About this study

Official title: Combined Role of PET and MEG in Nonlesional Epilepsy in Pediatric Population

The first aim of this study are to evaluate the lobar concordance of FDG-PET and MEG with intracranial electrographic study in children with intractable partial epilepsy. The second aim is to determine if the combined role of FDG-PET and MEG improve detection of epileptogenic zone as defined by invasive intracranial recordings.

Read the detailed description

Children with poorly controlled epilepsy are extensively investigated with various tools including MR brain, electroencephalography (EEG), magnetoencephalography (MEG) or position emission tomography (PET) scans. When MR brain does not show an abnormality, the patient is said to have nonlesional epilepsy. In these cases, it is even more crucial to be able to identify the epileptogenic zone, depending on availability of investigative tool.

Recognizing that individual modalities have limitations, the aim of this study is to determine if combining non-invasive investigations with MEG and PET, which respectively evaluate the electrical and metabolic activity of the brain, could improve the children with intractable nonlesional epilepsy with MEG and PET and compared this with invasive intracranial monitoring. The endpoint of the study being agreement on localizations of epileptogenic zone using PET and MEG individually and in combination and comparing this with invasive intracranial monitoring.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • magnetoencephalographyDevice

    MEG studies are performed using a whole-head Omega 151-channel gradiometer system.

  • Positron emission tomography (PET)Device

    An interictal FDG(fluoro-D-glucose)-PET will be obtained in a single 10 minute scanning session. PET scans will be obtained using a 3D acquisition technique, which will allow the use of a lower dose of radiotracer.

  • Magnetic resonance imagingDevice

    MR will be performed on a 1.5T or 3T system, using a combination of different sequences including sagittal T1, coronal and axial T2, FLAIR and proton density and axial 3D T1 weighted images.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing magnetoencephalography, Positron emission tomography (PET) and Magnetic resonance imaging in people with Epilepsy, run by The Hospital for Sick Children at 1 site in Canada.

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 1 inclusion and 1 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 13 May 2014. 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 Canada. 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 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 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 concordance rate of FDG-PET and MEG with video EEG (time frame: 3 years). 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 13 May 2014.
