Run by University Hospital, Strasbourg, France · NCT07314983 · Data updated 2026-11-12
This project will see if adults with severe hemophilia A who are on modern factor VIII prophylaxis can be safely treated with long-term blood thinners.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are adults (≥18) with severe hemophilia A (FVIII <1%) who are receiving or expected to require long-term anticoagulation and who have not objected to reuse of their medical data.
✕Probably not a fit
People unlikely to benefit include children, those with mild or moderate hemophilia A, patients who never receive anticoagulation, and individuals who have refused reuse of their records.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This observational project will collect clinical data from adult patients with severe hemophilia A who receive long-term anticoagulation while on modern factor VIII prophylaxis, including extended half-life products. Researchers will document the type and dose of anticoagulant, details of FVIII replacement, bleeding and thrombotic events, and other clinical outcomes. No interventional treatment will be assigned — the work uses routine care and medical records, with inclusion dependent on absence of objection to data reuse. All cases are being gathered at the Hemostasis Unit, CHU de Strasbourg, creating a focused single-center case series to inform safety and management strategies.
Why it matters
Potential benefit: If successful, this work could help doctors decide when and how to give long-term anticoagulants to people with severe hemophilia A who are on modern FVIII prophylaxis.
How similar studies have gone: This is largely novel — the investigators note no published cases of long-term anticoagulation in severe hemophilia A, though short-term anticoagulation and reports in milder hemophilia have been described.
