Acthar® Gel

(repository corticotropin)

Intramuscular (IM) or Subcutaneous (SQ) injection

Infantile Spasm (IS) in infants and children under 2 years of age

NOTE: Acthar is FDA approved for numerous indications, however, the FDA has only evaluated clinical trials in infants under 2 years of age with infantile spasms (7,8)

Indicated in the following disorders:

  • Acute exacerbations of multiple sclerosis (MS) in adults. Controlled clinical trials have shown Acthar Gel 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.
  • Rheumatic disorders: As adjunctive therapy for short-term administration (to tide the patient over an acute episode or exacerbation) in psoriatic arthritis, rheumatoid arthritis, including juvenile rheumatoid arthritis (selected cases may require low-dose maintenance therapy), ankylosing spondylitis.
  • Collagen diseases: during an exacerbation or as maintenance therapy in selected cases of systemic lupus erythematosus and systemic dermatomyositis (polymyositis).
  • Dermatologic diseases: severe erythema multiforme and Stevens-Johnson syndrome.
  • Allergic states: serum sickness.
  • Ophthalmic diseases: severe acute and chronic allergic and inflammatory processes involving the eye and its adnexa such as keratitis, iritis, iridocyclitis, diffuse posterior uveitis and choroiditis, optic neuritis, chorioretinitis, and anterior segment inflammation.
  • Respiratory diseases: Symptomatic sarcoidosis.
  • Edematous states: To induce a diuresis or a remission of proteinuria in the nephrotic syndrome without uremia of the idiopathic type or that due to lupus erythematosus.

Purified Cortrophin™ Gel

(repository corticotropin)

Intramuscular (IM) or Subcutaneous (SQ) injection

  • Collagen diseases: during an exacerbation or as maintenance therapy in selected cases of systemic lupus erythematosus and systemic dermatomyositis (polymyositis).
  • Dermatologic diseases: severe erythema multiforme (Stevens-Johnson syndrome) and severe psoriasis.
  • Allergic states: atopic dermatitis and serum sickness.
  • Ophthalmic diseases: severe acute and chronic allergic and inflammatory processes involving the eye and its adnexa such as allergic conjunctivitis, keratitis, iritis and iridocyclitis, diffuse posterior uveitis and choroiditis, optic neuritis, chorioretinitis, and anterior segment inflammation.
  • Respiratory diseases: Symptomatic sarcoidosis.

CLINICAL RATIONALE

CLINICAL RATIONALE

Infantile spasm (IS), also referred to as West Syndrome, is a specific seizure syndrome that is characterized by clinical flexor or extensor spasms, often involving the extremities and head/neck; developmental regression (intellectual disability); and electroencephalography (EEG) finding of hypsarrhythmia (chaotic brain waves).(2,3) Neurological and/or developmental outcomes in patients with IS are usually poor. Children with symptomatic spasms more frequently exhibit neurological deficits and cognitive and developmental delays, while a higher percentage of patients with idiopathic/cryptogenic IS may have a normal or near-normal outcome if appropriate treatment is initiated in a timely fashion. Goals of therapy for IS includes complete cessation of clinical events and resolution of hypsarrhythmia or modified hypsarrhythmia on video EEG.(3)  

 

Guidelines recommend ACTH and vigabatrin for the treatment of infantile spasms. Both ACTH and vigabatrin may be useful for short-term treatment, but ACTH is preferred over vigabatrin, except in patients with tuberous sclerosis. Hormonal therapy (ACTH or prednisolone) has been shown to lead to better neurodevelopmental outcomes in patients with cryptogenic IS when compared to vigabatrin.(2,3) Guidelines recommend treating for 14 days and then tapering down, as response is typically seen within 14 days or sooner. Low dose ACTH is probably as effective as high-dose ACTH therapy and should be considered as an alternative to high dose therapy.(2) A 2010 U.S. consensus statement suggests initiating a taper of ACTH after two weeks of therapy at the maximum dose. No data is available to guide therapy in relapse in patients who responded to an initial treatment course. Typically, a second course (four to six weeks) of the agent that was previously effective in obtaining control is administered.(4)

Efficacy

 

Acthar Gel was first approved in 1952 prior to the 1962 drug amendments requiring clinical trials proving safety and efficacy.(1,5) There are numerous phase 4 clinical trials indicating there is no difference in efficacy between corticosteroids and corticotropin for rheumatoid arthritis, lupus, multiple sclerosis, pulmonary sarcoidosis, and nephrotic syndrome.(6)   

 

The effectiveness of Acthar Gel as a treatment for infantile spasms was demonstrated in a single blinded (video EEG interpreter blinded) clinical trial in which patients were randomized to receive either a 2 week course of treatment with Acthar Gel (75 U/m^2 intramuscular twice daily) or prednisone (1 mg/kg by mouth twice daily). The primary outcome was a comparison of the number of patients in each group who were treatment responders, defined as a patient having complete suppression of both clinical spasms and hypsarrhythmia on a full sleep cycle video EEG performed 2 weeks following treatment initiation, rated by an investigator blinded to treatment. Thirteen of 15 patients (86.7%) responded to Acthar Gel as compared to 4 of 14 patients (28.6%) given prednisone (p<0.002). The 2-week treatment was followed by a 2-week period of taper. Non-responders to the prednisone treatment were eligible to receive Acthar Gel treatment. Seven of 8 patients (87.5%) responded to Acthar Gel after not responding to prednisone. Similarly, the 2 non-responder patients from the Acthar Gel treatment were eligible to receive treatment with prednisone. One of the 2 patients (50%) responded to the prednisone treatment after not responding to Acthar Gel.(1)

 

A supportive single-blind, randomized clinical trial comparing high-dose, long-duration treatment (150 U/m^2 once daily for 3 weeks, n=30) of Acthar Gel with low-dose, short duration treatment (20 U once daily for 2 weeks, n=29) for the treatment of infantile spasms was also evaluated in infants and children less than 2 years of age. Non-responders (defined as in the previously described study) in the low-dose group received a dose escalation at 2 weeks to 30 U once daily. Nominal statistical superiority of the high dose treatment, as compared to the low dose treatment, was observed for cessation of spasms but not for the resolution of hypsarrhythmia.(1)

 

There is no clinical data for the FDA indication for Cortrophin Gel. No additional clinical trials for Cortrophin were completed to show efficacy for the approved indications.(9)
