5.4 Potential Effects on Immune Response
Because glatiramer acetate can modify immune response, it may interfere with immune functions. For example, treatment with glatiramer acetate 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 glatiramer acetate does this, but there has not been a systematic evaluation of this risk. Because glatiramer acetate 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 glatiramer acetate is intended to minimize the autoimmune response to myelin, there is the possibility that continued alteration of cellular immunity due to chronic treatment with glatiramer acetate may result in untoward effects.
Glatiramer acetate-reactive antibodies are formed in most patients receiving glatiramer acetate. 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 glatiramer acetate injection 20 mg per mL, 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 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 IgG subtype and predominantly of the IgG-1 subtype. No IgE 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
Glatiramer Acetate Injection 20 mg per mL per Day
Among 563 patients treated with glatiramer acetate 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 glatiramer acetate injection 20 mg per mL in the placebo-controlled trials. These signs and symptoms were numerically more common in patients treated with glatiramer acetate than in patients treated with placebo. Adverse reactions were usually mild in intensity.

Adverse reactions which occurred only in 4 to 5 more subjects in the glatiramer acetate group than in the placebo group (less than 1% difference), but for which a relationship to glatiramer acetate could not be excluded, were arthralgia and herpes simplex.
Laboratory analyses were performed on all patients participating in the clinical program for glatiramer acetate. Clinically-significant laboratory values for hematology, chemistry, and urinalysis were similar for both glatiramer acetate 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 of glatiramer acetate injection 20 mg per mL 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 glatiramer acetate 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 glatiramer acetate 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 glatiramer acetate and reported a reaction divided by the total number of patients exposed to glatiramer acetate. 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 DRUG INTERACTIONS
Interactions between glatiramer acetate and other drugs have not been fully evaluated. Results from existing clinical trials do not suggest any significant interactions of glatiramer acetate with therapies commonly used in MS patients, including the concurrent use of corticosteroids for up to 28 days. Glatiramer acetate has not been formally evaluated in combination with interferon beta.Close
- 8 USE IN SPECIFIC POPULATIONS
Teratogenic Effects. 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, glatiramer acetate 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 glatiramer acetate 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 glatiramer acetate is administered to a nursing woman.
8.4 Pediatric Use
The safety and effectiveness of glatiramer acetate have not been established in patients under 18 years of age.
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
Glatiramer acetate, the active ingredient of glatiramer acetate injection, consists of the acetate salts of synthetic polypeptides, containing four naturally occurring amino 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 to 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
CAS - 147245-92-9
Glatiramer acetate is a clear, colorless to slightly yellow, sterile, nonpyrogenic solution for subcutaneous injection. Each 1 mL of glatiramer acetate solution contains 20 mg of glatiramer acetate and the following inactive ingredient: 40 mg of mannitol. The pH of the solutions is approximately 5.5 to 7.0. The biological activity of glatiramer acetate is determined by its ability to block the induction of experimental autoimmune encephalomyelitis (EAE) in mice.Close
- 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)].
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.
- 13 NONCLINICAL TOXICOLOGY
13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility
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
Evidence supporting the effectiveness of glatiramer acetate derives from four placebo-controlled trials which used a glatiramer acetate injection dose of 20 mg per mL per day.
Glatiramer Acetate Injection 20 mg per mL per Day: Study 1 was performed at a single center. Fifty patients were enrolled and randomized to receive daily doses of either glatiramer acetate injection, 20 mg per mL subcutaneously, or placebo (glatiramer acetate injection: 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 intent-to-treat population (i.e., all patients who received at least 1 dose of treatment and who had at least 1 on-treatment assessment):

Study 2 was a multicenter trial of similar design which was performed in 11 U.S. centers. A total of 251 patients (glatiramer acetate injection: n = 125; placebo: n = 126) were enrolled. The primary outcome measure was the Mean 2-Year Relapse Rate. Table 3 presents the values of this outcome for the intent-to-treat population, as well as several secondary measures:

Mean Change in DSS
In both studies, glatiramer acetate exhibited a clear beneficial effect on relapse rate, and it is based on this evidence that glatiramer acetate 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 glatiramer acetate injection 20 mg per mL (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 glatiramer acetate 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 glatiramer acetate group.
Figure 1: Time to Second Exacerbation
Patients treated with glatiramer acetate 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 glatiramer acetate (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 (glatiramer acetate: 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 primary endpoint for the double-blind phase was the total cumulative number of T1 Gd-enhancing lesions over the nine months. Table 4 summarizes the results for the primary outcome measure monitored during the trial for the intent-to-treat cohort.

How should I use glatiramer acetate injection?
- For detailed instructions, see the Instructions for Use at the end of this leaflet for complete information on how to use glatiramer acetate injection .
- Your doctor will tell you how much glatiramer acetate injection to use and when to use it.
- Glatiramer acetate injection is given by injection under your skin (subcutaneously).
- Use glatiramer acetate injection exactly as your doctor tells you to use it.
- Since every body type is different, talk with your doctor about the injection areas that are best for you.
- You should receive your first dose of glatiramer acetate injection with a doctor or nurse present. This might be at your doctor’s office or with a visiting home health nurse who will teach you how to give your glatiramer acetate injections.
What are the possible side effects of glatiramer acetate injection?
Glatiramer acetate injection may cause serious side effects, including:
Post-Injection Reactions. Serious side effects may happen right after you inject glatiramer acetate injection at any time during your course of treatment. Call your doctor right away if you have any of these post-injection reaction symptoms including:
- redness to your cheeks or other parts of the body (flushing)
- chest pain
- fast heart beat

Do not re-use your glatiramer acetate prefilled syringes.
Do not share your glatiramer acetate prefilled syringes with another person. You may give another person an infection or get an infection from them.
You should receive your first dose of glatiramer acetate injection with a doctor or nurse present. This might be at your doctor’s office or with a visiting home health nurse who will show you how to give your own injections.
Glatiramer acetate injection comes in a 20 mg Prefilled Syringe with needle attached. Your doctor will prescribe the correct dose for you.
Instructions for using your glatiramer acetate 20 mg prefilled syringe dose:
- Glatiramer acetate injection 20 mg is injected 1 time each day, in the fatty layer under your skin (subcutaneously).
- Each glatiramer acetate 20 mg prefilled syringe is for single use (1 time use) only.
- The glatiramer acetate injection 20 mg dose is packaged in boxes of 30 prefilled syringes with needles attached.
How do I inject glatiramer acetate injection?
Step 1: Gather the supplies you will need to inject glatiramer acetate injection. See Figure A.
- 1 blister pack with a glatiramer acetate prefilled syringe with needle attached
- Alcohol wipe (not supplied)
- Dry cotton ball (not supplied)
- A place to record your injections, like a notebook (not supplied)
- Sharps disposal container (not supplied). See Step 13 below, “Dispose of needles and syringes”.
Step 2: Remove only 1 blister pack from the glatiramer acetate prefilled syringe carton. See
- Place the supplies you will need on a clean, flat surface in a well-lit area.
- After you remove 1 blister pack from the carton, keep all unused syringes in the carton and store them in the refrigerator.
- Let the blister pack, with the syringe inside, warm to room temperature for about 20 minutes.
- Wash your hands. Be careful not to touch your face or hair after washing your hands.
Step 3: Look closely at your glatiramer acetate prefilled syringe.
- There may be small air bubbles in the syringe. Do not try to push the air bubble from the syringe before giving your injection so you do not lose any medicine.
- Check the liquid medicine in the syringe before you give your injection. The liquid in the syringe should look clear, and colorless, and may look slightly yellow. If the liquid is cloudy or contains any particles, do not use the syringe and throw it away in a sharps disposal container. See Step 13 below, “Dispose of needles and syringes.”
Step 4: Choose your injection area. See Figure C.
See the injection areas you should use on your body. Talk with your doctor about the injection areas that are best for you.
The possible injection areas on your body include
(See Figure C):
- your stomach area (abdomen) around the belly button
- the back of your upper arms
- upper hips (below your waist)
- your thighs (above your knees)
- For each glatiramer acetate injection dose, choose a different injection area from 1 of the areas shown above. See Figure C.
- Do not stick the needle in the same place (site) more than 1 time each week. Each injection area contains multiple injection sites for you to choose from. Avoid injecting in the same site over and over again.
- Keep a record of the sites where you give your injection each day so you will remember where you already injected.
Step 5: Prepare to give your injection.
- There are some injection areas on your body that are hard to reach (like the back of your arm). You may need help from someone who has been instructed on how to give your injection if you cannot reach certain injection areas.
- Do not inject in sites where the skin has scarring or “dents”. Using scarred or dented skin for your injections may make your skin worse.
Step 6: Clean your injection site.
- Clean the injection site using the alcohol wipe and allow your skin to air dry. See Figure D.
Step 7: Pick up the syringe with 1 hand and hold it like a pencil. Remove the needle cover with your other hand and set it aside. See Figure E.
Step 8: Pinch about a 2 inch fold of skin between your thumb and index finger. See Figure F.
Step 9: Giving your injection.
- Rest the heel of your hand holding the syringe against your skin at the injection site. Insert the needle at a 90 degree angle straight into your skin. See Figure G.
- When the needle is all the way into your skin, release the fold of skin. See Figure H.
Step 10: Give your glatiramer acetate injection.
To inject the medicine, hold the syringe steady and slowly push down the plunger. See Figure I.
Step 11: Remove the needle.
After you have injected all of the medicine, pull the needle straight out. See Figure J.
Step 12: Use a clean, dry cotton ball to gently press on the injection site for a few seconds. Do not rub the injection site or re-use the needle or syringe. See Figure K.
Step 13: Dispose of your needles and syringes.
- Put your used needles and syringes in a FDA-cleared sharps disposal container right away after use. Do not throw away (dispose of) loose needles and syringes in your household trash.
If you do not have a FDA-cleared sharps disposal container, you may use a household container that is:
- made of a heavy-duty plastic,
- can be closed with a tight-fitting, puncture-resistant lid, without sharps being able to come out,
- upright and stable during use,
- leak-resistant, and
- properly labeled to warn of hazardous waste inside the container.
- When your sharps disposal container is almost full, you will need to follow your community guidelines for the right way to dispose of your sharps disposal container. There may be state or local laws about how you should throw away used needles and syringes. For more information about safe sharps disposal, and for specific information about sharps disposal in the state that you live in, go to the FDA’s website at: http://www.fda.gov/safesharpsdisposal.
- Do not dispose of your used sharps disposal container in your household trash unless your community guidelines permit this. Do not recycle your used sharps disposal container.
