- Infantile spasms: doses must be administered intramuscularly using the Acthar gel vial. The recommended dose is 150 U/m2 divided into twice daily injections of 75 U/m2. After 2 weeks of treatment dosing should be gradually tapered and discontinued over a 2-week period. Acthar Gel single-dose pre-filled SelfJect injector is not to be used for the treatment of infantile spasms ()
2.2 Recommended Dosage for Infantile Spasms in Infants and Children Under 2 Years of AgeIn the treatment of infantile spasms, Acthar Gel must be administered intramuscularly using the Acthar gel vial. Do not use the Acthar Gel single-dose pre-filled SelfJect injector for the treatment of infantile spasms. The recommended regimen is a daily dose of 150 U/m2(divided into twice daily intramuscular (IM) injections of 75 U/m2) administered over a 2-week period. Dosing with Acthar Gel should then be gradually tapered over a 2-week period to avoid adrenal insufficiency. The following is one suggested tapering schedule: 30 U/m2in the morning for 3 days; 15 U/m2in the morning for 3 days; 10 U/m2in the morning for 3 days; and 10 U/m2every other morning for 6 days.
Acthar Gel is typically dosed based on body surface area (BSA). For calculation of body surface area, use the following formula:


Equation Formula - Acute exacerbations of multiple sclerosis: daily intramuscular or subcutaneous doses of 80 to 120 units for 2-3 weeks may be administered. It may be necessary to taper the dose. ()
2.3 Recommended Dosage for the Treatment of Acute Exacerbations in Adults with Multiple SclerosisThe recommended dose is daily intramuscular or subcutaneous doses of 80 to 120 units for 2-3 weeks for acute exacerbations.
Dosage should be individualized according to the medical condition of each patient. Frequency and dose of the drug should be determined by considering the severity of the disease and the initial response of the patient.
Although drug dependence does not occur, sudden withdrawal of Acthar Gel after prolonged use may lead to adrenal insufficiency or recurrent symptoms which make it difficult to stop the treatment. It may be necessary to taper the dose and increase the injection interval to gradually discontinue the medication.
- Other disorders and diseases: individualize dosing depending on the disease and patient. The usual dose is 40 to 80 units given intramuscularly or subcutaneously every 24 to 72 hours. It may be necessary to taper the dose. ()
2.4 Recommended Dosage for Other Indications for Adults and Children Over 2 Years of AgeDosage should be individualized according to the disease under treatment and the general medical condition of each patient. Frequency and dose of the drug should be determined by considering severity of the disease and the initial response of the patient.
The usual dose of Acthar Gel is 40 to 80 units given intramuscularly or subcutaneously every 24 to 72 hours.
Although drug dependence does not occur, sudden withdrawal of Acthar Gel after prolonged use may lead to adrenal insufficiency or recurrent symptoms which make it difficult to stop the treatment. It may be necessary to taper the dose and increase the injection interval to gradually discontinue the medication.
Injection available as:
400 USP Units/5 mL (80 USP Units/mL) in a multi-dose vial for subcutaneous or intramuscular injection.
40 USP Units/0.5 mL in a single-dose pre-filled SelfJect injector for subcutaneous injection.
80 USP Units/mL in a single-dose pre-filled SelfJect injector for subcutaneous injection.
Acthar Gel (repository corticotropin injection) is a clear light amber solution mobile at room temperature.
- Pediatric Use: Prolonged use of Acthar Gel in children may inhibit skeletal growth. If use is necessary, it should be given intermittently with careful observation. (,
5.12 Negative Effects on Growth and Physical DevelopmentLong-term use of Acthar Gel may have negative effects on growth and physical development in pediatric patients. Changes in appetite are seen with Acthar Gel therapy, with the effects becoming more frequent as the dose or treatment period increases. These effects are reversible once Acthar Gel therapy is stopped. Growth and physical development of pediatric patients on prolonged therapy should be carefully monitored.
, and5.13 Decrease in Bone DensityDecrease in bone formation and an increase in bone resorption both through an effect on calcium regulation (i.e., decreasing absorption and increasing excretion) and inhibition of osteoblast function may occur. These, together with a decrease in the protein matrix of the bone (secondary to an increase in protein catabolism) and reduced sex hormone production, may lead to inhibition of bone growth in children and adolescents and to the development of osteoporosis at any age. Special consideration should be given to patients at increased risk of osteoporosis (i.e., postmenopausal women) before initiating therapy, and bone density should be monitored in patients on long term therapy.
)8.4 Pediatric UseActhar Gel is indicated as monotherapy for the treatment of infantile spasms in infants and children less than 2 years of age. Both serious and other adverse reactions can occur in this population
[see Warnings and Precautions (5)and Adverse Reactions (6.1)].The efficacy of Acthar Gel for the treatment of infantile spasms in infants and children less than 2 years of age was evaluated in a randomized, single blinded (video EEG interpreter blinded) clinical trial and an additional active control supportive trial
[see Clinical Studies (14)]. A responding patient was defined as having both complete cessation of spasms and elimination of hypsarrhythmia.Safety in the pediatric population for infantile spasms was evaluated by retrospective chart reviews and data from non-sponsor conducted clinical trials
[see Adverse Reactions (6.1)]. While the types of adverse reactions seen in infants and children under 2 years of age treated for infantile spasms are similar to those seen in older patients, their frequency and severity may be different due to the very young age of the infant, the underlying disorder, the duration of therapy and the dosage regimen. Effects on growth are of particular concern[see Warnings and Precautions (5.12)]. Serious adverse reactions observed in adults may also occur in children[see Warnings and Precautions (5)]. - Pregnancy: May cause fetal harm. ()
8.1 PregnancyRisk SummaryBased on Acthar Gel's pharmacological effect of stimulating an endogenous steroid response
[see Clinical Pharmacology ( 12.1)], Acthar Gel may cause fetal harm when administered to a pregnant woman. The published literature on systemic corticosteroid use during pregnancy, which may be relevant, suggests potential concerns. Intrauterine growth restriction, decreased birth weight, and preterm birth have been reported with maternal use of corticosteroids; however, the underlying maternal condition may also contribute to these risks. Hypoadrenalism has also been reported in infants after high-dose and/or long-term use of corticosteroids during pregnancy(see Clinical Considerations). The potential adverse developmental effects of Acthar Gel have not been adequately assessed in animals.The estimated background risk of major birth defects and miscarriage for the indicated population(s) is unknown. All pregnancies have a background risk of birth defects, loss, or other adverse outcomes. In the U.S. 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.
Clinical ConsiderationsFetal-Neonatal Adverse ReactionsHypoadrenalism has been reported in infants born to mothers treated with systemic corticosteroids during pregnancy. Infants born to mothers treated with Acthar Gel should be carefully observed for signs of hypoadrenalism, such as poor feeding, irritability, weakness, and vomiting, and managed accordingly
[see Warnings and Precautions (5.2)].
Acthar Gel is contraindicated:
- for intravenous administration.
- in infants under 2 years of age who have suspected congenital infections.
- with concomitant administration of live or live attenuated vaccines in patients receiving immunosuppressive doses of Acthar Gel.
- in patients with scleroderma, osteoporosis, systemic fungal infections, ocular herpes simplex, recent surgery, history of or the presence of a peptic ulcer, congestive heart failure, uncontrolled hypertension, primary adrenocortical insufficiency, adrenocortical hyperfunction, or sensitivity to proteins of porcine origin.
