  4. Who are able to use a diary to document bleeding events and associated treatment
Exclusion Criteria
  1. With known thrombophilia
  2. With body weight greater than (>)150 kilogram (kg) or body mass index >40
  3. With known current inadequate hematologic function (eg, platelet count <100,000 per microliter [/mcL] and/or hemoglobin level <10 grams per deciliter [g/dL], <100 g/L), hepatic function (that is, total bilirubin >1.5*upper limit of normal [ULN] [excluding Gilbert syndrome], aspartate transferase and/or alanine aminotransferase levels >3*ULN; clinical signs or known laboratory or radiographic evidence consistent with cirrhosis of the liver) or renal function (that is, serum creatinine >2*ULN; based on medical records or available laboratory reports)
  4. With previous deep vein thrombosis and pulmonary embolism, myocardial infarction, or stroke
  5. With history of intolerance to subcutaneous injections
  6. With known current uncontrolled hypertension (systolic blood pressure >160 millimeter of mercury (mm Hg); diastolic blood pressure >100 mm Hg; based on medical records)
  7. With active cancer or requires therapy for cancer, except for basal cell carcinoma
  8. With concurrent participation in an interventional clinical trial
  9. With current or planned use of emicizumab

  12. With known Human Immunodeficiency Virus (HIV) infection with CD4 count (or T-cell count) of <200 cells/mcL within 24 weeks before enrollment
  13. With current or planned treatment with anticoagulant or antiplatelet drugs
  14. With any other significant conditions or comorbidities that, in the opinion of the Investigator or their designee, would make the participant unsuitable for enrollment

Arm && Interventions
GroupInterventionDescription
All Eligible ParticipantsNo InterventionAll Participants diagnosed with severe HemA with or without inhibitors, moderately severe to severe HemB, or HemB with inhibitors will be enrolled and continue to receive their usual hemophilia treatment regimen under SOC therapy. Bleeding episodes and treatment data will be collected during the prospective follow up period in a diary. No intervention will be administered as part of this study.
