What this trial studies

This observational study focuses on individuals aged 12 to 50 years with moderate or severe hemophilia A who are beginning prophylaxis with efanesoctocog alfa. Conducted across multiple centers in the US and Japan, the study aims to enroll 35 patients to assess their goal attainment and physical activity levels. Participants will use a smartphone-compatible activity tracking device to report their outcomes electronically. The study will provide insights into the effectiveness of the new prophylactic treatment in improving physical activity among this patient population.

Who should consider this trial

Good fit: Ideal candidates are individuals aged 12 to 50 years with moderate or severe hemophilia A who are newly starting prophylaxis with efanesoctocog alfa.

Not a fit: Patients with a current diagnosis of FVIII inhibitors or those who have used efanesoctocog alfa for prophylaxis in the past six months may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance understanding of how efanesoctocog alfa impacts physical activity and goal attainment in patients with hemophilia A.

How similar studies have performed: While this study is observational, similar approaches in assessing physical activity in hemophilia patients have shown promise, indicating potential for valuable insights.
