Trial summary

Spontaneous intracerebral hemorrhage (ICH) remains a significant cause of morbidity and mortality around the globe. The most common etiology of nontraumatic spontaneous ICH is hypertensive arteriopathy (HA), while cerebral amyloid angiopathy (CAA) is the most prevalent cause of spontaneous lobar ICH in the elderly.

About this study

Spontaneous intracerebral hemorrhage (ICH) remains a significant cause of morbidity and mortality around the globe. The most common etiology of nontraumatic spontaneous ICH is hypertensive arteriopathy (HA), while cerebral amyloid angiopathy (CAA) is the most prevalent cause of spontaneous lobar ICH in the elderly. Both HA and CAA belong to the family of cerebral small vessel disease (cSVD). cSVD involves pathological processes that affect the arteries, arterioles, capillaries, and veins on the surface and beneath the brain. The resultant changes of cSVD in the brain vasculatures can be detected with neuroimaging, includes cerebral microbleeds, white matter hyperintensities, lacunes, dilated perivascular spaces, and brain atrophy.

Investigators of this study have probe into various imaging markers in patients with cSVD. Investigators found that the lacune and cerebral microbleeds location was related to distinct underlying etiology of cSVD. Further, investigators utilized amyloid PET study to directly quantified the cerebral amyloid burden, and demonstrated the correlation between amyloid deposition and deep/superficial microbleeds ratio. The association between cerebellum microbleeds, which is a novel marker for cSVD, and the underlying pathology in patient with spontaneous ICH has been investigated. Investigators also summarized and published the current research of different cSVD imaging markers and its implication on patient care.

Cerebrovascular reactivity (CVR) represents the phenomenon that cerebral vessels dilate or constrict in response to stimuli, which provides insights into the vascular reserve information. The vascular reserve parameter is complementary to steady-state vascular index, such as cerebral perfusion or other neuroimaging markers. Measurement of CVR using advanced MR techniques is an emerging technique with multiple potential clinical utilities, and impaired autoregulation may contribute to the pathogenesis of cSVD. Recently, diminished CVR under visual stimuli has been linked to vascular amyloid deposits and related vascular dysfunction. Clarifying the mechanism of cSVD-related brain injury would be an important step towards identifying candidate treatment approaches.

The goal of this study is to understand the features of CVR in patients with cSVD-related spontaneous ICH, for the purpose of establishing new biomarkers in cSVD diagnosis and understanding the underlying pathophysiology.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing brain MRI in people with Intracerebral Hemorrhage, run by National Taiwan University Hospital at 1 site in Taiwan.

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 4 inclusion and 7 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 24 Jan 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 Taiwan. 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 Bo-Ching Lee, MD (+886 972653442, bochinglee@gmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Intracerebral hemorrhage recurrence (time frame: The patients will be follow up in the outpatient clinic for 2 years.). 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 NCT03815513, which also lists 4 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 24 Jan 2019.
