First Patient Enrolled in Mallinckrodt Phase 4 Trial of H.P. Acthar® Gel for Rheumatoid Arthritis
H.P. Acthar Gel is approved by the
"A significant number of patients with rheumatoid arthritis will have active symptoms and signs of joint inflammation despite the use of non-biologic and/or biologic disease modifying therapies.
About the Trial
The Phase 4 trial is titled, "A multicenter, 2-part study to assess the efficacy and safety of H.P. Acthar Gel in subjects with rheumatoid arthritis with persistently active disease." The primary endpoint of the study is to evaluate H.P. Acthar Gel treatment response, as measured by the DAS28-ESR (Disease Activity Score with 28 joint count and erythrocyte sedimentation rate) at week 12 (Part 1). Subjects who achieve low disease activity will enter a 12-week, double-blind randomized maintenance period (Part 2).
The target patient enrollment is 230. As is typical with sizeable clinical trials involving a small subset of a disease population, the company expects to take a number of years to complete the study.

About Rheumatoid Arthritis
RA is an autoimmune disease. It is a chronic condition that causes pain, stiffness, and swelling of the joints—all symptoms caused by inflammation. An estimated 1.5 million U.S. adults are living with RA.2 Treatment is aimed at stopping inflammation to put the disease in remission and relieve symptoms.3 Nonsteroidal anti-inflammatory drugs are used to ease symptoms whereas corticosteroids, disease-modifying anti-rheumatic drugs and biologics are used to slow down the disease activity.3

- Treatment of acute exacerbations of multiple sclerosis in adults.

Important Safety Information
- 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.
- 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. Cushing's Syndrome may occur during therapy but generally resolves after therapy is stopped. Monitor patients for signs and symptoms.
- Monitor patients for elevation of blood pressure, salt and water retention, and hypokalemia.
- Acthar often acts by masking symptoms of other diseases/disorders. Monitor patients carefully during and following discontinuation.
- Acthar can cause gastrointestinal (GI) bleeding and gastric ulcer with an increased risk for perforation with certain GI disorders. Monitor for signs of bleeding.
- Acthar may be associated with central nervous system effects ranging from euphoria, insomnia, irritability, mood swings, personality changes, depression, and psychosis. Existing conditions may be aggravated.
- Patients with comorbid disease may have that disease worsened. Caution should be used in patients with diabetes and myasthenia gravis.
- Prolonged use of Acthar may produce cataracts, glaucoma and secondary ocular infections.
- Acthar is immunogenic and prolonged use may increase the risk of hypersensitivity reactions.
- There is an enhanced effect in patients with hypothyroidism and those with cirrhosis of liver.
- Long-term use may have negative effects on growth and physical development in children. Monitor pediatric patients.
- Decrease in bone density may occur. Monitor during 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.
- Common adverse reactions 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 masks other seizures, which become visible once the clinical spasms from IS resolve.
