DUBLIN, July 1, 2021 /PRNewswire/ -- Mallinckrodt plc (OTCMKTS: MNKKQ), a global biopharmaceutical company, today announced new treatment guidelines for sarcoidosis from the European Respiratory Society (ERS), which include use of Acthar® Gel (repository corticotropin injection) therapy in the clinical management of certain patients with pulmonary sarcoidosis, published in European Respiratory Journal.1 The treatment guidelines are the first ERS-issued evidence-based clinical practice recommendations, aimed at providing guidance to physicians treating sarcoidosis patients, to include Acthar Gel. In addition, the guidelines support existing consensus recommendations on the use of Acthar Gel in the management of patients with pulmonary sarcoidosis based on a recent U.S. Sarcoidosis Expert Panel Consensus Statement, previously published in European Respiratory Review.2
Acthar Gel is approved by the U.S. Food and Drug Administration (FDA) for the treatment of symptomatic sarcoidosis and is only commercially available in the U.S.3 Please see Important Safety Information for Acthar Gel below.
The guidelines—developed by a ERS Task Force committee composed of clinicians, methodologists and patient advocates with experience in sarcoidosis—list Acthar Gel among the various anti-inflammatory treatments for pulmonary sarcoidosis and note it can be used on a case-by-case basis when other therapies are ineffective or not tolerated. Additionally, the guidelines state that recent studies have suggested the effectiveness of Acthar Gel as a steroid-sparing agent in advanced sarcoidosis. The guidelines acknowledge that the potential mechanisms of action of Acthar Gel have not been fully elucidated and that its understanding has continued to evolve with further research.1 Mallinckrodt continues to invest in studies to advance the characterization of the proposed mechanisms of action and to better understand the efficacy and safety profiles of Acthar Gel.
"Sarcoidosis is a multisystem disorder that almost always affects the lungs. The condition can be debilitating for many patients and in some cases become serious or life-threatening, which is why it is important to recognize those patients with progressive disease and manage them appropriately," said Robert Baughman, M.D., Pulmonologist at University of Cincinnati Health, lead author of the ERS guidelines and contributing author of the U.S. Sarcoidosis Expert Panel Consensus Statement. "The new ERS guidelines, along with the expert panel consensus statement, provide practical guidance to physicians of the role of Acthar Gel in the clinical management of sarcoidosis based on the combined clinical experience of experts in the field, creating consensus around the real-world use of Acthar Gel in treating patients with this disease."
The U.S. Sarcoidosis Expert Panel Consensus Statement published in European Respiratory Review includes guidance on dosage, concomitant medications and adverse event (AE) management of advanced sarcoidosis with Acthar Gel. The panel, comprised of 12 independent physicians with expertise in treating patients with sarcoidosis, recommended a starting dose of Acthar Gel 40 units twice a week for most patients with less severe disease, but did not achieve consensus on whether a higher initial dose was indicated for patients with a more severe condition. In addition, Acthar Gel should be continued at a maintenance dose for most patients who respond to therapy, particularly those with chronic refractory/advanced sarcoidosis, and the maintenance dose should be individualized for each patient. If patients develop major adverse events, the recommendations suggested considering reducing or discontinuing Acthar Gel. The panel also made recommendations related to discontinuation of therapy, including weaning to the lowest efficacious dose if the patient has stable, well-controlled disease after six to 12 months of therapy.2
Study limitations include the following: There are no generally accepted criteria for consensus. The study is based on a degree of consensus, which may be refuted by future rigorous studies. Panelists were not accountable for their responses, and opinions may be based on insufficient/minimal consideration. Panel selection and questionnaire development may introduce bias, and perspectives from stakeholders other than U.S.-based physicians may have been missed.
Regarding the use of concomitant medications, the panel recommended that concomitant steroids be tapered and potentially discontinued as quickly as possible in patients receiving Acthar Gel, but concomitant use of immunosuppressive medications should be continued. Consensus recommendations were also reached for AE management, including that Acthar Gel be titrated down or discontinued if other interventions fail or if AEs are severe and significant.2
"There has been a need for quite some time for evidence-based consensus on the treatment of sarcoidosis, a rare disease that can significantly impact patients' functioning and quality of life and can be difficult to diagnose and treat," said Steven Romano, M.D., Executive Vice President and Chief Scientific Officer at Mallinckrodt. "The ERS guidelines will help fill knowledge gaps in clinical care and enable more standardized treatment of symptomatic sarcoidosis to help improve clinical outcomes for patients. Moreover, both the guidelines and the sarcoidosis expert panel consensus statement provide practical, expert guidance on the use of Acthar Gel for physicians who manage patients with this complex disease."
Mallinckrodt has a dedicated team to support healthcare providers and patients throughout a patient's treatment regimen including personalized injection training.
Sarcoidosis is a challenging, yet manageable, rare multisystem disease.4,5 In some cases the symptoms may come and go throughout one's lifetime. This is referred to as symptomatic sarcoidosis. In people living with sarcoidosis, the immune system overreacts, forming clumps of cells called granulomas that result in inflammation of the body's tissues.6 The disease can impact any organ but most often impacts the lungs, lymph nodes, eyes, and skin.4 Over 90 percent of people with sarcoidosis suffer lung problems.6 Concomitant involvement of organs outside of the lungs is common, occurring in as many as half of all sarcoidosis cases.7
IMPORTANT SAFETY INFORMATION
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. 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
- 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
- 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
Other adverse events reported are included in the full Prescribing Information.
