SAFE Study: Safety of aPCC Following Emicizumab Prophylaxis

Korábbi kezelés

• Had an active bleed requiring factor therapy at screening
• Previous or current treatment for thromboembolic disease or signs of thromboembolic disease (excluding previously resolved line-associated thrombosis)
• Had a surgical procedure 14 days before screening
• If the patient is treated with rFVIIa or aPCC seven days before screening
• Had current use of any medication other than emicizumab that could affect the coagulation system.
• Participants who are at high risk for TMA (for example, have a previous medical/family history of TMA), in the investigator's judgment

Más betegség

• Inherited or acquired bleeding disorder other than hemophilia A excluding low VWF (>30% VWF:RCo or VWF:GP1bm)
• Conditions that may increase the risk of bleeding or thrombosis
• History of clinically significant hypersensitivity associated with monoclonal antibody therapies or components of the emicizumab injection

Laborértékek

• Known HIV infection with CD4 count <200 cells/µL within 24 weeks before screening. Testing is not required if <35 years of age.
• Concurrent disease, treatment, or abnormality in clinical laboratory tests that could interfere with the conduct of the study, may pose an additional risk, or would, in the opinion of the investigator, preclude the participant's safe participation in and completion of the study

Egyéb

• Use of systemic immunomodulators at enrollment or planned use during the study

• Moderately severe hemophilia A, defined as FVIII level <0.05 IU/mL before development of an inhibitor
• Age ≥6 years of age at time of informed consent
• Documented on 2 occasions a high titer inhibitor (>5 BU/mL) with a 72-hour washout within 2 years of enrollment
• Parent/guardian (Legally Authorized Representative) or the patient has provided written informed consent
• Adequate hematologic function (Hgb >8 g/dL and platelet count >100,000 µL)
• Adequate hepatic function (total bilirubin ≤1.5 x ULN and both AST/ALT ≤3x ULN at screening (excluding known Gilbert's)
• Adequate renal function (≤2.5 x ULN and CrCl ≥30 mL/min)
