Clinical trial: Antineoplaston Therapy in Treating Patients With Metastatic, Recurrent, or Refractory Neuroblastoma

Summary: RATIONALE: Antineoplastons are naturally-occurring substances that may also be made in the laboratory. Antineoplastons may inhibit the growth of cancer cells.
  PURPOSE: This phase II trial studies the effectiveness of antineoplaston therapy in treating patients who have metastatic, recurrent, or refractory neuroblastoma.

Detailed description: OBJECTIVES:
  -  Determine the safety and possible effectiveness of antineoplastons A10 and AS2-1 in patients with metastatic, recurrent, or refractory neuroblastoma.
  -  Describe response, tolerance to, and side effects of this regimen in these patients.
  OUTLINE: This is an open-label study.
  Patients receive gradually escalating doses of antineoplaston A10 and antineoplaston AS2-1 by intravenous injection 6 times a day until the maximum tolerated dose is reached.
  Treatment continues for at least 2 months in the absence of unacceptable toxicity or disease progression. Patients achieving complete response (CR) continue treatment for an additional 8 months after reaching CR.
  Tumors are measured every 2 months for 1 year and then every 3 months for 1 year.
  PROJECTED ACCRUAL: Approximately 20-40 patients will be accrued for this study.
