Burzynski Research Institute3 enrolled

Overview

Current therapies for Metastatic, Recurrent, or Refractory Neuroblastoma provide very limited benefit to the patient. The anti-cancer properties of Antineoplaston therapy suggest that it may prove beneficial in the treatment of Metastatic, Recurrent, or Refractory Neuroblastoma. PURPOSE: This study is being performed to determine the effects (good and bad) that Antineoplaston therapy has on patients with Metastatic, Recurrent, or Refractory Neuroblastoma.

Metastatic, Recurrent, or Refractory Neuroblastoma patients receive gradually escalating doses of intravenous Antineoplaston therapy (Atengenal + Astugenal) until the maximum tolerated dose is reached. Treatment continues up to12 months in the absence of disease progression or unacceptable toxicity. OBJECTIVES: * To determine the efficacy of Antineoplaston therapy in patients with Metastatic, Recurrent, or Refractory Neuroblastoma, as measured by an objective response to therapy (complete response, partial response or stable disease). * To determine the safety and tolerance of Antineoplaston therapy in patients with Metastatic, Recurrent, or Refractory Neuroblastoma. * To determine objective response, tumor size is measured utilizing MRI scans, which are performed every 8 weeks for the first two years, every 3 months for the third and fourth years, every 6 months for the 5th and sixth years, and annually thereafter.

Antineoplaston therapy (Atengenal + Astugenal)DRUG

Patients With Metastatic, Recurrent, or Refractory Neuroblastoma will receive Antineoplaston therapy (Atengenal + Astugenal). The daily doses of A10 and AS2-1 are divided into six infusions, which are given at 4-hourly intervals. Each infusion starts with infusion of A10 and is immediately followed by infusion of AS2-1.
