What this trial studies

This study evaluates the effectiveness of Nuwiq, a recombinant factor VIII, in preventing bleeding during major surgery in male patients over 12 years old with severe hemophilia A who are already receiving emicizumab prophylaxis. It is a prospective, open-label, uncontrolled, single-arm, multinational, multicenter study. The aim is to assess the overall perioperative hemostatic efficacy of Nuwiq in this specific patient population. Participants must have a history of severe hemophilia A and have been on emicizumab for at least one month prior to surgery.

Who should consider this trial

Good fit: Ideal candidates are male patients aged 12 and older with severe hemophilia A who have been on emicizumab prophylaxis and require major surgery.

Not a fit: Patients with other coagulation disorders, FVIII inhibitors, severe liver or kidney disease, or known hypersensitivity to Nuwiq will not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly improve bleeding management during surgeries for patients with severe hemophilia A.

How similar studies have performed: Other studies have shown promising results with similar approaches in managing bleeding in hemophilia patients, indicating potential for success.
