ADYNOVATE [Antihemophilic Factor (Recombinant), PEGylated] Lyophilized Powder for Solution For Intravenous Injection Brief Summary of Prescribing Information: Please see package insert for full Prescribing Information. INDICATIONS AND USAGE Table 1: Adverse Reactions Reported for ADYNOVATE ADYNOVATE, Antihemophilic Factor (Recombinant), PEGylated, is a human antihemophilic factor indicated in adolescent and adult patients (12 years and older) with hemophilia A (congenital factor VIII deficiency) for: • On-demand treatment and control of bleeding episodes MedDRA Preferred Term Number of Subjects n (%) (N=169) Percent per Infusion (N = 13579) Diarrhea 1 (0.6%) 0.01% Nausea 2 (1.2%) 0.01% Nervous System Disorders Headache 5 (3.0%) 0.06% Vascular Disorders Flushing 1 (0.6%) 0.01% MedDRA System Organ Class Gastrointestinal Disorders • Routine prophylaxis to reduce the frequency of bleeding episodes ADYNOVATE is not indicated for the treatment of von Willebrand disease. CONTRAINDICATIONS ADYNOVATE is contraindicated in patients who have had prior anaphylactic reaction to ADYNOVATE, to the parent molecule (ADVATE [Antihemophilic factor (Recombinant)]), mouse or hamster protein, or excipients of ADYNOVATE (e.g. Tris, mannitol, trehalose, glutathione, and/or polysorbate 80). WARNINGS AND PRECAUTIONS Hypersensitivity Reactions Hypersensitivity reactions are possible with ADYNOVATE. Allergic-type hypersensitivity reactions, including anaphylaxis, have been reported with other recombinant antihemophilic factor VIII products, including the parent molecule, ADVATE. Early signs of hypersensitivity reactions that can progress to anaphylaxis may include angioedema, chest tightness, dyspnea, wheezing, urticaria, and pruritus. Immediately discontinue administration and initiate appropriate treatment if hypersensitivity reactions occur. Neutralizing Antibodies Formation of neutralizing antibodies (inhibitors) to factor VIII can occur following administration of ADYNOVATE. Monitor patients regularly for the development of factor VIII inhibitors by appropriate clinical observations and laboratory tests. Perform an assay that measures factor VIII inhibitor concentration if the plasma factor VIII level fails to increase as expected, or if bleeding is not controlled with expected dose. Monitoring Laboratory Tests • Monitor plasma factor VIII activity by performing a validated onestage clotting assay to confirm the adequate factor VIII levels have been achieved and maintained. • Monitor for the development of factor VIII inhibitors. Perform the Bethesda inhibitor assay to determine if factor VIII inhibitor is present. If expected factor VIII activity plasma levels are not attained, or if bleeding is not controlled with the expected dose of ADYNOVATE, use Bethesda Units (BU) to determine inhibitor le
