About this study

Official title: Assessment of Hypoxic Tissues in Acute Ischemic Stroke With 18F-FMISOnidazole PET and Comparison With MRI : A Prospective Multicenter Study

This study is a French multicenter prospective study including 5 stroke units with available MRI and F-MISO PET for patients with acute ischemic stroke.

Background and Purpose: 18F-Fluoromisonidazole (FMISO) PET has been used to identify hypoxic tissues in animals and stroke patients. While MRI has become the gold standard acute stroke imaging, no published study has compared FMISO PET and MRI.

The aim of this prospective study is to identify hypoxic tissues in 40 patients with acute ischemic stroke with F-MISO PET and to compare the location and the outcome of these hypoxic cells with MRI datas (weighted diffusion and FLAIR) and to clinical outcome.

Read the detailed description

40 prospective patients (aged 18 to 85 years) will be included in the first 36 hours after ischemic stroke onset.

The study period will be 2 years. Included patients will have F-MISO PET followed by brain MRI (MRI-1)(diffusion, FLAIR, perfusion, TOF) as soon as possible after stroke onset (less than 36 hours). A second brain MRI (MRI-2) will be performed on day 7.

The aim of the study is to locate hypoxic tissues and to compare with ischemic tissues defined by diffusion and FLAIR MRI sequences, with MRI evolution, and with clinical status at day 7 and day 90.

Inclusion criterias

  • Patients aged 18-85 years with encephalic brain ischemic stroke,
  • defined stroke onset,
  • NIHSS 5 to 20,
  • F-MISO Pet and MRI available <36 hours after stroke onset,

What is being measured

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

  1. volume and location of F-MISO uptake in stroke patients

    Measured: acute phase of brain ischemia < 36 hours

Secondary outcomes (1)
  1. comparison of F-MISO uptake areas and ischemic lesions defined by weighted diffusion and FLAIR on

    Measured: acute phase of brain ischemia < 36 hours

Questions about this trial

What is this clinical trial studying?

A study testing PET and MRI in people with Ischemic Stroke, run by University Hospital, Toulouse.

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 5 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: withdrawn, as of the sponsor's last update on 9 May 2016. 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 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?

volume and location of F-MISO uptake in stroke patients (time frame: acute phase of brain ischemia < 36 hours). 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 9 May 2016.
