Cost-effectiveness of adrenocorticotropic hormone versus oral steroids for infantile spasms.

OBJECTIVE: To compare the effectiveness and cost-effectiveness of adrenocorticotropic hormone (ACTH) and oral steroids as first-line treatment for infantile spasm resolution, we performed a systematic review, meta-analysis, and cost-effectiveness study. METHODS: A decision analysis model was populated with effectiveness data from a systematic review and meta-analysis of existing literature and cost data from publicly available prices. Effectiveness was defined as the probability of clinical spasm resolution 14 days after treatment initiation. RESULTS: We included 21 studies with a total of 968 patients. The effectiveness of ACTH was not statistically significantly different from that of oral steroids (.70, 95% confidence interval [CI] = .60-.79 vs. .63, 95% CI = .56-.70; p = .28). Considering only the three available randomized trials with a total of 185 patients, the odds ratio of spasm resolution at 14 days with ACTH compared to high-dose prednisolone (4-8 mg/kg/day) was .92 (95% CI = .34-2.52, p = .87). Adjusting for potential publication bias, estimates became even more favorable to high-dose prednisolone. Using US prices, the more cost-effective treatment was high-dose prednisolone, with an incremental cost-effectiveness ratio (ICER) of $333 per case of spasms resolved, followed by ACTH, with an ICER of $1 432 200 per case of spasms resolved. These results were robust to multiple sensitivity analyses and different assumptions. Prednisolone at 4-8 mg/kg/day was more cost-effective than ACTH under a wide range of assumptions. SIGNIFICANCE: For infantile spasm resolution 2 weeks after treatment initiation, current evidence does not support the preeminence of ACTH in terms of effectiveness and, especially, cost-effectiveness.

Industry Payments to Physician Specialists Who Prescribe Repository Corticotropin.

Importance: Despite great expense and little evidence supporting use over corticosteroids, prescriptions for repository corticotropin (H. P. Acthar Gel; Mallinckrodt Pharmaceuticals) have increased markedly. Aggressive sales tactics and payments from the manufacturer may influence prescribing behavior for this expensive medication. Objective: To characterize industry payments to physician specialists who prescribe corticotropin in the Medicare program. Design, Setting, and Participants: This study was a cross-sectional analysis of Centers for Medicare & Medicaid Services 2015 Part D prescribing data linked to 2015 Open Payments data. Nephrologists, neurologists, and rheumatologists with more than 10 corticotropin prescriptions (frequent prescribers) in 2015 were included. Exposures: Frequency, category, and magnitude of corticotropin-related payments from Mallinckrodt recorded in the Open Payments database. Main Outcomes and Measures: Frequency, category, and magnitude of corticotropin-related payments from Mallinckrodt, as well as corticotropin prescriptions and expenditures for Medicare beneficiaries. Results: Of the 235 included physicians, 65 were nephrologists; 59, neurologists; and 111, rheumatologists. A majority of frequent corticotropin prescribers (207 [88%]) received corticotropin-related payments from Mallinckrodt. The median (range) total payment for 2015 was $189 ($11-$138 321), with the highest payments ranging from $56 549 to $138 321 across the specialties. More than 20% of frequent prescribers received more than $10 000 and the top quartile of recipients received a median (range) of $33 190 ($9934-$138 321) in total payments per prescriber. Payments for compensation for services other than consulting contributed the most to the total amount. Mallinckrodt payments were positively associated with greater Medicare spending on corticotropin (ß = 1.079; 95% CI, 1.044-1.115; P < .001), with every $10 000 in payments associated with a 7.9% increase (approximately $53 000) in Medicare spending on corticotropin. There was no association between corticotropin-related payments and spending on prescriptions for synthetic corticosteroids. Conclusions and Relevance: In this study, most nephrologists, neurologists, and rheumatologists who frequently prescribe corticotropin received corticotropin-related payments from Mallinckrodt. These findings suggest that financial conflicts of interest may be driving use of corticotropin in the Medicare program.

Clinical and Economic Evaluation of Repository Corticotropin Injection: A Narrative Literature Review of Treatment Efficacy and Healthcare Resource Utilization for Seven Key Indications.

INTRODUCTION: Repository corticotropin injection (RCI; H.P. Acthar® Gel; Mallinckrodt Pharmaceuticals Inc., Hampton, NJ) is a highly purified, prolonged-release porcine preparation of adrenocorticotropic hormone (ACTH) analogue that is FDA-approved for treatment of 19 autoimmune and inflammatory disorders. The diverse physiological actions of RCI at the melanocortin receptors (MCRs) affect processes involved in inflammation, pigmentation, steroidogenesis, and immunomodulation. Although RCI has been approved to treat inflammatory and autoimmune diseases for more than 60 years, recent progress in understanding both MCRs and the effects of RCI in modulating immune responses has led to increased interest in RCI as a therapeutic choice. The objective of this narrative literature review is to summarize key clinical and economic data on RCI treatment of seven disorders: infantile spasms (IS), multiple sclerosis (MS) relapses, proteinuria in nephrotic syndrome, rheumatoid arthritis (RA), dermatomyositis/polymyositis (DM/PM), systemic lupus erythematosus (SLE), and symptomatic sarcoidosis based on published literature and product information. An extended report is available as the Academy of Managed Care Pharmacy (AMCP) Formulary dossier for H.P. Acthar® Gel. METHODS: Key studies of clinical efficacy and healthcare utilization and cost from 1956 to 2016 are summarized. RESULTS: The evidence supports the efficacy of RCI across the seven indications. RCI is effective as a first-line therapy for IS. For the other six conditions, RCI may improve clinical outcomes during exacerbations or when the condition is resistant to conventional treatments. Use of RCI is associated with reduced use of biologics, corticosteroids, and disease-modifying antirheumatic drugs. Initiation of RCI therapy in patients with IS, MS, RA, SLE, or DM/PM has been associated with lower post-therapy healthcare utilization and medical costs, including decreases in hospitalizations, hospital length of stay, outpatient visits, and emergency department visits. CONCLUSION: The evidence suggests that RCI may improve inflammatory and autoimmune disease control and patient quality of life, particularly in complex patients, and yield healthcare cost savings that demonstrate the medicine's value.

Healthcare Costs and Resource Utilization in Patients with Infantile Spasms Treated with H.P. Acthar Gel(®).

INTRODUCTION: The purpose of this study was to describe healthcare resource utilization and costs resulting from early (within 30 days of diagnosis) versus late (>30 days after diagnosis) treatment with prescriptions for H.P. Acthar(®) Gel (repository corticotropin injection; Acthar; Mallinckrodt) to manage infantile spasms (IS). METHODS: We included all patients in the Truven Health MarketScan(®) Commercial Claims and Encounters Database and the Truven Health MarketScan Multi-State Medicaid Database who were diagnosed with IS from 2007 to 2012. We performed unadjusted and adjusted regressions examining the relationship between healthcare resource utilization variables and their associated costs to compare outcomes in the early and late Acthar users. RESULTS: A total of 252 patients with IS who received Acthar fit our study criteria; 191 (76%) were early Acthar users. In adjusted analyses, we found that early Acthar use was associated with, on average, 3.8 fewer outpatient services (99% CI 0.7-6.7 fewer services). We did not find significant associations between early prescriptions for Acthar and number of hospitalizations, emergency room visits, prescription medications filled, or total costs of health services. CONCLUSION: Patients prescribed Acthar within 30 days of their IS diagnoses tended to have fewer outpatient services performed compared to patients prescribed Acthar later in the disease process. Although additional research is needed to confirm these exploratory findings, physicians may consider early treatment with Acthar to manage IS. FUNDING: This study was funded by a grant to the University of Washington from Mallinckrodt Pharmaceuticals.

Healthcare Costs and Resource Utilization in Patients with Multiple Sclerosis Relapses Treated with H.P. Acthar Gel(®).

INTRODUCTION: Multiple sclerosis (MS) is an autoimmune disorder with large annual costs. This study evaluated utilization and costs for the management of MS relapses with H.P. Acthar(®) Gel (repository corticotropin injection; Acthar; Mallinckrodt) compared to receipt of plasmapheresis (PMP) or intravenous immunoglobulin (IVIG) among patients with MS who experienced multiple relapses. METHODS: We identified patients with MS diagnoses who had relapses treated with intravenous methylprednisolone (IVMP), the first-line treatment for MS relapse. Patients who were treated for the subsequent relapses were eligible for the study. We analyzed 12- and 24-month healthcare utilization and costs among patients who received Acthar prescriptions compared to patients who were treated with PMP/IVIG using generalized linear and logistic regression models to calculate unadjusted and adjusted means and 95% confidence intervals. RESULTS: For the 12-month analysis, a total of 213 patients received Acthar prescriptions and 226 were treated with PMP or IVIG. Patients who received Acthar prescriptions were similar to those who received other treatments in terms of most demographic variables. Acthar recipients had fewer hospitalizations (0.2 vs. 0.4; P = 0.01) and received fewer outpatient services (29 vs. 43; P < 0.0001) but received more prescription medications (36 vs. 30; P < 0.0001) compared to recipients of PMP/IVIG. Patients who received Acthar prescriptions had lower inpatient and outpatient costs ($15,000 lower; P = 0.001; and $54,000 lower; P < 0.0001, respectively) but similar total costs. Similar results were seen in the cohort with 24 months of outcome data. CONCLUSION: Acthar may be a useful treatment option compared to PMP/IVIG for patients with MS experiencing multiple relapses. FUNDING: This study was funded by a grant to the University of Washington from Mallinckrodt Pharmaceuticals.

Health Care Rationing in a Just Society: The Clinical Effectiveness Model.

Representing 18% of gross domestic product, and projected to increase to 20% by 2022, health care costs in the United States are an unsustainable expense. The clinical effectiveness model of cost containment is an ethical and self-sustaining paradigm that can assist bending the health care-cost curve. As envisioned by Buyx et al, clinically effective care is aimed at making the practice of medicine more explicitly evidence based with the goals of improving clinical success, efficiency, and value. I provide a vision for applying the clinical effectiveness model to the American health care system. I illustrate its use with 2 examples from the practice of child neurology: DOC-band (helmet therapy) for the treatment of positional plagiocephaly-relatively inexpensive but ineffective, and adrenocorticotropic hormone for the treatment of infantile spasms-expensive but effective.

Effect of price increase of adrenocorticotropic hormone on treatment practices of infantile spasms.

Intramuscular adrenocorticotropic hormone putatively constitutes the most efficacious treatment for infantile spasms. Adrenocorticotropic hormone in the United States is an "orphan drug," made by a single manufacturer. The price of adrenocorticotropic hormone increased almost 14-fold on August 27, 2007. We sought to evaluate the impact of this price increase on treatment practices at our institution, using a retrospective chart review of all children with infantile spasms treated during 2007-2009. We identified 97 patients whose spasms were treated using antiepileptic drugs, and we determined the length of stay for those hospitalized to initiate adrenocorticotropic hormone. Patients before the price increase were more likely to have been treated with adrenocorticotropic hormone as first medication, and were hospitalized 2.2 +/- 0.5 S.D. days for initiation. Patients after the price increase were more likely to have been treated initially with oral antiepileptic drugs rather than adrenocorticotropic hormone (P < 0.002). Those commencing adrenocorticotropic hormone after the price increase were hospitalized significantly longer (5.1 +/- 0.6 days S.D., P < 0.001). Treatment choices need to be evidence-based, but other factors often influence them.

Outcomes in treatment of infantile spasms with pulse methylprednisolone.

The authors report their experience with intravenous methylprednisolone for the treatment of infantile spasms. A pulse dose of 20 mg/kg intravenous methylprednisolone on each of 3 successive days, followed by a 2-month oral prednisolone taper, led to the rapid remission (range, 2-6 days) of infantile spasms in 5 of 10 (50%) infants. In the subgroup of infants treated within 1 month of onset, 5 of 6 (83%) experienced remission within 6 days. The authors estimate the medication cost of intravenous methylprednisolone with prednisolone taper to be less than $200. In comparison, the cost of a typical course of adrenocorticotropic hormone in the United States can exceed $70,000. Initial treatment with intravenous methylprednisolone and/or oral corticosteroids is a reasonable cost-effective approach to infantile spasms. The lack of serious side effects, low cost, availability, ease of administration, and comparable efficacy suggests that intravenous methylprednisolone merits consideration for study in randomized prospective trials.
