Antineoplaston Therapy in Treating Patients With Newly-diagnosed Glioblastoma Multiforme

Study Overview
=================
Brief Summary
-----------------
RATIONALE: Current therapies for Glioblastoma Multiforme provide very limited benefit to the patient. The anti-cancer properties of Antineoplaston therapy suggest that it may prove beneficial in the treatment of brain tumors. PURPOSE: This study is being performed to determine the effects (good and bad) that Antineoplaston therapy has on adults (≥ 18 years of age) with newly diagnosed Glioblastoma Multiforme.

Detailed Description
-----------------
OVERVIEW: This is a single arm, open-label study in which adults (≥ 18 years of age) with newly diagnosed Glioblastoma Multiforme 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 adults (≥ 18 years of age) with newly diagnosed Glioblastoma Multiforme, 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 adults (≥ 18 years of age) with newly diagnosed Glioblastoma Multiforme. 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.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Antineoplaston therapy<br>Antineoplaston therapy (Atengenal + Astugenal) by IV infusion every four hours for at least 12 months. Study subjects receive increasing dosages of Atengenal and Astugenal until the maximum tolerated dose is reached. | Drug: Antineoplaston therapy (Atengenal + Astugenal)<br>* Adults with a newly diagnosed Glioblastoma Multiforme 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.<br>* Other names: A10 (Atengenal); AS2-1 (Astugenal);|
