Summary
An open-label, single-arm, post- authorization pragmatic clinical trial on the safety and efficacy of Xyntha (Moroctocog-alfa (AF-CC), Recombinant FVIII) in subjects with hemophilia A in usual care settings in China for approximately 6 months or or approximately 50 exposure days whichever occurs first
Eligibility Criteria
Inclusion Criteria
- Male and/or Female subjects with Hemophilia A.
- Subjects/parents/legal representatives must be able to comply with registry procedures (informed consent/assent process, clinical visits, reporting of infusion and bleed data, reporting of adverse events, etc).
- Evidence of a personally signed and dated informed consent document indicating that the subject (or a legally acceptable representative, parent(s)/legal guardian) has been informed of all pertinent aspects of the study.
Exclusion Criteria
- Presence of any other bleeding disorder in addition to hemophilia A.
- Treatment with immunomodulatory therapy (e.g., intravenous immunoglobulin, routine systemic corticosteroids, cyclosporins, anti-TNF agents) within 30 days prior to study entry or planned use for the duration of their study participation.
- Subjects with a past history of, or current factor VIII inhibitor. For laboratory-based assessments, any Bethesda inhibitor titer greater than the laboratory's normal range or ≥0.6 BU/mL.
- Subjects with known hypersensitivity to the active substance or to any of the excipients of Xyntha.
- Subjects with a known hypersensitivity to Chinese Hamster Ovary cell proteins.
- Unwilling or unable to follow the terms of the protocol.
- Any condition which may compromise the subject's ability to comply with and/or perform study-related activities or that poses a clinical contraindication to study participation (these conditions include, but are not limited to, inadequate medical history to assure study eligibility; expectation of poor compliance in provision of observations for study-related documentation), in the opinion of the Investigator.
- Participation in other studies involving investigational drug(s) (Phases 1-4) within 30 days before the current study begins and/or during study participation (exception for studies on Xyntha).
- Subjects who are investigational site staff members directly involved in the conduct of the study and their family members, site staff members otherwise supervised by the Investigator, or subjects who are Pfizer employees directly involved in the conduct of the study.
