Résumé
Date de début de l'étude : 1 février 1993
Date à laquelle le premier participant a commencé l'étude.OBJECTIVES: I. Determine the toxicity and maximum tolerated dose of iodine-131-labeled monoclonal antibody fragment ME1-14 F(ab')2 administered intracystically in patients with recurrent or newly diagnosed primary or metastatic malignant melanoma or other brain tumors. II. Identify any objective therapeutic responses to this treatment. OUTLINE: All patients receive a fixed dose of monoclonal antibody fragment ME1-14 F(ab')2 via an intralesional catheter; cohorts of 3-6 patients receive escalating doses of isotope conjugated to the antibody until the maximum tolerated dose is determined. Patients with newly diagnosed disease at entry may receive additional therapy with external-beam radiotherapy beginning 4 months after radioimmunotherapy (or sooner if disease progression occurs). Patients with recurrent disease at entry are followed without further therapy for at least 4 months after radioimmunotherapy; alternative therapy may be offered upon progression. All patients are followed at 4, 8, 16, and 24 weeks after treatment, then every 12 weeks for 1 year. PROJECTED ACCRUAL: Three to six patients will be entered at each dose studied.
