Abstract Background The single-inhaler triple combination of beclometasone dipropionate, formoterol fumarate, and glycopyrronium (BDP/FF/G) is available for maintenance therapy of chronic obstructive pulmonary disease (COPD). Cardinal features of COPD are lung hyperinflation and reduced exercise capacity. TRIFORCE aimed to evaluate the effect of BDP/FF/G on lung hyperinflation and exercise capacity in patients with COPD. Methods This double-blind, randomised, active- and placebo-controlled, crossover study recruited adults with COPD aged ≥ 40 years, who were hyperinflated and symptomatic, and were receiving mono- or dual inhaled maintenance COPD therapy. In the three treatment periods, patients were randomised to receive BDP/FF/G, BDP/FF, or placebo, each for 3 weeks, with a 7–10-day washout between treatment periods. Assessments included slow inspiratory spirometry (for resting inspiratory capacity [IC]) and constant work-rate cycle ergometry (for dynamic IC and exercise endurance time). The primary objective was to compare BDP/FF/G and BDP/FF vs. placebo for resting IC at Week 3. Key secondary objectives were to compare BDP/FF/G and BDP/FF vs. placebo for dynamic IC and exercise endurance time during constant work rate cycle ergometry at Week 3. Results Of 106 patients randomised, 95 completed the study. Resting IC adjusted mean differences vs. placebo were 315 and 223 mL for BDP/FF/G and BDP/FF, respectively (p

Abstract Background Chronic obstructive pulmonary disease (COPD) is a chronic inflammatory condition. Given patients with COPD continue to experience exacerbations despite the availability of effective therapies, anti-inflammatory treatments targeting novel pathways are needed. Kinases, notably the phosphoinositide 3-kinases (PI3K), are thought to be involved in chronic airway inflammation, with this pathway proposed as a critical regulator of inflammation and oxidative stress response in COPD. CHF6523 is an inhaled PI3Kδ inhibitor that has shown positive preclinical results. This manuscript reports the results of a study of CHF6523 in patients with stable COPD (chronic bronchitis phenotype), and who had evidence of type-2 inflammation. Methods This randomised, double-blind, placebo-controlled, two-way crossover study comprised two 28-day treatment periods separated by a 28-day washout. Patients (N = 44) inhaled CHF6523 in one period, and placebo in the other, both twice daily. The primary objective was to assess the safety and tolerability of CHF6523; the secondary objective was to assess CHF6523 pharmacokinetics. Exploratory endpoints included target engagement (the relative reduction in phosphatidylinositol (3,4,5)-trisphosphate [PIP3]), pharmacodynamic evaluations such as airflow obstruction, and hyperinflation, and to identify biomarker(s) of drug response using proteomics and transcriptomics. Results CHF6523 plasma pharmacokinetics were characterised by an early maximum concentration (Cmax), reached 15 and 10 min after dosing on Days 1 and 28, respectively, followed by a rapid decline. Systemic exposure on Day 28 showed limited accumulation, with ratios

Abstract Background FOOTPRINTS® is a prospective, longitudinal, 3-year study assessing the association between biomarkers of inflammation/lung tissue destruction and chronic obstructive pulmonary disease (COPD) severity and progression in ex-smokers with mild-to-severe COPD. Here, we present baseline characteristics and select biomarkers of study subjects. Methods The methodology of FOOTPRINTS® has been published previously. The study population included ex-smokers with a range of COPD severities (Global Initiative for Chronic Obstructive Lung Disease [GOLD] stages 1–3), ex-smokers with COPD and alpha-1-antitrypsin deficiency (A1ATD) and a control group of ex-smokers without airflow limitation (EwAL). At study entry, data were collected for: demographics, disease characteristics, history of comorbidities and COPD exacerbations, symptoms, lung function and volume, exercise capacity, soluble biomarkers, and quantitative and qualitative computed tomography. Baseline data are presented with descriptive statistical comparisons for soluble biomarkers in the individual GOLD and A1ATD groups versus EwAL. Results In total, 463 subjects were enrolled. The per-protocol set comprised 456 subjects, mostly male (64.5%). The mean (standard deviation) age was 60.7 (6.9) years. At baseline, increasing pulmonary symptoms, worse lung function, increased residual volume, reduced diffusing capacity of the lung for carbon monoxide (DLco) and greater prevalence of centrilobular emphysema were observed with increasing disease severity amongst GOLD 1–3 subjects. Subjects with A1ATD (n = 19) had similar lung function parameters to GOLD 2–3 subjects, a high residual volume comparable to GOLD 3 subjects, and similar air trapping to GOLD 2 subjects. Compared with EwAL (n = 61), subjects with A1ATD had worse lung function, increased residual volume, reduced DLco, and a greater prevalence of confluent or advanced destructive emphysema. The soluble inflammatory biomarkers white blood cell count, fibrinogen, high-sensitivity C-reactive protein and plasma surfactant protein were higher in GOLD 1–3 groups than in the EwAL group. Interleukin-6 was expressed less often in EwAL subjects compared with subjects in the GOLD and A1ATD groups. Soluble receptor for advanced glycation end product was lowest in GOLD 3 subjects, indicative of more severe emphysema. Conclusions These findings provide context for upcoming results from FOOTPRINTS®, which aims to establish correlations between biomarkers and disease progression in a representative COPD population.

Patients ≥ 40 years of age with symptomatic COPD were randomized 1:1 to FF/UMEC/VI 100/62.5/25 mcg or BUD/FOR 400/12 mcg. In this post hoc analysis, patients were categorized by exacerbation history in the year prior to study entry (≥ 1 moderate/severe exacerbation [recent exacerbation] versus no recent exacerbation). Endpoints included annual rate of on-treatment moderate/severe exacerbations up to Week 24, annual rate of on-treatment severe exacerbations up to Week 24, change from baseline in trough forced expiratory volume in 1 second at Week 24, and change from baseline in health status as measured by St George’s respiratory questionnaire total score at Week 24.Results: Of the 1810 patients in the intent-to-treat population, 1180 (65%) had one or more moderate/severe exacerbation in the year prior to entry, while 630 (35%) patients did not. FF/UMEC/VI versus BUD/FOR significantly reduced moderate/severe exacerbation rates in the recent exacerbation subgroup (mean annualized rate: 0.19 vs 0.29; rate ratio [95% confidence interval [CI]]: 0.64: [0.45, 0.91]; p=0.014) and numerically reduced moderate/severe exacerbation rates in the no recent exacerbation subgroup (mean annualized rate: 0.29 vs 0.43; rate ratio [95% CI]: 0.67 [0.43, 1.04]; p=0.073). Severe exacerbation rates were numerically reduced with FF/UMEC/VI versus BUD/FOR treatment across both subgroups. FF/UMEC/VI conferred significant improvements in lung function and health status versus BUD/FOR, regardless of recent exacerbation history.Conclusion: FF/UMEC/VI reduced moderate/severe and severe exacerbation rates and improved lung function and health status versus BUD/FOR in patients with symptomatic COPD, regardless of recent exacerbation history.Keywords: COPD, exacerbations, severe exacerbations, triple therapy, ICS/LABA

Background: Prostaglandin D2 receptor 2 (DP2) antagonists inhibit prostaglandin D2-induced effects, including recruitment and activation of cells driving asthma pathogenesis. However, challenges identifying target population and end points persist.Research Question: What is the effect of the DP2 antagonist GB001 on asthma worsening in patients with moderate to severe eosinophilic asthma?Study Design and Methods: In this phase IIb, randomized, double-blind, placebo-controlled, dose-ranging, parallel-group, multicenter study, GB001 or placebo was added to standard-of-care treatment in patients with moderate to severe asthma with a blood eosinophil count ≥ 250 cells/μL. Patients aged ≥ 18 years to < 75 years received one of four once-daily treatments (GB001 20 mg, 40 mg, or 60 mg or placebo). The primary end point was the proportion of patients who experienced asthma worsening by 24 weeks. Efficacy analyses were performed for the intention-to-treat population and safety analyses for patients who received at least one dose of study treatment.Results: A total of 480 patients were treated. The ORs for asthma worsening for GB001 20 mg, 40 mg, and 60 mg vs placebo were 0.674 (95% CI, 0.398-1.142), 0.677 (95% CI, 0.399-1.149), and 0.651 (95% CI, 0.385-1.100), respectively. Analysis according to baseline blood eosinophil levels and/or fractional exhaled nitric oxide did not show greater treatment effects with higher values. Elevated liver aminotransferase levels and adverse events leading to discontinuation were more frequent for GB001 60 mg than with placebo, GB001 20 mg, and GB001 40 mg.Interpretation: Although GB001 did not significantly reduce the odds of asthma worsening, reductions favoring GB001 were observed. Treatment effects were consistent regardless of high/low type 2 phenotype. The overall safety profile was acceptable, although GB001 60 mg was associated with risk of liver injury.Clinical Trial Registration: ClinicalTrials.gov; No.: NCT03683576; URL: www.Clinicaltrials: gov.
