Direct Oral Anticoagulants for the Treatment of Cerebral Venous Thrombosis: An International Phase IV Study

Academisch Medisch Centrum - Universiteit van Amsterdam (AMC-UvA) · NCT04660747

What this trial studies

This observational study aims to evaluate the safety and efficacy of direct oral anticoagulants (DOACs) in patients diagnosed with cerebral venous thrombosis (CVT). Traditionally, patients have been treated with vitamin K antagonists (VKAs), but DOACs may offer a more practical alternative with a lower risk of complications. The study will include patients who have started anticoagulant treatment within 30 days of their CVT diagnosis and will gather data on their outcomes over time. The goal is to provide additional evidence on the use of DOACs for this condition, building on previous findings from the RESPECT-CVT trial.

Who should consider this trial

Good fit: Ideal candidates for this study are adults over 18 years old with a confirmed diagnosis of cerebral venous thrombosis who have started anticoagulant treatment within 30 days of diagnosis.

Not a fit: Patients who are currently on anticoagulant treatment at the time of CVT diagnosis or have severe renal or liver disease may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a safer and more effective treatment option for patients with cerebral venous thrombosis.

How similar studies have performed: Previous studies, such as the RESPECT-CVT trial, have shown promising results for the use of DOACs in treating CVT, indicating potential for success in this observational study.
