Indacaterol and glycopyrronium versus indacaterol on body plethysmography measurements in COPD-a randomised controlled study.

ABSTRACT: Dual bronchodilator therapy is recommended for symptomatic patients with chronic obstructive pulmonary disease (COPD). There are limited data on effects of a combination of two long-acting bronchodilators on lung function including body plethysmography.This multicentre, randomised, double-blind, single-dose, cross-over, placebo-controlled study evaluated efficacy and safety of the free combination of indacaterol maleate (IND) and glycopyrronium bromide (GLY) versus IND alone on spirometric and body plethysmography parameters, including inspiratory capacity (IC), forced expiratory volume in 1 s (FEV1), forced vital capacity (FVC), total lung capacity (TLC) and airway resistance (Raw) in moderate-to-severe COPD patients.Seventy-eight patients with FEV1 % pred. (mean?±?SD) 56?±?13% were randomised. The combination of IND?+?GLY versus IND presented a numerically higher peak-IC (??=?0.076 L, 95% confidence interval [CI]: -0.010 - 0.161 L; p?=?0.083), with a statistically significant difference in mean IC over 4 h (??=?0.054 L, 95%CI 0.022 - 0.086 L; p?=?0.001). FEV1, FVC and Raw, but not TLC, were consistently significantly improved by IND?+?GLY compared to IND alone. Safety profiles of both treatments were comparable.The free combination of IND?+?GLY improved lung function parameters as evaluated by spirometry and body plethysmography, with a similar safety profile compared to IND alone.NCT01699685.

Project description:BackgroundAddition of a second bronchodilator from a different pharmacological class may benefit patients with moderate-to-severe chronic obstructive pulmonary disease (COPD) whose symptoms are insufficiently controlled by bronchodilator monotherapy. GLOW6 evaluated the efficacy and safety of once-daily coadministration of the long-acting β2-agonist indacaterol (IND) and the long-acting muscarinic antagonist glycopyrronium (GLY) versus IND alone in patients with moderate-to-severe COPD.Materials and methodsIn this randomized, double-blind, parallel group, placebo-controlled, 12-week study, patients were randomized 1:1 to IND 150 μg and GLY 50 μg daily (IND + GLY) or IND 150 μg daily and placebo (IND + PBO) (all delivered via separate Breezhaler® devices). The primary objective was to demonstrate the superiority of IND + GLY versus IND + PBO for trough forced expiratory volume in 1 second (FEV1) at week 12. Other end points included trough FEV1 at day 1, FEV1 area under the curve from 30 minutes to 4 hours (AUC30min-4h), peak FEV1, inspiratory capacity and trough forced vital capacity (FVC) at day 1 and week 12, and transition dyspnea index (TDI) focal score, COPD symptoms, and rescue medication use over 12 weeks.ResultsA total of 449 patients were randomized (IND + GLY, 226; IND + PBO, 223); 94% completed the study. On day 1 and at week 12, IND + GLY significantly improved trough FEV1 versus IND + PBO, with treatment differences of 74 mL (95% CI 46-101 mL) and 64 mL (95% CI 28-99 mL), respectively (both P<0.001). IND + GLY significantly improved postdose peak FEV1, FEV1 AUC30min-4h, and trough FVC at day 1 and week 12 versus IND + PBO (all P<0.01). TDI focal score and COPD symptoms (percentage of days able to perform usual daily activities and change from baseline in mean daytime respiratory score) were significantly improved with IND + GLY versus IND + PBO (P<0.05). The incidence of adverse events was similar for the two treatment groups.ConclusionIn patients with moderate-to-severe COPD, once-daily coadministration of IND and GLY provides significant and sustained improvement in bronchodilation versus IND alone from day 1, with significant improvements in patient-centered outcomes.

Project description:BackgroundPhysical activity limitation is common in chronic obstructive pulmonary disease (COPD), and is associated with worse health status, and increased hospitalisation and mortality. Long-acting bronchodilators, either alone or in combination, have been shown to improve exercise intolerance. However, none of these studies were designed with physical activity as primary outcome. This study assessed the effect of indacaterol/glycopyrronium fixed dose combination (IND/GLY) 110/50 μg once daily (OD) versus placebo on lung hyperinflation (inspiratory capacity [IC]) and physical activity in patients with moderate-to-severe COPD.MethodsIn this multicentre, randomised, double-blind, placebo-controlled crossover study, patients received IND/GLY or placebo OD in two 21-day treatment periods (14-day washout between periods). Eligible patients were ≥40 years of age, current or ex-smokers (smoking history ≥10 pack-years), with post-salbutamol forced expiratory volume in 1 s (FEV1) 40-80 % predicted, and FEV1:forced vital capacity <0.70. The co-primary endpoints were peak IC after 21 days and average daily activity-related energy expenditure. Key secondary endpoints were average number of steps per day and the duration of at least moderate activity per day. Peak IC and FEV1 on Day 1, and trough IC and FEV1 after 21 days were other secondary endpoints.ResultsA total of 194 patients were randomised (65.5 % male, mean age 62.8 years, mean FEV1 61.6 % predicted), with 183 (94.3 %) completing the study. Compared with placebo, IND/GLY significantly increased peak IC after 21 days (difference 202 mL, p < 0.0001), activity-related energy expenditure (difference 36.7 kcal/day, p = 0.040), and the average number of steps per day (difference 358, p = 0.029), with a trend towards an improvement in the duration of at least moderate activity (difference 4.4 min, p = 0.264). IND/GLY was associated with statistically significant improvements versus placebo in peak IC and FEV1 on Day 1, and trough IC and FEV1 after 21 days. The incidence of treatment-emergent adverse events was 22.8 % with IND/GLY and 22.9 % with placebo.ConclusionsIn this study, compared with placebo, IND/GLY reduced hyperinflation, and, despite no patient education or lifestyle advice, improved daily physical activity levels. This suggests that IND/GLY has the potential to impact two of the main clinical concerns in the care of patients with COPD.Trial registrationClinicalTrials.gov number: NCT01996319 .

Project description:BACKGROUND:The burden of chronic obstructive lung disease (COPD) is increasing in women, with recent evidence suggesting gender differences in disease characteristics and potentially in treatment outcomes. METHODS:FLAME was a 52-week randomized controlled trial in patients with severe-to-very-severe COPD and a history of exacerbations. In this post-hoc analysis, gender-based baseline differences and treatment outcomes between indacaterol/glycopyrronium 110/50??g once daily (IND/GLY) and salmeterol/fluticasone 50/500 twice daily (SFC) were assessed in terms of rate of exacerbations, time-to-first exacerbation, lung function, health status, and rescue medication use. RESULTS:This post-hoc analysis included 2557 men and 805 women. Baseline characteristics differed between genders, with women being younger, having better lung function and more often experiencing ?2 exacerbations in the previous year. Compared with SFC, IND/GLY treatment was associated with reductions in the annualized rates of moderate/severe exacerbations (rate ratio [95% CI]: 0.81 [0.73-0.91], 0.89 [0.74-1.07] in men and women, respectively). Similarly, time-to-first moderate/severe exacerbation was also delayed (hazard ratio [95% CI]: 0.79 [0.70-0.89] and 0.76 [0.63-0.91] in men and women, respectively). Results were similar for all (mild/moderate/severe) exacerbations. Improvements in lung function, health status and rescue medication use with IND/GLY vs SFC were comparable between men and women. The smaller sample size for women may account for some observed discrepancies in treatment responses. CONCLUSIONS:Although there were gender differences in baseline characteristics, IND/GLY demonstrated similar trends for exacerbation prevention and lung function improvement in men and women with moderate-to-very-severe COPD and a history of exacerbations compared with SFC. Small differences in the effects seen between genders may be attributed to the different sizes of the two groups and need to be further evaluated in randomized trials that are appropriately powered for gender analysis.

Project description:BackgroundDual bronchodilation combining a long-acting β2-agonist (LABA) and a long-acting muscarinic antagonist (LAMA) is the preferred choice of treatment recommended by the Global Initiative for Chronic Obstructive Lung Disease (GOLD) 2017 guidelines for the management of patients with moderate-to-severe chronic obstructive pulmonary disease (COPD). The once-daily (q.d.) fixed-dose combination (FDC) of LABA, indacaterol 110 μg and LAMA, glycopyrronium 50 μg (IND/GLY 110/50 μg q.d.) demonstrated superior improvements in lung function, dyspnoea and overall health status and better tolerability against LABA or LAMA monotherapies and combination of LABA and inhaled corticosteroid (ICS) in more than 11,000 patients with moderate-to-severe COPD in several randomised controlled clinical trials.MethodsThe CRYSTAL study was the first, 12-week, randomised, open-label trial that evaluated the efficacy and safety of a direct switch from previous treatments to IND/GLY 110/50 μg q.d. on lung function and dyspnoea in patients with moderate COPD and a history of up to one exacerbation in the previous year. Patients were divided into 2 groups according to their background therapy and symptom scores and were randomised (3:1) to IND/GLY or to continue with their previous treatments.ResultsThe study included 4389 randomised patients, of whom 2160 were in groups switched to IND/GLY (intention-to-treat population). The effect of IND/GLY was superior to LABA + ICS on trough forced expiratory volume in 1 s (FEV1; treatment difference, Δ = +71 mL) and transition dyspnoea index (TDI; [Δ = 1.09 units]), and to LABA or LAMA on trough FEV1 (Δ = +101 mL) and a TDI (Δ = 1.26 units). Improvements in health status and lower rescue medication use were also observed with IND/GLY. The safety profile of the study medication was similar to that observed in previous studies.ConclusionsIND/GLY demonstrated superior improvements in lung function and dyspnoea after direct switch from previous treatments.Trial registrationClinicalTrials.gov number: NCT01985334 .
