An open-label, 24-week study of Acthar® Gel used in 11 adults with refractory and active DM/PM who needed an alternative to glucocorticoids and/or conventional immunosuppressive agents1

Objective

To evaluate the efficacy, safety, tolerability, and glucocorticoid-sparing effect of Acthar Gel in an open-label, 24-week, proof-of-concept study of 11 adults with refractory and active DM/PM*

*Ten of the 11 enrolled patients completed the study. One patient dropped out due to heart block unrelated to the study drug and was not included in the efficacy analysis, as she did not complete the minimum 8 weeks of the study drug required for outcome assessment per study protocol.

Study Design1

  • A 24-week proof-of-concept study of 11 adults with refractory and active DM/PM*
  • Refractory disease defined as failing an adequate glucocorticoid trial (≥2 months of high doses [0.75 mg/kg to 1 mg/kg] or intolerance to such therapy) and/or ≥1 conventional immunosuppressive agent
  • Active disease defined as having:
  • Baseline Manual Muscle Testing (MMT-8) score ≤125 out of 150 and ≥2 additional abnormal core set measures (CSMs), or
  • DM with cutaneous 10-cm visual analog scale (VAS) score ≥3 cm on the Myositis Disease Activity Assessment Tool (MDAAT) and at least 3 other abnormal CSMs (excluding the MMT-8)
  • All patients received 80 units of Acthar Gel twice weekly for 24 weeks

Study Assessments1

Primary endpoint

  • Three of any of the 6 CSMs improved by ≥20%, with no more than 2 CSMs worsening by ≥25%, based on IMACS definition of improvement (DOI)
  • Worsening measure could not include MMT
  • Primary endpoint was also separately evaluated on a subset of patients with severe muscle weakness (defined as an MMT score of ≤125 out of 150 at baseline), as well as moderate to severe cutaneous DM rashes (defined as a cutaneous VAS score ≥2.5 out of 10 at baseline)

Secondary endpoints

  • Median change in 6 individual CSMs
  • Median time to definition of improvement (DOI) from baseline
  • 2016 American College of Rheumatology (ACR)/European League Against Rheumatism (EULAR) myositis response criteria
  • Mean change in glucocorticoid dose at 24 weeks
  • Secondary safety and tolerability endpoints were measured by frequency and type of adverse and severe adverse events (AEs and SAEs)

AE=adverse event; IMACS=International Myositis Assessment and Clinical Studies Group; SAE=serious adverse event.

Concomitant immunosuppressive agents or glucocorticoids were allowed as long as patients were on these therapies for ≥8 weeks (and ≥4 weeks for glucocorticoids) and on a stable dose for ≥4 weeks and ≥2 weeks, respectively, prior to the start of the trial.

Patient Characteristics1

DM/PM patients had chronic and persistent disease activity and were previously treated with other regimens1

rheum-23
SD=standard deviation.

Study Limitations1

  • Efficacy results are based on 10 patients who completed the study
  • This study may not be fully representative of outcomes in the overall patient population
  • Sample bias may exist, as this was an open-label study
  • All patients were on multiple therapies; therefore, the clinical outcomes may not be solely attributable to Acthar Gel
  • Acthar Gel has not been formally studied in combination with other treatments

70% of patients (n=7) met the primary endpoint after treatment with Acthar Gel1

Primary Endpoint1

  • Seven out of 10 patients completing the study met the IMACS DOI by a median of 8 weeks (interquartile range=4 to 20 weeks) after treatment with Acthar Gel
  • DM and PM patients did not differ in their response to treatment

Primary endpoint: definition of improvement

Acthar Gel DM/PM study results: IMACS DOI

Results Pie Chart
Bar Graph

Patients showed improvements in several CSMs

  • MMT improved by 10.7% in all patients
    • Seven patients with severe muscle weakness at baseline showed median improvement of 15.3%
  • MD Global improved by >43% in all 10 patients
  • Extramuscular Global Assessment improved by 10.7% in all patients
    • Patients with moderate to severe rash at baseline showed improvement of 20%

Results are based on 10 patients who completed the study. This study may not be fully representative of outcomes in the overall patient population. All patients were on multiple therapies; therefore, the clinical outcomes may not be solely attributable to Acthar Gel. Acthar Gel has not been formally studied in combination with other treatments.

*Ten of the 11 enrolled patients completed the study.

Criteria for improvement were based on the 2016 ACR/EULAR myositis response criteria.

Metric derived from the 2016 ACR/EULAR myositis response criteria, which corresponds to magnitude of improvement.

Safety ENDPOINTS1

Many of the observed AEs were similar to those seen with glucocorticoids. Other factors typically associated with high-dose steroids given for an extended period, such as significant weight gain, diabetes, or Cushingoid features, were not observed.

  • A total of 5 SAEs were observed in 3 patients
    • Of these SAEs, 3 were related to the study drug
    • Two patients experienced herpes zoster infections and required hospitalization, including 1 patient with disseminated herpes zoster causing herpes pneumonitis
  • A total of 22 AEs were observed in 8 patients, all related to the study drug

INDICATIONS

Acthar® Gel is indicated for:

  • Treatment during an exacerbation or as maintenance therapy in selected cases of dermatomyositis (polymyositis)​
  • Treatment during an exacerbation or as maintenance therapy in selected cases of systemic lupus erythematosus​
  • 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​
  • Symptomatic sarcoidosis
  • 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, anterior segment inflammation​
  • Inducing a diuresis or a remission of proteinuria in nephrotic syndrome without uremia of the idiopathic type or that due to lupus erythematosus​
  • 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​
  • Monotherapy for the treatment of infantile spasms in infants and children under 2 years of age

Important Safety information

Contraindications

Acthar 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
  • 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

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-adrenal (HPA) axis 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 axis 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. Monitor blood pressure and sodium and potassium levels
  • 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 gastrointestinal (GI) bleeding and gastric ulcer. There is also an increased risk for perforation in patients with certain GI disorders. Monitor for signs of perforation and bleeding
  • Acthar may be associated with central nervous system effects ranging from euphoria, insomnia, irritability, mood swings, personality changes, and severe depression to 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. Cases of anaphylaxis have been reported in the postmarketing setting. Neutralizing antibodies with chronic administration may lead to loss of endogenous ACTH and Acthar activity
  • There may be 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 in patients on long-term therapy

Adverse Reactions

  • Commonly reported postmarketing adverse reactions for Acthar include injection site reaction, asthenic conditions (including fatigue, malaise, asthenia, and lethargy), fluid retention (including peripheral swelling), insomnia, headache, and blood glucose increased
  • The most common adverse reactions for the treatment of infantile spasms (IS) are increased risk of infections, convulsions, hypertension, irritability, and pyrexia. Some patients with IS progress to other forms of seizures; IS sometimes masks these seizures, which may become visible once the clinical spasms from IS resolve

Pregnancy

  • Acthar may cause fetal harm when administered to a pregnant woman
