Results from studies with previously treated patients:
and thrombotic events1,2,a
The safety of Rebinyn® has been studied in clinical trials, with 0 inhibitors and thrombotic events confirmed in 115 previously treated males over 8801 exposure days.1-3,a
- Adverse reactions include hypersensitivity (1%), itching (3%), and injection-site reactions (4%)1,a
- Formation of inhibitors and thrombotic complications have been associated with FIX treatment. Monitor patients for the development of inhibitors and signs of thrombosis1
aIdentified in 115 previously treated patients who were treated with Rebinyn® in clinical studies. A previously treated patient was defined as a subject with a history of at least 150 exposure days to other FIX products (adolescent/adult subjects) or 50 exposure days to other FIX products (pediatric subjects) and no history of inhibitors. There were a total of 8801 exposure days, equivalent to 170 patient-years. A total of 40 patients (35%) were treated for more than 2 years.1
Manufactured to help ensure safety and purity
Rebinyn® is a recombinant factor IX treatment made without human blood, plasma, or proteins.
Recombinant factor IX products are recommended as a treatment of choice for patients with hemophilia B.4
What are the latest recommendations?
The National Hemophilia Foundation’s Medical and Scientific Advisory Council (MASAC) recommends recombinant factor IX products as a treatment of choice for patients with hemophilia B.4
Animals administered repeat doses of Rebinyn® showed accumulation of PEG in the choroid plexus. The potential clinical implications of these animal findings are unknown.

Selected Important Safety Information for Rebinyn®
Contraindications
- Rebinyn® is contraindicated in patients with a known hypersensitivity to Rebinyn® or its components, including hamster proteins.
Warnings and Precautions
Hypersensitivity reactions, including anaphylaxis, may occur. 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.
Indications and Usage
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 for on demand treatment and control of bleeding episodes and perioperative management of bleeding.
Limitations of Use: Rebinyn® is not indicated for routine prophylaxis or for immune tolerance induction in patients with hemophilia B.
Important Safety Information
Contraindications
- Rebinyn® is contraindicated in patients with a known hypersensitivity to Rebinyn® or its components, including hamster proteins.
Warnings and Precautions
- Hypersensitivity reactions, including anaphylaxis, may occur. 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.
- Development of neutralizing antibodies (inhibitors) to Factor IX may occur. Monitor patients for development of factor IX inhibitors if bleeding is not controlled with the recommended dose of Rebinyn® or if expected Factor IX activity plasma levels are not attained. Factor IX activity assay results may vary with the type of activated partial thromboplastin time reagent used.
- The use of Factor IX-containing products has been associated with thrombotic 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 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.
Adverse Reactions
- The most common adverse reactions reported in clinical trials (≥1%) were itching and injection site reactions.
- Animals administered repeat doses of Rebinyn® showed accumulation of PEG in the choroid plexus. The potential clinical implications of these animal findings are unknown.
