NCT00003469
First received: November 1, 1999

  Purpose

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

PURPOSE: This study is being performed to determine the effects (good and bad) that Antineoplaston therapy has on children (> 6 months of age) with Rhabdoid tumors.


Condition Intervention Phase
Rhabdoid Neoplasm of CNS
Drug: Antineoplaston therapy (Atengenal + Astugenal)
Phase 2

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment
Official Title: Phase II Study of Antineoplastons A10 and AS2-1 in Children With Rhabdoid Tumor of the Central Nervous System

Primary Outcome Measures:
  • Number of Participants With Objective Response [ Time Frame: 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.


Secondary Outcome Measures:
  • Percentage of Participants Who Survived [ Time Frame: 6 months, 12 months, 24 months ]
    6 months, 12 months, 24 months overall survival


Enrollment: 4
Study Start Date: February 1996
Study Completion Date: May 2003
Primary Completion Date: May 2003 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
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)
Children with a Rhabdoid tumor will receive Antineoplaston therapy (Atengenal + Astugenal).
Other Name: A10 (Atengenal); AS2-1 (Astugenal)

Detailed Description:

OVERVIEW: This is a single arm, open-label study in which children with Rhabdoid tumors 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.

OBJECTIVES:

  • To determine the efficacy of Antineoplaston therapy in children with a Rhabdoid tumor, 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 Rhabdoid tumor.
  • 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.
