study of erlotinib.

• Phase I: During the first week of the first course only, patients receive oral erlotinib daily alone. Patients then begin the regular schedule comprising oral erlotinib daily, oxaliplatin IV over 2 hours on day 1, and leucovorin calcium IV over 2 hours and fluorouracil IV over 22 hours on days 1 and 2. Treatment repeats every 2 weeks for at least 6 courses in the absence of disease progression or unacceptable toxicity.

Cohorts of 3-6 patients receive escalating doses of erlotinib until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which at least 2 of 3 or 2 of 6 patients experience dose-limiting toxicity.

• Phase II: Patients receive erlotinib at the MTD plus oxaliplatin, leucovorin calcium, and fluorouracil as in phase I. Erlotinib may be administered alone if toxicity is caused by oxaliplatin, leucovorin calcium, and fluorouracil.

Patients are followed for at least 6 months or until disease progression.

PROJECTED ACCRUAL: A total of 4-18 patients will be accrued for phase I of this study within 1-4 months. A total of 50 patients will be accrued for phase II of this study within 10 months. ;
