INTRODUCTION: About 20%-35% of multiple sclerosis (MS) patients fail to respond to high-dose corticosteroids during a relapse. Repository corticotropin injection (RCI, Acthar® Gel) is a naturally sourced complex mixture of adrenocorticotropic hormone analogs and pituitary peptides that has anti-inflammatory and immunomodulatory effects. AIMS: The study objective was to determine the efficacy and safety of RCI in patients with MS relapse that inadequately responded to corticosteroids...

PURPOSE: Approximately 6% of patients with rheumatoid arthritis (RA) in the USA have refractory disease that is resistant to standard-of-care therapies. A recent phase IV clinical trial affirmed the safety and efficacy of repository corticotropin injection (RCI; Acthar® Gel) for refractory RA. This post hoc analysis of the clinical trial data assessed whether changes in clinical measures correlated with patient-reported outcome (PRO) improvements. METHODS: Data were assessed from the trial's open-label period when patients received RCI (80 U) twice weekly for 12 weeks...

IMPORTANCE: Repository corticotropin injection is an expensive medication that was approved in 1952 for the treatment of many inflammatory conditions. The clinical evidence supporting the use of repository corticotropin (hereinafter referred to as corticotropin) has been weak, perhaps because its approval predated the modern review standards of the US Food and Drug Administration (FDA). OBJECTIVE: To characterize the clinical evidence supporting the use of corticotropin for its FDA-approved indications...

Aim: To determine whether clinicians evaluate American Academy of Neurology (AAN) quality metrics for patients with multiple sclerosis (MS) relapse and whether repository corticotropin injection (RCI) improves clinical and patient-reported outcomes associated with these metrics at 2 and 6 months after treatment. Methods: A multicenter, prospective, observational registry evaluating patients receiving RCI for MS relapse (N = 125) categorized data according to AAN quality metrics involving diagnosis, disability, fatigue, cognitive impairment, depression, and quality of life...

PURPOSE: Repository corticotropin injection (RCI; Acthar® Gel) is a naturally sourced mixture of adrenocorticotropic hormone analogs and other pituitary peptides that exerts anti-inflammatory and immunomodulatory properties via melanocortin receptors. RCI is approved as a short-term adjunctive therapy for rheumatoid arthritis (RA) and is typically used in patients with refractory RA. The objective of this study was to describe real-world outcomes of RA patients treated with RCI by retrospective analysis of an electronic medical records (EMR) database...

Background: Relapses are common among patients with multiple sclerosis (MS) despite treatment with disease-modifying therapies. Repository corticotropin injection (RCI, Acthar® Gel), plasmapheresis (PMP), and intravenous immunoglobulin (IVIg) are alternative therapies for MS relapse. There is a dearth of economic assessments of these therapies for the acute exacerbations of MS. This study estimated the cost-effectiveness of RCI compared to PMP or IVIg. Methods: A Markov state-transition model compared outcomes (costs, relapses, remission, and utilities) with RCI versus PMP or IVIg for the acute exacerbations in MS...

INTRODUCTION: Noninfectious keratitis is a painful corneal inflammation treated with topical cyclosporine and other immunosuppressants. Additional treatment options are needed for keratitis that does not improve with standard therapies. Repository corticotropin injection (RCI; Acthar® Gel) is approved to treat severe acute and chronic allergic and inflammatory processes involving the eye and its adnexa, including keratitis. This phase 4, multicenter, open-label study assessed the efficacy and safety of RCI for refractory severe noninfectious keratitis...

Repository corticotropin injection (RCI; Acthar Gel) is a naturally sourced complex mixture of adrenocorticotropic hormone (ACTH) analogs and other pituitary peptides. This phase 1, single-center, open-label, randomized parallel study directly compared the pharmacokinetics and pharmacodynamics of RCI and synthetic ACTH1-24 depot. Methylprednisolone was included to estimate the steroidogenic exposure of RCI and synthetic ACTH1-24 depot when used to treat nephrotic syndrome. A total of 48 healthy subjects aged 18 to 50 years were randomly assigned 1:1:1 to RCI (80 IU subcutaneously twice weekly on study days 1 and 4), synthetic ACTH1-24 depot (1 mg subcutaneously twice weekly on study days 1 and 4), or methylprednisolone (32 mg orally once daily on study days 1 through 6)...

INTRODUCTION: We conducted post hoc analyses of biomarker results from a multicenter, randomized, double-blind, placebo-controlled study of repository corticotropin injection (RCI; Acthar® Gel) in patients with persistently active systemic lupus erythematosus (SLE) despite treatment with moderate-dose glucocorticoids. METHODS: Adults with active SLE and moderate to severe rash and/or arthritis were enrolled in the primary study. Patients had active SLE despite treatment with stable glucocorticoids, antimalarials, and nonsteroidal anti-inflammatory drugs and/or immunosuppressants...

Purpose: To show whether subcutaneous repository corticotropin injection (RCI, Acthar® Gel, a repository corticotropin injection, can be an effective potential therapeutic agent for noninfectious retinal vasculitis. Methods: Patients with active retinal vasculitis were followed with serial ultra-wide-field fluorescein angiograms and treated with 80 units of subcutaneous repository corticotropin injection twice weekly. Results: Primary outcome of <mml:math xmlns:mml="https://www...

Introduction: Patients with active rheumatoid arthritis (RA) often have inadequately controlled symptoms and are unable to achieve remission or low disease activity despite aggressive treatment. This results in irreversible joint damage, adversely affecting patients' physical and social functioning. The objective was to estimate the cost-effectiveness of repository corticotropin injection (RCI) versus standard of care (SoC) in patients with active RA from the United States (US) payer and societal perspectives over two to three years...

INTRODUCTION: We assessed patient-reported outcomes from a multicenter, randomized, double-blind, placebo-controlled study of repository corticotropin injection (RCI; Acthar® Gel) in patients with persistently active systemic lupus erythematosus (SLE) despite treatment with moderate-dose glucocorticoids. METHODS: The trial enrolled adults with active SLE and moderate-to-severe rash and/or arthritis despite use of stable glucocorticoids (7.5 mg/day to 30 mg/day prednisone equivalent), antimalarials, and nonsteroidal anti-inflammatory drugs for ≥ 4 weeks and/or immunosuppressants for ≥ 8 weeks before screening...

Repository corticotropin injection (RCI), a complex mixture of adrenocorticotropic hormone (ACTH) analogs and other pituitary peptides, has been found to suppress key aspects of gene expression and cellular function in human B lymphocytes in vitro. The present studies reveal that neither individual POMC peptides (α-MSH, ACTH1-39 , ACTH1-24 , β-endorphin) nor other related pituitary neuropeptides are sufficient to elicit these effects, even though specific receptors capable of transmitting signals from these peptides are expressed by human B cells...

Studies were undertaken to evaluate the effectiveness of Acthar® Gel (repository corticotropin injection [RCI]) in the tetrodotoxin (TTX) model of early-life-induced epileptic spasms. Repository corticotropin injection (RCI) is widely used in the United States to treat infantile spasms. A major component of RCI is N25 deamidated ACTH. Additionally, we hoped to provide some insight into the possible role circulating corticosteroids play in spasm cessation by comparing the RCI dose-response relationships for spasm suppression to RCI-induced corticosterone release from the adrenal gland...

Background: Infantile spasms is a rare disease characterized by distinct seizures and hypsarrhythmia. Adrenocorticotropic hormone (ACTH) is available as a natural product (repository corticotropin injection, [RCI]; Acthar® Gel) and as synthetic analogs. RCI is a naturally-sourced complex mixture of purified ACTH analogs and other pituitary peptides approved by the United States Food and Drug Administration as a monotherapy for the treatment of infantile spasms. RCI is commonly used in the United States. Outside the United States, synthetic analogs of ACTH-synthetic ACTH1-24 (tetracosactide) and synthetic ACTH1-39 (corticotropin carboxymethyl-cellulose [CCMC])-are used...

INTRODUCTION: Repository corticotropin injection (RCI; Acthar Gel) is indicated to induce a diuresis or a remission of proteinuria in nephrotic syndrome (NS) without uremia of the idiopathic type or that due to lupus erythematosus. This study compares patient characteristics and measurable healthcare resource utilization (HCRU) between NS patients who received a prescription for RCI and then were either approved or denied treatment by their insurers. METHODS: A retrospective analysis of adults with NS from January 2015 to December 2018 was conducted using a de-identified open-source claims database...

Repository corticotropin injection (RCI) is indicated as adjunctive, short-term therapy in selected patients with RA. To characterize RCI users and identify predictors of RCI initiation in RA, we compared preindex characteristics, treatment patterns, comorbidities, healthcare resource utilization (HCRU), and costs for patients who had initiated RCI treatment (RCI cohort) versus patients with no RCI claims and ≥ 1 targeted synthetic or biologic disease-modifying antirheumatic drugs (ts/bDMARD) claim (non-RCI ts/bDMARD cohort)...

The pharmacokinetics (PK) and pharmacodynamics (PD) of clinically relevant doses of repository corticotropin injection (Acthar Gel) and synthetic ACTH1-24 depot have not been fully characterized. We compared the steroidogenic exposure of repository corticotropin injection and synthetic ACTH1-24 depot in healthy adults at therapeutic doses using data from 2 separate phase 1 studies. Subjects were randomly assigned to repository corticotropin injection 40 or 80 IU subcutaneously twice weekly or 80 IU subcutaneously 3 times weekly for 15 days or to daily synthetic ACTH1-24 depot doses of 0...

INTRODUCTION: Repository corticotropin injection (RCI; Acthar® Gel) is indicated for the treatment of acute exacerbations of multiple sclerosis (MS) in adults. Despite the well-documented clinical and economic benefits of RCI, many patients are denied use of the therapy by third-party payers. This study aims to understand the demographic and clinical characteristics of MS relapse patients who received a prescription for RCI from their physicians and then were either approved or denied treatment by their insurers...

PURPOSE: To compare the binding and agonistic activity of Acthar® Gel and synthetic melanocortin receptor (MCR) agonists and examine how the activity of select agonists affects the in vivo production of corticosterone. MATERIALS AND METHODS: In vitro binding was determined using concentration-dependent displacement of the ligand [125 I]Nle4 , D-Phe7 -α-melanocyte-stimulating hormone (α-MSH) on cells expressing MC1R, MC3R, MC4R, or MC5R. Functional activity was determined using a time-resolved fluorescence cyclic adenosine monophosphate (cAMP) assay in cells expressing MC1R, MC2R, MC3R, MC4R, or MC5R...
