Helpful patient support tools for health care professionals

NovoSeven^® RT (coagulation Factor VIIa, recombinant) is a coagulation factor indicated for:

• Treatment of bleeding episodes and perioperative management in adults and children with hemophilia A or B with inhibitors, congenital Factor VII (FVII) deficiency, and Glanzmann’s thrombasthenia with refractoriness to platelet transfusions, with or without antibodies to platelets
• Treatment of bleeding episodes and perioperative management in adults with acquired hemophilia

• Serious arterial and venous thrombotic events have been reported in clinical trials and postmarketing surveillance
• Patients with congenital hemophilia receiving concomitant treatment with aPCCs (activated prothrombin complex concentrates), older patients particularly with acquired hemophilia and receiving other hemostatic agents, and patients with a history of cardiac and vascular disease may have an increased risk of developing thrombotic events
• Hypersensitivity reactions, including anaphylaxis, can occur with NovoSeven^® RT. Patients with a known hypersensitivity to mouse, hamster, or bovine proteins may be at a higher risk of hypersensitivity reactions. Discontinue infusion and administer appropriate treatment when hypersensitivity reactions occur
• Factor VII deficient patients should be monitored for prothrombin time (PT) and factor VII coagulant activity (FVII:C). If FVII:C fails to reach the expected level, or PT is not corrected, or bleeding is not controlled after treatment with the recommended doses, antibody formation may be suspected and analysis for antibodies should be performed
• Laboratory coagulation parameters (PT/INR, aPTT, FVII:C) have shown no direct correlation to achieving hemostasis

• The most common and serious adverse reactions in clinical trials are thrombotic events. Thrombotic adverse reactions following the administration of NovoSeven^® RT in clinical trials occurred in 4% of patients with acquired hemophilia and 0.2% of bleeding episodes in patients with congenital hemophilia

• Thrombosis may occur if NovoSeven^® RT is administered concomitantly with Coagulation Factor XIII

Please see NovoSeven^® RT Prescribing Information, including Boxed Warning.

Alhemo^® (concizumab-mtci) injection 60 mg, 150 mg, or 300 mg is indicated for routine prophylaxis to prevent or reduce the frequency of bleeding episodes in adult and pediatric patients 12 years of age and older with hemophilia A or B with or without factor VIII or IX inhibitors.

• Alhemo^® is contraindicated in patients with a history of known serious hypersensitivity to Alhemo^® or its ingredients

• Thromboembolic Events (TEs): Venous and arterial TEs were reported in 1.9% of patients (6/320) who also had multiple risk factors, including the use of high doses or prolonged treatment with factor products or bypassing agents (2 of 6 patients). Risk factors for TEs may also include conditions in which tissue factor is overexpressed (eg, atherosclerotic disease, crush injury, cancer, disseminated intravascular coagulation, thrombotic microangiopathy, or septicemia). Inform patients about and monitor them for signs and symptoms of TEs. In case of suspicion of TEs, discontinue Alhemo^® and initiate further investigations and management strategies
• Hypersensitivity Reactions: Alhemo^® is contraindicated in patients with a history of known serious hypersensitivity to Alhemo^® or its ingredients. Hypersensitivity reactions, including erythema, rash, pruritus, and abdominal pain, have occurred in patients treated with Alhemo^®. One patient (<1%) experienced anaphylaxis, which resolved after treatment with antihistamines and corticosteroids. Instruct patients of the signs of acute hypersensitivity reactions and to contact their healthcare provider for mild reactions and to seek urgent medical attention for moderate to severe reactions. Discontinue Alhemo^® if severe hypersensitivity symptoms occur, and initiate medical management
• Increased Laboratory Values of Fibrin D-dimer and Prothrombin Fragment 1.2: Increased levels of fibrin D-dimer and prothrombin fragment 1.2 were seen in 29 (9.1%) and 26 (8.1%) patients, respectively, which is positively correlated with the plasma concentration of concizumab-mtci, indicating a hemostatic effect. For patients taking Alhemo^®, these coagulation biomarkers may not be reliable predictive markers for clinical decision-making with suspicion of thrombosis, such as deep vein thrombosis and pulmonary embolism

• The most frequently reported adverse reactions (≥5%) were injection site reactions, headache, and urticaria
• Serious adverse reactions were reported in 6.1% of patients with inhibitors who received Alhemo^®. Permanent discontinuation of Alhemo^® occurred in 1 patient due to a renal infarct and dosage interruptions of Alhemo^® occurred in 1 patient (3%) and was a hypersensitivity reaction

• Breakthrough Bleeding Treatment: Take appropriate precautions when treating breakthrough bleeding events in patients receiving Alhemo^® prophylaxis and FVIII or FIX or a bypassing agent (eg, rFVIIa or aPCC). For mild and moderate bleeds, the lowest approved dose in the approved product labeling is recommended. For aPCC, a maximum dose of 100 units/kg within 24 hours is recommended. For severe bleeds, follow the dosing instructions in the approved labeling based on clinical judgment

Esperoct^® [antihemophilic factor (recombinant), glycopegylated-exei] is indicated for use in adults and children with hemophilia A for on-demand treatment and control of bleeding episodes, perioperative management of bleeding, and routine prophylaxis to reduce the frequency of bleeding episodes

• Esperoct^® is not indicated for the treatment of von Willebrand disease

• Do not use in patients who have known hypersensitivity to Esperoct^® or its components, including hamster proteins

• Hypersensitivity reactions, including anaphylaxis, may occur. Should hypersensitivity reactions occur, discontinue Esperoct^® and administer appropriate treatment
• Development of neutralizing antibodies (inhibitors) has occurred. Perform an assay that measures Factor VIII inhibitor concentration if bleeding is not controlled with the recommended dose of Esperoct^® or if the expected plasma Factor VIII activity levels are not attained
• Temporary decrease in Factor VIII incremental recovery (IR) has been observed after Esperoct^® infusion, within the first 5 exposure days, in previously untreated patients (PUPs) <6 years of age. During the decreased IR period, these subjects may have an increased bleeding tendency. If bleeding is not controlled with the recommended dose of Esperoct^® and/or the expected Factor VIII activity levels are not attained and Factor VIII inhibitors are not detected, consider adjusting the dose, dosing frequency, or discontinuing Esperoct^®

• The most frequently reported adverse reactions in clinical trials (≥1%) were rash, redness, itching (pruritus), and injection site reactions. Additional frequently reported adverse reactions (≥1%) in PUPs included Factor VIII inhibition and hypersensitivity.

Please see Esperoct^® Prescribing Information.

Novoeight^® (antihemophilic factor, recombinant) is indicated for use in adults and children with hemophilia A for on-demand treatment and control of bleeding episodes, perioperative management, and routine prophylaxis to reduce the frequency of bleeding episodes.

• Novoeight^® is not indicated for the treatment of von Willebrand disease

• Do not use in patients who have had life-threatening hypersensitivity reactions, including anaphylaxis, to Novoeight^® or its components, including hamster proteins

• Anaphylaxis and severe hypersensitivity reactions are possible. Patients may develop hypersensitivity to hamster proteins, which are present in trace amounts in the product. Should symptoms occur, discontinue Novoeight^® and administer appropriate treatment
• Development of activity-neutralizing antibodies (inhibitors) may occur. Previously untreated patients (PUPs) are at greatest risk for inhibitor development with all factor VIII products. Inhibitors have been reported following administration of Novoeight^® in PUPs. If expected plasma factor VIII activity levels are not attained, or if bleeding is not controlled with an appropriate dose, perform testing for factor VIII inhibitors

• The most frequently reported adverse reactions (≥1%) were inhibitors in Previously Untreated Patients (PUPs), injection site reactions, and pyrexia.

Please see Novoeight^® Prescribing Information.

Rebinyn^®, Coagulation Factor IX (Recombinant), GlycoPEGylated, is a recombinant DNA derived coagulation Factor IX concentrate indicated for use in adults and children with hemophilia B (congenital Factor IX deficiency) for on demand treatment and control of bleeding episodes, perioperative management of bleeding, and routine prophylaxis to reduce the frequency of bleeding episodes.

Limitations of Use: Rebinyn^® is not indicated for immune tolerance induction in patients with hemophilia B.

• Rebinyn^® is contraindicated in patients with a known hypersensitivity to Rebinyn^® or its components, including hamster proteins.

• Hypersensitivity Reactions: Allergic-type hypersensitivity reactions, including anaphylaxis, have occurred with Rebinyn^®. Signs may include angioedema, chest tightness, difficulty breathing, wheezing, urticaria, and itching. Discontinue Rebinyn^® if allergic- or anaphylactic-type reactions occur and initiate appropriate treatment. 
• Inhibitors: The formation of inhibitors (neutralizing antibodies) to Factor IX has occurred following Rebinyn^®. If expected plasma factor IX activity levels are not attained, or if bleeding is not controlled as expected with the administered dose, perform an assay that measures Factor IX inhibitor concentration. Monitor all patients using clinical observations and laboratory tests for the development of inhibitors. Factor IX activity assay results may vary with the type of activated partial thromboplastin time reagent used.
• Thrombotic Events: The use of Factor IX-containing products has been associated with thromboembolic complications. Monitor for thrombotic and consumptive coagulopathy when administering Rebinyn^® to patients with liver disease, post-operatively, to newborn infants, or to patients at risk of thrombosis or disseminated intravascular coagulation (DIC). 
• Nephrotic Syndrome: Nephrotic syndrome has been reported following immune tolerance induction therapy with Factor IX products in hemophilia B patients with Factor IX inhibitors, often with a history of allergic reactions to Factor IX. The safety and efficacy of using Rebinyn^® for immune tolerance induction have not been established.

• The most common adverse reactions reported in previously treated patients in clinical trials (≥1%) were itching and injection site reactions. The most common adverse reactions (≥1%) in previously untreated patients reported in clinical trials were rash, FIX inhibitors, hypersensitivity, itching, injection site reaction, and anaphylactic reaction.
• Animals administered Rebinyn^® showed accumulation of PEG in the choroid plexus, pituitary, circumventricular organs, and cranial motor neurons. The potential clinical implications of these animal findings are unknown. Consider whether the patient is vulnerable to cognitive impairment, such as infants and children who have developing brains, and patients who are cognitively impaired.

Tretten^® (Coagulation Factor XIII A-Subunit [Recombinant]) is indicated for routine prophylaxis of bleeding in patients with congenital Factor XIII A-subunit deficiency.

Tretten^® is not for use in patients with congenital Factor XIII B-subunit deficiency.

Tretten^® is contraindicated in patients with hypersensitivity to the active substance or to any of the excipients.

Tretten^® may cause allergic reactions. If signs or symptoms of anaphylaxis or hypersensitivity reactions (including urticaria, rash, tightness of the chest, wheezing, hypotension) occur, discontinue immediately and institute appropriate treatment.

Thromboembolic complications may occur. Monitor patients with conditions that predispose to thrombosis for signs and symptoms of thrombosis after administration of Tretten^®.

Inhibitory antibodies may occur with Tretten^®. Patients with inhibitory antibodies may manifest as an inadequate response to treatment. If expected plasma FXIII activity levels are not attained, or if breakthrough bleeding occurs while receiving prophylaxis, perform an assay that measures FXIII inhibitory antibody concentrations.

The most common adverse reactions reported in clinical trials (≥1%) were headache, pain in the extremities, pain at injection site, and increase in fibrin D dimer levels. 

Thrombosis may occur if Tretten^® is administered concomitantly with Factor VIIa.

There are no adequate and well-controlled studies using Tretten^® in pregnant women to determine whether there is a drug-associated risk. Animal reproduction studies have not been conducted with Tretten^®.
