About

RATIONALE: Biological therapies such as beta-glucan use different ways to stimulate the immune system and stop cancer cells from growing. Monoclonal antibodies can locate tumor cells and either kill them or deliver tumor-killing substances to them without harming normal cells. Combining beta-glucan and monoclonal antibody may kill more tumor cells.

PURPOSE: Phase I trial to study the effectiveness of combining beta-glucan and monoclonal antibody in treating patients who have metastatic neuroblastoma.

Full description

OBJECTIVES:

• Determine the maximum tolerated dose of beta-glucan and monoclonal antibody 3F8 in patients with metastatic neuroblastoma.
• Determine the toxicity of this regimen in these patients.
• Assess the biological effects of this regimen in these patients.

OUTLINE: This is a dose-escalation study.

Patients receive oral beta-glucan and monoclonal antibody 3F8 (MOAB 3F8) IV within 1.5 hours on days 1-5 and 8-12. Treatment repeats every 28 days for up to 4 courses in the absence of disease progression or unacceptable toxicity.

Cohorts of 6 patients receive escalating doses of beta-glucan and MOAB 3F8 until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which at least 2 of 6 patients experience dose-limiting toxicity.

Patients are followed monthly for 6 months, every 2 months for 6 months, and then every 3-6 months for 2 years.

PROJECTED ACCRUAL: A maximum of 24 patients will be accrued for this study within 2 years.

Sex: All

Ages: Under 49 years old

Volunteers: No Healthy Volunteers
