Antineoplaston Therapy in Treating Patients With Stage IV Adrenal Gland Cancer

Phase II Study of Antineoplastons A10 and AS2-1 In Patients With Carcinoma of the Adrenal Gland

Current therapies for Stage IV adrenal gland cancer provide very limited benefit to the patient. The anti-cancer properties of Antineoplaston therapy suggest that it may prove beneficial in the treatment of Stage IV adrenal gland cancer

PURPOSE: This study is being performed to determine the effects (good and bad) that Antineoplaston therapy has on patients with Stage IV adrenal gland cancer.

OVERVIEW: This is a single arm, open-label study in which patients with Stage IV adrenal gland cancer receive gradually escalating doses of intravenous Antineoplaston therapy (Atengenal + Astugenal) until the maximum tolerated dose is reached. Treatment continues up to12 months in the absence of disease progression or unacceptable toxicity.

OBJECTIVES:

• To determine the efficacy of Antineoplaston therapy in patients with Stage IV adrenal gland cancer, 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 patients with Stage IV adrenal gland cancer.
• 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.

DISEASE CHARACTERISTICS:

• Histologically confirmed stage IV adrenal gland carcinoma that is unlikely to respond to existing therapy and for which no curative therapy exists
• Measurable disease by MRI or CT scan
• Tumor must be greater than 2 cm at the largest diameter for the lymph nodes located in the head, neck, axillary, inguinal, or femoral areas and at least 0.5 cm in the largest diameter for other localizations
