Use our interactive PK Modeling Tool to predict FIX activity of Rebinyn® compared with standard half-life (SHL) factor IX products. See plasma activity, WFH target factor IX levels, total dosage, and total infusions required for a range of bleed types: mild to moderate, severe, surgical use, or intracranial hemorrhages.

WFH=World Federation of Hemophilia

COMPARED WITH SHL, A SINGLE DOSE OF REBINYN® WAS PREDICTED TO CONTROL A MILD TO MODERATE BLEED

A single 40 IU/kg dose of Rebinyn®, was predicted to provide FIX levels above 40% for an average of 23 hours using PK simulations.1

1 dose of Rebinyn® vs 2 doses of SHL rFIX or pdFIX were required to maintain the same WFH target FIX activity level.1

WFH=World Federation of Hemophilia

COMPARED WITH SHL, A SINGLE DOSE OF REBINYN® WAS PREDICTED TO CONTROL A SEVERE BLEED

A single 80 IU/kg dose of Rebinyn® was predicted to provide FIX levels above 50% for an average of 3 days using PK simulations.1

1 dose of Rebinyn® vs 6 doses of SHL rFIX or pdFIX were required to maintain the same WFH target FIX activity level.1

WFH=World Federation of Hemophilia

COMPARED WITH SHL, AN INITIAL DOSE OF REBINYN® WAS PREDICTED TO MAINTAIN FIX LEVELS IN SURGERY

A single 80 IU/kg dose of Rebinyn®, followed by two 40 IU/kg doses, was predicted to maintain target FIX levels for a 2-week postoperative period using PK simulations.1

3 doses of Rebinyn® vs 17 doses of SHL rFIX or pdFIX were required to maintain the same WFH target FIX activity level.1

WFH=World Federation of Hemophilia

COMPARED WITH SHL, FEWER DOSES OF REBINYN® WERE PREDICTED TO CONTROL FIX LEVELS IN INTRACRANIAL HEMORRHAGE

A single 80 IU/kg dose of Rebinyn®, followed by four 40 IU/kg doses, was predicted to maintain target FIX levels for a 3-week postoperative period using PK simulations.1

5 doses of Rebinyn® vs 28 doses of SHL rFIX or pdFIX were required to maintain the same WFH target FIX activity level.1

Use our interactive PK Modeling Tool to predict FIX activity of Rebinyn® compared with an extended half-life (EHL) factor IX product. See plasma activity, WFH target factor IX levels, total dosage, and total infusions required for a range of bleed types: severe, surgical use, or life-threatening bleeds. 

WFH=World Federation of Hemophilia

COMPARED WITH EHL rFIXFc, A SINGLE DOSE OF REBINYN® WAS PREDICTED TO CONTROL A SEVERE BLEED

A single 80 IU/kg dose of Rebinyn® was predicted to provide FIX levels above 50% for an average of ≈5 days using PK simulations.2

1 dose of Rebinyn® vs 4 doses of EHL rFIXFc were required to maintain the same WFH target FIX activity level.2

WFH=World Federation of Hemophilia

COMPARED WITH EHL rFIXFc, AN INITIAL DOSE OF REBINYN® WAS PREDICTED TO MAINTAIN FIX LEVELS IN SURGERY

A single 80 IU/kg dose of Rebinyn®, followed by two 40 IU/kg doses, was predicted to maintain target FIX levels for a 2-week postoperative period using PK simulations.2

3 doses of Rebinyn® vs 9 doses of EHL rFIXFc were required to maintain the same WFH target FIX activity level.2

WFH=World Federation of Hemophilia

COMPARED WITH EHL rFIXFc, FEWER DOSES OF REBINYN® WERE PREDICTED TO CONTROL FIX LEVELS IN LIFE-THREATENING BLEEDS

A single 80 IU/kg dose of Rebinyn®, followed by four 40 IU/kg doses, was predicted to maintain target FIX levels for a 3-week postoperative period using PK simulations.2

5 doses of Rebinyn® vs 11 doses of EHL rFIXFc were required to maintain the same WFH target FIX activity level.2

REBINYN® MAY REDUCE THE NEED FOR ADDITIONAL INFUSIONS1,2,a-c

Based on pharmacokinetic (PK) modeling, Rebinyn® required fewer infusions per episode when compared with SHL and EHL FIX products.

Estimated number of doses and amount of FIX per episode1,2,a-c

aA single dose should be sufficient for minor and moderate bleeds. Additional doses of 40 IU/kg can be given.3

Selected 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.

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.
