About this trial

This is an interventional treatment trial for Low-Grade Astrocytoma, Nos focused on measuring Recurrent/progressive adult low grade astrocytoma

Eligibility Criteria

DISEASE CHARACTERISTICS: Histologically or cytologically confirmed low-grade astrocytoma that has progressed, recurred, or persisted after initial therapy, including radiotherapy Previously treated with at least 1 prior standard therapy (e.g., radiotherapy, chemotherapy, immunotherapy, or cytodifferentiating agent) Measurable tumor by MRI scan performed within two weeks prior to study entry Tumor must be at least 5 mm No brain stem tumors PATIENT CHARACTERISTICS: Age: 18 and over Performance status: Karnofsky 60-100% Life expectancy: More than 2 months Hematopoietic: WBC at least 2,000/mm^3 Platelet count at least 50,000/mm^3 Hepatic: Bilirubin no greater than 2.5 mg/dL SGOT and SGPT no greater than 5 times upper limit of normal No hepatic failure Renal: Creatinine no greater than 2.5 mg/dL No renal insufficiency No history of renal conditions that contraindicate high dosages of sodium Cardiovascular: No uncontrolled hypertension No chronic heart failure No history of congestive heart failure No history of other cardiovascular conditions that contraindicate high dosages of sodium Pulmonary: No severe lung disease (e.g., chronic obstructive pulmonary disease) Other: Not pregnant or nursing Fertile patients must use effective contraception during and for 4 weeks after study participation No other concurrent serious disease No active infection PRIOR CONCURRENT THERAPY: Biologic therapy: See Disease Characteristics At least 4 weeks since prior immunotherapy and recovered No concurrent immunomodulating agents Chemotherapy: See Disease Characteristics At least 4 weeks since prior chemotherapy (6 weeks for nitrosoureas) and recovered No concurrent antineoplastic agents Endocrine therapy: Concurrent corticosteroids allowed Radiotherapy: See Disease Characteristics At least 8 weeks since prior radiotherapy and recovered Surgery: Must recover from prior surgery Other: No prior antineoplastons

5. Study Description

Brief Summary
RATIONALE: Current therapies for adult recurrent/progressive low grade astrocytoma provide limited benefit to the patient. The anti-cancer properties of Antineoplaston therapy suggest that it may prove beneficial in the treatment of adult recurrent/progressive low grade astrocytoma. PURPOSE: This study is being performed to determine the effects (good and bad) that Antineoplaston therapy has on adults with a recurrent/progressive low grade astrocytoma.
Detailed Description
OVERVIEW: This is a single arm, open-label study in which adults with a recurrent/progressive low grade astrocytoma 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 with a recurrent/progressive low grade astrocytoma, 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 a recurrent/progressive low grade astrocytoma. 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.

Arm Title
Antineoplaston therapy
Arm Type
Experimental
Arm Description
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.
Intervention Type
Drug
Intervention Name(s)
Antineoplaston therapy (Atengenal + Astugenal)
Other Intervention Name(s)
A10 (Atengenal); AS2-1 (Astugenal)
Intervention Description
Adults with a recurrent/progressive low grade astrocytoma 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.
