Single inhaler extrafine triple therapy versus long-acting muscarinic antagonist therapy for chronic obstructive pulmonary disease (TRINITY): a double-blind, parallel group, randomised controlled trial

Risk trajectory of cardiovascular events after an exacerbation of chronic obstructive pulmonary disease: A systematic review and meta-analysis

BACKGROUND

Exacerbations of chronic obstructive pulmonary disease (COPD) are known to increase the risk of cardiovascular (CV) events and mortality. However, the temporal trend of this risk has not fully elucidated. This systematic review and meta-analysis aims to quantify the risk of CV events after COPD exacerbations over different time periods.

OBJECTIVES

To assess the temporal association between CV events, including acute coronary syndrome (ACS), heart failure (HF), acute cereberovascular events, arrhythmia and all-cause mortality after the onset of COPD exacerbations in the following timepoints: 1-30 and 31-180 days; 1-7, 8-14, 15-30, 31-180, 181-365 and >365 days.

METHODS

A comprehensive literature search was conducted in PubMed, Embase, Web of Science and Cochrane databases, identifying observational studies that reported CV outcomes following COPD exacerbations. Studies were included if they enrolled adults diagnosed with COPD and compared CV event rates during exacerbation and non-exacerbation periods (PROSPERO, CRD42024561490).

RESULTS

Sixteen studies with over 1.8 million participants were included. Our meta-analysis demonstrated a significantly increased risk of ACS, HF, cerebrovascular events and arrhythmia, with the highest magnitude of risk observed in the period 1-30 days following an exacerbation. This increased risk showed a decline in time points 31-180, 181-365 days and remained persistently higher for ACS even one year after an acute exacerbation. Notably, the risk of HF was found to be greater compared to the other CV outcomes.

CONCLUSION

COPD exacerbations significantly increase the risk of acute CV events, particularly within the first 30 days. Optimal strategies to reduce cardiopulmonary risk are needed.

Prevalence and Clinical Outcomes of Eosinophilic COPD in a Saudi Population: A Retrospective Study

Objective

This study assessed the prevalence of eosinophilic chronic obstructive pulmonary disease (COPD) among a selected Saudi population and examined its correlation with baseline characteristics, clinical outcomes, exacerbation risk, and current management.

Materials and Methods

This retrospective single-center study was conducted over a 2-year period. The patients were divided into two groups based on the blood eosinophil count at the time of diagnosis: eosinophilic COPD (≥300 cells/μl) and non-eosinophilic COPD (<300 cells/μl) groups.

Results

Overall, 156 patients were included, of which 76 (48.7%) and 80 (51.3%) patients belonged to the eosinophilic and non-eosinophilic COPD groups, respectively. There were no significant differences between both groups regarding age, gender, smoking status, coexisting morbidities, FEV1, FEV1/FVC, and COPD severity (for all, P >0.05). Besides, there were no significant differences between both groups regarding the frequency and numbers of exacerbations, emergency room visits, in-patient hospitalizations, and intensive care unit admissions (for all, P >0.05). Among patients with eosinophilic COPD, 64 patients (84.2%) were correctly receiving the triple therapy of long-acting β2 agonists + long-acting muscarinic antagonist + inhaled corticosteroids, whereas 4 patients (5.26%) were incorrectly receiving the dual therapy of long-acting β2 agonists + inhaled corticosteroids. Univariate regression analyses revealed that heart failure, GOLD 3 severity, use of triple therapy, and use of non-invasive ventilation were significantly correlated with a higher risk of COPD exacerbation. Conversely, higher FEV1 was significantly correlated with lower risk of COPD exacerbation. The eosinophilic COPD phenotype was not found to be a significant independent variable of COPD exacerbation.

Conclusion

This study found that among Saudi patients with COPD, there was no clinically important relationship between baseline blood eosinophil count and the rate of exacerbation.

Beclometasone Dipropionate/Formoterol Fumarate is Similarly Effective to Budesonide/Formoterol Fumarate in Chinese Patients with COPD: The FORSYYN Double-Blind, Randomised Study

The fixed-dose combination of beclometasone dipropionate/formoterol fumarate (BDP/FF) delivered via pressurised metered-dose inhaler (pMDI) has demonstrated efficacy in chronic obstructive pulmonary disease (COPD), in studies predominantly conducted in Caucasian adults. The current study evaluated the efficacy and safety of BDP/FF pMDI in Chinese patients with COPD, as part of registration for COPD in China. This double-blind, double-dummy, randomised, parallel-group study was conducted in patients with COPD of Chinese ethnicity aged ≥40 years. After a 4-week open-label budesonide/formoterol fumarate (BUD/FF) run-in period, patients were randomised to BUD/FF or BDP/FF for 24 weeks. The primary objective was to demonstrate non-inferiority of BDP/FF to BUD/FF in terms of change from baseline in pre-dose morning forced expiratory volume in 1 sec (FEV1) at Week 24 (i.e. the lower 95% CI limit of the difference was above the pre-defined non-inferiority margin of -0.07 L). Of 750 patients randomised (377 BDP/FF; 373 BUD/FF), 87.6% completed the study. The primary endpoint was met in both the per-protocol (adjusted mean difference -0.001 L [95% CI: -0.025, 0.022], non-inferiority p < 0.001) and intention-to-treat populations (-0.001 L [-0.024, 0.022]; non-inferiority p < 0.001). There were no statistically significant BDP/FF-BUD/FF differences for the secondary endpoints, and a similar proportion of patients had adverse events (BDP/FF, 51.7%; BUD/FF, 51.2%), with most mild/moderate in severity. In conclusion, BDP/FF pMDI was non-inferior to BUD/FF in terms of pre-dose morning FEV1, supported by a range of secondary endpoints. Both treatments were similarly tolerated. The study supports the use of BDP/FF pMDI in Chinese patients with COPD.

Eosinophilic inflammation: a key player in COPD pathogenesis and progression

BACKGROUND

Chronic Obstructive Pulmonary Disease (COPD) remains a significant public health challenge due to its high morbidity and mortality rates. Emerging research has identified eosinophilic inflammation as a crucial factor in the pathogenesis and exacerbation of COPD, warranting a detailed exploration of its underlying mechanisms and therapeutic implications.

OBJECTIVE

This review aims to elucidate the role of eosinophils in COPD, focusing on their contribution to airway remodeling, exacerbation frequency, and the inflammatory cascade.

METHODS

We conducted a comprehensive literature review of recent studies that discuss the pathophysiological role of eosinophils in COPD and the clinical outcomes associated with modulating eosinophilic activity.

RESULTS

Eosinophils contribute to COPD progression by releasing cytotoxic proteins and cytokines that intensify the inflammatory response and airway alterations. Targeting specific eosinophil-related cytokines with monoclonal antibodies or receptor antagonists may potentially reduce eosinophil counts, mitigate exacerbations, and improve patient outcomes.

CONCLUSION

Understanding eosinophilic involvement in COPD can facilitate the development of precision medicine approaches, offering more tailored and effective treatment options. Future research should continue to focus on the integration of eosinophil biomarkers in clinical practice to enhance therapeutic decisions and management strategies for COPD patients.

[Real-life utilization of fixed triple therapy in COPD: The Trilife study. Beclomethasone/formoterol/glycopyrronium triple fixed-dose therapy in extra-fine particles]

INTRODUCTION

The Trilife study describes the real-life use, in France, of the beclomethasone/formoterol/glycopyrronium triple fixed-dose combination in solution for inhalation, which is indicated as continuous treatment for moderate-to-severe chronic obstructive pulmonary disease.

METHODS

This prospective, non-interventional, multicentric study, involving hospital and office-based pulmonologists, evaluates the proportion of patients for whom the triple fixed combination was prescribed in compliance with the indication and dosage specified in the summary of product characteristics (SPC). Patients were followed for six months.

RESULTS

In a population of 346 patients, the prescription was compliant with the SPC for 75.1% of patients (95% confidence interval: [70.6; 79.7]). The only variable associated with compliance with SPC in multivariate analyses was smoking (P=0.019). The results also show improved patient adherence to treatment and improved clinical status in terms of moderate or severe exacerbations, dyspnea, quality of life and satisfaction with treatment.

CONCLUSION

Three quarters of the fixed triple combination prescriptions by French pulmonologists comply with the indication and dosage specified in the summary of product characteristics.

The relevance of eosinophils in chronic obstructive pulmonary disease: inflammation, microbiome, and clinical outcomes

Chronic obstructive pulmonary disease is caused by the inhalation of noxious particles such as cigarette smoke. The pathophysiological features include airway inflammation, alveolar destruction, and poorly reversible airflow obstruction. A subgroup of patients with chronic obstructive pulmonary disease has higher blood eosinophil counts, associated with an increased response to inhaled corticosteroids and increased biomarkers of pulmonary type 2 inflammation. Emerging evidence shows that patients with chronic obstructive pulmonary disease with increased pulmonary eosinophil counts have an altered airway microbiome. Higher blood eosinophil counts are also associated with increased lung function decline, implicating type 2 inflammation in progressive pathophysiology in chronic obstructive pulmonary disease. We provide a narrative review of the role of eosinophils and type 2 inflammation in the pathophysiology of chronic obstructive pulmonary disease, encompassing the lung microbiome, pharmacological targeting of type 2 pathways in chronic obstructive pulmonary disease, and the clinical use of blood eosinophil count as a chronic obstructive pulmonary disease biomarker.

Personalized COPD Care: The Future of Precision-Based Therapies

Chronic obstructive pulmonary disease (COPD) is a progressive respiratory illness characterized by long-standing respiratory symptoms and airflow limitation. It is a major contributor to respiratory disease-related deaths and currently ranked as the sixth leading cause of mortality in the United States. Approved pharmacological therapies for the stable disease primarily consist of inhaled short and long-acting bronchodilators, inhaled corticosteroids, azithromycin, and roflumilast. In recent years, significant progress has been made in the management of COPD through the identification of different COPD phenotypes and endotypes, which allows for a more personalized treatment approach. While earlier studies investigating targeted therapies were less promising, recent data on drugs targeting type 2 inflammatory pathways have shown promising results in carefully selected patients. In this article, we will review the available data on targeted therapies as well as the ongoing clinical studies of novel targeted therapies for COPD. Understanding and implementing these advancements hold promise for improving outcomes and quality of life for individuals living with COPD.

Effects of inhaled beclometasone dipropionate/formoterol fumarate/glycopyrronium vs. beclometasone dipropionate/formoterol fumarate and placebo on lung hyperinflation and exercise endurance in chronic obstructive pulmonary disease: a randomised controlled trial

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 < 0.001 for both). Adjusted mean differences vs. placebo for the key secondary endpoints were: 245 mL for dynamic IC (p < 0.001) and 69.2 s for exercise endurance time (nominal p < 0.001) with BDP/FF/G, and 96 mL (p = 0.053) and 70.1 s (nominal p < 0.001) with BDP/FF. Differences between BDP/FF/G and BDP/FF for resting and dynamic IC were 92 and 149 mL (p < 0.01 for both). All three treatments were generally well tolerated, with 27.3%, 25.3% and 19.0% of patients reporting adverse events with BDP/FF/G, BDP/FF and placebo, respectively, all mild or moderate.

CONCLUSIONS

In patients with COPD, BDP/FF/G provided significant and clinically relevant improvements vs. placebo and BDP/FF in static and dynamic hyperinflation, with an improvement vs. placebo in exercise endurance.

Triple Therapy in COPD in Real Life: Is It Better to Use Single or Multiple Inhalers?

Background: Today, single-inhaler ICS/LAMA/LABA (SITT) COPD therapies are available. It is unclear whether they are more effective than multiple-device triple therapies (MITT) in improving COPD outcomes. Methods: We retrospectively considered patients on SITT/MITT in 2019/2020 who were prescribed >7 packages of ICS/LABA/LAMA or ICS/LAMA (+LAMA). The two treatments were compared concerning systemic corticosteroids, antibiotics, salbutamol, antifungal prescriptions, and number of emergency room visits/hospitalizations (ERV/Hs). We studied 292 MITT patients (Group A) during 2019, switching to SITT in 2020, and 366 subjects (Group B) who took SITT during 2019, and 206 MITT individuals (Group C) in 2020. Results: ICS/LABA + LAMA (MITT) package use was 8.2 ± 4.2 and 7.85 ± 4 in 2019, switching to 11.2 ± 3.2 when patients shifted to SITT in 2020 (p = 0.0001). Group A MITT package use was lower than in SITT patients in 2019 (9.31 ± 2.71, p = 0.0001; Group B). Throughout 2020, Group C (10.3 ± 6.1 packs) adherence to ICS/LABA was similar to SITT adherence in Group A (p = 0.270), whereas LAMA package use (9.1 ± 5) was lower (p = 0.0038). Patients using systemic corticosteroids/antibiotics were fewer in SITT in 2020, compared to the MITT results in 2019. Subjects with fewer ERV/Hs were observed with SITT rather than with MITT. Particularly, 13.8% of patients needed ≥2 ERV/Hs when treated with SITT, whereas 19.2% needed ≥2 ERV/Hs with MITT in 2019 (p = 0.08). Multivariate analysis, adjusted for all confounding factors including treatment adherence, showed that MITT (vs. SITT) can have an increased risk of at least one ERV/H (subjects receiving MITT during 2019 passing to SITT in 2020, OR: 1.718 [1.010-2.924], p = 0.046; Group A/MITT/2019 vs. Group B/SITT/2019, OR: 1.650 [0.973-3.153], p = 0.056; Group C/MITT/2020 vs. Group B/SITT/2019, OR: 1.908 [1.018-3.577], p = 0.044). Conclusions: SITT therapy may promote treatment adherence more effectively, therefore, reducing COPD exacerbations better than MITT. A possible synergistic effect of ICS/LABA/LAMA intake with a single device might be another cause of SITT's greater efficacy.

Race-Based Pulmonary Function Testing Correction in COPD Inhaler Therapy Trials: A Systematic Review

Purpose

Race-based correction is widely utilized in clinical practice, but may contribute to overestimation of lung function, underdiagnoses in minority groups, and exclusion of minority groups from research trials. The aim of this systematic review is to examine the usage of race-based correction in pulmonary function testing (PFT) within chronic obstructive lung disease (COPD) research and its impact on the exclusion of minority groups from research trials.

Methods

We systematically searched Medline from 2010 to 2022 to identify randomized controlled trials (RCTs) that examine inhaler therapy for COPD. Article screening, critical appraisal, and data extraction were completed in duplicate by independent reviewers. Data regarding study design, inclusion criteria, demographics, and race-based correction were extracted and synthesized narratively.

Results

Of the 774 screened articles, we included 21 RCTs in the review, which were multinational trials involving 70696 study participants. All studies had an inclusion criteria of an FEV1 cutoff of 50% to 80%. Racial minorities remained underrepresented in the trials, with the proportion of black participants ranging from <1% to 4.7%. Four studies directly mentioned race-based correction, while the remainder of the studies did not provide any explicit details. After obtaining additional information by contacting authors and reviewing the citations, 15 were estimated to utilize race-based correction.

Conclusion

Race-based correction may be frequently utilized in major COPD RCTs, but there remains inconsistent reporting regarding the usage of race-based correction. This may contribute to the exclusion of racialized populations from research trials as there remains significant underrepresentation of racialized populations from research.

Advances in inhaler therapy for asthma and chronic obstructive pulmonary disease: a comprehensive review of Fostair™ and Trimbow™

The management of asthma and chronic obstructive pulmonary disease (COPD) poses considerable challenges due to the intricate nature of these respiratory conditions. Fostair™ and Trimbow™, two pressurized metered dose inhalers, have emerged as noteworthy therapeutic options for treating both asthma and COPD. Fostair combines an inhaled corticosteroid, specifically beclometasone dipropionate, with a long-acting beta2-agonist, formoterol fumarate dihydrate, offering a dual-action approach to mitigate airway inflammation and bronchoconstriction. Conversely, Trimbow integrates a tri-particulate formulation consisting of beclometasone dipropionate, formoterol fumarate dihydrate, and glycopyrronium bromide, providing a comprehensive strategy to target the pathophysiology of COPD and asthma. Recent clinical trials have underscored Trimbow's superior efficacy compared with Fostair, particularly in terms of reducing exacerbation rates and enhancing lung function. However, despite their therapeutic promise, both inhalers encounter challenges, including limited generalizability of study findings and a disparity between in vitro and human trial results. This literature review offers an in-depth analysis of Fostair and Trimbow, delving into their mechanisms of action, clinical applications, and outcomes in human studies for asthma and COPD. Additionally, the review discusses the role of combination therapy in managing respiratory diseases and underscores the necessity for further research to address existing knowledge gaps and optimize therapeutic outcomes.

[COPD inhaled therapy narrative review]

The basis of COPD maintenance treatment is the long-acting bronchodilators and the inhaled corticosteroids. Faced with the recent modifications in the clinical practice guidelines, we have carried out a review of studies that contrast the various therapeutic alternatives and pharmacological agents within each category, with the fundamental purpose of shedding light on which of these options prove to be more effective. Triple therapy stands out as essential in poorly controlled patients or with an eosinophilic phenotype, surpassing dual therapy. However, among the combinations of LAMA/LABA or LAMA/LABA/IC, no drug is observed to be superior in the reviewed evidence. Although triple therapies include corticosteroids, there does not appear to be a significant increase in side effects or pneumonia. Regarding monotherapy with LAMA, no significant differences are seen between the drugs, but in dual therapy with LABA/IC, the budesonide/formoterol combination seems to offer better control than fluticasone/salmeterol.

An Italian Delphi Consensus on the Triple inhalation Therapy in Chronic Obstructive Pulmonary Disease

BACKGROUND

The management of chronic obstructive pulmonary disease (COPD) lacks standardization due to the diverse clinical presentation, comorbidities, and limited acceptance of recommended approaches by physicians. To address this, a multicenter study was conducted among Italian respiratory physicians to assess consensus on COPD management and pharmacological treatment.

METHODS

The study employed the Delphi process using the Estimate-Talk-Estimate method, involving a scientific board and expert panel. During a 6-month period, the scientific board conducted the first Delphi round and identified 11 broad areas of COPD management to be evaluated while the second Delphi round translated all 11 items into statements. The statements were subsequently presented to the expert panel for independent rating on a nine-point scale. Consensus was considered achieved if the median score was 7 or higher. Consistently high levels of consensus were observed in the first rating, allowing the scientific board to finalize the statements without requiring further rounds.

RESULTS

Topics generating substantial discussion included the pre-COPD phase, patient-reported outcomes, direct escalation from a single bronchodilator to triple therapy, and the role of adverse events, particularly pneumonia, in guiding triple therapy prescriptions. Notably, these topics exhibited higher standard deviations, indicating greater variation in expert opinions.

CONCLUSIONS

The study emphasized the significance that Italian pulmonologists attribute to managing mortality, tailoring treatments, and addressing cardiovascular comorbidities in COPD patients. While unanimous consensus was not achieved for all statements, the results provide valuable insights to inform clinical decision-making among physicians and contribute to a better understanding of COPD management practices in Italy.

AERIFY-1/2: two phase 3, randomised, controlled trials of itepekimab in former smokers with moderate-to-severe COPD

Background

Accumulating data implicate interleukin (IL)-33, a proinflammatory cytokine released locally upon epithelial cell damage, in the pathogenesis of COPD. In a phase 2 study, itepekimab, a human monoclonal antibody against IL-33, reduced exacerbations and improved lung function in a subgroup analysis of former smokers with COPD with an acceptable safety profile.

Methods

The study designs of AERIFY-1 and AERIFY-2 are described in this article.

Discussion

The primary objective of AERIFY-1/2 (NCT04701983/NCT04751487), two phase 3 randomised, double-blind, placebo-controlled trials, is to assess the efficacy and safety of itepekimab versus placebo in a population of former smokers with moderate-to-severe COPD over up to 52 weeks. An additional secondary population of current smokers are being enrolled in AERIFY-2. These two studies will enrol patients (aged 40-85 years) with COPD and chronic bronchitis who had ≥2 moderate or ≥ 1 severe exacerbations within the previous year despite standard-of-care triple or double background therapy. All participants are required to have ≥10-pack-year smoking history, and ≥6 months since smoking cessation for former smokers. The primary end-point is the annualised rate of moderate or severe acute exacerbation of COPD. Secondary end-points include change from baseline in pre- and post-bronchodilator forced expiratory volume in 1 s, and annualised frequency of severe exacerbations. Symptomatic end-points include Evaluating Respiratory Symptoms in COPD and St. George's Respiratory Questionnaire, safety and anti-drug antibody responses.

The Real-World Efficacy of Fixed Triple Inhalation Therapy in the Treatment of Moderate COPD Patients (RATIONALE Study)

Purpose

COPD affects more than 300 million people worldwide, requiring inhalation treatment. Novel triple formulations of ICS, LABAs and LAMAs are becoming the mainstay of treatment, however there is still a lack of clinical evidence for personalized therapy.

Patients and Methods

RATIONALE was a non-interventional, prospective, 52 week study, assessing the effectiveness of beclometasone/formoterol/glycopyrronium-bromide (BDP/FF/G), in symptomatic COPD patients, with moderate airflow obstruction. The study included 4 visits, where data on demographic parameters, exacerbations, symptoms, quality of life (based on the EQ-5D-3L questionnaire) and lung function were collected. Data on adherence to treatment, based on prescriptions filled was collected from the database of the National Health Insurance Fund, with the patients' consent. The primary objective was the change of adherence to treatment during the study, compared to baseline.

Results

Altogether 613 patients had been enrolled. Their average age was 64.56 years and 50.5% were female. The average CAT score was 20.86, and most patients had suffered minimum one exacerbation (82.2%). Average FEV1 was 59.6%. Most patients had some limitation in one or more dimensions of EQ-5D-3L, with an average visual analogue scale score (VAS) of 60.31. After 12 months of treatment, adherence improved significantly - proportion of patients in the highest adherence group increased from 29.8% to 69.7% (p<0.001). The average CAT score improved by 7.02 points (95% CI 5.82-8.21, p<0.001). There was a significant improvement in all dimensions of EQ-5D-3L, with an average increase of 17.91 (95% CI 16.51-19.31, p< 0.001) points in the VAS score. Exacerbation frequency also decreased significantly.

Conclusion

Although limitations of observational studies are present, we observed that early introduction of fixed triple combination results in a marked improvement in adherence to treatment, symptom scores, exacerbation frequency and quality of life. The optimal choice of treatment is crucial for reaching the highest possible adherence.

Intraclass comparison of inhaled corticosteroids for the risk of pneumonia in chronic obstructive pulmonary airway disorder: a network meta-analysis and meta-regression

BACKGROUND

Inhalational corticosteroids (ICS) were observed to increase the pneumonia risk in chronic obstructive pulmonary airway disorder (COPD). However, it is unknown whether any differences exist between the drugs within the ICS class.

AIM

This study aimed to evaluate the risk of pneumonia associated with different ICS and identify factors that predict pneumonia in patients with moderate-to-severe COPD using a network meta-analysis.

METHOD

Electronic databases (Medline, Cochrane CENTRAL and Google Scholar) were searched for trials comparing ICS in COPD patients. The outcomes were pneumonia and serious pneumonia. Odds ratios (OR) with 95% confidence interval (95% CI) were estimated. Meta-regression was used to identify the predictors. The strength of evidence was graded using the Grading of Recommendations, Assessment, Development, and Evaluations approach.

RESULTS

Sixty-six studies (103,347 participants) were included. Fluticasone (OR: 1.46; 95% CI: 1.26, 1.7), mometasone (OR: 2.2; 95% CI: 1.05, 4.6), and beclometasone (OR: 1.7; 95% CI: 1.1, 2.6) were observed with an increased pneumonia risk compared to placebo. Fluticasone (OR: 1.5; 95% CI: 1.3, 1.7) was observed with an increased risk of serious pneumonia. High doses (OR: 1.2; 95% CI: 1.03, 1.4), BMI ≥ 25 kg/m2 (OR: 1.6; 95% CI: 1.1, 2.2), and history of exacerbations in the preceding year predicted the pneumonia risk. Evidence strength was moderate.

CONCLUSION

ICS class differences in pneumonia risk were observed in terms of pooled effect estimates but it is unlikely that any clinically relevant differences exist. Risk-benefit analysis supports ICS use in moderate-severe COPD.

Adherence to single inhaler triple therapy and digital inhalers in Chronic Obstructive Pulmonary Disease: a literature review and protocol for a randomized controlled trial (TRICOLON study)

BACKGROUND

Medication non-adherence is a significant problem in patients with Chronic Obstructive Pulmonary Disease (COPD). Efforts to address this issue are receiving increased attention. Simplifying treatment by prescribing single-inhaler triple therapy (SITT) as an alternative to multi-inhaler triple therapy (MITT) or with smart inhalers are often considered potential solutions. However, the actual impact of these innovations on adherence and clinical outcomes is unclear.

METHODS

To address this knowledge gap we first conducted a literature review focusing on two research questions: 1) the difference in adherence between SITT and MITT users in COPD, and 2) the effect of smart inhalers on adherence in COPD. Separate searches were conducted in PubMed and two authors independently assessed the articles. In addition, we present a protocol for a study to acquire knowledge for the gaps identified.

RESULTS

To address the first research question, 8 trials were selected for further review. All trials were observational, i.e. randomized controlled trials were lacking. Seven of these trials showed higher adherence and/or persistence in patients on SITT compared with patients on MITT. In addition, four studies showed a positive effect of SITT on various clinical outcomes. For the second research question, 11 trials were selected for review. While most of the studies showed a positive effect of smart inhalers on adherence, there was considerable variation in the results regarding their effect on other clinical outcomes. The TRICOLON (TRIple therapy COnvenience by the use of one or multipLe Inhalers and digital support in ChrONic Obstructive Pulmonary Disease) trial aims to improve understanding regarding the effectiveness of SITT and smart inhalers in enhancing adherence. This open-label, randomized, multi-center study will enroll COPD patients requiring triple therapy at ten participating hospitals. In total, 300 patients will be randomized into three groups: 1) MITT; 2) SITT; 3) SITT with digital support through a smart inhaler and an e-health platform. The follow-up period will be one year, during which three methods of measuring adherence will be used: smart inhaler data, self-reported data using the Test of Adherence to Inhalers (TAI) questionnaire, and drug analysis in scalp hair samples. Finally, differences in clinical outcomes between the study groups will be compared.

DISCUSSION

Our review suggests promising results concerning the effect of SITT, as opposed to MITT, and smart inhalers on adherence. However, the quality of evidence is limited due to the absence of randomized controlled trials and/or the short duration of follow-up in many studies. Moreover, its impact on clinical outcomes shows considerable variation. The TRICOLON trial aims to provide solid data on these frequently mentioned solutions to non-adherence in COPD. Collecting data in a well-designed randomized controlled trial is challenging, but the design of this trial addresses both the usefulness of SITT and smart inhalers while ensuring minimal interference in participants' daily lives.

Small airways disease in chronic obstructive pulmonary disease

INTRODUCTION

Small airway disease (SAD) represents a common and critical feature of Chronic Obstructive Pulmonary Disease (COPD). Introduced in the '60s, SAD has gradually gained increasing interest as assessment methodologies have improved. Chronic exposure to smoking and noxious particles or gases induces inflammation and remodeling, leading to airway obstruction and SAD, eventually resulting in complete airway loss.

AREAS COVERED

A literature search up to June 2024 was performed in PubMed to identify articles on SAD and airway diseases mainly COPD, but also to the extent that it seemed relevant in the uncontrolled/severe asthma field, where SAD is better studied. We provide clinicians and translational scientists with a comprehensive analysis of the existing literature on SAD in COPD, concentrating on the underlying pathophysiological mechanisms, diagnostic techniques, and current pharmacological approaches targeting airflow obstruction in small airways.

EXPERT OPINION

Small airways are the primary site for the onset and progression of airflow obstruction in patients with COPD, with significant clinical consequences associated with poor lung function, hyperinflation, and impaired quality of life. The early identification of individuals with subclinical SAD may allow us to prevent its further progress from airway loss and potential development of emphysema and choose the appropriate therapeutic approach.

A clinician's guide to single vs multiple inhaler therapy for COPD

INTRODUCTION

In the management of chronic obstructive pulmonary disease (COPD), inhalation therapy plays a pivotal role. However, clinicians often face the dilemma of choosing between single and multiple inhaler therapies for their patients. This choice is critical because it can affect treatment efficacy, patient adherence, and overall disease management.

AREAS COVERED

This article examines the advantages and factors to be taken into consideration when selecting between single and multiple inhaler therapies for COPD.

EXPERT OPINION

Both single and multiple inhaler therapies must be considered in COPD management. While single inhaler therapy offers simplicity and convenience, multiple inhaler therapy provides greater flexibility and customization. Clinicians must carefully evaluate individual patient needs and preferences to determine the most appropriate inhaler therapy regimen. Through personalized treatment approaches and shared decision-making, clinicians can optimize COPD management and improve patient well-being. Nevertheless, further research is required to compare the effectiveness of single versus multiple inhaler strategies through rigorous clinical trials, free from industry bias, to determine the optimal inhaler strategy. Smart inhaler technology appears to have the potential to enhance adherence and personalized management, but the relative merits of smart inhalers in single inhaler regimens versus multiple inhaler regimens remain to be determined.

Post-traumatic stress disorder: the role of the amygdala and potential therapeutic interventions - a review

Introduction

Post-traumatic stress disorder (PTSD) is a psychiatric disorder triggered by exposure to a life-threatening or sexually violent traumatic event, and is characterized by symptoms involving intrusive re-experiencing, persistent avoidance of associated stimuli, emotional and cognitive disturbances, and hyperarousal for long periods after the trauma has occurred. These debilitating symptoms induce occupational and social impairments that contribute to a significant clinical burden for PTSD patients, and substantial socioeconomic costs, reaching approximately $20,000 dollars per individual with PTSD each year in the US. Despite increased translational research focus in the field of PTSD, the development of novel, effective pharmacotherapies for its treatment remains an important unmet clinical need.

Observations

In this review, we summarize the evidence implicating dysfunctional activity of the amygdala in the pathophysiology of PTSD. We identify the transient receptor potential canonical (TRPC) ion channels as promising drug targets given their distribution in the amygdala, and evidence from animal studies demonstrating their role in fear response modulation. We discuss the evidence-based pharmacotherapy and psychotherapy treatment approaches for PTSD.

Discussion

In view of the prevalence and economic burden associated with PTSD, further investigation is warranted into novel treatment approaches based on our knowledge of the involvement of brain circuitry and the role of the amygdala in PTSD, as well as the potential added value of combined pharmacotherapy and psychotherapy to better manage PTSD symptoms.

Implications of Cardiopulmonary Risk for the Management of COPD: A Narrative Review

Chronic obstructive pulmonary disease (COPD) constitutes a major global health burden and is the third leading cause of death worldwide. A high proportion of patients with COPD have cardiovascular disease, but there is also evidence that COPD is a risk factor for adverse outcomes in cardiovascular disease. Patients with COPD frequently die of respiratory and cardiovascular causes, yet the identification and management of cardiopulmonary risk remain suboptimal owing to limited awareness and clinical intervention. Acute exacerbations punctuate the progression of COPD in many patients, reducing lung function and increasing the risk of subsequent exacerbations and cardiovascular events that may lead to early death. This narrative review defines and summarises the principles of COPD-associated cardiopulmonary risk, and examines respiratory interventions currently available to modify this risk, as well as providing expert opinion on future approaches to addressing cardiopulmonary risk.

Evaluating the pharmacokinetics of beclometasone dipropionate/formoterol fumarate/glycopyrronium bromide delivered via pressurised metered-dose inhaler using a low global warming potential propellant

INTRODUCTION

Use of propellants with high global warming potential (such as HFA-134a) for pressurised metered-dose inhalers (pMDIs) is being phased down. Switching to dry-powder inhalers may not be clinically feasible for all patients; an alternative is reformulation using propellants with low global warming potential. The combination of beclometasone dipropionate/formoterol fumarate/glycopyrronium bromide (BDP/FF/GB) is available for asthma or chronic obstructive pulmonary disease via pMDI using HFA-134a as propellant. This is being reformulated using the low global warming potential propellant HFA-152a. This manuscript reports three studies comparing BDP/FF/GB pharmacokinetics delivered via pMDI using HFA-152a vs HFA-134a.

METHODS

The studies were four-way crossover, single-dose, randomised, double-blind, in healthy volunteers. In Studies 1 and 2, subjects inhaled four puffs of BDP/FF/GB (Study 1: 100/6/12.5 μg [medium-strength BDP]; Study 2: 200/6/12.5 μg [high-strength]), ingesting activated charcoal in two of the periods (once per propellant). In Study 3, subjects inhaled medium- and high-strength BDP/FF/GB using a spacer. All three studies compared HFA-152a vs HFA-134a in terms of lung availability and total systemic exposure of beclometasone-17-monopropionate (B17MP; active metabolite of BDP), BDP, formoterol and GB. Bioequivalence was concluded if the 90 % confidence intervals (CIs) of the ratios between formulations of the geometric mean maximum plasma concentration (Cmax) and area under the plasma concentration-time curve between time zero and the last quantifiable timepoint (AUC0-t) for the analytes were between 80 and 125 %.

RESULTS

In Studies 1 and 2, systemic exposure bioequivalence (i.e., comparisons without charcoal block) was demonstrated, except for GB Cmax in Study 2 (upper 90 % CI 125.11 %). For lung availability (i.e., comparisons with charcoal block), B17MP and formoterol demonstrated bioequivalence in both studies, as did BDP in Study 2; in Study 1, BDP upper CIs were 126.96 % for Cmax and 127.34 % for AUC0-t). In Study 1, GB AUC0-t lower CI was 74.54 %; in Study 2 upper limits were 135.64 % for Cmax and 129.12 % for AUC0-t. In Study 3, the bioequivalence criteria were met for BDP, B17MP and formoterol with both BDP/FF/GB strengths, and were met for GB AUC0-t, although not for Cmax. Both formulations were similarly well tolerated in all three studies.

CONCLUSIONS

Overall, while formal bioequivalence cannot be concluded for all analytes, these data suggest therapeutic equivalence of the new formulation with the existing BDP/FF/GB pMDI formulation, therefore supporting reformulation using a propellant with low global warming potential.

De-Prescribing Inhaled Corticosteroids in Chronic Obstructive Pulmonary Disease: A Narrative Review

Objective: Combination therapy, including inhaled corticosteroids (ICS), is often prescribed as initial treatment for Chronic Obstructive Pulmonary Disease (COPD) despite limited evidence that ICS therapy is beneficial. Prescribing rates exceed the estimated number of candidates diagnosed with COPD who are eligible for ICS treatment per guideline-directed therapy. Therefore, some patients would benefit from ICS withdrawal due to potentially inappropriate prescribing. This review aims to highlight evidence evaluating ICS withdrawal approaches in COPD. Methods: A comprehensive literature review was performed between June 2021 and March 2022 with assistance from a reference librarian. Sources of literature review include PubMed and Embase. The authors selected randomized controlled trials and articles evaluating ICS withdrawal approaches in patients with COPD. Three clinical trials and one post-hoc analysis are discussed in this review. Pertinent safety, efficacy, and statistical and clinical outcomes are summarized. Conclusions: The most appropriate approach to de-prescribe ICS maintenance therapy in COPD without clear indication remains uncertain. Pharmacists can play a role in optimizing clinical outcomes by analyzing ICS use in practice and identifying potential candidates for ICS withdrawal. The withdrawal protocols discussed in this review offer options for clinicians to help guide therapy decisions.

Effects of triple therapy on disease burden in patients of GOLD groups C and D: results from the observational COPD cohort COSYCONET

BACKGROUND

Randomized controlled trials described beneficial effects of inhaled triple therapy (LABA/LAMA/ICS) in patients with chronic obstructive pulmonary disease (COPD) and high risk of exacerbations. We studied whether such effects were also detectable under continuous treatment in a retrospective observational setting.

METHODS

Data from baseline and 18-month follow-up of the COPD cohort COSYCONET were used, including patients categorized as GOLD groups C/D at both visits (n = 258). Therapy groups were defined as triple therapy at both visits (triple always, TA) versus its complement (triple not always, TNA). Comparisons were performed via multiple regression analysis, propensity score matching and inverse probability weighting to adjust for differences between groups. For this purpose, variables were divided into predictors of therapy and outcomes.

RESULTS

In total, 258 patients were eligible (TA: n = 162, TNA: n = 96). Without adjustments, TA patients showed significant (p < 0.05) impairments regarding lung function, quality of life and symptom burden. After adjustments, most differences in outcomes were no more significant. Total direct health care costs were reduced but still elevated, with inpatient costs much reduced, while costs of total and respiratory medication only slightly changed.

CONCLUSION

Without statistical adjustment, patients with triple therapy showed multiple impairments as well as elevated treatment costs. After adjusting for differences between treatment groups, differences were reduced. These findings are compatible with beneficial effects of triple therapy under continuous, long-term treatment, but also demonstrate the limitations encountered in the comparison of controlled intervention studies with observational studies in patients with severe COPD using different types of devices and compounds.

TRITRIAL: The Impact of Fixed Triple Therapy with Beclometasone/Formoterol/Glycopyrronium on Health Status and Adherence in Chronic Obstructive Pulmonary Disease in an Italian Context of Real Life

Purpose

The TRITRIAL study assessed the effects of beclometasone dipropionate/formoterol fumarate/glycopyrronium (BDP/FF/G) fixed combination in patients with chronic obstructive pulmonary disease (COPD) in a real-world setting, focusing on patient's experience and perspective through the use of patients reported outcomes.

Patients and Methods

TRITRIAL was a multicenter, prospective, observational study conducted on patients with moderate-severe COPD treated with BDP/FF/G fixed therapy for 12 months. The main objective was to evaluate the impact of BDP/FF/G on health status through the COPD Assessment Test (CAT) score. Additional assessments included adherence and satisfaction, measured by the TAI-10/12 questionnaire and a specifically designed eight-item questionnaire, quality of life through the EQ-5D-5L test, sleep quality through the COPD and Asthma Sleep Impact Scale (CASIS), as well as safety and disease-related outcomes.

Results

Data from 655 patients were analyzed in the study. The mean total CAT score significantly improved (from 22.8 at baseline to 18.1 at 6 months and 16.5 at 12 months; p < 0.0001), as well as all the eight CAT sub-items, which decreased on average by 0.5-0.9 points during the study. Adherence and usability of the inhaler also improved during the study, with a decrease in poor compliance (from 30.1% to 18.3%) and an increase in good compliance (from 51.8% to 58.3%) according to the TAI score. Patients also benefited from significantly improved quality of life (EQ Index from 0.70 to 0.80; EQ-5D VAS score from 55.1 to 63.1) and sleep quality (CASIS score from 41.1 to 31.8). Finally, patients reported a significant reduction in exacerbation during the study.

Conclusion

TRITRIAL showed that the BDP/FF/G fixed combination is effective and safe in patients with moderate-severe COPD and poorly controlled disease, improving patients' HRQoL, sleep quality, adherence and inhaler usability and reducing COPD symptoms and the risk of exacerbation in a real-life setting.

National Development in the Use of Inhaled Corticosteroid Treatment in Chronic Obstructive Pulmonary Disease: Repeated Cross-Sectional Studies from 1998 to 2018

Recommendations for the treatment of chronic obstructive pulmonary disease (COPD) have shifted towards a more restrictive use of inhaled corticosteroids (ICS). We aimed to identify the nationwide development over time in the use of ICS treatment in COPD. We conducted a register-based repeated cross-sectional study using Danish nationwide registers. On a yearly basis from 1998 to 2018, we included all patients in Denmark ≥ 40 years of age with an ICD-10 diagnosis of COPD (J44). Accumulated ICS use was calculated for each year based on redeemed prescriptions. Patients were divided into the following groups: No ICS, low-dose ICS, medium-dose ICS, or high-dose ICS. From 1998 to 2018, the yearly proportion of patients without ICS treatment increased (from 50.6% to 57.6%), the proportion of patients on low-dose ICS treatment increased (from 11.3% to 14.9%), and the proportion of patients on high-dose ICS treatment decreased (from 17.0% to 9.4%). We demonstrated a national reduction in the use of ICS treatment in COPD from 1998 to 2018, with an increase in the proportion of patients without ICS and on low-dose ICS treatment and a decrease in the proportion of patients on high-dose ICS treatment.

Risk of Pneumonia in Patients with COPD Initiating Fixed Dose Inhaled Corticosteroid (ICS) / Long-Acting Bronchodilator (LABD) Formulations Containing Extrafine Beclometasone Dipropionate versus Patients Initiating LABD Without ICS

Background

Combined ICS and long-acting bronchodilators (LABD) more effectively reduce COPD exacerbations than LABD therapy alone. Corticosteroid-related adverse effects, including pneumonia, limit ICS use. Previous data suggest this risk is lower for extrafine beclometasone (ef-BDP). We compared pneumonia risk among new users of fixed dose ICS/LABD formulations containing ef-BDP, versus patients initiating LABD without any ICS.

Methods

A propensity-matched historical cohort study design used data from OPCRD. COPD patients with ≥1 year of continuous data who initiated LABD or ICS/LABD formulations containing ef-BDP were matched. Primary outcome was time to pneumonia event, as treated, using either sensitive (physician diagnosed) or specific (physician diagnosed and x-ray or hospital admission confirmed) definitions, with non-inferiority boundary of 15%.

Results

23,898 COPD patients were matched, who were 68±11 years, 54.3% male and 56% current-smokers, while 43% were former-smokers. Initiation of ef-BDP/LABD was not associated with an increased risk of pneumonia versus LABD, for either a sensitive 0.89 (0.78-1.02), P = 0.08 or a specific 0.91 (0.78-1.05), P = 0.18 definition of pneumonia. The probability of remaining pneumonia free 1-year after ef-BDP/LABD was 98.4%, which was comparable to LABD at 97.7%, and was sustained up to 6 years of observation; non-inferiority criterion was met for both definitions. Initiation of ef-BDP/LABD was also associated with a reduced risk of developing LRTIs in the propensity matched cohort.

Conclusion

Risk of pneumonia when using ICS for the management of COPD reported in several randomised controlled trials may not be relevant with ef-BDP in a diverse real-world clinical population.

Eligibility of patients with chronic obstructive pulmonary disease for inclusion in randomised control trials investigating triple therapy: a study using routinely collected data

BACKGROUND

Randomised control trials (RCTs) with strict eligibility criteria can lead to trial populations not commonly seen in clinical practice. We described the proportion of people with chronic obstructive pulmonary disease (COPD) in England eligible for RCTs investigating treatment with triple therapy.

METHODS

MEDLINE and Clinicaltrials.gov were searched for RCTs investigating triple therapy and eligibility criteria for each trial were extracted. Using routinely collected primary care data from Clinical Practice Research Datalink Aurum linked with Hospital Episode Statistics, we defined a population of COPD patients registered at a general practice in England, who were ≥ 40 years old, and had a history of smoking. Inclusion date was January 1, 2020. Patients who died earlier or left the general practice were excluded. Eligibility criteria for each RCT was applied to the population of COPD patients and the proportion of patients meeting each trial eligibility criteria were described.

RESULTS

26 RCTs investigating triple therapy were identified from the literature. The most common eligibility criteria were post-bronchodilator FEV1% predicted 30-80%, ≥ 2 moderate/≥ 1 severe exacerbations 12-months prior, no moderate exacerbations one-month prior and no severe exacerbations three-months prior, and the use of maintenance therapy or ICS use prior to inclusion. After applying each RCT eligibility criteria to our population of 79,810 COPD patients, a median of 11.2% [interquartile range (IQR) 1.8-17.4] of patients met eligibility criteria. The most discriminatory criteria included the presence exacerbations of COPD and previous COPD related medication use with a median of 67.6% (IQR 8.5-73.4) and 63% (IQR 69.3-38.4) of COPD patients not meeting these criteria, respectively.

CONCLUSION

Data from these RCTs may not be generalisable to the wider population of people with COPD seen in everyday clinical practice and real-world evidence studies are needed to supplement trials to understand effectiveness in all people with COPD.

The clinical characteristics and outcomes of different inhaled therapies in chronic obstructive pulmonary disease patients with frequent cough

BACKGROUND

Cough is a common symptom in patients with chronic obstructive pulmonary disease (COPD). Patients with cough may exhibit various clinical characteristics and experience varying outcomes based on inhaled therapies they receive.

OBJECTIVES

This study aimed to explore the clinical characteristics and outcomes of various inhaled therapies in COPD patients with frequent cough.

METHODS

This was a multicenter, prospective cohort study. Of these patients, the median cough score in COPD assessment test (CAT) was two. Patients were classified into frequent cough group if they scored two or over in the first item of CAT and infrequent cough group otherwise. Patients with frequent cough were then divided into long-acting antimuscarinic (LAMA), long-acting beta2-agonist (LABA)/LAMA, inhaled corticosteroids (ICS)/LABA and ICS/LABA/LAMA groups. Minimum clinically important difference (MCID) (CAT scores decreased ≥2 from baseline) and the improvement of cough (cough score decreased ≥1 from baseline) were collected in the six-month follow-up. Frequent exacerbations (experiencing at least two exacerbations) were collected in the one-year follow-up.

RESULTS

Of 906 patients, 581 (64.1%) patients reported frequent cough at the initial visit. Frequent cough was associated with the current smokers and CAT scores (p < 0.05). The MCID showed no significant difference between frequent cough and infrequent cough groups in the follow-up. More patients with frequent cough experienced future frequent exacerbations compared to those with infrequent cough. After receiving inhaled therapies, 62% of patients with frequent cough got the cough improved. More patients with frequent cough treated with LABA/LAMA or ICS/LABA/LAMA attained MCID and fewer experienced exacerbations than those treated with LAMA or ICS/LABA (p < 0.05). The change in cough score showed no difference among various inhaled therapies in patients with frequent cough.

CONCLUSION

COPD patients with frequent cough were related to current smokers and higher CAT scores. These patients had a higher incidence of frequent exacerbations than those with infrequent cough. Patients with frequent cough who were treated with LABA/LAMA or ICS/LABA/LAMA were more likely to attain MCID and at a lower risk of exacerbation than those treated with LAMA or ICS/LABA.

Outcomes Following Initiation of Triple Therapy with Fluticasone Furoate/Umeclidinium/Vilanterol versus Multiple-Inhaler Triple Therapy Among Medicare Advantage with Part D Beneficiaries and Those Commercially Enrolled for Health Care Insurance in the United States

Purpose

Patients with chronic obstructive pulmonary disease (COPD) have been shown to benefit from triple therapy commonly delivered by multiple-inhaler triple therapy (MITT); however, the complexity of MITT regimens may decrease patient adherence. Fluticasone furoate/umeclidinium/vilanterol (FF/UMEC/VI), a once-daily single-inhaler triple therapy (SITT), became available in the United States (US) in 2017, but real-world data comparing outcomes for SITT versus MITT are currently limited. This study compared outcomes among patients with COPD initiating MITT versus SITT with FF/UMEC/VI who were either Medicare Advantage with Part D (MAPD) beneficiaries or commercial enrollees in the US.

Methods

Retrospective study using administrative claims data from the Optum Research Database for patients with COPD who initiated FF/UMEC/VI or MITT between September 1, 2017, and March 31, 2019 (index date: first pharmacy claim for FF/UMEC/VI cohort; earliest day of ≥30 consecutive days-long period of overlap in the day's supply of all triple therapy components for MITT cohort). COPD exacerbations, adherence to triple therapy, and all-cause and COPD-related health care resource utilization (HCRU) and costs were compared between FF/UMEC/VI and MITT initiators.

Results

In total, 4659 FF/UMEC/VI initiators and 9845 MITT initiators for the MAPD population, and 821 FF/UMEC/VI initiators and 1893 MITT initiators for the commercial population were included in the study. MAPD beneficiaries initiating FF/UMEC/VI had a significantly lower annual rate of severe exacerbations compared to MITT initiators (0.26 vs 0.29; p=0.014). They also had a significantly higher mean adherence (proportion of days covered) (0.51 vs 0.37; p<0.001) and significantly lower all-cause and COPD-related inpatient stays compared to MITT initiators ([32.02% vs 34.27%; p=0.017], [16.09% vs 17.72%; p=0.037]). Trends were similar among the commercial population, but the results were not statistically significant.

Conclusion

FF/UMEC/VI initiators had significantly fewer severe exacerbations, higher triple therapy adherence, and lower HCRU costs compared to MITT initiators for MAPD beneficiaries.

Extrafine single inhaler triple therapy effectiveness in COPD patients previously treated with multiple-inhaler triple therapy: the TRIWIN study

BACKGROUND

The extrafine single inhaler triple therapy (efSITT) containing beclomethasone dipropionate/formoterol fumarate/glycopyrronium 87/5/9 μg has proved to be efficacious in patients with chronic obstructive pulmonary disease (COPD) in randomized control trials.

OBJECTIVE

TRIWIN study evaluated the effectiveness of efSITT delivering beclomethasone dipropionate/formoterol fumarate/glycopyrronium 87/5/9 μg in COPD patients previously treated with multiple-inhaler triple therapy (MITT) in a real-world study in Greece.

DESIGN

Prospective, multicenter, observational, non-interventional study was conducted over 24 weeks.

METHODS

A total of 475 eligible patients had moderate-to-severe COPD, an indication for treatment with efSITT, and were symptomatic despite receiving MITT. COPD Assessment Test (CAT) score, pulmonary function parameters, use of rescue medication, and adherence to inhaler use were recorded at baseline (Visit 1), 3 (Visit 2), and 6 months (Visit 3) after treatment.

RESULTS

Mean CAT score decreased from 21.4 points at Visit 1, to 16.6 at Visit 2 and 15.1 at Visit 3 (p < 0.001 for all pair comparisons). At Visit 3, 79.8% of patients reached a CAT improvement exceeding minimal clinically important difference (⩾2), compared to baseline. Mean forced expiratory volume in 1 s (%pred.) increased from 55.4% at Visit 1 to 63.5% at the end of study period (p < 0.001), while mean forced vital capacity (%pred.) increased from 71.1% at Visit 1, to 76.7% at Visit 3 (p < 0.001). The mean Test of Adherence to Inhalers score increased from 42.5 to 45.3 and 46.3 points, for the three visits, respectively (p < 0.001 comparing Visits 1/2 and Visits 1/3; p = 0.006 comparing Visits 2/3). The percentage of patients showing good adherence rose from 33.7% at baseline to 58.3% at Visit 3. The percentage of patients using rescue medication during the last month dropped from 16.2% to 7.4% at the end of study period (p < 0.001). Pulmonary function parameters also improved.

CONCLUSION

The TRIWIN results suggest that extrafine beclomethasone dipropionate/formoterol fumarate/glycopyrronium is effective in improving health status, pulmonary function, and adherence and in reducing rescue medication use in COPD patients previously treated with MITT, in a real-world setting in Greece.

How inhaled corticosteroids target inflammation in COPD

Inhaled corticosteroids (ICS) are the most commonly used anti-inflammatory drugs for the treatment of COPD. COPD has been previously described as a "corticosteroid-resistant" condition, but current clinical trial evidence shows that selected COPD patients, namely those with increased exacerbation risk plus higher blood eosinophil count (BEC), can benefit from ICS treatment. This review describes the components of inflammation modulated by ICS in COPD and the reasons for the variation in response to ICS between individuals. There are corticosteroid-insensitive inflammatory pathways in COPD, such as bacteria-induced macrophage interleukin-8 production and resultant neutrophil recruitment, but also corticosteroid-sensitive pathways including the reduction of type 2 markers and mast cell numbers. The review also describes the mechanisms whereby ICS can skew the lung microbiome, with reduced diversity and increased relative abundance, towards an excess of proteobacteria. BEC is a biomarker used to enable the selective use of ICS in COPD, but the clinical outcome in an individual is decided by a complex interacting network involving the microbiome and airway inflammation.

Bayesian or frequentist: there is no question when comparing single-inhaler triple therapies via network meta-analysis. Focus on fluticasone furoate/umeclidinium/vilanterol fixed-dose combination in chronic obstructive pulmonary disease

OBJECTIVES

Single-inhaler triple therapies (SITTs) have never been directly compared in randomized controlled trials (RCTs) in chronic obstructive pulmonary disease (COPD). Cochrane recommends the Bayesian approach for indirect comparisons but a frequentist network meta-analysis (NMA) reported superiority of fluticasone furoate/umeclidinium/vilanterol (FF/UMEC/VI) over other SITT. We assessed the most appropriate inference method for NMA characterized by between-study heterogeneity on SITT in COPD.

METHODS

Bayesian and frequentist NMA were performed on RCTs investigating the effect of SITT on exacerbations and trough forced expiratory volume in the 1st second (FEV1) in COPD.

RESULTS

The included RCTs (ETHOS, FULFIL, IMPACT, KRONOS 200812) reported significant between-study heterogeneity (I2 > 99%, p < 0.001). The Bayesian random-effect NMA provided unbiased evidence that FF/UMEC/VI was not superior to other SITT on exacerbations and trough FEV1. The frequentist fixed-effect NMA indicated that FF/UMEC/VI was significantly (p < 0.05) more effective than other SITT, although results were affected by dispersion, asymmetry, and significant risk of bias. Frequentist random-effect NMA provided effect estimates rather similar but not equal to those of Bayesian approach.

CONCLUSION

Indirect comparison should be performed via Bayesian approach instead of frequentist inference with a fixed-effect model. Claiming the superiority of a specific medication over other therapies should be confirmed by findings originating from well-designed RCTs.

Admission blood eosinophil count, inpatient death and death at 1 year in exacerbating patients with COPD

BACKGROUND

Blood eosinophil counts have been studied in patients with stable chronic obstructive pulmonary disease (COPD) and are a useful biomarker to guide inhaled corticosteroid use. Less is known about eosinophil counts during severe exacerbation.

METHODS

In this retrospective study, 2645 patients admitted consecutively with COPD exacerbation across six UK hospitals were included in the study, and the clinical diagnosis was confirmed by a respiratory specialist. The relationship between admission eosinophil count, inpatient death and 1-year death was assessed. In a backward elimination, Poisson regression analysis using the log-link function with robust estimates, patients' markers of acute illness and stable-state characteristics were assessed in terms of their association with eosinopenia.

RESULTS

1369 of 2645 (52%) patients had eosinopenia at admission. Those with eosinopenia had a 2.5-fold increased risk of inpatient death compared with those without eosinopenia (12.1% vs 4.9%, RR=2.50, 95% CI 1.88 to 3.31, p<0.001). The same mortality risk with eosinopenia was seen among the subgroup with pneumonic exacerbation (n=788, 21.3% vs 8.5%, RR=2.5, 95% CI 1.67 to 2.24, p<0.001). In a regression analysis, eosinopenia was significantly associated with: older age and male sex; a higher pulse rate, temperature, neutrophil count, urea and C reactive protein level; a higher proportion of patients with chest X-ray consolidation and a reduced Glasgow Coma Score; and lower systolic and diastolic blood pressure measurements and lower oxygen saturation, albumin, platelet and previous admission counts.

DISCUSSION

During severe COPD exacerbation, eosinopenia is common and associated with inpatient death and several markers of acute illness. Clinicians should be cautious about using eosinophil results obtained during severe exacerbation to guide treatment decisions regarding inhaled corticosteroid use.

Evolving to a single inhaler extrafine LABA/LAMA/ICS - Inhalation technique and adherence at the heart of COPD patient care (TRIVOLVE)

OBJECTIVE

Incorrect inhaler use and poor treatment adherence have a negative impact on COPD outcomes. This multi-centre, single arm, non-interventional, phase IV study investigated whether inhalation technique, treatment adherence and patient outcomes change in patients who evolve from dual therapy or multiple inhaler triple therapy to single inhaler extrafine triple therapy (beclomethasone dipropionate (BDP, 87 μg), formoterol fumarate (FF, 5 μg) and glycopyrronium (G, 9 μg)) in combination with inhalation technique training.

METHODS

A total of 126 COPD patients were included in the per protocol set. Inhalation technique and treatment adherence were assessed at baseline and at two visits at approximately 3 and 6 months of treatment with extrafine BDP/FF/G. In addition, lung function, symptom score, patient satisfaction and exacerbations (exploratory) were followed up.

RESULTS

Before switching to single inhaler extrafine BDP/FF/G (baseline), any device errors and critical errors were detected for 28.8% and 9.6% of patients, respectively. After switching to BDP/FF/G, the percentage of patients with any device errors decreased to 14.0% (visit 2) and 16.3% (visit 3), without critical errors at the two follow-up visits. Treatment adherence increased from 67.5% at baseline to 75.8% (visit 2) and 80% (visit 3). In addition, lung function, symptom and patient satisfaction scores improved, whilst exacerbation rates substantially decreased.

CONCLUSIONS

This observational study demonstrates that in eligible COPD patients in a real-life setting, the switch from dual therapy or multiple inhaler triple therapy to single inhaler extrafine BDP/FF/G in combination with inhalation technique training is associated with improved inhalation technique and adherence.

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

Purpose

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.

Patients and Methods

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.

Results

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.

Conclusion

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 effect of inhaled extrafine beclometasone dipropionate/formoterol fumarate/glycopyrronium bromide on distal and central airway indices, assessed using Functional Respiratory Imaging in COPD (DARWiIN)

BACKGROUND

This study, in patients with symptomatic chronic obstructive pulmonary disease (COPD), explored switching therapy from non-extrafine high-dose inhaled corticosteroid/long-acting β2-agonist (ICS/LABA; fluticasone propionate/salmeterol [FP/SLM]) to extrafine medium-dose beclometasone dipropionate/formoterol fumarate dihydrate/glycopyrronium (BDP/FF/G), both via dry-powder inhaler. Functional Respiratory Imaging, a quantitative computed tomography method with 3D reconstructions of pulmonary anatomy, was used to assess airway geometry and lung function.

METHODS

Patients receiving a stable ICS/LABA regimen for ≥ 8 weeks were switched to FP/SLM 500/50 µg, one inhalation twice-daily (high-dose ICS) for 6 weeks. After baseline assessments (Visit 2 [V2]), therapy was switched to BDP/FF/G 100/6/10 µg, two inhalations twice-daily (medium-dose ICS) for 6 weeks, followed by V3. The primary endpoints were percentage changes in specific image-based airway volume (siVaw) and resistance (siRaw) from baseline to predose at V3 (i.e., chronic effects), assessed at total lung capacity (TLC) in central and distal lung regions. Secondary endpoints included siVaw and siRaw changes from pre-dose to post-dose at V2, and from pre-dose to post-dose at V3 at TLC (i.e., acute effects), and chronic and acute changes in siVaw and siRaw at functional residual capacity (FRC). Pre-dose forced expiratory volume in 1 s (FEV1) and COPD Assessment Test (CAT) were also assessed.

RESULTS

There were no significant changes in pre-dose siVaw or siRaw at TLC from baseline to V3, although at FRC there was a significant decrease in mean siRaw in the distal airways (- 63.6%; p = 0.0261). In addition, in the distal airways there were significant acute effects at TLC on mean siVaw and siRaw (siVaw: 39.8% and 62.6%; siRaw: - 51.1% and - 57.2%, V2 and V3, respectively; all p < 0.001) and at FRC at V2 (siVaw: 77.9%; siRaw: - 67.0%; both p < 0.001). At V3, the mean change in pre-dose FEV1 was 62.2 mL (p = 0.0690), and in CAT total score was - 3.30 (p < 0.0001).

CONCLUSIONS

In patients with symptomatic COPD receiving high-dose ICS/LABA, adding a long-acting muscarinic antagonist while decreasing the ICS dose by switching to medium-dose extrafine BDP/FF/G was associated with improved airway indices, especially in the distal airways, together with improvements in respiratory health status.

DElaying Disease Progression In COPD with Early Initiation of Dual Bronchodilator or Triple Inhaled PharmacoTherapy (DEPICT): A Predictive Modelling Approach

INTRODUCTION

Clinical studies demonstrate an accelerated decline in lung function in patients with moderate chronic obstructive pulmonary disease (COPD) (Global Initiative for Chronic Obstructive Lung Disease [GOLD] grade 2) versus severe and very severe COPD (GOLD grades 3 and 4). This predictive modelling study assessed the impact of initiating pharmacotherapy earlier versus later on long-term disease progression in COPD.

METHODS

The modelling approach used data on decline in forced expiratory volume in 1 s (FEV1) extracted from published studies to develop a longitudinal non-parametric superposition model of lung function decline with progressive impact of exacerbations from 0 per year to 3 per year and no ongoing pharmacotherapy. The model simulated decline in FEV1 and annual exacerbation rates from age 40 to 75 years in COPD with initiation of long-acting anti-muscarinic antagonist (LAMA)/long-acting beta2-agonist (LABA) (umeclidinium (UMEC)/vilanterol (VI)) or triple (inhaled corticosteroid (ICS)/LAMA/LABA; fluticasone furoate (FF)/UMEC/VI) therapy at 40, 55 or 65 years of age.

RESULTS

Model-predicted decline in FEV1 showed that, compared with 'no ongoing' therapy, initiation of triple or LAMA/LABA therapy at age 40, 55 or 65 years preserved an additional 469.7 mL or 236.0 mL, 327.5 mL or 203.3 mL, or 213.5 mL or 137.5 mL of lung function, respectively, by the age of 75. The corresponding average annual exacerbation rates were reduced from 1.57 to 0.91, 1.06 or 1.23 with triple therapy or to 1.2, 1.26 and 1.4 with LAMA/LABA therapy when initiated at 40, 55 or 65 years of age, respectively.

CONCLUSIONS

This modelling study suggests that earlier initiation of LAMA/LABA or triple therapy may have positive benefits in slowing disease progression in patients with COPD. Greater benefits were demonstrated with early initiation therapy with triple versus LAMA/LABA.

Serum IL-8 as a Determinant of Response to Phosphodiesterase-4 Inhibition in Chronic Obstructive Pulmonary Disease

Rationale: Phosphodiesterase-4 (PDE4) inhibitors have demonstrated increased efficacy in patients with chronic obstructive pulmonary disease who had chronic bronchitis or higher blood eosinophil counts. Further characterization of patients who are most likely to benefit is warranted. Objective: To identify determinants of response to the PDE4 inhibitor tanimilast. Methods: A PDE4 gene expression signature in blood was developed by unsupervised clustering of the ECLIPSE study dataset (ClinicalTrials.gov ID: NCT00292552; Gene Expression Omnibus Series ID: GSE76705). The signature was further evaluated using blood and sputum transcriptome data from the BIOMARKER study (NCT03004417; GSE133513), enabling validation of the association between PDE4 signaling and target biomarkers. Predictivity of the associated biomarkers against clinical response was then tested in the phase-2b PIONEER tanimilast study (NCT02986321). Measurements and Main Results: The PDE4 gene expression signature developed in the ECLIPSE dataset classified subgroups of patients associated with different PDE4 signaling in the BIOMARKER cohort with an area under the receiver operator curve of 98%. In the BIOMARKER study, serum IL-8 was the only variable that was consistently associated with PDE4 signaling, with lower levels associated with higher PDE4 activity. In the PIONEER study, the exacerbation rate reduction mediated by tanimilast treatment increased up to twofold in patients with lower IL-8 levels; 36% versus 18%, reaching statistical significance at ⩽20 pg/ml (P = 0.035). The combination with blood eosinophils ⩾150 μl-1 or chronic bronchitis provided further additive exacerbation rate reduction: 45% (P = 0.013) and 47% (P = 0.027), respectively. Conclusions: Using selected heterogeneous datasets, this analysis identifies IL-8 as an independent predictor of PDE4 inhibition, as tanimilast had a greater effect on exacerbation prevention in patients with chronic obstructive pulmonary disease who had lower baseline serum IL-8 levels. Testing of this biomarker in other datasets is warranted. Clinical trial registered with www.clinicaltrials.gov (NCT00292552 [Gene Expression Omnibus Series ID: GSE76705], NCT03004417 [GSE133513], and NCT02986321).

COPD treatment - a conceptual review based on critical endpoints

INTRODUCTION

Chronic obstructive pulmonary disease (COPD) is one of the main causes of death and disability worldwide. Many treatment options are now available, but criteria for choosing inhaled bronchodilators and inhaled corticosteroids have been under discussion. New trials have highlighted the role of patient`s characteristics, such as eosinophil count and exacerbation history, in selecting the most effective personalised treatment option.

METHODS

In this conceptual review, an in-depth rationale is developed with an integrative approach to COPD treatment, gathering data from the main clinical trials performed so far and that may provide support for actual GOLD 2023 recommendations.

RESULTS

According to the patient's characteristics and profile, different treatment options, including mono, dual and triple therapies, are presented in a diagram matrix, comparing their efficacy in terms of reduction of exacerbations and mortality risk.

DISCUSSION AND CONCLUSION

Eosinophil counts and past exacerbation profile may play equally relevant roles to predict the individual risk and the potential response to inhaled corticosteroids. Thus, a comprehensive approach considering these two predictors is needed to aid clinicians decide preventative actions and choice of a first-line or step-up treatment.

Clinical Concepts for Triple Therapy Use in Patients with COPD: A Delphi Consensus

Purpose

Role of triple therapy in chronic obstructive pulmonary disease (COPD) management is supported by growing evidence, but consensus is lacking on various aspects. We conducted a Delphi survey in respiratory experts on the effects of triple therapy on exacerbation reduction, early optimization, pneumonia risk, and mortality benefits in COPD management.

Methods

The study comprised 2-round online surveys and a participant meeting with 21 respiratory experts from 10 countries. The 31-statement questionnaire was prepared using Decipher software after literature review. Responses were recorded using Likert scale ranging from 1 (disagreement) to 9 (agreement) with a consensus threshold of 75%.

Results

All experts participated in both surveys and 14/21 attended participant meeting. Consensus was reached on 13/31 questions in first survey and 4/14 in second survey on: mortality benefits of triple therapy; comparable pneumonia risk between single inhaler triple therapy (SITT) and multiple inhaler triple therapy (81%); preference of SITT for patients with high eosinophil count (95%); exacerbation risk reduction and healthcare cost benefits with early initiation of SITT post exacerbation-related hospitalization (<30 days) (86%). No consensus was reached on first line SITT use after first exacerbation resulting in COPD diagnosis (62%).

Conclusion

This study demonstrated that there is consensus among experts regarding many of the key concepts about appropriate clinical use and benefits of triple therapy in COPD. More evidence is required for evaluating the benefits of early optimisation of triple therapy.

Effect of fracture risk in inhaled corticosteroids in patients with chronic obstructive pulmonary disease: a systematic review and meta-analysis

BACKGROUND

The fracture risk of patients with chronic obstructive pulmonary disease (COPD) treated with inhaled corticosteroids is controversial. And some large-scale randomized controlled trials have not solved this problem. The purpose of our systematic review and meta-analysis including 44 RCTs is to reveal the effect of inhaled corticosteroids on the fracture risk of COPD patients.

METHODS

Two reviewers independently retrieved randomized controlled trials of inhaled corticosteroids or combinations of inhaled corticosteroids in the treatment of COPD from PubMed, Embase, Medline, Cochrane Library, and Web of Science. The primary outcome was a fracture event. This study was registered at PROSPERO (CRD42022366778).

RESULTS

Forty-four RCTs were performed in 87,594 patients. Inhaled therapy containing ICSs (RR, 1.19; 95%CI, 1.04-1.37; P = 0.010), especially ICS/LABA (RR, 1.30; 95%CI, 1.10-1.53; P = 0.002) and triple therapy (RR, 1.49; 95%CI, 1.03-2.17; P = 0.04) were significantly associated with the increased risk of fracture in COPD patients when compared with inhaled therapy without ICSs. Subgroup analyses showed that treatment duration ≥ 12 months (RR, 1.19; 95%CI, 1.04-1.38; P = 0.01), budesonide therapy (RR, 1.64; 95%CI., 1.07-2.51; P = 0.02), fluticasone furoate therapy (RR, 1.37; 95%CI, 1.05-1.78; P = 0.02), mean age of study participants ≥ 65 (RR, 1.27; 95%CI, 1.01-1.61; P = 0.04), and GOLD stage III(RR, 1.18; 95%CI, 1.00-1.38; P = 0.04) were significantly associated with an increased risk of fracture. In addition, budesonide ≥ 320 ug bid via MDI (RR, 1.75; 95%CI, 1.07-2.87; P = 0.03) was significantly associated with the increased risk of fracture.

CONCLUSION

Inhalation therapy with ICSs, especially ICS/LABA or triple therapy, increased the risk of fracture in patients with COPD compared with inhaled therapy without ICS. Treatment duration, mean age of participants, GOLD stage, drug dosage form, and drug dose participated in this association. Moreover, different inhalation devices of the same drug also had differences in risk of fracture.

Targeting Type 2 Inflammation and Epithelial Alarmins in Chronic Obstructive Pulmonary Disease: A Biologics Outlook

Chronic obstructive pulmonary disease (COPD) is a complex, heterogeneous, progressive inflammatory airway disease associated with a significant impact on patients' lives, including morbidity and mortality, and significant healthcare costs. Current pharmacologic strategies, including first- and second-line therapies such as long-acting β2-agonists, long-acting muscarinic antagonists, inhaled corticosteroids, phosphodiesterase-4 inhibitors, and macrolides, provide relief to patients with COPD. However, many patients remain symptomatic, with persistent symptoms and/or acute exacerbations and progressive lung function loss. Although neutrophilic inflammation is the most common type of inflammation in COPD, 20-40% of patients with COPD exhibit type 2 inflammation, with roles for CD4+ (cluster of differentiation 4) T-helper cell type 1 cells, type 2 innate lymphoid cells, eosinophils, and alternatively activated macrophages. On the basis of the current limitations of available therapies, a significant unmet need exists in COPD management, including the need for targeted therapies to address the underlying pathophysiology leading to disease progression, such as type 2 inflammation, as well as biomarkers to help select the patients who would most benefit from the new therapies. Significant progress is being made, with evolving understanding of the pathobiology of COPD leading to novel therapeutic targets including epithelial alarmins. In this review, we describe the current therapeutic landscape in COPD, discuss unmet treatment needs, review the current knowledge of type 2 inflammation and epithelial alarmins in COPD, explore potential biomarkers of type 2 inflammation in COPD, and finally provide a rationale for incorporating therapies targeting type 2 inflammation and epithelial alarmins in COPD.

Rational use of inhaled corticosteroids for the treatment of COPD

Inhaled corticosteroids (ICS) are the mainstay of treatment for asthma, but their role in chronic obstructive pulmonary disease (COPD) is debated. Recent randomised controlled trials (RCTs) conducted in patients with COPD and frequent or severe exacerbations demonstrated a significant reduction (~25%) in exacerbations with ICS in combination with dual bronchodilator therapy (triple therapy). However, the suggestion of a mortality benefit associated with ICS in these trials has since been rejected by the European Medicines Agency and US Food and Drug Administration. Observational evidence from routine clinical practice demonstrates that dual bronchodilation is associated with better clinical outcomes than triple therapy in a broad population of patients with COPD and infrequent exacerbations. This reinforces guideline recommendations that ICS-containing maintenance therapy should be reserved for patients with frequent or severe exacerbations and high blood eosinophils (~10% of the COPD population), or those with concomitant asthma. However, data from routine clinical practice indicate ICS overuse, with up to 50-80% of patients prescribed ICS. Prescription of ICS in patients not fulfilling guideline criteria puts patients at unnecessary risk of pneumonia and other long-term adverse events and also has cost implications, without any clear benefit in disease control. In this article, we review the benefits and risks of ICS use in COPD, drawing on evidence from RCTs and observational studies conducted in primary care. We also provide a practical guide to prescribing ICS, based on the latest global treatment guidelines, to help primary care providers identify patients for whom the benefits of ICS outweigh the risks.

Real-World Experience of Treating Chronic Obstructive Pulmonary Disease with Triple Therapy

Background

Double-blind randomized controlled trials have compared patients with chronic obstructive pulmonary disease (COPD) taking triple therapy, which can improve lung function, dyspnea, and quality of life and reduce acute exacerbation and mortality, with those taking long-acting muscarinic antagonist/long-acting β2-agonist; however, the real-word treatment scenario may be different from that of a strict and well-designed study. The aim of our study was to assess long-term outcomes among patients with COPD who received triple therapy in real-world practice.

Methods

Data from Taiwan's National Health Insurance Research Database (NHIRD) from 2005 and 2016 were used to identify COPD patients who were over 40 years of age with diagnosis codes 490-492, 496 (ICD-9-CM) or J41-44 (ICD-10-CM). After matching for age, sex, and COPD exacerbations, COPD patients who did and did not receive triple therapy were enrolled in this study. Cox proportional regression was used to estimate the mortality risk between smoking status and COPD patients with and without triple therapy.

Results

A total of 19,358 patients with COPD who did or did not receive triple therapy were enrolled in this study. The prevalence rates of some comorbidities were higher among patients with COPD who received triple therapy than among those who did not receive triple therapy. These comorbidities included lung cancer, thoracic malignancies, bronchiectasis, and heart failure. The risk of mortality was higher among patients who received triple therapy than among those who did not receive triple therapy after matching for age, sex, and COPD exacerbations, with a crude hazard ratio, fully adjusted model hazard ratio and stepwise approach reduced hazard ratio of 1.568 (95% CI, 1.500-1.639), 1.675 (95% CI, 1.596-1.757), and 1.677 (95% CI, 1.599-1.76), respectively.

Conclusion

Over 5 years of observation, patients with COPD who received triple therapy did not show a survival benefit compared with those who did not receive triple therapy in a real-world scenario.

Pharmacological therapy for stable chronic obstructive pulmonary disease

In recent years, emphasis has shifted from preventing and treating chronic obstructive pulmonary disease (COPD) to early prevention, early treatment, and disease stabilization, with the main goal of improving patients' quality of life and reducing the frequency of acute exacerbations. This review summarizes pharmacological therapies for stable COPD.
