About

Current therapies for metastatic or unresectable Colon 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 metastatic or unresectable Colon Cancer.

PURPOSE: This study is being performed to determine the effects (good and bad) that Antineoplaston therapy has on patients with metastatic or unresectable Colon Cancer

Full description

OVERVIEW: This is a single arm, open-label study in which patients with metastatic or unresectable Colon Cancer 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 metastatic or unresectable Colon 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 metastatic or unresectable Colon 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.

Enrollment: 15 patients

Sex: All

Ages: 18 to 99 years old
