About this study

PET imaging of activated microglia offers a tool of investigation of a range of brain diseases where neuroinflammation is a component.

Amyotrophic lateral sclerosis is the most frequent motoneuronal disease in adult.

This study was designed to explore the feasibility of molecular imaging modality by Positron Emission Tomography using 18F-X as an in vivo marker of activated microglia for the assessment of neuroinflammation in amyotrophic lateral sclerosis.

PET may help in the diagnosis of the disease and, further, may allow assessment of the efficacy of antiinflammatory treatment.

Read the detailed description

18F-X PET will be carried out requiring arterial sampling in 2 patients suffering from ALS and 2 normal subjects in order to evaluate the 18F-X quantification.

Then simplified PET using 18F-X will be carried out in 13 patients and 13 normal subjects.

Binding potential maps showing specific binding of 18f-X will be generated for each subject.

Regional binding potential values will be calculated for anatomically defined regions of interest after coregistration to and special transformation into the subject's own MRI.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing 18F-X PET SCAN in people with Amyotrophic Lateral Sclerosis and Bulbar Disease, run by University Hospital, Tours at 1 site in France.

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 3 inclusion and 5 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: status not confirmed, as of the sponsor's last update on 19 Mar 2010. 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 France. 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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

Are results available for this study?

Results are not available in the source record.

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

Contact Catherine ROUSSEL ((33) 2.47.47. 97.89, roussel@med.univ-tours.fr), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Quantitative in vivo-imaging of 18F-X microglial binding site as a mesure of disease activity followed up by non invasive quantification of patients using imaging modality. (time frame: Inclusion period). 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 NCT00563537, which also lists 6 linked publications.

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 19 Mar 2010.
