RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Gene therapy such as oblimersen may make tumor cells more sensitive to chemotherapy drugs. Combining irinotecan and oblimersen may kill more tumor cells.
PURPOSE: Phase I/II trial to study the effectiveness of combining oblimersen and irinotecan in treating patients who have metastatic or recurrent colorectal cancer.
|Condition or disease||Intervention/treatment||Phase|
|Colorectal Cancer||Biological: oblimersen sodium Drug: irinotecan hydrochloride||Phase 1 Phase 2|
OBJECTIVES: I. Determine the dose-limiting toxic effects and maximum tolerated dose of augmerosen (G3139) administered in combination with irinotecan in patients with unresectable metastatic or recurrent colorectal cancer. II. Determine the quantitative and qualitative toxicity of this drug combination in this patient population. III. Assess the plasma pharmacokinetics of this combination in these patients. IV. Document the antitumor activity of this drug combination in these patients in a phase II study. V. Determine the relevant biologic endpoints of treatment in tumor biopsies prior to and after therapy with G3139 at two dose levels and assess the pharmacokinetic and pharmacodynamic correlations.
OUTLINE: This is a dose-escalation, multicenter study. Patients receive augmerosen (G3139) IV continuously on days 1-7 and irinotecan IV over 90 minutes on day 6. Treatment continues every 21 days in the absence of unacceptable toxicity or disease progression. Cohorts of 3-6 patients receive escalating doses of G3139 and irinotecan until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 6 patients experience dose-limiting toxicity. Once the MTD is determined, additional patients are accrued to receive treatment with G3139 and irinotecan at the recommended phase II dose. Patients are followed every 30 days until toxicity resolves.
PROJECTED ACCRUAL: A maximum of 18 patients will be accrued for the phase I portion of this study. A maximum of 55 patients will be accrued for the phase II portion of this study.
