New biomarkers for ischemic cerebrovascular disease

A Prospective Observational Cohort Study of Predictive Biomarkers Related With Ischemic Cerebrovascular Disease

Observational Tongji Hospital · NCT06890702

This study will test whether specific blood, cerebrospinal fluid, urine, and stool biomarkers can help diagnose and predict outcomes for people with ischemic stroke and related cerebrovascular conditions.

What this trial studies

This is a single-center, prospective observational study that compares patients with ischemic cerebrovascular disease to age- and sex-matched healthy controls from a medical check-up center. Participants provide blood, cerebrospinal fluid, urine, and stool samples, undergo clinical imaging (CT, MRI, PET-CT) and functional assessments, and are followed at 3, 6, 12, 24, 36, and 48 months to track clinical outcomes and biomarker changes. Researchers will analyze biomarker expression differences and combine clinical and laboratory data to build a prediction model for diagnosis, progression, and treatment response. Data access is governed by an independent review panel and secure data-sharing agreements, with source data verified by certified neurologists.

Who should consider this trial

Good fit: Ideal candidates are adults diagnosed with ischemic cerebrovascular disease (including TIA, ischemic stroke, chronic cerebral hypoperfusion, or related conditions) or age- and sex-matched healthy volunteers who can provide biological samples and attend scheduled follow-ups.

Not a fit: Patients with cerebral hemorrhage, those with severe systemic disease expected to survive less than three months, or those unable to provide ongoing follow-up are unlikely to benefit from this study.

Why it matters

Potential benefit: If successful, the findings could enable earlier diagnosis, more individualized treatment planning, and better prognosis prediction for people with ischemic cerebrovascular disease.

How similar studies have performed: Previous biomarker research in stroke has produced some promising but inconsistent results, so similar approaches are plausible but not yet definitively proven.
