Results From a Phase 4, Multicenter, Randomized, Double-Blind, Placebo-Controlled Study of Repository Corticotropin Injection for the Treatment of Pulmonary Sarcoidosis.

INTRODUCTION: Long-term treatment of pulmonary sarcoidosis with glucocorticoids has been associated with toxicity and other adverse events, highlighting the need for alternative therapies. The goal of this study was to evaluate the efficacy and safety of repository corticotropin injection (RCI, Acthar® Gel) in patients with pulmonary sarcoidosis and to validate endpoints for use in future clinical trials. METHODS: In this multicenter, randomized, placebo-controlled trial, subjects received subcutaneous RCI (80 U) twice weekly or matching placebo through 24 weeks in a double-blind treatment phase, followed by an optional 24-week open-label extension. Efficacy was measured by glucocorticoid tapering, pulmonary function tests, chest imaging, patient-reported outcomes, and a novel sarcoidosis treatment score (STS). Safety was assessed by adverse events, physical examinations, vital signs, clinical laboratory abnormalities, and imaging. The study was terminated early due to low enrollment caused by the COVID-19 pandemic, thereby precluding statistical analysis. RESULTS: Fifty-five subjects were randomized to receive either RCI (n = 27) or placebo (n = 28). Mean STS at week 24 showed greater improvement with RCI (1.4) compared with placebo (0.7). At week 48, those who remained on RCI had an STS of 1.8 compared with 0.9 in those who switched from placebo to RCI. More subjects in the RCI group discontinued glucocorticoids at week 24 compared to the placebo group. Glucocorticoid discontinuation was comparable at week 48 for those who switched from placebo to RCI and those who continued RCI. Similar trends in favor of RCI over placebo were observed with the other efficacy endpoints. No new or unexpected safety signals were identified. CONCLUSIONS: RCI was safe and well tolerated, with trends in efficacy data suggesting greater improvement with RCI compared to placebo in patients receiving standard-of-care therapy for pulmonary sarcoidosis. The study also provided validation of efficacy endpoints that may be used in larger trials for pulmonary sarcoidosis. TRIAL REGISTRATION: ClinicalTrials.gov identifier: NCT03320070.

Pulmonary sarcoidosis is a disease characterized by inflammation of the lungs. Standard treatments include glucocorticoids, which may have harmful side effects. This clinical trial investigated whether repository corticotropin injection (RCI, Acthar^® Gel) was safe and effective in patients who were already taking glucocorticoids to treat pulmonary sarcoidosis. Patients were randomly assigned to be in one of two treatment groups: RCI or placebo. In the first 24 weeks of the study, 27 patients were injected with RCI twice weekly, while 28 patients were injected with an inactive substance (placebo). Forty-seven patients continued into an optional phase of the study for an additional 24 weeks in which all patients received RCI twice weekly. A sarcoidosis treatment score and assessments of lung health, general health, and fatigue were used to determine whether RCI was effective. These assessments showed greater improvements with RCI compared to placebo. Patients who switched from placebo to RCI showed similar improvements to those who remained on RCI throughout the entire study. Patients receiving RCI were able to discontinue their use of glucocorticoids more quickly than those taking placebo, thus helping them to avoid the harmful side effects of the glucocorticoids. Side effects for RCI were mostly mild or moderate, and no new or unexpected safety concerns for RCI were seen throughout the study.

Results from a multicenter, randomized, double-blind, placebo-controlled study of repository corticotropin injection for multiple sclerosis relapse that did not adequately respond to corticosteroids.

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. This was a multicenter, double-blind, placebo-controlled study. Nonresponders to high-dose corticosteroids were randomized to receive RCI (80 U) or placebo daily for 14 days. Assessments included improvements on the Expanded Disability Status Scale (EDSS), Multiple Sclerosis Impact Scale (MSIS-29), Clinical Global Impression of Improvement (CGI-I), and adverse events (AEs). RESULTS: Eighteen patients received RCI, and 17 received placebo. A greater proportion of EDSS responders was observed in the RCI group at Day 7, 21, and 42 compared with the placebo group. Qualitative CGI-I showed that more patients receiving RCI were much improved or very much improved than with placebo. No meaningful differences were observed between treatment groups for MSIS-29. No serious AEs or deaths were reported. CONCLUSION: RCI is safe and effective for MS relapse patients who do not respond to high-dose corticosteroids.

Use of inhaled nitric oxide in preterm vs term/near-term neonates with pulmonary hypertension: results of the PaTTerN registry study.

OBJECTIVE: To evaluate inhaled nitric oxide (iNO) in preterm (PT) vs term/near-term (TNT) neonates with hypoxic respiratory failure (HRF) and pulmonary hypertension (PH) in an observational registry (PaTTerN). STUDY DESIGN: Non-inferiority study comparing PT neonates of GA ≥ 27 to <34 weeks vs TNT neonates of GA ≥ 34 to ≤40 weeks with HRF associated with PH, who received iNO for 24-96 h during the first 0-7 days after birth. Primary endpoint: Achieving ≥25% decrease in oxygenation index/surrogate oxygenation index during iNO treatment. RESULTS: Of 140 neonates (PT, n = 55; TNT, n = 85), the primary endpoint was achieved in 50 (90.9%) PT vs 75 (88.2%) TNT neonates (difference [95% CI]: 0.027 [-0.033, 0.087]); PT neonates achieved non-inferiority interval, and the study was stopped early based on prespecified criteria. CONCLUSIONS: Use of iNO for improving oxygenation in PT neonates with HRF associated with PH is at least as effective as in TNT neonates.

Tapentadol for the Treatment of Moderate-to-Severe Acute Pain in Children Under the Age of Two Years.

BACKGROUND: Pharmacokinetics (PK), efficacy, and safety of the opioid analgesic tapentadol in the treatment of moderate-to-severe acute pain have so far not been investigated in pediatric patients <2 years of age. PATIENTS AND METHODS: Two multicenter, open-label trials assessed the pharmacokinetic profile, safety, tolerability, and efficacy of single doses of tapentadol oral solution (OS; NCT02221674; n=19) or intravenous infusion (IV, EudraCT 2014-002259-24; n=38) in children from birth to <2 years of age. Of these, 8 preterm neonates were included in the IV trial. A third randomized, double-blind, placebo-controlled trial (NCT02081391) investigated the efficacy and safety of multiple tapentadol OS doses in patients from birth to <2 years (placebo n=4, tapentadol n=11) using an immediate rescue trial design. Patients in all three trials underwent surgery that, in the investigator's opinion, reliably produced moderate-to-severe pain requiring opioid treatment. RESULTS: Administration of single tapentadol doses resulted in tapentadol serum concentrations within the targeted range known to be safe and efficacious in adults and compared well to the range observed for children aged 2 to <18 years. Pain intensity already improved 15 min after administration. In the multiple dose trial, amounts of supplemental opioid analgesic medication within the first 24 h after start of trial medication were low (placebo 0.02 mg/kg, tapentadol 0.05 mg/kg). All patients stopped treatment with the trial medication because opioid analgesics were no longer required. Treatment-emergent adverse events occurred in 42.1% (tapentadol OS single dose), 28.9% (tapentadol IV), and 75% of placebo and 54.5% of tapentadol patients (tapentadol OS multiple doses), none of them serious. CONCLUSION: Tapentadol showed a favorable PK and safety profile in children <2 years of age. Multiple tapentadol OS dosing is efficacious and generally well tolerated in children ≥2 years and might also be a useful treatment option for children <2 years in need of strong analgesics.

Pharmacokinetics, safety, and efficacy of tapentadol oral solution for treating moderate to severe pain in pediatric patients.

Background: This trial is part of the global pediatric clinical development program investigating the administration of the strong analgesic tapentadol in children and adolescents. Patients and methods: The single site, open-label phase 2 trial evaluated the pharmacokinetic profile of tapentadol and its major metabolite, tapentadol-O-glucuronide, as well as safety and tolerability and efficacy of a single dose of tapentadol oral solution (1 mg/kg) in patients (2 to <18 years) undergoing dental, ear, nose, or throat surgery. Blood sampling and pain intensity measurements were conducted using age-appropriate schedules and rating scales, respectively. Adverse events were monitored throughout the trial. Results: Sixty-six patients were treated. They were stratified by age: Group 1 (12 to <18 years), n=21; Group 2 (6 to <12 years), n=28; and Groups 3 (3 to <6 years) and 4 (2 to <3 years), n=17. Serum tapentadol concentrations observed in these pediatric patients were within the range observed in adults after administration of a single tapentadol immediate-release dose (50-100 mg), whereas those of the metabolite tapentadol-O-glucuronide were within the same range or lower than in adults who received comparable single doses of tapentadol. Pain intensity improved over time across all age groups. The most common treatment-emergent adverse events were nausea (24.2%), vomiting (16.7%), dizziness (9.1%), and headache (6.1%). Conclusion: A single dose of tapentadol oral solution (1 mg/kg) administered to pediatric patients (2 to <18 years) resulted in serum tapentadol concentrations within the targeted range shown to be safe and efficacious in adults. Tapentadol demonstrated good tolerability and safety; within the limitations of the trial design, improvements in postsurgical pain intensity were observed across the age groups. Tapentadol may provide a new treatment option in the management of moderate to severe pediatric pain.
