About this study

Official title: Phase II Study of Antineoplastons A10 and AS2-1 Infusions in Children With Visual Pathway Glioma

RATIONALE: Current therapies for children with visual pathway gliomas, which are not amenable to or have not responded to standard therapy, provide limited benefit to the patient. The anti-cancer properties of Antineoplaston therapy suggest that it may prove beneficial in the treatment of children with visual pathway gliomas, which are not amenable to or have not responded to standard therapy.

PURPOSE: This study is being performed to determine the effects (good and bad) that Antineoplaston therapy has on children with visual pathway gliomas, which are not amenable to or have not responded to standard therapy.

Read the detailed description

OBJECTIVES:

  • To determine the efficacy of Antineoplaston therapy in children with visual pathway gliomas, which are not amenable to or have 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 visual pathway gliomas, which are not amenable to or have not responded to standard therapy.

OVERVIEW: This is a single arm, open-label study in which children with visual pathway gliomas, which are not amenable to or 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: Approximately 20-40 patients will be accrued to this study.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of Participants With Objective Response

    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 in the sum of the products of of the greatest perpendicular diameters of all measurable enhancing lesions and no Progressive Disease, sustained for at least four weeks. Progressive Disease (PD): >=25% increase in the sum of the products of of the greatest perpendicular diameters of all measurable enhancing lesions.

    Measured: 12 months

Secondary outcomes (1)
  1. Percentage of Participants Who Survived

    6 months, 12 months, 24 months, 36 months, 48 months, 60 months overall survival

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Antineoplaston therapy (Atengenal + Astugenal) in people with Visual Pathway Glioma, run by Burzynski Research Institute at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 24 Aug 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 16 Dec 2016). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number of Participants With Objective Response (time frame: 12 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00003477, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 24 Aug 2017.
