    Blood Coagulation Factors

    BOXED WARNING

    Disseminated intravascular coagulation (DIC), myocardial infarction, thromboembolic disease

    Anti-inhibitor coagulant complex (AICC) is contraindicated in patients with disseminated intravascular coagulation (DIC) and patients with acute thrombosis or embolism, including myocardial infarction. Thrombotic and thromboembolic disease, including DIC, venous thrombosis, pulmonary embolism, myocardial infarction, and stroke, have been reported following AICC administration. Many of these events occurred after high doses (more than 200 units/kg/day) and/or in patients with thrombotic risk factors. Patients with DIC, advanced atherosclerotic disease, crush injury, septicemia, or concomitant treatment with recombinant factor VIIa have an increased risk of thrombosis due to predisposing coagulopathy or circulating tissue factor. Potential benefit of treatment with AICC should be weighed against risk for thromboembolic event. Monitor patients receiving AICC more than 100 units/kg for signs and symptoms of DIC, acute coronary ischemia, and other thromboembolic events. If signs or symptoms such as chest pain or pressure, shortness of breath, altered consciousness, vision, or speech, limb or abdomen swelling and/or pain occur, discontinue the AICC infusion and initiate appropriate diagnostic and therapeutic measures.

    ADMINISTRATION

    Injectable Administration

    Visually inspect parenteral products for particulate matter and discoloration prior to administration whenever solution and container permit. The solution should be colorless to slightly yellowish. Do not use if particulate matter or discoloration is observed.
     
    Reconstitution
    Use aseptic technique throughout the entire reconstitution process. Allow concentrate and diluent vials to reach room temperature.
    Remove caps from both vials. Wipe the rubber stoppers with a sterile alcohol swab and allow it to dry.
    Peel away lid of BAXJECT II Hi-Flow device taking care not to touch the inside. Do not remove the device from the package. Do not touch the clear spike.
    Turn the package over and insert the clear plastic spike through diluent stopper by pressing straight down. Grip the device package at the edges and pull the package off the device. Do not remove the blue protective cap from the device. Do not touch the purple spike.
    Turn the system over, so that the diluent vial is on top. Quickly insert the purple spike of the device fully into the concentrate vial. The vacuum will draw the diluent into the vial. The connection of the 2 vials should be done quickly to close the open fluid pathway created by the first insertion of the spike to the diluent vial.
    Gently swirl until completely dissolved. If not dissolved completely, active material will not pass through the device filter. Do not shake.
    Storage: Administer within 3 hours of reconstitution. Do not refrigerate after reconstitution.

    Intravenous Administration

    Flush venous access lines with isotonic saline prior to and after infusion. Do not administer in the same tubing or container with other medicinal products.
    Use plastic luer-lock syringes. Protein such as anti-inhibitor coagulant complex tends to stick to the surface of all-glass syringes.
    Remove the blue protective cap from the BAXJECT II Hi-Flow device. Tightly connect the syringe to the device by turning the syringe in clockwise direction until stop position.
    Invert the system so that the dissolved concentrate product is on top and draw the dissolved product into the syringe by pulling the plunger back slowly to avoid foaming. Ensure the tight connection between the device and syringe is maintained.
    Disconnect the syringe.
    Attach a suitable needle and inject or infuse intravenously at a rate not to exceed 2 units/kg/minute.

    CONTRAINDICATIONS / PRECAUTIONS

    General Information

    Anti-inhibitor coagulant complex is contraindicated in patients with known anaphylactic or severe hypersensitivity reactions to anti-inhibitor coagulant complex or any of its components, including factors of the kinin generating system.

    Disseminated intravascular coagulation (DIC), myocardial infarction, thromboembolic disease

    Anti-inhibitor coagulant complex (AICC) is contraindicated in patients with disseminated intravascular coagulation (DIC) and patients with acute thrombosis or embolism, including myocardial infarction. Thrombotic and thromboembolic disease, including DIC, venous thrombosis, pulmonary embolism, myocardial infarction, and stroke, have been reported following AICC administration. Many of these events occurred after high doses (more than 200 units/kg/day) and/or in patients with thrombotic risk factors. Patients with DIC, advanced atherosclerotic disease, crush injury, septicemia, or concomitant treatment with recombinant factor VIIa have an increased risk of thrombosis due to predisposing coagulopathy or circulating tissue factor. Potential benefit of treatment with AICC should be weighed against risk for thromboembolic event. Monitor patients receiving AICC more than 100 units/kg for signs and symptoms of DIC, acute coronary ischemia, and other thromboembolic events. If signs or symptoms such as chest pain or pressure, shortness of breath, altered consciousness, vision, or speech, limb or abdomen swelling and/or pain occur, discontinue the AICC infusion and initiate appropriate diagnostic and therapeutic measures.

    Viral infection

    Anti-inhibitor coagulant complex (AICC) is derived from human plasma and may therefore carry a risk of transmitting viral infection, and theoretically, the Creutzfeldt-Jakob disease agent. Screening plasma donors for prior exposure to certain viruses, testing for the presence of viruses, and inactivating and/or reducing viruses has reduced the risk of transmission of infectious agents; however, none of the processes are completely effective. All infections thought to have been transmitted by AICC should be reported to the manufacturer and/or the FDA (1-800-FDA-1088 or www.fda.gov/medwatch).

    Thrombocytopenia

    An inadequate response to anti-inhibitor coagulant complex (AICC) may be seen in patients with thrombocytopenia or abnormal platelet function which were present prior to treatment with AICC.

    Pregnancy

    Anti-inhibitor coagulant complex (AICC) is considered a FDA pregnancy category C agent. There are no data regarding whether AICC may cause fetal harm or affect reproduction capacity. AICC should only be used in pregnancy if clearly needed.

    Breast-feeding

    Information from the manufacturer is not available as to whether anti-inhibitor coagulant complex (AICC) is excreted in breast milk. Because many drugs are excreted in breast milk and the potential for serious adverse reaction in nursing infants, a decision should be made whether to discontinue breast-feeding or to discontinue AICC considering the importance of the drug to the mother. Consider the benefits of breast-feeding, the risk of potential infant drug exposure, and the risk of an untreated or inadequately treated condition. If a breast-feeding infant experiences an adverse effect related to a maternally ingested drug, healthcare providers are encouraged to report the adverse effect to the FDA.

    Children

    In some cases, laboratory tests such as activated thromboplastin time (aPTT) may not correlate with clinical response of anti-inhibitor complex (AICC) treatment. Hemostatic improvement may occur without a reduction in aPTT. However, a shortened prothrombin time (PT) would be expected. Attempts to normalize these parameters by increasing the doses of AICC is not recommended due to the increased risk of disseminated intravascular coagulation (DIC) associated with increased doses. In children, fibrinogen levels should be determined prior to and monitored during AICC treatment.

    Tranexamic Acid: (Major) Use of tranexamic acid within approximately 6 to 12 hours after the administration of anti-inhibitor coagulant complex (human) is not recommended, due to the increased risk of thrombosis.

    PREGNANCY AND LACTATION

    Pregnancy

    Anti-inhibitor coagulant complex (AICC) is considered a FDA pregnancy category C agent. There are no data regarding whether AICC may cause fetal harm or affect reproduction capacity. AICC should only be used in pregnancy if clearly needed.

    Information from the manufacturer is not available as to whether anti-inhibitor coagulant complex (AICC) is excreted in breast milk. Because many drugs are excreted in breast milk and the potential for serious adverse reaction in nursing infants, a decision should be made whether to discontinue breast-feeding or to discontinue AICC considering the importance of the drug to the mother. Consider the benefits of breast-feeding, the risk of potential infant drug exposure, and the risk of an untreated or inadequately treated condition. If a breast-feeding infant experiences an adverse effect related to a maternally ingested drug, healthcare providers are encouraged to report the adverse effect to the FDA.

    MECHANISM OF ACTION

    Anti-inhibitor coagulant complex (AICC) provides activated coagulation factors to restore hemostasis in patients with inhibitors to certain coagulation factors. The actual active component of AICC has not been identified and may include activated factor VII, activated factor X with or without phospholipid or a combination of factors. Anti-inhibitor coagulant complex may induce a hypercoagulable state leading thrombosis or disseminated intravascular coagulation due to the administration of activated factors, presence of circulating tissue factor and the underlying coagulopathy. Administration of AICC results in changes in coagulation parameters, most notably prothrombin time (PT); however, the degree of change may not reflect the actual clinical effect.

    PHARMACOKINETICS

    Anti-inhibitor coagulant complex (AICC) is administered intravenously. The onset of activity is dependent upon the amount of activated factor present, type of inhibitor present, and the half-lives of the factors. The half-lives of the factors present in AICC are as follows: factor II, more than 60 hours; factor VII, 4 to 6 hours; factor IX, 20 to 24 hours; and factor X, 48 to 72 hours.
