About this study

Official title: Carbon-11-Sodium Acetate Positron Emission Tomography/Computed Tomography (PET/CT) Imaging Evaluation in Brain Glioma, Post Therapy Necrosis and Pseudo-progression

This study will investigate how well Carbon Acetate PET/CT imaging helps to correctly identify recurrent tumor versus post treatment effects (radionecrosis) in patients with previously treated high grade brain gliomas.

Read the detailed description

The study is designed to investigate the effectiveness of Carbon Acetate PET/CT (AC PET)in terms of its ability to distinguish between radionecrosis/pseudo-progression and viable tumor in patients previously treated with surgery and radiation for high grade glioma brain tumors.

Eligible patients with biopsy proven high grade gliomas (WHO grades 3 and 4) status-post prior cranial irradiation for this tumor; age 18 to 70; ECOG/Zubrod of 0-2, no other contraindications to trial entry, and a post-irradiation cranial MRI or CT demonstrating an enhancing lesion of uncertain etiology (not biopsied) will be treated with at least two weeks of steroidal therapy.

Responders to steroidal therapy will be classified as either pseudo-progression (if asymptomatic) or radionecrosis (if symptomatic). Non-responders (those who do not respond clinically, radiographically, or both) will be referred for an FDG PET/CT and initial AC PET/CT within 3 weeks, and subsequently referred for stereotactic biopsy of their lesion followed by focal laser treatment (in the same operative setting) within 3 weeks of AC PET/CT.

Specific Goals/Questions:

  1. What is the yield (sensitivity, accuracy, positive and negative predictive value) of state-of-the-art PET/CT with C-11 Acetate in detecting recurrent disease versus post treatment effects and pseudo-progression in this patient population?
  2. How does the performance of PET with C-11 Acetate compare with that of PET using F-18 fluorodeoxyglucose (FDG-PET) and with that of MRI?
  3. Evaluate the optimal timing for post injection imaging.

What is being measured

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

  1. Biopsy Correlation

    AC PET imaging results will be correlated with tissue biopsy results

    Measured: 3 weeks from AC PET Imaging

Secondary outcomes (1)
  1. SUV (Standardized Uptake Value)

    Imaging studies will be evaluated both qualitatively and quantitatively using SUV (standardized uptake values): a measure of metabolism based on injected dose, patient weight and region of interest. Comparison of the lesional activity to normal contralateral tracer activity will also be measured.

    Measured: Day 1 - Assess at time of PET imaging

Questions about this trial

What is this clinical trial studying?

A Phase 2/3 study testing Sodium Acetate C11 PET/CT Imaging in people with Gliomas, run by Phoenix Molecular Imaging 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?

The sponsor lists 10 inclusion and 2 exclusion criteria. 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: withdrawn, as of the sponsor's last update on 28 Sep 2016. 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 combined 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.

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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 was withdrawn before enrolling participants, so there are no results.

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?

Biopsy Correlation (time frame: 3 weeks from AC PET Imaging). It is what the study was designed to measure, not a finding.

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 28 Sep 2016.
