About this study

Official title: Development of Magnetic Resonance Spectroscopy (MRS) Biomarkers of Tumor Metabolism

This study will evaluate the test-retest repeatability of lactate and other metabolites measured by single voxel magnetic resonance spectroscopy (MRS) and multi-voxel magnetic resonance spectroscopic imaging experiments (MRSI) in tumor tissue in patients radiographically diagnosed with glioma.

These measurements will test whether the concentration of lactate in tumor will be higher than the concentration of lactate in normal tissue of the same patient.

What is being measured

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

  1. The test-retest repeatability of lactate and other metabolites when measured by multi-voxel MRSI in tumor tissue

    Measured: 90 minutes

  2. The test-retest repeatability of lactate and other metabolites when measured by single voxel MRS

    Measured: 90 minutes

Secondary outcomes (6)
  1. The geometric mean fold rise (GMFR) in the concentrations of lactate and each of the other metabolites for tumor/normal tissue

    Measured: 90 minutes

  2. The test-retest repeatability of lactate and other metabolites when measured by multi-voxel MRSI in normal tissue

    Measured: 90 minutes

  3. True geometric mean ratio (GMR) of the MRSI/SV MRS concentration values

    Measured: 90 minutes

  4. The mean levels of each of the metabolites will be summarized by tumor grade and type

    Measured: 90 minutes

  5. The correlation between in vivo (measured by MRSI) and in vitro levels of lactate and other metabolites in tumors

    Measured: 90 minutes

  6. The within day and between day standard deviations for each metabolite

    Measured: 90 minutes

Questions about this trial

What is this clinical trial studying?

An observational study of Glioma, run by Merck Sharp & Dohme LLC.

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 2 inclusion and 4 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: finished, as of the sponsor's last update on 12 Oct 2015. Status can change between updates, so confirm with the study contact before making plans.

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.

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.

What does the primary outcome measure?

The test-retest repeatability of lactate and other metabolites when measured by multi-voxel MRSI in tumor tissue (time frame: 90 minutes). The study lists 2 primary outcomes in all. 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 NCT01138813, 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 12 Oct 2015.
