Mallinckrodt Will Conduct Phase 4 Trial of H.P. Acthar® Gel (Repository Corticotropin Injection) for Symptomatic Sarcoidosis

STAINES-UPON-THAMES, United Kingdom, Oct. 9, 2017 /PRNewswire/ -- Mallinckrodt plc (NYSE: MNK), a leading global specialty pharmaceutical company, today announced it will conduct a new Phase 4, multi-center, randomized, double blind, placebo-controlled study to further assess the efficacy of H.P. Acthar Gel as a therapy option in patients with symptomatic sarcoidosis, one of 19 indications approved by the U.S. Food and Drug Administration (FDA).

"In my experience, a considerable number of sarcoidosis patients can have persistent disease that may not be resolved by first line treatment," said Dr. Robert Baughman, M.D., Professor from Department of Internal Medicine, University of Cincinnati Medical Center, Cincinnati, Ohio.1 "The results from this sarcoidosis Phase 4 study in this patient population can potentially provide substantial evidence to further support Acthar as a treatment option in appropriate symptomatic sarcoidosis patients."

"We are pleased to announce our plans to initiate this study of the efficacy of Acthar therapy as a later line treatment option for sarcoidosis patients with persistent disease," said Steven Romano, M.D., Chief Scientific Officer and Executive Vice President at Mallinckrodt. "H.P Acthar Gel is new to many pulmonologists and the new phase 4 study – a 'pilot' study in 100 patients – is being designed as an exploratory evaluation of a subset of the more challenging patients, many of whom may not have responded to multiple previous therapies. The study will help us better understand and outline for physicians which patients may benefit from a treatment alternative like Acthar – perhaps those who aren't responding to traditional treatments."

Further details will be available on www.clinicaltrials.gov in the near future with the study's posting, and updated upon enrollment of the first subjects expected in early 2018.

About Symptomatic Sarcoidosis
Sarcoidosis is a challenging, yet treatable, rare multisystem disease. In some cases the symptoms may come and go throughout a lifetime. This is referred to as symptomatic sarcoidosis.2 In people with sarcoidosis the immune system overreacts, forming clumps of cells called granulomas that result in inflammation to the body's tissues.2 The disease can impact any organ, but it most often impacts the lungs, lymph nodes, eyes, and skin.2 Over 90 percent of people with sarcoidosis will suffer lung problems.2 Concomitant involvement of organs outside of the lungs is common, occurring in as many as half of all sarcoidosis cases.3

About H.P. Acthar Gel (repository corticotropin injection)
Indications
H.P. Acthar Gel is an injectable drug approved by the FDA for the treatment of 19 indications. Of these, today the majority of Acthar use is in these indications:

  • Treatment during an exacerbation or as maintenance therapy in selected cases of systemic lupus erythematosus
  • Monotherapy for the treatment of infantile spasms in infants and children under 2 years of age
  • The treatment of acute exacerbations of multiple sclerosis in adults. Controlled clinical trials have shown H.P. 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
  • Inducing a diuresis or a remission of proteinuria in nephrotic syndrome without uremia of the idiopathic type or that due to lupus erythematosus
  • Treatment during an exacerbation or as maintenance therapy in selected cases of systemic dermatomyositis (polymyositis)
  • The treatment of symptomatic sarcoidosis
  • Adjunctive therapy for short-term administration (to tide the patient over an acute episode or exacerbation) in rheumatoid arthritis, including juvenile rheumatoid arthritis (selected cases may require low-dose maintenance therapy)
  • Treatment of 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

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

Other adverse events reported are included in the full Prescribing Information.
