Efficacy and safety of coadministration of once-daily indacaterol and glycopyrronium versus indacaterol alone in COPD patients: the GLOW6 study.

ABSTRACT: Addition 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 ?2-agonist indacaterol (IND) and the long-acting muscarinic antagonist glycopyrronium (GLY) versus IND alone in patients with moderate-to-severe COPD.In this randomized, double-blind, parallel group, placebo-controlled, 12-week study, patients were randomized 1:1 to IND 150 ?g and GLY 50 ?g daily (IND + GLY) or IND 150 ?g 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.A 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.In 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:BackgroundTwo once-daily long-acting muscarinic antagonists (LAMAs) are currently available for the treatment of chronic obstructive pulmonary disease (COPD) - tiotropium and glycopyrronium. Previous studies have compared glycopyrronium with open-label tiotropium. In the GLOW5 study, we compare glycopyrronium with blinded tiotropium.MethodsIn this blinded, double-dummy, parallel group, 12-week study, patients with moderate-to-severe COPD were randomized 1:1 to glycopyrronium 50 μg once daily or tiotropium 18 μg once daily. The primary objective was to demonstrate the non-inferiority of glycopyrronium versus blinded tiotropium with respect to trough forced expiratory volume in 1 second (FEV1) following 12 weeks of treatment (non-inferiority margin: -50 mL). Secondary objectives were to evaluate glycopyrronium versus tiotropium for other spirometric outcomes, breathlessness (Transition Dyspnea Index; TDI), health status (St George's Respiratory Questionnaire; SGRQ), daily rescue medication use, COPD exacerbations and COPD symptoms over 12 weeks of treatment.Results657 patients were randomized (glycopyrronium: 327; tiotropium: 330); 96% (630 patients) completed the study. Least squares mean trough FEV1 for both glycopyrronium and tiotropium was 1.405 L at Week 12, meeting the criterion for non-inferiority (mean treatment difference: 0 mL, 95% CI: -32, 31 mL). Glycopyrronium demonstrated rapid bronchodilation following first dose on Day 1, with significantly higher FEV1 at all time points from 0-4 h post-dose versus tiotropium (all p < 0.001). FEV1 area under the curve from 0-4 h (AUC0-4h) post-dose with glycopyrronium was significantly superior to tiotropium on Day 1 (p < 0.001) and was comparable to tiotropium at Week 12. Glycopyrronium demonstrated comparable improvements to tiotropium in TDI focal score, SGRQ total score, rescue medication use and the rate of COPD exacerbations (all p = not significant). Patients on glycopyrronium also had a significantly lower total COPD symptom score versus patients on tiotropium after 12 weeks (p = 0.035). Adverse events were reported by a similar percentage of patients receiving glycopyrronium (40.4%) and tiotropium (40.6%).ConclusionIn patients with moderate-to-severe COPD, 12-week blinded treatment with once-daily glycopyrronium 50 μg or tiotropium 18 μg, provided similar efficacy and safety, with glycopyrronium having a faster onset of action on Day 1 versus tiotropium.

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 .

Project description:BackgroundThe objective of this study was to evaluate the comparative efficacy of indacaterol 75 ?g once daily (OD), tiotropium 18 ?g OD, salmeterol 50 ?g twice daily (BID), formoterol 12 ?g BID, and placebo for the treatment of chronic obstructive pulmonary disease (COPD) based on individual patient data (IPD) from randomized controlled trials (RCTs) from the indacaterol trial program and aggregate data (AD) identified from a systematic review of RCTs.Methods22 RCTs were included in the AD analysis that evaluated: indacaterol 75 ?g (n = 2 studies), indacaterol 150??g n = 5 (i.e. salmeterol 50 ?g) (n = 5), indacaterol 300 ?g (n = 2), tiotropium 18 ?g (n = 10), salmeterol 50 ?g (n = 7), and formoterol 12 ?g (n = 4). All of the studies except for one head-to-head comparison (tiotropium vs. salmeterol) were placebo controlled. Outcomes of interest were trough forced expiratory volume in 1 second (FEV1) and St. George's Respiratory Questionnaire (SGRQ) total score at week 12. The AD from all trials was analysed simultaneously using a Bayesian network meta-analysis (NMA) and relative treatment effects between all regimens were obtained. In a separate analysis, the IPD available from the 6 indacaterol RCTs was analysed in a NMA. Treatment-by-covariate interactions were included in both analyses to improve similarity of the trials.ResultsAll interventions compared were more efficacious than placebo regarding FEV1 at 12 weeks. Indacaterol 75 ?g is expected to result in a comparable FEV1 at 12 weeks to tiotropium and salmeterol based on both IPD and AD analyses. In comparison to formoterol, the IPD and AD results indicate indacaterol 75 ?g is more efficacious (IPD = 0.07 L difference; 95%Credible Interval (CrI) 0.02 to 0.11; AD = 0.05 L difference; 95%CrI 0.01; 0.09). In terms of SGRQ total score at 12 weeks, indacaterol 75 ?g and formoterol were more efficacious than placebo, whereas for tiotropium and salmeterol the credible intervals included zero for the AD results only (tiotropium: -2.99 points improvement versus placebo; 95%CrI -6.48 to 0.43; salmeterol:-2.52; 95%CrI: -5.34; 0.44). Both IPD and AD results suggest that indacaterol 75 ?g is expected to be comparable to all active treatments.ConclusionsBased on a synthesis of currently available AD RCT evidence as well as an IPD network meta-analysis of six RCTs, indacaterol 75 ?g is expected to be at least as efficacious as formoterol and comparable to tiotropium and salmeterol regarding FEV1. Furthermore, indacaterol 75 ?g shows comparable level of improvement in health-related quality of life to tiotropium, salmeterol, and formoterol, as measured by the SGRQ.

Project description:BackgroundIndacaterol acetate (IND), a long-acting β2-agonist in combination with mometasone furoate (MF), an inhaled corticosteroid (ICS), is being explored as a once-daily (od) treatment for asthma in children. This study examined the efficacy, safety, and systemic exposure of IND 75 µg and IND 150 µg in children with persistent asthma.MethodsIn this Phase IIb, multicenter, randomized, double-blind, parallel-group study, pediatric patients (aged ≥ 6 to < 12 years) with persistent asthma were randomized (1:1) to receive either IND 75 µg od or IND 150 µg od via Breezhaler® in combination with ICS background therapy. The primary endpoint was change from baseline in pre-dose trough forced expiratory volume in one second (FEV1) after two weeks of treatment.ResultsIn total, 80 patients received IND 75 µg (n = 39) or IND 150 µg (n = 41). The study met its primary endpoint; both doses demonstrated improvements in pre-dose trough FEV1 from baseline to Day 14 (mean change [Δ]: 212 mL, IND 75 µg; 171 mL, IND 150 µg). The secondary spirometry parameters (post-dose FEV1 after 1-h, post-dose forced vital capacity; morning and evening peak expiratory flow) also improved. Overall, 36.1% in IND 75 μg group and 25% patients in IND 150 μg group achieved a decrease from baseline in Pediatric Interviewer-administered Asthma Control Questionnaire score of ≥ 0.5 units. A dose-dependent increase in plasma IND concentration was noted between the two groups. Both IND doses demonstrated an acceptable safety profile.ConclusionsOnce-daily IND 75 μg and IND 150 μg via Breezhaler® in combination with background ICS therapy provided substantial bronchodilation in children with asthma and were well tolerated. Taken together, these clinical and systemic exposure findings support IND 75 μg as the most appropriate dose for evaluation in Phase III trials in combination with MF in pediatric asthma.Trial registrationClinicalTrials.gov (NCT02892019; 08-Sep-2016).
