RATIONALE: Current therapies for adult recurrent/progressive oligodendrogliomas provide very limited benefit to the patient. The anti-cancer properties of Antineoplaston therapy suggest that it may prove beneficial in the treatment of childhood brain tumors.
PURPOSE: This study is being performed to determine the effects (good and bad) that Antineoplaston therapy has on adult recurrent/progressive oligodendrogliomas.
|Condition or disease||Intervention/treatment||Phase|
|Oligodendroglioma, Adult||Drug: Antineoplaston therapy (Atengenal + Astugenal)||Phase 2|
OVERVIEW: This is a single arm, open-label study in which adults with recurrent/progressive oligodendrogliomas 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.
- To determine the efficacy of Antineoplaston therapy in adults with recurrent/progressive oligodendrogliomas, 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 with recurrent/progressive oligodendrogliomas.
- 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.

|Study Completion Date :||September 2007|
Experimental: Antineoplaston therapy
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)
Adults with a recurrent/progressive Oligodendroglioma will receive Antineoplaston therapy (Atengenal + Astugenal).
Other Name: A10 (Atengenal); AS2-1 (Astugenal)
- Number of Participants With Objective Response [ Time Frame: 12 months ]Objective response rate per Response Assessment in Neuro-Oncology (RANO) for target lesions and assessed by MRI: Complete Response (CR), disappearance of all disease sustained for at least four weeks; Partial Response (PR), >=50% decrease in the sum of the products of of the greatest perpendicular diameters of all measurable enhancing lesions, sustained for at least four weeks.
- Percentage of Participants Who Survived [ Time Frame: 6 months, 12 months, 24 months, 36 months, 48 months, 60 months ]6 months, 12 months, 24 months, 36 months, 48 months, 60 months overall survival
