What this trial studies

This observational study aims to gather data on the use of emicizumab in infants and children aged 0-3 years with Hemophilia A. Researchers will collect information through a questionnaire regarding dosing, frequency, and indications for emicizumab, as well as surgical practices related to its use. The study will involve a multi-institutional, retrospective review of pediatric patients treated with emicizumab across several hemophilia treatment centers in the New England region. The goal is to better understand the current practices and considerations for using emicizumab as primary prophylaxis in this young population.

Who should consider this trial

Good fit: Ideal candidates for this study are infants and children aged 0-36 months diagnosed with congenital mild, moderate, or severe Hemophilia A who have been prescribed emicizumab.

Not a fit: Patients with acquired Hemophilia A or those with Hemophilia A and another bleeding disorder may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide valuable insights into optimizing treatment protocols for young children with Hemophilia A, potentially improving their health outcomes.

How similar studies have performed: While this study focuses on a specific age group and treatment, similar studies on emicizumab have shown promising results in older populations, indicating potential for success in this novel application.
