🎯 Indications and Usage ▾
1 INDICATIONS AND USAGE Humate-P is an Antihemophilic Factor/von Willebrand Factor (VWF) Complex (Human) indicated for: Hemophilia A – Treatment and prevention of bleeding in adults ( 1.1 ). Von Willebrand disease (VWD) – in adults and pediatric patients in the (1) Treatment of spontaneous and trauma-induced bleeding episodes, and (2) Prevention of excessive bleeding during and after surgery. This applies to patients with severe VWD as well as patients with mild to moderate VWD where the use of desmospressin is known or suspected to be inadequate ( 1.2 ).
Humate-P is not indicated for the prophylaxis of spontaneous bleeding episodes in VWD.
1.1Hemophilia A Humate-P, Antihemophilic Factor/von Willebrand Factor Complex (Human), is indicated for treatment and prevention of bleeding in adults with hemophilia A (classical hemophilia).
1.2Von Willebrand Disease (VWD) Humate-P is also indicated in adult and pediatric patients with von Willebrand disease (VWD) for: (1) treatment of spontaneous and trauma-induced bleeding episodes, and (2) prevention of excessive bleeding during and after surgery. This applies to patients with severe VWD as well as patients with mild to moderate VWD where use of desmopressin (DDAVP) is known or suspected to be inadequate. Controlled clinical trials to evaluate the safety and efficacy of prophylactic dosing with Humate-P to prevent spontaneous bleeding have not been conducted in VWD subjects (see Clinical Studies [14] ) .
⏱️ Dosage and Administration ▾
2 DOSAGE AND ADMINISTRATION For intravenous use only. Hemophilia A One IU of factor VIII (FVIII) activity per kg body weight increases the circulating FVIII level by approximately
2.0IU/dL. Individualize dosage based on the patient's weight, type and severity of hemorrhage, FVIII level, and presence of inhibitors (see Table 1 for dosing recommendations) ( 2.1 ). VWD Treatment of bleeding episodes – Administer 40-80 IU VWF:Ristocetin Cofactor (RCo) per kg body weight every 8-12 hours ( 2.2 ).
Prevention of excessive bleeding during and after surgery for all types of VWD ( 2.3 ). Type of Surgery (see Table 3 for complete surgical dosing) Calculation of Loading Dose Initial maintenance dose should be half the loading dose (see Table 4 for monitoring recommendations). IU = International Units.
BW = body weight. Major Surgery ( 2.3 ) Δ Δ = Target peak plasma VWF:RCo level – baseline plasma VWF:RCo level. VWF:RCo × BW (kg) IVR IVR = in vivo recovery as measured in the patient.
If the IVR is unknown, use
2.0IU/dL per IU/kg. = IU VWF:RCo required Minor/Oral Surgery Oral surgery is defined as extraction of fewer than three teeth, if the teeth are non-molars and have no bony involvement. ( 2.3 ) Δ VWF:RCo × BW (kg) IVR = IU VWF:RCo required Emergency Surgery ( 2.3 ) Administer a dose of 50-60 IU VWF:RCo/kg BW
2.1Therapy for Hemophilia A One IU of Factor VIII (FVIII) activity per kg body weight will increase the circulating FVIII level by approximately
2.0International Units (IU)/dL. Dosage must be individualized based on the patient's weight, type and severity of hemorrhage, FVIII level, and presence of inhibitors. Judge the adequacy of treatment by clinical effects and, in all cases, adjust doses as needed based on clinical judgment and on frequent monitoring of the patient's FVIII level.
Table 1 provides dosing recommendations for the treatment of hemophilia A in adults. Table 1: Dosing Recommendations for the Treatment of Hemophilia A in Adults 1 Hemorrhagic Event Dosage (IU FVIII:C/kg Body Weight) IU = International Units. Minor hemorrhage: Early joint or muscle bleed Severe epistaxis Loading dose 15 IU FVIII:C/kg to achieve a FVIII:C plasma level of approximately 30% of normal; one infusion may be sufficient.
If needed, half of the loading dose may be given once or twice daily for 1-2 days. Moderate hemorrhage: Advanced joint or muscle bleed Neck, tongue, or pharyngeal hematoma (without airway compromise) Tooth extraction Severe abdominal pain Loading dose 25 IU FVIII:C/kg to achieve a FVIII:C plasma level of approximately 50% of normal, followed by 15 IU FVIII:C/kg every 8-12 hours for the first 1-2 days to maintain the FVIII:C plasma level at 30% of normal. Continue the same dose once or twice daily for up to 7 days or until adequate wound healing is achieved.
Life-threatening hemorrhage: Major surgery Gastrointestinal bleeding Neck, tongue, or pharyngeal hematoma (with potential for airway compromise) Intracranial, intraabdominal, or intrathoracic bleeding Fractures Initially 40-50 IU FVIII:C/kg, followed by 20-25 IU FVIII:C/kg every 8 hours to maintain the FVIII:C plasma level at 80-100% of normal for 7 days. Continue the same dose once or twice daily for another 7 days to maintain the FVIII:C level at 30-50% of normal.
2.2Treatment of Bleeding Episodes in VWD Administer 40 to 80 International Units (IU) VWF:RCo (corresponding to 17 to 33 International Units (IU) FVIII in Humate-P) per kg body weight every 8 to 12 hours. Adjust the dosage based on the extent and location of bleeding. Administer repeat doses as long as needed based on monitoring of appropriate clinical and laboratory measures ( see Warnings and Precautions [5.2 and 5.3] ).
Expected levels of VWF:RCo are based on an expected in vivo recovery (IVR) of
2.0International Units (IU)/dL rise per International Unit (IU)/kg VWF:RCo administered. The administration of 1 International Unit (IU) of FVIII per kg body weight can be expected to lead to a rise in circulat… [Excerpted — this section continues on DailyMed.]

⛔ Contraindications ▾
4 CONTRAINDICATIONS Humate-P is contraindicated in individuals who have had an anaphylactic or severe systemic reaction to antihemophilic factor or von Willebrand factor preparations. Anaphylactic or severe systemic reaction to antihemophilic factor or VWF preparations ( 4 ).
⚠️ Warnings and Cautions ▾
5 WARNINGS AND PRECAUTIONS VWD patients receiving Humate-P may be at risk of developing thromboembolic events ( 5.1 ). Monitor for intravascular hemolysis and decreasing hematocrit values in patients with A, B, and AB blood groups who are receiving large or frequent doses ( 5.2 ). Monitor VWF:RCo and FVIII levels in VWD patients, especially those undergoing surgery ( 5.3 ).
Products made from human plasma may contain infectious agents (e.g., viruses, and, theoretically, the Creutzfeldt-Jakob disease (CJD) agent ( 5.4 ).
5.1Thromboembolic Events (VWD Patients) Thromboembolic events have been reported in VWD patients receiving Antihemophilic Factor/von Willebrand Factor Complex replacement therapy, especially in the setting of known risk factors for thrombosis. 3,4 Early reports indicate a higher incidence may occur in females. Endogenous high levels of FVIII have also been associated with thrombosis, but no causal relationship has been established.
Exercise caution and consider antithrombotic measures in all at-risk VWD patients who are receiving coagulation factor replacement therapy.
5.2Monitoring for Intravascular Hemolysis Humate-P contains blood group isoagglutinins (anti-A and anti-B). When doses are very large or need to be repeated frequently (for example, when inhibitors are present or when pre- and post-surgical care is involved), monitor patients of blood groups A, B, and AB for signs of intravascular hemolysis and decreasing hematocrit values and treat appropriately.
5.3Monitoring VWF:RCo and FVIII Levels Monitor the VWF:RCo and FVIII levels of VWD patients receiving Humate-P using standard coagulation tests, especially in cases of surgery. It is advisable to monitor trough VWF:RCo and FVIII:C levels at least once a day in order to adjust the dosage of Humate-P as needed to avoid excessive accumulation of coagulation factors (s ee Dosage and Administration [2.2 , 2.3] ).
5.4Transmission of Infectious Agents Humate-P is made from human plasma. Products made from human plasma may contain infectious agents (e.g., viruses and theoretically, the Creutzfeldt-Jakob disease [CJD] agent) that can cause disease ( see Description [11] and Patient Counseling Information [17.1] ). The risk that such products will transmit an infectious agent has been reduced by screening plasma donors for prior exposure to certain viruses, by testing for the presence of certain current virus infections, and by inactivating and/or removing certain viruses during manufacturing ( see Description [11.1] for virus reduction measures ).
Despite these measures, such products can still potentially transmit disease. There is also the possibility that unknown infectious agents may be present in such products. Thus the risk of transmission of infectious agents cannot be eliminated completely.
Report all infections thought by a physician possibly to have been transmitted by this product to CSL Behring Pharmacovigilance at 1-866-915-6958 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch . Some viruses, such as Parvovirus B19 virus (B19V) or hepatitis A (HAV), are particularly difficult to remove or inactivate. B19V may most seriously affect pregnant women and immune-compromised individuals.
Although the overwhelming number of B19V and HAV cases are community acquired, reports of these infections have been associated with the use of some plasma-derived products. Therefore, physicians should be alert to the potential symptoms of B19V and HAV infections ( see Patient Counseling Information [17.1] ). Symptoms of B19V may include low-grade fever, rash, arthralgias, and transient symmetric, nondestructive arthritis.
Diagnosis is often established by measuring B19V-specific IgM and IgG antibodies. Symptoms of HAV include low-grade fever, anorexia, nausea, vomiting, fatigue, and jaundice. A diagnosis may be established by measuring specific IgM antibodies.
Physicians should strongly consider administration of hepatitis A and hepatitis B vaccines to individuals re… [Excerpted — this section continues on DailyMed.]
🤒 Adverse Reactions ▾
6 ADVERSE REACTIONS The most serious adverse reaction observed in patients receiving Humate-P is anaphylaxis. Thromboembolic events have also been observed in patients receiving Humate-P for the treatment of VWD ( see Warnings and Precautions [5.1] ). Reports of thromboembolic events in VWD patients with other thrombotic risk factors receiving coagulation factor replacement therapy have been obtained from spontaneous reports, published literature, and a European clinical study.
In some cases, inhibitors to coagulation factors may occur. However, no inhibitor formation was observed in any of the clinical studies. In patients receiving Humate-P in clinical studies for treatment of VWD, the most commonly reported adverse reactions observed by >5% of subjects are allergic-anaphylactic reactions (including urticaria, chest tightness, rash, pruritus, and edema).
For patients undergoing surgery, the most common adverse reactions are postoperative wound and injection-site bleeding, and epistaxis. Most common adverse reactions observed by >5% of subjects after receiving Humate-P are allergic-anaphylactic reactions (e.g., urticaria, chest tightness, rash, pruritus, edema) and, in patients undergoing surgery, postoperative wound and injection-site bleeding, and epistaxis ( 6 ). To report SUSPECTED ADVERSE REACTIONS, contact CSL Behring Pharmacovigilance at 1-866-915-6958 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch.
6.1Clinical Studies Experience Because clinical studies are conducted under widely varying conditions, the adverse reaction rates observed cannot be directly compared to rates in other clinical trials and may not reflect the rates observed in practice. Treatment of Bleeding Episodes in VWD Allergic symptoms, including allergic reaction, urticaria, chest tightness, rash, pruritus, and edema, were reported in 6 of 97 (6%) subjects in a Canadian retrospective study ( see Clinical Studies [14.1] ). Four of 97 (4%) subjects experienced seven adverse events that were considered to have a possible or probable relationship to Humate-P.
These included chills, phlebitis, vasodilation, paresthesia, pruritus, rash, and urticaria. All were mild in intensity with the exception of a moderate case of pruritus. In a prospective, open-label safety and efficacy study of Humate-P in VWD subjects with serious life- or limb-threatening bleeding or undergoing emergency surgery, seven of 71 (10%) subjects experienced nine adverse reactions.
These were one occurrence each of mild vasodilation and mild pruritis; two occurrences of mild paresthesia; and one occurrence each of moderate peripheral edema and extremity pain and severe pseudothrombocytopenia (platelet clumping with a false low reading). Humate-P was discontinued in the subject who experienced the peripheral edema and extremity pain. Prevention of Excessive Bleeding During and After Surgery in VWD Among the 63 VWD subjects who received Humate-P for prevention of excessive bleeding during and after surgery, including one subject who underwent colonoscopy without the planned polypectomy, the most common adverse events were postoperative hemorrhage (35 events in 19 subjects with five subjects experiencing bleeding at up to three different sites), postoperative nausea (15 subjects), and postoperative pain (11 subjects).
Table 5 presents the postoperative hemorrhagic adverse events. Table 5: Hemorrhagic Adverse Events in 63 Surgical Subjects Adverse Event Surgical Procedure Category Number of Subjects/Events Onset On = on-therapy; onset while receiving Humate-P or within 1 day of completing Humate-P administration.

👥 Use in Specific Populations ▾
8 USE IN SPECIFIC POPULATIONS Pregnancy: No human or animal data. Use only if clearly needed ( 8.1 ). The hemostatic efficacy of Humate-P has been studied in 34 pediatric subjects with VWD ( 8.4 ). Based on the data from a subset of these subjects, age had no effect on the pharmacokinetics of VWF:RCo ( 12.3 ).
8.1Pregnancy Pregnancy Category C. Animal reproduction studies have not been conducted with Humate-P. It is also not known whether Humate-P can cause fetal harm when administered to a pregnant woman or can affect reproduction capacity. Humate-P should be given to a pregnant woman only if clearly needed.
8.2Labor and Delivery It is not known whether Humate-P can cause harm to the mother or the fetus when administered during labor and delivery. Humate-P should be given during labor and delivery only if clearly needed.
8.3Nursing Mothers It is not know whether this drug is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when Humate-P is administered to a nursing woman.
8.4Pediatric Use Hemophilia A Adequate and well-controlled studies with long-term evaluation of joint damage have not been done in pediatric subjects. Joint damage may result from suboptimal treatment of hemarthroses. VWD The safety and effectiveness of Humate-P for the treatment of VWD was demonstrated in 26 pediatric subjects, including infants, children, and adolescents, but have not been evaluated in neonates.
The safety of Humate-P for the prevention of excessive bleeding during and after surgery was demonstrated in eight pediatric subjects (ages 3 to 15) with VWD. Of the 34 pediatric subjects studied for either treatment of bleeding episodes in VWD or prevention of excessive bleeding during and after surgery, four were infants (1 month to under 2 years of age), 23 were children (2 through 12 years), and seven were adolescents (13 through 15 years). As in adults, pediatric patients should be dosed based on body weight (kg) ( see Dosage and Administration [2.2 , 2.3] ).
8.5Geriatric Use Clinical studies of Humate-P did not include sufficient numbers of subjects 65 years of age and older to determine whether they respond differently from younger subjects. As for all patients, dosing for geriatric patients should be appropriate to their overall situation.

🧬 Clinical Pharmacology ▾
12 CLINICAL PHARMACOLOGY
12.1Mechanism of Action The active components of Humate-P consist of two different noncovalently bound proteins (FVIII and VWF). FVIII is an essential cofactor in activation of factor X, leading ultimately to the formation of thrombin and, subsequently, fibrin. VWF promotes platelet aggregation and platelet adhesion on damaged vascular endothelium; activated platelets interact with clotting proteins to form a clot.
VWF also serves as a stabilizing carrier protein for the procoagulant protein FVIII. 7,8 The activity of VWF is measured as VWF:RCo.
12.3Pharmacokinetics Hemophilia A After infusion of Humate-P, a rapid increase of plasma FVIII:C is followed by a rapid decrease in activity and, subsequently, a slower rate of decrease in activity. Studies with Humate-P in subjects with hemophilia A have demonstrated a mean half-life of 12.2 (range: 8.4 to 17.4) hours. VWD The pharmacokinetics of Humate-P were studied in 41 subjects in a US study and in 28 subjects in a European study ( see Clinical Studies [14.2] ).
In both studies, subjects were evaluated in the nonbleeding state prior to a surgical procedure. Table 8 summarizes the pharmacokinetics of Humate-P based on these studies. Wide inter-subject variability was observed in pharmacokinetic values obtained from these studies.

2.4IU/dL per IU/kg (1.1-4.2)
1.9IU/dL per IU/kg (0.6-4.5) The multimeric patterns of Humate-P in the US study, were measured in 13 subjects with type 3 VWD; 11 had absent or barely detectable multimers at baseline. Of those 11 subjects, all had some high molecular weight multimers present 24 hours after infusion of Humate-P. In the European study, infusion of Humate-P corrected the defect of the multimer pattern in subjects with types 2A and 3 VWD.
High molecular weight multimers were detectable until at least 8 hours after infusion. Based on the small sample size evaluation, it appears that age, sex, and type of VWD have no impact on the pharmacokinetics of VWF:RCo.

Each vial of Humate-P contains the labeled amount of von Willebrand Factor:Ristocetin Cofactor (VWF:RCo) and FVIII activity expressed in International Units (IU) ( see Dosage Forms and Strengths [3] ). An International Unit (IU) is defined by the current international standard established by the World Health Organization. One International Unit (IU) of VWF:RCo or FVIII is approximately equal to the amount of VWF:RCo or FVIII in 1.0 mL of fresh-pooled human plasma.
The average ratio of VWF:RCo to FVIII is 2.4:1. When reconstituted with the volume of diluent (sterile water) provided, each mL of Humate-P contains 72 to 224 International Units (IU) VWF:RCo activity This correlates to a VWF:RCo to FVIII activity average ratio of 2.4:1, which is used to calculate the nominal values of VWF:RCo activity and is the average VWF:RCo activity. , 40 to 80 International Units (IU) FVIII activity, 15 to 33 mg of glycine, 3.5 to 9.3 mg of sodium citrate, 2 to 5.3 mg of sodium chloride, 8 to 16 mg of Albumin (Human), 2 to 14 mg of other proteins, and 10 to 20 mg of total proteins.
Humate-P contains no preservative. Humate-P has been demonstrated in several studies to contain the high molecular weight multimers of VWF. This component is considered to be important for correcting the coagulation defect in patients with VWD.
5 When administered to patients with VWD (types 1, 2, or 3), bleeding time decreased. This outcome was correlated with the presence of a multimeric composition of VWF similar to that found in normal plasma. 6 Humate-P contains anti-A and anti-B blood group isoagglutinins ( see Warnings and Precautions [5.2] ).
The pooled human plasma used to produce Humate-P is collected from licensed facilities in the US. All source plasma used in the manufacture of Humate-P is tested by FDA-licensed Nucleic Acid Tests (NAT) for hepatitis C virus (HCV) and human immunodeficiency virus-1 (HIV-1) and found to be nonreactive (negative). The source plasma is also tested by an investigational NAT for hepatitis B virus (HBV) and found to be nonreactive (negative).
The purpose of the HBV test is to detect low levels of viral material; however, the significance of a nonreactive (negative) result has not been established.
11.1Virus Reduction Capacity The manufacturing procedure for Humate-P includes multiple processing steps that reduce the risk of virus transmission. The manufacturing process has been demonstrated to reduce the risk of virus transmission in an additive manner: 1) cryoprecipitation; 2) Al(OH) 3 adsorption, glycine precipitation, and NaCl precipitation, studied in combination; and 3) pasteurization in aqueous solution at 60°C for 10 hours. Total mean cumulative virus reductions ranged from 6.0 to ≥11.3 log 10 as shown in Table 7.

💬 Information for Patients ▾
17 PATIENT COUNSELING INFORMATION Inform patients that Humate-P is made from human plasma (part of the blood) and may contain infectious agents that can cause disease (e.g., viruses and, theoretically, the CJD agent). Explain that the risk that Humate-P may transmit an infectious agent has been reduced by screening plasma donors, by testing the donated plasma for certain virus infections, and by inactivating and/or removing certain viruses during manufacturing ( see Warnings and Precautions [5.4] ). Inform patients that some viruses, such as B19V and HAV, may be particularly difficult to remove or inactivate.
Advise patients, especially pregnant women and immune-compromised individuals, to report low-grade fever, rash, joint pain, anorexia, nausea, vomiting, fatigue, and jaundice ( see Warnings and Precautions [5.4] ).
🍼 Nursing Mothers ▾
8.3Nursing Mothers It is not know whether this drug is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when Humate-P is administered to a nursing woman.
🧬 Pharmacokinetics ▾
12.3Pharmacokinetics Hemophilia A After infusion of Humate-P, a rapid increase of plasma FVIII:C is followed by a rapid decrease in activity and, subsequently, a slower rate of decrease in activity. Studies with Humate-P in subjects with hemophilia A have demonstrated a mean half-life of 12.2 (range: 8.4 to 17.4) hours. VWD The pharmacokinetics of Humate-P were studied in 41 subjects in a US study and in 28 subjects in a European study ( see Clinical Studies [14.2] ).
In both studies, subjects were evaluated in the nonbleeding state prior to a surgical procedure. Table 8 summarizes the pharmacokinetics of Humate-P based on these studies. Wide inter-subject variability was observed in pharmacokinetic values obtained from these studies.

2.4IU/dL per IU/kg (1.1-4.2)
1.9IU/dL per IU/kg (0.6-4.5) The multimeric patterns of Humate-P in the US study, were measured in 13 subjects with type 3 VWD; 11 had absent or barely detectable multimers at baseline. Of those 11 subjects, all had some high molecular weight multimers present 24 hours after infusion of Humate-P. In the European study, infusion of Humate-P corrected the defect of the multimer pattern in subjects with types 2A and 3 VWD.
High molecular weight multimers were detectable until at least 8 hours after infusion. Based on the small sample size evaluation, it appears that age, sex, and type of VWD have no impact on the pharmacokinetics of VWF:RCo.
🔬 Clinical Studies ▾
14 CLINICAL STUDIES Controlled clinical studies to evaluate the safety and efficacy of prophylactic dosing with Humate-P to prevent spontaneous bleeding have not been conducted in VWD subjects. Adequate data are not presently available on which to evaluate or to base dosing recommendations in this setting.
14.1Treatment of Bleeding Episodes in VWD Clinical efficacy of Humate-P in the control of bleeding in subjects with VWD was determined by a retrospective review of clinical safety and efficacy data obtained from 97 Canadian VWD subjects who received product under an Emergency Drug Release Program. The dosage schedule and duration of therapy were determined by the medical practitioner. There were 514 requests for product use for surgery, bleeding, or prophylaxis in the 97 subjects.
Of these, Humate-P was not used in 151 cases, and follow-up safety and/or efficacy information was available for 303 (83%) of the remaining 363 requests. In many cases, Humate-P from a single request was used for several treatment courses in one subject. Therefore, there are more reported treatment courses than requests.
Humate-P was administered to 97 subjects in 530 treatment courses: 73 for surgery, 344 for treatment of bleeding, and 20 for prophylaxis of bleeding. The majority of the 93 "other" uses involved dental procedures, diagnostic procedures, prophylaxis prior to a procedure, or test doses. Table 9 summarizes the dosing information (all subjects) for bleeding episodes.

14.2Prevention of Excessive Bleeding During and After Surgery in VWD Two prospective, open-label, non-controlled, multicenter clinical studies, one in the US and one in Europe, investigated the safety and hemostatic efficacy of Humate-P in subjects with VWD undergoing surgery. • US clinical study – The primary objective of this study was to demonstrate the safety and hemostatic efficacy of Humate-P in preventing excessive bleeding in adult and pediatric subjects with VWD undergoing surgery. The 35 subjects (21 female and 14 male) ranged in age from 3 to 75 years (mean 32.9); seven were age 15 or younger and two were age 65 or older.
Twelve subjects had type 1 VWD, two had type 2A, three had type 2B, five had type 2M, and 13 had type 3. Twenty-eight of the surgical procedures were classified as major (e.g., orthopedic joint replacement, intracranial surgery, multiple tooth extractions, laparoscopic cholecystectomy), four as minor (e.g., placement of intravenous access device), and three subjects had oral surgery Oral surgery is defined as extraction of fewer than three teeth, if the teeth are non-molars and have no bony involvement. Extraction of more than one impacted wisdom tooth is considered major surgery due to the expected difficulty of the surgery and the expected blood loss, particularly in subjects with type 2A or type 3 VWD.
Extraction of more than two teeth is c… [Excerpted — this section continues on DailyMed.]
