Monoclonal Antibody Therapy in Treating Patients With 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 Design:||Primary Purpose: Treatment|
|Official Title:||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|
|Study Start Date:||June 2001|
|Study Completion Date:||November 2004|
|Primary Completion Date:||November 2004 (Final data collection date for primary outcome measure)|
- 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.
