Study Details

Study Description

Brief Summary

RATIONALE: Current therapies for patients with ependymoma provide limited benefit to the patient. The anti-cancer properties of Antineoplaston therapy suggest that it may prove beneficial in the treatment of patients with ependymoma .

PURPOSE: This study is being performed to determine the effects (good and bad) that Antineoplaston therapy has on patients with ependymoma.

Condition or Disease Intervention/Treatment Phase
  • Drug: Antineoplaston therapy (Atengenal + Astugenal)
Phase 2

Detailed Description

OBJECTIVES:
  • To determine the efficacy of Antineoplaston therapy in patients with ependymoma 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 ependymoma

OVERVIEW: This is a single arm, open-label study in which patients with ependymoma 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

Arms and Interventions

Arm Intervention/Treatment
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 an ependymoma will receive Antineoplaston therapy (Atengenal + Astugenal).
Other Names:
  • A10 (Atengenal); AS2-1 (Astugenal)
  • Outcome Measures

    Primary Outcome Measures

    1. Number of Participants With Objective Response [12 months]

      Objective response rate per Response Assessment in Neuro-Oncology (RANO) for target lesions and assessed by MRI: Complete Response (CR), disappearance of all disease sustained for at least four weeks; Partial Response (PR), >=50% decrease in the sum of the products of of the greatest perpendicular diameters of all measurable enhancing lesions, sustained for at least four weeks; Stable Disease (SD), <50% decrease and <25% increase in the sum of the products of of the greatest perpendicular diameters of all measurable enhancing lesions, sustained for at least eight weeks; Progressive Disease (PD), >=25% increase in the sum of the products of of the greatest perpendicular diameters of all measurable enhancing lesions.

    Secondary Outcome Measures

    1. Percentage of Participants Who Survived [6 months, 12 months, 24 months, 36 months, 48 months, 60 months]
