Alternate Title

Monoclonal Antibody Therapy in Treating Patients With Leptomeningeal Cancer

Basic Trial Information

Objectives

1. Define the clinical toxicities of intrathecal iodine I 131 monoclonal antibody 3F8 (I-3F8) in patients with GD2 positive leptomeningeal neoplasms.
2. Determine whether I-3F8 can detect GD2 positive leptomeningeal tumors.
3. Measure the cerebrospinal fluid (CSF) levels and serum pharmacokinetics of I-3F8 in these patients.

Entry Criteria

Disease Characteristics:

• Histologically confirmed malignancy expressing GD2, including, but not limited to:
  • Medulloblastoma/primitive neuroectodermal tumor of the CNS
  • Malignant glioma
  • Neuroblastoma
  • Retinoblastoma
  • Ependymoma
  • Sarcoma
  • Melanoma
  • Small cell lung carcinoma
  • Other tumor types must have GD2 expression confirmed by immunohistochemical staining

• Cerebrospinal fluid or leptomeningeal disease that is refractory to conventional therapy or for which no conventional therapy exists

• Prior measurable human anti-mouse monoclonal antibody titer allowed

Prior/Concurrent Therapy:

Biologic therapy:

• Prior monoclonal antibody treatment allowed

Chemotherapy:

• Prior chemotherapy allowed
• Must have recovered from all hematopoietic and neurologic side effects of prior chemotherapy

Endocrine therapy:

• Not specified

Radiotherapy:

• Prior radiotherapy allowed
• At least 6 weeks since prior cranial or spinal irradiation

Surgery:

• Not specified

Patient Characteristics:

Age:

• 3 and over

Performance status:

• Not specified

Life expectancy:

• At least 2 months

Hematopoietic:

• Absolute neutrophil count greater than 1,000/mm³
• Platelet count greater than 50,000/mm³

Hepatic:

• Bilirubin less than 3 mg/dL

Renal:

• Creatinine less than 2 mg/dL
• Blood urea nitrogen less than 30 mg/dL

Other:

• May have active malignancy outside the central nervous system
• No obstructive hydrocephalus
• No CNS grade 3 or 4 toxicity as a consequence of prior treatments
• No life threatening infection

Expected Enrollment

Approximately 3-30 patients will be accrued for this study over 2-3 years.

Outline

This is a dose escalation study.

Patients receive a single injection of intraventricular or intrathecal iodine I 131 monoclonal antibody 3F8. Patients without objective disease progression and no grade 3 or 4 toxicity 6 weeks after the first dose may receive a second injection.

Cohorts of at least 3 patients are entered at escalating doses of I-3F8. If grade 3 or worse toxicity occurs in 1 or more of 3 patients at a given dose level, then 3 additional patients are accrued at that level. If 2 or more of 6 patients at a given dose level experience grade 3 or worse toxicity, then that dose is declared the maximum tolerated dose (MTD).

Patients are followed weekly for 4 weeks.
