An observational study of Migraine, run by Samsung Medical Center at 1 site in South Korea.

Trial summary

Brain white matter hyperintensities (WMHs) are prevalent in migraineurs, of which the mechanism is still unclear. The investigators aimed to test the spatial association between areas with reduced cerebrovascular reactivity (CVR) to hypercapnic stimuli and consequent development of WMHs.

About this study

Official title: Research of Brain White Matter Hyperintensity in Migraine Using a Cerebrovascular Reactivity Mapping Based on BOLD MRI

Brain white matter hyperintensities (WMHs) are prevalent in migraineurs, of which the mechanism is still unclear. The investigators aimed to test the spatial association between areas with reduced cerebrovascular reactivity (CVR) to hypercapnic stimuli and consequent development of WMHs.

Read the detailed description

A whole-brain map of CVR will be created in patients with migraine and normal controls. Hypercapnic stimuli for CVR will be delivered by prospective end-tidal CO2 targeting device. Hemodynamic responses will be determined by BOLD signal changes using fMRI. WMHs will be determined by high-resolution 3D FLAIR imaging. Patients and controls will undergo serial MRIs with 1 year interval. Associations between areas of reduced CVR and consequent WMH development will be tested in both patients and controls.

What participants receive

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

  • BOLD MRIDiagnostic test

    1. Prospective End-tidal targeting RespirAct device(A specially designed gas blender and sequential rebreathing circuit) will be used to implement the gas targeting method which involves precise elevations in End-tidal PCO2 while maintaining a fixed End-tidal PO2
    2. BOLD MR images will be obtained by using a T2*-weighted two-dimensional gradient-echo sequence with echoplanar readout.

ControlNormal controls without headaches will undergo BOLD MRI with prospective CO2 targeting

MigraineursPatients diagnosed with migraine based on the ICHD-3 beta will undergo BOLD MRI with prospective CO2 targeting
Receives: Diagnostic Test: BOLD MRI

What is being measured

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

  1. CVR association with WMH development

    The investigators will obtain a CVR map using BOLD MR signal in the first year of study and also obtain changes in WMH during 2 years of follow-up period in patients and controls, respectively. Then the investigators will test whether CVR-map predicts consequent WMH development in patients and controls, respectively.

    Measured: 1-year follow-up (2nd year)

Secondary outcomes (1)
  1. Spatial pattern of CVR

    The investigators will obtain a CVR map for each voxel using BOLD MR signal in response to % increase in EtCO2 respectively in patients and controls. Spatial pattern of CVR will be compared between patients and controls.

    Measured: baseline(1st year)

Questions about this trial

What is this clinical trial studying?

An observational study of Migraine, run by Samsung Medical Center at 1 site in South Korea.

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 11 inclusion and 9 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 10 Apr 2019. 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 South Korea. 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.

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?

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?

CVR association with WMH development (time frame: 1-year follow-up (2nd year)). 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 10 Apr 2019.
