Clinical Trial 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 is studying how well antineoplaston therapy works in treating children with rhabdoid tumor of the central nervous system.

Description:

OBJECTIVES:

• Demonstrate the antitumor activity of antineoplastons A10 and AS2-1 in children with rhabdoid tumor of the central nervous system by determining the proportion of patients who experience an objective tumor response.

• Evaluate the adverse effects of and tolerance to this regimen in these patients.

OUTLINE: This is an open-label study.

Patients receive gradually escalating doses of intravenous antineoplaston A10 and antineoplaston AS2-1 6 times per day until the maximum tolerated dose is reached. Treatment continues for at least 2 months in the absence of disease progression or unacceptable toxicity. After 2 months, patients with responding or stable disease may continue treatment.

Tumors are measured every 8 weeks for 2 years, every 3 months for the third and fourth years, every 6 months for the fifth and sixth years, and then annually thereafter.

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