2 DOSAGE AND ADMINISTRATION

For intravenous use after reconstitution only.

For intravenous use after reconstitution only.

One international unit of Berinin P per kg body weight increases the circulating activity of factor IX by 0.98 IU/dL (2.1)

Initial dose:

Required factor IX units (IU) = body weight (kg) x desired factor IX increase (% of normal or IU/dL) x reciprocal of observed recovery (IU/kg per IU/dL) (2.1)

Maintenance dose:

Depends upon the type of bleed or surgery, clinical response, and the severity of the underlying factor IX deficiency (2.1)

2.1 Dose


Initial Dose

Calculate the initial dose of Berinin P based on the empirical finding that one international unit (IU) of Berinin P per kg body weight increases the circulating level of factor IX by 0.98 international units/dL (IU/dL) of plasma in adults and children ≥ 12 years of age.

Initial Dose = body weight (kg) x desired factor IX increase (% of normal or IU/dL)
 × reciprocal of observed recovery (IU/kg per IU/dL)

Incremental Recovery in Previously Treated Patients (PTPs)

Base calculation of the dose on the patient’s individual incremental recovery using serial factor IX activity assays, to account for the wide range of inter-individual differences in incremental recovery and the type of aPTT reagent used for the assay. Titrate the dose based on the patient’s clinical response and individual pharmacokinetics, in particular incremental recovery and half-life.

For an incremental recovery of 0.98 IU/dL per IU/kg, calculate the dose as follows:

Dose (IU) = body weight (kg) x desired factor IX increase (% of normal or IU/dL)
 × 1.02 dL/kg

Examples (assuming patient’s baseline factor IX level is < 1% of normal):


Control and Prevention of Bleeding and Perioperative Management

Guides for dosing Berinin P in the control and prevention of bleeding episodes (Table 1) and perioperative management (Table 2) are provided in the tables below. Individual patients may vary in their response to factor IX, and may demonstrate different levels of in vivo recovery and different half-lives.

For surgical procedures, initiate treatment with Berinin P early enough pre-operatively to achieve and maintain the desired factor IX level before starting the procedure.

4 CONTRAINDICATIONS

Berinin P is contraindicated in patients who have known hypersensitivity to Berinin P or its excipients, including hamster protein [see Warnings and Precautions (5.1) ].

Do not use in patients with known hypersensitivity to Berinin P or its excipients, including hamster protein (4)

5 WARNINGS AND PRECAUTIONS

5.1 Hypersensitivity Reactions

Hypersensitivity reactions, including anaphylaxis, may occur with Berinin P, and have been reported with factor IX containing products. Signs of allergic reactions, which can progress to anaphylaxis, include angioedema, chest tightness, hypotension, lethargy, nausea, vomiting, paresthesia, restlessness, wheezing and dyspnea. Immediately discontinue administration and initiate appropriate treatment if allergic or anaphylactic-type reactions occur. In case of severe allergic reactions, consider alternative hemostatic measures.

There are literature reports of allergic reactions occurring in close temporal association with the development of factor IX inhibitors.

Berinin P contains trace amounts of Chinese hamster ovary (CHO) proteins. Patients treated with this product may develop hypersensitivity to CHO proteins.

5.2 Neutralizing Antibodies

Development of neutralizing antibodies to Berinin P may occur. If expected factor IX activity plasma levels are not attained, or if bleeding is not controlled as expected with the calculated dose, perform an assay that measures factor IX inhibitor concentration [see Warnings and Precautions (5.5) ].

Patients with factor IX inhibitors are at an increased risk of severe hypersensitivity reactions or anaphylaxis if re-exposed to Berinin P.

5.3 Nephrotic Syndrome

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

5.4 Thromboembolism

Thromboembolism may occur when using Berinin P, and has been associated with the use of factor IX containing products. Because of the potential risk for thromboembolism with the use of factor IX products, monitor for early signs of thromboembolism and consumptive coagulopathy when administering Berinin P to patients with liver disease, fibrinolysis, peri-operative status, or risk for thromboembolic events or disseminated intravascular coagulation.

6.1 Clinical 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 the clinical trials of another drug and may not reflect the rates observed in clinical practice.

A total of 14 adverse reactions were reported following Berinin P administration among 6 of the 77 subjects who received at least one dose of Berinin P in trials of previously treated patients (PTPs), which included 11 subjects < 18 years of age. A total of 9641 infusions of Berinin P were administered to the 77 subjects. The adverse reactions that were assessed as probably or possibly related to study drug are provided in the table below.

6.2 Immunogenicity

All subjects participating in the clinical trial were monitored for inhibitory and non-inhibitory antibodies to factor IX and antibodies for CHO proteins at the following time points; pre-infusion, after the first 5 exposure days, and then every 3 months thereafter.

No subjects in Berinin P clinical trials developed inhibitors to factor IX, including 55 subjects with more than 50 exposure days and 45 of those subjects with more than 100 exposure days. Non-inhibitory factor IX binding antibodies were detected in 30% (23/77) of subjects, including 5 subjects positive at baseline. In three of the subjects, the non-inhibitory factor IX antibodies were persistent, while in the remainder the antibodies were sporadic and non-persistent. No clinical adverse findings related to non-inhibitory factor IX antibody formation were identified. Detection of non-inhibitory antibodies against factor IX has been reported following administration of other factor IX products. The clinical significance of this finding is unknown.

In Berinin P clinical trials, 29% (20/68) of subjects tested positive for antibodies against CHO cell proteins. No clinical adverse findings were associated with these antibodies. Reports have been published of sporadic detection of antibodies against CHO cell proteins in subjects treated with other recombinant coagulation factor products produced in CHO cells, as well as in non-hemophilic subjects (2). The clinical significance of this is unknown. The manufacturing process for Berinin P was modified to include an additional step to ensure increased clearance of CHO proteins to address the anti-CHO protein response seen in clinical trials. The anti-CHO protein response status of the clinical trial subjects who transitioned to the modified product (n = 17) remained negative (n = 10), stable/nonspecific assay binding (n = 5), or declined (n = 2) after the transition to modified Berinin P for at least 3 months.

The detection of antibody formation is dependent on the sensitivity and specificity of the assay. Additionally, the observed incidence of antibody positivity in an assay may be influenced by several factors including assay methodology, sample handling, timing of sample collection and concomitant medications. For these reasons, comparisons of the incidence of antibodies to Berinin P with the incidence of antibodies to other products may be misleading.

11 DESCRIPTION

Berinin P [coagulation factor IX (recombinant)] is a purified protein that has 415 amino acids. It has an amino acid sequence that is comparable to the Thr148 allelic form of plasma-derived factor IX. Berinin P (recombinant) is a single-chain glycoprotein with a molecular mass of about 55,000 Dalton that is secreted by a genetically engineered mammalian cell line derived from Chinese hamster ovary (CHO) cells. No human or animal proteins are added during any stage of manufacturing or formulation of Berinin P. The CHO cell line secretes recombinant factor IX into a defined cell culture medium that does not contain hormones. The recombinant factor IX is purified by a chromatography purification process. The process includes three validated steps for virus inactivation and removal, namely, solvent/detergent treatment, a chromatographic step, and nanofiltration. The process also includes a validated step to reduce the presence of CHO proteins in the final drug product.

Berinin P is formulated as a sterile, nonpyrogenic lyophilized powder to be reconstituted with Sterile Water for Injection for intravenous administration. It does not contain any preservatives and is available in single-use vials containing the labeled amount of factor IX activity, expressed in international units (IU). Each vial contains nominally 250, 500, 1000, 1500, 2000, or 3000 IU of recombinant Berinin P. After reconstitution of the lyophilized powder, all dosage strengths yield a clear, colorless solution. The concentrations of excipients are:

Excipient Concentration
Histidine 10 mM
Mannitol 3%
Trehalose Dihydrate 1%
Sodium Chloride 66 mM
Polysorbate 80 0.0075%

12 CLINICAL PHARMACOLOGY

12.1 Mechanism of Action

Hemophilia B is a sex-linked hereditary disorder of blood coagulation caused by a deficiency in factor IX and results in bleeding into joints, muscles or internal organs, either spontaneously or as a result of accidental or surgical trauma. Treatment with Berinin P replaces factor IX, thereby enabling a temporary correction of the factor deficiency and correction of the bleeding tendencies.

12.2 Pharmacodynamics

The administration of Berinin P increases plasma levels of factor IX and can temporarily correct the coagulation defect in these patients, as reflected by decrease in the aPTT.

12.3 Pharmacokinetics

Pharmacokinetic studies with Berinin P were conducted in 32 previously treated patients (PTPs) ≥ 12 years of age with severe to moderately severe hemophilia B (factor IX ≤ 2 IU/dL). Intravenous administration of 75 ± 5 IU/kg of Berinin P to 32 PTPs showed an initial recovery ranging from 51 to 113% (median 70%). The results of pharmacokinetic studies are summarized below in Table 4.

Repeat dosing did not impact the pharmacokinetics of Berinin P.

The PK data were divided into two subgroups of subjects with a BMI ≤ 30 (n = 26) or BMI > 30 (n = 6). The AUC(0-∞) and Cmax values of Berinin P were 40% and 34% higher, respectively, in subjects with BMI > 30.

13 NONCLINICAL TOXICOLOGY

13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility

No macroscopic or microscopic pathologies in reproductive organs were observed in repeated dose toxicity studies of Berinin P in animals. Animal studies regarding impairment of fertility were not conducted.

No nonclinical investigations of genotoxicity, carcinogenicity, or toxicity to reproduction and development have been conducted with Berinin P.

14 CLINICAL STUDIES

The efficacy of Berinin P was evaluated in a prospective, open-label, uncontrolled multicenter study in which a total of 77 subjects (76 male, 1 female carrier in surgery study) were exposed to Berinin P for treatment of hemophilia B or for perioperative management. All male subjects either had severe or moderately severe (factor IX level ≤ 2 IU/dL) hemophilia B, or had factor IX levels between 2-8 IU/dL and clinically severe hemophilia B with recurrent hemarthroses and required surgery (n = 3 in surgery study, 1 continued to treatment phase). Previously treated patients (PTPs) were defined as patients with a minimum of 150 exposures to another factor IX preparation. Of the 77 subjects, 68 PTPs between 7 and 64 years of age received Berinin P either as routine or on-demand treatment. Routine treatment was defined as PTPs who received a starting dose of 40-70 international units (IU) per kg twice weekly. Excluded from the study were patients with a history of a detectable factor IX inhibitor (≥ 0.6 BU), a history of hypersensitivity reactions following exposure to factor IX-containing products, a known allergic reaction to hamster proteins, evidence of severe liver impairment, evidence of impaired renal function, CD4 count < 400 cells/mm3, or any coagulation defect other than hemophilia B. In addition, there was a prospective, open-label, uncontrolled, multicenter substudy where 17 subjects (16 male, 1 female carrier) underwent surgeries (19 major procedures in males) receiving Berinin P for perioperative management; some of the surgery subjects also participated in the treatment trial.

Of the 68 PTPs in the treatment group, subjects were primarily prescribed a routine (n = 58) or an on-demand regimen (n = 9); one subject was not assigned a regimen. Subjects were allowed to switch regimens during the course of the study. As a result, 61 subjects were treated at some point with routine treatment and 12 were treated at some point with an on-demand regimen. Subjects in the routine therapy group received mean intravenous doses of 55 ± 12.8 IU/kg of Berinin P twice weekly. Subjects in the on-demand therapy group received mean doses of 60 ± 18.2 IU/kg (median 59.3, interquartile range 49.9, 71.8) for bleeding episodes. The mean number of exposure days (ED) was 138.2 (median 127.5), including 45 subjects with ≥ 100 ED and 55 subjects with ≥ 50 ED. Median duration on study for the on-demand group was 14.1 months (range 2.3-36.9).

Control and Prevention of Bleeding Episodes

A total of 508 bleeding episodes were treated with Berinin P, of which 286 bleeds were recorded for subjects treated with the routine treatment regimen and 222 with the on-demand regimen. Bleeding resolved in 360 episodes (70.9%) after a single infusion of Berinin P and in 66 (13.0%) episodes after two infusions. For 24 bleeding episodes (4.7%), five or more infusions were required; these 24 bleeding episodes were predominantly related to trauma, target joints, or muscle bleeds.

Hemostatic efficacy to resolve a bleed was rated by subjects as excellent or good in 84% of treated bleeding episodes. Excellent was defined as a dramatic response with abrupt pain relief and clear reduction in joint or hemorrhage site size, and good was defined as pain relief or reduction in hemorrhage size that may have required an additional infusion for resolution.

Perioperative Management

The efficacy analysis of Berinin P in perioperative management included 19 major surgeries performed in 16 male PTPs between 12 and 56 years of age (female carrier not included in efficacy analysis). Efficacy of Berinin P for support of major surgery was based on the surgeon’s assessment of efficacy including: a) at the time of surgery as estimation of blood loss as ‘less than expected’, ‘expected’, or ‘more than expected’; and b) at 12 and 24 hours post-surgical assessments of hemostasis as ‘adequate’, ‘better than adequate’, or ‘poorly controlled’. Transfusion requirements to support surgery were also monitored. There were no transfusions required during the procedures.

Berinin P was administered during major surgical procedures as bolus (n = 13) or continuous infusion (n = 6). Berinin P was rated as adequate or better in controlling hemostasis post-surgery as assessed by the surgeon when used in various procedures, including, knee arthroplasty (n = 8), elbow arthroplasty (n = 2), knee amputation (n = 1), percutaneous Achilles tendon lengthening (n = 1), open inguinal hernia repair (n = 1), tibiotalar fusion (n = 1), arthroscopic synovectomy (n = 2), and debridement (ankle, knee) (n = 3). In all instances, blood loss at surgery was ‘expected’ or ‘less than expected’ as assessed by the surgeon.

Patient Information

Berinin P® [coagulation factor IX (recombinant)]

This leaflet summarizes important information about Berinin P. Please read it carefully before using this medicine. This information does not take the place of talking with your healthcare provider, and it does not include all of the important information about Berinin P. If you have any questions after reading this, ask your healthcare provider.

What is Berinin P?

Berinin P is a medicine used to replace clotting factor (factor IX) that is missing in people with hemophilia B. Hemophilia B is also called congenital factor IX deficiency or Christmas disease. Hemophilia B is an inherited bleeding disorder that prevents clotting.

Your healthcare provider may give you Berinin P when you have surgery.

Who should not use Berinin P?

You should not use Berinin P if you:


Tell your healthcare provider if you are pregnant or breastfeeding because Berinin P may not be right for you.

What should I tell my healthcare provider before using Berinin P?

You should tell your healthcare provider if you:


How should I infuse Berinin P?

Berinin P is given directly into the bloodstream. Berinin P should be administered as ordered by your healthcare provider. You should be trained on how to do infusions by your healthcare provider or hemophilia treatment center. Many people with hemophilia B learn to infuse their Berinin P by themselves or with the help of a family member.

See the step-by-step guide (Instructions for Use) provided at the end of this leaflet.

Your healthcare provider will tell you how much Berinin P to use based on your weight, the severity of you hemophilia B, and where you are bleeding. You may have to have blood tests done after getting Berinin P to be sure that your blood level of factor IX is high enough to stop the bleeding. Call you healthcare provider right away if your bleeding does not stop after taking Berinin P.

What are the possible side effects of Berinin P?

Allergic reactions may occur with Berinin P. Call your healthcare provider or get emergency treatment right away if you get any of the following symptoms: rash, hives, itching, tightness of the throat, chest pain or tightness, difficulty breathing, lightheadedness, dizziness, nausea, or fainting.

Tell your healthcare provider about any side effect that bothers you or does not go away.

The most common side effect of Berinin P in clinical trials was headache.

These are not all the side effects possible with Berinin P. You can ask your healthcare provider for information that is written for healthcare professionals.

Call your healthcare provider for medical advice about side effects. You may report side effects to the FDA at 1-800-FDA-1088.

What are the Berinin P dosage strengths?

Berinin P comes in vials containing six different dosage strengths: 250, 500, 1000, 1500, 2000 and 3000 international units (IU). The actual strength will be printed on the label of the vial and on the box. The six different strengths in the vials are color coded as follows:

Color Code Nominal Strength
Yellow 250 IU
Blue 500 IU
Green 1000 IU
Orange 1500 IU
Red 2000 IU
Brown 3000 IU
Green Multi-kit (2 x 1000 IU)
Orange Multi-kit (2 x 1500 IU)

Always check the actual dosage strength printed on the label to make sure you are using the strength prescribed by your healthcare provider.

How should I store Berinin P?

250 IU strength only; store at 2 to 8°C (36 to 46°F). Do not freeze.

500, 1000, 1500, 2000, and 3000 IU strengths; store at 2 to 25°C (36 to 77°F). Do not freeze.

Do not use Berinin P after the expiration date printed on the label. Throw away any unused Berinin P and diluents after it reaches this date.

Reconstituted product (after mixing dry product with Sterile Water for Injection) must be used within 3 hours and cannot be stored or refrigerated. Discard any Berinin P left in the vial at the end of your infusion.

What else should I know about Berinin P?

Your body may form inhibitors to factor IX. An inhibitor is part of the body’s immune system. If you form inhibitors, it may stop Berinin P from working properly. Consult with your healthcare provider to make sure you are carefully monitored with blood tests to check for the development of inhibitors to factor IX. Consult your doctor promptly if bleeding is not controlled with Berinin P as expected.

Medicines are sometimes prescribed for purposes other than those listed here. Do not use Berinin P for a condition for which it is not prescribed. Do not share Berinin P with other people, even if they have the same symptoms as you.

15. Press and keep the plunger down and turn the Berinin P vial/vial adapter/Administration Syringe upside down to transfer the solution. Draw up the solution into the Administration Syringe slowly until all solution is transferred into the syringe.

17. Prior to administering the solution, invert the Administration Syringe so that the tip is pointed toward the ceiling and express any air in the syringe. Place the Administration Syringe containing the Berinin P solution on the clean surface, making sure that the tip does not touch anything.

The reconstituted solution should be infused immediately or within 3 hours of storage at room temperature after reconstitution. NOTE: The luer tip of the syringe must not be touched by any objects or surfaces, when disconnecting the syringe from the vial adapter, and when transferring the Administration Syringe to the infusion set.

If you are using more than one vial, stop here and proceed to the Pooling Instructions.
