About this study

Official title: Phase II Study of Phenylacetate in Pediatric Patients With Central Nervous System Tumors

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die.

PURPOSE: Phase II trial to study the effectiveness of phenylacetate in treating children with recurrent or progressive brain tumors.

Read the detailed description

OBJECTIVES: I. Determine the efficacy of phenylacetate in terms of response rate and time to progression in children with recurrent or progressive brain tumors, or with previously untreated poor prognosis brain tumors. II. Assess the toxicity of phenylacetate in these patients treated at the maximum tolerated dose. III. Determine the correlation between serum steady state phenylacetate levels and toxicity or response in these patients.

OUTLINE: Patients are stratified by histologic type (anaplastic astrocytoma and glioblastoma multiforme vs brain stem glioma vs medulloblastoma and primitive neuroectodermal tumors vs ependymoma vs low grade glioma vs others). Patients receive phenylacetate as a continuous intravenous infusion on days 1-28. Courses of treatment are given continuously without rest. Treatment continues in the absence of disease progression or unacceptable toxicity. Patients are followed weekly.

PROJECTED ACCRUAL: A total of 9-30 patients per stratum will be accrued for this study in 2 years.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing phenylacetate in people with Brain and Central Nervous System Tumors, run by Texas Children's Cancer Center at 6 sites 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 26 Jun 2013. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 6 sites 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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.

Where can I read the original study information?
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 26 Jun 2013.
