U.S. FDA Approves CSL Behring’s IDELVION® -- The First and Only Hemophilia B Therapy with Up to 14-day Dosing Intervals
CSL Behring announced today that the U.S. Food and Drug Administration (FDA) has approved IDELVION®
[Coagulation Factor IX (Recombinant), Albumin Fusion Protein], its novel, long-acting albumin fusion protein linking recombinant coagulation factor IX with recombinant albumin for the treatment of hemophilia B. IDELVION
is the first and only factor IX therapy that delivers high-level protection with up to 14-day dosing in appropriate patients. This dosing interval has been achieved while maintaining high levels of factor activity, above 5 percent over 14 days at 75 IU/kg. This reduces the monthly number of units needed for prophylaxis therapy.

Turner, former President of CSL Behring and former Chief Operating Officer of CSL group, will substantially increase CSL Behring’s total immunoglobulin (Ig) therapy production capabilities.
Important Safety Information for AFSTYLA
AFSTYLA®, Antihemophilic Factor (Recombinant), Single Chain, is contraindicated in patients who have had life-threatening hypersensitivity reactions to AFSTYLA or its excipients, or to hamster proteins.
AFSTYLA is for intravenous use only. AFSTYLA can be self-administered or administered by a caregiver with training and approval from a healthcare provider or hemophilia treatment center. Higher and/or more frequent dosing may be needed for patients under 12 years of age.
Hypersensitivity reactions, including anaphylaxis, are possible. Advise patients to immediately report symptoms of a hypersensitivity reaction. If symptoms occur, discontinue AFSTYLA and administer appropriate treatment.
Development of Factor VIII (FVIII) neutralizing antibodies (inhibitors) can occur. If expected FVIII activity levels are not attained or bleeding is not controlled with appropriate dose, perform an assay to measure FVIII inhibitor concentration.
Monitor plasma FVIII activity using a chromogenic assay or one-stage clotting assay. If one-stage clotting assay is used, multiply result by a conversion factor of 2 to determine FVIII activity level.
The most common adverse reactions reported in clinical trials (>0.5%) were dizziness and hypersensitivity.
Indications for AFSTYLA
AFSTYLA is indicated in adults and children with hemophilia A (congenital Factor VIII deficiency) for:
- On-demand treatment and control of bleeding episodes
- Routine prophylaxis to reduce frequency of bleeding episodes
- Perioperative management of bleeding
AFSTYLA is not indicated for the treatment of von Willebrand disease.
Please see full prescribing information for AFSTYLA.
Important Safety Information for IDELVION
IDELVION®, Coagulation Factor IX (Recombinant), Albumin Fusion Protein (rFIX-FP), is contraindicated in patients who have had life-threatening hypersensitivity to the product or its components, including hamster proteins.
IDELVION is for intravenous use only. IDELVION can be self-administered or administered by a caregiver with training and approval from a healthcare provider or hemophilia treatment center. Higher dose per kilogram body weight or more frequent dosing may be needed for pediatric patients.
Hypersensitivity reactions, including anaphylaxis, are possible. Advise patients who self-administer to immediately report symptoms of hypersensitivity, including angioedema, chest tightness, hypotension, generalized urticaria, wheezing, and dyspnea. If symptoms occur, discontinue IDELVION and administer appropriate treatment.
Development of neutralizing antibodies (inhibitors) to IDELVION may occur. If expected Factor IX activity plasma levels are not attained or bleeding is not controlled with appropriate dose, perform an assay to measure Factor IX inhibitor concentration. Factor IX activity assay results may vary with the type of activated partial thromboplastin time reagent used.
Thromboembolism (eg, pulmonary embolism, venous thrombosis, and arterial thrombosis) can occur when using Factor IX-containing products. In addition, nephrotic syndrome has been reported following immune tolerance induction in hemophilia B patients with Factor IX inhibitors and allergic reactions to Factor IX.
The most common adverse reaction (incidence ≥1%) reported in clinical trials was headache.
Indications for IDELVION
IDELVION is indicated in children and adults with hemophilia B (congenital Factor IX deficiency) for:
- On-demand control and prevention of bleeding episodes
- Perioperative management of bleeding
- Routine prophylaxis to prevent or reduce the frequency of bleeding episodes
IDELVION is not indicated for induction of immune tolerance in patients with hemophilia B.
Please see full prescribing information for IDELVION.
Important Safety Information for Berinert
Berinert®, C1 Esterase Inhibitor (Human), is a plasma-derived concentrate of C1 Esterase Inhibitor (Human), indicated for the treatment of acute abdominal, facial or laryngeal attacks of hereditary angioedema (HAE) in adult and pediatric patients. The safety and efficacy of Berinert for prophylactic therapy have not been established.
Berinert is contraindicated in individuals with a history of life-threatening systemic reactions to C1 esterase inhibitor preparations (including anaphylaxis).
Monitor patients for early signs of allergic or hypersensitivity reactions (including hives, generalized urticaria, chest tightness, wheezing, hypotension, and anaphylaxis). If hypersensitivity is suspected, immediately discontinue administration of Berinert and initiate appropriate treatment. Epinephrine should be immediately available for treatment of acute severe hypersensitivity reactions.
Serious arterial and venous thromboembolic (TE) events have been reported following administration of recommended doses of C1 Esterase Inhibitor (Human) products to patients with HAE. Risk factors may include presence of an indwelling venous catheter/access device; prior history of thrombosis; underlying atherosclerosis; use of oral contraceptives or certain androgens; morbid obesity; and immobility. Weigh benefits/risks before administering to patients with known risk factors for TE events and closely monitor such patients during and after Berinert administration. TE events also have been reported with C1 Esterase Inhibitor (Human) products when used for unapproved indications at higher than recommended doses.
Appropriately trained patients may self-administer Berinert upon recognition of an HAE attack. Advise patients to seek medical attention immediately following selfadministration for laryngeal attacks, and to seek medical attention if progress of any attack makes them unable to properly prepare or administer dose of Berinert.
Berinert is derived from human plasma. The risk of transmission of infectious agents, including viruses and theoretically, the agents of Creutzfeldt-Jakob Disease (CJD) and its variant form (vCJD), cannot be completely eliminated.
The most serious adverse reaction reported in subjects who received Berinert in clinical studies was an increase in severity of pain associated with HAE. Dysgeusia was the most common adverse reaction reported in over 4% of subjects and more frequently than in the placebo group.
Berinert has not been evaluated in pregnant women or nursing mothers, and should be used only if clearly needed. In clinical trials, the half-life of Berinert was shorter and clearance was faster in children than in adults; the clinical implication of this difference is not known.
Please see full prescribing information for Berinert, including the patient product information.
Important Safety Information for Privigen
Immune Globulin Intravenous (Human), 10% Liquid, Privigen®, is indicated as replacement therapy for patients with primary immunodeficiency (PI) associated with defects in humoral immunity, including but not limited to common variable immunodeficiency (CVID), X-linked agammaglobulinemia, congenital agammaglobulinemia, Wiskott-Aldrich syndrome, and severe combined immunodeficiencies. Privigen is also indicated to raise platelet counts in patients with chronic immune thrombocytopenic purpura (ITP).
WARNING: THROMBOSIS, RENAL DYSFUNCTION AND ACUTE RENAL FAILURE
- Thrombosis may occur with immune globulin products, including Privigen. Risk factors may include advanced age, prolonged immobilization, hypercoagulable conditions, history of venous or arterial thrombosis, use of estrogens, indwelling vascular catheters, hyperviscosity, and cardiovascular risk factors.
- Renal dysfunction, acute renal failure, osmotic nephrosis, and death may occur with the administration of human immune globulin intravenous (IGIV) products in predisposed patients. Renal dysfunction and acute renal failure occur more commonly in patients receiving IGIV products that contain sucrose. Privigen does not contain sucrose.
- For patients at risk of thrombosis, renal dysfunction or renal failure, administer Privigen at the minimum dose and infusion rate practicable. Ensure adequate hydration in patients before administration. Monitor for signs and symptoms of thrombosis and assess blood viscosity in patients at risk for hyperviscosity.
See full prescribing information for complete boxed warning.
Privigen is contraindicated in patients with history of anaphylactic or severe systemic reaction to human immune globulin, in patients with hyperprolinemia, and in IgA-deficient patients with antibodies to IgA, who have had hypersensitivity reactions. Patients with IgA deficiency and antibodies to IgA are at greater risk of severe hypersensitivity and anaphylactic reactions.
In patients at risk for developing acute renal failure, monitor urine output and renal function, including blood urea nitrogen and serum creatinine; discontinue if renal function deteriorates. Ensure that patients with preexisting renal insufficiency or otherwise predisposed are not volume-depleted and administer Privigen at the minimum rate of infusion practicable.
Thrombosis might occur with Privigen, even in the absence of known risk factors. Patients could also experience hyperproteinemia, increased serum viscosity, or hyponatremia; infrequently, aseptic meningitis syndrome (AMS) may occur—more frequently with high doses (2 g/kg) and/or rapid infusion.
Hemolysis, either intravascular or due to enhanced red blood cell sequestration, can develop subsequent to treatment. Risk factors include non-O blood group, underlying inflammation, and high doses. Closely monitor patients for hemolysis and hemolytic anemia. Consider the relative risks and benefits before prescribing high-dose regimen for chronic ITP in patients at increased risk of thrombosis, hemolysis, acute kidney injury or volume overload. Monitor patients for pulmonary adverse reactions and signs of transfusion-related acute lung injury (TRALI).
Privigen is derived from human plasma. The risk of transmission of infectious agents, including viruses and, theoretically, the Creutzfeldt-Jakob disease (CJD) agent, cannot be completely eliminated.
In clinical studies of patients being treated with Privigen for PI, the most common adverse reactions observed in >5% of subjects were headache, fatigue, nausea, chills, vomiting, back pain, pain, elevated body temperature, abdominal pain, diarrhea, cough, stomach discomfort, chest pain, joint swelling/effusion, influenza-like illness, pharyngolaryngeal pain, urticaria, and dizziness. Serious adverse reactions were hypersensitivity, chills, fatigue, dizziness, and increased body temperature.
In clinical studies of patients being treated with Privigen for chronic ITP, the most common adverse reactions seen in >5% of subjects were headache, elevated body temperature, positive DAT, anemia, nausea, epistaxis, vomiting, increases in conjugated and unconjugated bilirubin, decreased hematocrit, and increased blood lactate dehydrogenase. A serious adverse reaction was aseptic meningitis syndrome (AMS).
Treatment with Privigen might interfere with a patient’s response to live virus vaccines and could lead to misinterpretation of serologic testing. Use in pregnant women only if clearly needed. In patients over 65 or in any patient at risk of developing renal insufficiency, do not exceed recommended dose and infuse Privigen at the minimum rate practicable.
