Antineoplaston Therapy in Treating Children With Rhabdoid Tumor of the Central Nervous System

Phase II Study of Antineoplastons A10 and AS2-1 in Children With Rhabdoid Tumor of the Central Nervous System

RATIONALE: Current therapies for childhood Rhabdoid tumors provide limited benefit to the patient. The anti-cancer properties of Antineoplaston therapy suggest that it may prove beneficial in the treatment of childhood Rhabdoid tumors.

PURPOSE: This study is being performed to determine the effects (good and bad) that Antineoplaston therapy has on children (> 6 months of age) with Rhabdoid tumors.

Study Overview

• Status: Terminated
• Conditions: Rhabdoid Neoplasm of CNS
• Intervention / Treatment: Drug: Antineoplaston therapy (Atengenal + Astugenal)

Detailed Description

OVERVIEW: This is a single arm, open-label study in which children with Rhabdoid tumors receive gradually escalating doses of intravenous Antineoplaston therapy (Atengenal + Astugenal) until the maximum tolerated dose is reached. Treatment continues for at least 12 months in the absence of disease progression or unacceptable toxicity.

OBJECTIVES:

• To determine the efficacy of Antineoplaston therapy in children with a Rhabdoid tumor, 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 children with a Rhabdoid tumor.
• 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.

PROJECTED ACCRUAL: A total of 20-40 patients will be accrued to this study.
