    Intravenous dosage (Humate-P)

    Adults

    For emergency surgery, give a loading dose of 50 to 60 International Units/kg IV, and monitor the patient's trough coagulation factor concentrations. For all planned surgeries, calculate a loading dose to give 1 to 2 hours before surgery using the patient's individual in vivo recovery (IVR). To determine the IVR prior to procedure, if possible, measure the baseline plasma vWF:RCo; infuse 60 International Units vWF:RCo/kg IV at time 0, and measure plasma vWF:RCo at time 30 minutes. The IVR is calculated by using the formula: IVR = (Plasma vWF:RCo30 min - Plasma vWF:RCo baseline) / 60 International Units kg. If the IVR is unavailable, assume an IVR of 2 International Units/dL per International Units/kg. The loading dose is calculated using the formula: Loading dose = [(Target vWF:RCo - Baseline vWF:RCo) x Weight] / IVR. For minor surgery: The vWF:RCo target peak plasma concentration is 50 to 60 International Units/dL, and the FVIII:C target peak plasma concentration is 40 to 50 International Units/dL. After achievement of the FVIII:C target concentration, the initial maintenance dose is half of the loading dose. The vWF:RCo target trough plasma concentration is 30 International Units/dL or more for the first 3 days after surgery, and the FVIII:C target trough plasma concentration after day 3 is more than 30 International Units/dL. The minimum treatment duration is 48 hours. For major surgery: The vWF:RCo target peak plasma concentration is 100 International Units/dL and the FVIII:C target peak plasma concentration is 80 to 100 International Units/dL. After achievement of the FVIII:C target concentration, the initial maintenance dose is half of the loading dose. The vWF:RCo and FVIII:C target trough plasma concentrations are greater than 50 International Units/dL for the first 3 days after surgery and greater than 30 International Units/dL after day 3. The minimum treatment duration is 72 hours. For oral surgery: For removal of less than 3 non-molar teeth with no bony involvement, the minimum treatment duration is 8 to 12 hours with at least 1 maintenance dose after surgery based on individual pharmacokinetic values. Removal of more than 1 impacted wisdom tooth is considered major surgery, especially in patients with type 2A or type 3 vWD. Removal of more than 2 teeth is considered major surgery in all patients. Maintenance dose: Frequency is usually every 8 to 12 hours and is determined based on individual pharmacokinetic-derived half-lives. If pharmacokinetic data are unavailable, give Humate-P every 8 hours; monitor trough coagulation factor concentrations to determine any needed adjustments. Monitor trough vWF:RCo and FVIII:C concentrations at least once daily. Consider administration interval and/or dose adjustment for insufficient hemostatic levels or trough concentrations that are outside the recommended range. Because the ratio of vWF:RCo to FVIII:C activity in Humate-P is 2.4 to 1, any additional dosing will increase vWF:RCo proportionally more than FVIII:C. Assuming an incremental IVR of 2 International Units vWF:RCo/dLper International Units/kg infused, additional dosing to increase FVIII:C in plasma will also increase plasma vWF:RCo by approximately 5 International Units/dL for each International Units/kg of FVIII administered. Do not exceed a trough concentration of 100 International Units/dL for either coagulation factor.[56306]

    Infants, Children, and Adolescents

    For emergency surgery, give a loading dose of 50 to 60 International Units/kg IV, and monitor the patient's trough coagulation factor concentrations. For all planned surgeries, calculate a loading dose to give 1 to 2 hours before surgery using the patient's individual in vivo recovery (IVR). To determine the IVR prior to procedure, if possible, measure the baseline plasma vWF:RCo; infuse 60 International Units vWF:RCo/kg IV at time 0, and measure plasma vWF:RCo at time 30 minutes. The IVR is calculated by using the formula: IVR = (Plasma vWF:RCo30 min - Plasma vWF:RCobaseline) / 60 International Units kg. If the IVR is unavailable, assume an IVR of 2 International Units/dL per International Units/kg. The loading dose is calculated using the formula: Loading dose = [(Target vWF:RCo - Baseline vWF:RCo) x Weight] / IVR. For minor surgery: The vWF:RCo target peak plasma concentration is 50 to 60 International Units/dL, and the FVIII:C target peak plasma concentration is 40 to 50 International Units/dL. After achievement of the FVIII:C target concentration, the initial maintenance dose is half of the loading dose. The vWF:RCo target trough plasma concentration is 30 International Units/dL or more for the first 3 days after surgery, and the FVIII:C target trough plasma concentration after day 3 is more than 30 International Units/dL. The minimum treatment duration is 48 hours. For major surgery: The vWF:RCo target peak plasma concentration is 100 International Units/dL and the FVIII:C target peak plasma concentration is 80 to 100 International Units/dL. After achievement of the FVIII:C target concentration, the initial maintenance dose is half of the loading dose. The vWF:RCo and FVIII:C target trough plasma concentrations are greater than 50 International Units/dL for the first 3 days after surgery and greater than 30 International Units/dL after day 3. The minimum treatment duration is 72 hours. For oral surgery: For removal of less than 3 non-molar teeth with no bony involvement, the minimum treatment duration is 8 to 12 hours with at least 1 maintenance dose after surgery based on individual pharmacokinetic values. Removal of more than 1 impacted wisdom tooth is considered major surgery, especially in patients with type 2A or type 3 vWD. Removal of more than 2 teeth is considered major surgery in all patients. Maintenance dose: Frequency is usually every 8 to 12 hours and is determined based on individual pharmacokinetic-derived half-lives. If pharmacokinetic data are unavailable, give Humate-P every 8 hours; monitor trough coagulation factor concentrations to determine any needed adjustments. Monitor trough vWF:RCo and FVIII:C concentrations at least once daily. Consider administration interval and/or dose adjustment for insufficient hemostatic levels or trough concentrations that are outside of the recommended range. Because the ratio of vWF:RCo to FVIII:C activity in Humate-P is 2.4 to 1, any additional dosing will increase vWF:RCo proportionally more than FVIII:C. Assuming an incremental IVR of 2 International Units vWF:RCo/dL per International Units/kg infused, additional dosing to increase FVIII:C in plasma will also increase plasma vWF:RCo by approximately 5 International Units/dL for each International Units/kg of FVIII administered. Do not exceed a trough concentration of 100 International Units/dL for either coagulation factor.[56306]

    Intravenous dosage (Wilate)

    Adults

    Calculate a loading dose to give within 3 hours before surgery using the patient's individual in vivo recovery (IVR). To determine the IVR prior to procedure, if possible, measure the baseline plasma vWF:RCo; infuse 60 International Units vWF:RCo/kg IV at time 0, and measure plasma vWF:RCo at time 30 minutes. The IVR is calculated by using the formula: IVR = (Plasma vWF:RCo30min - Plasma vWF:RCobaseline) / 60 International Units kg. If the actual IVR exceeds 2.5, use 2.5 to calculate the loading dose to avoid under dosing. If the IVR is unavailable, assume an IVR of 2 International Units/dL per International Units/kg. The loading dose is calculated using the formula: Loading dose = [(Target vWF:RCo - Baseline vWF:RCo) x Weight] / IVR. Alternately, the following regimens by surgery type provide a dosing range that is expected to provide the desired peak vWF:RCo concentrations. For minor surgery (including tooth extractions): 30 to 60 International Units/kg IV loading dose given within 3 hours before surgery followed by a maintenance dose of 15 to 30 International Units/kg, or one-half the loading dose, every 12 to 24 hours until wound healing is achieved, up to 3 days. The target vWF:RCo peak plasma concentration is 50% of normal with a trough concentration of more than 30% of normal during maintenance doses. For major surgery: 40 to 60 International Units/kg IV loading dose given within 3 hours before surgery followed by a maintenance dose of 20 to 40 International Units/kg, or one-half the loading dose, every 12 to 24 hours until wound healing is achieved, up to at least 6 days. At least 2 doses should be administered within the first 24 hours after surgery. The target vWF:RCo peak plasma concentration is 100% of normal with a trough concentration of more than 50% of normal during maintenance doses. If possible, measure appropriate laboratory tests daily after surgery to ensure adequate vWF:RCo and factor VIII activity concentrations are maintained. To decrease the risk of perioperative thrombosis, factor VIII activity concentrations should not exceed 250% of normal.[56305]

    Infants, Children, and Adolescents

    Calculate a loading dose to give within 3 hours before surgery using the patient's individual in vivo recovery (IVR). To determine the IVR prior to procedure, if possible, measure the baseline plasma vWF:RCo; infuse 60 International Units vWF:RCo/kg IV at time 0, and measure plasma vWF:RCo at time 30 minutes. The IVR is calculated by using the formula: IVR = (Plasma vWF:RCo30 min - Plasma vWF:RCobaseline) / 60 International Units kg. If the actual IVR exceeds 2.5, use 2.5 to calculate the loading dose to avoid under dosing. If the IVR is unavailable, assume an IVR of 2 International Units/dL per International Units/kg. The loading dose is calculated using the formula: Loading dose = [(Target vWF:RCo - Baseline vWF:RCo) x Weight] / IVR. Alternately, the following regimens by surgery type provide a dosing range that is expected to provide the desired peak vWF:RCo concentrations. For minor surgery (including tooth extractions): 30 to 60 International Units/kg IV loading dose given within 3 hours before surgery followed by a maintenance dose of 15 to 30 International Units/kg, or one-half the loading dose, every 12 to 24 hours until wound healing is achieved, up to 3 days. The target vWF:RCo peak plasma concentration is 50% of normal with a trough concentration of more than 30% of normal during maintenance doses. For major surgery: 40 to 60 International Units/kg IV loading dose given within 3 hours before surgery followed by a maintenance dose of 20 to 40 International Units/kg, or one-half the loading dose, every 12 to 24 hours until wound healing is achieved, up to at least 6 days. At least 2 doses should be administered within the first 24 hours after surgery. The target vWF:RCo peak plasma concentration is 100% of normal with a trough concentration of more than 50% of normal during maintenance doses. If possible, measure appropriate laboratory tests daily after surgery to ensure adequate vWF:RCo and factor VIII activity concentrations are maintained. To decrease the risk of perioperative thrombosis, factor VIII activity concentrations should not exceed 250% of normal.[56305]

    Therapeutic Drug Monitoring

    • Monitor plasma factor VIII activity by performing a validated one-stage clotting or chromogenic assay to confirm adequate concentrations of factor VIII have been achieved and maintained.[56305] [56332] [60830] [61730]
      • Monitor factor VIII activity 15 to 30 minutes and 3 hours after the initial dose.
      • Monitor factor VIII activity 15 to 30 minutes after subsequent doses.[55323] [58255]
    • One-stage clotting assay results can be affected by the type of aPTT reagent used. Some silica-based aPTT reagents underestimate the activity of factor VIII by up to 60%; other reagents including those with kaolin-based activators may overestimate activity by 20%. If an appropriate one-stage clotting or chromogenic assay is not available locally, use a reference laboratory.[60830] [63486] [63978]
    • In patients with von Willebrand's disease (vWD), monitor trough plasma vWF:RCo and factor VIII activities at least once daily. Sustained excessive vWF and factor VIII activity concentrations increase the risk of thrombotic events.[56305] [56306] [56307] Guidelines recommend not exceeding vWF:RCo concentrations of 200 International Units/dL and factor VIII concentrations of 250 to 300 International Units/dL.[64325]
    • Monitor for the development of factor VIII inhibitors, and vWF inhibitors if applicable.
    • Perform a Nijmegen-modified Bethesda assay to determine whether factor VIII inhibitors are present. Use Bethesda Units (BU) to report inhibitor concentrations.[55323] [56305] [56332] [60830] [61730]
      • An inhibitor titer of 0.6 BU/mL or more is considered clinically significant.
      • A low-responding inhibitor is defined by a concentration persistently less than 5 BU/mL.
      • A high-responding inhibitor id defined by a concentration of 5 BU/mL or more.[55323]
    • Assays for detecting vWF inhibitors are not as well-established.[64325]

      Description/Classification

      Description

      Antihemophilic factor (AHF), also known as factor VIII, is a parenteral coagulation factor indicated for perioperative management and prophylactic or on-demand treatment of bleeding in people with hemophilia A or von Willebrand's disease (vWD).[56305] [56306] Factor VIII concentrates are the treatment of choice for hemophilia A.[55323] Plasma-derived von Willebrand factor (vWF)-containing factor VIII concentrates are used in certain types of vWD that do not respond to desmopressin, as well as in surgical situations.[64333] Reduction in vWF results in a correspondingly low factor VIII activity, making replacement of both important in vWD.[64325] Both plasma-derived and recombinant concentrates are suitable for the management of bleeding disorders; screening plasma donors, testing for viral presence, viral inactivation and/or reduction have improved the safety of plasma-derived products. The development of factor replacement products with prolonged half-lives improves patient adherence by enabling less frequent infusions, decreasing the bleeding rate, and reducing the burden of treatment.[62144] Several technologies have been applied to extend the half-life of factor VIII, including the addition of polyethylene glycol (PEG) to factor VIII.[60296] [63486] [63978] The most serious iatrogenic complication of hemophilia treatment is the development of factor inhibitors, which causes neutralization of the infused factor. Inhibitors are more common in hemophilia A, developing in up to 30% of patients. In comparison, the incidence in those with hemophilia B is approximately 5%.[64334] In patients with vWD, an excessive rise in factor VIII activity may increase the risk of thromboembolism. Assess each patient's risk of thrombosis, monitor plasma vWF:RCo and factor VIII activities, and institute appropriate antithrombotic measures in patients receiving coagulation factor replacement therapy as necessary.[64325]

      Continuous intravenous infusion

      NOTE: Antihemophilic Factor, AHF, Factor VIII is not FDA-approved for continuous intravenous infusion.

      • Infuse using a controlled infusion device.
      • The following factor VIII agents have been shown to maintain activity more than 80% above baseline in a polypropylene container at 20 to 23 degrees C for at least 24 hours: Hemofil M, Humate-P, Monoclate-P, and Recombinate.[24463]
      • Many of the high-purity or recombinant factor formulations have demonstrated stability when administered via continuous infusion for at least 1 to 3 days. The factors should be reconstituted as directed by the manufacturer and not further diluted as they may not be stable if further diluted. One study indicates that when factor VIII (Kogenate) was infused through polyethylene tubing, a decrease in activity was apparent for the first 5 mL most likely due to adsorption of the concentrate to the tubing. In contrast, a decrease in activity was not apparent when infused through polyvinyl chloride tubing.[32320] [32321]

      Stability
      Antihemophilic factor VIII injection in intact containers stored as directed by the manufacturer is stable until the labeled expiration date. Intact containers may be stored up to three months at controlled room temperature up to 25 degree C for Kogenate FS and Refacto and up to 30 degree C for Recombinate. The manufacturers recommend use of the reconstituted solutions within 3 hours of preparation because no antimicrobial preservative is present. The reconstituted solution should not be refrigerated. Parti et al. reported that antihemophilic factor VIII (ADVATE) reconstituted as directed was stable for 24 hours with about 92% activity remaining when stored at controlled room temperature. Fernandez et al. evaluated the stability of antihemophilic factor VIII (recombinant) (ADVATE) diluted in normal saline or dextrose and saline solutions that were exposed to ultraviolet and visible light for 10 hours. The authors reported that the factor VIII was stable under conditions similar to those encountered during continuous infusion. NOTE: Also see Sorption.

      Light Exposure
      The manufacturer of Kogenate FS states that the product should be protected from extreme exposure to light during long-term storage. Parti et al. reported discoloration and loss of approximately 30% concentration of reconstituted antihemophilic factor VIII with exposure for 10 hours to natural daylight at about 25 degree C. Under the same conditions, no such loss occurred in the intact unreconstituted lyophilized dosage form. Fernandez et al. evaluated the stability of antihemophilic factor VIII (recombinant) (ADVATE) diluted in normal saline or dextrose and saline solutions were exposed to ultraviolet and visible light for 10 hours. The authors reported that the factor VIII was stable under conditions similar to those encountered during continuous infusion.

      Filtration
      Use the filter needle provided to withdraw the drug from the vial during preparation. Sakazume et al. reported on antihemophilic factor VIII (recombinant) from Bayer at a concentration of 1 unit in sodium chloride 0.9% delivered at 1 mL/minute through a polyvinyl chloride (PVC) administration set with two types of 0.2-micron inline filters. No added loss of drug occurred when using a polysulfone filter, but about 35 to 45% loss to the filters occurred when using polyethersulfone filters.

      Sorption Leaching
      Sorption: Antihemophilic factor VIII (recombinant) may undergo loss due to sorption to some plastic administration equipment. However, the available information is by no means definitive or even consistent. There have been many conflicting studies that are confusing and make a simple resolution on which container materials and delivery equipment to use difficult. McLeod et al. evaluated the stability of antihemophilic factor VIII (recombinant) (Kogenate, Bayer) reconstituted to a concentration of 146 units/mL and diluted to concentrations of 10 and 2 units/mL in 100-mL sodium chloride 0.9% in polyvinyl chloride (PVC) bags (Viaflex, Baxter). After storage at room temperature for 48 hours, Western blot analyses found losses of nearly 60% in the more concentrated solutions of 146 and 10 units/mL and about 98% loss from the 2-units/mL solution. Much of the lost factor VIII was able to be recovered by elution of the empty PVC bags. In contrast, the same solutions packaged in polypropylene plastic syringes (Becton Dickinson) stored for 48 hour at room temperature exhibited no loss of factor VIII. The authors suggested using polypropylene syringes and syringe drivers to administer the drug. Schulman, Gitel et al. evaluated the stability of 15 different antihemophilic factor VIII concentrates stored at 4 to 8, 20 to 23, and 37 degree C for up to four weeks. The samples were packaged in original glass containers and polypropylene tubes but NOT in infusion bags. The authors reported the factor VIII concentrates to be stable refrigerated and at room temperature for several days. Schulman, Varon et al. evaluated the completeness of delivery of reconstituted antihemophilic factor VIII concentrate (Monoclate-P) using minipump infusion systems. The concentration of the factor VIII decreased to below 80% of the initial amount after storage for three days in a CADD-1 pump. Acceptable concentrations were maintained using an Infumed minipump for up to seven days. Hurst et al. reported contradictory information in an evaluation of the stability of reconstituted antihemophilic factor VIII (recombinant) (Kogenate, Bayer) concentrate under refrigeration at 5 degree C and at room temperature of 25 to 30 degree C. They found a 10-fold greater loss of factor VIII from the initial delivered solution with polyethylene administration equipment compared to PVC. However, the concentration soon returned to the initial concentration and remained stable for seven days. DiMichelle et al. evaluated the stability of antihemophilic factor VIII (recombinant) 10 units/mL diluted in PVC bags of sodium chloride 0.9% and delivered through administration lines. An initial loss to 57 to 76% of the initial concentration occurred with a gradual return of concentration after about two hours. Addition of human albumin to the samples did not reduce the loss. This result is at variance with the report of McLeod et al. above who reported substantial losses with no recovery. Sakazume et al. evaluated antihemophilic factor VIII (recombinant) (Kogenate, Bayer) at a concentration of 1 unit/mL in sodium chloride 0.9% delivered at 1 mL/minute through PVC and also polybutadiene plastic administration tubing. Drug losses of 10 to 16% occurred with the PVC tubing, but no loss occurred with the polybutadiene tubing. Fernandez et al. evaluated the delivery of antihemophilic factor VIII (recombinant) (ADVATE) using several delivery devices. The report stated that at least 95% of the factor VIII was delivered over 48 hours when using a multi-therapy 6060 pump system (Baxter) for administration. Similarly, using Medex or Harvard syringe pumps or a CADD pump-1 delivery was 83% or greater over 24 or 48 hours. The authors concluded continuous infusion of antihemophilic factor VIII with these devices was safe and effective. Belgaumi et al. evaluated the stability and delivery of antihemophilic factor VIII (Bioclate) 50, 100, and 250 units/mL with and without heparin and vancomycin delivered by MiniMed 404-SP minipump during simulated administration at temperatures of 21, 37, and 39 degree C over periods up to 28 days. Using a chromagenic assay and Western Blot for purity, the authors reported the concentration, temperature, and the presence or absence of heparin and vancomycin did not affect factor VIII stability. Greater than 75% was delivered in most samples over 3 to 7 days; the 50-unit/mL samples at 21 degree C remained stable for 28 days. (NOTE: 75% is an unusually low concentration to be considered "stable.") The use of plastic syringes for handling antihemophilic factor VIII (recombinant) has been suggested because proteins tend to adhere more to glass syringes than to plastic syringes. However, see McLeod et al. above who reported no loss of antihemophilic factor VIII (recombinant) from solution to polypropylene syringes during storage for 48 hours. Leaching: Polysorbate 80, a surfactant known to leach diethylhexyl phthalate plasticizer from polyvinyl chloride (PVC) infusion solution bags and sets, is a component of the formulation of antihemophilic factor VIII (recombinant). However, the surfactant is present in small quantity and substantial leaching of plasticizer is not likely to occur.

      Microbial Contamination: Belgaumi et al. evaluated antihemophilic factor VIII (Bioclate) 50, 100, and 250 units/mL with and without heparin and vancomycin delivered by MiniMed 404-SP minipump during simulated administration at temperatures of 21, 37, and 39 degree C over periods up to 28 days. Inoculation of samples with several common bacteria showed rapid growth over three days. The presence of vancomycin caused a modest suppression of Staphylococcus aureus but not Escherichia coli. The authors noted that bacterial contamination could result in systemic infection.

        Adverse reactions to antihemophilic factor, AHF, factor VIII are usually related to the injection or are allergic reactions. Infusion-related reactions (0.5%) and/or injection site reaction including pain and inflammation (0.4% to 6.6%), extravasation (2.5%), hematoma (2.5%), device-related problems (4.2%), redness (1.9%), face edema (more than 5%), fever (0.4% or more), chest pain (unspecified)/chest discomfort (1%), feeling hot (0.4%), urticaria (0.5% or more), pruritus (0.3% or more), rash (0.3% or more), erythema (0.4%), chills (0.4% or more), hyperhidrosis (0.5%), and anaphylactoid reactions (0.5%) have been reported in patients receiving antihemophilic factor, AHF, factor VIII. Hypersensitivity has been reported in 0.3% to 6% of patients and includes urticaria, chest tightness, rash, pruritus, and edema. Allergic dermatitis (0.8%), ocular hyperemia (0.8%), and eosinophilia (0.5%) have also been reported and may be related to hypersensitivity. Angioedema, erythema, and anaphylactoid reactions, including anaphylactic shock, have been reported with postmarketing use of antihemophilic factor, AHF, factor VIII.[56302] [56305] [56306] [56307] [56325] [56329] [56332] [60156] [60296] [60650] [60830] [63978]

        Rarely, after large doses of antihemophilic factor, AHF, Factor VIII acute hemolytic anemia, increased bleeding tendency, or hyperfibrinogenemia have been reported. Certain AHF products (Alphanate, Humate-P, Koate-HP, and Koate-DVI) in large and/or frequent doses in patients with A, B, or AB blood types may result in intravascular hemolysis and hemolytic anemia. Should this occur, consider the administration of serologically compatible type O red blood cells or the administration of AHF produced from group-specific plasma.[56306] [56307]

        Mild thrombocytopenia has been reported with the use of porcine antihemophilic factor, AHF, factor VIII. Thrombocytopenia is usually mild and does not appear to affect the patients overall hemostasis. Severity and incidence of platelet effect does not appear to be dose-related and may be due to the presence of porcine von Willebrand factor. Pseudothrombocytopenia (platelet clumping leading to a false low reading) has been reported in a single patient receiving antihemophilic factor/von Willebrand factor complex.[56306] Additionally, lymphadenopathy (0.8%) has been reported during clinical trials of antihemophilic factor, AHF, factor VIII.[60650]

        All plasma-derived, human antihemophilic factor, AHF, factor VIII products carry the possibility of causing iatrogenic infection via bloodborne pathogens. The risk of infection associated with plasma-derived AHF products is low due to the careful screening of plasma donors and manufacturing processes, which includes heat-inactivation, solvent detergent viral inactivation process, and monoclonal antibody purification that effectively removes HIV-1, HIV-2, hepatitis B, and hepatitis C. However, new blood-borne pathogens not controlled by present measures can theoretically emerge at any time.[56306] [56332] Transmission of parvovirus B19, hepatitis, and HIV infection through the use of plasma-derived AHF products has been documented. Infectious adverse reactions reported in patients receiving antihemophilic factor, AHF, factor VIII include upper respiratory tract infection (9% to 22%), lower respiratory tract infection (8.4%), ear infection (0.5% to 5%), varicella (4.2%); respiratory tract infections (upper 49% and lower 24%) and varicella (14%) are also common in pediatric patients.[56320] [56325] [60156]

        Antibody formation (inhibitors) to factor VIII has been reported in 0.5% to 54.8% of hemophilia A patients after exposure to antihemophilic factor, AHF, factor VIII products, with a higher incidence reported in previously untreated patients (PUPs)/minimally treated patients (MTPs).[56320] [53625] [60650] In a clinical trial of PUPs, 24 of 56 patients (42.9%) developed inhibitors with a mean of 14.1 exposure days at the time of first positive inhibitor test; 15 (26.8%) PUPs developed high tighter (5 Bethesda Units [BU] or more) inhibitors.[56302] The presence of inhibitors should be suspected if the patient's plasma factor VIII concentration fails to increase as expected or if bleeding is not controlled after adequate dosing. Administration of high bolus doses or continuous infusions of AHF is usually successful in patients with an inhibitor concentration less than 5 BU/mL and is sometimes successful in patients with inhibitor concentrations of 10 to 20 BU/mL. In some cases, high doses of AHF, rapidly administered, may be able to act in coagulation process before it is neutralized by inhibitors. Patients with inhibitors require close monitoring of the plasma factor VIII concentration to determine the appropriate dose of AHF.[25744] Inhibitors to factor VIII are immunoglobulins of the IgG heavy chain class. Light chains of factor VIII inhibitors are solely kappa (most common), solely lambda, or both. The reaction between factor VIII and factor VIII inhibitors seems to be time-dependent and leads to the production of 2 types of inhibitors, Type I and Type II. Type I or simple inhibitors have second-order kinetics where the amount of antibody is related linearly to the residual factor VIII after incubation of factor VIII and inhibitor plasma. Type II inhibitors are usually autoantibodies rather than hemophilic alloantibodies. With Type II inhibitors, the interaction between the inhibitor and factor VIII is variable and does not reach a stable endpoint. Some factor VIII may remain measurable, but if more factor VIII is added it may be partially inactivated. This may be due to the partial dissociation of the factor VIII-inhibitor complex. The most common screening test for inhibitors is the activated partial thromboplastin time (aPTT); the clotting time compared to controls is prolonged in the presence of inhibitors. Quantitative assays measure the amount of factor VIII inactivated by patient plasma under certain conditions. An inhibitor unit is defined as the reciprocal of the dilution of patient plasma that neutralized a specific portion of the factor VIII. The most common test of this type is the Bethesda method. Type I inhibitors can be quantified by this method. The quantity of Type II inhibitors can only be approximated.

        The use of factor VIII-containing products in patients with von Willebrand disease (vWD) has been associated with thrombosis and thromboembolism. Monitor factor VIII and vWF:RCo plasma concentrations to avoid sustained excessive vWF and factor VIII activity concentrations (more than 150 International Units/dL). Consider antithrombotic measures in at-risk vWD patients who are receiving coagulation factor replacement therapy.[56305] [56306] [56307] A patient who received a dose of 60 vWF:RCo International Units/kg developed a pulmonary embolism; the FVIII:C concentration achieved in this patient was 290%.[56307] Unexplained transient worsening of preexisting thrombocytosis occurred in 3.6% of patients with hemophilia A receiving vWF-containing factor VIII concentrate for routine prophylaxis during clinical trials.[56305]

        Elevated hepatic enzymes (0.5% to 1.4%), hyperbilirubinemia (0.5%), and benign renal neoplasm (0.5%) have been reported in patients receiving antihemophilic factor, AHF, factor VIII.[56302] [60156] Two cases of acute pancreatitis, with no precipitating cause identified in 1 case, were reported during an extension study of a clinical trial that evaluated 216 patients. Administration of antihemophilic factor, AHF, factor VIII continued and both cases resolved.[60296]

        Central nervous system (CNS) adverse reactions reported in patients receiving antihemophilic factor, AHF, factor VIII in clinical trials include headache (0.8% to 24%), fatigue (0.5% or more), paresthesias (0.4% or more), dizziness (0.5% to 3.4%), syncope (0.5% to 1.7%), drowsiness (0.9%), insomnia (1.1% to 2.1%), malaise (1.1%), deterioration in neurologic function/behavior (0.5% to 1.7%), tremor (0.5%), head injury (2.6%), and injury (2.6%). Seizures have been reported with postmarketing use. CNS adverse reactions, such as dizziness and paresthesias, have also been reported with postmarketing use of antihemophilic factor, AHF, factor VIII as symptoms of allergic or hypersensitivity reactions.[49402] [56305] [56306] [56307] [56332] [60156] [60296] [60650][60830]

        Gastrointestinal (GI) adverse reactions reported in patients receiving antihemophilic factor, AHF, factor VIII in clinical trials include nausea (0.5% to 13%), vomiting (1.5% to 12%), diarrhea (0.4% to 8%), dysgeusia (0.4% to 1.4%), anorexia (0.9%), gastroenteritis (0.5%), abdominal pain (0.5% to 5.3%), abdominal discomfort (1.3%), dyspepsia (1.7%), dental pain/toothache (3.2%), tonsillitis (2.6%), and tooth abscess (2.6%). In pediatric patients 2 to 11 years, abdominal pain (10%) was reported. GI adverse reactions, such as nausea and vomiting, have also been reported with postmarketing use of antihemophilic factor, AHF, factor VIII as symptoms of allergic or hypersensitivity reactions.[49402] [56306] [56320] [56321] [56325] [56332] [60296] [60650]

        Musculoskeletal adverse reactions reported in patients receiving antihemophilic factor, AHF, factor VIII in clinical trials include arthralgia (5.3% to 23%), back pain (3.7%), extremity pain (3.7% in adults and 10% in children), joint pain (more than 5%), pain (0.5% or more), asthenia (1.4% to 6%), muscle weakness (0.5%), and myalgia (0.5%).[49402] [56307] [56325] [56329]

        Cardiovascular (CV) and vascular adverse reactions reported in patients receiving antihemophilic factor, AHF, factor VIII in clinical trials include orthostatic hypotension (2.6%), peripheral vasodilation (1.4% to 2.3%), thrombo-phlebitis (1.5%), peripheral edema (1.4%), flushing (0.3% to 1%), angina (0.5%), sinus tachycardia (0.5% to 0.8%), hypotension (0.5%), palpitations (0.8%), and pallor (0.5%). Cyanosis, bradycardia, and cardiopulmonary arrest have been reported with postmarketing use. CV adverse reactions, such as tachycardia, chest tightness, hypotension, and flushing, have also been reported with postmarketing use of antihemophilic factor, AHF, factor VIII as symptoms of allergic or hypersensitivity reactions.[56306] [56307] [56321] [56325] [56329] [56332] [60296] [60650]

        Contraindications/Precautions

        Absolute contraindications are italicized.

        • bovine protein hypersensitivity
        • hamster protein hypersensitivity
        • mannitol hypersensitivity
        • murine protein hypersensitivity
        • polysorbate 80 hypersensitivity
        • anemia
        • breast-feeding
        • cardiac disease
        • factor VIII inhibitors
        • hepatitis
        • human immunodeficiency virus (HIV) infection
        • infection
        • latex hypersensitivity
        • pregnancy
        • thromboembolic disease
        • viral infection

        There are no adequate and well-controlled studies using antihemophilic factor, AHF, factor VIII in pregnancy to determine whether there is a drug-associated risk as hemophilia mainly affects males. Animal reproduction studies have not been conducted.[49402] [56302] [60830] [63978]

        There are no data describing the presence of antihemophilic factor, AHF, factor VIII in breast milk, the effect on the breast-fed infant, or the effect on milk production. Consider the developmental and health benefits of breast-feeding along with the mother's clinical need for AHF and any potential adverse effects on the breast-fed infant from AHF or the mother's underlying condition.[56302] [60830] [63978]

        Thrombosis and thromboembolism have been reported in patients with von Willebrand Disease receiving antihemophilic factor/von Willebrand factor complex replacement therapy, especially in patients with known risk factors for thromboembolic disease (e.g., pregnancy, certain thrombophilias). Early reports indicate that the incidence may be higher in females. High concentrations of endogenous Factor VIII have also been associated with thrombosis, although a causal relationship has not yet been established. Caution is advised when administering antihemophilic factor to patients with risk factors for thrombosis and/or thromboembolic disease; antithrombotic measures should be considered.

        As with other products derived from or purified with human blood components, the possibility of contamination with hepatitis and other viral or bacterial infections exists in patients receiving plasma-derived antihemophilic factor products (i.e., Alphanate, Hemofil M, Humate-P, Koate-HP, Koate-DVI, Monarc-M, Monoclate-P, and Wilate). 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. The manufacturing processes are designed to reduce the risk of transmitting viral infection; however, none of the processes are completely effective. There is also the possibility that unknown infectious agents may be present in these products. It is recommended that all patients with hemophilia receive vaccination against hepatitis A and B at birth or at diagnosis of hemophilia.

        Certain brands of antihemophilic factor, specifically Alphanate, Humate-P, Koate-HP, contain small amounts of isoagglutinins for blood groups A and B. Caution and frequent monitoring (hematocrit and Coombs' test) is advised when giving large or frequently repeated doses to patients with blood groups A, B, and AB due to the possibility of developing anemia and intravascular hemolysis.

        Antihemophilic factor, AHF, factor VIII is contraindicated in patients who have had life-threatening hypersensitivity reactions to any constituents of the product.[56366] Monoclonal antibody-purified and recombinant antihemophilic factor products contain varying amounts of animal protein and should be used with caution in patients with bovine protein hypersensitivity, hamster protein hypersensitivity, and murine protein hypersensitivity. Hemofil M and Monoclate-P contain trace amounts of murine proteins from the purification process.[56332] [56326] Recombinate contains trace amounts of bovine, hamster, and mouse proteins.[56325] Helixate FS, Kogenate FS, Advate, Adynovate, and Kovaltry contain trace amounts of hamster and mouse proteins.[56320] [56321] [56329] [56366] [60296] [60650] Afstyla, Novoeight, and Xyntha contain trace amounts of hamster proteins.[49402] [56302] [60830] Esperoct is contraindicated in patients with hamster protein hypersensitivity.[63978] Jivi is contraindicated in patients with hamster protein hypersensitivity, murine protein hypersensitivity, or polyethylene glycol (PEG) hypersensitivity.[63486] Advate, Adynovate, and Monoclate-P contain mannitol and are contraindicated in patients who have a mannitol hypersensitivity.[56320] [56326] [60296] Advate, Adynovate, Afstyla, Helixate FS, Koate-DVI, Kogenate FS, Kovaltry, Novoeight, Recombinate, and Xyntha contain polysorbate 80 and are contraindicated in patients with a polysorbate 80 hypersensitivity.[49402] [56302] [56320] [56325] [56365] [56366] [60296] [60650] [60830] [61389] Use Recombinate with caution in patients with a latex hypersensitivity; certain components used in the packaging contain natural rubber latex.[56325]

        Hemophilia A patients with human immunodeficiency virus (HIV) infection or who are HIV seropositive may benefit from treatment with ultra-pure, antihemophilic factor (AHF) products (i.e., monoclonal antibody purified or recombinant products). Studies have shown improved immune function in hemophilia A patients receiving high purity factor VIII products.[25569]

        Once clotting has been normalized by treatment with antihemophilic factor, AHF, factor VIII, hemophilic patients with cardiovascular risk factors or cardiac disease may be at the same risk to develop cardiovascular events as non-hemophilic patients.[56366]

        The formation of factor VIII inhibitors (neutralizing antibodies) may occur after antihemophilic factor, AHF, factor VIII administration. Previously untreated patients are at greatest risk for inhibitor development with all factor VIII products. Monitor all patients for the development of inhibitors by appropriate clinical observation and laboratory tests. Perform testing for factor VIII inhibitors if plasma factor VIII concentrations are not achieved or if bleeding is not controlled by an appropriate dose.[56302] [63978]

        Mechanism of Action

        Factor VIII acts in the coagulation cascade to accelerate the cleavage of factor X by activated factor IX. Factor VIII dramatically increases the maximal velocity of the reaction. Low concentrations of factor VIII (0.2 ng/mL of plasma) are required for normal hemostasis. A severe decrease (more than 80%) or lack of the factor lead to the bleeding disorder known as hemophilia A or classical hemophilia. Factor VIII circulates in a noncovalent complex with von Willebrand factor (vWF). The complex with vWF increases the synthesis of factor VIII, protects factor VIII from proteolysis, and concentrates factor VIII at the site of active bleeding. Factor VIII cannot become part of the "tenase" complex (the calcium-dependent complex of activated factor VIII [factor VIIIa], factor IXa and phospholipid) until it is released from vWF since vWF inhibits the binding of factor VIII to phospholipid. The release of factor VIII from vWF requires cleavage of the factor VIII light chain by thrombin or factor Xa. This results in activation of factor VIII and binding of factor VIIIa to phospholipid surfaces of damaged cells and activated platelets. Factor VIIIa is unstable and rapidly loses its activity. Factor VIIIa undergoes subunit disassociation and is inactivated via proteolytic cleavage by activated protein C.[25742]

         

        The increase in plasma factor VIII activity produced by antihemophilic factor (AHF) may vary by product. In general, 1 International Unit/kg of AHF increases plasma factor VIII activity by approximately 2 International Units/dL.[56302][56332][60156][63978] Additionally, 1 International Unit/kg of Humate-P increases the von Willebrand Factor:Ristocetin Cofactor (vWF:RCo) activity by 5 International Units/dL.[56306]

        Pharmacokinetics

        Antihemophilic factor, AHF, factor VIII is administered intravenously. Factor VIII products are labeled in terms of AHF potency (FVIII:C activity) as International Units. Antihemophilic factor/von Willebrand factor complex products also include the activity of von Willebrand factor expressed as von Willebrand factor:Ristocetin Cofactor (vWF:RCo) and labeled as International Units. These units are referenced to a World Health Organization international standard where 1 International Unit indicates the amount of factor VIII or vWF:RCo present in 1 mL of fresh-pooled plasma.[56306]

         

        The distribution of AHF is limited to the plasma. The half-life of plasma-derived AHF and recombinant AHF are similar and is approximately 15 hours (range 8 to 17.5 hours).[56325][56326][56329] The mean in vivo recovery (IVR) of AHF products is 1.9 to 2.74 International Units/dL per International Units/kg and indicates the increase in factor concentration achieved after infusion of a given amount of factor product.[56320][56326] Porcine AHF (i.e., Hyate:C) has a half-life of approximately 7 hours (range 2 to 9 hours). The half-life of all AHF products is reduced in patients with factor VIII inhibitors.

         

        The half-life of vWF:RCo in patients receiving antihemophilic factor/von Willebrand factor complex is 7.67 to 15.8 hours. The in vivo recovery (IVR) of vWF:RCo is 1.9 to 3.3 International Units/dL per International Units/kg.[56305][56306][56307]

        Route-Specific Pharmacokinetics

        Intravenous Route

        After IV administration, AHF is quickly cleared from the plasma. The peak effect of activity occurs 1 to 2 hours after IV administration.

        Special Populations

        Pediatrics

        During pharmacokinetic trials of recombinant antihemophilic factor (Novoeight), children demonstrated significantly faster clearance than adolescents and adults. The mean clearance was 29% to 60% (clotting assay) and 34% to 67% (chromogenic assay) higher. The mean clearance was 4.6 to 6.26 mL/kg/hour and 3.7 to 5.02 mL/kg/hour in children 0 to 5 years and 6 to 11 years, respectively, compared to a mean clearance of 2.87 to 3.74 mL/kg/hour in adults. The mean half-life was 7.7 to 10 hours and 8 to 9.4 hours in pediatric patients 0 to 5 years and 6 to 11 years, respectively, compared to a mean half-life of 10.8 to 12 hours in adults.[56302] In pharmacokinetic trials of another recombinant antihemophilic factor (Adynovate), children also demonstrated significantly faster clearance than adolescents and adults. The mean clearance was 3.53 mL/kg/hour for children 2 to 5 years and 3.11 mL/kg/hour for children 6 to 11 years, compared with 3.87 mL/kg/hour for adolescents 12 to 17 years and 2.27 mL/kg/hour for adults. Corresponding mean elimination half-lives were 11.8, 12.4, 13.43, and 14.69 hours, respectively.[60296] Similar trends in pharmacokinetic parameters have been observed with other antihemophilic factor products.[56320][56321]

        Pregnancy/Breast-feeding

        pregnancy

        There are no adequate and well-controlled studies using antihemophilic factor, AHF, factor VIII in pregnancy to determine whether there is a drug-associated risk as hemophilia mainly affects males. Animal reproduction studies have not been conducted.[49402] [56302] [60830] [63978]

        breast-feeding

        There are no data describing the presence of antihemophilic factor, AHF, factor VIII in breast milk, the effect on the breast-fed infant, or the effect on milk production. Consider the developmental and health benefits of breast-feeding along with the mother's clinical need for AHF and any potential adverse effects on the breast-fed infant from AHF or the mother's underlying condition.[56302] [60830] [63978]
