What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

Researchers in China are running a large observational study to understand what happens to people after an intracerebral hemorrhage, a type of bleeding stroke. The study plans to enroll about 10,000 adults with imaging-confirmed bleeding in the brain and 2,000 healthy adults at more than 30 hospitals. Participants with hemorrhage will be followed for up to 10 years, with check-ins at 3 months, 6 months, and yearly. The study collects clinical, imaging, lifestyle, and treatment data plus blood and urine samples. It does not assign any treatment; doctors continue to decide all care. The main goal is to describe the full range of functional outcomes at 90 days and find factors that predict recovery, recurrence, and death.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
If the study identifies reliable markers and prognostic models, doctors could better predict recovery and tailor care for people with intracerebral hemorrhage.
What could go wrong
This is an observational study, so it cannot prove cause and effect. Findings may not apply outside China, and long-term follow-up can be incomplete.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

Adults with imaging-confirmed spontaneous intracerebral hemorrhage presenting within 30 days after symptom onset to more than 30 participating hospitals in China are recruited consecutively. Adult healthy controls without neurologic disease are recruited from participating health examination programs and communities. The coordinating center is Xiangya Hospital, Central South University, Changsha, China.

Ages

18 years and older

Anyone

Healthy volunteers

Accepted

You do not need to have the condition being studied to take part.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria - Intracerebral Hemorrhage Cohort: * Age 18 years or older. * Intracerebral hemorrhage confirmed by head computed tomography and/or magnetic resonance imaging. * Hemorrhage located in a deep cerebral region, cerebral lobe, cerebellum, or brainstem. * Presentation to a participating hospital within 30 days after symptom onset. * Written informed consent and broad consent provided in accordance with the ethics-approved process. Exclusion Criteria - Intracerebral Hemorrhage Cohort: * Traumatic intracerebral hemorrhage. * Secondary intracerebral hemorrhage attributed to an arteriovenous malformation, ruptured aneurysm, moyamoya disease, cavernous malformation, hematologic disorder, hemorrhagic tumor, vasculitis, cerebral venous thrombosis, hemorrhagic transformation of cerebral infarction, or other prespecified secondary cause. * Mixed intracerebral hemorrhage involving multiple deep and lobar locations at onset. * Severe psychiatric disease that precludes study procedures or follow-up. * End-stage hepatic or renal failure. * Autoimmune disease judged by the investigator to materially affect study objectives. * Active malignant tumor. * Pregnancy. * Any other condition that the investigator judges makes participation inappropriate. Inclusion Criteria - Healthy Control Cohort: * Age 18 years or older. * Able to provide written informed consent. * No known history of intracerebral hemorrhage. Exclusion Criteria - Healthy Control Cohort: * Malignant tumor. * Neurologic disease, particularly any prior intracerebral hemorrhage. * Any other condition that the investigator judges makes participation inappropriate.
