Important Safety Information

Boxed WARNING: THROMBOTIC MICROANGIOPATHY and THROMBOEMBOLISM

Cases of thrombotic microangiopathy and thrombotic events were reported when on average a cumulative amount of >100 U/kg/24 hours of activated prothrombin complex concentrate (aPCC) was administered for 24 hours or more to patients receiving HEMLIBRA prophylaxis. Monitor for the development of thrombotic microangiopathy and thrombotic events if aPCC is administered. Discontinue aPCC and suspend dosing of HEMLIBRA if symptoms occur.

Warnings and Precautions

• Immunogenicity: Anti-emicizumab antibodies (including neutralizing antibodies) have developed in HEMLIBRA-treated patients
• In case of clinical signs of loss of efficacy, promptly assess the etiology and consider a change in treatment if neutralizing antibodies are suspected
• Laboratory coagulation test interference: HEMLIBRA interferes with activated clotting time (ACT); activated partial thromboplastin time (aPTT); and coagulation laboratory tests based on aPTT, including one-stage, aPTT-based single-factor assays; aPTT-based Activated Protein C Resistance (APC-R); and Bethesda assays (clotting-based) for factor VIII (FVIII) inhibitor titers. Intrinsic pathway clotting-based laboratory tests should not be used
