Acthar may offer a different approach to targeting MS relapse

Acthar is a proprietary, prolonged-release formulation of the naturally occurring adrenocorticotropic hormone (ACTH) and other peptides.7

Acthar is believed to work with both the immune system and the central nervous system. Acthar is also believed to have steroid-dependent properties through cortisol release, as well as steroid-independent immunomodulatory properties.12-17

While the exact mechanism of action of Acthar is unknown, further investigation is being conducted. This information is based on nonclinical data and the relationship to clinical benefit is unknown.

Indication

H.P. Acthar® Gel (repository corticotropin injection) is indicated for the treatment of acute exacerbations of multiple sclerosis in adults. Controlled clinical trials have shown Acthar to be effective in speeding the resolution of acute exacerbations of multiple sclerosis. However, there is no evidence that it affects the ultimate outcome or natural history of the disease.

Important Safety Information

Contraindications
  • Acthar should never be administered intravenously.
  • Administration of live or live attenuated vaccines is contraindicated in patients receiving immunosuppressive doses of Acthar.
  • Acthar is contraindicated where congenital infections are suspected in infants.
  • Acthar is contraindicated 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 origins.

Warnings and Precautions
  • The adverse effects of Acthar are related primarily to its steroidogenic effects.
  • Acthar may increase susceptibility to new infection or reactivation of latent infections.
  • Suppression of the hypothalamic-pituitary-axis (HPA) may occur following prolonged therapy with the potential for adrenal insufficiency after withdrawal of the medication. Adrenal insufficiency may be minimized by tapering of the dose when discontinuing treatment. During recovery of the adrenal gland patients should be protected from the stress (e.g. trauma or surgery) by the use of corticosteroids. Monitor patients for effects of HPA suppression after stopping treatment.
  • Cushing’s syndrome may occur during therapy but generally resolves after therapy is stopped. Monitor patients for signs and symptoms.
  • Acthar can cause elevation of blood pressure, salt and water retention, and hypokalemia. Blood pressure, sodium and potassium levels may need to be monitored.
  • Acthar often acts by masking symptoms of other diseases/disorders. Monitor patients carefully during and for a period following discontinuation of therapy.
  • Acthar can cause GI bleeding and gastric ulcer. There is also an increased risk for perforation in patients with certain gastrointestinal disorders. Monitor for signs of bleeding.
  • Acthar may be associated with central nervous system effects ranging from euphoria, insomnia, irritability, mood swings, personality changes, and severe depression, and psychosis. Existing conditions may be aggravated.
  • Patients with comorbid disease may have that disease worsened. Caution should be used when prescribing Acthar in patients with diabetes and myasthenia gravis.
  • Prolonged use of Acthar may produce cataracts, glaucoma and secondary ocular infections. Monitor for signs and symptoms.
  • Acthar is immunogenic and prolonged administration of Acthar may increase the risk of hypersensitivity reactions. Neutralizing antibodies with chronic administration may lead to loss of endogenous ACTH activity.
  • There is an enhanced effect in patients with hypothyroidism and in those with cirrhosis of the liver.
  • Long-term use may have negative effects on growth and physical development in children. Monitor pediatric patients.
  • Decrease in bone density may occur. Bone density should be monitored for patients on long-term therapy.
  • Pregnancy Class C: Acthar has been shown to have an embryocidal effect and should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.
Adverse Reactions
  • Common adverse reactions for Acthar are similar to those of corticosteroids and include fluid retention, alteration in glucose tolerance, elevation in blood pressure, behavioral and mood changes, increased appetite and weight gain.
  • Specific adverse reactions reported in IS clinical trials in infants and children under 2 years of age included: infection, hypertension, irritability, Cushingoid symptoms, constipation, diarrhea, vomiting, pyrexia, weight gain, increased appetite, decreased appetite, nasal congestion, acne, rash, and cardiac hypertrophy. Convulsions were also reported, but these may actually be occurring because some IS patients progress to other forms of seizures and IS sometimes mask other seizures, which become visible once the clinical spasms from IS resolve.
