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 trial to study the effectiveness of monoclonal antibody therapy in treating patients who have advanced solid tumors.

OBJECTIVES:

• Determine the maximum tolerated dose and recommended phase II dose of monoclonal antibody anti-anb3 integrin in patients with advanced solid tumors.
• Determine the toxic effects of this drug in these patients.
• Determine the pharmacokinetics and pharmacodynamics of this drug in these patients.
• Determine the potential anti-tumor activity of this drug in these patients.

OUTLINE: This is a dose-escalation study.

Patients receive monoclonal antibody anti-anb3 integrin IV over 30 minutes weekly. Courses repeat every 4 weeks in the absence of disease progression or unacceptable toxicity.

Cohorts of 3-6 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 6 patients experience dose-limiting toxicity. Once the MTD is determined, additional patients are treated as above at that dose level.

PROJECTED ACCRUAL: A total of 27-33 patients will be accrued for this study within 9-11 months.
