Generic Name: interferon beta-1a
Dosage Form: injection, solution

Indications and Usage for Avonex

Avonex (interferon beta-1a) is indicated for the treatment of patients with relapsing forms of multiple sclerosis to slow the accumulation of physical disability and decrease the frequency of clinical exacerbations. Patients with multiple sclerosis in whom efficacy has been demonstrated include patients who have experienced a first clinical episode and have MRI features consistent with multiple sclerosis.

Avonex Dosage and Administration

Dosing Information

Avonex is administered intramuscularly.

The recommended dose is 30 micrograms once a week. To reduce the incidence and severity of flu-like symptoms that may occur when initiating Avonex therapy at a dose of 30 micrograms, Avonex may be started at a dose of 7.5 micrograms and the dose may be increased by 7.5 micrograms each week for the next three weeks until the recommended dose of 30 micrograms is achieved (see Table 1). An AVOSTARTGRIP™ kit containing 3 titration devices can be used for titration and is to be used only with Avonex Prefilled Syringes.

Table 1: Schedule for Dose Titration

1 Dosed once a week, intramuscularly

Avonex Dose1 Recommended Dose
Week 1 7.5 micrograms 1/4 dose
Week 2 15 micrograms 1/2 dose
Week 3 22.5 micrograms 3/4 dose
Week 4+ 30 micrograms full dose

Important Administration Instructions (All Dosage Forms)

All Avonex dosage forms are single-use (injection of reconstituted solution, prefilled syringe, and prefilled autoinjector). See Patient's Instructions for Use for complete administration instructions.

The first Avonex injection should be performed under the supervision of an appropriately qualified health care professional. If patients or caregivers are to administer Avonex, train them in the proper intramuscular injection technique and assess their ability to inject intramuscularly to ensure the proper administration of Avonex.

Advise patients and caregivers to:

  • Rotate sites for intramuscular injections with each injection to minimize the likelihood of injection site reactions
  • NOT inject into an area of the body where the skin is irritated, reddened, bruised, infected or scarred in any way
  • Check the injection site after 2 hours for redness, swelling, or tenderness
  • Contact their healthcare provider if they have a skin reaction and it does not clear up in a few days

A 25 gauge, 1” needle for intramuscular injection with Avonex prefilled syringe or injection of reconstituted solution may be substituted for the 23 gauge, 1 ¼” needle by the healthcare provider, if deemed appropriate. A 25 gauge, 5/8” needle specific to the prefilled autoinjector is supplied with the Avonex PEN® Administration Dose Pack. DO NOT use any other needle with the autoinjector.

Use safe disposal procedures for needles and syringes. Do not re-use needles, syringes, prefilled syringes, or autoinjectors. Following the administration of each titrated dose, discard any remaining product.

Premedication for Flu-like Symptoms

Concurrent use of analgesics and/or antipyretics on treatment days may help ameliorate flu-like symptoms associated with Avonex use.

Dosage Forms and Strengths

  • For injection: 30 micrograms lyophilized powder in a single-use vial
  • Injection: 30 micrograms per 0.5 mL solution in a single-use prefilled syringe
  • Injection: 30 micrograms per 0.5 mL solution in a single-use prefilled autoinjector

Contraindications

Avonex is contraindicated in patients with a history of hypersensitivity to natural or recombinant interferon beta, or any other component of the formulation [see Warnings and Precautions (5.3)].

The lyophilized vial formulation of Avonex is contraindicated in patients with a history of hypersensitivity to albumin (human).

Warnings and Precautions

Depression, Suicide, and Psychotic Disorders

Patients treated with Avonex and their caregivers should be advised to report immediately any symptoms of depression, suicidal ideation, and/or psychosis to their prescribing physicians. If a patient develops depression or other severe psychiatric symptoms, cessation of Avonex therapy should be considered.

Depression and suicide have been reported to occur with increased frequency in patients receiving Avonex. In Study 1, the incidence of depression was similar in placebo-treated and in Avonex-treated patients, but suicidal tendency was seen more frequently in Avonex-treated patients (4% in Avonex group vs. 1% in placebo group). In Study 2, there was a greater incidence of depression in Avonex-treated patients than in placebo-treated patients (20% in Avonex group vs. 13% in placebo group) [see Clinical Studies (14)].

Additionally, there have been postmarketing reports of depression, suicidal ideation, and/or development of new or worsening of other pre-existing psychiatric disorders, including psychosis. For some of these patients, symptoms of depression improved upon cessation of Avonex.

Hepatic Injury

Severe hepatic injury, including cases of hepatic failure, has been reported rarely in patients taking Avonex. Asymptomatic elevation of hepatic transaminases has also been reported, and in some patients has recurred upon rechallenge with Avonex. In some cases, these events have occurred in the presence of other drugs that have been associated with hepatic injury. The potential risk of Avonex used in combination with known hepatotoxic drugs or other products (e.g., alcohol) should be considered prior to starting Avonex, or before starting hepatotoxic drugs. Patients should be monitored for signs of hepatic injury [see Warnings and Precautions (5.8)].

Anaphylaxis and Other Allergic-Reactions

Anaphylaxis has been reported as a rare complication of Avonex use. Other allergic reactions have included dyspnea, orolingual edema, skin rash and urticaria. Discontinue Avonex if anaphylaxis or other allergic reactions occur.

Congestive Heart Failure

Patients with pre-existing congestive heart failure should be monitored for worsening of their cardiac condition during initiation of and continued treatment with Avonex. While beta interferons do not have any known direct cardiac toxicity, during the postmarketing period cases of congestive heart failure, cardiomyopathy, and cardiomyopathy with congestive heart failure have been reported in patients without known predisposition to these events, and without other etiologies being established. In some cases, these events have been temporally related to the administration of Avonex. In some of these instances recurrence upon rechallenge was observed.

Decreased Peripheral Blood Counts

Decreased peripheral blood counts in all cell lines, including rare pancytopenia and thrombocytopenia, have been reported from postmarketing experience in Avonex-treated patients [see Adverse Reactions (6.2)]. In some cases, platelet counts were below 10,000/microliter. Some cases recurred with rechallenge [see Adverse Reactions (6.2)]. Patients should be monitored for symptoms or signs of decreased blood counts.

Seizures

Seizures have been temporally associated with the use of beta interferons in clinical trials and postmarketing safety surveillance. In the two placebo-controlled studies in multiple sclerosis (Studies 1 and 2), 4 patients receiving Avonex experienced seizures, while no seizures occurred in the placebo group [see Clinical Studies (14)]. Three of these 4 patients had no prior history of seizure [see Adverse Reactions (6.1)]. It is not known whether these events were related to the effects of multiple sclerosis alone, to Avonex, or to a combination of both.

Autoimmune Disorders

Postmarketing reports of autoimmune disorders of multiple target organs in Avonex-treated patients included idiopathic thrombocytopenia, hyper- and hypothyroidism, and rare cases of autoimmune hepatitis. If Avonex-treated patients develop a new autoimmune disorder, consider stopping the therapy.

Laboratory Tests

In addition to those laboratory tests normally required for monitoring patients with multiple sclerosis, complete blood and differential white blood cell counts, platelet counts, and blood chemistries, including liver function tests, are recommended during Avonex therapy [see Warnings and Precautions (5.2, 5.5, 5.7)]. Patients with myelosuppression may require more intensive monitoring of complete blood cell counts, with differential and platelet counts. Thyroid function should be monitored periodically. If patients have or develop symptoms of thyroid dysfunction (hypo- or hyperthyroidism), thyroid function tests should be performed according to standard medical practice.

Adverse Reactions

The following serious adverse reactions are discussed in more detail in other sections of labeling:

  • Depression, Suicide, and Psychotic Disorders [see Warnings and Precautions (5.1)]
  • Hepatic Injury [see Warnings and Precautions (5.2)]
  • Anaphylaxis and Other Allergic-Reactions [see Warnings and Precautions (5.3)]
  • Congestive Heart Failure [see Warnings and Precautions (5.4)]
  • Decreased Peripheral Blood Counts [see Warnings and Precautions (5.5)]
  • Seizures [see Warnings and Precautions (5.6)]
  • Autoimmune Disorders [see Warnings and Precautions (5.7)]
  • Laboratory Tests [see Warnings and Precautions (5.8)]

Clinical Trials Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of Avonex cannot be directly compared to rates in clinical trials of other drugs and may not reflect the rates observed in practice.

Among 351 patients with relapsing forms of MS treated with Avonex 30 micrograms (including 319 patients treated for 6 months and 288 patients treated for greater than one year) the most commonly reported adverse reactions (at least 5% more frequent on Avonex than on placebo) were flu-like symptoms. Symptoms can include chills, fever, myalgia and asthenia occurring within hours to days following an injection. Most people who take Avonex have flu-like symptoms early during the course of therapy. Usually, these symptoms last for a day after the injection. For many people, these symptoms lessen or go away over time. The most frequently reported adverse reactions resulting in clinical intervention (for example, discontinuation of Avonex or the need for concomitant medication to treat an adverse reaction symptom) were flu-like symptoms and depression.

Table 2 enumerates adverse reactions that occurred with Avonex-treated patients at an incidence of at least 2% more than that observed in the placebo-treated patients in the pooled placebo-controlled studies in patients with relapsing forms of MS [see Clinical Studies (14)].

Immunogenicity

Anaphylaxis and other allergic reactions have occurred in Avonex-treated patients [see Warnings and Precautions (5.3)]. As with all therapeutic proteins, there is a potential for immunogenicity. In studies assessing immunogenicity in multiple sclerosis patients administered Avonex for at least 1 year, 5% (21 of 390 patients) showed the presence of neutralizing antibodies at one or more times.

These data reflect the percentage of patients whose test results were considered positive for antibodies to Avonex using a two-tiered assay (ELISA binding assay followed by an antiviral cytopathic effect assay), and are highly dependent on the sensitivity and specificity of the assay. Additionally, the observed incidence of neutralizing activity in an assay may be influenced by several factors including sample handling, timing of sample collection, concomitant medications, and underlying disease. For these reasons, comparison of the incidence of antibodies to Avonex with the incidence of antibodies to other products may be misleading.

Postmarketing Experience

The following additional adverse reactions have been identified during post-approval use of Avonex. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.

  • Menorrhagia and metrorrhagia
  • Rash (including vesicular rash)
  • Rare cases of injection site abscess or cellulitis requiring surgical intervention

USE IN SPECIFIC POPULATIONS

Pregnancy

Pregnancy Category C: There are no adequate and well-controlled studies in pregnant women. Avonex should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.

In pregnant monkeys given interferon beta at 100 times the recommended weekly human dose (based upon a body surface area [mg/m2] comparison), no teratogenic or other adverse effects on fetal development were observed. Abortifacient activity was evident following 3 to 5 doses at this level. No abortifacient effects were observed in monkeys treated at 2 times the recommended weekly human dose (based upon mg/m2).

Nursing Mothers

It is not known whether Avonex is excreted in human milk.

Pediatric Use

Safety and effectiveness in pediatric patients have not been established.

Geriatric Use

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

Avonex Description

Avonex is a 166 amino acid glycoprotein with a molecular weight of approximately 22,500 daltons. It is produced by recombinant DNA technology using genetically engineered Chinese Hamster Ovary cells into which the human interferon beta gene has been introduced. The amino acid sequence of Avonex is identical to that of natural human interferon beta.

Using the World Health Organization (WHO) International Standard for Interferon, Avonex has a specific activity of approximately 200 million international units of antiviral activity per mg of interferon beta-1a determined specifically by an in vitro cytopathic effect bioassay using lung carcinoma cells (A549) and Encephalomyocarditis virus (ECM). Avonex 30 micrograms contains approximately 6 million international units of antiviral activity using this method. The activity against other standards is not known. Comparison of the activity of Avonex with other interferon betas is not appropriate, because of differences in the reference standards and assays used to measure activity.

Avonex Lyophilized Powder Vial

A vial of Avonex is a sterile, white to off-white lyophilized powder for intramuscular injection after reconstitution with supplied diluent (Sterile Water for Injection, USP).

Avonex - Clinical Pharmacology

Mechanism of Action

The mechanism of action by which Avonex exerts its effects in patients with multiple sclerosis is unknown.

Pharmacodynamics

Interferons (IFNs) are a family of naturally occurring proteins, produced by eukaryotic cells in response to viral infection and other biologic agents. Three major types of interferons have been defined: type I (IFN-alpha, beta, epsilon, kappa and omega), type II (IFN–gamma) and type III (IFN-lambda). Interferon-beta is a member of the type I subset of interferons.  The type I interferons have considerably overlapping but also distinct biologic activities. The bioactivities of all IFNs, including IFN-beta, are induced via their binding to specific receptors on the membranes of human cells. Differences in the bioactivites induced by the three major subtypes of IFNs likely reflect differences in the signal transduction pathways induced by signaling through their cognate receptors.

Interferon beta exerts its biological effects by binding to specific receptors on the surface of human cells.  This binding initiates a complex cascade of intracellular events that leads to the expression of numerous interferon-induced gene products and markers.  These include 2', 5'-oligoadenylate synthetase, β2-microglobulin, and neopterin.  These products have been measured in the serum and cellular fractions of blood collected from patients treated with Avonex.

Clinical studies conducted in multiple sclerosis patients showed that interleukin 10 (IL-10) levels in cerebrospinal fluid were increased in patients treated with Avonex compared to placebo.  Serum IL-10 levels maximally were increased by 48 hours after intramuscular injection of Avonex and remained elevated for 1 week.  However, no relationship has been established between absolute levels of IL-10 and clinical outcome in multiple sclerosis.

Pharmacokinetics

Pharmacokinetics of Avonex in multiple sclerosis patients have not been evaluated. The pharmacokinetic and pharmacodynamic profiles of Avonex in healthy subjects following doses of 30 micrograms through 75 micrograms have been investigated. Serum levels of Avonex as measured by antiviral activity are slightly above detectable limits following a 30 microgram intramuscular dose, and increase with higher doses.

After an intramuscular dose, serum levels of Avonex generally peak at 15 hours post-dose (range: 6-36 hours) and then decline at a rate consistent with a 19 (range: 8-54) hour elimination half-life.

Subcutaneous administration of Avonex should not be substituted for intramuscular administration as there is no data establishing that subcutaneous and intramuscular administration of Avonex result in equivalent pharmacokinetic and pharmacodynamic parameters.

Biological response markers (e.g., neopterin and β2-microglobulin) are induced by Avonex following parenteral doses of 15 micrograms through 75 micrograms in healthy subjects and treated patients. Biological response marker levels increase within 12 hours of dosing and remain elevated for at least 4 days. Peak biological response marker levels are typically observed 48 hours after dosing. The relationship of serum Avonex levels or levels of these induced biological response markers to the mechanisms by which Avonex exerts its effects in multiple sclerosis is unknown.

Nonclinical Toxicology

Carcinogenesis, Mutagenesis, and Impairment of Fertility

Carcinogenesis: The carcinogenic potential of Avonex has not been tested in animals.

Mutagenesis: Interferon beta was not mutagenic when tested in an in vitro bacterial reverse mutation (Ames) test or in an in vitro cytogenetic assay in human lymphocytes.

Impairment of Fertility: In monkeys administered interferon beta by subcutaneous injection (8 to 15 doses of 1.25 mcg/kg or 50 mcg/kg) over the course of one menstrual cycle, menstrual irregularities, anovulation, and decreased serum progesterone levels were observed at the higher dose. These effects were reversible after discontinuation of drug. The no-effect dose (1.25 mcg/kg) is approximately 2 times the recommended weekly dose in humans (30 mcg) on a mg/m2 basis.

Clinical Studies

The clinical effects of Avonex in patients with relapsing forms of multiple sclerosis (MS) were studied in two randomized, multicenter, double-blind, placebo-controlled studies in patients with MS (Studies 1 and 2). Safety and efficacy of treatment with Avonex beyond 3 years is not known.

In Study 1, 301 patients received either 30 micrograms of Avonex (n=158) or placebo (n=143) by intramuscular injection once weekly. Patients received injections for up to 2 years, and continued to be followed until study completion. Two hundred eighty-two patients completed 1 year on study, and 172 patients completed 2 years on study. There were 144 patients treated with Avonex for more than 1 year, 115 patients for more than 18 months and 82 patients for 2 years.

All patients had a definite diagnosis of multiple sclerosis of at least 1 year duration and had at least 2 exacerbations in the 3 years prior to study entry (or 1 per year if the duration of disease was less than 3 years). At entry, study participants were without exacerbation during the prior 2 months and had Kurtzke Expanded Disability Status Scale (EDSS3) scores ranging from 1.0 to 3.5. The EDSS is a scale that quantifies disability in patients with MS and ranges from 0 (normal neurologic exam) to 10 (death due to MS). Patients with chronic progressive multiple sclerosis were excluded from this study.

Disability

The primary outcome assessment was time to progression in disability, measured as an increase in the EDSS score of at least 1 point that was sustained for at least 6 months. An increase in EDSS score reflects accumulation of disability. This endpoint was used to help distinguish permanent increase in disability from a transient increase due to an exacerbation.

As shown in Figure 1, the time to onset of sustained progression in disability was significantly longer in Avonex-treated patients than in placebo-treated patients in Study 1 (p = 0.02). The percentage of patients progressing by the end of 2 years was 35% for placebo-treated patients and 22% for Avonex-treated patients. This represents a 37% relative reduction in the risk of accumulating disability in the Avonex-treated group compared to the placebo-treated group.

1 Kaplan-Meier Methodology; Disability progression was defined as at least a 1 point increase in EDSS score sustained for at least 6 months.

The distribution of confirmed EDSS change from study entry (baseline) to the end of the study is shown in Figure 2. There was a statistically significant difference between the Avonex and placebo groups in confirmed change for patients with at least 2 scheduled visits (p = 0.006).

Exacerbations

The rate and frequency of MS exacerbations were secondary outcomes. For all patients included in the study, irrespective of time on study, the annual exacerbation rate was 0.67 per year in the Avonex-treated group and 0.82 per year in the placebo-treated group (p = 0.04).

Avonex treatment significantly decreased the frequency of exacerbations in the subset of patients who were enrolled in the study for at least 2 years (87 placebo-treated patients and 85 Avonex-treated patients; p = 0.03; see Table 3).

MRI Results

Gadolinium (Gd)-enhanced and T2-weighted magnetic resonance imaging (MRI) scans of the brain were obtained in most patients at baseline and at the end of 1 and 2 years of treatment. Secondary outcomes included Gd-enhanced lesion number and volume, and T2-weighted lesion volume. Gd-enhancing lesions seen on brain MRI scans represent areas of breakdown of the blood brain barrier thought to be secondary to inflammation. Avonex-treated patients demonstrated significantly lower Gd-enhanced lesion number after 1 and 2 years of treatment than placebo-treated patients (p ≤ 0.05; see Table 3). The volume of Gd-enhanced lesions showed similar treatment effects in the Avonex and placebo groups (p ≤ 0.03). Percentage change in T2-weighted lesion volume from study entry to Year 1 was significantly lower in Avonex-treated than placebo-treated patients (p = 0.02). A significant difference in T2-weighted lesion volume change was not seen between study entry and Year 2 in the Avonex and placebo groups.

The exact relationship between MRI findings and the clinical status of MS patients is unknown. The prognostic significance of MRI findings in these studies has not been evaluated.

In Study 2, 383 patients who had recently experienced an isolated demyelinating event involving the optic nerve, spinal cord, or brainstem/cerebellum, and who had lesions typical of multiple sclerosis on brain MRI, received either 30 micrograms of Avonex (n = 193) or placebo (n = 190) by intramuscular injection once weekly. Patients were enrolled into the study over a two-year period and followed for up to three years or until they developed a second clinical exacerbation in an anatomically distinct region of the central nervous system.

Exacerbations

In Study 2, the primary outcome measure was time to development of a second exacerbation in an anatomically distinct region of the central nervous system. Time to development of a second exacerbation was significantly delayed in Avonex-treated compared to placebo-treated patients (p = 0.002). The Kaplan-Meier estimates of the percentage of patients developing an exacerbation within 24 months were 39% in the placebo group and 21% in the Avonex group (see Figure 3). The relative rate of developing a second exacerbation in the Avonex group was 0.56 of the rate in the placebo group (95% confidence interval 0.38 to 0.81).

What is Avonex?

Avonex is a form of a protein called beta interferon that occurs naturally in the body. Avonex is a prescription medicine used to treat adults with relapsing forms of multiple sclerosis (MS). This includes people who have had their first symptoms of multiple sclerosis and have an MRI consistent with multiple sclerosis.

Avonex will not cure your MS but may decrease the number of flare-ups of the disease and slow the occurrence of some of the physical disability that is common in people with MS. MS is a life-long disease that affects your nervous system by destroying the protective covering (myelin) that surrounds your nerve fibers.

The way Avonex works in MS is not known.

It is not known if Avonex is safe and effective in children.

Who should not use Avonex?

Do not take Avonex if you:

  • are allergic to interferon beta, albumin (human), or any of the ingredients in Avonex. See the end of this Medication Guide for a complete list of ingredients in Avonex.

What should I tell my healthcare provider before using Avonex?

Before taking Avonex, tell your healthcare provider if you:

  • are being treated for a mental illness or had treatment in the past for any mental illness, including depression and suicidal behavior
  • have or had bleeding problems or blood clots
  • have or had low blood cell counts
  • have or had liver problems
  • have or had seizures (epilepsy)
  • have or had heart problems
  • have or had thyroid problems
  • have or had any kind of autoimmune disease (where the body's immune system attacks the body's own cells), such as psoriasis, systemic lupus erythematosus, or rheumatoid arthritis
  • drink alcohol
  • are pregnant or plan to become pregnant. It is not known if Avonex will harm your unborn baby. Tell your healthcare provider if you become pregnant during your treatment with Avonex.
  • are breastfeeding or plan to breastfeed. It is not known if Avonex passes into your breast milk. You and your healthcare provider should decide if you will use Avonex or breastfeed. You should not do both.

Tell your healthcare provider about all the medicines you take, including prescription and non-prescription medicines, vitamins, and herbal supplements.

How should I use Avonex?

  • Your healthcare provider should show you how to prepare and measure your dose of Avonex and how to inject your Avonex before you use Avonex for the first time.
  • Your healthcare provider or nurse should watch the first Avonex injection you give yourself.
  • Avonex is given once a week by injection into the muscle (intramuscular injection).
  • Inject Avonex exactly as your healthcare provider tells you.
  • Your healthcare provider will tell you how much Avonex to inject and how often to inject Avonex. Do not inject more than your healthcare provider tells you to.
  • If you miss a dose, you should take your next dose as soon as you remember. You should continue your regular schedule the following week. Do not take Avonex 2 days in a row.
  • Do not change your dose unless your healthcare provider tells you to.
  • Change (rotate) your injection site you choose with each injection. This will help decrease the chance that you will have an injection site reaction.
  • Do not inject into an area of the body where the skin is irritated, reddened, bruised, infected or scarred in any way.
  • Avonex comes as a:
    • Vial with freeze-dried (lyophilized) powder
    • Prefilled syringe (can be used with the AVOSTARTGRIP™ titration kit)
    • Single-Use Prefilled Autoinjector Pen (Avonex PEN®)

Your healthcare provider will decide which one is best for you. See the Instructions for Use at the end of this Medication Guide for detailed instructions for preparing and injecting your dose of Avonex.

  • Always use a new, unopened Avonex vial, prefilled syringe, or single-use prefilled autoinjector pen for each intramuscular injection.

What are the possible side effects of Avonex?

Avonex can cause serious side effects including:

  • See “What is the most important information I should know about Avonex?
  • Heart problems, including heart failure. While Avonex is not known to have any direct effects on the heart, a few patients who did not have a history of heart problems developed heart muscle problems or congestive heart failure after taking Avonex. If you already have heart failure, Avonex may cause your heart failure to get worse. Call your healthcare provider right away if you have worsening symptoms of heart failure such as shortness of breath or swelling of your lower legs or feet while using Avonex.
    • Some people using Avonex may have other heart problems including:
      • low blood pressure
      • fast or abnormal heart beat
      • chest pain
      • heart attack or a heart muscle problem (cardiomyopathy)
  • Blood problems. Avonex can affect your bone marrow and cause low red and white blood cell, and platelet counts. In some people, these blood cell counts may fall to dangerously low levels. If your blood cell counts become very low, you can get infections and problems with bleeding and bruising.
  • Seizures. Some patients have had seizures while taking Avonex, including patients who have never had seizures before.
  • Infections. Some people who take Avonex may get an infection. Symptoms of an infection may include:
    • fever
    • chills
    • pain or burning with urination
    • urinating often
    • bloody diarrhea
    • coughing up mucus
  • Thyroid problems. Some people taking Avonex develop changes in their thyroid function. Symptoms of thyroid changes include:
    • problems concentrating
    • feeling cold or hot all the time
    • weight changes (gain or loss)
    • skin changes

Tell your healthcare provider right away if you have any of the symptoms listed above.

The most common side effects of Avonex include:

  • Flu-like symptoms. Most people who take Avonex have flu-like symptoms early during the course of therapy. Usually, these symptoms last for a day after the injection. You may be able to manage these flu-like symptoms by taking over-the-counter pain and fever reducers. For many people, these symptoms lessen or go away over time. Symptoms may include:
    • muscle aches
    • fever
    • tiredness
    • chills

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

Instructions for Use

Avonex PEN® (a-vuh-necks) (pen)

(interferon beta-1a)

injection for intramuscular use

single-use prefilled autoinjector pen

Read the Instructions for Use before you start using Avonex and each time you get a refill. There may be new information. This information does not take the place of talking to your healthcare provider about your medical condition or your treatment.

Your healthcare provider should show you or your caregiver how to prepare the dose of Avonex and how to inject your Avonex PEN the right way before Avonex PEN is used for the first time.  Your healthcare provider or nurse should watch you inject the dose of Avonex the first time Avonex PEN is used.

Preparing the Avonex PEN:

  • Find a well lit, clean, flat work surface like a table and collect all the supplies you will need to give yourself or receive an injection.
  • Take 1 Avonex PEN Administration Dose Pack out of the refrigerator about 30 minutes before you plan on injecting the Avonex dose to allow it to reach room temperature. Do not use external heat sources such as hot water to warm the Avonex PEN.
  • Check the expiration date printed on the Avonex PEN, Avonex PEN Administration Dose Pack carton, and the outer carton. Do not use the Avonex PEN past the expiration date.
  • Wash your hands with soap and water.

Supplies you will need to give the Avonex PEN injection:

  • 1 Avonex Administration Dose Pack that contains:
    • 1 Avonex PEN
    • a 25 gauge, 5/8 inch long sterile needle
    • 1 Avonex PEN cover
  • 1 alcohol wipe
  • 1 gauze pad
  • 1 adhesive bandage
  • a puncture resistant container for disposal of used Avonex PEN and needle

Identifying parts of the Avonex PEN (See Figure A).

Single-Use Administration Dose Pack Contents – Avonex PEN, Supplied Needle and Avonex PEN Cover

                                                                                                                                    (Figure A)

Preparing the Avonex PEN injection:

Step 1: Hold the Avonex PEN with the white tamper-evident cap (cap) pointing up (See Figure B).
  • Check that the cap is intact and has not been removed. If the cap has been removed or is not tightly attached, do not use it, throw it away and get a new Avonex PEN.



(Figure B)
Step 2: With your other hand, grasp the cap and bend it at a 90° angle until the cap snaps off (See Figure C).
  • After the cap comes off, you will see the glass tip of the syringe. Do not touch the glass tip of the syringe (See Figure D).


(Figure C)

(Figure D)
Step 3: Place the Avonex PEN down on a flat work surface.
Step 4: Pull off the sterile foil from the needle cover (See Figure E).
  • Only use the needle that comes with your Avonex PEN.


(Figure E)
Step 5: Hold the Avonex PEN with the glass syringe tip pointing up. Press the needle onto the Avonex PEN glass syringe tip (See Figure F).

(Figure F)
Step 6: Gently turn the needle clockwise until it is firmly attached (See Figure G).
  • If the needle is not firmly attached, it may leak, and you may not get your full dose of Avonex.

(Figure G)
  • Do not remove the plastic cover from the needle (See Figure H).


(Figure H)
Step 7: Hold the body of the Avonex PEN in 1 hand with the needle and needle cover pointing away from you and other people. Do not remove the plastic cover from the needle (See Figure I).

(Figure I)
Step 8: Using your other hand, hold onto the injector shield (grooved area) tightly and quickly pull up on the injector shield until the injector shield covers the needle all the way.
  • The plastic needle cover will “pop” off after the injector shield has been fully extended (See Figure J).


(Figure J)
  • When the injector shield is extended the right way, you will see a small blue rectangular area next to the oval medication display window (See Figure K).


(Figure K)
Step 9: Check the oval medication display window and make sure the Avonex is clear and colorless (See Figure L).
You might see air bubbles in the oval display window. This is normal and will not affect your dose.
  • Do not use Avonex PEN if the liquid is colored, cloudy, or contains any lumps or particles. Throw away the Avonex PEN and get a new one, then repeat steps 1 to 9.

(Figure L)

Giving the Avonex injection:

  • Your healthcare provider should show you or your caregiver how to prepare the dose of Avonex and how to inject your Avonex PEN the right way before Avonex PEN is used for the first time. Your healthcare provider or nurse should watch you inject the dose of Avonex the first time Avonex PEN is used.
  • Inject your Avonex PEN exactly as your healthcare provider has shown you.
  • Avonex PEN is injected into the muscle (intramuscularly).
  • Avonex PEN should be injected into the upper, outer thigh (See Figure M).
  • Change (rotate) injection sites for each dose. Do not use the same injection site for each injection.
  • Do not inject into an area of the body where the skin is irritated, reddened, bruised, infected or scarred in any way.
  • Do not push down on the injector shield and the blue activation button at the same time until you are ready to give your injection.

                                                                                                                                    Figure M

Step 10: Choose an injection site and wipe the skin with an alcohol wipe (See Figure N). Let the injection site dry before injecting the dose.
  • Do not touch this area again before giving the injection.



(Figure N)
Step 11: Place the Avonex PEN on the injection site (See Figure O).

(Figure O)
Step 12: Hold the body of the Avonex PEN at a 90º angle to the injection site, and make sure you can see the windows (See Figure P).

(Figure P)
Step 13: Keeping your fingers away from the blue activation button, firmly push the body of the Avonex PEN down against the thigh to release the safety lock (See Figure Q). Do not lift the Avonex PEN off of the injection site.
  • Check to make sure the safety lock has been released. You will know the safety lock is released when the small blue rectangular area above the oval medication display window is gone (See Figure R).


(Figure Q)


(Figure R)
Step 14: Continue to firmly maintain pressure and push down on the Avonex PEN against the injection site, then push down on the blue activation button with your thumb (See Figure S). Keep the Avonex PEN pushed down against the injection site and slowly count to 10.
  • You will hear a “click” when the injection starts. If you do not hear a “click”, your injection was not given the right way.
    • If this happens, make sure that the injector shield is extended, the safety lock is completely released, and that you are firmly maintaining pressure and pushing down against the injection site. Press the blue activation button with your thumb again. If you still do not hear a “click”, call Biogen Idec Inc. at 1-800-456-2255.

(Figure S)


Step 15: After you count to 10, pull the Avonex PEN straight out of the skin (See Figure T). Use the gauze pad to apply pressure to the injection site for a few seconds or rub gently in a circular motion.
  • If you see blood after you press the injection site for a few seconds, wipe it off with gauze and apply an adhesive bandage.

(Figure T)
Step 16: Check the circular display window on the Avonex PEN to make sure that it is yellow. This is to be sure that you have been given your full dose (See Figure U).
  • If you did not receive your full dose of Avonex, throw away the Avonex PEN and call your doctor. Do not re-use the Avonex PEN.



(Figure U)
STEP 17: Do not hold the Avonex PEN cover with your hands. Place the Avonex PEN cover on a flat work surface. Line up the exposed needle with the hole of the Avonex PEN cover, and insert directly into the opening (See Figure V).
(Figure V)
STEP 18: Firmly press the Avonex PEN down until you hear a “click” to seal the needle (See Figure W). You may need to hold both hands around the Avonex PEN body to snap the Avonex PEN cover into place.
(Figure W)

After the Avonex injection:

  • Throw away the used Avonex PENS and needles in a sharps container or some type of hard plastic or metal container with a screw cap such as a detergent bottle or coffee can. Check with your healthcare provider about the right way to throw away the container. There may be local or state laws about how to throw away used Avonex PENS and needles. Do not throw away used Avonex PENS and needles in household trash or recycling bins.
  • After 2 hours, check the injection site for redness, swelling or tenderness. If you have a skin reaction and it does not clear up in a few days, contact your healthcare provider.

Instructions for Use

AVOSTARTGRIP® Titration Kit

Use with Avonex® (interferon beta-1a) Prefilled Syringe Only

Read the Instructions for Use before you start using Avonex and each time you get a refill. There may be new information. This information does not take the place of talking to your healthcare provider about your medical condition or your treatment.

Preparing the Avonex Prefilled Syringe:

  • Find a well lit, clean, flat work surface like a table and collect all the supplies you will need to give yourself or receive an injection.
  • Take 1 Avonex Administration Dose Pack out of the refrigerator about 30 minutes before you plan on injecting the Avonex dose to allow it to reach room temperature. Do not use external heat sources such as hot water to warm the Avonex prefilled syringe.
  • Check the expiration date printed on the Avonex prefilled syringe, Avonex prefilled syringe Administration Dose Package carton, and the outer carton. Do not use the Avonex prefilled syringe past the expiration date.
  • Wash your hands with soap and water.

Supplies you will need for the Avonex injection:

  • 1 Avonex Administration Dose Pack that contains:
    • 1 Avonex prefilled syringe
    • 23 gauge, 1¼ inch long sterile needle
  • 1 alcohol wipe
  • 1 gauze pad
  • 1 adhesive bandage
  • a puncture resistant container for disposal of used syringes and needles

Identifying parts of the Avonex prefilled syringe (See Figure A):

Preparing the Avonex injection:

Step 1: Hold the Avonex prefilled syringe with the cap pointing down and with the 0.5 mL mark at eye level (See Figure A).
  • Check the syringe:
    • The syringe should not have any cracks or damage.
    • Check that the cap is intact and has not been removed.
    • The amount of liquid in the syringe should be at or very close to the 0.5 mL mark.
    • Avonex should look clear, colorless, and should not have any particles in it.
  • Do not use the Avonex prefilled syringe if:
    • the syringe is cracked or damaged
    • the solution is cloudy, colored, or has lumps or particles in it
    • the cap has been removed or is not tightly attached or
    • there is not enough liquid in the syringe
Do not use that syringe. Get a new syringe. Contact MS ActiveSource at 1-800-456-2255.


(Figure A)
Step 2: With 1 hand, hold the Avonex prefilled syringe right under the cap and with the cap pointing up (See Figure B).
  • Make sure you are holding the Avonex prefilled syringe by the ridged part, directly under the cap.

(Figure B)
Step 3: With the other hand, grasp the cap and bend it at a 90º angle until the cap snaps off (See Figure C and Figure D).


(Figure C)

(Figure D)
Step 4: Open the sterile needle package and take out the covered needle. Hold the Avonex prefilled syringe with the glass syringe tip pointing up. Press the needle on the Avonex prefilled syringe glass tip (See Figure E).


(Figure E)
Step 5: Gently turn the needle forward (clockwise) until it is tight and firmly attached (See Figure F).
  • If the needle is not firmly attached, it may leak and you may not get your full dose of Avonex.
  • Do not remove the plastic cover from the needle.

(Figure F)

Using the Avonex prefilled syringe with the AVOSTARTGRIP titration kit:

  • Your Avonex dose may be titrated over 3 weeks by using Avonex prefilled syringe with the AVOSTARTGRIP titration kit. The AVOSTARTGRIP is used for giving the week 1, 2, and 3 (¼, ½, ¾) injections.
    • Week 1: ¼ dose (white device)
    • Week 2: ½ dose (yellow device)
    • Week 3: ¾ dose (purple device)
    • Week 4: a full dose
  • The 3 AVOSTARTGRIP devices are for single-use only with the Avonex prefilled syringe. Do not re-use the Avonex prefilled syringe and AVOSTARTGRIP devices.
  • You must prepare the Avonex prefilled syringe and needle before you put it into the AVOSTARTGRIP device. Follow steps 1 to 5 above to prepare the Avonex prefilled syringe.

Identifying the parts of AVOSTARTGRIP titration kit (See Figure G):

                                                                                                                                    (Figure G)

  • AVOSTARTGRIP has a “collar” on top of the device that will stop the syringe from injecting a full dose (See Figure H). The “collar” makes sure that you do not get the full dose of Avonex.

                                                                                                                                    (Figure H)

Attaching the AVOSTARTGRIP device:

Step 6: Choose the right AVOSTARTGRIP titration device for your weekly dose.
  • Week 1 Injection: Choose the white device to give ¼ dose (See Figure I).





  • Week 2 Injection: Choose the yellow device to give ½ dose (See Figure J).






  • Week 3 Injection: Choose the purple device to give ¾ dose (See Figure K).

(Figure I)

(Figure J)

(Figure K)
Step 7: Put the right AVOSTARTGRIP device on a flat surface with the door open (See Figure L).

(Figure L)
Step 8: Line up the Avonex prefilled syringe over the AVOSTARTGRIP device with the plunger pointing to the left and the needle pointing to the right (See Figure M).

(Figure M)
Step 9: Push the Avonex prefilled syringe down into the AVOSTARTGRIP device until both ends “snap” into place (See Figure N).

(Figure N)
Step 10: Using two fingers, push the door down until it closes over the Avonex prefilled syringe (See Figure O).
  • You will hear a “snap” when the door is closed the right way. Do not open door after it is closed.

(Figure O)
Step 11: Check to make sure that the Avonex prefilled syringe is in the AVOSTARTGRIP device the right way and that the door is tightly closed.

Giving the Avonex injection:

  • Your healthcare provider should show you or a caregiver how to prepare and inject the dose of Avonex before Avonex prefilled syringe is used for the first time. Your healthcare provider or nurse should watch you inject the dose of Avonex the first time Avonex prefilled syringe is used.
  • Inject your Avonex exactly as your healthcare provider has shown you.
  • Avonex is injected into the muscle (intramuscularly).
  • Avonex should be injected into the thigh or upper arm (See Figures P and Q).
  • Change (rotate) your injection sites for each dose. Do not use the same injection site for each injection.
  • Do not inject into an area of the body where the skin is irritated, reddened, bruised, infected or scarred in any way.
Step 12: Choose an injection site and wipe the skin with an alcohol wipe (See Figures P and Q). Let the injection site dry before injecting the dose.
  • Do not touch this area again before giving the injection.

       
(Figure P)             (Figure Q)

Step 13: Pull the protective cover straight off the needle (See Figure R). Do not twist the cover off.


(Figure R)
Step 14: With 1 hand, stretch the skin out around the injection site. With the other hand, hold the syringe like a pencil. Use a quick dart-like motion and insert the needle at a 90º angle, through the skin and into the muscle (See Figure S). Once the needle is in, let go of the skin.
(Figure S)
Step 15: Make sure that you push the plunger all the way down until it touches the collar (See Figure T).
(Figure T)
Step 16: Pull the needle out of the skin (See Figure U). Press down on the injection site with the gauze pad for a few seconds or rub gently in a circular motion.
  • If you see blood after you press the injection site for a few seconds, wipe it off with gauze and apply an adhesive bandage.

(Figure U)

After the Avonex injection:

Do not recap the needle. Recapping the needle can lead to a needle stick injury.

  • Throw away the used Avonex prefilled syringes, AVOSTARTGRIP devices, and needles in a sharps container or some type of hard plastic or metal container with a screw cap such as a detergent bottle or coffee can. Check with your healthcare provider about the right way to throw away the container. There may be local or state laws about how to throw away used Avonex prefilled syringes, AVOSTARTGRIP devices, and needles. Do not throw away used Avonex prefilled syringes, AVOSTARTGRIP devices, and needles in household trash or recycling bins.
  • After 2 hours, check the injection site for redness, swelling or tenderness. If you have a skin reaction and it does not clear up in a few days, contact your healthcare provider.

General information about the safe and effective use of Avonex

  • Always use a new Avonex prefilled syringe, AVOSTARTGRIP device, and needle for each injection. Do not re-use your Avonex prefilled syringe, AVOSTARTGRIP device, or needles.
  • Do not share your Avonex prefilled syringe, AVOSTARTGRIP device, or needles.
  • Keep the Avonex prefilled syringe, AVOSTARTGRIP device, and needles out of the reach of children.
  • You can use the table below to keep track of your weekly injections.

Instructions for Use

Avonex® (a-vuh-necks)

(interferon beta-1a)

lyophilized powder for intramuscular injection

single-use vial

Read the Instructions for Use before you start using Avonex and each time you get a refill. There may be new information. This information does not take the place of talking with your healthcare provider about your medical condition or your treatment.

Supplies you will need for the Avonex injection (See Figure A):

  • 1 Avonex Administration Dose Pack that contains:
    • 1 vial of Avonex (white to off-white powder or cake)
    • 10 mL diluent vial (Sterile Water for Injection, USP)
    • a 3 mL syringe
    • 1 MICRO PIN® (vial access pin)
    • 23 gauge, 1¼ inch long sterile needle
    • 2 alcohol wipes
    • 1 gauze pad
    • 1 adhesive bandage
  • a puncture resistant container for disposal of used syringes, needles, and MICRO PIN

Preparing the Avonex dose:

  • Find a well-lit, clean, flat work surface like a table and collect all the supplies you will need to give yourself or receive an injection.
  • Take 1 Avonex Administration Dose Pack out of the refrigerator about 30 minutes before you plan on injecting the Avonex dose to allow it to reach room temperature.
  • Before you start to prepare the injection, check the expiration date on the Avonex and diluent vials. Do not use Avonex or diluent past the expiration date printed on the label.
  • Wash your hands with soap and water.

                                                                                                                                    (Figure A)

Preparing the Avonex dose:

Step 1: Pull off the cap from the vial of Avonex and the vial of diluent (See Figure B).


(Figure B)
Step 2: Wipe the rubber stopper on each vial with an alcohol wipe (See Figure C).

(Figure C)
Step 3: Open the sterile package and take out the MICRO PIN. Hold the syringe with the tip pointing up. Push the MICRO PIN down onto the top of the syringe. Turn the MICRO PIN counterclockwise until it is tight and firmly attached (See Figure D).
  • Do not over-tighten the MICRO PIN, it can make it hard to remove.



(Figure D)
Step 4: Pull straight up on the MICRO PIN cover to remove it, and save the cover for later (See Figure E). Do not twist the MICRO PIN cover when you are removing it.


(Figure E)
Step 5: Pull down the syringe plunger until the rubber tip reaches the 1.1 mL mark (See Figure F).

(Figure F)
Step 6: Push the MICRO PIN down through the center of the rubber stopper of the diluent vial (See Figure G).


(Figure G)
Step 7: Push the plunger all the way in. This puts air into the diluent vial (See Figure H).

(Figure H)
Step 8: Keep the MICRO PIN in the vial. Turn the diluent vial and syringe upside down and slowly pull the plunger down until the rubber tip reaches the 1.1 mL mark on the syringe (See Figure I).
  • If there are air bubbles, tap the syringe gently a few times to let any air bubbles rise to the top (See Figure J). If you still see air bubbles, slowly push the plunger up until the bubbles come out through the needle. Check to make sure there is still 1.1 mL of diluent in the syringe.


(Figure I)



(Figure J)
Step 9: Slowly pull the MICRO PIN out of the diluent vial's rubber stopper (See Figure K).

(Figure K)
Step 10: Push the MICRO PIN through the center of the rubber stopper of the Avonex vial (See Figure L).
  • If the rubber stopper of the Avonex vial falls into the vial, do not use the Avonex. Throw away the Avonex vial and get a new one, then repeat steps 1 to 10.



(Figure L)
Step 11: Slowly push the plunger all the way in. This puts the diluent into the vial of Avonex. Do not remove the syringe (See Figure M).
  • Do not aim the stream of diluent directly on the Avonex powder or push the plunger down too fast. If you aim the stream of diluent directly on the Avonex powder or push the plunger down too fast, the Avonex may foam and make it hard to withdraw the Avonex into the syringe.


(Figure M)
Step 12: Gently swirl the Avonex vial until the powder in the vial is dissolved (See Figure N). Do not shake the Avonex vial.
  • Check the Avonex vial to make sure that all of the Avonex is dissolved.
  • Avonex should look clear to slightly yellow in color after mixing and should not have any particles in it. Do not use Avonex if it looks cloudy, is colored any color other than slightly yellow, or has any lumps or particles in it.

Do not use that vial. Get a new vial. Contact MS ACTIVESOURCE at 1-800-456-2255.


(Figure N)
Step 13: Turn the Avonex vial and syringe upside down and slowly pull the plunger down until the rubber tip reaches the 1 mL mark on the syringe (See Figure O).
  • If there are large bubbles in the syringe, slowly push the plunger all the way in to push the Avonex solution back into the vial, then repeat Step 13.
  • If there are small air bubbles, tap the syringe gently a few times to let any air bubbles rise to the top (See Figure P). If you still see air bubbles, slowly push the plunger up until the bubbles come out through the needle.



(Figure O)

(Figure P)
Step 14: Pull the MICRO PIN and syringe out of the Avonex vial's rubber stopper (See Figure Q).



(Figure Q)
Step 15: Put the cover back on the MICRO PIN (See Figure R) and turn it clockwise to remove the MICRO PIN from the syringe (See Figure S).
(Figure R)


(Figure S)
Step 16: Open the sterile needle package and take out the covered needle. Hold the syringe with the tip pointing up. Push the needle onto the syringe and turn it forward (clockwise) until it is tight and firmly attached (See Figure T).
  • If the needle is not firmly attached, it may leak and you may not get your full dose of Avonex.
  • Do not remove the plastic cover from the needle.




(Figure T)

Giving the Avonex injection:

  • Your healthcare provider should show you or a caregiver how to prepare and inject the dose of Avonex before Avonex is used for the first time. Your healthcare provider or nurse should watch you inject the dose of Avonex the first time Avonex is used.
  • Inject your Avonex exactly as your healthcare provider has shown you.
  • Avonex is injected into the muscle (intramuscularly).
  • Avonex should be injected into the thigh or upper arm (See Figures U and V).
  • Change (rotate) your injection sites. Do not use the same site for each injection.
  • Do not inject into an area of the body where the skin is irritated, reddened, bruised, infected or scarred in any way.
Step 17: Choose an injection site and wipe the skin with an alcohol wipe (See Figures U and V). Let the injection site dry before injecting the dose.
  • Do not touch this area again before giving the injection.

       
(Figure U)             (Figure V)


Step 18: Pull the protective cover straight off the needle (See Figure W). Do not twist the cover off.

(Figure W)
Step 19: With 1 hand, stretch the skin out around the injection site. With the other hand, hold the syringe like a pencil. Use a quick dart-like motion and insert the needle at a 90 degree angle, through the skin and into the muscle (See Figure X). Once the needle is in, let go of the skin.


(Figure X)
Step 20: Slowly push the plunger in until the syringe is empty (See Figure Y).




(Figure Y)
Step 21: Pull the needle out of the skin (See Figure Z). Press down on the injection site with the gauze pad for a few seconds or rub gently in a circular motion.
  • If you see blood after you press the injection site for a few seconds, wipe it off with gauze and apply an adhesive bandage.


(Figure Z)

After the Avonex injection:

  • Do not recap the needle. Recapping the needle can lead to a needle stick injury.
  • Throw away empty Avonex and diluent vials, used syringes, needles, and MICRO PINS in a sharps container or some type of hard plastic or metal container with a screw cap such as a detergent bottle or coffee can. Check with your healthcare provider about the right way to throw away the container. There may be local or state laws about how to throw away the used syringes and needles. Do not throw away the used syringes and needles in household trash or recycling bins.
  • After 2 hours, check the injection site for redness, swelling or tenderness. If you have a skin reaction and it does not clear up in a few days, contact your healthcare provider.
