5 Warnings and Precautions

5.3 Elevated Blood Pressure, Salt and Water Retention, and Hypokalemia

Additions and/or revisions underlined:

Acthar Gel can cause elevation of blood pressure, salt and water retention, and increased excretion of potassium and calcium. Dietary salt restriction and potassium supplementation may be necessary. Caution should be used in the treatment of patients with hypertension or renal insufficiency. Acthar Gel is contraindicated in patients with congestive heart failure [see Contraindications (4)].

5 Warnings and Precautions

5.10 Immunogenicity Potential

Additions and/or revisions underlined:

Acthar Gel is immunogenic. Limited available data suggest that a patient may develop antibodies to Acthar Gel after chronic administration and loss of endogenous ACTH and Acthar Gel activity. Prolonged administration of Acthar Gel may increase the risk of hypersensitivity reactions. Cases of anaphylaxis have been reported in the postmarketing setting. Use in patients with sensitivity to porcine protein is contraindicated, and the possibility of sensitivity should be considered during the course of treatment should symptoms arise.

6 Adverse Reactions

6.2 Postmarketing Experience

Additions and/or revisions double underlined:

The following adverse reactions have been identified during post approval use of Acthar Gel.

Because adverse 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.

Allergic Reactions

Allergic responses have presented as dizziness, nausea, and anaphylaxis (anaphylactic shock, hypotension, respiratory compromise, urticaria, edema).

Cardiovascular

Necrotizing angitis (adults only), congestive heart failure, atrial fibrillation, and palpitations.

Dermatologic

Skin thinning (adults only), facial erythema, and increased sweating (adults only).

Endocrine

Decreased carbohydrate tolerance (infants only), hirsutism, and menstrual irregularities.

Gastrointestinal

Pancreatitis (adults only), abdominal distention, and ulcerative esophagitis.

General Disorders and Administration Site Conditions

Injection site reaction and asthenic conditions (including fatigue, malaise, asthenia, and lethargy).

Infections and Infestations

Abscess.

Investigations

Blood glucose increased.

Metabolic

Hypokalemic alkalosis (infants only) and fluid retention (including peripheral swelling).

Musculoskeletal

Muscle weakness and vertebral compression fractures (infants only).

Neurological

Headache (adults only), vertigo (adults only), subdural hematoma, intracranial hemorrhage (adults only), and reversible brain shrinkage (usually secondary to hypertension) (infants only).

Psychiatric Disorders

Insomnia.

8 Use in Specific Populations

8.1 Pregnancy

PLLR conversion:

Risk Summary

Based 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 Considerations

Fetal-Neonatal Adverse Reactions

Hypoadrenalism 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)].

8.2 Lactation

PLLR conversion:

Risk Summary

There are no available data on the presence of corticotropin in either human or animal milk, the effects on the breastfed infant, or on milk production. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for Acthar Gel and any potential adverse effects on the breastfed infant from Acthar Gel or from the underlying maternal condition.
