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:INTRODUCTION:Triple inhaled corticosteroid/long-acting muscarinic antagonist/long-acting ?2-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). METHODS: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 (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. RESULTS: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. CONCLUSION: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.

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: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: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.

Project description:BackgroundFor patients with chronic obstructive pulmonary disease (COPD), greater improvements in lung function have been demonstrated for triple versus dual inhaled therapies in traditional spirometry studies. This study was the first to use functional respiratory imaging (FRI), known for increased sensitivity to airway changes versus spirometry, to assess the effect of the inhaled corticosteroid (ICS) component (budesonide) on lung function in patients with moderate-to-severe COPD and a blood eosinophil count > 150 cells/mm3.MethodsPatients in this Phase IIIb (NCT03836677), randomized, double-blind, crossover study received twice-daily budesonide/glycopyrrolate/formoterol fumarate (BGF) 320/18/9.6 μg fixed-dose triple therapy and glycopyrrolate/formoterol fumarate (GFF) 18/9.6 μg fixed-dose dual therapy over 4 weeks, each delivered via a single metered dose Aerosphere inhaler. Primary endpoints were the improvements from baseline for each treatment in specific (i.e. corrected for lobar volume) image-based airway volume (siVaw) and resistance (siRaw) measured via FRI taken at total lung capacity (Day 29). Secondary outcomes included spirometry and body plethysmography. Adverse events were monitored throughout the study.ResultsA total of 23 patients were randomized and included in the intent-to-treat analysis (mean age 64.9 years, 78.3% males, 43.5% current smokers, mean predicted post-bronchodilator forced expiratory volume in 1 s [FEV1] 63.6%). BGF and GFF both statistically significantly increased siVaw from baseline at Day 29 (geometric mean ratio [GM], 95% confidence interval [CI]: 1.72 [1.38, 2.13] and 1.53 [1.28, 1.83], respectively, both p < 0.0001), with a greater increase observed for BGF versus GFF (GM, 95% CI 1.09 [1.03, 1.16], p = 0.0061). Statistically significant reductions in siRaw were also observed with both BGF and GFF (GM, 95% CI 0.50 [0.39, 0.63] and 0.52 [0.40, 0.67], respectively, both p < 0.0001). Additionally, significant improvements from baseline in post-dose FEV1 were observed with BGF and GFF (mean 346 mL, p = 0.0003 and 273 mL, p = 0.0004, respectively). Safety findings were consistent with the known profiles of BGF and GFF.ConclusionsAs observed using FRI, triple therapy with BGF resulted in greater increases in airway volume, and reductions in airway resistance versus long-acting muscarinic antagonist/long-acting β2-agonist (LAMA/LABA) dual therapy with GFF, reflecting the ICS component's contribution in patients with moderate-to-severe COPD.Trial registration ClinicalTrials.gov, NCT03836677.

Project description:Purpose:This study investigated the efficacy, safety, and pharmacokinetics of the inhaled corticosteroid/long-acting ?2-agonist fixed-dose combination budesonide/formoterol fumarate (BFF) metered dose inhaler (MDI), compared with the monocomponents budesonide (BD) MDI and formoterol fumarate (FF) MDI, in patients with moderate-to-severe COPD. Materials and methods:In this Phase IIb, randomized, double-blind, four-period, five-treatment, incomplete-block, crossover study (NCT02196077), all patients received BFF MDI 320/9.6 ?g and FF MDI 9.6 ?g, and two of either BFF MDI 160/9.6 ?g, BFF MDI 80/9.6 ?g, or BD MDI 320 ?g twice daily for 28 days. The primary efficacy endpoint was forced expiratory volume in 1 second area under the curve from 0 to 12 hours on Day 29. Secondary efficacy endpoints included additional lung function assessments, and evaluation of dyspnea and rescue medication use. Safety was monitored throughout. The systemic exposure to budesonide and formoterol was assessed on Day 29. Results:Overall, 180 patients were randomized. For forced expiratory volume in 1 second area under the curve from 0 to 12 hours on Day 29, all BFF MDI doses showed significant improvements versus BD MDI 320 ?g (least squares mean differences 186-221 mL; all p<0.0001), and BFF MDI 320/9.6 ?g demonstrated a significant improvement versus FF MDI 9.6 ?g (least squares mean difference 56 mL; p=0.0013). Furthermore, all BFF MDI doses showed significant improvements versus BD MDI 320 ?g for all lung function, dyspnea, and rescue medication use secondary efficacy endpoints. All BFF MDI doses were well tolerated, and the safety profile was not substantially different from the monocomponents. There was no evidence of clinically meaningful pharmacokinetic interactions when budesonide and formoterol were formulated together in BFF MDI. Conclusion:The findings presented here confirm that BFF MDI 320/9.6 ?g is an appropriate dose to take forward into Phase III studies in patients with COPD.
