CLINICAL PHARMACOLOGY Mechanism Of Action ADYNOVATE, a PEGylated form of recombinant antihemophilic factor (ADVATE), [see DESCRIPTION], temporarily replaces the missing coagulation factor VIII needed for effective hemostasis in congenital hemophilia A patients. ADYNOVATE exhibits an extended terminal half-life through pegylation of the parent molecule, ADVATE, which reduces binding to the physiological factor VIII clearance receptor (LRP1). Pharmacodynamics Hemophilia A is a disorder characterized by a deficiency of functional coagulation factor VIII, resulting in a prolonged, patient plasma clotting time as measured by the activated partial thromboplastin time (aPTT). Treatment with ADYNOVATE normalizes the aPTT over the effective dosing period. The administration of ADYNOVATE increases plasma levels of factor VIII and can temporarily correct the coagulation defect in hemophilia A patients. Pharmacokinetics The pharmacokinetics (PK) of ADYNOVATE was evaluated in a multi-center, prospective, open label study and compared with ADVATE in 26 subjects prior to initiation of prophylactic treatment with ADYNOVATE and in 22 subjects after 6 months of treatment with ADYNOVATE. A single dose of 45 IU/kg was utilized for both products. The PK parameters, as shown in Table 3, were based on plasma coagulation factor VIII activity measured by the one-stage clotting assay and are presented by age groups (adults and adolescents). The terminal plasma half-life of ADYNOVATE was 1.4- to 1.5-fold longer than that of ADVATE. Incremental recovery was comparable between both products. The PK parameters determined after 6 months of prophylactic treatment with ADYNOVATE were consistent with the initial parameter estimates.

Median including all subjects is 2.78 mL/(kg·h). Pediatric Pharmacokinetics Pharmacokinetic profiles of ADYNOVATE have not been established in pediatric patients less than 12 years old. Clinical Studies The safety, efficacy, and PK of ADYNOVATE were evaluated in a multicenter, open-label, prospective, non-randomized, two-arm clinical trial that compared the efficacy of a twice weekly prophylactic treatment regimen to on-demand treatment and determined hemostatic efficacy in the treatment of bleeding episodes. A total of 137 male PTPs (12 to 65 years of age) with severe hemophilia A received at least one infusion with ADYNOVATE. Twenty-five of the 137 subjects were adolescents (12 to less than 18 years of age). Subjects received either prophylactic treatment (n = 120) with ADYNOVATE at a dose of 40-50 IU per kg twice weekly or on-demand treatment (n = 17) with ADYNOVATE at a dose of 10-60 IU per kg for a 6-month period. The mean (SD) dose per prophylaxis infusion was 44.4 (3.9) IU per kg with a median dosing interval of 3.6 days. There were 91 out of 98 (93%) subjects previously treated prophylactically prior to enrollment, who experienced a reduction in dosing frequency during routine prophylaxis in the study, with a median reduction of 33.7% (approximately one more day between doses). One hundred eighteen of 120 (98%) prophylaxis subjects remained on the starting recommended regimen without dose adjustment, and 2 subjects increased their dose to 60 IU/kg during prophylaxis due to bleeding in target joints. On-demand Treatment and Control of Bleeding Episodes A total of 518 bleeding episodes were treated with ADYNOVATE in the per-protocol population, i.e. dosed according to the protocol specific dosing requirements. Of these, 361 bleeding episodes (n=17 subjects) occurred in the on-demand arm and 157 (n=61 subjects) occurred in the prophylaxis arm. The median dose per infusion to treat all bleeding episodes in the per-protocol population was 29 (Q1: 20.0; Q3: 39.2) IU per kg. The median dose per infusion to treat a minor, moderate, or severe/major bleeding episode in the per-protocol population was 25.5 (Q1: 16.9; Q3: 37.6) IU/kg, 30.9 (Q1: 23.0; Q3: 43.1) IU/kg, or 36.4 (Q1: 29.0; Q3: 44.5) IU/kg, respectively. A total of 591 bleeding episodes were treated with ADYNOVATE in the treated population, which was identical to the safety analysis set of subjects assigned to routine prophylaxis or on-demand treatment with ADYNOVATE and who received at least one dose of the product. Of these, 361 bleeding episodes (n=17 subjects) occurred in the on-demand arm and 230 bleeding episodes (n=75 subjects) occurred in the routine prophylaxis arm. Efficacy in control of bleeding episodes is summarized in Table 4.

Required more than 1 infusion for complete resolution; None defined as no improvement or condition worsened. Routine Prophylaxis A total of 120 subjects (treated population) received a twice a week regimen in the prophylaxis arm, and an additional 17 subjects were treated episodically in the on-demand arm. In the treated population, the median [mean] annualized bleed rate (ABR) in the on-demand treatment arm was 41.5 [40.8] compared to 1.9 [4.7] while on a twice a week prophylaxis regimen (Table 5). In the per-protocol population, the median [mean] annualized bleed rate (ABR) in the on-demand treatment arm was 41.5 [40.8] compared to 1.9 [3.7] while on a twice a week prophylaxis regimen. Using a negative binomial model to estimate the ABR, there was a significant reduction in the ABR (p < 0.0001) for subjects in the prophylaxis arm compared to the on-demand arm. Table 5: Annualized Bleed Rate by Treatment for ≥ 12 years of age (Treated Population) Bleeding Episode Etiology On-Demand Treatment Routine Prophylaxis Treatment Median Mean (SD) Median Mean (SD) Overall 41.5 40.8 (16.3) 1.9 4.7 (8.6) Joint 38.1 34.7 (15.1) 0.0 2.9 (8.0) Non-Joint 3.7 6.1 (6.7) 0.0 1.8 (3.0) Spontaneous 21.6 26.0 (19.6) 0.0 2.9 (7.1) Traumatic 9.3 14.9 (15.3) 0.0 1.8 (3.1) In the treated population, the median [mean] ABR for the 23 adolescent subjects age 12 to < 18 years of age on routine prophylaxis was 2.1 [5.2] compared to a median [mean] ABR of 1.9 [4.6] for the 97 subjects 18 years and older. Reduction in ABR between the treatment arms was observed regardless of baseline subgroups examined, including age, presence or absence of target joints, and pre-study treatment regimen. The majority of the bleeding episodes during prophylaxis (95%) were of minor/moderate severity. Forty-five out of 120 subjects (38%) experienced no bleeding episodes and 68 out of 120 subjects (57%) experienced no joint bleeding episodes in the prophylaxis arm. Of those subjects who were compliant to regimen (per-protocol population), 40 out of 101 subjects (40%) experienced no bleeding episodes. All subjects in the on-demand arm experienced a bleeding episode, including a joint bleeding episode.

Find Lowest Prices on ADYNOVATE [Antihemophilic Factor (Recombinant), PEGylated] Lyophilized Powder for Reconstitution for Intravenous Injection DESCRIPTION ADYNOVATE, Antihemophilic Factor (Recombinant), PEGylated, is formulated as a sterile, non-pyrogenic, white to off-white lyophilized powder for reconstitution for intravenous injection. The product is supplied in single-use vials containing nominal (approximate) potencies of 250, 500, 1000, or 2000 international units (IU). Each vial of ADYNOVATE is labeled with the actual factor VIII activity in IU determined using one-stage clotting assay, using a reference material calibrated against a World Health Organization (WHO) International Standard for factor VIII concentrates. One IU, as defined by the WHO standard for blood coagulation factor VIII, human, is approximately equal to the level of factor VIII activity found in 1 mL of fresh pooled human plasma. When reconstituted with 5 mL sterile water for injection, the final solution contains the following excipients and stabilizer in targeted amounts per vial: Stabilizer and Excipient 5 mL Reconstitution Target Tris (hydroxymethyl) aminomethane 6.1 mg Calcium Chloride 1.2 mg Mannitol 160 mg Sodium Chloride 26.3 mg Trehalose Dihydrate 40 mg Glutathione .04 mg Histidine 7.8 mg Polysorbate 80 0.5 mg ADYNOVATE contains no preservative. The specific activity of ADYNOVATE is 2700 - 8000 IU/mg protein. ADYNOVATE is a recombinant full-length human coagulation factor VIII (2,332 amino acids with a molecular weight (MW) of 280 kDa) covalently conjugated with one or more molecules of polyethylene glycol (MW 20 kDa). [see CLINICAL PHARMACOLOGY]. The therapeutic activity of ADYNOVATE is derived from its parent drug substance, ADVATE [Antihemophilic Factor (Recombinant)], which is produced by recombinant DNA technology from the CHO cell line. ADVATE is purified from the culture medium using a series of chromatography columns. The purification process includes an immunoaffinity chromatography step in which a monoclonal antibody directed against factor VIII is employed to selectively isolate the factor VIII from the medium. The production process includes a dedicated, viral inactivation solvent-detergent treatment step. The ADVATE molecule is then covalently conjugated with the polyethylene glycol, which mainly targets lysine residues. The cell culture, pegylation, purification process and formulation used in the manufacture of ADYNOVATE do not use additives of human or animal origins.

INDICATIONS 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 Routine prophylaxis to reduce the frequency of bleeding episodes ADYNOVATE is not indicated for the treatment of von Willebrand disease. DOSAGE AND ADMINISTRATION For intravenous use after reconstitution only. Dose Each vial label of ADYNOVATE states the actual factor VIII potency in international units. This may be more or less than the nominal vial potency/content. One international unit corresponds to the activity of factor VIII contained in one milliliter of normal human plasma. Initiate treatment under the supervision of a physician experienced in the treatment of hemophilia A. Dosage and duration of treatment depend on the severity of factor VIII deficiency, the location and extent of the bleeding, and the patient's clinical condition. Careful monitoring of replacement therapy is necessary in cases of serious or life-threatening bleeding episodes. Potency assignment is determined using a one-stage clotting assay. Plasma factor VIII levels can be monitored clinically using a one-stage clotting assay. Calculate the dose of ADYNOVATE based on the empirical finding that one international unit of ADYNOVATE per kg body weight increases the plasma factor VIII level by 2 IU per dL of plasma. Use the following formula to estimate the expected in vivo peak increase in factor VIII level expressed as IU per dL (or % of normal) and the dose to achieve a desired in vivo peak increase in factor VIII level: Estimated Increment of factor VIII (IU/dL or % of normal) = [Total Dose (IU)/body weight (kg)] x 2 (IU/dL per IU/kg) Dose (IU) = Body Weight (kg) x Desired factor VIII Rise (IU/dL or % of Normal) x 0.5 (IU/kg per IU/dL) Patients vary in their pharmacokinetic (e.g., clearance, half-life, in vivo recovery) and clinical response. Base the dose and frequency of ADYNOVATE on the individual clinical response. On-demand Treatment and Control of Bleeding Episodes A guide for dosing of ADYNOVATE for the on-demand treatment and control of bleeding episodes is provided in Table 1. Maintain plasma factor VIII activity level at or above the described plasma levels (in IU per dL or % of normal). Table 1: Dosing for On-demand Treatment and Control of Bleeding Episodes Type of Bleeding Target Factor VIII Level (IU/dL or % of normal) Dosea (IU/kg) Frequency of Dosing (hours) Duration of Therapy Minor Early hemarthrosis, mild muscle bleeding, or mild oral bleeding episode. 20-40 10-20 12-24 Until the bleeding is resolved. Moderate Muscle bleeding, moderate bleeding into the oral cavity, definite hemarthroses, and known trauma. 30-60 15-30 12-24 Until the bleeding is resolved. Major Significant gastrointestinal bleeding, intracranial, intra-abdominal or intrathoracic bleeding, central nervous system bleeding, bleeding in the retropharyngeal or retroperitoneal spaces or iliopsoas sheath, fractures, head trauma. 60-100 30-50 8-24 Until bleeding is resolved. aDose (IU/kg) = Desired factor VIII rise (IU/dL or % of normal) x 0.5 (IU/kg per IU/dL) Routine Prophylaxis Administer 40-50 IU per kg body weight 2 times per week. Adjust the dose based on the patient's clinical response. Preparation And Reconstitution Preparation Use aseptic technique (clean and germ free) and a flat work surface during the reconstitution procedure. Reconstitution 1. Allow the vials of ADYNOVATE and diluent to reach room temperature before use. 2. Remove plastic caps from the ADYNOVATE and diluent vials. 3. Cleanse rubber stoppers with a sterile alcohol prep pad and allow to dry prior to use. Figure A 4. Open the BAXJECT II Hi-Flow device package by peeling away the lid, without touching the inside (Figure A). Do not remove the device from the package. 5. Turn the package over. Press straight down to fully insert the clear plastic spike through the diluent vial stopper (Figure B). Figure B 6.

PATIENT INFORMATION ADYNOVATE [Antihemophilic Factor (Recombinant), PEGylated] This leaflet summarizes important information about ADYNOVATE. Please read it carefully before using this medicine. This information does not take the place of talking with your healthcare provider, and it does not include all of the important information about ADYNOVATE. If you have any questions after reading this, ask your healthcare provider. What is the most important information I need to know about ADYNOVATE? Do not attempt to do an infusion to yourself unless you have been taught how by your healthcare provider or hemophilia center. You must carefully follow your healthcare provider's instructions regarding the dose and schedule for infusing ADYNOVATE so that your treatment will work best for you. What is ADYNOVATE? ADYNOVATE is an injectable medicine used to replace clotting factor (factor VIII or antihemophilic factor) that is missing in people with hemophilia A (also called “classic” hemophilia). Hemophilia A is an inherited bleeding disorder that prevents blood from clotting normally. ADYNOVATE is used on-demand to control bleeding in patients 12 years of age and older with hemophilia A. ADYNOVATE can reduce the number of bleeding episodes when used regularly (prophylaxis). ADYNOVATE is not used to treat von Willebrand disease. Who should not use ADYNOVATE? You should not use ADYNOVATE if you: Are allergic to mice or hamster protein Are allergic to any ingredients in ADYNOVATE or ADVATE Tell your healthcare provider if you are pregnant or breastfeeding because ADYNOVATE may not be right for you. How should I use ADYNOVATE? ADYNOVATE is given directly into the bloodstream. You may infuse ADYNOVATE at a hemophilia treatment center, at your healthcare provider's office or in your home. You should be trained on how to do infusions by your healthcare provider or hemophilia treatment center. Many people with hemophilia A learn to infuse their ADYNOVATE by themselves or with the help of a family member. Your healthcare provider will tell you how much ADYNOVATE to use based on your individual weight, level of physical activity, the severity of your hemophilia A, and where you are bleeding. Reconstituted product (after mixing dry product with wet diluent) must be used within 3 hours and cannot be stored or refrigerated. Discard any ADYNOVATE left in the vial at the end of your infusion as directed by your healthcare professional. You may have to have blood tests done after getting ADYNOVATE to be sure that your blood level of factor VIII is high enough to clot your blood. Call your healthcare provider right away if your bleeding does not stop after taking ADYNOVATE. What should I tell my healthcare provider before I use ADYNOVATE? You should tell your healthcare provider if you: Have or have had any medical problems. Take any medicines, including prescription and non-prescription medicines, such as overthe- counter medicines, supplements or herbal remedies. Have any allergies, including allergies to mice or hamsters. Are breastfeeding. It is not known if ADYNOVATE passes into your milk and if it can harm your baby. Are pregnant or planning to become pregnant.  It is not known if ADYNOVATE may harm your unborn baby. Have been told that you have inhibitors to factor VIII (because ADYNOVATE may not work for you). What are the possible side effects of ADYNOVATE? You can have an allergic reaction to ADYNOVATE. Call your healthcare provider right away and stop treatment if you get a rash or hives, itching, tightness of the throat, chest pain or tightness, difficulty breathing, lightheadedness, dizziness, nausea or fainting. The common side effect of ADYNOVATE is headache and nausea. Tell your healthcare provider about any side effects that bother you or do not go away. These are not all the possible side effects with ADYNOVATE. You can ask your healthcare provider for information that is written for healthcare professionals. What are the ADYNOVATE dosage strengths? ADYNOVATE comes in four different dosage strengths: 250 International Units (IU), 500 IU, 1000 IU, and 2000 IU. The actual strength will be imprinted on the label and on the box. The four different strengths are color coded, as follows: Dosage strength of approximately 250 International Units per vial (200-400 IU/vial) Dosage strength of approximately 500 International Units per vial (401-800 IU/vial) Dosage strength of approximately 1000 International Units per vial (801-1250 IU/vial) Dosage strength of approximately 2000 International Units per vial (1251-2500 IU/vial) Always check the actual dosage strength printed on the label to make sure you are using the strength prescribed by your healthcare provider. Always check the expiration date printed on the box. Do not use the product after the expiration date printed on the box. How do I store ADYNOVATE? Do not freeze. Store at refrigerated temperature 2°C to 8°C (36°F to 46°F). May store at room temperature not to exceed 30°C (86°F) for up to 1 month. Write the date on the carton when ADYNOVATE is removed from refrigeration. After storage at room temperature, do not return product back to the refrigerator. Do not use beyond the expiration date printed on the carton or vial. Store vials in their original box and protect them from extreme exposure to light. What else should I know about ADYNOVATE and Hemophilia A? Your body may form inhibitors to Factor VIII. An inhibitor is part of the body's normal defense system. If you form inhibitors, it may stop ADYNOVATE from working properly. Consult with your healthcare provider to make sure you are carefully monitored with blood tests for the development of inhibitors to Factor VIII. Medicines are sometimes prescribed for purposes other than those listed here. Do not use ADYNOVATE for a condition for which it is not prescribed. Do not share ADYNOVATE with other people, even if they have the same symptoms that you have. Instructions for Use ADYNOVATE [Antihemophilic Factor (Recombinant), PEGylated] (For intravenous use only) Do not attempt to do an infusion to yourself unless you have been taught how by your healthcare provider or hemophilia center. Step-by-step instructions for reconstituting ADYNOVATE are found at the end of this leafl et. Always follow the specific instructions given by your healthcare provider. The steps listed below are general guidelines for using ADYNOVATE. If you are unsure of the procedures, please call your healthcare provider before using. Call your healthcare provider right away if bleeding is not controlled after using ADYNOVATE. Your healthcare provider will prescribe the dose that you should take. Reconstituted product (after mixing dry product with wet diluent) must be used within 3 hours and cannot be stored or refrigerated. Your healthcare provider may need to take blood tests from time to time. Talk to your healthcare provider before traveling. Plan to bring enough ADYNOVATE for your treatment during this time. Dispose of all materials, including any leftover reconstituted ADYNOVATE product, in an appropriate container. 1. Prepare a clean fl at surface and gather all the materials you will need for the infusion. Check the expiration date, and let the vials with the ADYNOVATE concentrate and the Sterile Water for Injection, USP (diluent) warm up to room temperature. Wash your hands and put on clean exam gloves. If infusing yourself at home, the use of gloves is optional. If you are using more than one vial of ADYNOVATE, make sure you mix each vial of ADYNOVATE with the Sterile Water for Injection, USP that is provided in the box. Inspect the contents of the product and diluent vials. The ADYNOVATE powder should be white to off-white in color and the diluent should not contain particles. Do not use if discoloration or particles are seen. 2. Remove caps from the ADYNOVATE concentrate and diluents vials to expose the centers of the rubber stoppers. 3. Disinfect the stoppers with a sterile alcohol prep pad (or other suitable solution suggested by your healthcare provider or hemophilia center) by rubbing the stoppers firmly for several seconds and allow them to dry prior to use. Place the vials on a flat surface. 4. Open the BAXJECT II Hi-Flow device package by completely peeling away the lid, without touching the inside of the package. Do not remove the BAXJECT II Hi-flow device from the package. 5. Turn the package with the BAXJECT II Hi-Flow device upside down and place it over the top of the diluent vial. Fully insert the clear plastic spike of the device into the center of the diluent vial's stopper by pushing straight down. Grip the package at its edge and lift it off the device. Be careful not to touch the purple plastic spike. Do not remove the blue cap from the BAXJECT II Hi-Flow device. The diluent vial now has the BAXJECT II Hi-Flow device connected to it and is ready to be connected to the ADYNOVATE vial. 6. To connect the diluent vial to the ADYNOVATE vial, turn the diluent vial over and place it on top of the vial containing ADYNOVATE concentrate. Fully insert the purple plastic spike into the ADYNOVATE vial's stopper by pushing straight down. Diluent will flow into the ADYNOVATE vial. This should be done right away to keep the liquid free of germs. 7. Swirl the connected vials gently and continuously until the ADYNOVATE is completely dissolved. Do not shake. 8. Take off the blue cap from the BAXJECT II Hi-Flow device and connect the syringe. Use of a Luer-lock syringe is recommended. Be careful to not inject air. 9. Turn over the connected vials so that the ADYNOVATE vial is on top. Draw the ADYNOVATE solution into the syringe by pulling back the plunger slowly. Disconnect the syringe from the vials. Attach the infusion needle to the syringe using a winged (butterfly) infusion set, if available. Point the needle up and remove any air bubbles by gently tapping the syringe with your finger and slowly and carefully pushing air out of the syringe and needle. The ADYNOVATE solution should look clear and colorless. If not, do not use it and notify Baxalta immediately. 10. If you are using more than one vial of ADYNOVATE, the contents of more than one vial may be drawn into the same syringe (Following Steps 1-9). You will need a separate BAXJECT II Hi-Flow device to mix each additional vial of ADYNOVATE. Apply a tourniquet and get the injection site ready by wiping the skin well with a sterile alcohol prep pad (or other suitable solution suggested by your healthcare provider or hemophilia center). 11. Insert the needle into the vein and remove the tourniquet. Slowly infuse the ADYNOVATE. Do not infuse any faster than 10 mL per minute. 12. Take the needle out of the vein and use sterile gauze to put pressure on the infusion site for several minutes. 13. Do not recap the needle. Place it with the used syringe in a hard-walled Sharps container for proper disposal. 14. Remove the peel-off label from the ADYNOVATE vial and place it in your logbook. Clean any spilled blood with a freshly prepared mixture of 1 part bleach and 9 parts water, soap and water, or any household disinfecting solution. 15. Dispose of the used vials and BAXJECT II Hi-Flow device in your hard-walled sharps container without taking them apart. Do not dispose of these supplies in ordinary household trash. Important: Contact your healthcare provider or local hemophilia treatment center if you experience any problems.

OVERDOSE No information provided. CONTRAINDICATIONS ADYNOVATE is contraindicated in patients who have had prior anaphylactic reaction to ADYNOVATE, to the parent molecule (ADVATE), mouse or hamster protein, or excipients of ADYNOVATE (e.g. Tris, mannitol, trehalose, glutathione, and/or polysorbate 80).

SIDE EFFECTS Common adverse reactions ( ≥ 1% of subjects) reported in the clinical studies were headache and nausea. Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in clinical trials of another drug and may not refl ect the rates observed in practice. The safety of ADYNOVATE was evaluated in 169 previously treated patients (PTPs) with severe hemophilia A (factor VIII less than 1% of normal), who received at least one dose of ADYNOVATE in 2 multi-center, prospective, open label clinical studies and 3 ongoing clinical studies. The median duration of participation per subject was 333 (min-max: 1-593) days and the median number of exposure days to ADYNOVATE per subject was 96 (min-max: 1-170). Table 2 lists the adverse reactions reported during clinical studies. Table 2: Adverse Reactions Reported for ADYNOVATE MedDRA System Organ Class MedDRA Preferred Term Number of Subjects n (%) (N=169) Percent of Infusion (N=13579) Gastrointestinal Disorders 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% No events of hypersensitivity were reported. Two cases of acute pancreatitis, with no precipitating cause identified in one case, were reported in adults during an extension study of the clinical trial which evaluated 137 subjects. Administration of ADYNOVATE continued and both cases resolved. Immunogenicity The risk of the development of factor VIII inhibitors with the use of ADYNOVATE was evaluated in 2 completed and 3 ongoing clinical trials. Study subjects consisted of adult (n= 143 with ≥ prior 150 EDs) and pediatric PTPs [( < 6 years of age with ≥ 50 prior EDs (n= 3), ≥ 6 years of age with ≥ 150 prior EDs (n= 23)]. In 120 adult and pediatric PTPs who were treated for at least 50 exposure days with ADYNOVATE, the factor VIII inhibitor frequency was 0 (95% CI of 0 to 0.03). None of the 169 individual subjects who received at least one infusion of ADYNOVATE developed neutralizing antibodies to factor VIII. Immunogenicity also was evaluated by measuring the development of binding IgG and IgM antibodies against factor VIII, PEGylated (PEG)-factor VIII, PEG and Chinese hamster ovary (CHO) protein using validated ELISA assays. None of the 169 treated subjects with at least one infusion of ADYNOVATE developed a persistent binding antibody response to any of these antigens. Thirteen subjects in total showed pre-existing antibodies to factor VIII (n=1), PEG-factor VIII (n=12) and/or PEG (n=3) prior to the first exposure to ADYNOVATE. Eight subjects who tested negative at screening developed transient IgG antibodies against factor VIII (n= 5), or PEG-FVIII (n= 3) at one or two consecutive study visits. Binding antibodies that were detected prior to exposure to ADYNOVATE or that transiently developed during the study could not be correlated to any impaired treatment efficacy, altered PK parameters, or adverse reactions. No subject had pre-existing or treatment-emergent antibodies to CHO protein. The detection of antibodies that are reactive to factor VIII is highly dependent on many factors, including: the sensitivity and specificity of the assay, sample handling, timing of sample collection, concomitant medications and underlying disease. For these reasons, comparison of the incidence of antibodies to ADYNOVATE with the incidence of antibodies to other products may be misleading. DRUG INTERACTIONS No information provided.

WARNINGS Included as part of the PRECAUTIONS section. 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 one-stage clotting assay to confirm the adequate factor VIII levels have been achieved and maintained [see DOSAGE AND ADMINISTRATION]. 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 levels. Patient Counseling Information Advise patients to: Read the FDA-approved patient labeling (PATIENT INFORMATION and Instructions for Use). Call their healthcare provider or go to the emergency department right away if a hypersensitivity reaction occurs. Early signs of hypersensitivity reactions may include rash, hives, itching, facial swelling, tightness of the chest, and wheezing. Advise patients to discontinue use of the product if these symptoms occur and seek immediate emergency treatment. Contact their healthcare provider or treatment facility for further treatment and/or assessment if they experience a lack of a clinical response to factor VIII therapy because this may be a sign of inhibitor development. Advise patients to consult with their physicians or healthcare provider prior to travel. While traveling, advise patients to bring an adequate supply of ADYNOVATE based on their current regimen of treatment.

Nonclinical Toxicology Carcinogenesis, Mutagenesis, Impairment Of Fertility Long-term studies in animals to evaluate the carcinogenic potential of ADYNOVATE or studies to determine the effects of ADYNOVATE on genotoxicity or fertility have not been performed. Use In Specific Populations Pregnancy Risk Summary There are no data with ADYNOVATE use in pregnant women to inform a drug-associated risk. Animal reproduction studies have not been conducted with ADYNOVATE. It is unknown whether ADYNOVATE can cause fetal harm when administered to a pregnant woman or can affect reproduction capacity. ADYNOVATE should be given to a pregnant woman only if clearly needed. In the U.S. general population, the estimated background risk of major birth defect and miscarriage in clinically recognized pregnancies is 2-4% and 15-20%, respectively. Lactation Risk Summary There is no information regarding the presence of ADYNOVATE in human milk, the effect on the breastfed infant, or the effects on milk production. The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for ADYNOVATE and any potential adverse effects on the breastfed infant from ADYNOVATE or from the underlying maternal condition. Pediatric Use The safety, efficacy, or pharmacokinetic profiles of ADYNOVATE have not been established in pediatric patients less than 12 years old. In the clinical trial, 25 adolescents aged 12 to less than 18 were included in the analysis. The safety, efficacy, and PK profile were comparable between adolescents and adults [see CLINICAL PHARMACOLOGY and Clinical Studies]. Geriatric Use Clinical studies of ADYNOVATE did not include subjects aged 65 and over.
