Related Conditions & MeSH terms

• Hemophilia A

Intervention

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.
