  Purpose

RATIONALE: Antineoplastons are naturally-occurring substances that may also be made in the laboratory. Antineoplastons may inhibit the growth of cancer cells.

PURPOSE: This phase II trial studies the effectiveness of antineoplaston therapy in treating women who have stage IV breast cancer that has not responded to previous therapy.

Enrollment: 19
Actual Study Start Date: March 18, 1996
Study Completion Date: December 28, 2002
Primary Completion Date: December 28, 2002 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
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)

Patients with Stage IV Breast Cancer 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.

Other Name: A10 (Atengenal); AS2-1 (Astugenal)

Detailed Description:

OVERVIEW: This is a single arm, open-label study in which patients with Stage IV breast 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 breast 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 breast 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.
