Study Arms:
- Beta-Glucan and Monoclonal Antibody 3F8 (Type: EXPERIMENTAL): This is a dose-escalation study of beta-glucan. Patients receive oral beta-glucan once daily on days -4 to 12 and monoclonal antibody 3F8 IV over 30-90 minutes on days 1-5 and 8-12. Treatment repeats every 4 weeks for up to 4 courses in the absence of disease progression or unacceptable toxicity and with a human antimouse antibody (HAMA) titer \< 1,000 U/mL.~Cohorts of 3-6 patients receive escalating doses of beta-glucan 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.~Patients undergo urine, bone marrow, and blood sample collection periodically for biological studies. Samples are analyzed for antibody-dependent cellular cytotoxicity, complement-mediated cytotoxicity, and serum HAMA response via immunohistochemistry.~After completion of study treatment, patients are followed periodica
