Exclusion Criteria

Exclusion criteria
•Inherited or acquired bleeding disorder other than severe hemophilia A
•Use of systemic immunomodulators (e.g., interferon) at enrollment or planned use
•during the study
•Receipt of any of the following:
– An investigational drug to treat or reduce the risk of hemophilic bleeds within 5 drug-elimination half-lives of last drug administration
– A non-hemophilia-related investigational drug within the last 30 days or 5 drug-elimination half-lives, whichever is shorter
– An investigational drug concurrently
– Prior use of emicizumab prophylaxis including investigational or commercial emicizumab
•Current active severe bleed, such as ICH
•Planned surgery during the study
•History of clinically significant hypersensitivity associated with monoclonal antibody therapies or components of the emicizumab injection
•Patients who are at high risk for TMA (e.g., have a previous medical or family history of TMA, such as thrombotic thrombocytopenic purpura, atypical hemolytic uremic syndrome) in the investigator's judgment
•Previous or current treatment for thromboembolic disease or signs of thromboembolic disease
•Any hereditary or acquired maternal condition that may predispose the patient to thrombotic events

•Known infection with HIV, hepatitis B virus, or hepatitis C virus
•Serious infection requiring antibiotics or antiviral treatments within 14 days prior to screening
•Concurrent disease, treatment, abnormality in clinical laboratory tests, vital signs measurements, or physical examination findings that could interfere with the conduct of the study or that would, in the opinion of the investigator or Sponsor, preclude the patient’s safe participation in and completion of the study or interpretation of the study results
•Unwillingness of the parent or caregiver to allow receipt of blood or blood products, or any standard-of-care treatment for a life-threatening condition
