Pharmacokinetics of Co-Suspension Delivery Technology Budesonide/Glycopyrronium/Formoterol Fumarate Dihydrate (BGF MDI) and Budesonide/Formoterol Fumarate Dihydrate (BFF MDI) Fixed-Dose Combinations Compared With an Active Control: A Phase 1, Randomized, Single-Dose, Crossover Study in Healthy Adults.

ABSTRACT: This randomized, phase 1, single-dose, crossover study (NCT02189304) compared the 12-hour pharmacokinetic (PK) and safety profiles of budesonide/glycopyrronium/formoterol fumarate dihydrate metered dose inhaler (BGF MDI) 320/14.4/10 ?g and budesonide/formoterol fumarate dihydrate (BFF) MDI 320/10 ?g (both formulated using innovative co-suspension delivery technology) to an active comparator (budesonide/formoterol fumarate dihydrate dry powder inhaler [BUD/FORM DPI] 320/9-?g delivered dose) in healthy adults. The potential for PK interaction between glycopyrronium and budesonide/formoterol within BGF MDI was assessed. Of 72 subjects randomized, 59 completed treatment. Systemic budesonide exposure (primary objective) based on area under the plasma drug concentration-time curve 0-12 hours (AUC0-12 ; % coefficient of variation) was 1598.38 (49.7), 1657.09 (50.4), and 1276.75 (70.4) pg·h/mL for BGF MDI, BFF MDI, and BUD/FORM DPI, respectively; and formoterol exposure (AUC0-12 [% coefficient of variation]) was 39.16 (45.9), 39.53 (40.5), and 23.24 (59.2) pg·h/mL, respectively. BGF MDI and BFF MDI were bioequivalent for budesonide and formoterol. All treatments were well tolerated. While systemic exposure to budesonide and formoterol was higher for BGF MDI and BFF MDI than for BUD/FORM DPI, there were no appreciable differences in the incidence of pharmacologically predictable adverse events. This, coupled with the absence of PK interactions, suggests the BGF MDI safety profile will be comparable to BUD/FORM DPI.

Project description:In patients with chronic obstructive pulmonary disease (COPD) who experience further exacerbations or symptoms, despite being prescribed dual long-acting muscarinic antagonist (LAMA)/long-acting β2-agonist (LABA) or inhaled corticosteroid (ICS)/LABA therapies, triple ICS/LAMA/LABA therapy is recommended. A previous network meta-analysis showed comparable efficacy of the ICS/LAMA/LABA, budesonide/glycopyrronium bromide/formoterol fumarate (BUD/GLY/FOR) 320/18/9.6 µg, to other fixed-dose and open combination triple therapies at 24 weeks in COPD. Subsequently, the ETHOS study was published, including data for 8509 patients, assessing the efficacy and safety of BUD/GLY/FOR over 52 weeks. This network meta-analysis (NMA) was conducted to compare the relative efficacy, safety, and tolerability of BUD/GLY/FOR 320/18/9.6 µg with other fixed-dose and open combination triple therapies in COPD over 52 weeks, including data from ETHOS. A systematic literature review was conducted to identify ≥ 10-week randomized controlled trials, including ≥ 1 fixed-dose or open combination triple-therapy arm, in patients with moderate-to-very severe COPD. The methodologic quality and risk of bias of included studies were assessed. Study results were combined using a three-level hierarchical Bayesian NMA model to assess efficacy and safety outcomes at or over 24 and 52 weeks. Meta-regression and sensitivity analyses were used to assess heterogeneity across studies. Nineteen studies (n = 37,741 patients) met the inclusion criteria of the review; 15 contributed to the base case network. LAMA/LABA dual combinations were combined as a single treatment group to create a connected network. Across all outcomes for exacerbations, lung function, symptoms, health-related quality of life, safety, and tolerability, the efficacy and safety of BUD/GLY/FOR were comparable to those of other triple ICS/LAMA/LABA fixed-dose (fluticasone furoate/umeclidinium/vilanterol and beclomethasone dipropionate/glycopyrronium bromide/formoterol fumarate) and open combinations at or over 24 and 52 weeks. Sensitivity analyses and meta-regression results for exacerbation outcomes were broadly in line with the base case NMA. In this NMA, BUD/GLY/FOR 320/18/9.6 μg showed comparable efficacy versus other ICS/LAMA/LABA fixed-dose or open combination therapies in terms of reducing exacerbation rates and improving lung function, symptoms and health-related quality of life in patients with moderate-to-very-severe COPD, in line with previously published meta-analysis results of triple combinations in COPD. The safety and tolerability profile of BUD/GLY/FOR was also found to be comparable to other triple combination therapies.

Project description:IntroductionTriple inhaled corticosteroid/long-acting muscarinic antagonist/long-acting β2-agonist (ICS/LAMA/LABA) combination therapy is recommended for patients with chronic obstructive pulmonary disease (COPD) who experience further exacerbations/symptoms on dual LAMA/LABA or ICS/LABA therapy. The relative efficacy of budesonide/glycopyrronium/formoterol fumarate metered dose inhaler 320/18/9.6 µg (BGF MDI) in COPD was compared with other ICS/LAMA/LABA fixed-dose and open combination therapies in a network meta-analysis (NMA).MethodsA 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 (FEV1), post-dose peak FEV1, and St. George's Respiratory Questionnaire (SGRQ) total score; proportion of SGRQ responders; and Transition Dyspnea Index focal score. Change from baseline in rescue medication use over weeks 12-24 was also analyzed. Meta-regression and sensitivity analyses were used to assess heterogeneity across studies.ResultsEighteen 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.ConclusionThis 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.

Project description:BackgroundChronic 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.MethodsWe 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.ResultsWe 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.ConclusionOur results collectively showed that BGF treatment could prevent PH in addition to ameliorating COPD progression via the inhibition of inflammatory NFκB signaling.

Project description:BackgroundJapanese guidelines recommend triple inhaled corticosteroid (ICS)/long-acting muscarinic antagonist (LAMA)/long-acting β2-agonist (LABA) therapy in patients with chronic obstructive pulmonary disease (COPD) and no concurrent asthma diagnosis who experience frequent exacerbations and have blood eosinophil (EOS) count ≥ 300 cells/mm3, and in patients with COPD and asthma with continuing/worsening symptoms despite receiving dual ICS/LABA therapy. These post-hoc analyses of the KRONOS study in patients with COPD and without an asthma diagnosis, examine the effects of fixed-dose triple therapy with budesonide/glycopyrronium/formoterol fumarate dihydrate (BGF) versus dual therapies on lung function and exacerbations based on blood EOS count - focusing on blood EOS count 100 to < 300 cells/mm3 - as a function of exacerbation history and COPD severity.MethodsIn KRONOS, patients were randomized to receive treatments that included BGF 320/14.4/10 µg, glycopyrronium/formoterol fumarate dihydrate (GFF) 14.4/10 µg, or budesonide/formoterol fumarate dihydrate (BFF) 320/10 µg via metered dose inhaler (two inhalations twice-daily for 24 weeks). These post-hoc analyses assessed changes from baseline in morning pre-dose trough forced expiratory volume in 1 s (FEV1) over 12-24 weeks and moderate or severe COPD exacerbations rates over 24 weeks. The KRONOS study was not prospectively powered for these subgroup analyses.ResultsAmong patients with blood EOS count 100 to < 300 cells/mm3, least squares mean treatment differences for lung function improvement favored BGF over BFF in patients without an exacerbation history in the past year and in patients with moderate and severe COPD, with observed differences ranging from 62 ml to 73 ml across populations. In this same blood EOS population, moderate or severe exacerbation rates were reduced for BGF relative to GFF by 56% in patients without an exacerbation history in the past year, by 47% in patients with moderate COPD, and by 50% in patients with severe COPD.ConclusionsThese post-hoc analyses of patients with moderate-to-very severe COPD from the KRONOS study seem to indicate clinicians may want to consider a step-up to triple therapy in patients with persistent/worsening symptoms with blood EOS count > 100 cells/mm3, even if disease severity is moderate and there is no recent history of exacerbations.Trial registrationClinicalTrials.gov registry number NCT02497001 (registration date, 13 July 2015).

Project description:BackgroundCombining two long-acting bronchodilators with complementary mechanisms of action may provide treatment benefits to patients with chronic obstructive pulmonary disease (COPD) that are greater than those derived from either treatment alone. The efficacy and safety of a fixed-dose combination (FDC) of aclidinium bromide, a long-acting muscarinic antagonist, and formoterol fumarate, a long-acting β2-agonist, in patients with moderate to severe COPD are presented.MethodsIn this 24-week double-blind study, 1692 patients with stable COPD were equally randomized to twice-daily treatment with FDC aclidinium 400 μg/formoterol 12 μg (ACL400/FOR12 FDC), FDC aclidinium 400 μg/formoterol 6 μg (ACL400/FOR6 FDC), aclidinium 400 μg, formoterol 12 μg, or placebo administered by a multidose dry powder inhaler (Genuair®/Pressair®)*. Coprimary endpoints were change from baseline to week 24 in 1-hour morning postdose FEV1 (FDCs versus aclidinium) and change from baseline to week 24 in morning predose (trough) FEV1 (FDCs versus formoterol). Secondary endpoints were change from baseline in St. George's Respiratory Questionnaire (SGRQ) total score and improvement in Transition Dyspnea Index (TDI) focal score at week 24. Safety and tolerability were also assessed.ResultsAt study end, improvements from baseline in 1-hour postdose FEV1 were significantly greater in patients treated with ACL400/FOR12 FDC or ACL400/FOR6 FDC compared with aclidinium (108 mL and 87 mL, respectively; p < 0.0001). Improvements in trough FEV1 were significantly greater in patients treated with ACL400/FOR12 FDC versus formoterol (45 mL; p = 0.0102), a numerical improvement of 26 mL in trough FEV1 over formoterol was observed with ACL400/FOR6 FDC. Significant improvements in both SGRQ total and TDI focal scores were observed in the ACL400/FOR12 FDC group at study end (p < 0.0001), with differences over placebo exceeding the minimal clinically important difference of ≥4 points and ≥1 unit, respectively. All treatments were well tolerated, with safety profiles of the FDCs similar to those of the monotherapies.ConclusionsTreatment with twice-daily aclidinium 400 μg/formoterol 12 μg FDC provided rapid and sustained bronchodilation that was greater than either monotherapy; clinically significant improvements in dyspnea and health status were evident compared with placebo. Aclidinium/formoterol FDC may be an effective and well tolerated new treatment option for patients with COPD.Trial registrationClinicaltrials.gov NCT01437397.
