PROFESSIONAL CONSUMER SIDE EFFECTS

Drug Description

What is Novoeight and how is it end?

Novoeight, Antihemophilic Factor (Recombinant) is a recombinant (r) analogue of human coagulation factor VIII (FVIII) used in patients with hemophilia A (congenital factor VIII deficiency or classic hemophilia) for control and prevention of bleeding episodes, perioperative management, and to prevent or reduce the frequency of bleeding episodes. Novoeight is not indicated for the treatment of von Willebrand disease.

What are side effects of Novoeight?

Common side effects of Novoeight include:

injection site reactions such as swelling or itching,
increased hepatic enzymes, and
fever.

Tell your doctor if you experience serious side effects of of Novoeight including:

allergic reactions (rash, itching, hives, difficulty breathing or swallowing, tightness in the chest, swelling in the lips or tongue),
dizziness,
lightheadedness,
fainting,
pale and cold skin,
fast heartbeat,
red or swollen face or hands,
severe nausea or vomiting, or
shortness of breath.

DESCRIPTION

Novoeight® is formulated as a sterile, non-pyrogenic, lyophilized powder for intravenous injection after reconstitution with the diluent (0.9% sodium chloride). Novoeight® is available in single-dose vials that contain nominally 250, 500, 1000, 1500, 2000 or 3000 international units (IU) per vial. When reconstituted with the appropriate volume of diluent, the product contains the following components per mL: 18 mg sodium chloride, 1.5 mg L-histidine, 3 mg sucrose, 0.1 mg polysorbate 80, 0.055 mg L-methionine and 0.25 mg calcium chloride dihydrate. The product contains no preservative. Each vial of Novoeight® is labeled with the actual rFVIII activity expressed in IU determined by the one-stage clotting assay, using a reference material calibrated against a World Health Organization (WHO) International Standard for FVIII Concentrates. One IU, as defined by the WHO standard for human FVIII, is approximately equal to the level of FVIII activity in 1 mL of fresh pooled human plasma. The specific activity of Novoeight® is approximately 8340 IU per milligram of protein.

The active ingredient in Novoeight® is a recombinant (r) analogue of human coagulation factor VIII (FVIII) with a molecular mass of 166 kDa, calculated excluding post-translational modifications. The rFVIII molecule in Novoeight® is a glycoprotein containing a heavy chain and a light chain, with 21 of the 908 amino acids of the B-domain of endogenous FVIII connected to the C-terminus of the heavy chain. Once activated, the resulting rFVIIIa has a comparable structure to the endogenous FVIIIa.

Novoeight® is synthesized by a genetically engineered Chinese hamster ovary (CHO) cell line which secretes rFVIII into the cell culture medium. The rFVIII protein is purified using a series of chromatography steps, one of which is the use of an immunoaffinity column in which a monoclonal antibody, produced in CHO cells and directed against FVIII, is employed to selectively isolate the rFVIII from the medium. The production process includes two dedicated viral clearance steps - a detergent treatment step for inactivation and a 20-nm filtration step for removal of viruses. No additives of human or animal origin are used in the cell culture, purification and formulation of Novoeight®.

Indications & Dosage

INDICATIONS

Novoeight, Antihemophilic Factor (Recombinant), is a human antihemophilic factor (human blood coagulation factor VIII (FVIII)) indicated for use in adults and children with hemophilia A for:

On-demand treatment and control of bleeding episodes
Perioperative management
Routine prophylaxis to reduce the frequency of bleeding episodes

Novoeight is not indicated for the treatment of von Willebrand disease.

DOSAGE AND ADMINISTRATION

For intravenous injection after reconstitution only.

Dose

Dosage and duration of treatment depend on the severity of the factor VIII deficiency, on the location and extent of bleeding, and the patientâ€™s clinical condition. Careful monitoring of replacement therapy is necessary in cases of major surgery or life-threatening bleeding episodes.
Each vial of Novoeight contains the labeled amount of recombinant factor VIII in international units (IU). One IU of factor VIII activity corresponds to the quantity of factor VIII in one milliliter of normal human plasma. The calculation of the required dosage of factor VIII is based on the empirical finding that one IU of factor VIII per kg body weight raises the plasma factor VIII activity by two IU/dL. This relationship causes a factor of 0.5 to be present in the dose calculation formula shown below.
The required dosage can be determined using the following formula: Dosage (IU) = Body Weight (kg) Ã— Desired Factor VIII Increase (IU/dL or % normal) Ã— 0.5

The final dose calculated is expressed as IU

Base the dose and frequency of Novoeight on the individual clinical response. Patients may vary in their pharmacokinetic and clinical responses [See CLINICAL PHARMACOLOGY].

Side Effects & Drug Interactions

SIDE EFFECTS

The most frequently reported adverse reactions observed in clinical trials (≥ 1%) were injection site reactions, and pyrexia.

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

During the clinical development of Novoeight, 301 male patients (242 previously treated patients (PTPs); exposed to a factor VIII-containing product for ≥150 days and 59 Previously Untreated Patients (PUPs)) with severe hemophilia A (factor VIII level ≤1%) received at least one dose of Novoeight as part of either routine prophylaxis, on-demand treatment of bleeding episodes, perioperative management of major and minor surgical, dental, or other invasive procedures, Immune Tolerance Induction (ITI) or pharmacokinetic evaluation of Novoeight with more than 140,000 exposure days (corresponding to over 900 patient years). During prophylaxis treatment subjects received a median of 468 injections of Novoeight (range 1-1317).

Table 4: Summary of Adverse Reactions (ARs ) with a Frequency ≥ 1% in 301 Subjects

MedDRA System Organ class	Adverse Reactions	Frequency N (%)
General disorders and administration site conditions	Pyrexia	3 (1.0%)
General disorders and administration site conditions	Injection site reaction	3 (1.0%)

Immunogenicity

Subjects were monitored for neutralizing antibodies to factor VIII and binding antibodies to CHO and murine protein. No PTPs developed confirmed neutralizing antibodies to factor VIII. One twenty-two month old previously treated child had a positive neutralizing antibody to factor VIII of 1.3 [BU] in the Bethesda assay after 15 exposure days that was not confirmed when checked after 20 exposure days. In vivo recovery was normal for this child and no clinical adverse findings were observed. In the completed main phase of the clinical trial in PUPs, 24 of 56 (42.9%) patients developed inhibitors with a mean of 14.1 exposure days at the time of the first positive inhibitor test; 15 (26.8%) PUPs developed high titer (≥ 5 BU) inhibitors. High risk genetic mutations were identified in 91.7% of the overall inhibitors and 93.3% of the high titer inhibitors.

No patients developed de novo anti-murine antibodies. Nineteen subjects were positive for anti-Chinese hamster ovary (CHO) cell protein antibodies. Two of these subjects changed from anti-CHO negative to anti-CHO positive and 6 subjects changed from anti-CHO positive to anti-CHO negative. The remaining 11 subjects were either positive throughout the trials (n=6), negative at baseline and end-of trial but with transient positive samples (n=2), or positive at baseline and end-of trial but with negative samples in between (n=3). No clinical adverse findings were observed in any of these subjects.

The detection of antibody formation is highly dependent on the sensitivity and specificity of the assay. Additionally, the observed incidence of antibody (including neutralizing antibody) positivity in an assay may be influenced by several factors, including assay methodology, sample handling, timing of sample collection, concomitant medications, and underlying disease. For these reasons, it may be misleading to compare the incidence of antibodies to Novoeight with the incidence of antibodies to other products.

Postmarketing Experience

Adverse reactions reported during post marketing period were similar in nature to those observed during clinical trials.

DRUG INTERACTIONS

No Information provided

Warnings & Precautions

WARNINGS

Included as part of the PRECAUTIONS section.

PRECAUTIONS

Hypersensitivity Reactions

Hypersensitivity reactions, including anaphylaxis, are possible with Novoeight. Novoeight contains trace amounts of hamster proteins. Patients treated with this product may develop hypersensitivity to these non-human mammalian proteins. Early signs of hypersensitivity reactions that can progress to anaphylaxis include angioedema, chest tightness, dyspnea, wheezing, urticaria, and pruritus. Immediately discontinue administration and initiate appropriate treatment if allergic- or anaphylactic-type reactions occur.

Neutralizing Antibodies

Formation of neutralizing antibodies (inhibitors) to factor VIII can occur following administration of Novoeight. Previously untreated patients (PUPs) are at greatest risk for inhibitor development with all factor VIII products. Inhibitors have been reported following administration of Novoeight in PUPs [see ADVERSE REACTIONS]. Monitor all patients for the development of inhibitors by appropriate clinical observation and laboratory testing. If the expected plasma levels of factor VIII activity are not attained, or if bleeding is not controlled with an appropriate dose, perform testing for factor VIII inhibitors.

Monitoring Laboratory Tests

Monitor plasma factor VIII activity levels by the one-stage clotting assay or the chromogenic substrate assay to confirm that adequate factor VIII levels have been achieved and maintained, when clinically indicated. [See DOSAGE AND ADMINISTRATION]
Perform assay to determine if factor VIII inhibitor is present if expected plasma factor VIII activity levels are not attained, or if bleeding is not controlled with the expected dose of Novoeight. Determine inhibitor levels in Bethesda Units.

Patient Counseling Information

Advise patients to read the FDA-approved patient labeling (Patient Information and Instructions for Use).
Allergic-type hypersensitivity reactions or anaphylaxis are possible with use of Novoeight. Inform patients of the early signs of hypersensitivity reactions including rash, hives, itching, facial swelling, tightness of the chest and wheezing. Advise patients to discontinue use of Novoeight immediately and contact their physician, and go to the emergency department if these symptoms occur.
Advise patients to contact their physician or treatment facility for further treatment and/or assessment if they experience a lack of a clinical response to factor VIII replacement therapy, as this may be a manifestation of an inhibitor.
Advise patients to consult with their healthcare provider prior to traveling. While traveling, patients should be advised to bring an adequate supply of Novoeight based on their current treatment regimen.

Nonclinical Toxicology

Carcinogenesis, Mutagenesis, Impairment Of Fertility

Long-term studies in animals to evaluate the carcinogenic potential of Novoeight, or studies to determine the effects of Novoeight on genotoxicity or fertility have not been performed. An assessment of the carcinogenic potential of Novoeight was completed, and no carcinogenic risk from product use has been identified.

Use In Specific Populations

Pregnancy

Risk Summary

As hemophilia mainly affects males, there are no adequate and well-controlled studies using Novoeight in pregnant women to determine whether there is a drug-associated risk. Animal reproduction studies have not been conducted with Novoeight. 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. There is no reliable data on the incidences specific to the hemophilia A population.

Lactation

Risk Summary

There is no information regarding the presence of Novoeight 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 motherâ€™s clinical need for Novoeight and any potential adverse effects on the breastfed infant from Novoeight or from the underlying maternal condition.

Pediatric Use

Children have shorter half-life and lower recovery of factor VIII than adults. Because clearance (based on per kg body weight) has been demonstrated to be higher in the pediatric population, higher or more frequent dosing based on body weight may be needed. [See CLINICAL PHARMACOLOGY]

Safety and efficacy studies have been performed in 146 pediatric patients <18 years of age. Ninety (including all 59 PUPs) of these subjects (62%) were <6 years of age, 32 (22%) were 6 to <12 years of age, and 24 (16%) were adolescents (12 to <18 years of age). Subjects during routine prophylaxis and treatment of bleeds received Novoeight at the dose levels described in Tables 1 and 3. A total of 1290 bleeds in 127 subjects were treated with Novoeight. The majority of the bleeds 1162 (90%) were of mild/moderate severity. Of these 1290 bleeds, 1140 (88%) were rated excellent or good in their response to treatment with Novoeight and in 17 (1%) the response to treatment was unknown. A total of 1100 (85%) of the bleeds were resolved with one or two injections of Novoeight. Routine prophylactic treatment has been shown to reduce joint bleeding. [See Clinical Studies]

Geriatric Use

Clinical studies of Novoeight did not include sufficient numbers of patients aged 65 and over to determine whether they respond differently from younger patients.

Obesity

In the extension trial, in six adult patients with body mass index (BMI) ≥ 30 kg/m², the AUC was higher and clearance lower than in patients with BMI < 30 kg/m². There is insufficient data to recommend specific dose adjustments for patients with BMI ≥ 30 kg/m². Adjust dose as necessary and per prescriberâ€™s discretion for patients with BMI ≥ 30 kg/m². [See CLINICAL PHARMACOLOGY].

Overdosage & Contraindications

OVERDOSE

No information provided.

CONTRAINDICATIONS

Novoeight® is contraindicated in patients who have had life-threatening hypersensitivity reactions, including anaphylaxis, to Novoeight® or its components (including traces of hamster proteins).

Clinical Pharmacology

CLINICAL PHARMACOLOGY

Mechanism Of Action

Novoeight temporarily replaces the missing clotting factor VIII that is needed for effective hemostasis.

Pharmacodynamics

The activated partial thromboplastin time (aPTT) is prolonged in patients with hemophilia A. Determination of aPTT is a conventional in vitro assay for the biological activity of FVIII. Treatment with Novoeight normalizes the aPTT over the effective dosing period.

Pharmacokinetics

All pharmacokinetic studies with Novoeight were conducted in previously treated patients with severe hemophilia A (factor VIII ≤ 1%). Analysis of plasma samples was conducted using both the one-stage clotting assay and the chromogenic assay.

In a multi-center, multi-national, open-label, single dose pharmacokinetic study, 23 patients with severe hemophilia A received 50 international units/kg of Novoeight intravenously. Two patients were below the age of 18 years (13 and 17 years). The pharmacokinetic parameters for 20 patients who completed the study are summarized in Table 5.

The pharmacokinetic parameters were comparable between younger (0 to < 6 years) and older (6 to < 12 years) children. The mean clearance of Novoeight in younger and older children was 67% and 34% higher (based on per kg body weight) than in adults (3.74 mL/h/kg) when using the clotting assay, and 60% and 29% higher than in adults (2.87 mL/h/kg) when using the chromogenic assay. The mean half-life of Novoeight in younger and older children was 29% and 26% shorter than in adults (10.8 hours) when using the clotting assay, and 16% and 21% shorter than in adults (12 hours) when using the chromogenic assay.

Clinical Studies

Four multi-center, open-label, non-controlled trials have been conducted to evaluate the safety and efficacy of Novoeight in the on-demand treatment and control of breakthrough bleeds, routine prophylaxis and perioperative management in patients with hemophilia A. Three of these trials were performed in PTPs (two trials and one extension trial) and the fourth in PUPs. The analysis included 297 exposed subjects: 175 previously treated adolescents or adult subjects from the age of 12 years (≥150 exposure days), 63 previously treated pediatric subjects below the age of 12 years (≥50 exposure days) and 59 PUPs below 6 years of age. Immunocompetent patients with severe hemophilia A (factor VIII activity ≤1%) and no history of FVIII inhibitors were eligible for the trials. Subjects during routine prophylaxis and treatment of bleeds received Novoeight at the dose levels described in Tables 1 and 3. Breakthrough bleeds were treated at the investigatorâ€™s discretion aiming for a FVIII activity level above 0.5 IU/mL. Treatment during surgery was at the investigatorâ€™s discretion aiming for a FVIII trough activity level above 0.5 IU/mL.

On-Demand Treatment And Control Of Bleeding Episodes

A total of 3153 bleeds in 260 subjects were treated with Novoeight. The majority of the bleeds (90%) were of mild/moderate severity, 54% of the bleeds were spontaneous and 67% of the bleeds were localized in joints.

An overall assessment of efficacy was performed by the subject (for home treatment) or study site investigator (for treatment under medical supervision) using a four-point scale of excellent, good, moderate, or none. If the hemostatic response was rated as “excellent” or “good”, the treatment of the bleed was considered a success. If the hemostatic response was rated as “moderate or none” the treatment was considered a failure. Of these 3,153 bleeds, 2,809 (89%) were rated excellent or good in their response to treatment with Novoeight, 274 (9%) were rated as moderate, 25 (0.8%) were rated as having no response and for 45 (1%) the response to treatment was unknown. A total of 2,794 (89%) of the bleeds were resolved with one or two injections of Novoeight.

Of the 238 PTPs, 206 patients experienced 2,793 bleeds of which 2,492 (89%) were rated excellent or good in their response to treatment with Novoeight, 244 (9%) were moderate, 23 (0.8%) were rated as having no response, and for 34 (1%) the response to treatment was unknown. Of the 2,793 reported bleeds observed in 206 of the patients, 2,504 (90%) of the bleeds were resolved with 1â€“2 injections of Novoeight. The majority of the bleeds were of mild/moderate severity.

Of the 59 PUPs, 54 patients experienced 360 bleeds of which 317 (88%) were rated excellent or good in their response to treatment with Novoeight, 30 (8%) were moderate, 2 (0.6%) were rated as having no response, and for 11 (3%) the response to treatment was unknown. Of the 360 reported bleeds observed in 54 of the patients, 290 (81%) of the bleeds were resolved with 1â€“2 injections of Novoeight. The majority of the bleeds were of mild/moderate severity and the most frequent bleeds were subcutaneous.

Routine Prophylaxis

In the two trials, one trial including 150 adult/adolescent subjects (6 months duration) and the other trial including 63 pediatric subjects (4 months duration) received Novoeight for routine prophylaxis (Table 8). These previously treated patients received prophylaxis treatment every other day or three times weekly at the dose levels described in Table 3.

In the trial with previously untreated patients, 56 subjects below 6 years of age received Novoeight for routine prophylaxis. The median annualized bleeding rate in the previously untreated patients was 2.9 (IQR 5.4) and the mean (95%CI) was 4.4 (3.3; 5.8).

Perioperative Management

A total of 30 surgeries were performed in 25 previously treated subjects between 8 and 58 years of age, of which 26 were major surgeries (20 orthopaedic, 5 non-orthopaedic and a circumcision), and 4 were minor (2 dental, 1 circumcision and 1 insertion of port-a-cath).

The investigatorâ€™s ratings of intra- and post-operative quality of hemostasis for these subjects were “excellent” or “good” for all cases.

Medication Guide

PATIENT INFORMATION

Novoeight®
(NO-vo-eyt) Antihemophilic Factor (Recombinant)

Read the Patient Product Information and the Instructions For Use that come with Novoeight before you start taking this medicine and each time you get a refill. There may be new information.

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 Novoeight after reading this information, ask your healthcare provider.

What is the most important information I need to know about Novoeight?

Do not attempt to do an infusion yourself unless you have been taught how by your healthcare provider or hemophilia center.

You must carefully follow your healthcare provider's instructions regarding the dose and schedule for infusing Novoeight so that your treatment will work best for you.

What is Novoeight?

Novoeight is an injectable medicine used to replace clotting factor VIII that is missing in patients with hemophilia A. Hemophilia A is an inherited bleeding disorder that prevents blood from clotting normally.

Novoeight is used to control and prevent bleeding in people with hemophilia A.

Your healthcare provider may give you Novoeight when you have surgery.

Novoeight is not used to treat von Willebrand Disease.

Who should not use Novoeight?

You should not use Novoeight if you

are allergic to factor VIII or any of the other ingredients of Novoeight
if you are allergic to hamster proteins

Tell your healthcare provider if you are pregnant or nursing because Novoeight might not be right for you.

What should I tell my healthcare provider before I use Novoeight?

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.
Are pregnant or planning to become pregnant.
Have been told that you have inhibitors to factor VIII.

How should I use Novoeight?

Treatment with Novoeight should be started by a healthcare provider who is experienced in the care of patients with hemophilia A.

Novoeight is given as an injection into the vein.

You may infuse Novoeight 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 A learn to infuse the medicine by themselves or with the help of a family member.

Your healthcare provider will tell you how much Novoeight to use based on your weight, the severity of your hemophilia A, and where you are bleeding.

You may need to have blood tests done after getting Novoeight to be sure that your blood level of factor VIII is high enough to clot your blood. This is particularly important if you are having major surgery.

Your healthcare provider will calculate your dose of Novoeight (in international units, IU) depending on your condition and body weight.

Call your healthcare provider right away if your bleeding does not stop after taking Novoeight.

Development of factor VIII inhibitors

Your body can also make antibodies called “inhibitors” against Novoeight, which may stop Novoeight from working properly. If your bleeding is not adequately controlled, it could be due to the development of factor VIII inhibitors. This should be checked by your healthcare provider. You might need a higher dose of Novoeight or even a different product to control bleeding. Do not increase the total dose of Novoeight to control your bleeding without consulting your healthcare provider.

Use in children

Novoeight can be used in children. Your healthcare provider will decide the dose of Novoeight you will receive.

If you forget to use Novoeight

Do not inject a double dose to make up for a forgotten dose. Proceed with the next injections as scheduled and continue as advised by your healthcare provider.

If you stop using Novoeight

If you stop using Novoeight you are not protected against bleeding. Do not stop using Novoeight without consulting your healthcare provider.

If you have any further questions on the use of this product, ask your healthcare provider.

What if I take too much Novoeight?

Always take Novoeight exactly as your healthcare provider has told you. You should check with your healthcare provider if you are not sure. If you inject more Novoeight than recommended, tell your healthcare provider as soon as possible.

What are the possible side effects of Novoeight?

Common Side Effects Include:

Inhibitors in patients who were not previously treated with Factor VIII products
Swelling or itching at the location of injection
Fever

Other Possible Side Effects:

You could have an allergic reaction to coagulation factor VIII products. Call your healthcare provider right away and stop treatment if you get any of the following signs of an allergic reaction:

tightness of the chest or throat, difficulty swallowing
swelling of the lips and tongue
light-headedness, dizziness or loss of consciousness
pale and cold skin, fast heart beat which may be signs of low blood pressure
red or swollen face or hands

These are not all of the possible side effects from Novoeight. Ask your healthcare provider for more information. You are encouraged to report side effects to FDA at 1-800-FDA-1088.

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

What are the Novoeight dosage strengths?

Instructions on how to use Novoeight® MixPro®

READ THESE INSTRUCTIONS CAREFULLY BEFORE USING NOVOEIGHT®.

Novoeight® is supplied as a powder. Before injection (administration) it must be mixed (reconstituted) with the liquid diluent supplied in the syringe. The liquid diluent is a sodium chloride solution. The mixed Novoeight® must be injected into your vein (intravenous injection). The equipment in this package is designed to mix and inject Novoeight®.

You will also need an infusion set (tubing and butterfly needle), sterile alcohol swabs, gauze pads, and bandages.

Donâ€™t use the equipment without proper training from your doctor or nurse.

Always wash your hands and ensure that the area around you is clean.

When you prepare and inject medication directly into the veins, it is important to use a clean and germ free (aseptic) technique. Improper technique can introduce germs that can infect the blood.

Donâ€™t open the equipment until you are ready to use it.

Donâ€™t use the equipment if it has been dropped, or if it is damaged. Use a new package instead.

Donâ€™t use the equipment if it is expired. Use a new package instead. The expiration date is printed on the outer carton and on the vial, the vial adapter and the pre-filled syringe.

Donâ€™t use the equipment if you suspect it is contaminated. Use a new package instead.

Donâ€™t dispose of any of the items until after you have injected the mixed solution.

The equipment is for single use only. Single-dose vial. Discard unused portion.

Content

The package contains:

Vial with Novoeight® powder
Vial adapter
Pre-filled syringe with diluents
Plunger rod (placed under the syringe)

Overview

1. Prepare the vial and the syringe

Take out the number of Novoeight® packages you need.
Check the expiry date.
Check the name and the color of the package, to make sure it contains the correct product.
Wash your hands and dry them properly using a clean towel or air dry.
Take the vial, the vial adapter and the pre-filled syringe out of the carton. Leave the plunger rod untouched in the carton.
Bring the vial and the pre-filled syringe to room temperature. You can do this by holding them in your hands until they feel as warm as your hands.

Prepare the vial and the syringe - Illustration

Remove the plastic cap from the vial. If the plastic cap is loose or missing, donâ€™t use the vial.
Wipe the rubber stopper with a sterile alcohol swab and allow it to air dry for a few seconds before use to ensure that it is as germ free as possible.
Donâ€™t touch the rubber stopper with your fingers as this can transfer germs.

2. Attach the vial adapter

Remove the protective paper from the vial adapter. Donâ€™t take the vial adapter out of the protective cap with your fingers. If you touch the spike on the vial adapter germs from your fingers can be transferred. If the protective paper is not fully sealed or if it is broken, donâ€™t use the vial adapter.

Place the vial on a flat and solid surface.
Turn over the protective cap, and snap the vial adapter onto the vial. Once attached, donâ€™t remove the vial adapter from the vial.

Lightly squeeze the protective cap with your thumb and index finger as shown. Remove the protective cap from the vial adapter.

Donâ€™t lift the vial adapter from the vial when removing the protective cap.

4. Mix the powder with the diluents

Hold the pre-filled syringe slightly tilted with the vial pointing downwards.
Push the plunger rod to inject all the diluent into the vial.

Keep the plunger rod pressed down and swirl the vial gently until all the powder is dissolved. Donâ€™t shake the vial as this will cause foaming.
Check the mixed solution. It must be clear to slightly opalescent (slightly unclear). If you notice visible particles or discoloration, donâ€™t use it. Use a new package instead.

Novoeight® is recommended to be used immediately after it is mixed. This is because if left, the medicine may no longer be sterile and could cause infections.

If you cannot use the mixed Novoeight® solution immediately, it must be used within 4 hours when stored at <86°F (30°C) or within 2 hours when stored between 86°F (30°C) to 104°F (40°C). Store the reconstituted product in the vial.

Do not freeze mixed Novoeight® solution or store it in syringes.

Keep mixed Novoeight® solution out of direct light.

If your dose requires more than one vial, repeat step A to J with additional vials, vial adapters and pre-filled syringes until you have reached your required dose.

Keep the plunger rod pushed completely in.
Turn the syringe with the vial upside down.
Stop pushing the plunger rod and let it move back on its own while the mixed solution fills the syringe.
Pull the plunger rod slightly downwards to draw the mixed solution into the syringe.
In case you only need part of the entire vial, use the scale on the syringe to see how much mixed solution you withdraw, as instructed by your doctor or nurse.
While holding the vial upside down, tap the syringe gently to let any air bubbles rise to the top.
Push the plunger rod slowly until all air bubbles are gone.

Caution: The pre-filled diluent syringe is made of glass with an internal tip diameter of 0.037 inches, and is compatible with a standard Luer-lock connector.

The use of these needleless connectors can damage the connector and affect administration.

To administer Novoeight through incompatible needleless connectors, withdraw reconstituted product into a standard 10 mL sterile Luer-lock plastic syringe.

If you have encountered any problems with attaching the pre-filled sodium chloride diluent syringe to any Luer- lock compatible device, please contact Novo Nordisk at (844) 303-4448.

5. Inject the mixed solution

Novoeight® is now ready to inject into your vein.

Do not mix Novoeight® with any other intravenous infusions or medications.
Inject the mixed solution slowly over 2 to 5 minutes as instructed by your doctor or nurse.

Injecting the solution via a central venous access device (CVAD) such as a central venous catheter or subcutaneous port:

Use a clean and germ free (aseptic) technique. Follow the instructions for proper use for your connector and central venous access device in consultation with your doctor or nurse.
Injecting into a CVAD may require using a sterile 10 mL plastic syringe for withdrawal of the mixed solution and injection.
If necessary, use 0.9% Sodium Chloride Injection, USP to flush the CVAD line before or after Novoeight® injection.

The peel-off label found on the Novoeight® vial can be used to record the lot number.

Disposal

After injection, safely dispose of all unused Novoeight® solution, the syringe with the infusion set, the vial with the vial adapter, and other waste materials in an appropriate container for throwing away medical waste.

Donâ€™t throw it out with the ordinary household trash.

Donâ€™t disassemble the vial and vial adapter before disposal.

Donâ€™t reuse the equipment.
