Can a simple blood test predict brain bleed risk in cavernous malformation patients?
NCT ID NCT01764529
First seen Jul 27, 2026 · Last updated Jul 28, 2026 · Updated 1 time
Summary
Cerebral cavernous malformations (CCMs) are clusters of abnormal blood vessels in the brain and spine that can bleed, causing strokes, seizures, and headaches. This study follows people with an inherited form of CCM to identify factors—such as genetics, gut microbiome, and blood markers—that influence disease severity and progression. The goal is to find measurable outcomes and biomarkers that could help select high-risk patients and monitor drug response in future clinical trials.
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 successful, this study could identify blood biomarkers and other factors that predict which patients are at highest risk of bleeding, helping to design future treatment trials.
- What could go wrong
- This is an observational study, not a treatment trial, so it will not directly test any therapy. The findings may not lead to immediate clinical changes.
