Brief Summary

Current therapies for Adenocarcinoma of the Esophagus provide limited benefit to the patient. The anti-cancer properties of Antineoplaston therapy suggest that it may prove beneficial in the treatment of Adenocarcinoma of the Esophagus.

PURPOSE: This study is being performed to determine the effects (good and bad) that Antineoplaston therapy has on patients with Adenocarcinoma of the Esophagus.

Detailed Description

Esophageal cancer patients receive gradually escalating doses of intravenous Antineoplaston therapy (Atengenal + Astugenal) until the maximum tolerated dose is reached. Treatment continues up to 12 months in the absence of disease progression or unacceptable toxicity.

OBJECTIVES:

• To determine the efficacy of Antineoplaston therapy in patients with esophageal 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 Esophageal Cancer.
• To determine objective response, tumor size is measured utilizing physical examination, and radiologic studies 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.

Conditions

Adenocarcinoma of the Esophagus

Study Design

• Allocation Method: NA
• Intervention Model: SINGLE_GROUP
• Primary Study Purpose: TREATMENT
• Blinding Strategy: NONE

Study Groups

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.

Group Type: EXPERIMENTAL

Antineoplaston therapy (Atengenal + Astugenal)

Intervention Type: DRUG

Patients with Adenocarcinoma of the Esophagus 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.
