Monoclonal Antibody Therapy in Treating Patients With Advanced Colorectal Cancer

Phase I/II Study of MEDI-522, A Humanized Monoclonal Antibody Directed Against the Human Alpha V Beta 3 Integrin, in Patients With Irinotecan-Refractory Advanced Colorectal Cancer

RATIONALE: Monoclonal antibodies can locate tumor cells and either kill them or deliver tumor-killing substances to them without harming normal cells.

PURPOSE: Phase I/II trial to study the effectiveness of monoclonal antibody therapy in treating patients who have advanced colorectal cancer that has not responded to irinotecan.

Study Overview

• Status: Completed
• Conditions: Colorectal Cancer
• Intervention / Treatment: Biological: etaracizumab

Detailed Description

OBJECTIVES:

• Determine the recommended phase II dose of monoclonal antibody anti-anb3 integrin in patients with irinotecan-refractory advanced colorectal cancer.
• Determine the safety and tolerance of this drug in these patients.
• Determine any antitumor activity of this drug in these patients.
• Determine the objective response rate, response duration, and time to progression in patients treated with this drug.
• Determine the pharmacokinetics of this drug in these patients.

OUTLINE: This is a dose-escalation study.

Patients receive monoclonal antibody anti-anb3 integrin IV over 30 minutes once weekly on weeks 1-52 in the absence of disease progression or unacceptable toxicity. Patients with responding disease may continue therapy.

Cohort of 4-6 patients receive escalating doses of monoclonal antibody anti-anb3 integrin until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 4 or 6 patients experience dose-limiting toxicity. Once the MTD is determined, additional patients are treated at that dose in the phase II portion of the study.

Patients are followed every 3 months for 2 years.

PROJECTED ACCRUAL: A total of 4-24 patients will be accrued for phase I of this study and a total of 40 patients will be accrued for phase II of this study.
