A Phase IA Trial of Combined Murine IgG Monoclonal Anti-Transferrin Receptor Antibodies E2.3 and A27.15 in Cancer Patients
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 antibodies in treating patients who have advanced cancer.
OBJECTIVES: I. Determine the toxicities associated with a 4-hour infusion of antitransferrin receptor antibodies with one antibody administered by itself for 1 hour before the second antibody infusion is started. II. Determine the pharmacokinetics of monoclonal antibodies E2.3 and A27.15.
OUTLINE: This is a dose escalating study. Patients receive antitransferrin antibody A27.15 IV over 4 hours. One hour after the initiation of the A27.15 infusion, infusion of antibody E2-3 is added by IV piggy back. In the absence of antimouse antibodies and toxic effects, treatment continues once every 4 weeks in patients achieving minimal, partial, or complete remission. Treatment ceases in patients experiencing stable or progressive disease. In the absence of dose limiting toxicity in the first 3 patients treated, subsequent cohorts of 6 patients each receive escalating doses of antitransferrin antibodies E2.3 and A27.15 on the same dose schedule. If dose limiting toxicity occurs in 2 of 6 patients at a given dose level, then dose escalation ceases and the next lower dose is declared the MTD. Patients are followed for 3 weeks.
PROJECTED ACCRUAL: This study will accrue 18-27 patients within 2 years.
