Where does this data come from?
NADAC (National Average Drug Acquisition Cost) is the CMS weekly pharmacy-acquisition-cost survey — what pharmacies pay. ASP (Average Sales Price) is the CMS Medicare Part B drug-payment file, published quarterly. Medicaid pays is computed by us from CMS State Drug Utilization Data (total reimbursed ÷ units, trailing 12 months) — gross of rebates and inclusive of dispensing fees, so it reflects what Medicaid paid, not an acquisition cost. Medicare drug plans pay is the median negotiated point-of-sale unit cost across plans listing this NDC in the CMS quarterly Prescription Drug Plan pricing files, before rebates. The VA pays is the federal contract price (FSS, and the statutory Big 4 ceiling where listed) from the VA National Acquisition Center pharmaceutical price file. All are free public government data; each measures a different payer, so the figures are not directly comparable.

🧬Biologic — competition comes from biosimilars

Biologics have no small-molecule generics; biosimilar competition is tracked in the FDA Purple Book.

🛡️ Latest patent/protection date listed: FDA patent/protection data lists protections through May 2029. This may affect when biosimilars become widely available, but it is not a guaranteed launch date.
📅 FDA approved May 31, 2017 ⏳ ~2.7 yr to latest listed protection

Why the date isn’t exact: Biosimilar timing can change because patents may be challenged, settled, licensed, added or removed, and litigation can move the real date earlier or later.

Biologic patent Exclusivity
🏛️Reference-product exclusivity
A flat 12 years of FDA market protection from first licensure. No biosimilar can be licensed before it ends — regardless of patents.
🧪Listed biologic patents
Patents the reference maker lists covering the molecule, formulation, or manufacturing. A biosimilar generally can’t launch until these resolve.
🔁Interchangeability
An interchangeable biosimilar may be substituted at the pharmacy (state laws vary). The first one can earn its own exclusivity period.
🛈 What do these terms mean?
Biologic patent
A patent the reference product’s maker has publicly listed. A biosimilar generally can’t launch until these expire — unless they’re invalidated or resolved in a settlement.
Reference-product exclusivity
A flat 12 years of FDA market protection from the biologic’s first licensure (the BPCIA). No biosimilar can be licensed before it ends, regardless of patents.
Interchangeable exclusivity
The first interchangeable biosimilar can earn a period as the only interchangeable version (pharmacists can substitute it without the prescriber).
Earliest biosimilar (LOE)
The latest of all the dates above — the soonest a biosimilar can realistically reach the market. Litigation and settlements can move it earlier.

Biologics have no small-molecule “generics” — competition comes from FDA-licensed biosimilars, tracked in the FDA Purple Book.

Common questions
Is there a biosimilar for REBINYN 500 UNIT VIAL?
No FDA-licensed biosimilar is currently listed for this biologic in the FDA Purple Book.
Why do different websites show different biosimilar dates?
Biosimilar availability isn’t based on one single date. Some sources use the reference-product exclusivity, some use the last listed patent, and patent litigation, settlements, and licenses can all change the real-world launch date. This page shows the underlying Purple Book dates so you can see why estimates differ.
Can a biosimilar launch before the last patent expires?
Sometimes. A biosimilar maker may settle with the reference manufacturer or receive a license to launch earlier. In other cases, the last listed protection delays competition.
What does “current Purple Book estimate” mean?
It means we’re using the latest patent and exclusivity dates currently listed in the FDA Purple Book. It is not a guaranteed launch date.
What does “FDA listed” mean?
It means the product appears in the FDA’s official directory. That’s a good sign a product exists for the U.S. market, but on its own it does not confirm a pharmacy can get it today. Where we have recent retail pricing data, we label it “Availability likely” instead.
What does a patent or protection date mean here?
It’s the latest date currently listed in the FDA Purple Book for a patent or exclusivity on the reference biologic. It can affect when a biosimilar becomes widely available — but it is not a guaranteed launch date. Settlements and licenses can move the real date earlier or later.
Built from the FDA Purple Book Patent List (patents the reference-product sponsor has publicly listed under the BPCIA) plus reference-product exclusivity. Biosimilars cannot launch until these clear; patent litigation and settlements can shift the real date. Biologics have no small-molecule generics — competition comes from FDA-licensed biosimilars, not the Orange Book.
Where does this data come from?
Patents and exclusivity from the FDA Purple Book (biologics), refreshed from public FDA data. Biosimilar launch timing is an estimate, not a guarantee.

Inactive Ingredients / Excipients

Inactive ingredients, also called excipients, are components of the drug product other than the active ingredient. They may include fillers, dyes, coatings, preservatives, flavors, or other formulation ingredients.

A current SPL was checked, but it does not contain a structured or narrative inactive-ingredient list for this product. This does not mean the product has no inactive ingredients.
Where does this data come from?
Source: official FDA Structured Product Labeling (SPL) via DailyMed and the openFDA label index. Structured IACT rows and label-wide narrative are kept separate; availability and product-level specificity depend on the submitted label.

Inactive ingredient FAQ

Are inactive ingredients the same for every manufacturer?
No. Inactive ingredients can differ by manufacturer, dosage form, strength, and package / product version.
Why might an inactive ingredient be missing?
Some SPLs do not provide a complete structured inactive-ingredient list, and older or unusual labels may only include the information in narrative text.
Can inactive ingredients matter?
Yes. They can matter for allergies, intolerances, dyes, gluten / lactose concerns, preservatives, and formulation differences — but confirm with a pharmacist or the manufacturer when it’s clinically important.

2 DOSAGE AND ADMINISTRATION For intravenous infusion after reconstitution only. For intravenous infusion after reconstitution only ( 2 ). • Each carton and vial label for REBINYN states the actual Factor IX potency in international units (IU) ( 2.1 ). On-demand treatment and control of bleeding episodes: • 40 IU/kg body weight for minor and moderate bleeds, and 80 IU/kg body weight for major bleeds.

Additional doses of 40 IU/kg can be given ( 2.1 ). Perioperative management: • Pre-operative dose of 40 IU/kg body weight for minor surgery, and 80 IU/kg body weight for major surgery. As clinically needed for the perioperative management of bleeding, repeated doses of 40 IU/kg (in 1-3 day intervals) within the first week after major surgery may be administered. • Frequency may be extended to once weekly after the first week until bleeding stops and healing is achieved ( 2.1 ).

Routine prophylaxis : • 40 IU/kg body weight once weekly ( 2.1 ).

2.1Dosing Guidelines • Dose and duration of treatment depend on the location and extent of bleeding, and the patient’s clinical condition. • If monitoring of Factor IX activity is performed, use a chromogenic assay or selected one-stage clotting assay validated for use with REBINYN [ see Warnings and Precautions ( 5.5 ) ]. • Each carton and vial label for REBINYN states the actual Factor IX potency in IU. On-demand Treatment and Control of Bleeding Episodes REBINYN dosing for on-demand treatment and control of bleeding episodes is provided in Table 1.

Table 1: Dosing for On-demand Treatment and Control of Bleeding Episodes Type of bleeding Recommended dose IU/kg body weight Additional information Minor and moderate For example: Uncomplicated joint bleeds, minor muscular bleeds, mucosal or subcutaneous bleeds 40 A single dose should be sufficient for minor and moderate bleeds. Additional doses of 40 IU/kg can be given. Major For example: Intracranial, retroperitoneal, iliopsoas and neck bleeds, muscle bleeds with compartment syndrome and bleeds associated with a significant decrease in the hemoglobin level 80 Additional doses of 40 IU/kg can be given.

⛔ Contraindications 53 words ▾

4 CONTRAINDICATIONS REBINYN is contraindicated in patients who have known hypersensitivity to REBINYN or its components (including hamster proteins) [ see Warnings and Precautions ( 5.1 ) and Description ( 11 ) ] Do not use in patients who have known hypersensitivity to REBINYN or its components, including hamster proteins ( 4 ).

⚠️ Warnings and Cautions ~3 min read ▾

5 WARNINGS AND PRECAUTIONS • Hypersensitivity reactions, including anaphylaxis, have occurred. Should hypersensitivity reactions occur, discontinue REBINYN and administer appropriate treatment ( 5.1 ). • Neutralizing antibodies (inhibitors) to Factor IX have occurred following administration of REBINYN. Perform an assay that measures Factor IX inhibitor concentration if bleeding is not controlled with the recommended dose of REBINYN or if plasma Factor IX activity level fails to increase as expected (5.2 , 5.5 ). • The use of Factor IX- products has been associated with the development of thromboembolic complications ( 5.3 ). • Nephrotic syndrome has been reported following immune tolerance induction with Factor IX-containing products in hemophilia B patients with Factor IX inhibitors and a history of allergic reactions to Factor IX.

( 5.4 ) • Factor IX activity assay results may vary with the type of activated partial thromboplastin time reagent used ( 5.5 ).

5.1Hypersensitivity Reactions Allergic-type hypersensitivity reactions, including anaphylaxis, have occurred with REBINYN. The product may contain traces of hamster proteins which in some patients may cause allergic reactions. Signs of allergic reactions, which can progress to anaphylaxis, may include angioedema, chest tightness, difficulty breathing, wheezing, urticaria, and itching.

Observe patients for signs and symptoms of acute hypersensitivity reactions, particularly during the early phases of exposure to the product. Discontinue use of REBINYN if allergic- or anaphylactic - type reactions occur, and initiate appropriate treatment.

5.2Inhibitors 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 [ see Warnings and Precautions (5.5) ].

An association between the development of Factor IX inhibitors and allergic reactions has been reported. Evaluate patients experiencing allergic reactions for the presence of an inhibitor. Patients with Factor IX inhibitors may be at an increased risk of severe allergic reactions with subsequent exposure to Factor IX.

5.3Thrombotic Events The use of Factor IX-containing products has been associated with thromboembolic complications. Due to the potential risk of thromboembolic complications, monitor patients for early signs of thrombotic and consumptive coagulopathy when administering this product to patients with liver disease, post-operatively, to newborn infants, or to patients at risk of thrombosis or disseminated intravascular coagulation (DIC). In each of these situations, the benefit of treatment with REBINYN should be weighed against the risk of these complications.

5.4Nephrotic 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.

5.5Monitoring Laboratory Tests If monitoring of Factor IX activity is performed, use a chromogenic assay or selected one-stage clotting assay validated for use with REBINYN [ see Dosage and Administration ( 2 ) ]. The one-stage clotting assay results can be significantly affected by the type of activated partial thromboplastin time (aPTT) reagent used, which can result in over- or under-estimation of Factor IX activity. Avoid the use of silica-based reagents, as some may overestimate the activity of REBINYN.

If a validated one-stage clotting or chromogenic assay is not available locally, then use of a reference laboratory is recommended. If bleeding is not controlled with the recommen… [Excerpted — this section continues on DailyMed.]

🤒 Adverse Reactions ~3 min read ▾

6 ADVERSE REACTIONS Common adverse reactions (incidence ≥ 1%) in PTPs reported in clinical trials for REBINYN were itching and injection site reactions. Common adverse reactions (incidence ≥ 1%) in PUPs reported in clinical trials for REBINYN were rash, FIX inhibitors, hypersensitivity, itching, injection site reaction, and anaphylactic reaction. The most frequently reported adverse reactions (≥ 1%) in previously treated patients (PTPs) and previously untreated patients (PUPs) were itching and injection site reactions ( 6 ).

Additional frequently reported adverse reactions (≥ 1%) in PUPs included rash, Factor IX inhibition, hypersensitivity, and anaphylactic reaction ( 6 ). In animals administered repeat doses of REBINYN, accumulation of polyethylene-glycol (PEG) was observed in the choroid plexus, pituitary, circumventricular organs, and cranial motor neurons ( 8.4 and 13.2 ). The potential clinical implications of these animal findings are unknown ( 6.3 ).

To report SUSPECTED ADVERSE REACTIONS, contact Novo Nordisk Inc. at 1-877-668-6777 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch.

6.1Clinical 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 reflect the rates observed in clinical practice. Previously Treated Patients (PTPs) In five multicenter, prospective, non-controlled, open-label clinical trials, 115 PTPs [0 to 6 years old: 12 subjects (10%); 7 to 12 years old: 13 subjects (11%); 13 to 17 years old: 18 subjects (16%); ≥18 years old: 72 subjects (63%)] received at least one dose of REBINYN as part of routine prophylaxis, on-demand treatment of bleeding episodes, perioperative management of major and minor surgery, or pharmacokinetic evaluation [ see Clinical Studies (14) ].

A PTP was defined as a subject with a history of at least 150 exposure days to other Factor IX products (adolescent/adult subjects) or 50 exposure days to other Factor IX products (pediatric subjects), and no history of inhibitors. A total of 15,167 injections were administered over a median of 733 days (range: 29- 2951 days), equivalent to 15,137 exposure days and 292 patient-years. Adverse reactions in PTPs are listed in Table 3.

A PUP was defined as a subject previously untreated or exposed to FIX-containing products less than or equal to 3 exposure days (5 previous exposures to blood components was acceptable). A total of 6,737 injections were administered over a median of 996 days (range: 61- 2,233 days), equivalent to 6,709 exposure days and 142 patient-years. Adverse reactions in PUPs are listed in Table 4.

👥 Use in Specific Populations ~2 min read ▾

8 USE IN SPECIFIC POPULATIONS Pediatric Use: No dose adjustment is needed ( 8.4 ).

8.1Pregnancy Risk Summary There are no data with REBINYN use in pregnant women to determine whether there is a drug-associated risk. Animal reproduction studies have not been conducted with REBINYN. It is unknown whether REBINYN can cause fetal harm when administered to a pregnant woman or can affect fertility.

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.

8.2Lactation Risk Summary There is no information regarding the presence of REBINYN in human milk, the effect on the breastfed infant, and the effects on milk production. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for REBINYN and any potential adverse effects on the breastfed infant from REBINYN or from the underlying maternal condition.

8.4Pediatric Use Safety and efficacy of REBINYN were evaluated in four clinical trials that included 43 PTPs and in one clinical trial that included 50 pediatric PUPs [ see Adverse Reactions ( 6 ) and Clinical Studies ( 14 ) ]. Twelve of these subjects were ≤ 6 years of age; 13 subjects were 7 to 12 years of age; and 18 subjects were 13 to 17 years of age. Pharmacokinetic parameters were evaluated for 28 of the pediatric PTPs who were treated with REBINYN 40 IU/kg [ see Clinical Pharmacology ( 12.3 ) ].

Body weight-adjusted clearance was observed to be higher for pediatric subjects than for adult subjects. However, in clinical trials, no dose adjustment was needed in pediatric subjects who received a fixed dose of 40 IU/kg every week for routine prophylaxis. Juvenile Animal Toxicity Data A juvenile animal neurotoxicity study was conducted to evaluate the potential neurotoxicity of REBINYN when intravenously administered 120-1200 IU/kg/twice weekly in immature male rats from 3 to 13 weeks of age, followed by a 13-week treatment-free period.

Accumulation of PEG was observed in the choroid plexus, pituitary, circumventricular organs, and the cranial motor neurons. PEG levels in these tissues increased with dose and dose duration (10 weeks) and remained detectable after the 13-week treatment-free period. Treatment-related PEG-positive vacuolated macrophages were observed in the pituitary.

The accumulation of PEG was not associated with neurobehavioral changes, fertility, or functional effects.

8.5Geriatric Use Clinical studies of REBINYN did not include sufficient numbers of subjects age 65 and over to determine whether or not they respond differently than younger subjects. Animals administered repeat doses of REBINYN showed accumulation of PEG in the choroid plexus, pituitary, circumventricular organs, and cranial motor neurons. [ see Use in Specific Populations ( 8.4 ) and Animal Toxicology and/or Pharmacology ( 13.2 ) ]. The potential clinical implications of these animal findings are unknown.

No adverse neurologic effects of PEG have been reported in adults exposed to REBINYN during clinical trials, however, use in older adults with baseline cognitive dysfunction has not been fully evaluated [ see Neurologic Considerations ( 6.3 ) ].

12 CLINICAL PHARMACOLOGY

12.1Mechanism of Action Patients with hemophilia B are deficient in coagulation Factor IX, which is required for effective hemostasis. Treatment with REBINYN temporarily replaces the missing coagulation Factor IX. The Factor IX in REBINYN is conjugated to a 40-kDa polyethylene glycol molecule, which slows down its removal from the blood circulation.

12.2Pharmacodynamics The administration of REBINYN increases plasma levels of Factor IX and can temporarily correct the coagulation defect in hemophilia B patients, as reflected by a decrease in aPTT.

12.3Pharmacokinetics Pharmacokinetic (PK) parameters of REBINYN were evaluated in previously treated subjects, including a subset of subjects in the adult/adolescent trial and all subjects in the main phase of the pediatric trial [ see Clinical Studies (14) ]. PK samples were collected prior to dosing and at multiple time points up to 168 hours after dosing. The analysis of plasma samples was conducted using the one-stage clotting assay.

Steady state pharmacokinetic parameters for adolescents and adults following once-weekly prophylactic treatment of REBINYN 40 IU/kg are shown in Table 5.

📋 Description ~2 min read ▾

11 DESCRIPTION REBINYN is a sterile, non-pyrogenic, white to off-white lyophilized powder for reconstitution with the provided histidine diluent for intravenous infusion. After reconstitution, the solution appears as a clear and colorless to slightly yellow liquid, free from visible particles and contains the following excipients per mL: sodium chloride, 2.34 mg; histidine, 3.10 mg; sucrose, 10 mg; mannitol, 25 mg; polysorbate 80, 0.05 mg. REBINYN is available in single-dose vials containing the labeled amount of Factor IX activity, expressed in IU.

Each vial contains nominally 500 IU, 1000 IU, 2000, or 3000 IU. REBINYN potency is assigned using an in vitro , activated partial thromboplastin time (aPTT)-based, one-stage clotting assay calibrated against the World Health Organization (WHO) international standard for Factor IX concentrates. REBINYN contains no preservatives.

REBINYN is a purified recombinant human Factor IX (rFIX) with a 40 kilodalton (kDa) polyethylene-glycol (PEG) conjugated to the protein. The 40 kDa PEG group is selectively attached to specific -N-linked glycans in the rFIX activation peptide, with mono-PEGylated rFIX as the predominant form of REBINYN. The rFIX protein in REBINYN consists of a gamma-carboxylated (Gla) domain, two EGF-like (epidermal growth factor) domains, an activation peptide (which is cleaved off upon activation), and a protease domain.

Once activated, the resulting rFIX has structural and functional properties similar to those of endogenous activated Factor IX. The primary amino acid sequence in REBINYN is identical to the Thr148 allelic form of human plasma-derived Factor IX and consists of 415 amino acids. The average molecular weight of REBINYN is approximately 98 kDa and the molecular weight of the protein moiety alone is 56 kDa.

The nominal specific activity of REBINYN is 144 IU/mg protein. REBINYN is produced by recombinant DNA technology in Chinese Hamster Ovary (CHO) cells. No additives of human or animal origin are used in the cell culture, purification, conjugation, or formulation of REBINYN.

The rFIX protein is purified by a series of chromatographic steps, including an affinity chromatography step using a monoclonal antibody (produced in CHO cells), to selectively isolate rFIX from the cell culture medium. The production process includes two dedicated viral clearance steps, namely a detergent treatment step for inactivation and a 20 nm filtration step for removal of viruses. The conjugation of the PEG-group is done by an enzymatic reaction during the purification process, followed by final purification of REBINYN.

🔬 Clinical Studies ~3 min read ▾

14 CLINICAL STUDIES Safety and efficacy of REBINYN was evaluated in five multicenter, non-controlled, open-label trials in on-demand treatment of bleeding episodes, perioperative management of major and minor surgery, and routine prophylaxis or pharmacokinetic evaluation in PTPs with hemophilia B (Factor IX activity ≤ 2%). The efficacy evaluation included 105 PTPs [62 adults (18 to 65 years old), 18 adolescents (13 to 17 years old), and 25 children (1 to 12 years old)]. • Adult/adolescent trial: The trial included 74 adolescent and adult subjects.

There were two routine prophylaxis arms, with single-blind randomization to either 10 IU/kg or 40 IU/kg once-weekly for approximately 52 weeks, and an open-label on-demand treatment arm for approximately 28 weeks. • Surgery trial: The surgery trial included 13 adolescent and adult subjects who received one infusion of REBINYN 80 IU/kg on the day of surgery, and post-operatively received infusions of 40 IU/kg, at the investigator’s discretion, for up to 3 weeks after surgery. • Pediatric trial: The main phase of the pediatric trial included 25 PTPs (1 to 12 years old) in which subjects received routine prophylaxis with REBINYN 40 IU/kg once weekly for approximately 52 weeks until 50 EDs were reached.

Treatment of Bleeding Episodes Previously Treated Patients A total of 250 bleeding episodes were reported in 45 out of 69 PTPs receiving either REBINYN 40 IU/kg prophylaxis or on-demand treatment in the clinical program. Bleeding episodes were treated with REBINYN at 40 IU/kg for minor or moderate bleeds or 80 IU/kg for major bleeds, with additional doses of 40 IU/kg as needed. The median dose to treat a bleeding episode was 42 IU/kg.

An overall assessment of efficacy was performed by the subject (for home treatment) or the study site investigator (for treatment under medical supervision) using a 4-point scale of excellent, good, moderate, or poor. The overall success rate (defined as excellent or good) for treatment of bleeding episodes was 95% as shown in Table 9. The success rate and dose needed for treatment of bleeding episodes were independent of the location of the bleeding.

The success rate for treatment of bleeding episodes was also independent of whether the bleed was traumatic or spontaneous.

Efficacy was assessed according to a four-point scale using: Excellent: Abrupt pain relief and/or clear improvement in objective signs of bleeding within 8 hours after a single injection; Good: Noticeable pain relief and/or improvement in signs of bleeding within 8 hours after a single injection; Moderate: Probable or slight beneficial effect within the first 8 hours after the first injection but requiring more than one injection within 8 hours; Poor: No improvement, or worsening of symptoms within 8 hours after the second of two injections.

Perioperative Management In the surgery trial, the efficacy analysis of REBINYN in perioperative management included 13 surgical procedures of which 9 were major and performed in 13 previously treated adolescent and adult patients. The procedures included 9 orthopedic, 1 gastrointestinal and 3 in the oral cavity. The hemostatic effect during surgery was evaluated on a four-point scale of excellent, good, moderate, or poor.

The intraoperative hemostatic effect was rated as excellent or good for the 13 surgeries, for a success rate of 100%. A pre-operative dose of 80 IU/kg REBINYN was effec… [Excerpted — this section continues on DailyMed.]

In a juvenile rat study (3 to 13 week old male rats), fertility was unaffected following 9 weeks of twice weekly administrations of up to 1200 IU/kg [ see Use in Specific Populations ( 8.4 ) ].

13.2Animal Toxicology and/or Pharmacology REBINYN was intravenously administered in repeat-dose toxicity studies in adult immune-deficient rats (40-1200 IU/kg/week for 26 weeks), immune-competent monkeys (350-3750 IU/kg/week for 4 weeks), and juvenile immune-competent rats (120‑1200 IU/kg/twice weekly for 10 weeks). Accumulation of PEG was detected in epithelial cells of the choroid plexus in the brain of the adult rats and monkeys. This finding was not associated with morphological changes or abnormal clinical signs.

In juvenile rats, more comprehensive assessment of brain tissues demonstrated PEG accumulation in the choroid plexus, pituitary, circumventricular organs, and the cranial motor neurons [ see Use in Specific Populations ( 8.4 ) ].

This Patient Product Information does not take the place of talking with your healthcare provider about your medical condition or treatment. If you have questions about REBINYN after reading this information, ask your healthcare provider.

What is the most important information I need to know about REBINYN? Do not attempt to do an infusion yourself unless you have been taught how by your healthcare provider or hemophilia treatment center. You must carefully follow your healthcare provider's instructions regarding the dose and schedule for infusing REBINYN so that your treatment will work best for you.

What is REBINYN? REBINYN is an injectable medicine used to replace clotting Factor IX that is missing in patients with hemophilia B. Hemophilia B is an inherited bleeding disorder in all age groups that prevents blood from clotting normally.

REBINYN is used to treat, prevent, or reduce the frequency (number) of bleeding episodes in people with hemophilia B. Your healthcare provider may give you REBINYN when you have surgery. Who should not use REBINYN?

You should not use REBINYN if you • are allergic to Factor IX or any of the other ingredients of REBINYN • if you are allergic to hamster proteins If you are not sure, talk to your healthcare provider before using this medicine. Tell your healthcare provider if you are pregnant or nursing because REBINYN might not be right for you. What should I tell my healthcare provider before I use REBINYN?

You should tell your healthcare provider if you • Have or have had any medical conditions. • Take any medicines, including non-prescription medicines and dietary supplements. • Are nursing. It is not known if REBINYN passes into breast milk or if it can harm your baby. • Are pregnant or planning to become pregnant. It is not known if REBINYN may harm your unborn baby. • Have been told that you have inhibitors to Factor IX (because REBINYN may not work for you).

How should I use REBINYN? Treatment with REBINYN should be started by a healthcare provider who is experienced in the care of patients with hemophilia B. REBINYN is given as an infusion into the vein.

You may infuse REBINYN 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 hemophilia treatment center or healthcare provider. Many people with hemophilia B learn to infuse the medicine by themselves or with the help of a family member.

Your healthcare provider will tell you how much REBINYN to use based on your weight, the severity of your hemophilia B, and where you are bleeding. Your dose will be calculated in international units, IU. Call your healthcare provider right away if your bleeding does not stop after taking REBINYN.

If your bleeding is not adequately controlled, it could be due to the development of Factor IX inhibitors. This should be checked by your healthcare provider. You might need a higher dose of REBINYN or even a different product to control bleeding.

Medicaid utilization & spend

📍 This exact package only: Medicaid data is reported per full 11-digit NDC — labeler, product and pack size — so every number here is for this package alone, not the drug overall. Other pack sizes report separately.
💊 Pharmacy benefit only: These are Medicaid outpatient pharmacy claims, billed by NDC. They exclude the medical benefit — clinic- or hospital-administered drugs billed under HCPCS J-codes — so drugs used mostly that way (e.g. Avastin, Lucentis, Keytruda) can look low or missing here. That’s expected, not an error.

ⓘ The newest quarter is usually incomplete when first published; states restate recent quarters in later CMS releases, so the latest figures typically revise upward. State coverage-policy changes can also shift quarter-to-quarter totals.

Medicaid utilization by pack size

Medicaid (SDUD) totals over the four most recent reported quarters for every package size of this drug — handy when a specific package (e.g. a starter/titration pack) carries little or no Medicaid volume on its own.

About this NDC listing & data coverage

Finished prescription product Kit / multi-component package

Kit / multi-component package

This NDC identifies a kit — a package containing more than one component. Structured data (pricing, ingredients, equivalents) is often reported per component rather than for the kit NDC itself, which can make this page look thinner than the components' own pages.

Questions about this listing

Why is there no price listed?
The pricing shown on our NDC pages comes from CMS NADAC, a voluntary survey of retail community pharmacy invoices. CMS does not publish a NADAC for every NDC — packages outside the retail survey (institutional and hospital products, bulk packages, discontinued items, and many OTC items) may never receive one. A missing price reflects the survey's scope, not this product's actual cost, and does not mean the product is free or unavailable.
Is the NDC printed on the package the same as the 11-digit billing NDC?
Yes, they identify this exact package in different formats. The form printed on the packaging and shown on DailyMed is the one the FDA registered. Insurance claims use a fixed 11-digit 5-4-2 format, so the short segment is padded with a leading zero and the dashes are dropped. The Identity section at the top of this page lists each form of this code.
Is this package still being marketed?
Yes, per the latest FDA NDC Directory data on this page: this package is listed as actively marketed, with no marketing end date reported by Novo Nordisk. Listing status can change — the directory data on this page refreshes weekly.
Does this product come in other package sizes?
Yes — the FDA directory lists 1 other package presentation of this same product, including 1 kit (00169-7905-97). Each has its own NDC and its own page — see the package list near the top of this page.
Who lists this product with the FDA?
Novo Nordisk is the labeler of record for this NDC — the company under whose FDA-assigned code the package is listed. The labeler may be the manufacturer itself or a distributor marketing the product under its own code.
Do I need a prescription for this product?
This NDC is listed with FDA as a prescription product, so it is dispensed under a prescriber's order. Your pharmacist can tell you whether any over-the-counter forms of the same medication exist.
Does this product have a billing J-code?
Yes — this NDC cross-references HCPCS code J7203 for medical-claim billing (typically used when a product is administered in a clinical setting rather than dispensed at a retail pharmacy). See the Billing section on this page.
This page identifies an FDA-listed package (the NDC) and reports public regulatory and pricing data about the listing. It is reference information, not a medical recommendation — talk to your pharmacist or prescriber about your own medication.
Where does this data come from?
Listing facts (marketing category, packager status, marketing dates) from the FDA openFDA NDC Directory; label availability from DailyMed; pricing coverage from CMS NADAC; equivalence scope from the FDA Orange Book.
For educational and professional reference only — not medical advice. Pricing reflects published NADAC and CMS ASP (free public data) and may differ from your acquisition cost; always verify before billing or dispensing.
