Pharmacological Properties

Pharmacodynamics

Mechanism of Action

RIXUBIS contains recombinant coagulation factor IX (nonacog gamma). Factor IX is a single-chain glycoprotein with a molecular weight of approximately 68,000 daltons. It is a vitamin K-dependent clotting factor produced in the liver. Factor IX is activated by factor XIa in the intrinsic coagulation pathway and by the factor VII/tissue factor complex in the extrinsic coagulation pathway. Activated factor IX, together with activated factor VIII, activates factor X. Activated factor X converts prothrombin into thrombin. Thrombin then converts fibrinogen into fibrin, leading to clot formation.

Pharmacodynamics

Hemophilia B is a sex-linked inherited disorder of the blood coagulation system caused by reduced levels of factor IX, resulting in severe bleeding into joints, muscles, or internal organs, either spontaneously or following trauma or surgery. Replacement therapy increases factor IX plasma levels and thus provides temporary correction of the deficiency, reducing the tendency to bleed.

Clinical Efficacy and Safety

Prevention and control of bleeding in previously treated patients aged 12 years and older

The efficacy of RIXUBIS was evaluated in the uncontrolled part of a combined open-label phase 1/3 study, in which 73 patients aged 12–59 years who had previously been treated received RIXUBIS for prophylaxis and/or on-demand treatment of bleeding episodes. All patients had severe (factor IX level < 1%) or moderate (factor IX level < 2%) hemophilia B. Of these, 59 patients received RIXUBIS for prophylaxis. Data from 56 patients who received RIXUBIS for at least 3 months were included in the efficacy analysis population for prophylaxis. Another 14 patients received RIXUBIS only for on-demand treatment of bleeding episodes. Patients in the on-demand treatment cohort were required to have at least 12 documented bleeding episodes requiring treatment during the 12 months prior to study enrollment. The mean duration of treatment in the on-demand cohort was 3.5 ± 1.00 months (median 3.4; range 1.2 to 5.1 months). The mean annualized bleeding rate (ABR) was 33.9 ± 17.37, with a median of 27.0 and a range of 12.9 to 73.1.

The median ABR during prophylaxis with RIXUBIS was 2.0 for all bleeds, 0.0 for spontaneous bleeds, and 0.0 for joint bleeds. Twenty-four patients (42.9%) experienced no bleeding episodes.

A total of 249 bleeding episodes were treated with RIXUBIS, of which 197 were joint bleeds and 52 were non-joint bleeds (in soft tissues, muscles, body cavities, intracranial cavity, and others). Of the 249 bleeding episodes, 163 were moderate in severity, 71 were minor, and 15 were serious. Treatment was individualized based on the severity, cause, and location of the bleed. The majority (211 episodes; 84.7%) of the 249 bleeding episodes were controlled with 1–2 infusions. Hemostatic efficacy in stopping bleeding was rated as excellent or good in 96% of all treated bleeding episodes.

Prevention and control of bleeding in previously treated patients under 12 years of age

The efficacy of RIXUBIS was evaluated in a combined phase 2/3 study, in which a total of 23 male patients aged 1.8–11.8 years (median age: 7.10 years), previously treated, including 11 patients under 6 years of age, received RIXUBIS for prophylaxis and control of bleeding episodes. All patients had severe (factor IX level < 1%) or moderate (factor IX level < 2%) hemophilia B. All 23 patients received prophylactic treatment with RIXUBIS for at least 3 months and were included in the efficacy analysis.

The median ABR was 2.0, 0.0 for spontaneous bleeds, and 0.0 for joint bleeds.

Nine patients (39.1%) had no bleeding episodes.

A total of 26 bleeding episodes were treated with RIXUBIS, of which 23 were trauma-related, 2 were spontaneous, and 1 was of unknown origin. Nineteen bleeds occurred outside joints (in soft tissues, muscles, body cavities, intracranial cavity, and others), and 7 were joint bleeds, one of which was a target joint bleed. Of the 26 bleeding episodes, 15 were minor, 9 were moderate, and 2 were serious. Treatment was individualized based on the severity, cause, and location of the bleed. The majority (23 episodes; 88.5%) were treated with 1–2 infusions. Hemostatic efficacy in stopping bleeding was rated as excellent or good in 96.2% of all treated bleeding episodes.

Perioperative Management

The safety and efficacy of RIXUBIS in the perioperative setting were evaluated in a multicenter, prospective, open-label, uncontrolled phase 3 study involving males with severe and moderate hemophilia B who had previously been treated. The per-protocol efficacy analysis included 37 surgical procedures, including major and minor surgeries, dental procedures, or other surgical invasive interventions, performed in 27 patients aged 17 to 57 years. Twenty procedures were major, including 13 orthopedic surgeries and 3 dental surgeries. Seventeen procedures, including 10 tooth extractions, were considered minor. Patients undergoing major surgery were required to undergo pharmacokinetic (PK) assessment. All patients received doses based on individual stepwise recovery of factor IX activity levels. The recommended initial dose of RIXUBIS was intended to maintain factor IX activity at 80–100% during major surgeries and at 30–60% during minor procedures. RIXUBIS was administered as a bolus intravenous infusion.

Hemostasis was maintained throughout the entire study period.

Pharmacokinetics

Patients aged 12 years and older who have been previously treated

A randomized, double-blind, crossover pharmacokinetic study comparing RIXUBIS and a comparator product was conducted in males without active bleeding (aged 15 years and older) as part of the central combined phase 1/3 study. Patients received either product as a single intravenous infusion. The mean (± standard deviation) and median dose of RIXUBIS in the per-protocol analysis population (n = 25) was 74.69 ± 2.37 and 74.25 IU/kg, respectively, with a range of 71.27 to 79.38 IU/kg. Pharmacokinetic parameters were calculated based on measurements of factor IX activity in blood samples collected over a period of up to 72 hours after each infusion.

The pharmacokinetic assessment of RIXUBIS was repeated in an open-label, uncontrolled study involving males who participated in the initial PK crossover study and who were receiving prophylactic treatment with RIXUBIS for 26 ± 1 weeks (mean ± standard deviation) with a total exposure to RIXUBIS of at least 30 days. The dose range of RIXUBIS used during the repeat pharmacokinetic study was 64.48 to 79.18 IU/kg (n = 23).

Table 1 presents the pharmacokinetic parameters in all evaluable patients (per-protocol analysis).

c Volume of distribution at steady state.

Incremental recovery of factor IX activity level, measured 30 minutes after infusion, was determined in all patients enrolled in the combined phase 1/3 study on day 1 of treatment, at physician visits on weeks 5, 13, and 26, and at study completion or withdrawal, if it did not coincide with the week 26 visit. The obtained data indicate that the incremental recovery remained stable throughout the observation period (see Table 2).

Pediatric population (previously treated, under 12 years of age)

In the combined Phase 2/3 study, initial pharmacokinetic assessment of RIXUBIS was performed in 23 pediatric male patients who were in a non-bleeding state. To reduce discomfort associated with frequent blood sampling for each individual patient, patients were randomized into two groups with different blood sampling sequences. The mean dose (± standard deviation) and median dose of RIXUBIS in the full analysis dataset (n = 23) were 75.50 ± 3.016 and 75.25 IU/kg, respectively, with a range of 70.0 to 83.6 IU/kg. Pharmacokinetic parameters were determined based on measurements of factor IX activity in blood samples collected over a period of up to 72 hours after infusion.

Table 3 presents the pharmacokinetic parameters for all patients (full analysis dataset).

Incremental recovery of factor IX activity level at 30 minutes after infusion was determined in all patients enrolled in the combined phase 2/3 study at assessment of baseline pharmacokinetic parameters (on Day 1 of treatment), at study visits on Weeks 5, 13, and 26, and at the time of study completion or discontinuation, if it did not coincide with the Week 26 visit. The obtained data indicate that the incremental recovery over time remains stable across all pediatric age groups (see Tables 4, 5, and 6 below).

Clinical characteristics.

Indications.

For the treatment and prevention of bleeding in patients with hemophilia B (congenital factor IX deficiency).

RIXUBIS is indicated for patients of all age groups.

Contraindications.

Hypersensitivity to the active substance or to any of the excipients listed in the section "Composition".

Known allergic reaction to hamster proteins.

Interaction with other medicinal products and other forms of interaction.

No interactions have been reported between medicinal products based on recombinant human coagulation factor IX (rDNA) and other medicinal products.

Special precautions for use.

Traceability

To improve traceability of biological medicinal products, the name and batch number of the administered product should be clearly documented, for example in the patient's diary.

Hypersensitivity

Allergic-type hypersensitivity reactions have been reported with the use of RIXUBIS. The medicinal product contains residual amounts of hamster proteins. In case of symptoms of hypersensitivity, patients or caregivers should be advised to immediately discontinue the use of the medicinal product and contact their physician. Patients should be informed about early signs of hypersensitivity reactions, including urticaria, generalized urticaria, chest tightness, wheezing, hypotension, and anaphylaxis.

The risk is highest during initial treatment with factor IX concentrates in previously untreated patients, especially in patients with a high risk of gene mutations. Publications have reported an association between the development of factor IX inhibitors and allergic reactions, particularly in patients with a high risk of gene mutations. Therefore, patients experiencing allergic reactions should be tested for the presence of such inhibitors.

In case of shock, standard shock treatment should be administered.

Inhibitors

After repeated treatment with recombinant DNA-derived human coagulation factor IX products, patients should be monitored for the development of neutralizing antibodies (inhibitors). The inhibitor levels should be determined in Bethesda Units (BU) using an appropriate biological assay method.

Publications have reported an association between the development of factor IX inhibitors and allergic reactions. Therefore, patients with allergic reactions should be tested for the presence of such inhibitors. Patients who have developed factor IX inhibitors are at increased risk of developing anaphylaxis upon re-exposure to factor IX.

Due to the risk of allergic reactions with factor IX concentrates, initial administration of factor IX should, at the discretion of the treating physician, be performed under medical supervision to ensure appropriate medical care can be provided in case of allergic reactions.

Nephrotic syndrome

Cases of nephrotic syndrome have been reported following immune tolerance induction in patients with hemophilia B who had previously developed factor IX inhibitors.

Thromboembolism

Due to the potential risk of thrombotic complications, clinical monitoring for early signs of thrombosis and consumptive coagulopathy should be implemented through appropriate biological testing when this product is administered to patients with liver disease, postoperative patients, neonates, or patients at risk of thrombotic events or disseminated intravascular coagulation (DIC). In each of these cases, the benefits of treatment with RIXUBIS should be carefully weighed against the risk of such complications.

Cardiovascular disorders

In patients with pre-existing cardiovascular disorders, replacement therapy with factor IX may increase the risk of cardiovascular complications.

Complications associated with catheter use

If a central venous access device (CVAD) is required, possible complications related to CVAD use should be considered, including local infections, bacteremia, and thrombosis at the catheter site.

Considerations regarding excipients

After reconstitution, this medicinal product contains less than 1 mmol (23 mg) of sodium per vial, i.e., essentially "sodium-free". Depending on the patient's body weight and prescribed dosage, patients may receive more than one vial of RIXUBIS, which should be taken into account when following a sodium-controlled diet.

Elderly patients

Patients aged 65 years and older were not included in clinical trials of RIXUBIS. It is unknown whether their response to treatment differs from that of younger patients. As with all other patients, dose selection for elderly patients should be made on an individual basis.

Children

The above warnings and precautions apply to the treatment of both adults and children.

Use during pregnancy or breastfeeding.

Pregnancy

Data on the use of factor IX in pregnant women are lacking or limited. Reproductive toxicity studies of factor IX in animals have not been conducted.

Factor IX should be used during pregnancy and breastfeeding only if clearly indicated.

Breastfeeding

There are no data on the excretion of factor IX or its metabolites in human breast milk.

Fertility

There is no information on the effect of factor IX on fertility.

Ability to affect reaction speed when driving or operating machinery.

RIXUBIS has no influence on the ability to drive or operate machinery.

Method of Administration and Dosage

Treatment should be carried out under the supervision of a physician experienced in the management of hemophilia.

Monitoring During Treatment

Appropriate monitoring of Factor IX levels is recommended during treatment to guide dosing and the frequency of repeat infusions. The response to Factor IX may vary among individual patients, with differing half-life and recovery values. Dose adjustments based on body weight may be necessary for patients with low or excessive body weight. During major surgical procedures, careful monitoring during replacement therapy is essential, achieved through coagulation factor assays (plasma Factor IX activity).

To ensure attainment of desired plasma Factor IX activity levels, careful monitoring using an appropriate Factor IX activity assay is recommended, with corresponding adjustments in dose and frequency of repeat infusions if necessary. When using the one-stage in vitro assay of coagulation factors based on activated partial thromboplastin time (aPTT) to determine Factor IX activity in patient plasma samples, the results may significantly depend on both the type of aPTT reagent and the reference standard used. This is particularly important when changing laboratories and/or reagents used for the assay.

Dosage

The required dose and duration of replacement therapy depend on the severity of Factor IX deficiency, the location and severity of bleeding, as well as the patient's clinical condition, age, and pharmacokinetic parameters of Factor IX, such as the recovery increment and half-life.

The administered amount of Factor IX is expressed in International Units (IU) according to the current WHO standard for Factor IX-containing medicinal products. Factor IX activity in plasma is expressed either as a percentage (relative to the normal human plasma value) or in International Units (according to the International Standard for Factor IX in plasma).

One International Unit (IU) of Factor IX activity corresponds to the activity level of Factor IX in 1 mL of normal human plasma.

Adults

On-demand Treatment

The required dose of Factor IX for patients aged 12 years and older is calculated based on empirical data indicating that administration of 1 International Unit (IU) of Factor IX per kg of body weight increases Factor IX activity in plasma by 0.9 IU/dL (range: 0.5–1.4 IU/dL) or 0.9% of normal activity.

The required dose is determined using the formula below.

For a stepwise increase in activity level restoration of 0.9 IU/dL per 1 IU/kg, the dose is calculated using the following formula:

The dose level and frequency of scheduled administration should always be directed toward ensuring clinical efficacy in each individual patient.

In the event of the hemorrhagic manifestations listed below, factor IX activity levels should not be lower than the specified plasma activity level (% of normal or IU/dL) for the appropriate duration of time. Table 7 can be used to determine dosing for bleeding episodes and surgical interventions.

Table 7

Careful monitoring of replacement therapy is particularly important in the case of major surgery or life-threatening bleeding.

Prophylaxis

For long-term prophylaxis of bleeding in patients aged 12 years and older with severe haemophilia B, doses of 40–60 IU of factor IX per kg body weight administered every 3–4 days are generally used. In some cases, depending on pharmacokinetics, age, bleeding phenotype, and level of physical activity, it may be necessary to shorten the intervals between doses or increase the dose.

Continuous infusion

Do not administer RIXUBIS by continuous infusion.

Method of administration

Intravenous administration.

If the patient or a caregiver is to administer the medication, they must be properly trained in performing this procedure.

RIXUBIS should be administered at a rate comfortable for the patient, up to a maximum of 10 ml/min.

After reconstitution, the solution is clear, colourless, free of foreign particulate matter, with a pH of 6.8–7.2. Osmolality is greater than 240 mOsm/kg.

Only plastic syringes with a Luer-lock tip should be used for administration of this product.

RIXUBIS is administered intravenously after reconstitution of the powder with the solvent supplied.

• Use only the solvent and reconstitution device (BAXJECT II) provided in the package for preparing the solution.
• A syringe with a Luer-lock tip must be used for administration.
• Do not use the BAXJECT II device if it is damaged, if its sterile protective system or packaging is compromised, or if there are any signs of deterioration.

Reconstitution

Use aseptic techniques.

1. If the medicinal product has been stored in the refrigerator, remove the RIXUBIS powder vial and the solvent vial from the refrigerator and allow them to warm to room temperature (15 °C to 30 °C).
2. Wash hands thoroughly with warm water and soap.
3. Remove the caps from the powder and solvent vials.
4. Wipe the stoppers with alcohol swabs. Place the vials on a clean, flat surface.
5. Open the BAXJECT II device package by peeling off the paper film, taking care not to touch the inner surface of the device (Figure a). Do not remove the device from the package.
6. Turn the package upside down and attach the clear plastic spike to the solvent vial stopper. Holding the package by its edges, remove the package from the BAXJECT II device (Figure b). Do not remove the blue cap from the BAXJECT II device.
7. With the BAXJECT II device now attached to the solvent vial, invert the system so that the solvent vial is above the device. Attach the white plastic spike to the stopper of the RIXUBIS vial. By vacuum action, the solvent will transfer into the vial containing RIXUBIS (Figure c).
8. Gently mix until the powder is completely dissolved. The product dissolves rapidly (within 2 minutes). Ensure that RIXUBIS is completely dissolved, otherwise not all of the reconstituted product will pass through the filter of the device. Reconstituted medicinal products should be inspected visually for particulate matter and discoloration prior to administration. The solution should be clear or slightly opalescent. Do not use solutions that are cloudy or contain precipitate.

Do not cool the medicinal product after reconstitution. Use it immediately after preparation.

Administration

Use aseptic techniques.

1. Remove the blue cap from the BAXJECT II transfer device. Take care not to draw air into the syringe. Attach the syringe to the BAXJECT II transfer device (Figure d).
2. Invert the system (the vial with reconstituted solution should be on top). Fill the syringe with reconstituted solution by slowly pulling back the plunger (Figure e).
3. Disconnect the syringe.
4. Attach a butterfly needle to the syringe. Administer the solution intravenously. The solution should be administered slowly at a rate comfortable for the patient, no faster than 10 ml per minute.

Always record the name and batch number of the RIXUBIS product (for example, in your personal diary) whenever using the medicine, in order to keep information about the medicinal products you have used.

Any unused medicinal product or waste material should be disposed of in accordance with local requirements.

The chemical and physical stability of the diluted, ready-to-use medicinal product is 3 hours at temperatures not exceeding 30 °C. From a microbiological point of view, even though the dilution method excludes microbial contamination, the medicinal product should be used immediately. If the medicinal product is not used immediately, the duration and conditions of storage are the responsibility of the user. Do not refrigerate.

Children

Patients aged 12 to 17 years

The dosing is the same for adults and children aged 12 to 17 years.

Patients under 12 years of age

On-demand treatment

The required dose of factor IX for patients under 12 years of age is calculated based on empirical findings indicating that administration of one international unit (IU) of factor IX per 1 kg body weight results in an increase of factor IX activity in blood plasma by 0.7 IU/dL (range from 0.31 to 1.0 IU/dL) or 0.7% of normal activity.

The required dose is determined using the formula below.

For stepwise increase in activity level restoration of 0.7 IU/dl per 1 IU/kg, the dose is calculated using the following formula:

The same table used for adults (see Table 7 above) can be applied to determine dosing during bleeding episodes and surgical interventions.

Prophylaxis

The recommended dose range for treating pediatric patients under 12 years of age is 40 to 80 IU/kg administered every 3–4 days. In some cases, depending on pharmacokinetics, age, bleeding phenotype, and the patient's level of physical activity, it may be necessary to reduce the dosing intervals or increase the dose.

Overdose.

Effects of doses higher than recommended for RIXUBIS have not been described.

Adverse reactions

Rare cases of hypersensitivity or allergic reactions (which may include angioneurotic edema, burning and itching sensations at the infusion site, chills, facial flushing, generalized urticaria, headache, rash, hypotension, lethargy, nausea, restlessness, tachycardia, chest tightness, tinnitus, vomiting, wheezing) have been observed, which occasionally may progress to severe anaphylaxis (including shock), occurring in close temporal association with administration of factor IX inhibitors.

Cases of nephrotic syndrome have been reported in patients with hemophilia B and a history of allergic reactions, following immune tolerance induction therapy in the presence of factor IX inhibitors.

Very rarely, cases of antibody formation against hamster proteins have been observed, associated with the occurrence of hypersensitivity reactions.

In patients with hemophilia B, neutralizing antibodies (inhibitors) to factor IX may develop, manifesting as suboptimal response to treatment. In such cases, consultation with a specialized hemophilia treatment center is recommended.

Administration of factor IX-containing medicinal products carries a potential risk of thromboembolic events, with a higher risk associated with the use of low-purity (low-level purified) factor IX preparations. Use of low-purity factor IX products has been associated with cases of myocardial infarction, disseminated intravascular coagulation (DIC), venous thrombosis, and pulmonary embolism. Such adverse reactions are rarely observed with high-purity factor IX products.

List of adverse reactions in tabular form

A total of 99 individuals received at least one dose of RIXUBIS in clinical studies. Overall, 5 adverse reactions were reported. The table below presents adverse reactions by system organ classes (SOC) according to the MedDRA classification (using preferred terms).

The frequency of adverse reactions is classified as follows: very common (> 1/10), common (> 1/100 to < 1/10), uncommon (> 1/1000 to < 1/100), rare (> 1/10,000 to < 1/1000), very rare (< 1/10,000), frequency not known (cannot be estimated from available data).

Within each frequency category, adverse reactions are listed in order of decreasing severity.

Table 8

a) PR (side effect) is explained below in the section.

Description of individual side effects

Hypersensitivity

Allergic-type reactions were manifested as dyspnea, pruritus, generalized urticaria, and rash.

Children

The frequency, type, and severity of side effects in children are expected to be the same as in adults.
