Triple therapy to prevent exacerbations from chronic obstructive pulmonary disease (COPD) is associated with improved health compared to single and dual-agent therapy in some populations. This study assessed the benefits of prompt administration of budesonide/glycopyrrolate/formoterol fumarate (BGF) following a COPD exacerbation.
EROS was a retrospective analysis of people with COPD using the MORE2 Registry®. Inclusion required ≥1 severe, ≥2 moderate, or ≥1 moderate exacerbation while on other maintenance treatment. Within 12 months following the index exacerbation, ≥1 pharmacy claim for BGF was required. Primary outcomes were the rate of COPD exacerbations and healthcare costs for those that received BGF promptly (within 30 days of index exacerbation) versus delayed (31-180 days) and very delayed (181-365 days). The effect of each 30-day delay in initiation of BGF was estimated using a multivariable negative binomial regression model.
2409 patients were identified: 434 prompt, 1187 delayed, and 788 very delayed. The rate (95% CI) of total exacerbations post-index increased as time to BGF initiation increased: prompt 1.52 (1.39-1.66); delayed 2.00 (1.92-2.09); and very delayed 2.30 (2.20-2.40). Adjusting for patient characteristics, each 30-day delay in receiving BGF was associated with a 5% increase in the average number of subsequent exacerbations (rate ratio, 95% CI: 1.05, 1.01-1.08; p<0.05). Prompt initiation of BGF was also associated with lower post-index annualized COPD-related costs ($5002 for prompt vs $7639 and $8724 for the delayed and very delayed groups, respectively).
Following a COPD exacerbation, promptly initiating BGF was associated with a reduction in subsequent exacerbations and reduced healthcare utilization and costs.

BACKGROUND: The climate crisis poses an immediate threat to human health and well-being, demanding urgent adaptions across sectors, including healthcare. The development of pressurized metered dose inhalers (MDIs) with greater sensitivity to the climate emergency using novel propellants with lower global warming potentials (GWPs), but comparable pharmacokinetic (PK) parameters to currently marketed MDIs, is a vital step toward reducing the impact of healthcare for respiratory disorders on climate change. This study evaluated the relative bioavailabilities of the individual components of a fixed-dose combination of budesonide/glycopyrrolate/formoterol fumarate (BGF) 160/9/4.8 μg per actuation between three different propellant formulations.
METHODS: Healthy male participants (aged 18-60 years) were randomized into a single-blind, three-period, single-dose, single-center, crossover study (NCT04600505). The PK and safety and tolerability profiles of BGF MDI formulated with two novel propellants with low GWP (hydrofluoroolefin-1234ze [HFO]; hydrofluorocarbon-152a [HFC]) were compared with BGF MDI formulated with the propellant used in the currently marketed reference product (hydrofluoroalkane-134a [HFA]). The study included a screening period, three treatment periods (with 3- to 7-day washout periods between each dose), and a follow-up. The primary PK parameters assessed were maximum observed plasma concentration (Cmax), area under the plasma concentration curve (AUC) from time zero extrapolated to infinity (AUCinf), and AUC from time zero to the time of the last quantifiable analyte concentration (AUClast). The study was not powered to statistically demonstrate bioequivalence.
RESULTS: Forty-seven participants completed the study, and 24 participants were evaluable for PK assessments. Systemic exposure, based on geometric mean ratios (90% confidence interval), to each BGF component from the test propellants delivered in a standard MDI was comparable with the reference propellant for AUClast (HFO vs. HFA: budesonide, 107.30 [94.53, 121.90]; glycopyrrolate, 106.10 [86.18, 130.60]; formoterol, 98.13 [86.44, 111.40]; HFC vs. HFA: budesonide, 98.80 [84.59, 115.40]; glycopyrrolate, 99.71 [80.84, 123.00]; formoterol, 107.00 [88.82, 128.90]); AUCinf (where evaluable) and Cmax followed the same trend. There were no serious adverse events or adverse events leading to treatment discontinuation. No new safety signals were observed.
CONCLUSIONS: Systemic BGF component exposure was similar for both test propellants (HFO and HFC) compared with the HFA reference propellant, with an acceptable safety profile in the studied population. Therefore, both novel low GWP propellants show strong potential as candidates for development of MDIs with greater sensitivity to the climate crisis, a vital step toward ameliorating the detrimental impact of healthcare on the environment. Further investigation in larger studies is warranted.

UNASSIGNED: Chronic obstructive pulmonary disease (COPD) is a leading cause of death worldwide. While two approved fixed-dose inhaled corticosteroid/long-acting muscarinic antagonist (LAMA)/long-acting β2-agonist (LABA) triple therapies reduce all-cause mortality (ACM) versus dual LAMA/LABA therapy in patients with COPD, head-to-head studies have not compared the effects of these therapies on ACM. We compared ACM in adults with moderate-to-very severe COPD receiving budesonide/glycopyrrolate/formoterol fumarate (BGF) in ETHOS versus fluticasone furoate/umeclidinium/vilanterol (FF/UMEC/VI) in IMPACT using a matching-adjusted indirect comparison (MAIC).
UNASSIGNED: A systematic literature review identified two studies (ETHOS [NCT02465567]; IMPACT [NCT02164513]) of ≥52 weeks reporting ACM as an efficacy endpoint in patients receiving triple therapy. As ETHOS and IMPACT lack a common comparator, an unanchored MAIC compared ACM between licensed doses of BGF (320/18/9.6 μg) from ETHOS and FF/UMEC/VI (100/62.5/25 μg) from IMPACT in patients with moderate-to-very severe COPD. Using on- and off-treatment data from the final retrieved datasets of the intention-to-treat populations, BGF data were adjusted according to aggregate FF/UMEC/VI data using 11 baseline covariates; a supplementary unadjusted indirect treatment comparison was also conducted. P-values for these post-hoc analyses are not adjusted for Type I error.
UNASSIGNED: ACM over 52 weeks was statistically significantly reduced by 39% for BGF versus FF/UMEC/VI in the MAIC (hazard ratio [HR] [95% CI]: 0.61 [0.38, 0.95], p = 0.030) and unadjusted analysis (HR [95% CI]: 0.61 [0.41, 0.92], p = 0.019).
UNASSIGNED: In this MAIC, which adjusted for population heterogeneity between ETHOS and IMPACT, ACM was significantly reduced with BGF versus FF/UMEC/VI in patients with moderate-to-very severe COPD.
Chronic obstructive pulmonary disease (known as COPD) is a leading cause of death worldwide, being responsible for over 3 million deaths in 2019. People living with COPD are more likely to die. Importantly, a sudden worsening of COPD symptoms (known as an exacerbation) is associated with a higher chance of death from heart-related and breathing-related problems. Therefore, reducing risk of death is an important treatment goal for COPD. Of the three medications approved for treating COPD that combine three drugs in a single-inhaler device, there are two—referred to generically as budesonide/glycopyrrolate/formoterol fumarate (BGF) and fluticasone furoate/umeclidinium/vilanterol (FF/UMEC/VI)—that can reduce the risk of death in people living with COPD compared with treatments that combine two drugs. However, no studies have directly compared the risk of death in people living with COPD treated with these medicines. We compared the risk of death in people living with moderate-to-very severe COPD who received either BGF during a clinical trial called ETHOS or FF/UMEC/VI during a clinical trial called IMPACT. To make this comparison, we used a method called “matching-adjusted indirect comparison”, which used specific features (such as sex, breathing difficulty, and whether they were current smokers) to match patients from the two studies to ensure similar groups were examined. Our analysis showed a 39% decrease in the chance of death in patients who received BGF compared with patients who received FF/UMEC/VI. This finding may be important for doctors to improve patient health and reduce the risk of death in people living with COPD.

Awareness of the management of coronavirus disease 2019 (COVID-19) and airway diseases can effectively help clinical physician during the coronavirus pandemic. Herein, we elucidated a COVID-19 case coexisting with severe asthma. Budesonide/glycopyrrolate/formoterol fumarate (BGF) was used as sequential medicine to systemic glucocorticoids for his persisted symptoms related to bronchospasms. Our case suggests patients with long-term airway diseases like asthma probably attribute their symptoms to COVID-19 instead of primary diseases, which make it more difficult in the symptom control. BGF is able to be an effective and convenient choice as sequential medicine to systemic glucocorticoids in some refractory asthmatic patients complicated with COVID-19.
