Overview

This complementary and alternative medicine (CAM) information summary provides an overview of the use of antineoplastons as treatments for people with cancer. The summary includes a brief history of the development of antineoplastons; a review of laboratory, animal, and human studies; and possible side effects associated with antineoplaston use.

This summary contains the following key information:

  • Antineoplastons are drugs composed of chemical compounds that are naturally present in the urine and blood. They are an experimental cancer therapy that is purported to provide a natural biochemical substance that is excreted and therefore lacking in people with cancer.
  • Antineoplastons were first proposed as a possible cancer treatment in 1976.
  • Antineoplastons were originally isolated from human urine but are now synthesized from readily available chemicals in the developer’s laboratory.
  • Antineoplastons are not approved by the U.S. Food and Drug Administration for the prevention or treatment of any disease.
  • No randomized controlled trials showing the effectiveness of antineoplastons have been published in the peer-reviewed scientific literature.
  • Antineoplaston side effects can include serious neurologic toxicity.
  • Nonrandomized clinical trials investigating the anticancer efficacy of antineoplastons are underway at the developer’s institute.

Many of the medical and scientific terms used in this summary are hypertext linked (at first use in each section) to the NCI Dictionary of Cancer Terms, which is oriented toward nonexperts. When a linked term is clicked, a definition will appear in a separate window.
