    2.2 Reconstitution of the Lyophilized Powder

    (a) Prior to reconstitution, verify that the vial containing lyophilized Betaseron is not cracked or damaged. Do not use cracked or damaged vials.

    (b) To reconstitute lyophilized Betaseron for injection, attach the prefilled syringe containing the diluent (Sodium Chloride, 0.54% Solution) to the Betaseron vial using the vial adapter.

    (c) Slowly inject 1.2 mL of diluent into the Betaseron vial.

    (d) Gently swirl the vial to dissolve the lyophilized powder completely; do not shake. Foaming may occur during reconstitution or if the vial is swirled or shaken too vigorously. If foaming occurs, allow the vial to sit undisturbed until the foam settles.

    (e) 1 mL of reconstituted Betaseron solution contains 0.25 mg of interferon beta-1b.

    (f) After reconstitution, if not used immediately, refrigerate the reconstituted Betaseron solution at 2 to 8°C (35 to 46°F) and use within three hours. Do not freeze.

    2.3 Important Administration Instructions

    (a) Perform the first Betaseron injection under the supervision of an appropriately qualified healthcare professional. If patients or caregivers are to administer Betaseron, train them in the proper subcutaneous injection technique and assess their ability to inject subcutaneously to ensure the proper administration of Betaseron.

    (b) Visually inspect the reconstituted Betaseron solution before use; discard if it contains particulate matter or is discolored.

    (c) Keeping the syringe and vial adapter in place, turn the assembly over so that the vial is on top. Withdraw the appropriate dose of Betaseron solution. Remove the vial from the vial adapter before injecting Betaseron.

    (d) Use safe disposal procedures for needles and syringes.

    (e) Do not re-use needles or syringes.

    (f) Advise patients and caregivers to rotate sites for subcutaneous injections to minimize the likelihood of severe injection site reactions, including necrosis or localized infection.

    2.4 Premedication for Flu-like Symptoms

    Concurrent use of analgesics and/or antipyretics on treatment days may help ameliorate flu-like symptoms associated with Betaseron use [see Warnings and Precautions (5.7)].

  • 5 WARNINGS AND PRECAUTIONS

    5.1 Hepatic Injury

    Severe hepatic injury including cases of hepatic failure, some of which have been due to autoimmune hepatitis, has been rarely reported in patients taking Betaseron. In some cases, these events have occurred in the presence of other drugs or comorbid medical conditions that have been associated with hepatic injury. Consider the potential risk of Betaseron used in combination with known hepatotoxic drugs or other products (e.g., alcohol) prior to Betaseron administration, or when adding new agents to the regimen of patients already on Betaseron. Monitor patients for signs and symptoms of hepatic injury. Consider discontinuing Betaseron if serum transaminase levels significantly increase, or if they are associated with clinical symptoms such as jaundice.

    Asymptomatic elevation of serum transaminases is common in patients treated with Betaseron. In controlled clinical trials, elevations of SGPT to greater than five times baseline value were reported in 12% of patients receiving Betaseron (compared to 4% on placebo), and increases of SGOT to greater than five times baseline value were reported in 4% of patients receiving Betaseron (compared to 1% on placebo), leading to dose-reduction or discontinuation of treatment in some patients [see Adverse Reactions (6.1)]. Monitor liver function tests [see Warnings and Precautions (5.9)].

    5.2 Anaphylaxis and Other Allergic-Reactions

    Anaphylaxis has been reported as a rare complication of Betaseron use. Other allergic reactions have included dyspnea, bronchospasm, tongue edema, skin rash and urticaria [see Adverse Reactions (6.1)]. Discontinue Betaseron if anaphylaxis occurs.

    5.3 Depression and Suicide

    Depression and suicide have been reported to occur with increased frequency in patients receiving interferon beta products, including Betaseron. Advise patients to report any symptom of depression and/or suicidal ideation to their healthcare provider. If a patient develops depression, discontinuation of Betaseron therapy should be considered.

    In randomized controlled clinical trials, there were three suicides and eight suicide attempts among the 1532 patients on Betaseron compared to one suicide and four suicide attempts among 965 patients on placebo.

    5.4 Congestive Heart Failure

    Monitor patients with pre-existing congestive heart failure (CHF) for worsening of their cardiac condition during initiation of and continued treatment with Betaseron. While beta interferons do not have any known direct-acting cardiac toxicity, cases of CHF, cardiomyopathy, and cardiomyopathy with CHF have been reported in patients without known predisposition to these events, and without other known etiologies being established. In some cases, these events have been temporally related to the administration of Betaseron. Recurrence upon rechallenge was observed in some patients. Consider discontinuation of Betaseron if worsening of CHF occurs with no other etiology.

    5.5 Injection Site Necrosis and Reactions

    Injection site necrosis (ISN) was reported in 4% of Betaseron-treated patients in controlled clinical trials (compared to 0% on placebo) [see Adverse Reactions (6.1)]. Typically, ISN occurs within the first four months of therapy, although postmarketing reports have been received of ISN occurring over one year after initiation of therapy. The necrotic lesions are typically three cm or less in diameter, but larger areas have been reported. Generally the necrosis has extended only to subcutaneous fat, but has extended to the fascia overlying muscle. In some lesions where biopsy results are available, vasculitis has been reported. For some lesions, debridement, and/or skin grafting have been required. In most cases healing was associated with scarring.

    Whether to discontinue therapy following a single site of necrosis is dependent on the extent of necrosis. For patients who continue therapy with Betaseron after injection site necrosis has occurred, avoid administration of Betaseron into the affected area until it is fully healed. If multiple lesions occur, discontinue therapy until healing occurs.

    Periodically evaluate patient understanding and use of aseptic self-injection techniques and procedures, particularly if injection site necrosis has occurred.

    In controlled clinical trials, injection site reactions occurred in 78% of patients receiving Betaseron with injection site necrosis in 4%. Injection site inflammation (42%), injection site pain (16%), injection site hypersensitivity (4%), injection site necrosis (4%), injection site mass (2%), injection site edema (2%) and nonspecific reactions were significantly associated with Betaseron treatment. The incidence of injection site reactions tended to decrease over time. Approximately 69% of patients experienced injection site reactions during the first three months of treatment, compared to approximately 40% at the end of the studies.

    5.6 Leukopenia

    In controlled clinical trials, leukopenia was reported in 18% of patients receiving Betaseron (compared to 6% on placebo), leading to a reduction of the dose of Betaseron in some patients [see Adverse Reactions (6.1)]. Monitoring of complete blood and differential white blood cell counts is recommended. Patients with myelosuppression may require more intensive monitoring of complete blood cell counts, with differential and platelet counts.

    5.7 Flu-Like Symptom Complex

    In controlled clinical trials, the rate of flu-like symptom complex for patients on Betaseron was 57% [see Adverse Reactions (6.1)]. The incidence decreased over time, with 10% of patients reporting flu-like symptom complex at the end of the studies. The median duration of flu-like symptom complex in Study 1 was 7.5 days [see Clinical Studies (14)]. Analgesics and/or antipyretics on treatment days may help ameliorate flu-like symptoms associated with Betaseron use.

    5.8 Seizures

    Seizures have been temporally associated with the use of beta interferons in clinical trials and postmarketing safety surveillance. It is not known whether these events were related to a primary seizure disorder, the effects of multiple sclerosis alone, the use of beta interferons, other potential precipitants of seizures (e.g., fever), or to some combination of these.

    5.9 Monitoring for Laboratory Abnormalities

    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 at regular intervals (one, three, and six months) following introduction of Betaseron therapy, and then periodically thereafter in the absence of clinical symptoms.

    6.1 Clinical Trials Experience

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

    Among 1407 patients with MS treated with Betaseron 0.25 mg every other day (including 1261 patients treated for greater than one year), the most commonly reported adverse reactions (at least 5% more frequent on Betaseron than on placebo) were injection site reaction, lymphopenia, flu-like symptoms, myalgia leukopenia, neutropenia, increased liver enzymes, headache, hypertonia, pain, rash, insomnia, abdominal pain, and asthenia. The most frequently reported adverse reactions resulting in clinical intervention (for example, discontinuation of Betaseron, adjustment in dosage, or the need for concomitant medication to treat an adverse reaction symptom) were depression, flu-like symptom complex, injection site reactions, leukopenia, increased liver enzymes, asthenia, hypertonia, and myasthenia.

    Table 2 enumerates adverse reactions and laboratory abnormalities that occurred among patients treated with 0.25 mg of Betaseron every other day by subcutaneous injection in the pooled placebo-controlled trials (Study 1-4) at an incidence that was at least 2% more than that observed in the placebo-treated patients [see Clinical Studies (14)].

    In addition to the Adverse Reactions listed in Table 2, the following adverse reactions occurred more frequently on Betaseron than on placebo, but with a difference smaller than 2%: alopecia, anxiety, arthralgia, constipation, diarrhea, dizziness, dyspepsia, dysmenorrhea, leg cramps, menorrhagia, myasthenia, nausea, nervousness, palpitations, peripheral vascular disorder, prostatic disorder, tachycardia, urinary frequency, vasodilatation, and weight increase.

    Laboratory Abnormalities

    In the four clinical trials (Studies 1, 2, 3, and 4), leukopenia was reported in 18% and 6% of patients in Betaseron- and placebo-treated groups, respectively. No patients were withdrawn or dose reduced for neutropenia in Study 1. Three percent (3%) of patients in Studies 2 and 3 experienced leukopenia and were dose-reduced. Other abnormalities included increase of SGPT to greater than five times baseline value (12%), and increase of SGOT to greater than five times baseline value (4%). In Study 1, two patients were dose reduced for increased hepatic enzymes; one continued on treatment and one was ultimately withdrawn. In Studies 2 and 3, 1.5% of Betaseron patients were dose-reduced or interrupted treatment for increased hepatic enzymes. In Study 4, 1.7% of patients were withdrawn from treatment due to increased hepatic enzymes, two of them after a dose reduction. In Studies 1-4, nine (0.6%) patients were withdrawn from treatment with Betaseron for any laboratory abnormality, including four (0.3%) patients following dose reduction.

    6.2 Immunogenicity

    As with all therapeutic proteins, there is a potential for immunogenicity. Serum samples were monitored for the development of antibodies to Betaseron during Study 1. In patients receiving 0.25 mg every other day 56/124 (45%) were found to have serum neutralizing activity at one or more of the time points tested. In Study 4, neutralizing activity was measured every 6 months and at end of study. At individual visits after start of therapy, activity was observed in 17% up to 25% of the Betaseron-treated patients. Such neutralizing activity was measured at least once in 75 (30%) out of 251 Betaseron patients who provided samples during treatment phase; of these, 17 (23%) converted to negative status later in the study. Based on all the available evidence, the relationship between antibody formation and clinical safety or efficacy is not known.

    These data reflect the percentage of patients whose test results were considered positive for antibodies to Betaseron using a biological neutralization assay that measures the ability of immune sera to inhibit the production of the interferon-inducible protein, MxA. Neutralization assays 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 Betaseron with the incidence of antibodies to other products may be misleading.

    Anaphylactic reactions have been reported with the use of Betaseron [see Warnings and Precautions (5.2)].

    6.3 Postmarketing Experience

    The following adverse reactions have been identified during postapproval use of Betaseron. 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.

    Blood and lymphatic system disorders: Anemia, Thrombocytopenia

    Endocrine disorders: Hypothyroidism, Hyperthyroidism, Thyroid dysfunction

    Metabolism and nutrition disorders: Triglycerideincreased, Anorexia, Weight decrease, Weight increase

  • 8 USE IN SPECIFIC POPULATIONS

    8.1 Pregnancy

    Pregnancy Category C: There are no adequate and well-controlled studies in pregnant women; however, spontaneous abortions while on treatment were reported in four patients participating in the Betaseron RRMS clinical trial. Betaseron should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.

    When Betaseron (doses ranging from 0.028 to 0.42 mg/kg/day) was administered to pregnant rhesus monkeys throughout the period of organogenesis (gestation days 20 to 70), a dose-related abortifacient effect was observed. The low-effect dose is approximately 3 times the recommended human dose of 0.25 mg on a body surface area (mg/m2) basis. A no-effect dose for embryo-fetal developmental toxicity in rhesus monkeys was not established.

    8.3 Nursing Mothers

    It is not known whether Betaseron is excreted in human milk. Because many drugs are excreted in human milk and because of the potential for serious adverse reactions in nursing infants from Betaseron, a decision should be made to either discontinue nursing or discontinue the drug, taking into account the importance of drug to the mother.

    8.4 Pediatric Use

    Safety and efficacy in pediatric patients have not been established.

    8.5 Geriatric Use

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

  • 11 DESCRIPTION

    Betaseron® (interferon beta-lb) is a purified, sterile, lyophilized protein product produced by recombinant DNA techniques. Interferon beta-1b is manufactured by bacterial fermentation of a strain of Escherichia coli that bears a genetically engineered plasmid containing the gene for human interferon betaser17. The native gene was obtained from human fibroblasts and altered in a way that substitutes serine for the cysteine residue found at position 17. Interferon beta-1b has 165 amino acids and an approximate molecular weight of 18,500 daltons. It does not include the carbohydrate side chains found in the natural material.

    The specific activity of Betaseron is approximately 32 million international units (IU)/mg interferon beta-lb. Each vial contains 0.3 mg of interferon beta-lb. The unit measurement is derived by comparing the antiviral activity of the product to the World Health Organization (WHO) reference standard of recombinant human interferon beta. Mannitol, USP and Albumin (Human), USP (15 mg each/vial) are added as stabilizers.

    Lyophilized Betaseron is a sterile, white to off-white powder, for subcutaneous injection after reconstitution with the diluent supplied (Sodium Chloride, 0.54% Solution). Albumin (Human) USP and Mannitol, USP (15 mg each/vial) are added as stabilizers.

  • 12 CLINICAL PHARMACOLOGY

    12.1 Mechanism of Action

    The mechanism of action of Betaseron (interferon beta-1b) in patients with multiple sclerosis is unknown.

    12.2 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 1 (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 inteferons 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 bioactivities 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-1b receptor binding induces the expression of proteins that are responsible for the pleiotropic bioactivities of interferon beta-1b. A number of these proteins (including neopterin, β2-microglobulin, MxA protein, and IL-10) have been measured in blood fractions from Betaseron-treated patients and Betaseron-treated healthy volunteers. Immunomodulatory effects of interferon beta-1b include the enhancement of suppressor T cell activity, reduction of pro-inflammatory cytokine production, down-regulation of antigen presentation, and inhibition of lymphocyte trafficking into the central nervous system. It is not known if these effects play an important role in the observed clinical activity of Betaseron in multiple sclerosis (MS).

    12.3 Pharmacokinetics

    Because serum concentrations of interferon beta-1b are low or not detectable following subcutaneous administration of 0.25 mg or less of Betaseron, pharmacokinetic information in patients with MS receiving the recommended dose of Betaseron is not available.

    Following single and multiple daily subcutaneous administrations of 0.5 mg Betaseron to healthy volunteers (N=12), serum interferon beta-1b concentrations were generally below 100 IU/mL. Peak serum interferon beta-1b concentrations occurred between one to eight hours, with a mean peak serum interferon concentration of 40 IU/mL. Bioavailability, based on a total dose of 0.5 mg Betaseron given as two subcutaneous injections at different sites, was approximately 50%.

    After intravenous administration of Betaseron (0.006 mg to 2 mg), similar pharmacokinetic profiles were obtained from healthy volunteers (N=12) and from patients with diseases other than MS (N=142). In patients receiving single intravenous doses up to 2 mg, increases in serum concentrations were dose proportional. Mean serum clearance values ranged from 9.4 mL/min•kg-1 to 28.9 mL/min•kg-1 and were independent of dose. Mean terminal elimination half-life values ranged from 8 minutes to 4.3 hours and mean steady-state volume of distribution values ranged from 0.25 L/kg to 2.88 L/kg. Three-times-a-week intravenous dosing for two weeks resulted in no accumulation of interferon beta-1b in sera of patients. Pharmacokinetic parameters after single and multiple intravenous doses of Betaseron were comparable.

    Following every other day subcutaneous administration of 0.25 mg Betaseron in healthy volunteers, biologic response marker levels (neopterin, β2- microglobulin, MxA protein, and the immunosuppressive cytokine, IL-10) increased significantly above baseline six-twelve hours after the first Betaseron dose. Biologic response marker levels peaked between 40 and 124 hours and remained elevated above baseline throughout the seven-day (168-hour) study. The relationship between serum interferon beta-1b levels or induced biologic response marker levels and the clinical effects of interferon beta-1b in multiple sclerosis is unknown.

    Drug Interaction Studies

    No formal drug interaction studies have been conducted with Betaseron.

  • 13 NONCLINICAL TOXICOLOGY

    13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility

    Carcinogenesis

    Betaseron has not been tested for its carcinogenic potential in animals.

    Mutagenesis

    Betaseron was not genotoxic in the in vitro Ames bacterial test or the in vitro chromosomal aberration assay in human peripheral blood lymphocytes. Betaseron treatment of mouse BALBc- 3T3 cells did not result in increased transformation frequency in an in vitro model of tumor transformation.

    Impairment of Fertility

    Administration of Betaseron (doses of up to 0.33 mg/kg/day) to normally cycling female rhesus monkeys had no apparent adverse effects on either menstrual cycle duration or associated hormonal profiles (progesterone and estradiol) when administered over three consecutive menstrual cycles. The highest dose tested is approximately 30 times the recommended human dose of 0.25 mg on a body surface area (mg/m2) basis. The potential for other effects on fertility or reproductive performance was not evaluated.

  • 14 CLINICAL STUDIES

    The clinical effects of Betaseron were studied in four randomized, multicenter, double-blind, placebo-controlled studies in patients with multiple sclerosis (Studies 1, 2, 3, and 4).

    Patients with Relapsing-Remitting Multiple Sclerosis

    The effectiveness of Betaseron in relapsing-remitting MS (RRMS) was evaluated in a double blind, multiclinic, randomized, parallel, placebo controlled clinical study of two years duration (Study 1). The study enrolled MS patients, aged 18 to 50, who were ambulatory [Kurtzke Expanded Disability Status Scale (EDSS) of ≤ 5.5 – score 5.5 is ambulatory for 100 meters, disability precludes full daily activities], exhibited a relapsing-remitting clinical course, met Poser’s criteria for clinically definite and/or laboratory supported definite MS and had experienced at least two exacerbations over two years preceding the trial without exacerbation in the preceding month. The EDSS score is a method of quantifying disability in patients with MS and ranges from 0 (normal neurologic exam) to 10 (death due to MS). Patients who had received prior immunosuppressant therapy were excluded.

    An exacerbation was defined as the appearance of a new clinical sign/symptom or the clinical worsening of a previous sign/symptom (one that had been stable for at least 30 days) that persisted for a minimum of 24 hours.

    Patients selected for study were randomized to treatment with either placebo (N=123), 0.05 mg of Betaseron (N=125), or 0.25 mg of Betaseron (N=124) self-administered subcutaneously every other day. Outcome based on the 372 randomized patients was evaluated after two years.

    Patients who required more than three 28-day courses of corticosteroids were removed from the study. Minor analgesics (acetaminophen, codeine), antidepressants, and oral baclofen were allowed ad libitum, but chronic nonsteroidal anti-inflammatory drug (NSAID) use was not allowed.

    The primary protocol-defined outcome measures were 1) frequency of exacerbations per patient and 2) proportion of exacerbation free patients. A number of secondary clinical and magnetic resonance imaging (MRI) measures were also employed. All patients underwent annual T2 MRI imaging and a subset of 52 patients at one site had MRIs performed every six weeks for assessment of new or expanding lesions.

    The study results are shown in Table 3.

    Of the 372 RRMS patients randomized, 72 (19%) failed to complete two full years on their assigned treatments.

    Over the two-year period in Study 1, there were 25 MS-related hospitalizations in the 0.25 mg Betaseron-treated group compared to 48 hospitalizations in the placebo group. In comparison, non-MS hospitalizations were evenly distributed among the groups, with 16 in the 0.25 mg Betaseron group and 15 in the placebo group. The average number of days of MS-related steroid use was 41 days in the 0.25 mg Betaseron group and 55 days in the placebo group (p=0.004).

    MRI data were also analyzed for patients in this study. A frequency distribution of the observed percent changes in MRI area at the end of two years was obtained by grouping the percentages in successive intervals of equal width. Figure 1 displays a histogram of the proportions of patients, which fell into each of these intervals. The median percent change in MRI area for the 0.25 mg group was -1.1%, which was significantly smaller than the 16.5% observed for the placebo group (p=0.0001).

    Figure Distribution of Change in MRI Area in Patients with RRMS in Study 1

    Figure_1

    In an evaluation of frequent MRI scans (every six weeks) on 52 patients at one site in Study 1, the percent of scans with new or expanding lesions was 29% in the placebo group and 6% in the 0.25 mg treatment group (p=0.006).

    The exact relationship between MRI findings and clinical status of patients is unknown. Changes in lesion area often do not correlate with changes in disability progression. The prognostic significance of the MRI findings in this study has not been evaluated.

    Patients with Secondary Progressive Multiple Sclerosis

    Studies 2 and 3 were multicenter, randomized, double-blind, placebo controlled trials conducted to assess the effect of Betaseron in patients with secondary progressive MS (SPMS). Study 2 was conducted in Europe and Study 3 was conducted in North America. Both studies enrolled patients with clinically definite or laboratory-supported MS in the secondary progressive phase, and who had evidence of disability progression (both Study 2 and 3) or two relapses (Study 2 only) within the previous two years. Baseline Kurtzke expanded disability status scale (EDSS) scores ranged from 3.0 to 6.5. Patients in Study 2 were randomized to receive Betaseron 0.25 mg (N=360) or placebo (N=358). Patients in Study 3 were randomized to Betaseron 0.25 mg (N=317), Betaseron 0.16 mg/m2 of body surface area (N=314, mean assigned dose 0.3 mg), or placebo (N=308). Test agents were administered subcutaneously, every other day for three years.

    The primary outcome measure was progression of disability, defined as a 1.0 point increase in the EDSS score, or a 0.5 point increase for patients with baseline EDSS ≥ 6.0. In Study 2, time to progression in EDSS was longer in the Betaseron treatment group (p=0.005), with estimated annualized rates of progression of 16% and 19% in the Betaseron and placebo groups, respectively. In Study 3, the rates of progression did not differ significantly between treatment groups, with estimated annualized rates of progression of 12%, 14%, and 12% in the Betaseron fixed dose, surface area-adjusted dose, and placebo groups, respectively.

    Multiple analyses, including covariate and subset analyses based on sex, age, disease duration, clinical disease activity prior to study enrollment, MRI measures at baseline and early changes in MRI following treatment were evaluated in order to interpret the discordant study results. No demographic or disease-related factors enabled identification of a patient subset where Betaseron treatment was predictably associated with delayed progression of disability.

    In Studies 2 and 3, like Study 1, a statistically significant decrease in the incidence of relapses associated with Betaseron treatment was demonstrated. In Study 2, the mean annual relapse rates were 0.42 and 0.63 in the Betaseron and placebo groups, respectively (p<0.001). In Study 3, the mean annual relapse rates were 0.16, 0.0, and 0.28, for the fixed dose, surface area-adjusted dose, and placebo groups, respectively (p<0.02).

    MRI endpoints in both Study 2 and Study 3 showed smaller increases in T2 MRI lesion area and decreased number of active MRI lesions in patients in the Betaseron groups compared to the placebo group. The exact relationship between MRI findings and the clinical status of patients is unknown. Changes in MRI findings often do not correlate with changes in disability progression. The prognostic significance of the MRI findings in these studies is not known.

    Patients with an Isolated Demyelinating Event and Typical MS Lesions on Brain MRI

    In Study 4, 468 patients who had recently (within 60 days) experienced an isolated demyelinating event, and who had lesions typical of multiple sclerosis on brain MRI were randomized to receive either 0.25 mg Betaseron (N = 292) or placebo (N= 176) subcutaneously every other day (ratio 5:3). The primary outcome measure was time to development of a second exacerbation with involvement of at least two distinct anatomical regions. Secondary outcomes were brain MRI measures, including the cumulative number of newly active lesions, and the absolute change in T2 lesion volume. Patients were followed for up to two years or until they fulfilled the primary endpoint.

    Eight percent of subjects on Betaseron and 6% of subjects on placebo withdrew from the study for a reason other than the development of a second exacerbation. Time to development of a second exacerbation was significantly delayed in patients treated with Betaseron compared to patients treated with placebo (p<0.0001). The Kaplan-Meier estimates of the percentage of patients developing an exacerbation within 24 months were 45% in the placebo group and 28% of the Betaseron group (Figure 2). The risk for developing a second exacerbation in the Betaseron group was 53% of the risk in the placebo group (Hazard ratio= 0.53; 95% confidence interval 0.39 to 0.73).

    Figure Onset of Second Exacerbation by Time in Patients with Isolated Demyelinating Event with Typical MS Lesions on Brain MRI in Study 4*

    Figure_2

    In Study 4, patients treated with Betaseron demonstrated a lower number of newly active lesions during the course of the study. A significant difference between Betaseron and placebo was not seen in the absolute change in T2 lesion volume during the course of the study.

    Safety and efficacy of treatment with Betaseron beyond three years are not known.

    What is Betaseron?

    Betaseron is a prescription medicine used to reduce the number of relapses in people 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. Betaseron is similar to certain interferon proteins that are produced in the body. It will not cure your MS but may decrease the number of flare-ups of the disease.

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

    Who should not take Betaseron?

    Do not take Betaseron if you are allergic to interfeon beta-1b, to another interferon beta, to human albumin, or mannitol. See the end of this leaflet for a complete list of ingredients in Betaseron.

    What should I tell my healthcare provider before taking Betaseron?

    Before you take Betaseron, tell your healthcare provider if you:

    have or have had depression (sinking feeling or sadness), anxiety (feeling uneasy, nervous, or fearful for no reason) or trouble sleeping
    have or have had liver problems
    have or have had blood problems such as bleeding or bruising easily, low red blood cells (anemia) or low white blood cells
    have or have had seizures
    have or have had heart problems
    are pregnant or plan to become pregnant. Betaseron can harm your unborn baby. Betaseron may cause you to lose your baby (miscarry). If you become pregnant while taking Betaseron call your healthcare provider right away. You and your healthcare provider should decide if you should continue to take Betaseron.
    are breastfeeding or plan to breastfeed. It is not known if Betaseron passes into your breast milk. You and your healthcare provider should decide if you will take Betaseron or breastfeed. You should not do both.

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

    Know the medicines you take. Keep a list of them to show your healthcare provider and pharmacist when you get a new medicine.

    How should I take Betaseron?

    See the Instructions for Use at the end of this Medication Guide for complete information on how to use Betaseron.
    Betaseron is given by injection under your skin (subcutaneous injection) every other day.
    Take Betaseron exactly as your healthcare provider tells you to take it.
    If your healthcare provider feels that you or someone else may give you the injections then you or the other person should be trained by your healthcare provider in how to give an injection.
    Do not try to give yourself or have another person give you injections until you or both of you understand and are comfortable with how to prepare your dose and give the injection.
    You may be started on a lower dose when you first start taking Betaseron. Your healthcare provider will tell you what dose of Betaseron to use.
    Your healthcare provider may change your dose of Betaseron. You should not change your dose without talking to your healthcare provider.
    If you miss a dose, you should take your next dose as soon as you remember or are able to take it. Your next injection should be taken about 48 hours (2 days) after that dose. Do not take Betaseron on 2 consecutive days. If you accidentally take more than your prescribed dose, or take it on 2 consecutive days, call your healthcare provider right away.
    Always use a new, unopened vial of Betaseron and syringe for each injection. Throw away any unused medicine. Do not reuse any vials, syringes, or needles.
    It is important for you to change your injection site each time you inject Betaseron. This will lessen the chance of you having a serious skin reaction at the site where you inject Betaseron. Avoid injecting Betaseron into an area of skin that is sore, reddened, infected or has other problems.

    What are the possible side effects of Betaseron?

    Betaseron may cause serious side effects. Call your healthcare provider right away if you have any of the serious side effects of Betaseron including:

    See “What is the most important information I should know about Betaseron?”
    heart problems. Betaseron may worsen heart problems including congestive heart failure. Symptoms of heart problems may include:
    swollen ankles
    shortness of breath
    decreased ability to exercise
    fast heartbeat
    tightness in chest
    increased need to urinate at night
    not being able to lay flat in bed
    injection site problems. Serious skin reactions can happen in some people including areas of severe damage to skin and the tissue below the skin (necrosis). These reactions can happen anywhere you inject Betaseron. Symptoms of injection site problems may include:
    swelling, redness, or pain at the injection site
    fluid drainage from the injection site
    breaks in your skin or blue-black skin discoloration
    flu-like symptoms. Betaseron can cause flu-like symptoms including:
    fever
    chills
    tiredness
    sweating
    muscle aches when you first start to use it
     
    These symptoms may decrease over time. Taking medicines for fever and pain relief on the days you are using Betaseron may help decrease these symptoms.
    seizures. Some people have had seizures while taking Betaseron, including people who have never had seizures before. It is not known if the seizures were related to their MS, to Betaseron, or to a combination of both. If you have a seizure after taking Betaseron call your healthcare provider right away.
     
    The most common side effects of Betaseron include:
    low white blood cell count
    increases in your liver enzymes
    headache
    increases in your muscle tension
    pain
    rash
    problems sleeping
    stomach pain
    weakness
     
    Tell your healthcare provider if you have any side effect that bothers you or that does not go away.
     
    These are not all the possible side effects of Betaseron. For more information, ask your healthcare provider or pharmacist.

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

    How should I store Betaseron?

    Before mixing, store Betaseron at room temperature between 68°F to 77°F (20°C to 25°C).

    Instructions for Use

    Betaseron®
    (bay-ta-seer-on)

    interferon beta-1b
    (in-ter-feer-on beta-one-be)

    Read the Instructions for Use that come with your Beteseron before you start using it and each time you get a refill. There may be new information. This leaflet does not take the place of talking to your healthcare provider about your medical condition or treatment. Before you use Beteseron for the first time, make sure your healthcare provider shows you the right way to use it.

    Supplies needed for your Betaseron Injection (See Figure A).

    1 tray containing:
    A pre-filled diluent syringe with yellow label
    A vial of Betaseron
    2 alcohol prep pads
    A blue vial adapter with a 30 gauge needle attached (in the blister pack)
     
    Figure_A

    Step 1: Preparing for Your Betaseron Injection

    Place the supplies you will need on a clean, flat surface in a well-lit area.
    Check the expiration date on the tray label to make sure that it has not expired. Do not use it if the medication has expired.
    Wash your hands thoroughly with soap and water.
    Open the tray by peeling off the label. Take out all the contents. Make sure the blister pack containing the vial adapter is sealed. Check to make sure the plastic cap on the diluent syringe is firmly attached.
    Turn the tray over, place the Betaseron vial in the well (vial holder) and place the pre-filled diluent syringe in the U-shaped trough (See Figure B).
     
    Figure_B

    Step 2: Mixing Betaseron

    Remove the Betaseron vial from the well and take the cap off the vial.
    Place the vial back into the vial holder.
    Use an alcohol prep pad to clean the top of the vial. Move the alcohol prep pad in 1 direction. Leave the alcohol prep pad on top of the vial.
    Peel the label off the blister pack with the vial adapter in it. The vial adapter is sterile. Do not remove or touch the vial adapter.
    Remove the alcohol prep pad from the top of the Betaseron vial. Pick up the vial adapter in the blister pack. Turn over the blister pack keeping the vial adapter inside. Put the adapter on top of the Betaseron vial. Push down on the adapter until it pierces the rubber top of the Betaseron vial and snaps in place ( See Figure C). Remove the blister packaging from the vial adapter.
     
    Figure_C
    Twist the plastic cap from the pre-filled diluent syringe. Throw away the plastic cap. (See Figure D)
    FIGURE_D
    Keep the vial adapter attached to the vial and remove the vial from the vial holder. Be careful not to pull the vial adapter off the top of the vial.
    Connect the pre-filled diluent syringe to the vial adapter by turning clockwise until resistance is felt and the attachment is secure. This forms the syringe assembly ( See Figure E).
    Figure_E
    Slowly push the plunger of the pre-filled diluent syringe all the way in. This will transfer all of the liquid from the syringe into the Betaseron vial ( See Figure F). The plunger may return to its original position after you release it.
    FIGURE_F
    Gently swirl the vial to completely dissolve the white powder of Betaseron. Do not shake. Shaking and even gentle mixing can cause foaming of the medicine. If there is foam, let the vial sit until the foam settles before using it.
    After the powder dissolves, look closely at the solution in the vial. Do not use the solution if it is cloudy or contains particles. It should be clear and colorless.
    Do not use cracked or damaged Betaseron vials. If your vial is cracked or damaged, get a new tray of Betaseron, prefilled syringe, vial adapter and alcohol prep pads. Repeat the steps to prepare your Betaseron dose.
    Contact BETAPLUS, a BETASERON patient support program, at 1-800-788-1467 to obtain a replacement product.

    Step 3: Preparing the Injection

    You have completed the steps to prepare your Betaseron and are ready for the injection. The injection should be given immediately after mixing and allowing any foam in the solution to settle. If you must wait to give yourself the injection, you may refrigerate the solution and use within 3 hours of mixing your Betaseron. Do not freeze.

    Push the plunger in and hold it there; then turn the syringe assembly so that the syringe is horizontal and the vial is on top.
    Slowly pull the plunger back to withdraw all the liquid from the Betaseron vial into the syringe (See Figure G).
     
    FIGURE_G
    NOTE: The syringe barrel is marked with numbers from 0.25 to 1 mL (See Figure H). If the solution in the vial cannot be drawn up to the 1 mL mark, discard the vial and syringe and start over with a new tray containing a Betaseron vial, prefilled diluent syringe, vial adapter and alcohol prep pads.
    Turn the syringe assembly so that the needle end is pointing up. Remove any air bubbles by tapping the outside of the syringe with your fingers. Slowly push the plunger to the 1 mL mark on the syringe or to the mark that matches the amount of Betaseron prescribed by your healthcare provider (See Figure H). If too much solution is pushed into the vial, repeat Step 3.
     
    Figure H
    Turn the syringe assembly so that the vial is at the bottom. Remove the blue vial adapter and the vial from the syringe by twisting the vial adapter. This will remove the vial adapter and the vial from the syringe, but will leave the needle on the syringe (See Figure I).

    Step 4. Choosing an Injection Site

    Betaseron (interferon beta-1b) is injected under the skin and into the fat layer between the skin and the muscles (subcutaneous tissue). The best areas for injection are where the skin is loose and soft and away from the joints, nerves, and bones. Do not use the area near your navel or waistline. If you are very thin, use only the thigh or outer surface of the arm for injection.
    Choose a different site each time you give yourself an injection. Figure J shows different areas for giving injections . Do not inject in the same area for 2 injections in a row. Keep a record of your injections to help make sure you change (rotate) your injection sites. You should decide where you will inject Betaseron before you prepare your medicine for injection. If there are any sites that are difficult for you to reach, you can ask someone who has been trained to give the injection to help you.
     
    FIGURE_J
    Do not inject Betaseron in a site where the skin is red, bruised, infected, or scabbed, has broken open, or has lumps, bumps, or pain. Tell your healthcare provider if you find skin conditions like the ones mentioned here or any other unusual looking areas where you have been given injections.
     
    Step 5: Injecting Betaseron
    Using a circular motion, clean the injection site with an alcohol prep pad, starting at the injection site and moving outward. Let the skin area air dry.
    Remove the cap from the needle. Hold the syringe like a pencil or dart in 1 hand.
    Gently pinch the skin around the site with the thumb and forefinger of the other hand (See Figure K). Insert the needle straight up and down into your skin at a 90° angle with a quick, dart-like motion.
     
    Figure k
    Once the needle is in your skin, slowly pull back on the plunger. If blood appears in the syringe, it means that you have entered a blood vessel. Do not inject Betaseron. Withdraw the needle. Throw away the syringe and needle in a puncture-proof container. Do not use the same syringe or any of the other supplies that you used for this injection. Repeat the steps to prepare your dose using a new tray. Choose and clean a new injection site.
    If no blood appears in the syringe, slowly push the plunger all the way in until the syringe is empty (See Figure L).
     
    FIGURE_L
    Remove the needle from the skin. Place a dry cotton ball or gauze pad over the injection site. Gently massage the injection site for a few moments with the dry cotton ball or gauze pad. Throw away the syringe in your puncture-proof disposal container.
     
    Step 6: Disposing of used syringes, needles, and vials
    To prevent needle-stick injury and spread of infection, do not try to re-cap the needle.
    Place used needles, syringes, and vials in a closeable, puncture-resistant container. You may use a sharps container (such as a red biohazard container), hard plastic container (such as a detergent bottle), or metal container (such as an empty coffee can). Do not use glass or clear plastic containers. Ask your healthcare provider for instructions on the right way to throw away (dispose of) the container. There may be state and local laws about how you should throw away used needles and syringes.
    Do not throw used needles, syringes, or vials in your household trash or recycle.
    Throw away any unused medicine. Do not save any unused Betaseron for a future dose.
    Keep the disposal container, needles, syringes, and vials of Betaseron out of the reach of children.
