Résumé
Date de début de l'étude : 1 avril 1998
Date à laquelle le premier participant a commencé l'étude.OBJECTIVES: I. Determine the maximum tolerated dose and dose limiting toxicity of yttrium Y 90-labeled humanized anti-CD22 monoclonal antibody LL2(90Y-hLL2 IgG) in patients with B-cell malignancies. II. Determine the pharmacokinetics and biodistribution of indium In 111 humanized LL2 (111In-hLL2 IgG) in these patients. III. Evaluate the immunogenicity of repeated injections of 90Y-hLL2 IgG in these patients. IV. Determine whether 90Y-hLL2 IgG versus indium In 131 humanized LL2 IgG has a therapeutic advantage based on organ and tumor dosimetry obtained with 111In-hLL2 IgG. OUTLINE: This is a dose escalation study. Patients are stratified into risk groups (high vs low). Patients receive pretherapy imaging with indium In 111 humanized LL2 IgG IV for up to 30 minutes on days -7 to 0. Patients receive yttrium Y 90-labeled humanized anti-CD22 monoclonal antibody LL2 (90Y-hLL2-IgG) IV for up to 30 minutes on day 0. Cohorts of 3-6 patients receive escalating doses of 90Y-hLL2-IgG until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding the dose at which 2 of 3 or 2 of 6 patients experience dose limiting toxicity. Patients are followed every 2 weeks for 1 month, monthly for 2 months, and then every 6 months thereafter. PROJECTED ACCRUAL: A total of 18-24 patients will be accrued for this study within 1-2 years.
