Antineoplaston Therapy in Treating Patients With Recurrent or Stage IV Lung Cancer

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