Group/Cohort Intervention/treatment
Previously treated patient (PTPs) with hemophilia A
Previously treated patients with hemophilia A receiving damoctocog alfa pegol with any kind of treatment modality (on-demand, prophylaxis, or intermittent prophylaxis)。
Drug: Damoctocog alfa pegol (Jivi, Bay94-9027)
Follow clinical practice. BAY94-9027 is a B-domain-deleted recombinant factor VIII (rFVIII) product site-specifically conjugated to a single (dual 30-kDa branched) 60-kDa polyethylene glycol (PEG) molecule. BAY 94-9027 is intended for prophylaxis and treatment of bleeds in patients with hemophilia A aged ≥12 years, with a narrow, predictable weekly dose that allows for the treatment regimen to be tailored to individual patient needs.
