`FULL PRESCRIBING INFORMATION
`COPAXONE (glatiramer acetate)
`
`1 INDICATIONS AND USAGE
`COPAXONE is indicated for reduction of the frequency of relapses in patients
`with Relapsing-Remitting Multiple Sclerosis (RRMS), including patients who have
`experienced a first clinical episode and have MRI features consistent with multiple
`sclerosis.
`
`2 DOSAGE AND ADMINISTRATION
`2.1 Recommended Dose
`COPAXONE is for subcutaneous use only. Do not administer intravenously.
`The recommended dose of COPAXONE is 20 mg/day.
`
`2.2 Instructions for Use
`Remove one blister that contains the syringe from the COPAXONE prefilled
`syringes package. Since this product should be refrigerated, let the prefilled syringe
`
`stand at room temperature for 20 minutes to allow the solution to warm to room
`temperature. Inspect the COPAXONE syringe visually for particulate matter and
`discoloration prior to administration, whenever solution and container permit. The
`solution in the syringe should appear clear, colorless to slightly yellow. If particulate
`matter or discoloration is observed, discard the COPAXONE syringe.
`Areas for self-injection include arms, abdomen, hips, and thighs. The prefilled
`syringe is for single use only. Discard unused portions.
`
`3 DOSAGE FORMS AND STRENGTHS
`Single-use prefilled syringe containing 1 mL solution with 20 mg of glatiramer
`acetate and 40 mg of mannitol.
`
`4 CONTRAINDICATIONS
`COPAXONE is contraindicated in patients with known hypersensitivity to
`glatiramer acetate or mannitol.
`
`5 WARNINGS AND PRECAUTIONS
`
`5.1 Immediate Post-Injection Reaction
`
`
`Approximately 16% of patients exposed to COPAXONE in the 5 placebo-
`
`controlled trials compared to 4% of those on placebo experienced a constellation of
`symptoms immediately after injection that included at least two of the following:
`
`flushing, chest pain, palpitations, anxiety, dyspnea, constriction of the throat, and
`urticaria. The symptoms were generally transient and self-limited and did not require
`treatment. In general, these symptoms have their onset several months after the
`initiation of treatment, although they may occur earlier, and a given patient may
`experience one or several episodes of these symptoms. Whether or not any of these
`symptoms actually represent a specific syndrome is uncertain. During the
`
`MYLAN INC. EXHIBIT NO. 1052 Page 3
`
`
`
`
`
`postmarketing period, there have been reports of patients with similar symptoms
`who received emergency medical care.
`
`Whether an immunologic or nonimmunologic mechanism mediates these
`episodes, or whether several similar episodes seen in a given patient have identical
`mechanisms, is unknown.
`
`
`5.2 Chest Pain
`
`Approximately 13% of COPAXONE patients in the 5 placebo-controlled
`studies compared to 6% of placebo patients experienced at least one episode of
`what was described as transient chest pain. While some of these episodes occurred
`in the context of the Immediate Post-Injection Reaction described above, many did
`not. The temporal relationship of this chest pain to an injection of COPAXONE was
`not always known. The pain was transient (usually lasting only a few minutes), often
`unassociated with other symptoms, and appeared to have no clinical sequelae.
`Some patients experienced more than one such episode, and episodes usually
`began at least 1 month after the initiation of treatment. The pathogenesis of this
`symptom is unknown.
`
`
`5.3 Lipoatrophy and Skin Necrosis
`
`At injection sites, localized lipoatrophy and, rarely, injection site skin necrosis
`have been reported during the postmarketing experience. Lipoatrophy may occur at
`various times after treatment onset (sometimes after several months) and is thought
`to be permanent. There is no known therapy for lipoatrophy. To assist in possibly
`minimizing these events, the patient should be advised to follow proper injection
`technique and to rotate injection sites daily.
`
`
`5.4 Potential Effects on Immune Response
`Because COPAXONE can modify immune response, it may interfere with
`immune functions. For example, treatment with COPAXONE may interfere with the
`recognition of foreign antigens in a way that would undermine the body's tumor
`surveillance and its defenses against infection. There is no evidence that
`COPAXONE does this, but there has not been a systematic evaluation of this risk.
`Because COPAXONE is an antigenic material, it is possible that its use may lead to
`the induction of host responses that are untoward, but systematic surveillance for
`these effects has not been undertaken.
`Although COPAXONE is intended to minimize the autoimmune response to
`myelin, there is the possibility that continued alteration of cellular immunity due to
`chronic treatment with COPAXONE may result in untoward effects.
`Glatiramer acetate-reactive antibodies are formed in most patients exposed to
`daily treatment with the recommended dose. Studies in both the rat and monkey
`have suggested that immune complexes are deposited in the renal glomeruli.
`Furthermore, in a controlled trial of 125 RRMS patients given COPAXONE, 20 mg,
`subcutaneously every day for 2 years, serum IgG levels reached at least 3 times
`baseline values in 80% of patients by 3 months of initiation of treatment. By 12
`
`
`
`
`
`2
`
`
`MYLAN INC. EXHIBIT NO. 1052 Page 4
`
`
`
`months of treatment, however, 30% of patients still had IgG levels at least 3 times
`baseline values, and 90% had levels above baseline by 12 months. The antibodies
`are exclusively of the lgG subtype and predominantly of the lgG-1 subtype. No lgE
`type antibodies could be detected in any of the 94 sera tested; nevertheless,
`anaphylaxis can be associated with the administration of most any foreign
`substance, and therefore, this risk cannot be excluded.
`
`6 ADVERSE REACTIONS
`
`
`6.1 Clinical Trials Experience
`
`Because clinical trials are conducted under widely varying conditions, adverse
`reaction rates observed in the clinical trials of a drug cannot be directly compared to
`rates in the clinical trials of another drug and may not reflect the rates observed in
`clinical practice.
`
`Incidence in Controlled Clinical Trials
`
`
`Among 563 patients treated with COPAXONE in blinded placebo controlled
`trials, approximately 5% of the subjects discontinued treatment because of an
`adverse reaction. The adverse reactions most commonly associated with
`discontinuation were: injection site reactions, dyspnea, urticaria, vasodilatation, and
`hypersensitivity. The most common adverse reactions were: injection site reactions,
`vasodilatation, rash, dyspnea, and chest pain.
`Table 1 lists treatment-emergent signs and symptoms that occurred in at least
`
`2% of patients treated with COPAXONE in the placebo-controlled trials. These signs
`and symptoms were numerically more common in patients treated with COPAXONE
`than in patients treated with placebo. Adverse reactions were usually mild in
`intensity.

`
`
`
`Adverse reactions which occurred only in 4-5 more subjects in the
`COPAXONE group than in the placebo group (less than 1% difference), but for
`which a relationship to COPAXONE could not be excluded, were arthralgia and
`herpes simplex.
`Laboratory analyses were performed on all patients participating in the clinical
`program for COPAXONE. Clinically significant laboratory values for hematology,
`chemistry, and urinalysis were similar for both COPAXONE and placebo groups in
`blinded clinical trials. In controlled trials one patient discontinued treatment due to
`thrombocytopenia (16 x109/L), which resolved after discontinuation of treatment.
`Data on adverse reactions occurring in the controlled clinical trials were
`analyzed to evaluate differences based on sex. No clinically significant differences
`were identified. Ninety-six percent of patients in these clinical trials were Caucasian.
`The majority of patients treated with COPAXONE were between the ages of 18 and
`45. Consequently, data are inadequate to perform an analysis of the adverse
`reaction incidence related to clinically relevant age subgroups.
`
`
`Other Adverse Reactions
`In the paragraphs that follow, the frequencies of less commonly reported
`adverse clinical reactions are presented. Because the reports include reactions
`observed in open and uncontrolled premarketing studies (n= 979), the role of
`COPAXONE in their causation cannot be reliably determined. Furthermore,
`variability associated with adverse reaction reporting, the terminology used to
`describe adverse reactions, etc., limit the value of the quantitative frequency
`estimates provided. Reaction frequencies are calculated as the number of patients
`who used COPAXONE and reported a reaction divided by the total number of
`patients exposed to COPAXONE. All reported reactions are included except those
`
`already listed in the previous table, those too general to be informative, and those
`not reasonably associated with the use of the drug. Reactions are further classified
`within body system categories and enumerated in order of decreasing frequency
`using the following definitions: Frequent adverse reactions are defined as those
`occurring in at least 1/100 patients and infrequent adverse reactions are those
`occurring in 1/100 to 1/1,000 patients.

`
`
`
`
`
`7
`
`
`MYLAN INC. EXHIBIT NO. 1052 Page 9
`
`
`
`interactions of COPAXONE with therapies commonly used in MS patients, including
`the concurrent use of corticosteroids for up to 28 days. COPAXONE has not been
`formally evaluated in combination with interferon beta.
`
`8 USE IN SPECIFIC POPULATIONS
`
`
`8.1 Pregnancy
`
`Pregnancy Category B.
`
`Administration of glatiramer acetate by subcutaneous injection to pregnant
`rats and rabbits resulted in no adverse effects on offspring development. There are
`no adequate and well-controlled studies in pregnant women. Because animal
`reproduction studies are not always predictive of human response, COPAXONE
`should be used during pregnancy only if clearly needed.
`
`In rats or rabbits receiving glatiramer acetate by subcutaneous injection
`during the period of organogenesis, no adverse effects on embryo-fetal development
`were observed at doses up to 37.5 mg/kg/day (18 and 36 times, respectively, the
`therapeutic human dose of 20 mg/day on a mg/m2 basis). In rats receiving
`subcutaneous glatiramer acetate at doses of up to 36 mg/kg from day 15 of
`pregnancy throughout lactation, no significant effects on delivery or on offspring
`growth and development were observed.
`
`
`8.2 Labor and Delivery
`The effects of COPAXONE on labor and delivery in pregnant women are
`unknown.
`
`8.3 Nursing Mothers
`It is not known if glatiramer acetate is excreted in human milk. Because many
`drugs are excreted in human milk, caution should be exercised when COPAXONE is
`administered to a nursing woman.
`
`8.4 Pediatric Use
`The safety and effectiveness of COPAXONE have not been established in
`patients under 18 years of age.
`
`8.5 Geriatric Use
`COPAXONE has not been studied in elderly patients.
`
`8.6 Use in Patients with Impaired Renal Function
`The pharmacokinetics of glatiramer acetate in patients with impaired renal
`function have not been determined.
`
`11 DESCRIPTION
`COPAXONE is the brand name for glatiramer acetate (formerly known as
`copolymer-1). Glatiramer acetate, the active ingredient of COPAXONE, consists of
`the acetate salts of synthetic polypeptides, containing four naturally occurring amino
`
`
`
`
`
`8
`
`MYLAN INC. EXHIBIT NO. 1052 Page 10
`
`
`
`acids: L-glutamic acid, L-alanine, L-tyrosine, and L-lysine with an average molar
`fraction of 0.141, 0.427, 0.095, and 0.338, respectively. The average molecular
`weight of glatiramer acetate is 5,000 – 9,000 daltons. Glatiramer acetate is
`identified by specific antibodies.
`Chemically, glatiramer acetate is designated L-glutamic acid polymer with
`L-alanine, L-lysine and L-tyrosine, acetate (salt). Its structural formula is:
`
`
`(Glu, Ala, Lys, Tyr)x ●xCH3COOH
`(C5H9NO4●C3H7NO2●C6H14N2O2●C9H11NO3)x ●xC2H4O2
`
`CAS - 147245-92-9
`
`COPAXONE is a clear, colorless to slightly yellow, sterile, nonpyrogenic
`solution for subcutaneous injection. Each 1 mL of solution contains 20 mg of
`glatiramer acetate and 40 mg of mannitol. The pH range of the solution is
`approximately 5.5 to 7.0. The biological activity of COPAXONE is determined by its
`
`ability to block the induction of experimental autoimmune encephalomyelitis (EAE) in
`mice.
`
`
`12 CLINICAL PHARMACOLOGY
`12.1 Mechanism of Action
`
`The mechanism(s) by which glatiramer acetate exerts its effects in patients
`with MS are not fully understood. However, glatiramer acetate is thought to act by
`modifying immune processes that are believed to be responsible for the
`pathogenesis of MS. This hypothesis is supported by findings of studies that have
`been carried out to explore the pathogenesis of experimental autoimmune
`encephalomyelitis, a condition induced in animals through immunization against
`central nervous system derived material containing myelin and often used as an
`experimental animal model of MS. Studies in animals and in vitro systems suggest
`that upon its administration, glatiramer acetate-specific suppressor T-cells are
`induced and activated in the periphery.
`Because glatiramer acetate can modify immune functions, concerns exist
`about its potential to alter naturally occurring immune responses. There is no
`evidence that glatiramer acetate does this, but this has not been systematically
`evaluated [see Warnings and Precautions (5.4)].
`
`12.2 Pharmacokinetics
`
`Results obtained in pharmacokinetic studies performed in humans (healthy
`volunteers) and animals support that a substantial fraction of the therapeutic dose
`delivered to patients subcutaneously is hydrolyzed locally. Larger fragments of
`glatiramer acetate can be recognized by glatiramer acetate-reactive antibodies.
`Some fraction of the injected material, either intact or partially hydrolyzed, is
`presumed to enter the lymphatic circulation, enabling it to reach regional lymph
`nodes, and some may enter the systemic circulation intact.

`
`In a 2-year carcinogenicity study, mice were administered up to 60 mg/kg/day
`glatiramer acetate by subcutaneous injection (up to 15 times the human therapeutic
`dose of 20 mg/day on a mg/m2 basis). No increase in systemic neoplasms was
`observed. In males receiving the 60-mg/kg/day dose, there was an increased
`incidence of fibrosarcomas at the injection sites. These sarcomas were associated
`with skin damage precipitated by repetitive injections of an irritant over a limited skin
`
`area.
`
`In a 2-year carcinogenicity study, rats were administered up to 30 mg/kg/day
`glatiramer acetate by subcutaneous injection (up to 15 times the human therapeutic
`dose on a mg/m2 basis). No increase in neoplasms was observed.
`Glatiramer acetate was not mutagenic in in vitro (Ames test, mouse
`lymphoma tk) assays. Glatiramer acetate was clastogenic in two separate in vitro
`
`chromosomal aberration assays in cultured human lymphocytes but not clastogenic
`in an in vivo mouse bone marrow micronucleus assay.
`When glatiramer acetate was administered by subcutaneous injection prior to
`and during mating (males and females) and throughout gestation and lactation
`(females) at doses up to 36 mg/kg/day (18 times the human therapeutic dose on a
`mg/m2 basis) no adverse effects were observed on reproductive or developmental
`parameters.
`
`14 CLINICAL STUDIES
`14.1 Relapsing-Remitting Multiple Sclerosis (RRMS)
`
`
`Evidence supporting the effectiveness of COPAXONE in decreasing the
`frequency of relapses derives from 3 placebo-controlled trials, all of which used a
`COPAXONE dose of 20 mg/day.
`Study 1 was performed at a single center. Fifty patients were enrolled and
`randomized to receive daily doses of either COPAXONE, 20 mg subcutaneously, or
`placebo (COPAXONE: n=25; placebo: n=25). Patients were diagnosed with RRMS
`by standard criteria, and had had at least 2 exacerbations during the 2 years
`immediately preceding enrollment. Patients were ambulatory, as evidenced by a
`score of no more than 6 on the Kurtzke Disability Scale Score (DSS), a standard
`scale ranging from 0–Normal to 10–Death due to MS. A score of 6 is defined as one
`at which a patient is still ambulatory with assistance; a score of 7 means the patient
`
`must use a wheelchair.
`Patients were examined every 3 months for 2 years, as well as within several
`days of a presumed exacerbation. To confirm an exacerbation, a blinded neurologist
`had to document objective neurologic signs, as well as document the existence of
`
`other criteria (e.g., the persistence of the neurological signs for at least 48 hours).
`The protocol-specified primary outcome measure was the proportion of
`patients in each treatment group who remained exacerbation free for the 2 years of
`the trial, but two other important outcomes were also specified as endpoints: the
`frequency of attacks during the trial, and the change in the number of attacks
`
`compared with the number which occurred during the previous 2 years.
`Table 2 presents the values of the three outcomes described above, as well
`as several protocol specified secondary measures. These values are based on the

`
`In both studies, COPAXONE exhibited a clear beneficial effect on relapse
`rate, and it is based on this evidence that COPAXONE is considered effective.
`
`In Study 3, 481 patients who had recently (within 90 days) experienced an
`isolated demyelinating event and who had lesions typical of multiple sclerosis on
`brain MRI were randomized to receive either COPAXONE 20 mg/day (n=243) or
`placebo (n=238). The primary outcome measure was time to development of a
`second exacerbation. Patients were followed for up to three years or until they
`reached the primary endpoint. Secondary outcomes were brain MRI measures,
`including number of new T2 lesions and T2 lesion volume.
`Time to development of a second exacerbation was significantly delayed in
`patients treated with COPAXONE compared to placebo (Hazard Ratio = 0.55; 95%
`confidence interval 0.40 to 0.77; Figure 1). The Kaplan-Meier estimates of the
`percentage of patients developing a relapse within 36 months were 42.9% in the
`placebo group and 24.7% in the COPAXONE group.

`Patients treated with COPAXONE demonstrated fewer new T2 lesions at the
`last observation (rate ratio 0.41; confidence interval 0.28 to 0.59; p < 0.0001).
`Additionally, baseline-adjusted T2 lesion volume at the last observation was lower
`for patients treated with COPAXONE (ratio of 0.89; confidence interval 0.84 to 0.94;
`p = 0.0001).
`
`Study 4 was a multinational study in which MRI parameters were used both
`as primary and secondary endpoints. A total of 239 patients with RRMS
`(COPAXONE: n=119; and placebo: n=120) were randomized. Inclusion criteria were
`similar to those in the second study with the additional criterion that patients had to
`have at least one Gd-enhancing lesion on the screening MRI. The patients were
`treated in a double-blind manner for nine months, during which they underwent
`monthly MRI scanning. The primar
