Cortical Superficial Siderosis and Risk of Recurrent Intracerebral Hemorrhage in Cerebral Amyloid Angiopathy. (CORELIA)

December 23, 2025 updated by: University Hospital, Toulouse

COrtical Superficial Siderosis and REcurrent Lobar Intracerebral Hemorrhage in Cerebral Amyloid Angiopathy.

Cerebral amyloid angiopathy (CAA) is a major cause of lobar intracerebral hemorrhage (ICH) in the elderly with high risk of recurrence.

The investigators aim to determine the relationship between cortical superficial siderosis (cSS), a MRI hemorrhagic marker of CAA and the risk of symptomatic ICH recurrence in a multicentric prospective cohort of patients with acute lobar ICH related to CAA. The investigators hypothesize that patients with cSS have an increased risk of recurrent symptomatic ICH relative to those without cSS.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Patients with acute lobar ICH fulfilling the Boston criteria for probable or possible CAA will be enrolled within 30 days after ICH onset. Brain MRI performed at baseline will be analyzed blinded to clinical data. Patients with presence of cSS will be compared with those without cSS.

During a systematic follow-up of 24 months, patients will undergo neurological, neuropsychological and MRI evaluation. The investigators will compare the rate of recurrent symptomatic ICH at 24 months in patients with vs. without cSS.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

55 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Recurrent symptomatic intracerebral hemorrhage at 24 months
Time Frame: 24 months
Recurrent symptomatic intracerebral haemorrhage is defined as a further intracerebral hemorrhage documented by CT scan or MRI, associated with new neurologic symptoms

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
