RATIONALE: Tissue plasminogen activator and captopril may help the body generate angiostatin. Angiostatin may stop the growth of cancer by stopping blood flow to the tumor. PURPOSE: This phase I/II trial is studying the side effects and best dose of tissue plasminogen activator and captopril and to see how well they work in treating patients with progressive metastatic cancer.

Study summary:

OBJECTIVES: Primary - Determine the maximum tolerated dose and toxicity of captopril and tissue plasminogen activator (tPA) in patients with progressive metastatic cancer. - Determine the in vivo generation of angiostatin by western analysis in patients treated with this regimen. Secondary - Determine the antitumor effect of this regimen in these patients. OUTLINE: This is a dose-escalation study. Patients receive tissue plasminogen activator (tPA) IV over 6 hours and oral captopril twice daily on days 1-5. Courses repeat every 14 days for up to 1 year in the absence of disease progression or unacceptable toxicity. Patients who achieve a complete response (CR) receive 2 additional courses beyond CR. Cohorts of 3-6 patients receive escalating doses of tPA and captopril until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 3 or 2 of 6 patients experience dose-limiting toxicity. PROJECTED ACCRUAL: Not specified.
