Predicting outcomes for patients with brain bleeding on specific blood thinners

Forecast of Functional Outcome and Impact of Anti Factor Xa-levels in Patients With Intracerebral Haemorrhage Related to Direct Factor Xa Inhibitors - a Multi-center Cohort Study

Insel Gruppe AG, University Hospital Bern · NCT06383741

This study is testing how well certain blood thinners work for patients who have bleeding in the brain and whether specific treatments can help improve their recovery after 30 days.

What this trial studies

This observational study investigates the outcomes of patients who experience intracerebral hemorrhage (ICH) while on direct factor Xa inhibitors and dabigatran, which are commonly used for stroke prevention. It aims to assess the hemostatic efficacy of treatments like prothrombin complex concentrate and andexanet alfa, while also evaluating 30-day functional outcomes. The study will measure anti-FXa levels to guide treatment decisions and explore their relationship with hematoma expansion, particularly in patients presenting late after drug intake.

Who should consider this trial

Good fit: Ideal candidates include patients with imaging-proven intracerebral hemorrhage who have been on a factor Xa inhibitor without interruption for more than 48 hours prior to symptom onset.

Not a fit: Patients who have received additional treatment with Vitamin K antagonists or dabigatran will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve treatment strategies for patients experiencing ICH while on anticoagulants, potentially leading to better recovery outcomes.

How similar studies have performed: While there are ongoing studies like ANNEXA-I assessing similar treatment strategies, direct comparative evidence remains limited, making this study's approach somewhat novel.
