🩺 Clinical
Glatiramer injection is used to treat various forms of multiple sclerosis (MS; a disease that damages nerves and can cause weakness, numbness, trouble walking or talking, vision changes, and other problems). Glatiramer is in a class of medications called immunomodulators. It works by stopping the body from damaging its own nerve cells (myelin).

( 5.7 )
5.1Anaphylactic Reactions Life-threatening and fatal anaphylaxis has been reported with glatiramer acetate injection [see Adverse Reactions ( 6.2 )]. Glatiramer acetate injection is contraindicated in patients with a history of hypersensitivity reactions to glatiramer acetate injection, including anaphylaxis [see Contraindications ( 4 )] . Anaphylaxis can occur at any time following initiation glatiramer acetate injection therapy, from as early as after the first dose, up to years after initiation of treatment.
Anaphylaxis occurred within an hour of a glatiramer acetate injection in most of the reported cases. Some signs and symptoms of anaphylactic reactions may overlap with those of immedicate post-injection reactiongs [see Warnings and Precautions ( 5.2 )]. All patients receiving treatment with glatiramer acetate injection and caregivers should be informed about the signs and symptoms of anaphylactic reactions, and that they must seek immediate emergency medical care in case of experiencing such symptoms.
If an anaphylactic reaction occurs, treatment with glatiramer acetate injection must be immediately discontinued. Unless a clear alternative etiology is identified, glatiramer acetate injection must be permanently discontinued [see Contraindications ( 4 )].
5.2Immediate Post-Injection Reaction Approximately 16% of patients exposed to glatiramer acetate injection 20 mg per mL in the 5 placebo-controlled trials compared to 4% of those on placebo, and approximately 2% of patients exposed to glatiramer acetate injection 40 mg per mL in a placebo-controlled trial compared to none on placebo, experienced a constellation of symptoms that may occur immediately (within seconds to minutes, with the majority of symptoms observed within 1 hour) after injection and included at least two of the following: flushing, chest pain, palpitations, tachycardia, anxiety, dyspnea, constriction of the throat, and urticaria.
These events are termed immediate post-injection reactions. The symptoms of an immediate post-injetcion reaction may overlap with those of anaphylaxis; prompt identification of anaphylaxis is important to avoid a delay in treatment. In general, symptoms of an immediate post-injection reaction have 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. Typically, the symptoms were transient and self-limited and did not require treatment; however, there have been reports of patients with similar symptoms who developed fatal anaphylaxis and/or 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.
5.3Chest Pain Approximately 13% of glatiramer acetate injection 20 mg per mL patients in the 5 placebo-controlled studies compared to 6% of placebo patients, and approximately 2% of patients exposed to glatiramer acetate…

6.1Clinical 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 practice. Incidence in Controlled Clinical Trials Glatiramer Acetate Injection 20 mg per mL per day Among 563 patients treated with glatiramer acetate injection 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 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 injection than in patients treated with placebo. Adverse reactions were usually mild in intensity.

👥 Use in Specific Populations ▾
8 USE IN SPECIFIC POPULATIONS
8.1Pregnancy Risk Summary Available data from pharmacovigilance and published observational studies over decades of use with glatiramer acetate during pregnancy have not identified a drug-associated risk of major birth defects, miscarriage, or other adverse maternal or fetal outcomes ( see Data ). Administration of glatiramer acetate by subcutaneous injection to pregnant rats and rabbits resulted in no adverse effects on embryofetal or offspring development (see Data ) . The background risk of major birth defects and miscarriage for the indicated population is unknown.
All pregnancies have a background risk of birth defect, loss, or other outcomes. In the US general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively. Data Human Data Data from pharmacovigilance and published observational studies have not identified a drug-associated risk of major birth defects, miscarriage, or other adverse maternal or fetal outcomes when glatiramer acetate was used during pregnancy.
However, the published comparative observational studies have methodological limitations, such as short exposure duration during pregnancy, confounding, selection bias, and exposure misclassification. Animal Data In rats or rabbits receiving glatiramer acetate by subcutaneous injection during the period of organogenesis, no adverse effects on embryofetal 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/m 2 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.
8.2Lactation Risk Summary There are no data on the presence of glatiramer acetate in human milk. Based on the low systemic exposure because of substantial local hydrolysis of glatiramer acetate following subcutaneous administration, breastfeeding is not expected to result in clinically relevant exposure of the infant to the drug [see Clinical Pharmacology (12.3) ] . There are no data on the effects of glatiramer acetate on milk production.
The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for glatiramer acetate injection and any potential adverse effects on the breastfed infant from glatiramer acetate injection or from the underlying maternal condition.
8.4Pediatric Use The safety and effectiveness of glatiramer acetate injection have not been established in patients under 18 years of age.
8.5Geriatric Use Glatiramer acetate injection has not been studied in elderly patients.
8.6Use in Patients with Impaired Renal Function The pharmacokinetics of glatiramer acetate in patients with impaired renal function have not been determined.

🧬 Clinical Pharmacology ▾
12 CLINICAL PHARMACOLOGY
12.1Mechanism 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 (5.5) ] .
12.3Pharmacokinetics 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.

📋 Description ▾
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 – 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 ● x CH 3 COOH (C 5 H 9 NO 4 ● C 3 H 7 NO 2 ● C 6 H 14 N 2 O 2 ● C 9 H 11 NO 3 ) x ● x C 2 H 4 O 2 CAS - 147245-92-9 Glatiramer acetate injection is a clear, colorless to slightly yellow, sterile, nonpyrogenic solution for subcutaneous injection. Each 1 mL of Glatiramer Acetate Injection solution contains 20 mg or 40 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.
💬 Information for Patients ▾
17 PATIENT COUNSELING INFORMATION Advise the patient to read the FDA-approved patient labeling ( Medication Guide and Instructions for Use ). Important Administration Instructions Advise patients with new or existing glatiramer acetate prescriptions to consult their pharmacist or healthcare provider if they would like information about using an optional compatible autoinjector device, if available. Additionally, advise patients who would like to use an autoinjector for administration, should one be available, that not all available autoinjectors are compatible with all glatiramer acetate products and the availability of compatible autoinjectors may change with time.
If you have questions about the availability or compatibility of an autoinjector, contact the manufacturer of the prescribed glatiramer acetate product for more information. Advise patients that using an optional autoinjector that is not compatible with the glatiramer acetate product may increase the risk for medication errors, such as missing a dose or administration of a partial dose [see Dosage and Administration (2.2) , Warnings and Precautions (5.7) ] . Anaphylactic Reactions Advise patients and their caregivers that glatiramer acetate injection may cause life-threatening and fatal anaphylactic reactions shortly after injection, and that reactions may occur months to years after initiation of treatment [see Warnings and Precautions (5.1) ] .
Inform patients and their caregivers about the signs and symptoms specific for anaphylactic reactions, and that signs and symptoms of anaphylactic reactions may overlap with those of immediate post-injection reactions. Instruct them to seek immediate emergency medical care if they experience any signs or symptoms of an anaphylactic reaction [see Warnings and Precautions (5.1 , 5.2) ] . Patients should be advised to also contact their healthcare provider, and that treatment should be discontinued immediately and permanently if anaphylactic reactions occur.
Immediate Post-Injection Reaction Advise patients that glatiramer acetate may cause immediate post-injection reactions, characterized by various symptoms after injection, including flushing, chest pain, palpitations, tachycardia, anxiety, dyspnea, constriction of the throat, and urticaria [see Warnings and Precautions (5.2) ] . These symptoms occur within seconds to minutes after injection and are generally transient, self-limited, and do not require specific treatment. Inform patients that these symptoms may occur early or may have their onset several months after the initiation of treatment.
A patient may experience one or several episodes of these symptoms. Advise patients that the symptoms of an immediate post-injection reaction may overlap with those of an anaphylactic reaction. Advise patients to contact their healthcare provider if they experience any signs or symptoms of an immediate post-injection reaction [see Warnings and Precautions (5.1 , 5.2) ] .
Chest Pain Advise patients that they may experience transient chest pain either as part of the Immediate Post-Injection Reaction or in isolation [see Warnings and Precautions (5.3) ] .
