Treatment Study
Summary
Study start date: April 1, 1996
Actual date on which the first participant was enrolled.OBJECTIVES: To determine the efficacy of Antineoplaston therapy in children with primitive neuroectodermal tumors that has not responded to standard therapy, 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 children with a brain tumor. OVERVIEW: This is a single arm, open-label study in which children with primitive neuroectodermal tumors that have not responded to standard therapy receive gradually escalating doses of intravenous Antineoplaston therapy (Atengenal + Astugenal) until the maximum tolerated dose is reached. Treatment continues for at least 12 months in the absence of disease progression or unacceptable toxicity. After 12 months, patients with a complete or partial response or with stable disease may continue treatment. 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. PROJECTED ACCRUAL: A total of 20-40 patients will be accrued to this study.
