Brief summary
RATIONALE: Mistletoe lectin may slow the growth of cancer cells and be an effective treatment for solid tumors. PURPOSE: Phase I trial to study the effectiveness of mistletoe lectin in treating patients who have advanced solid tumors that have not responded to previous therapy.
Detailed description
OBJECTIVES: * Determine the maximum tolerated dose and dose-limiting toxicity of mistletoe lectin (recombinant viscumin) in patients with advanced solid tumors who have failed standard therapy. * Determine the pharmacokinetics of this regimen in these patients. * Determine whether induction of antibodies against recombinant viscumin occurs in these patients. * Determine whether immunological stimulation at the RNA level of immune cells occurs in patients treated with this regimen. * Determine whether modification of endothelial parameters occurs in patients treated with this regimen. * Determine the objective response rates in patients treated with this regimen. OUTLINE: This is a dose-escalation study. Patients receive mistletoe lectin (recombinant viscumin) IV over 1 hour twice weekly. Courses repeat every 3 weeks in the absence of disease progression or unacceptable toxicity. Cohorts of 1-3 patients receive escalating doses of recombinant viscumin until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose at which 20% of patients experience dose-limiting toxicity during the first course. Additional patients are treated at the MTD. Patients are followed every 3 months until disease progression or initiation of another therapy. PROJECTED ACCRUAL: A minimum of 37 patients will be accrued for this study.
