Clinically Important Deterioration (CID) and Ageing in COPD: A Systematic Review and Meta-Regression Analysis According to PRISMA Statement.

Clinically important deterioration (CID) is a composite endpoint developed to quantify the impact of pharmacological treatment in clinical trials for Chronic Obstructive Pulmonary Disease (COPD), also showing a prognostic value. CID is defined as any of the following condition: forced expiratory volume in 1 s decrease ≥100 mL from baseline, and/or St. George's Respiratory Questionnaire total score increase ≥4-unit from baseline, and/or the occurrence of a moderate-to-severe exacerbation of COPD. Although most COPD patients experience a clinical worsening as they get older, to date, no specific studies assessed the correlation between ageing and CID in COPD. Therefore, the aim of this study was to investigate the impact of ageing on CID in COPD patients. Data obtained from 55219 COPD patients were extracted from 17 papers, mostly post-hoc analyses. A pairwise meta-analysis and a meta-regression analysis were performed according to PRISMA-P guidelines to quantify the impact of pharmacological therapy on CID and to determine whether ageing might modulate the risk of CID in COPD patients. Inhaled treatments resulted generally effective in reducing the risk of CID in COPD (relative risk: 0.81, 95% confidence interval 0.79-0.84; P < 0.001). The meta-regression analysis indicated a trend toward significance (P = 0.063) in the linear relationship between age and the risk of CID. Of note, age significantly (P < 0.05) increased the risk of CID when associated with lower post-bronchodilator FEV1. These results were not affected by a significant risk of bias. This quantitative synthesis suggests that inhaled therapy is effective in reducing the risk of CID in COPD, although such a protective effect may be affected in older patients with impaired lung function. Further studies specifically designed on CID in COPD are needed to confirm these results.

The clinical characteristics and treatment response of patients with chronic obstructive pulmonary disease with low body mass index.

Background: This study aimed to analyze the clinical characteristics and treatment response of patients with chronic obstructive pulmonary disease (COPD) with low body mass index (BMI). Methods: In this cross-sectional study, we enrolled patients with stable COPD from the database setup by the Second Xiangya Hospital of Central South University. We classified the patients into three groups based on BMI: low-BMI (<18.5kg/m2), normal-BMI (≥18.5 and <24.0kg/m2), and high-BMI (≥24kg/m2) groups. We defined clinically important deterioration (CID) as a COPD Assessment Test (CAT) score increase of ≥2 and minimum clinically important difference (MCID) as a CAT score decrease of ≥2 during 6months of follow-up. We recorded the number of exacerbations and mortality during 1year of follow-up. Results: A total of 910 COPD patients were included with 144 (15.8%) patients in low-BMI, 475 (52.2%) in normal-BMI, and 291 (32.0%) in high-BMI groups. Patients with low BMI had worse pulmonary function, higher symptom scores, and exacerbations in the past year compared with normal- and high-BMI groups (p < 0.05). Logistic regression analysis revealed that age, Global Initiative for Chronic Obstructive Lung Disease grades 3 and 4, and hospitalizations in the past year were independent risk factors for patients with low BMI (p < 0.05). After 1year of follow-up, patients with low BMI had higher mortality and number of hospitalizations. Patients with low BMI were more likely to attain CID and less likely to attain MCID compared with patients with high BMI (p < 0.05). In addition, patients with low BMI treated with long-acting β2-agonist (LABA)+long-acting muscarinic antagonist (LAMA) and LABA+LAMA+inhaled corticosteroid (ICS) were more likely to attain MCID than those treated with LABA+ICS and LAMA (p < 0.05). Conclusion: COPD patients with low BMI had worse pulmonary function, higher symptom scores, and higher risk of future hospitalizations and mortality and were less likely to attain MCID and more likely to attain CID. It is worth noting that patients with low BMI treated with LABA+LAMA and LABA+LAMA+ICS were more likely to attain MCID than those treated with LABA+ICS and LAMA.

Clinically important deterioration: a composite tool for managing patients with COPD

Clinically important deterioration (CID) is a composite tool developed to measure COPD's progression. It is a promising concept that can improve treatment choices for COPD patients because it provides a more holistic assessment of their status in everyday clinical practice. The post hoc analysis of several trials that were important for improving COPD treatment provides increasing evidence of the importance of assessing CID. These retrospective evaluations suggest that dual bronchodilation should be preferred over a single bronchodilator if treatment aims to reduce a possible clinical deterioration of COPD. Should dual bronchodilation prove ineffective, evidence shows that triple therapy, including an inhaled corticosteroid, is effective in preventing CID, especially in the presence of high blood eosinophil counts. CID initially included changes in FEV1 ≥100 mL from baseline, an increase in total SGRQ score ≥4 units, or a moderate/severe exacerbation. These thresholds were chosen arbitrarily because they were considered clinically relevant. Therefore, this multidimensional tool is being improved by including outcomes and thresholds that consider the peculiarities of the COPD population and the duration of the assessment. However, at present, studies that have assessed the impact of CID on COPD are almost all retrospective. Therefore, prospective studies need to be conducted that allow the complete validation of this instrument and better define the most effective components in assessing the risk of deterioration of COPD.

One\u2010year clinically important deterioration and long\u2010term clinical course in Japanese patients with COPD: a multicenter observational cohort study

BackgroundChronic obstructive pulmonary disease (COPD) is a heterogeneous disease with a complex progression of many clinical presentations, and clinically important deterioration (CID) has been proposed in the Western studies as a composite endpoint of disease progression. The aim of this study was to investigate the relationships between 1-year CID and the following long-term clinical outcomes in Japanese patients with COPD who have been reported to have different characteristics compared to the Westerners.MethodsAmong Japanese patients with COPD enrolled in the Hokkaido COPD cohort study, 259 patients who did not drop out within the first year were analyzed in this study. Two definitions of CID were used. Definition 1 comprised ≥ 100 mL decrease in forced expiratory volume in 1 s (FEV1), ≥ 4-unit increase in St George’s Respiratory Questionnaire (SGRQ) score from baseline, or moderate or severe exacerbation. For Definition 2, the thresholds for the FEV1 and SGRQ score components were doubled. The presence of CID was evaluated within the first year from enrollment, and analyzed the association of the presence of CID with following 4-year risk of exacerbations and 9-year mortality.ResultsPatients with CID using Definition 1, but not any single CID component, during the first year had a significantly worse mortality compared with those without CID. Patients with CID using Definition 2 showed a similar trend on mortality, and had a shorter exacerbation-free survival compared with those without CID.ConclusionsAdoption of CID is a beneficial and useful way for the assessment of long-term disease progression and clinical outcomes even in Japanese population with COPD. The definition of CID might be optimized according to the characteristics of COPD population and the observation period for CID.

Treatment of COPD with Long-Acting Bronchodilators: Association Between Early and Longer-Term Clinically Important Improvement.

IntroductionThis post hoc analysis of the “Early MAXimization of bronchodilation for improving COPD stability” (EMAX) trial investigated whether patients achieving early clinically important improvement (CII) sustained longer-term improvements and lower risk of clinically important deterioration (CID).MethodsPatients were randomized to umeclidinium/vilanterol, umeclidinium, or salmeterol for 24 weeks. The patient-reported outcomes (PROs) Transition Dyspnea Index (TDI), Evaluating Respiratory Symptoms, St George’s Respiratory Questionnaire (SGRQ) and COPD Assessment Test (CAT) were assessed. CII, defined as attaining minimum clinically important differences (MCID) in ≥2 PROs, was assessed at Weeks 4, 12 and 24. CID was defined as a deterioration in CAT, SGRQ, TDI by the MCID and/or a moderate/severe exacerbation from Day 30.ResultsOf 2425 patients, 50%, 53% and 51% achieved a CII at Weeks 4, 12 and 24, respectively. Patients with a CII at Week 4 versus those without had significantly greater odds of achieving a CII at Weeks 12 and 24 (odds ratio: 5.57 [95% CI: 4.66, 6.66]; 4.09 [95% CI: 3.44, 4.86]). The risk of a CID was higher in patients who did not achieve a CII at Week 4 compared with patients who did (hazard ratio [95% CI]: 2.09 [1.86, 2.34]). Patients treated with umeclidinium/vilanterol versus either monotherapy had significantly greater odds of achieving CII at Weeks 4, 12 and 24.ConclusionAchieving a CII at Week 4 was associated with longer-term improvement in PROs and a reduced risk of deterioration. Further research is required to investigate the importance of an early response to treatment on the long-term disease course.

When to Use Initial Triple Therapy in COPD: Adding a LAMA to ICS/LABA by Clinically Important Deterioration Assessment.

PurposeTriple therapy versus dual therapy for chronic pulmonary obstructive disease (COPD) can reduce symptoms, limit the risk of acute exacerbations (AEs) as well as improve lung function. Currently, studies that feature clinically important deterioration (CID) as a composite endpoint to assess the need for treatment intensification for patients maintained on dual therapy remained to be scarce.Patients and MethodsThis study is a retrospective analysis (January 2014 to January 2018) of COPD patients that presented with moderate to severe AEs during the previous year with blood eosinophil counts ≥ 100 cells/μL. The first line of therapy included a combination of inhaled corticosteroid (ICS) and a long-acting β2 agonist (LABA). Composite CID was used in assessing the response to treatment after 24 weeks of therapy.ResultsThis study included 110 patients, of which 49 patients reportedly experienced CID. The most common events of CID include a decline in forced expiratory volume in 1 second (FEV1) ≥ 100 mL from baseline (25/49, 51%) and an increase in COPD Assessment Test (CAT) scores ≥ 2 (13/49, 26.5%); many of these patients respond to the addition of a long-acting muscarinic antagonist (LAMA). Seven patients (7/110, 6.3%) experienced moderate to severe exacerbations while undergoing treatment with ICS/LABA. Univariate and multivariate analyses have identified low baseline FEV1 (OR = 0.81, p = 0.004), high CAT score (OR = 1.89, p = 0.004), and the frequency of AE (OR = 19.86, p = 0.021) as independent predictors of CID. A baseline FEV1 of ≤42%, an initial CAT score ≥ 18, and AE ≥ 2 last year were considered the optimal cut-off values, which were identified via receiver operating characteristics (ROC) curve analysis.ConclusionTriple therapy (ICS/LABAs/LAMAs) may be considered as first-line treatment in patients experiencing more than 2 times moderate to severe AEs of COPD in the previous year and who have blood eosinophil counts ≥100 cells/μL, reduced lung function (FEV1 ≤ 42%), and more symptoms (CAT score ≥ 18).

Tiotropium/Olodaterol Delays Clinically Important Deterioration Compared with Tiotropium Monotherapy in Patients with Early COPD: a Post Hoc Analysis of the TONADO® Trials.

IntroductionSince chronic obstructive pulmonary disease (COPD) is a heterogeneous condition, a composite endpoint of clinically important deterioration (CID) may provide a more holistic assessment of treatment efficacy. We compared long-acting muscarinic antagonist/long-acting β2-agonist combination therapy with tiotropium/olodaterol versus tiotropium alone using a composite endpoint for CID. CID was evaluated overall and in patients with low exacerbation history (at most one moderate exacerbation in the past year [not leading to hospitalisation]), Global Initiative for Chronic Obstructive Lung Disease (GOLD) 2 patients and maintenance-naïve patients with COPD. We assessed whether early treatment optimisation is more effective with tiotropium/olodaterol versus tiotropium in delaying and reducing the risk of CID.MethodsData were analysed from 2055 patients treated with either tiotropium/olodaterol 5/5 μg or tiotropium 5 μg (delivered via Respimat®) in two replicate, 52-week, parallel-group, double-blind studies (TONADO® 1/2). CID was defined as a decline of at least 0.1 L from baseline in trough forced expiratory volume in 1 s, increase from baseline of at least 4 units in St. George’s Respiratory Questionnaire score, or moderate/severe exacerbation. Time to first occurrence of one of these events was recorded as time to first CID.ResultsOverall, treatment with tiotropium/olodaterol significantly increased the time to, and reduced the risk of, CID versus tiotropium (median time to CID 226 versus 169 days; hazard ratio [HR] 0.76 [95% confidence interval 0.68, 0.85]; P < 0.0001). Significant reductions were also observed in patients with low exacerbation history (241 versus 170; HR 0.73 [0.64, 0.83]; P < 0.0001), GOLD 2 patients (241 versus 169; 0.72 [0.61, 0.84]; P < 0.0001) and maintenance-naïve patients (233 versus 171; 0.75 [0.62, 0.91]; P = 0.0030).ConclusionIn patients with COPD, including patients with low exacerbation history, GOLD 2 patients and maintenance-naïve patients, tiotropium/olodaterol reduced the risk of CID versus tiotropium. These results demonstrate the advantages of treatment optimisation with tiotropium/olodaterol over tiotropium monotherapy.Trial RegistrationClinicalTrials.gov identifier: TONADO® 1 and 2 (NCT01431274 and NCT01431287, registered 8 September 2011).Graphic Electronic supplementary materialThe online version of this article (10.1007/s12325-020-01528-2) contains supplementary material, which is available to authorized users.

Clinically Important Deterioration Among Patients with Chronic Obstructive Pulmonary Disease (COPD) Treated with Nebulized Glycopyrrolate: A Post Hoc Analysis of Pooled Data from Two Randomized, Double-Blind, Placebo-Controlled Studies.

PurposeUsing a composite endpoint, pooled data from two 12-week Phase III placebo-controlled trials (GOLDEN 3, NCT02347761; GOLDEN 4, NCT02347774) were analyzed to determine whether glycopyrrolate inhalation solution (25 mcg and 50 mcg) administered twice daily (BID) via the eFlow® Closed System nebulizer (GLY) reduced the risk of clinically important deterioration (CID) in patients with moderate-to-very-severe COPD.MethodsCID was defined as ≥100-mL decrease from baseline in post-bronchodilator trough forced expiratory volume in one second (FEV1), or ≥4-unit increase in baseline St. George’s Respiratory Questionnaire (SGRQ) total score, or moderate/severe exacerbation. The relative treatment effect of GLY versus placebo on the odds of CID (any and by component endpoints) was expressed as the odds ratio (OR) and 95% confidence interval (CI). Subgroups categorized by age (<65/≥65 years), sex, smoking status (current/former), long-acting beta agonist (LABA) use, FEV1 (<50%/≥50%), and peak inspiratory flow rate (PIFR) (<60 L/min/≥60 L/min) were analyzed.ResultsCompared to placebo, GLY 25 mcg and 50 mcg BID over 12 weeks significantly reduced the risk of CID by 50% (OR: 0.50 [0.37–0.68]) and 40% (OR: 0.60 [0.44–0.80]), respectively. Subjects treated with GLY 25 mcg BID were 59% less likely to experience CID in FEV1 (OR: 0.41 [0.27–0.62]) and 48% less likely to perceive CID in health status (OR: 0.52 [0.37–0.73]). Statistically significant reductions were also observed at the higher dose. The incidence of moderate/severe exacerbations was low and comparable among the cohorts. GLY 25 mcg BID was significantly more effective than placebo (p<0.05) in preventing CID irrespective of age, smoking status, LABA use, COPD severity, or PIFR. Subjects <65 years (OR 0.45 [0.29–0.68]) and those with PIFR <60 L/min (OR 0.36 [0.20–0.67]) exhibited the largest benefit.ConclusionNebulized GLY over 12 weeks significantly reduced the risk of CID and provided greater short-term stability in patients with moderate-to-very-severe COPD.

Composite endpoints in COPD: clinically important deterioration in the UPLIFT trial

BackgroundAssessments of lung function, exacerbations and health status are common measures of chronic obstructive pulmonary disease (COPD) progression and treatment response in clinical trials. We hypothesised that a composite endpoint could more holistically assess clinically important deterioration (CID) in a COPD clinical trial setting.MethodsA composite endpoint was tested in a post hoc analysis of 5652 patients with Global Initiative for Chronic Obstructive Lung Disease (GOLD) 2–4 COPD from the 4-year UPLIFT study. Patients received tiotropium 18 μg or placebo.ResultsThe composite endpoint included time to first confirmed decrease in trough forced expiratory volume in 1 s (FEV1) ≥100 mL, confirmed increase in St. George’s Respiratory Questionnaire (SGRQ) total score ≥ 4 units, or moderate/severe exacerbation. Most patients (> 80%) experienced CID, with similar incidence among GOLD subgroups. Most confirmed trough FEV1 (74.6–81.6%) and SGRQ (72.3–78.1%) deteriorations were sustained across the study and in all GOLD subgroups. Patients with CID more frequently experienced subsequent exacerbation (hazard ratio [HR] 1.79; 95% confidence interval [CI] 1.67, 1.92) or death (HR 1.21; 95% CI 1.06, 1.39) by Month 6. CID was responsive to bronchodilator treatment.ConclusionsComposite endpoints provide additional information on COPD progression and treatment effects in clinical trials.Trial registrationClinicalTrials.gov NCT00144339.Graphical abstract

Benefits of glycopyrrolate/formoterol fumarate metered dose inhaler (GFF MDI) in improving lung function and reducing exacerbations in patients with moderate-to-very severe COPD: a pooled analysis of the PINNACLE studies

BackgroundThe Phase III PINNACLE studies assessed the efficacy and safety of glycopyrrolate/formoterol fumarate metered dose inhaler (GFF MDI), a dual long-acting bronchodilator for chronic obstructive pulmonary disease (COPD). Here we present a pre-specified pooled analysis of PINNACLE-1, PINNACLE-2, and PINNACLE-4.MethodsPINNACLE-1, -2, and -4 were multicenter, double-blind, randomized controlled trials that enrolled patients with moderate-to-very severe COPD, with no requirement for exacerbation history or a high symptom burden. Patients received GFF MDI 18/9.6 μg, glycopyrrolate (GP) MDI 18 μg, formoterol fumarate (FF) MDI 9.6 μg, or placebo MDI, twice-daily for 24 weeks. The primary endpoint of the pooled analysis was the change from baseline in morning pre-dose trough forced expiratory volume in 1 s (FEV1) at week 24. Secondary endpoints included COPD exacerbations and clinically important deterioration (CID). Adverse events were also assessed.ResultsThe pooled intent-to-treat population included 4983 patients; of these, 61.9% had a COPD assessment test (CAT) score ≥15, and 25.0% had experienced ≥1 moderate/severe exacerbation in the past year. At week 24, GFF MDI improved morning pre-dose trough FEV1 versus GP MDI (least squares mean [LSM] difference [95% confidence interval (CI)]: 59 mL [43, 75]), FF MDI (65 mL [48, 81]), and placebo MDI (146 mL [125, 166]); all p < 0.0001. GFF MDI reduced the risk of a moderate/severe exacerbation by 18% (p = 0.0168), 15% (p = 0.0628), and 28% (p = 0.0012) compared with GP MDI, FF MDI, and placebo MDI, respectively. In general, exacerbation risk reduction with GFF MDI versus comparators was greater in subgroups of symptomatic patients (CAT ≥15) and those who had an exacerbation history, than in the pooled intent-to-treat population. The risk of CID was also lower with GFF MDI versus GP MDI (23% decrease), FF MDI (17%), and placebo MDI (49%); all p < 0.0001. All treatments were well tolerated, with no unexpected safety signals.ConclusionsThis pooled analysis of the PINNACLE studies demonstrated that GFF MDI improved lung function and reduced the risk of exacerbations compared with monocomponents and placebo in patients with COPD. Exacerbation reductions with GFF MDI versus comparators were generally greater in patients with higher symptom burden and those with exacerbation history.Trial registrationClinicalTrials.gov NCT01854645, NCT01854658, and NCT02343458.

Glycopyrrolate/formoterol fumarate metered dose inhaler for maintenance-na\xefve patients with chronic obstructive pulmonary disease: a post-hoc analysis of the randomized PINNACLE trials

BackgroundGlycopyrrolate (GP)/formoterol fumarate (FF; GFF) metered dose inhaler is a fixed-dose combination dual bronchodilator for patients with chronic obstructive pulmonary disease (COPD); however, whether the efficacy in patients without current maintenance treatment is consistent with currently maintenance-treated patients is unclear.MethodsData from patients who were not maintenance-treated at screening (NMT) (n = 1943) and patients who were maintenance-treated at screening (MT) patients (n = 3040) receiving GFF, FF, GP, or placebo were pooled from the Phase III PINNACLE studies (NCT01854645, NCT01854658, NCT02343458) for post-hoc analysis. MT patients had received long-acting bronchodilators and/or inhaled corticosteroids in the 30 days prior to screening, and/or prior to randomization. NMT patients had received short-acting bronchodilators or no treatment. Outcomes included forced expiratory volume over 1 s (FEV1), clinically important deterioration (CID), rescue medication use, and safety.ResultsGFF provided significant lung function improvements at Week 24 versus placebo, GP, and FF for NMT patients, with pre-dose trough FEV1 treatment differences of 152 (117–188) mL, 73 (45–100) mL, and 56 (29–84) mL, respectively (least squares mean change from baseline versus comparators [95% CI]; all P < 0.0001). GFF reduced the risk of CID by 17–43% in NMT (P ≤ 0.0157) and 18–52% (P ≤ 0.0012) in MT patients compared with monotherapy and placebo, and reduced rescue medication use by 1.5 puffs/day over 24 weeks for both cohorts. Safety profiles for all cohorts were consistent with each other and the parent studies.ConclusionsNMT patients achieved better lung function with GFF versus monotherapy and placebo, without increased safety risk. Dual bronchodilator therapy may offer better outcomes than monotherapy for COPD patients when administered as first-line treatment.

Modified and simplified clinically important deterioration: multidimensional indices of short-term disease trajectory to predict future exacerbations in patients with chronic obstructive pulmonary disease

Background and aims:Various prediction indices based on the single time point observation have been proposed in chronic obstructive pulmonary disease (COPD), but little was known about disease trajectory as a predictor of future exacerbations. Our study explored the association between disease trajectory and future exacerbations, and validated the predictive value of the modified and simplified short-term clinically important deterioration (CID).Methods:This study was a multicenter, prospective observational study. Patients with COPD were recruited into our study and followed up for 18 months. The modified CID (CID-C) was defined as a decrease of 100 mL in forced expiratory volume in 1 second (FEV1), or suffering exacerbations, or increase of 2 units in COPD Assessment Test (CAT) during the first 6 months follow-up. Simplified CID was defined when excluding CAT from the CID-C model.Results:A total of 127 patients were enrolled in our final analysis. Compared with patients without exacerbations during the period of the 6th to the 18th month, patients with exacerbations were more likely to have frequent short-term exacerbations in the first 6 months (2.14 versus 0.21, p < 0.001). The short-term exacerbations were the best predictor for future exacerbations [odds ratio (OR): 13.25; 95% confidence interval: 5.62–34.67; p < 0.001], followed by the history of exacerbation before study entry, short-term changes in FEV1 and CAT. CID-C and Simplified CID were both significantly associated with exacerbations (OR: 7.14 and 9.74, both p < 0.001). The receiver operating characteristic curves showed that the Simplified CID had slightly better predictive capacity for future exacerbation than CID-C (0.754 versus 0.695, p = 0.02).Conclusion:Disease trajectory, including both the CID-C and the Simplified CID had significant predictive value for future exacerbations.

Long-term outcomes following first short-term clinically important deterioration in COPD

BackgroundChronic obstructive pulmonary disease (COPD) is characterized by varying trajectories of decline. Information regarding the prognostic value of preventing short-term clinically important deterioration (CID) in lung function, health status, or first moderate/severe exacerbation as a composite endpoint of worsening is needed. We evaluated post hoc the link between early CID and long-term adverse outcomes.MethodsCID was defined as ≥100 mL decrease in forced expiratory volume in 1 s (FEV1), ≥4-unit increase in St George’s Respiratory Questionnaire (SGRQ) score from baseline, and/or a moderate/severe exacerbation during enrollment in two 3-year studies. Presence of CID was assessed at 6 months for the principal analysis (TORCH) and 12 months for the confirmatory analysis (ECLIPSE). Association between presence (+) or absence (-) of CID and long-term deterioration in FEV1, SGRQ, future risk of exacerbations, and all-cause mortality was assessed.ResultsIn total, 2870 (54%; TORCH) and 1442 (73%; ECLIPSE) patients were CID+. At 36 months, in TORCH, CID+ patients (vs CID-) had sustained clinically significant worsening of FEV1 (- 117 mL; 95% confidence interval [CI]: - 134, - 100 mL; P < 0.001) and SGRQ score (+ 6.42 units; 95% CI: 5.40, 7.45; P < 0.001), and had higher risk of exacerbations (hazard ratio [HR]: 1.61 [95% CI: 1.50, 1.72]; P < 0.001) and all-cause mortality (HR: 1.41 [95% CI: 1.15, 1.72]; P < 0.001). Similar risks post-CID were observed in ECLIPSE.ConclusionsA CID within 6–12 months of follow-up was consistently associated with increased long-term risk of exacerbations and all-cause mortality, and predicted sustained meaningful loss in FEV1 and health status amongst survivors.Trial registrationNCT00268216; NCT00292552.

Preventing clinically important deterioration with single-inhaler triple therapy in COPD.

Clinically important deterioration (CID) is a novel composite end-point (lung function, health status, exacerbations) for assessing disease stability in patients with chronic obstructive pulmonary disease (COPD).We prospectively analysed CID in the FULFIL study. FULFIL (ClinicalTrials.gov NCT02345161; randomised, double-blind, double-dummy, multicentre study) compared 24 weeks of once daily, single-inhaler fluticasone furoate/umeclidinium/vilanterol (FF/UMEC/VI) 100/62.5/25 µg with twice daily budesonide/formoterol (BUD/FOR) 400/12 μg in patients aged ≥40 years with symptomatic advanced COPD (Global Initiative for Chronic Obstructive Lung Disease group D). A subset of patients received study treatment for up to 52 weeks. Time to first CID event was assessed over 24 and 52 weeks using two approaches for the health status component: St George's Respiratory Questionnaire and COPD assessment test. FF/UMEC/VI significantly reduced the risk of a first CID event by 47–52% versus BUD/FOR in the 24- and 52-week populations using both CID definitions (p<0.001).The median time to first CID event was ≥169 days and ≤31 days with FF/UMEC/VI and BUD/FOR, respectively. Only stable patients with no CID at 24 weeks demonstrated sustained clinically important improvements in lung function and health status at 52 weeks versus those who had experienced CID.Once daily, single-inhaler FF/UMEC/VI significantly reduced the risk of CID versus twice daily BUD/FOR with a five-fold longer period without deterioration.

Preventing Clinically Important Deterioration of COPD with Addition of Umeclidinium to Inhaled Corticosteroid/Long-Acting β2-Agonist Therapy: An Integrated Post Hoc Analysis.

IntroductionAssessing clinically important measures of disease progression is essential for evaluating therapeutic effects on disease stability in chronic obstructive pulmonary disease (COPD). This analysis assessed whether providing additional bronchodilation with the long-acting muscarinic antagonist umeclidinium (UMEC) to patients treated with inhaled corticosteroid (ICS)/long-acting β2-agonist (LABA) therapy would improve disease stability compared with ICS/LABA therapy alone.MethodsThis integrated post hoc analysis of four 12-week, randomized, double-blind trials (NCT01772134, NCT01772147, NCT01957163, NCT02119286) compared UMEC 62.5 µg with placebo added to open-label ICS/LABA in symptomatic patients with COPD (modified Medical Research Council dyspnea scale score ≥ 2). A clinically important deterioration (CID) was defined as: a decrease from baseline of ≥ 100 mL in trough forced expiratory volume in 1 s (FEV1), an increase from baseline of ≥ 4 units in St George’s Respiratory Questionnaire (SGRQ) total score, or a moderate/severe exacerbation. Risk of a first CID was evaluated in the intent-to-treat (ITT) population and in patients stratified by Global initiative for chronic Obstructive Lung Disease (GOLD) classification, exacerbation history and type of ICS/LABA therapy. Adverse events (AEs) were also assessed.ResultsOverall, 1637 patients included in the ITT population received UMEC + ICS/LABA (n = 819) or placebo + ICS/LABA (n = 818). Additional bronchodilation with UMEC reduced the risk of a first CID by 45–58% in the ITT population and all subgroups analyzed compared with placebo (all p < 0.001). Improvements were observed in reducing FEV1 (69% risk reduction; p < 0.001) and exacerbation (47% risk reduction; p = 0.004) events in the ITT population. No significant reduction in risk of a SGRQ CID was observed. AE incidence was similar between treatment groups.ConclusionSymptomatic patients with COPD receiving ICS/LABA experience frequent deteriorations. Additional bronchodilation with UMEC significantly reduced the risk of CID and provided greater short-term stability versus continued ICS/LABA therapy in these patients.FundingGlaxoSmithKline (study number: 202067).Plain Language SummaryPlain language summary available for this article.Electronic supplementary materialThe online version of this article (10.1007/s12325-018-0771-4) contains supplementary material, which is available to authorized users.

Indacaterol/glycopyrronium versus salmeterol/fluticasone in the prevention of clinically important deterioration in COPD: results from the FLAME study

BackgroundChronic 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.MethodsCID 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.ResultsIND/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.ConclusionsIND/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.Trial registrationClinicaltrials.gov NCT01782326.

Comparison of glycopyrronium versus tiotropium on the time to clinically important deteriorations in patients with COPD: a post-hoc analysis of randomized trials

Glycopyrronium is a once-daily, inhaled long-acting muscarinic antagonist (LAMA) demonstrating similar efficacy to inhaled tiotropium in patients with moderate-to-severe COPD; however, the benefit of LAMAs on COPD symptoms has been variable. COPD is a progressive disease in which many patients develop an acute or sustained deterioration. Data on the prevention of clinically important deteriorations (CID) using LAMAs are limited. A pooled analysis was performed on four Phase III trials (n = 2936) that compared the efficacy of glycopyrronium (n = 1859) with tiotropium (n = 1077). The primary endpoint was significant delay and/or reduction in the occurrence of CID. CID was defined as any of the following: ≥100 mL decrease from baseline in pre-dose forced expiratory volume in 1 second (FEV1), ≥4 point increase in St George’s Respiratory Questionnaire score or a moderate-to-severe COPD exacerbation occurring after the first dose of study medication. A sustained CID was a CID occurring on ≥2 consecutive visits 4 weeks apart or for ≥50% of all available subsequent visits. Baseline characteristics for the overall population were similar. Patients had moderate (62%) or severe (38%) COPD. Mean post-bronchodilator FEV1 was approximately 55% predicted, and mean FEV1 reversibility was 16.7 and 18.6% in the glycopyrronium and tiotropium groups, respectively. Both glycopyrronium and tiotropium significantly reduced time to CID and sustained CID versus placebo (p < 0.001). No statistically significant differences were found between the glycopyrronium and tiotropium treatment groups in time to CID or sustained CID. Glycopyrronium is effective in delaying time to clinically important deteriorations, with similar efficacy to tiotropium.

Indacaterol/glycopyrronium reduces the risk of clinically important deterioration after direct switch from baseline therapies in patients with moderate COPD: a post hoc analysis of the CRYSTAL study.

PurposeCOPD is a progressive disease characterized by exacerbations and a decline in health status and lung function. Clinically important deterioration (CID) is a composite endpoint used to evaluate treatment efficacy. This analysis evaluated the impact of a direct switch to once-daily indacaterol/glycopyrronium 110/50 µg (IND/GLY) from previous monotherapy with a long-acting β2-agonist (LABA) or long-acting muscarinic antagonist (LAMA) or with an LABA and an inhaled corticosteroid (LABA + ICS) on reducing CID.MethodsCRYSTAL was a 12-week, prospective, multicenter, randomized, open-label study conducted in clinical practice settings. Three definitions of CID (D1–D3) were used, including: 1) ≥100 mL decrease in trough forced expiratory volume in 1 second (FEV1), 2) ≥1 point decrease in transition dyspnea index (TDI) and/or ≥0.4 points increase in clinical COPD questionnaire score (CCQ), or 3) an acute moderate/severe exacerbation (AECOPD). In D1 and D2, either TDI or CCQ was evaluated along with FEV1 and AECOPD, whereas in D3, all 4 parameters were included. ClinicalTrials.gov number: NCT01985334.ResultsOf the 2,159 patients analyzed, 1,622 switched to IND/GLY and 537 continued their baseline treatments. The percentage of patients with a CID was significantly lower after a direct switch to IND/GLY versus LABA or LAMA using all 3 CID definitions (D1: odds ratio [OR] 0.41 [95% CI: 0.30–0.55]; D2: OR 0.41 [95% CI: 0.31–0.55]; D3: OR 0.39 [95% CI: 0.29–0.52]). Compared with LABA + ICS, IND/GLY also reduced the risk of CID (D1: OR 0.76 [95% CI: 0.56–1.02]; D2: OR 0.75 [95% CI: 0.56–1.00]; D3: OR 0.67 [95% CI: 0.51–0.89]).ConclusionIn this analysis, IND/GLY reduced the risk of a CID in moderate COPD patients after direct switch from LABA + ICS or LABA or LAMA in real-life clinical practice.

Indacaterol/glycopyrronium (IND/GLY) reduces the risk of clinically important deterioration (CID) in patients with moderate COPD: Results from the CRYSTAL study

Introduction: Decline in health status, lung function, and exacerbations are important determinants of disease progression of COPD patients (pts). CID has been proposed as a composite endpoint to evaluate COPD treatment effects. We report effect of IND/GLY on CID in pts with moderate COPD, after direct switch from LABA+ICS, or a LABA or a LAMA monotherapy. Methods: CRYSTAL, a 12-week, prospective, multicentre, randomised, open-label, pragmatic trial, evaluated the effect of IND/GLY or GLY after a direct switch from previous treatments in moderate COPD pts. CID was defined as a ≥100 mL decrease in trough FEV 1 or a ≥1 point decrease in transition dyspnoea index (TDI) or a ≥0.4 point increase in clinical COPD questionnaire (CCQ) score or a moderate/severe exacerbation. Results: Of 2,159 pts analysed in the IND/GLY treatment arms, 1,622 switched to IND/GLY and 537 continued their baseline treatment. The percentage of pts experiencing a CID was significantly lower in pts who switched to IND/GLY vs pts who continued on LABA+ICS, or on a LABA or a LAMA, using different CID definitions (Table) . Subgroup analyses according to different baseline characteristics were consistent with the overall results. Conclusion: Indacaterol/glycopyrronium significantly reduced the risk of CID in moderate COPD patients, after direct switch from LABA/ICS, or a LABA or a LAMA.
