fumarates and Pulmonary-Disease--Chronic-Obstructive

Chronic obstructive pulmonary disease (COPD) is a highly prevalent chronic respiratory disease with considerable clinical and socioeconomic impact. Budesonide/glycopyrrolate/formoterol fumarate (BGF) is a newly approved pharmacotherapy for COPD in China that has been shown to improve lung function and reduce the risk of exacerbations, but the cost-effectiveness of BGF remains unknown. The objective of this study was to evaluate the cost-effectiveness of BGF in patients with moderate to very severe COPD from a Chinese healthcare system perspective.. A semi-Markov model was developed to compare the costs and benefit of treatment with BGF versus a composite comparator of long-acting muscarinic antagonist/long-acting β2-agonist (LAMA/LABA) therapies. Clinical inputs for BGF and the composite comparator were based on the KRONOS study (NCT02497001) and a network meta-analysis. Cost inputs were derived from published literature and Chinese government documents, supplemented by expert opinion where necessary. Health-related quality-of-life inputs were also obtained based on the KRONOS study. Lifetime costs, number of exacerbations, quality-adjusted life-years (QALYs), and incremental cost-effectiveness ratios (ICERs) were estimated. Costs were measured in 2020 Chinese Yuan (CN¥) and converted into US dollars (US$). Scenario analyses and sensitivity analyses were conducted.. Over the lifetime horizon, BGF treatment led to fewer moderate and severe exacerbations (4.01 and 0.87, respectively) versus the composite comparator (8.42 and 2.04, respectively), with a base-case ICER of CN¥13,685.94 (US$1983.47) per QALY gained. Scenario analyses considering different population and utilities resulted in ICERs ranging from dominant to CN¥13,673.91 (US$1981.73). Extensive sensitivity analyses indicated robust base-case results since all analyses yielded ICERs below the conservative cost-effectiveness threshold of one times the Chinese per capita gross domestic product (CN¥72,447.00 [US$10,499.57], 2020).. Triple therapy with BGF was predicted to improve outcomes and be a cost-effective treatment option compared with LAMA/LABA therapies for patients with moderate to very severe COPD in China.

To review current evidence on the use of a fixed-dose combination (FDC) of budesonide/glycopyrrolate/formoterol fumarate (BGFF) triple therapy delivered via metered dose inhaler (MDI) in patients with chronic obstructive pulmonary disease (COPD) and offer clinical practice insights.. We used PubMed to conduct the literature search from 1946 through June 30, 2021, using budesonide, glycopyrrolate or glycopyrronium, and formoterol.. We included clinical trials in patients with COPD along with pharmacokinetic or pharmacodynamic studies.. In all, 19 citations were included. BGFF MDI reduces the risk of exacerbations regardless of exacerbation history compared with dual bronchodilators or inhaled corticosteroid/long-acting β-agonist. Rescue inhaler use decreased, and patient-reported outcomes of symptoms and well-being improved with triple therapy. Mortality was decreased with the higher-dose BGFF MDI in comparison to dual bronchodilator therapy. Dysphonia and candidiasis were more common with BGFF MDI compared with dual bronchodilators, as was pneumonia.. BGFF MDI is the second FDC triple therapy approved for COPD treatment. BGFF MDI improves important patient outcomes in COPD, including exacerbation risk. The unique co-suspension technology allows delivery of 3 active ingredients in 1 inhaler, a potential benefit to overcome adherence and technique-related barriers. These benefits must be gently weighed against the increased risk of pneumonia.. The findings from phase 3 trials support the efficacy and safety of triple therapy in COPD. Future studies are needed to confirm potential mortality benefit and the role of triple therapy in patients without an exacerbation history.

A systematic literature review was conducted to identify randomized controlled trials of at least 10-week duration, including at least one fixed-dose or open combination triple therapy arm, in patients with moderate to very severe COPD. Studies were assessed for methodological quality and risk of bias. A three-level hierarchical Bayesian NMA model was used to determine the exacerbation rate per patient per year as well as the following outcomes at week 24: changes from baseline in pre-dose trough forced expiratory volume in 1 s (FEV. Eighteen studies (n = 29,232 patients) contributed to the NMA. ICS/LABA dual combinations were combined as a single treatment group to create a connected network. Across all outcomes, there were no statistically significant differences between BGF MDI and other triple ICS/LAMA/LABA fixed-dose (fluticasone furoate/umeclidinium/vilanterol and beclomethasone dipropionate/glycopyrronium/formoterol fumarate) and open combinations with data available within the network. Results from sensitivity analyses and meta-regression were consistent with the base-case scenario.. This NMA suggested that BGF MDI has comparable efficacy to other ICS/LAMA/LABA fixed-dose and open triple combination therapies in reducing exacerbations and improving lung function and symptoms in patients with moderate to very severe COPD. Further research is warranted as additional evidence regarding triple therapies, especially fixed-dose combinations, becomes available.

The Phase III KRONOS study (NCT02497001) found the fixed-dose combination triple therapy budesonide/glycopyrrolate/formoterol fumarate metered dose inhaler (BGF MDI) to be efficacious and well tolerated versus corresponding dual therapies in patients with moderate-to-very severe COPD from North America, China and Japan. However, pharmacokinetic (PK) studies of other drugs have shown that ethnic factors (e.g. genetic factors affecting drug metabolism) can affect the bioavailability of drugs which may impact upon efficacy and safety outcomes.. The analyses included data from 64 Chinese, 31 Japanese and 169 Western subjects. Overall, PK properties following single or repeated dosing of BGF MDI were similar across Chinese, Japanese and Western subjects. After single dosing at either dose level, AUC. Overall, these analyses suggest no appreciable ethnic differences in the PK of BGF MDI across Chinese, Japanese and Western healthy subjects.

Chronic obstructive pulmonary disease (COPD) is a health problem that results in death, commonly due to the development of pulmonary hypertension (PH). Here, by utilizing a mouse model of intratracheal elastase-induced emphysema that presents three different phases of COPD, we sought to observe whether budesonide/glycopyrronium/formoterol fumarate (BGF) triple therapy could prevent COPD-PH in addition to ameliorating COPD progression.. We utilized intratracheal elastase-induced emphysema mouse model and performed experiments in three phases illustrating COPD progression: inflammatory (1 day post-elastase), emphysema (3 weeks post-elastase) and PH (4 weeks post-elastase), while treatments of BGF and controls (vehicle, one-drug, and two-drug combinations) were started in prior to elastase instillation (inflammatory phase), at day 7 (emphysema), or at day 14 (PH phase). Phenotype analyses were performed in each phase. In vitro, A549 cells or isolated mouse lung endothelial cells (MLEC) were treated with TNFα with/without BGF treatment to analyze NFκB signaling and cytokine expression changes.. We observed significant reductions in the proinflammatory phenotype observed in the lungs and bronchoalveolar lavage fluid (BALF) 1 day after elastase administration in mice treated with BGF compared with that in mice administered elastase alone (BALF neutrophil percentage, p = 0.0011 for PBS/Vehicle vs. PBS/Elastase, p = 0.0161 for PBS/Elastase vs. BGF). In contrast, only BGF treatment significantly ameliorated the elastase-induced emphysematous lung structure and desaturation after three weeks of elastase instillation (mean linear intercept, p = 0.0156 for PBS/Vehicle vs. PBS/Elastase, p = 0.0274 for PBS/Elastase vs. BGF). Furthermore, BGF treatment prevented COPD-PH development, as shown by improvements in the hemodynamic and histological phenotypes four weeks after elastase treatment (right ventricular systolic pressure, p = 0.0062 for PBS/Vehicle vs. PBS/Elastase, p = 0.027 for PBS/Elastase vs. BGF). Molecularly, BGF acts by inhibiting NFκB-p65 phosphorylation and subsequently decreasing the mRNA expression of proinflammatory cytokines in both alveolar epithelial and pulmonary endothelial cells.. Our results collectively showed that BGF treatment could prevent PH in addition to ameliorating COPD progression via the inhibition of inflammatory NFκB signaling.

To evaluate the cost-effectiveness of Budesonide/Glycopyrronium/Formoterol (BUD/GLY/FOR) versus LAMA/LABA and ICS/LABA, respectively, in patients with moderate to severe COPD, from the Spanish National Healthcare System (NHS) perspective.. A lifetime Markov model with monthly cycle length was developed with baseline and treatment effect data from ETHOS clinical trial, together with utility values from literature and Spanish healthcare resource costs (€, 2021). A 3% annual discount rate was used for costs and benefits. The model comprised ten health states: nine forced expiratory volume in 1 second (FEV1)-related, which were divided by three levels of severity: moderate (FEV1 ≥50% and <80%); severe (FEV1 ≥30% and <50%) and very severe (FEV1 <30%) and a death state. Each FEV1-health state was divided into no exacerbation, moderate exacerbation, and severe exacerbations. An expert panel validated data and assumptions. Outcomes were measured as incremental cost per exacerbation avoided, per life year (LY) gained, and per quality-adjusted life-year (QALY) gained (ICUR). One-way (OWSA), scenario, and probabilistic sensitivity analyses (PSA) were performed.. According to this cost-effectiveness analysis based on a Markov model, BUD/GLY/FOR was associated with a lower totals exacerbation per patient (12.80) compared to LAMA/LABA (13.36) and ICS/LABA (13.23) and higher LYs (10.32 vs 10.14 and 10.06, respectively) and QALYs (7.55 vs 7.41 and 7.32, respectively). The incremental costs were €850.95, and €2422.26, respectively, per exacerbation avoided, €2733.38 and €4111.15, respectively, per LY gained and €3461.19 and €4545.24 per QALY gained. OWSA showed that the model was most sensitive to the costs of treatments following discontinuation, but the ICUR remained below the cost-effectiveness threshold of €25,000 per QALY gained. In the PSA, the probability of BUD/GLY/FOR being cost-effective was 91.32% vs LAMA/LABA and 99.29% vs ICS/LABA.. BUD/GLY/FOR is a cost-effective treatment strategy for Spanish NHS patients with COPD compared to dual therapies.
