ABSTRACT
Background: Chronic obstructive pulmonary disease (COPD) exacerbations are difficult outcomes to measure in clinical trials. It would be valuable to be able to predict which patients are likely to benefit in terms of exacerbation prevention based on their early response in lung function and symptoms. Methods: This was a post-hoc analysis from the 52-week, randomized, double-blind, double-dummy, non-inferiority FLAME trial. Early clinically important improvement (ECII) was defined as achievement of minimal clinically important difference in trough forced expiratory volume in 1 second (FEV1; ≥100 mL increase) and one patient-reported outcome (PRO): either St. George's Respiratory Questionnaire for COPD (≥4-unit reduction; D1), or COPD assessment test (≥2-point reduction; D2) at Week 4 or 12. Results: Approximately 18-20% of patients achieved ECII at Week 4 or 12 post-randomization according to any of the two definitions. The rate of subsequent exacerbations was lower in patients who achieved ECII at Week 4 (D1: ratio of rates [95% CI], 0.85 [0.74 to 0.98]; D2, 0.88 [0.77 to 1.00]) or at Week 12 (D1, 0.85 [0.74 to 0.98]; D2, 0.86 [0.75 to 1.00]) versus patients not achieving ECII. Patients who achieved ECII experienced longer time-to-first exacerbation between Week 4 or 12 to end of study. More patients achieved ECII with indacaterol/glycopyrronium versus salmeterol/fluticasone according to both definitions at Week 4 (D1, odds ratio [95% CI], 1.69 [1.40 to 2.04]; D2, 1.61 [1.34 to 1.93]), and 12 (D1, 2.01 [1.66 to 2.44]; D2, 1.80 [1.48 to 2.18]). Conclusion: ECII is a novel composite endpoint, based on clinically relevant improvement in lung function and PROs in the early phase of treatment intervention that may predict subsequent exacerbation risk and may be used in clinical trials.

BACKGROUND: COPD is a heterogeneous disease and patients may respond differently to therapies depending on baseline symptom burden. METHODS: This post-hoc analysis from the 52-week FLAME study investigated the impact of baseline symptom burden in terms of health status, dyspnoea, bronchitis status, eosinophil levels and smoking status on the subsequent risk of moderate or severe exacerbations. Health status was measured by St. George's Respiratory Questionnaire (SGRQ) score (higher ≥46.6 and lower < 46.6) and COPD Assessment Test (CAT) score (higher ≥17 and lower < 17); dyspnoea and bronchitis were assessed via an electronic diary (eDiary). Differential response to once-daily indacaterol/glycopyrronium (IND/GLY) 110/50 µg versus twice-daily salmeterol/fluticasone (SFC) 50/500 µg was assessed. RESULTS: Data from 3354 patients was analysed. The risk of exacerbations was lower in patients who had less severe health impairment (rate ratio [RR] [95% CI]): SGRQ-C, (0.88 [0.78, 0.99]); CAT, 0.85 [0.75, 0.96]) and lower dyspnoea (0.79 [0.69, 0.90]) at baseline versus those with more severe health impairment and higher dyspnoea, respectively. Compared with SFC, IND/GLY led to better prevention of moderate-to-severe exacerbations in the majority of groups studied. CONCLUSION: Patients with more severe health status impairment and greater symptom burden at baseline subsequently experienced more exacerbations in the FLAME study. IND/GLY was overall more effective in preventing exacerbations versus SFC, regardless of baseline symptom burden. Our results suggest that future studies on novel exacerbation therapies should consider targeting patients with higher symptom burden at baseline. CLINICAL TRIAL IDENTIFIER: NCT01782326.

RATIONALE: Chronic obstructive pulmonary disease exacerbations accelerate lung function decline, reduce quality of life, and increase mortality. A subset of patients (n = 457) from the FLAME (Effect of Indacaterol Glycopyrronium vs. Fluticasone Salmeterol on COPD Exacerbations) study used the Exacerbations of COPD Tool (EXACT) to capture symptom-defined exacerbations. OBJECTIVES: To evaluate the effect of indacaterol/glycopyrronium versus salmeterol/fluticasone on symptom-defined exacerbations measured using EXACT, and to assess differences between these events and exacerbations requiring healthcare resource use (HCRU). METHODS: All patients in FLAME used an electronic diary to record and detect symptom deteriorations; HCRU-related exacerbations were confirmed by investigators. In patients using the EXACT questionnaire, the onset, recovery, and magnitude of symptom-defined exacerbations were identified by changes in total scores relative to baseline. We analyzed the annualized rate and time to first symptom-defined (EXACT) exacerbation and assessed differences between symptom-defined and HCRU events in terms of number, severity, and concordance. MEASUREMENTS AND MAIN RESULTS: A nonsignificant 17% reduction in the annualized rate of symptom-defined (EXACT) exacerbations (rate ratio, 0.83; 95% confidence interval [CI], 0.60-1.14; P = 0.242) and a numerically longer time to first symptom-defined exacerbation were observed with indacaterol/glycopyrronium versus salmeterol/fluticasone (hazard ratio, 0.76; 95% CI, 0.56-1.03; P = 0.075). These results were consistent with data from the overall FLAME population. Of the symptom-defined (EXACT) events, 23.5% corresponded to HCRU events, and 22.2% of HRCU events were captured by EXACT (κ index, 0.24; 95% CI, 0.15-0.33). CONCLUSIONS: Regardless of the exacerbation definition used, our findings support the use of long-acting ß2 agonists/long-acting muscarinic receptor antagonists as the preferred treatment option for patients at risk of future exacerbations.

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is a progressive disease and a composite endpoint could be an indicator of treatment effect on disease worsening. This post-hoc analysis assessed whether indacaterol/glycopyrronium (IND/GLY) 110/50 µg once daily reduced the risk of clinically important deterioration (CID) versus salmeterol/fluticasone (SFC) 50/500 µg twice daily in moderate-to-very severe COPD patients from the FLAME study. METHODS: CID was defined as ≥100 mL decrease in forced expiratory volume in 1 s (FEV1) or ≥ 4-unit increase in St. George's Respiratory Questionnaire (SGRQ) total score or a moderate-to-severe COPD exacerbation. Changes from baseline in the rate of moderate and severe exacerbations, time to first moderate-to-severe exacerbation, and change from baseline in the SGRQ score, measured after Week 12 up to Week 52, were assessed by presence of early CID (CID+) or absence of CID (CID-) at Week 12. RESULTS: IND/GLY significantly delayed the time to CID (hazard ratio [HR] (95% confidence interval [CI]), 0.72 [0.67-0.78]; P < 0.0001), and reduced the incidences of CID versus SFC. Additionally, IND/GLY delayed the time to CID in all patient subgroups. After 12 weeks until 52 weeks, CID+ patients had a significantly higher rate of moderate-to-severe exacerbations versus CID- patients (P < 0.0001); moreover, CID+ patients experienced moderate-to-severe exacerbations significantly earlier versus CID- patients (P < 0.0001). CID+ patients had a comparable change in the SGRQ total score versus CID- patients. CONCLUSIONS: IND/GLY reduced the risk of CID versus SFC. CID had a significant impact on long-term exacerbation outcomes in patients with moderate-to-very severe COPD and a history of ≥1 exacerbations in the previous year.

RATIONALE: There are no studies on withdrawal of inhaled corticosteroids in patients on long-term triple therapy in the absence of frequent exacerbations. OBJECTIVES: To evaluate the efficacy and safety of direct de-escalation from long-term triple therapy to indacaterol/glycopyrronium in nonfrequently exacerbating patients with chronic obstructive pulmonary disease (COPD). METHODS: This 26-week, randomized, double-blind, triple-dummy study assessed the direct change from long-term triple therapy to indacaterol/glycopyrronium (110/50 µg once daily) or continuation of triple therapy (tiotropium [18 µg] once daily plus combination of salmeterol/fluticasone propionate [50/500 µg] twice daily) in nonfrequently exacerbating patients with moderate-to-severe COPD. Primary endpoint was noninferiority on change from baseline in trough FEV1. Moderate or severe exacerbations were predefined secondary endpoints. MEASUREMENTS AND MAIN RESULTS: A total of 527 patients were randomized to indacaterol/glycopyrronium and 526 to triple therapy. Inhaled corticosteroids withdrawal led to a reduction in trough FEV1 of -26 ml (95% confidence interval, -53 to 1 ml) with confidence limits exceeding the noninferiority margin of -50 ml. The annualized rate of moderate or severe COPD exacerbations did not differ between treatments (rate ratio, 1.08; 95% confidence interval, 0.83 to 1.40). Patients with ≥300 blood eosinophils/µl at baseline presented greater lung function loss and higher exacerbation risk. Adverse events were similar in the two groups. CONCLUSIONS: In patients with COPD without frequent exacerbations on long-term triple therapy, the direct de-escalation to indacaterol/glycopyrronium led to a small decrease in lung function, with no difference in exacerbations. The higher exacerbation risk in patients with ≥300 blood eosinophils/µl suggests that these patients are likely to benefit from triple therapy.

BACKGROUND: The FLAME study compared once-daily indacaterol/glycopyrronium (IND/GLY) 110/50 µg with twice-daily salmeterol/fluticasone (SFC) 50/500 µg in symptomatic patients with moderate to very severe COPD and a history of exacerbations in the previous year. METHODS: This prespecified and post hoc subgroup analysis evaluated treatment efficacy on 1) moderate/severe exacerbations according to prior exacerbation history and treatment, and 2) types of exacerbations according to health care resource utilization (HCRU) during 1-year follow-up. RESULTS: IND/GLY reduced the rate of moderate/severe exacerbations versus SFC in patients with a history of 1 exacerbation (rate ratio [RR]: 0.83, 95% CI: 0.75-0.93), ≥2 exacerbations (RR: 0.85, 95% CI: 0.70-1.03) and ≥2 exacerbations or ≥1 hospitalization in the previous year (RR: 0.86, 95% CI: 0.74-1.00). Prolonged time-to-first exacerbation was observed in all the groups according to exacerbation history. Moderate/severe exacerbations decreased with IND/GLY versus SFC, independent of previous treatment. IND/GLY significantly reduced rates of moderate/severe exacerbations treated with antibiotics (RR: 0.79, 95% CI: 0.67-0.93) and systemic corticosteroids and antibiotics (RR: 0.80, 95% CI: 0.70-0.91); rates of exacerbations treated with systemic corticosteroids alone were comparable (RR: 0.99, 95% CI: 0.80-1.22). CONCLUSION: Overall, IND/GLY demonstrated consistent beneficial effects versus SFC on moderate/severe exacerbations, independent of prior exacerbation history or treatment. The efficacy of IND/GLY on exacerbation prevention was superior to SFC for exacerbations treated with antibiotics with/without systemic corticosteroids and was similar for exacerbations treated with systemic corticosteroids alone.

An exacerbation of chronic obstructive pulmonary disease (COPD) is an acute worsening of respiratory symptoms accompanied by a variable degree of physiological deterioration. The traditional assessment of an exacerbation consists of the reporting of symptoms by the patient to a clinician and subsequent clinical assessment. It would be valuable to also gather symptom reports directly from patients, and thus patient-reported outcome (PRO) tools should be ideally suited to the evaluation of COPD exacerbations. However, most pharmaceutical industry- and large academy-sponsored studies have used a healthcare resource use definition alone, which is based on sustained worsening of a patient's condition from the stable state that requires a change in regular medication. This Review explores the use of PROs for the detection, quantification, and evaluation of COPD exacerbations. It examines symptom diary cards as exacerbation detection tools and their evolution into electronic diaries used in pharmaceutical trials. This paper also describes the development of specifically designed PROs that have been used in exacerbation settings, focusing on the Exacerbations and Symptoms in COPD e-Diary, Exacerbations of Chronic Obstructive Pulmonary Disease Tool, COPD Assessment Test, and Chronic Respiratory Disease Questionnaire, highlighting the strengths and weaknesses of these instruments. We describe the effectiveness of these tools to enhance exacerbation reporting; quantify exacerbation characteristics, including the frequency, duration, and severity of events; and evaluate the outcome. We also explore the potential use of PROs in future studies to discriminate the effect of therapies on different exacerbation phenotypes and thus enhance personalized therapeutic approaches.

Indacaterol/glycopyrronium (IND/GLY) 110/50mcg was the first once-daily, long-acting ß2-agonist (LABA)/long-acting muscarinic antagonist (LAMA) fixed-dose combination (FDC) approved in Europe for the treatment of chronic obstructive pulmonary disease (COPD). Development of IND/GLY was driven by the need to improve the standard of care for patients with this disease, in terms of symptom control and exacerbation frequency. IGNITE, an adaptive, comprehensive, and innovative Phase 3 development program, demonstrated the efficacy of IND/GLY in optimising bronchodilation, reducing symptoms, and reducing exacerbations in patients with COPD. IGNITE challenged contemporary thinking about the pharmacological treatment and management of patients with this disease.

BACKGROUND: In clinical trials of inhaled bronchodilators, chronic obstructive pulmonary disease (COPD) guidelines recommend that patient-reported outcomes (PROs) are assessed alongside lung function. How these endpoints are related is unclear. METHODS: Pooled longitudinal data from 23 randomised controlled COPD studies were analyzed (Nâ¯=â¯23,213). Treatments included long-acting ß2 agonists, long-acting muscarinic antagonists (LABAs or LAMAs) and the LABA/LAMA combination QVA149. Outcome measures were Transition Dyspnoea Index (TDI) and St. George's Respiratory Questionnaire (SGRQ) scores, COPD exacerbation frequency and rescue medication use. Relationships between changes in trough forced expiratory volume in one second (ΔFEV1) and outcomes following treatment were assessed using correlations of data summaries and model-based analysis: generalized linear mixed-effect regression modelling to determine if ΔFEV1 could predict patient outcomes with different treatments. RESULTS: Mean age was 64 years, 73% were male, and most had moderate (45%) or severe (52%) disease. Statistically significant correlations were observed between ΔFEV1 and each outcome measure (exacerbations Rsâ¯=â¯0.05; rescue medication, SGRQ, TDI, râ¯=â¯0.11-0.16; all pâ¯<â¯.001). Patients with greater improvements in trough FEV1 had on average better SGRQ and TDI scores, fewer exacerbations, and used less rescue medication. For SGRQ and TDI scores, minimal clinically important differences were observed over the range of pooled ΔFEV1 values. Model-based predictions confirmed the treatment effect was partly explained by changes in FEV1 from baseline with improvements in PROs observed across all treatments when trough FEV1 improved. Across all endpoints active treatments were better than placebo (pâ¯<â¯.0001), and LABA/LAMA treatment resulted in numerically better treatment outcomes than either monocomponent. CONCLUSIONS: These data suggest that FEV1 improvements post-bronchodilation correlate with PRO improvements. Further improvements in patient outcomes may be expected by maximizing lung function improvements.

PURPOSE: To compare the efficacy and safety of two long-acting dual bronchodilator combinations: indacaterol/glycopyrrolate (IND/GLY) versus umeclidinium/vilanterol (UMEC/VI). METHODS: Studies A2349 and A2350 were replicate, randomized, double-blind, double-dummy, active-controlled, cross-over studies in patients with moderate-to-severe COPD. Patients were randomized to sequential 12-week treatments of twice-daily IND/GLY 27.5/15.6 µg and once-daily UMEC/VI 62.5/25 µg, each separated by a 3-week washout. The primary objective was to demonstrate non-inferiority of IND/GLY compared with UMEC/VI in terms of the 24-h forced expiratory volume in 1 s profile at week 12 (FEV1 AUC0-24). Rescue medication use, symptom control, and safety were assessed throughout. RESULTS: Both treatments delivered substantial bronchodilation over 12 weeks, with improvements in FEV1 AUC0-24h at week 12 of 232 and 185 mL for IND/GLY, and 244 and 203 mL with UMEC/VI in Studies A2349 and A2350, respectively. The primary efficacy objective of non-inferiority of IND/GLY relative to UMEC/VI was not met as the lower bound of the confidence interval for the LS treatment comparison was below the pre-specified non-inferiority margin of -20 mL in both studies: -26.9 and -34.2 mL, respectively (LS mean between-treatment differences: -11.5 and -18.2 mL). Both drugs were well tolerated, with AE profiles consistent with their respective prescribing information. CONCLUSIONS: IND/GLY and UMEC/VI provided clinically meaningful and comparable bronchodilation. Non-inferiority of IND/GLY to UMEC/VI could not be declared although between-treatment differences were not clinically relevant. The data support the use of IND/GLY as an efficacious and well tolerated treatment option in patients with COPD. (ClinicalTrials.gov NCT02487446 and NCT02487498).

In this pooled analysis, we compared the effect of indacaterol/glycopyrronium (IND/GLY) by sex versus other commonly used chronic obstructive pulmonary disease (COPD) treatments and placebo. Male and female patients with moderate-to-very-severe COPD who had participated in six randomized controlled trials were included in the analysis. Baseline demographics and disease characteristics were analyzed by sex, and any differences noted. The effects of IND/GLY versus salmeterol/fluticasone (SFC), glycopyrronium, tiotropium and placebo, on lung function and the patient-reported outcomes (health status, dyspnea, rescue medication use and symptoms) were assessed by sex after 26 weeks treatment. The analysis population comprised 4719 men and 1389 women. Most baseline parameters differed significantly between men and women. Nonetheless, despite these differences in baseline characteristics, IND/GLY significantly improved lung function versus placebo (p < 0.0001) and all active comparators (p < 0.01) in men and women. Overall, IND/GLY showed better improvement in dyspnea and health status compared with all other treatments in both sex. Greater reduction of rescue medication use was observed with IND/GLY versus placebo and other treatments (all p < 0.01 expect IND/GLY versus SFC). Although some variability was observed, improvements in health status, dyspnea, rescue medication use and symptoms were generally larger in women than in men. Irrespective of sex, IND/GLY provided superior efficacy to monotherapy or SFC in both men and women. Small differences in efficacy response by sex were observed, which should be evaluated further in prospective clinical studies. Nevertheless, the benefits observed with IND/GLY confirm dual bronchodilator as the preferred therapy in patients with moderate-to-very-severe COPD regardless of sex.

BACKGROUND: Endpoints that evaluate deterioration rather than improvement of disease may have clinical utility in COPD. In this analysis, we compared the effects of different maintenance treatments on the prevention of clinically important deterioration (CID) in moderate-to-severe COPD patients. METHODS: Data were analyzed from three 26-week studies comparing indacaterol/glycopyrronium (IND/GLY) with tiotropium (TIO) or salmeterol/fluticasone (SFC). Two definitions of CID were used; each was a composite of three outcome measures typically associated with COPD. Definition 1 (D1) comprised a ≥100 mL decrease in forced expiratory volume in 1 second (FEV1), a ≥4-unit increase in St George's Respiratory Questionnaire, and a moderate-to-severe COPD exacerbation. In Definition 2 (D2), a ≥1-unit decrease in transition dyspnea index replaced FEV1. RESULTS: Using D1, IND/GLY significantly reduced the risk of first or sustained CID versus either TIO (hazard ratio 0.72 [0.61, 0.86], P=0.0003 and 0.73 [0.61, 0.89], P=0.001) or SFC (0.67 [0.57, 0.80] and 0.63 [0.52, 0.77], both P<0.0001). With D2, IND/GLY significantly reduced the risk of first, but not sustained, CID versus TIO (0.80 [0.64 to 0.99], P=0.0359 and 0.85 [0.66, 1.10], P=0.2208) and both first and sustained CID versus SFC (0.73 [0.61, 0.88], P=0.001 and 0.72 [0.58, 0.90], P=0.0036). CONCLUSION: These data confirm the utility of the CID endpoint as a means of monitoring COPD worsening in patients with moderate-to-severe COPD. Using the CID measure, we demonstrated that dual bronchodilation with IND/GLY significantly reduced the risk of CID versus either long-acting muscarinic antagonist or long-acting ß2-agonist/inhaled corticosteroid treatment, providing further evidence for the benefit of dual bronchodilation in this patient population.

RATIONALE: Post hoc analyses suggest that blood eosinophils have potential as a predictive biomarker of inhaled corticosteroid efficacy in the management of chronic obstructive pulmonary disease (COPD). OBJECTIVES: We prospectively investigated the value of blood eosinophils as a predictor of responsiveness to an inhaled corticosteroid/long-acting ß2-agonist combination versus a long-acting ß2-agonist/long-acting muscarinic antagonist combination for exacerbation prevention. METHODS: We conducted prespecified analyses of data from the FLAME (Effect of Indacaterol Glycopyronium vs Fluticasone Salmeterol on COPD Exacerbations) study, which compared once-daily long-acting ß2-agonist/long-acting muscarinic antagonist indacaterol/glycopyrronium 110/50 µg with twice-daily long-acting ß2-agonist/inhaled corticosteroid salmeterol/fluticasone combination 50/500 µg in patients with one or more exacerbations in the preceding year. Subsequent post hoc analyses were conducted to address further cutoffs and endpoints. MEASUREMENTS AND MAIN RESULTS: We compared treatment efficacy according to blood eosinophil percentage (<2% and ≥2%, <3% and ≥3%, and <5% and ≥5%) and absolute blood eosinophil count (<150 cells/µl, 150 to <300 cells/µl, and ≥300 cells/µl). Indacaterol/glycopyrronium was significantly superior to salmeterol/fluticasone for the prevention of exacerbations (all severities, or moderate or severe) in the <2%, ≥2%, <3%, <5%, and <150 cells/µl subgroups, and at no cutoff was salmeterol/fluticasone superior to indacaterol/glycopyrronium. Furthermore, the rate of moderate or severe exacerbations did not increase with increasing blood eosinophils. The incidence of pneumonia was higher in patients receiving salmeterol/fluticasone than indacaterol/glycopyrronium in both the <2% and ≥2% subgroups. CONCLUSIONS: Our prospective analyses indicate that indacaterol/glycopyrronium provides superior or similar benefits over salmeterol/fluticasone regardless of blood eosinophil levels in patients with COPD.

BACKGROUND: The FLAME study demonstrated that indacaterol/glycopyrronium (IND/GLY), the fixed-dose combination of a long-acting ß2-agonist (LABA, IND) and a long-acting muscarinic antagonist (LAMA, GLY), was superior to salmeterol/fluticasone combination (SFC) in preventing exacerbations in COPD patients with a high risk of exacerbations. In this study, we report a prespecified analysis of the efficacy and safety of IND/GLY versus SFC in Asian patients from the FLAME study. PATIENTS AND METHODS: Patients from Asian centers with moderate-to-very severe COPD and ≥1 exacerbation in the previous year from the 52-week, randomized FLAME study were included. IND/GLY was compared versus SFC for effects on exacerbations, lung function (forced expiratory volume in 1 second [FEV1] and forced vital capacity [FVC]), health status (St George's Respiratory Questionnaire [SGRQ]), rescue medication use, and safety. RESULTS: A total of 510 Asian patients (IND/GLY, n=250 or SFC, n=260) were included. Compared to the overall FLAME population, the Asian cohort had more males, a shorter duration of COPD, fewer patients using inhaled corticosteroid (ICS) at screening, fewer current smokers, and more patients with very severe COPD. IND/GLY significantly reduced the rate of moderate/severe exacerbations (rate ratio: 0.75; 95% confidence interval: 0.58-0.97; P=0.027) and prolonged time to first moderate/severe exacerbation versus SFC (hazard ratio: 0.77; 95% confidence interval: 0.59-1.01; P=0.055). Predose trough FEV1 and FVC significantly improved in Asian patients (P<0.001). IND/GLY improved SGRQ for COPD (SGRQ-C score; P=0.006) and reduced rescue medication use (P=0.058) at week 52. Pneumonia incidence was 3.6% with IND/GLY and 7.7% with SFC (P=0.046). CONCLUSION: In exacerbating Asian COPD patients, IND/GLY was more effective than SFC.

BACKGROUND: Indacaterol/glycopyrronium (IND/GLY) is approved for maintenance treatment of adult patients with COPD. This post hoc analysis explored the efficacy and safety of IND/GLY versus salmeterol/fluticasone (SFC) in symptomatic (Global Initiative for Chronic Obstructive Lung Disease [GOLD] B and GOLD D) patients with moderate-to-severe COPD. PATIENTS AND METHODS: Data from LANTERN and ILLUMINATE studies were pooled and analyzed. In both studies, symptomatic COPD patients were randomized to once-daily IND/GLY 110 µg/50 µg or twice-daily SFC 50 µg/500 µg. End points were pre-dose trough forced expiratory volume in one second (FEV1), standardized area under the curve for FEV1 from 0 to 12 hours (FEV1 AUC0-12 hours), peak FEV1, peak forced vital capacity (FVC), pre-dose trough FVC, Transition Dyspnea Index (TDI) total score, St George's Respiratory Questionnaire total score, rescue medication use and safety. RESULTS: A total of 1,263 patients were classified as either GOLD B (n=809) or GOLD D (n=454). At week 26, IND/GLY demonstrated statistically significant improvement in all lung function parameters versus SFC in patients in both the GOLD B and GOLD D subgroups. TDI total score and rescue medication use were significantly improved with IND/GLY versus SFC in the overall population and in the GOLD B (TDI total score only) and GOLD D (rescue medication only) subgroups. IND/GLY also reduced the rate of exacerbations in the pooled population. Overall safety profile was comparable with a higher incidence of pneumonia in the SFC-treated group. CONCLUSION: In this pooled analysis, IND/GLY demonstrated superior efficacy compared with SFC in patients in the GOLD B and GOLD D subgroups and supported its use in symptomatic COPD patients.

BACKGROUND: To better evaluate the efficacy and safety of the indacaterol/glycopyrronium (IND/GLY) fixed-dose combination versus tiotropium in Japanese patients, a pooled data analysis was conducted from the SHINE and ARISE studies, which were part of the IND/GLY clinical trial program. METHODS: Japanese patients with moderate-to-severe COPD were included in the analysis. Efficacy in terms of pre-dose forced expiratory volume in one second (FEV1) at Week 12 and Week 24/26 (ARISE/SHINE) and FEV1 at 30min and 60min post-dose at Day 1, Week 12, and Week 24/26 was evaluated. Health status using the St. George׳s Respiratory Questionnaire (SGRQ) score, rescue medication use (number of puffs/day), safety, and tolerability were also assessed. RESULTS: In total, 340 patients (IND/GLY, n=161; IND, n=41; GLY, n=40; tiotropium, n=79; and placebo, n=19) were included in the analysis that focused on comparing IND/GLY versus tiotropium since they were included in both studies. At Week 12 and Week 24/26, pre-dose FEV1 was significantly improved with IND/GLY compared with tiotropium (treatment differences=70mL and 80mL, respectively; both P≤0.001). FEV1 at 30min and 60min post-dose, the SGRQ total score, and rescue medication use were more statistically significant with IND/GLY than with tiotropium for all assessed time-points. The overall incidence of adverse events (AEs) and serious AEs was similar between the IND/GLY- and tiotropium-treated groups. CONCLUSIONS: Compared to tiotropium, IND/GLY provided significant improvements in lung function, health status, and rescue medication use, while having a good safety profile in Japanese patients with moderate-to-severe COPD.
