– Findings from nine human factors studies, assessing design and user interface, suggest SelfJect functions as an effective delivery device when used as intended1 –
– The SelfJect delivery device received the Arthritis Foundation's Ease of Use certification –
DUBLIN, Sept. 17, 2024 /PRNewswire/ -- Mallinckrodt plc, a global specialty pharmaceutical company, today announced the publication of findings from seven formative and two validation human factors studies of recently launched Acthar Gel (repository corticotropin injection) Single-Dose Pre-filled SelfJect™ Injector ("SelfJect").2 The manuscript, describing the formative and human factor outcomes, was recently published online in Expert Opinion on Drug Delivery. Approved by the U.S. Food and Drug Administration (FDA) in February of 2024, SelfJect also received the Arthritis Foundation's Ease of Use® certification. This certification recognizes SelfJect for its easy-to-use design, based on testing by an independent third party.
Acthar Gel is a naturally sourced complex mixture of adrenocorticotropic hormone (ACTH) analogs and other pituitary peptides.2 Acthar Gel is approved by the FDA for the treatment of several autoimmune disorders and medical conditions known to cause inflammation.2 SelfJect is available in 40 USP units/0.5 mL and 80 USP units/1.0 mL injectors and must be administered by people 18 years of age or older. SelfJect is not to be used for the treatment of infantile spasms.
Please see Indications and Important Safety Information for Acthar Gel below.
"We're proud of the extensive research and testing conducted to develop SelfJect, including these human factors studies which were critical to our application for FDA approval," said
Lisa French, Executive Vice President & Chief Commercial Officer. "These results, and the Arthritis Foundation's Ease of Use certification, are a testament to our commitment to modernize Acthar Gel for our patient community. In keeping with our mission of listening for needs, SelfJect provides an administration option designed to better support patients, caregivers, and medical professionals in managing appropriate conditions."
Arthritis Foundation President and CEO Steven Taylor said, "Ease of Use products and packaging are designed to help people with arthritis and those with physical limitations by making everyday tasks easier. We're excited to partner with companies like Mallinckrodt that understand the importance of developing products and packages with the needs of patients at the forefront."
About the Studies
Human factors studies were conducted utilizing SelfJect to assess the design of the injection device and its user interface, as well as mitigate potential use-related hazards, through observation of participants using the device and participant feedback.1 The published research includes results from nine studies, including seven formative studies, a validation study (with four prior pilot validation studies), and a supplemental validation study with participants including lay users, patients, caregivers, and healthcare providers.1 The formative studies tested and developed various components such as packaging and instructional material, whereas the validation study evaluated administration of the device with the intended-to-market user interface and representative users in representative simulated-use environments.1 Four pilot studies then generated additional protocol recommendations for the validation study.1
In the 160-participant validation study, 91% (n=146) of participants successfully administered their first injection, with 98% (n=156) cumulative success after the second trial.1 Use errors were rare with simulated-use (6.9% [n=194] of all evaluated tasks) and knowledge-based (1.6% [n=56] of all evaluated tasks) testing. The most common use errors were related to not appropriately warming the product before administration.1
Limitations of the studies include1:
The controlled study setting may not have accurately replicated real-world complexities that play a role in the administration of Acthar Gel via SelfJect, potentially altering the number of study use errors and deviation.
Injections were performed with placebo gel into an injection pad and not a patient. The feedback that a user receives when injecting into skin versus a surrogate injection pad may influence use behavior.
A more realistic delivery container could have been used to cue the participant that this product would arrive cold and would need to be stored appropriately.
Participant selection bias, reliance on self-reported and qualitative data, and small sample sizes in the formative and pilot studies may have impacted results.

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