Purpose:

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 patients with anaplastic astrocytoma that has not responded to previous treatment.


Study summary:

OBJECTIVES: - Determine the safety and possible effectiveness of antineoplastons A10 and AS2-1 in patients with incurable anaplastic astrocytoma who experienced disease progression or recurrence or have residual disease after standard therapy. - Describe response, tolerance to, and side effects of this regimen in these patients. OUTLINE: Patients receive gradually escalating doses of antineoplaston A10 and antineoplaston AS2-1 by intravenous injection 6 times daily until the maximum tolerated dose is reached. Treatment continues for at least 3 months in the absence of toxicity and disease progression. Patients achieving complete response (CR) continue treatment for an additional 8 months after reaching CR. Tumors are measured every 2 months during the first year, every 3 months for the second year, every 3-4 months during the third and fourth years, every 4-6 months during the fifth year, and yearly thereafter. PROJECTED ACCRUAL: A total of 20-40 patients will be accrued for this study.
