phase II clinical trials of A10 and AS2-1 (antineoplastons) infusions in patients with diagnosed primary malignant brain tumors
From December 1991 to December 1995, the National Cancer Institute (NCI) initiated phase II clinical trials of A10 and AS2-1 (antineoplastons) infusions in patients with diagnosed primary malignant brain tumors. Four years and more than a million dollars later, these studies were stopped before it was possible to determine the effectiveness of antineoplastons. Both NCI and Dr Burzynski, the developer of antineoplastons, accused one another of attempting to undermine the project.
