About

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 residual/recurrent/progressive Glioblastoma Multiforme.

Full description

OVERVIEW: This is a single arm, open-label study in which adults (≥ 18 years of age) with residual/recurrent/progressed 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 residual/recurrent/progressive Glioblastoma Multiforme following initial therapy, including radiotherapy, 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 residual/recurrent/progressive 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.

Enrollment: 40 patients
