RIXUBIS 2000 IU POWDER FOR SOLUTION FOR INJECTION - summary of medicine characteristics

RIXUBIS 2000 IU powder and solvent for solution for injection

2 QUALITATIVE AND QUANTITATIVE COMPOSITION

RIXUBIS 2000 IU powder and solvent for solution for injection

One vial contains nominally 2000 IU nonacog gamma, recombinant human coagulation factor IX (rDNA), corresponding to a concentration of 400 IU/ml after reconstitution with 5 ml solvent.

The potency (IU) is determined using the European Pharmacopoeia one stage clotting assay. The specific activity of RIXUBIS is approximately 200–390 IU/mg protein.

Nonacog gamma (recombinant coagulation factor IX) is a single-chain purified glycoprotein that has 415 amino acids. It is produced by recombinant DNA technology in a Chinese hamster ovary (CHO) cell line.

Excipient(s) with known effect:

One vial contains 19 mg sodium.

For the full list of excipients, see section 6.1.

Powder and solvent for solution for injection.

The powder is white to off-white. The solvent is clear and colourless.

4.1 Therapeutic indications

Treatment and prophylaxis of bleeding in patients with haemophilia B (congenital factor IX deficiency).

RIXUBIS is indicated in patients of all age groups.

4.2 Posology and method of administration

Treatment should be under the supervision of a physician experienced in the treatment of haemophilia.

Treatment monitoring

During the course of treatment, appropriate determination of factor IX levels is advised to guide the dose to be administered and the frequency of repeated infusions. Individual patients may vary in their response to factor IX, demonstrating different half-lives and recoveries. Dose based on bodyweight may require adjustment in underweight or overweight patients. In the case of major surgical interventions in particular, precise monitoring of the substitution therapy by means of coagulation analysis (plasma factor IX activity) is indispensable.

To ensure that the desired factor IX activity plasma level has been attained, careful monitoring using an appropriate factor IX activity assay is advised and, if necessary, appropriate adjustments to the dose and the frequency of repeated infusions should be performed. When using an in vitro thromboplastin time (aPTT)-based one stage clotting assay for determining factor IX activity in patients’ blood samples, plasma factor IX activity results can be significantly affected by both the type of aPTT reagent and the reference standard used in the assay. This is of importance particularly when changing the laboratory and/or reagents used in the assay.

Posology

Dose and duration of the substitution therapy depends on the severity of the factor IX deficiency, on the location and extent of the bleeding, and on the patient’s clinical condition, age and pharmacokinetic parameters of factor IX, such as incremental recovery and half-life.

The number of units of factor IX administered is expressed in International Units (IU), which are related to the current WHO standard for factor IX products. Factor IX activity in plasma is expressed either as a percentage (relative to normal human plasma) or in International Units (relative to an International Standard for factor IX in plasma).

One International Unit of factor IX activity is equivalent to that quantity of factor IX in one ml of normal human plasma.

Adult population

On demand treatment:

The calculation of the required dose of factor IX is based on the empirical finding that 1 International Unit factor IX per kg body weight raises the plasma factor IX activity by 0.9 IU/dL (range from 0.5 to 1.4 IU/dL) or 0.9% of normal activity in patients 12 years and older (further information see section 5.2).

The required dose is determined using the following formula:

Required = body weight x desired factor IX x reciprocal of observed units          (kg)                  r­ise                     ­recovery (dL/kg)

(%) or (IU/dL)

For an incremental recovery of 0.9 IU/dL per IU/kg, the dose is calculated as follows:

Required = body weight x desired factor IX x 1.1 dL/kg units           (kg) rise

(%) or (IU/dL)

The amount to be administered and the frequency of administration should always be oriented to the clinical effectiveness in the individual case.

In the case of the following haemorrhagic events, the factor IX activity should not fall below the given plasma activity level (in % of normal or IU/dL) in the corresponding period. The following table can be used to guide dosing in bleeding episodes and surgery:

Careful monitoring of replacement therapy is especially important in cases of major surgery or life-threatening haemorrhages.

Prophylaxis

For long-term prophylaxis against bleeding in patients with severe haemophilia B, the usual doses are 40 to 60 IU of factor IX per kilogram of body weight at intervals of 3 to 4 days for patients 12 years and older. In some cases, depending upon the individual patient's phar­macokinetics, age, bleeding phenotype and physical activity, shorter dosage intervals or higher doses may be necessary.

Continuous infusion

Do not administer RIXUBIS by continuous infusion.

Paediatric population

Patients aged 12 to 17 years of age:

Posology is the same in adults and paediatric population from 12 to 17.

Patients less than 12 years of age:

On demand treatment

The calculation of the required dose of factor IX is based on the empirical finding that 1 International Unit factor IX per kg body weight raises the plasma factor IX activity by 0.7 IU/dL (range from 0.31 to 1.0 IU/dL) or 0.7% of normal activity in patients less than 12 years of age (further information see section 5.2).

The required dosage is determined using the following formula:

Patients less than 12 years

Required = body weight x desired factor IX x reciprocal of observed units          (kg)                  r­ise                      r­ecovery (dL/kg)

(%) or (IU/dL)

For an incremental recovery of 0.7 IU/dL per IU/kg, the dose is calculated as follows:

Required = body weight x desired factor IX x 1.4 dL/kg units           (kg) rise

(%) or (IU/dL)

The same table as for adults can be used to guide dosing in bleeding episodes and surgery (see above).

Prophylaxis

The recommended dose range for paediatric patients less than 12 years

is 40 to 80 IU/kg at intervals of 3 to 4 days. In some cases, depending upon the individual patient's phar­macokinetics, age, bleeding phenotype and physical activity, shorter dosage intervals or higher doses may be necessary.

Method of administration

Intravenous use.

In case of self-administration or administration by a caregiver appropriate training is needed.

RIXUBIS should be administered using a rate that ensures the comfort of the patient, up to a maximum of 10 ml/min.

After reconstitution, the solution is clear, colourless, free from foreign particles and has a pH of 6.8 to 7.2. The osmolality is greater than 240 m osmol/kg.

For instructions on reconstitution of the medicinal product before administration, see section 6.6.

Only plastic luer-lock syringes should be used with this product.

4.3 Contraindications

Hypersensitivity to the active substance or to any of the excipients listed in section 6.1.

Known allergic reaction to hamster protein.

4.4 Special warnings and precautions for use

Traceability

In order to improve the traceability of biological medicinal products, the name and the batch number of the administered product should be clearly recorded.

Hypersensitivity

Allergic type hypersensitivity reactions have been reported with RIXUBIS. The product contains traces of hamster proteins. If symptoms of hypersensitivity occur, patients or their caregivers should be advised to discontinue use of the medicinal product immediately and contact their physician. Patients should be informed of the early signs of hypersensitivity reactions including hives, generalised urticaria, tightness of the chest, wheezing, hypotension, and anaphylaxis.

The risk is highest during the early phases of initial exposure to factor IX concentrates in previously untreated patients (PUPs), in particular in patients with high-risk gene mutations. There have been reports in the literature showing an association between the occurrence of a factor IX inhibitor and allergic reactions, in particular in patients with a high-risk gene mutation. Therefore, patients experiencing allergic reactions should be evaluated for the presence of an inhibitor.

In case of shock, standard medical treatment for shock should be implemented.

Inhibitors

After repeated treatment with human coagulation factor IX (rDNA) products, patients should be monitored for the development of neutralising antibodies (inhibitors) that should be quantified in Bethesda Units (BU) using appropriate biological testing.

There have been reports in the literature showing a correlation between the occurrence of a factor IX inhibitor and allergic reactions. Therefore, patients experiencing allergic reactions should be evaluated for the presence of an inhibitor. It should be noted that patients with factor IX inhibitors may be at an increased risk of anaphylaxis with subsequent challenge with factor IX.

Because of the risk of allergic reactions with factor IX concentrates, the initial administrations of factor IX should, according to the treating physician’s jud­gement, be performed under medical observation where proper medical care for allergic reactions could be provided.

Nephrotic syndrome

Nephrotic syndrome has been reported following attempted immune tolerance induction in haemophilia B patients with factor IX inhibitors.

Thromboembolism

Because of the potential risk of thrombotic complications, clinical surveillance for early signs of thrombotic and consumptive coagulopathy should be initiated with appropriate biological testing when administering this product to patients with liver disease, to patients post-operatively, to new-born infants, or to patients at risk of thrombotic phenomena or DIC. In each of these situations, the benefit of treatment with RIXUBIS should be weighed against the risk of these complications.

Cardiovascular events

In patients with existing cardiovascular risk factors, substitution therapy with FIX may increase the cardiovascular ris­k.

Catheter-related complications

If a central venous access device (CVAD) is required, risk of CVAD-related complications including local infections, bacteraemia and catheter site thrombosis should be considered.

Excipient related considerations

This medicine contains less than 1 mmol sodium (23 mg) per vial, that is to say essentially ‘sodium-free’. Depending on body weight and Posology of RIXUBIS, patients could receive more than one vial. This should be taken into consideration if the patient is on a controlled sodium diet.

Elderly

Clinical studies of RIXUBIS did not include subjects aged 65 and over. It is not known whether they respond differently from younger subjects. As for all patients, dose selection for an elderly patient should be individualised.

Paediatric population

The listed warnings and precautions apply both to adults and children.

4.5 Interaction with other medicinal products and other forms of interaction

No interactions of human coagulation factor IX (rDNA) products with other medicinal products have been reported.

4.6 Fertility, pregnancy and lactation

Pregnancy

There are no or limited amount of data from the use of Factor IX in pregnant women. Animal reproduction studies have not been conducted with factor IX. Factor IX should be used during pregnancy and breast-feeding only if clearly indicated.

Breast-feeding

It is unknown whether Factor IX/metabolites are excreted in human milk.

Fertility

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

4.7 Effects on ability to drive and use machines

RIXUBIS has no influence on the ability to drive and use machines.

4.8 Undesirable effects

Summary of the safety profile

Hypersensitivity or allergic reactions (which may include angioedema, burning and stinging at the infusion site, chills, flushing, generalised urticaria, headache, hives, hypotension, lethargy, nausea, restlessness, tachycardia, tightness of the chest, tingling, vomiting, wheezing) have been observed rarely and may in some cases progress to severe anaphylaxis (including shock). In some cases, these reactions have progressed to severe anaphylaxis, and they have occurred in close temporal association with development of factor IX inhibitors (see also 4.4).

Nephrotic syndrome has been reported following attempted immune tolerance induction in haemophilia B patients with factor IX inhibitors and a history of allergic reactions.

Very rarely development of antibodies to hamster protein with related hypersensitivity reactions has been observed.

Patients with haemophilia B may develop neutralising antibodies (inhibitors) to factor IX. If such inhibitors occur, the condition will manifest itself as an insufficient clinical response. In such cases, it is recommended that a specialised haemophilia centre be contacted.

There is a potential risk of thromboembolic episodes following the administration of factor IX products, with a higher risk for low purity preparations. The use of low purity factor IX products has been associated with instances of myocardial infarction, disseminated intravascular coagulation, venous thrombosis and pulmonary embolism. The use of high purity factor IX is rarely associated with such adverse reactions.

Tabulated list of adverse reactions

Clinical studies with RIXUBIS included 99 subjects with at least one exposure to RIXUBIS reporting in total 5 adverse reactions. The table presented below is according to the MedDRA system organ classification (SOC and Preferred Term Level).

Frequencies have been evaluated according to the following convention: very common (>1/10), common (>1/100 to <1/10), uncommon (>1/1,000 to <1/100), rare (>1/10,000 to <1/1,000), very rare (<1/10,000), not known (cannot be estimated from the available data).

Within each frequency grouping, adverse reactions are presented in order of decreasing seriousness.

a) ADR explained in the section below.

Description of selected adverse reactions

Hypersensitivity

Allergic type reactions have been manifested by dyspnoea, pruritus, generalised urticaria and rash.

Paediatric population

Frequency, type and severity of adverse reactions in children are expected to be the same as in adults. However, no data are available on previously untreated patients as only previously treated patients have been enrolled in the clinical studies; no immunogenicity investigation on inhibitor development was therefore made in this at risk population.

Reporting of suspected adverse reactions

Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions via the Yellow Card Scheme at:

www.mhra.gov.uk/y­ellowcard www.mhra.gov.uk/yellowcard or search for MHRA Yellow Card in the Google Play or Apple App Store.

4.9 Overdose

The effects of higher than recommended doses of RIXUBIS have not been characterised.

5.1 Pharmacodynamic properties

Pharmacotherapeutic group: antihaemorrhagics, blood coagulation factor IX. ATC code: B02BD04.

Mechanism of action

RIXUBIS contains recombinant coagulation factor IX (nonacog gamma). Factor IX is a single chain glycoprotein with a molecular mass of about 68,000 Dalton. It is a vitamin K-dependent coagulation factor and it is synthesised in the liver. Factor IX is activated by factor XIa in the intrinsic coagulation pathway and by factor VII/tissue factor complex in the extrinsic pathway. Activated factor IX, in combination with activated factor VIII, activates factor X. Activated factor X converts prothrombin into thrombin. Thrombin then converts fibrinogen into fibrin and a clot is formed.

Pharmacodynamic effects

Haemophilia B is a sex-linked hereditary disorder of blood coagulation due to decreased levels of factor IX and results in profuse bleeding into joints, muscles or internal organs, either spontaneously or as a result of accidental or surgical trauma. By replacement therapy the plasma levels of factor IX is increased, thereby enabling a temporary correction of the factor deficiency and correction of the bleeding tendencies.

Clinical efficacy and safety

Prophylaxis and control of bleeding in previously treated patients 12 years and older

The efficacy of RIXUBIS has been evaluated in the open-label, uncontrolled part of a combined phase 1/3 study, in which a total of 73 male, previously treated patients (PTPs) between 12 and 59 years of age received RIXUBIS either for prophylaxis and/or for the treatment of bleeding episodes on an on-demand basis. All subjects had severe (factor IX level <1%) or moderately severe (factor IX level <2%) haemophilia B. Fifty-nine PTPs received RIXUBIS for prophylaxis. Fifty-six of these PTPs who received RIXUBIS for a minimum of 3 months were included in the efficacy evaluation for prophylaxis. An additional 14 PTPs received RIXUBIS for the treatment of bleeding episodes only. Subjects in the on-demand cohort had to have at least 12 documented bleeding episodes requiring treatment within 12 months prior to enrollment. The mean treatment duration in the on-demand cohort was 3.5±1.00 months (median 3.4, ranging from 1.2 to 5.1 months), the mean total annualised bleeding rate (ABR) was 33.9±17.37 with a median of 27.0, ranging from 12.9 to 73.1.

The median ABR on prophylaxis with RIXUBIS for all bleeds was 2.0, for spontaneous bleeds 0.0, and for joint bleeds 0.0. 24 subjects (42.9%) experienced zero bleeds.

A total of 249 bleeding episodes were treated with RIXUBIS, of which 197 were joint bleeds and 52 non-joint bleeds (soft tissue, muscle, body cavity, intracranial and other). Of a total of 249 bleeding episodes, 163 were moderate, 71 were minor, and 15 were major. Treatment was individualised based on the severity, cause and site of bleed. Of the 249 bleeding episodes, the majority (211; 84.7%) were treated with 1–2 infusions. Haemostatic efficacy at resolution of bleed was rated excellent or good in 96% of all treated bleeding episodes.

Prophylaxis and control of bleeding in PTPs below 12 years:

The efficacy of RIXUBIS has been evaluated in a combined phase 2/3 study, in which a total of 23 male PTPs between 1.8 and 11.8 years (median age 7.10 years) with 11 patients < 6 years, received RIXUBIS for prophylaxis and control of bleeding episodes. All subjects had severe (factor IX level <1%) or moderately severe (factor IX level <2%) haemophilia B.

All 23 subjects received prophylactic treatment with RIXUBIS for a minimum of 3 months and were included in the efficacy evaluation for prophylaxis.

The median ABR was 2.0, for spontaneous bleeds 0.0 and for joint bleeds 0.0. Nine subjects (39.1%) experienced zero bleeds.

A total of 26 bleeding episodes were treated with RIXUBIS, of which 23 bleeds were due to injury, 2 spontaneous and 1 of unknown origin. 19 bleeds were non-joint (soft tissue, muscle, body cavity, intracranial and other) and 7 were joint bleeds of which 1 was a bleed into a target joint. Of the 26 bleeding episodes, 15 were minor, 9 moderate, and 2 major. Treatment was individualised based on the severity, cause and site of bleed The majority (23; 88,5%) were treated with 1–2 infusions. Haemostatic efficacy at resolution of a bleed was rated excellent or good in 96.2% of all treated bleeding episodes.

Perioperative management:

The safety and efficacy in the perioperative setting was evaluated in a phase 3 prospective, open-label, uncontrolled, multicenter study in male PTPs with severe and moderately severe haemophilia B using RIXUBIS. The per-protocol efficacy analysis includes 37 surgeries performed in 27 patients between 17 and 57 years of age undergoing major or minor surgical, dental or other surgical invasive procedures. Twenty procedures were major including 13 orthopaedic and 3 dental surgeries. 17 procedures, including 10 dental extractions, were considered minor. Patients undergoing major surgeries had to perform a pharmacokinetic (PK) evaluation. All patients were dosed based on their most recent individual incremental recovery. The recommended initial loading dose of RIXUBIS was to ensure that during surgery, factor IX activity levels of 80–100% for major surgeries and 30–60% for minor surgeries were maintained. RIXUBIS was administered by bolus infusions.

Haemostasis was maintained throughout the study duration.

Paediatric population

The European Medicines Agency has waived the obligation to submit the results of studies with RIXUBIS in previously untreated patients in the treatment and prophylaxis of bleeding in haemophilia B (see section 4.2 for information on paediatric use).

5.2 Pharmacokinetic properties

Previously treated patients 12 years and older:

A randomised, blinded, controlled, crossover pharmacokinetic study of RIXUBIS and a comparator was conducted in non-bleeding male subjects (>15 years of age) as part of the combined phase 1/3 pivotal study. The subjects received either of the products as a single intravenous infusion. The mean (± SD) and median dose of RIXUBIS in the per protocol analysis set (n=25) were 74.69±2.37 and 74.25 IU/kg, respectively, with a range of 71.27 to 79.38 IU/kg. The pharmacokinetic parameters were calculated from factor IX activitiy measurements in blood samples obtained up to 72 hours following each infusion.

The pharmacokinetic evaluation was repeated for RIXUBIS in an open-label, uncontrolled study with RIXUBIS in male subjects who participated in the initial PK crossover study and had received prophylaxis with RIXUBIS for 26±1 weeks (mean ± SD) and accumulated at least 30 exposure days (EDs) to RIXUBIS. The RIXUBIS dose range in the repeat pharmacokinetics study was 64.48 to 79.18 IU/kg (n=23).

Pharmacokinetic parameters for evaluable subjects (per-protocol analysis) are presented in the table below.

Volume of distribution at steady state

Incremental recovery 30 minutes after infusion was determined for all subjects in the combined phase 1/3 study at exposure day 1, at their week 5, 13, and 26 visits, and at the time of study completion or termination, if it did not coincide with the week 26 visit. The data demonstrate that the incremental recovery is consistent over time (see table below).

Calculated as (C30min-baseline factor IX) divided by the dose in IU/kg, where C30min is the factor IX measurement 30 minutes after infusion.

If not coinciding with week 26 visit.

Paediatric population (previously treated patients younger than 12 years)

All 23 male subjects underwent an initial pharmacokinetic evaluation of RIXUBIS in a non-bleeding state as part of the combined phase 2/3 paediatric study. Subjects were randomised to one of two blood sampling sequences to reduce the burden of frequent blood draws on the individual subjects. The mean (± SD) and median dose of RIXUBIS in the full analysis set (n=23) was 75.50 ± 3.016 and 75.25 IU/kg, respectively, with a range

of 70.0 to 83.6 IU/kg. The pharmacokinetic parameters were calculated from factor IX activity measurements in blood samples obtained up to 72 hours following the infusion.

Pharmacokinetic parameters for all subjects (full analysis set) are presented in the table below.

b

Area under the plasma concentration-time curve from time 0 to infinity. Volume of distribution at steady state

Incremental recovery 30 minutes after infusion was determined for all subjects in the combined phase 2/3 study at the initial pharmacokinetic evaluation (exposure day 1), at week 5, 13, and 26 visits, and at the time of study completion or termination, if it did not coincide with the week 26 visit. The data demonstrate that the incremental recovery is consistent over time across all paediatric age groups. See tables below.

Incremental recovery for RIXUBIS 30 minutes after infusion, both paediatric age groups:

C30min is the factor IX measurement 30 minutes after infusion.

Incremental recovery for RIXUBIS 30 minutes after infusion, paediatric patients < 6 years:

C30min is the factor IX measurement 30 minutes after infusion.

Incremental recovery for RIXUBIS 30 minutes after infusion, paediatric patients 6 to < 12 years:

C30min is the factor IX measurement 30 minutes after infusion.

5.3 Preclinical safety data

RIXUBIS was not thrombogenic at a dose of 750 IU/kg in a rabbit stasis model (Wessler-Test).

RIXUBIS did not cause any adverse clinical, respiratory, or cardiovascular effects up to 450 IU/kg in cynomolgus monkeys.

No investigations on carcinogenicity, fertility impairment, and fetal development have been conducted.

RIXUBIS was well tolerated in single dose and repeated dose toxicity studies conducted in mice, rats and cynomolgus monkeys up to doses of 7500 IU/kg (single dose) and 750 IU/kg (repeated application).
