Comparing blood-thinning therapies for patients with severe intracranial artery narrowing
Official title: Comparison of Anti-coagulation and Anti-Platelet Therapies for Intracranial Vascular Atherostenosis- Magnetic Resonance Imaging
Run by Yale University · NCT05907629 · Data updated 2026-11-12
This study is testing how well different blood-thinning medications work for stroke patients with severe narrowing of the arteries in the brain, using MRI scans to find out who might not be responding to treatment.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are individuals who have experienced a nondisabling ischemic stroke due to severe intracranial artery narrowing and are enrolled in the CAPTIVA trial.
✕Probably not a fit
Patients who are unable to undergo MRI or have contraindications to MRI will not benefit from this study.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This observational study, known as CAPTIVA-MRI, is designed to analyze MRI biomarkers in patients with severe intracranial atherosclerotic stenosis (ICAS) who have experienced a stroke. It is an ancillary study to the CAPTIVA trial, which involves randomizing patients to different blood-thinning medications. The primary aim is to identify patients who do not respond to the best medical management through advanced MRI imaging techniques. The findings are expected to inform future ICAS trials and improve patient management strategies.
Why it matters
Potential benefit: If successful, this study could lead to better identification of patients who need alternative treatments for ICAS, potentially reducing the risk of future strokes.
How similar studies have gone: Other studies have shown promise in using MRI biomarkers for similar conditions, but this specific approach is relatively novel.
