Observing surgical practices in patients with Hemophilia A or B treated with extended half-life factors

Study of Surgical Practices in Patient With Haemophilia A or B Treated With an Extended Half-life Recombinant Factor VIII-Fc or IX-Fc (ELOCTA®, ALPROLIX®)

Hospices Civils de Lyon · NCT06158334

This study looks at how well extended half-life treatments for Hemophilia A or B work during surgery to see if they keep patients safe and reduce the need for frequent infusions.

What this trial studies

This study observes the surgical management of patients with Hemophilia A or B who are treated with extended half-life recombinant factor VIII (Elocta®) or factor IX (Alprolix®). It aims to evaluate the haemostatic efficacy of these treatments during surgical procedures, focusing on their ability to maintain stable factor levels while minimizing infusion frequency. The study will include patients undergoing surgery while receiving these therapies, providing insights into their effectiveness in real-world surgical settings.

Who should consider this trial

Good fit: Ideal candidates include patients diagnosed with Hemophilia A or B who are scheduled for surgery and are being treated with Elocta® or Alprolix®.

Not a fit: Patients with other blood coagulation disorders, inhibitors to factor VIII or IX, or severe liver or renal disease may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance surgical outcomes and safety for patients with Hemophilia A and B by optimizing peri-operative management.

How similar studies have performed: Previous studies have demonstrated good haemostatic efficacy of extended half-life factors in surgical settings, suggesting a positive outlook for this observational study.
