Descrição
Inclusion Criteria:
- Severe hemophilia A is defined as a baseline factor VIII level <1%. A history of inhibitor is defined as ever having a Bethesda titer > 1 BU.
Phase I.
Subjects with hemophilia are eligible for Phase I of the study if all of the following apply:
- An informed consent form, approved by the appropriate IRB/IEC, has been administered, signed, and dated.
- The subject has severe hemophilia A.
- The subject has a history of inhibitor or the subject has no history of inhibitor but has at least 100 exposure days to factor VIII products.
- Sufficient documentation exists to identify the subject's maximum lifetime Bethesda titer.
- The subject has a history of inhibitor and has one or more full brothers with severe hemophilia A, with or without an inhibitor, who are eligible for and have agreed to be in the study, and two parents who have agreed to be in the study or the subject does not have a history of inhibitor but has one or more full brothers with severe hemophilia A and a history of inhibitor who are eligible for and have agreed to be in the study, and two parents who have agreed to be in the study.
Subjects without hemophilia are eligible for Phase I of the study if all of the following apply:
- An informed consent form, approved by the appropriate IRB/IEC, has been administered, signed, and dated.
- The subject is the parent (mother or father) of, or the full sibling of, a subject with hemophilia who is eligible for Phase I of the study.
Phase II.
Subjects with hemophilia are eligible for Phase II of the study if all of the following apply:
- An informed consent form, approved by the appropriate IRB/IEC, has been administered, signed, and dated.
- The subject has severe hemophilia A.
- The subject has a history of inhibitor and two parents who have agreed to be in the study.
- Sufficient documentation exists to identify the subject's maximum lifetime Bethesda titer.
Subjects without hemophilia are eligible for Phase II of the study if all of the following apply:
- An informed consent form, approved by the appropriate IRB/IEC, has been administered, signed, and dated.
- The subject is the parent (mother or father) of a subject with hemophilia who is eligible for Phase II of the study.
Exclusion Criteria:
Phase I.
Subjects (with or without hemophilia) are excluded from participation in Phase I if:
- The minimum family group, defined as a pair of full brothers with hemophilia, either concordant (both with) or discordant (one with, one without) for inhibitor, and both of their parents, is not enrolled.
Phase II.
Subjects are excluded from participation in Phase II if:
- The minimum family group, defined as a person with hemophilia and a history of inhibitor and his mother and father, is not enrolled.
