Efficacy of budesonide/glycopyrronium/formoterol metered dose inhaler in patients with COPD: post-hoc analysis from the KRONOS study excluding patients with airway reversibility and high eosinophil counts

Benefits of budesonide/glycopyrronium/formoterol fumarate dihydrate on lung function and exacerbations of COPD: a post-hoc analysis of the KRONOS study by blood eosinophil level and exacerbation history

BACKGROUND

Japanese guidelines recommend triple inhaled corticosteroid (ICS)/long-acting muscarinic antagonist (LAMA)/long-acting β2-agonist (LABA) therapy in patients with chronic obstructive pulmonary disease (COPD) and no concurrent asthma diagnosis who experience frequent exacerbations and have blood eosinophil (EOS) count ≥ 300 cells/mm3, and in patients with COPD and asthma with continuing/worsening symptoms despite receiving dual ICS/LABA therapy. These post-hoc analyses of the KRONOS study in patients with COPD and without an asthma diagnosis, examine the effects of fixed-dose triple therapy with budesonide/glycopyrronium/formoterol fumarate dihydrate (BGF) versus dual therapies on lung function and exacerbations based on blood EOS count - focusing on blood EOS count 100 to < 300 cells/mm3 - as a function of exacerbation history and COPD severity.

METHODS

In KRONOS, patients were randomized to receive treatments that included BGF 320/14.4/10 µg, glycopyrronium/formoterol fumarate dihydrate (GFF) 14.4/10 µg, or budesonide/formoterol fumarate dihydrate (BFF) 320/10 µg via metered dose inhaler (two inhalations twice-daily for 24 weeks). These post-hoc analyses assessed changes from baseline in morning pre-dose trough forced expiratory volume in 1 s (FEV1) over 12-24 weeks and moderate or severe COPD exacerbations rates over 24 weeks. The KRONOS study was not prospectively powered for these subgroup analyses.

RESULTS

Among patients with blood EOS count 100 to < 300 cells/mm3, least squares mean treatment differences for lung function improvement favored BGF over BFF in patients without an exacerbation history in the past year and in patients with moderate and severe COPD, with observed differences ranging from 62 ml to 73 ml across populations. In this same blood EOS population, moderate or severe exacerbation rates were reduced for BGF relative to GFF by 56% in patients without an exacerbation history in the past year, by 47% in patients with moderate COPD, and by 50% in patients with severe COPD.

CONCLUSIONS

These post-hoc analyses of patients with moderate-to-very severe COPD from the KRONOS study seem to indicate clinicians may want to consider a step-up to triple therapy in patients with persistent/worsening symptoms with blood EOS count > 100 cells/mm3, even if disease severity is moderate and there is no recent history of exacerbations.

Effect of different doses of Budesonide combined with Tiotropium bromide inhalation on elderly patients with chronic obstructive pulmonary disease

Objective

To explore the clinical effect of various doses of Budesonide combined with Tiotropium bromide in the treatment of elderly patients with chronic obstructive pulmonary disease (COPD).

Methods

Clinical data of elderly patients with COPD, admitted to Affiliated Hospital of Shaoxing University from April 2021 to February 2023, were retrospectively analyzed. Based on the dosage of Budesonide combined with Tiotropium bromide, patients were divided into Low-dose group (Budesonide = 1mg), Medium-dose group (Budesonide = 2mg), and High-dose group (Budesonide = 3mg). All groups were matched for age, gender, course of disease, and BMI. Patients treated with Tiotropium bromide alone were assigned to the Control group. The clinical effect, pulmonary function index level, symptom improvement, inflammatory factor index level and adverse reactions in all groups were analyzed and compared.

Results

A total of 88 patients were included in this study with 22 patients in each group. The total efficacy of Medium-dose (90.91%) and High-dose group (90.91%) was significantly higher than that of Low-dose group (63.64%) and the Control group (59.09%) (P<0.05). After the treatment, levels of pulmonary function, symptom improvement and inflammatory factors in the High-dose and the Medium-dose groups were better than those in the Low-dose group and the Control group. Pulmonary function, symptom improvement and levels of inflammatory factors was significantly better in the Low-dose group compared to the Control group (P<0.05).

Conclusions

Budesonide combined with tiotropium bromide is better than tiotropium bromide alone in the treatment of elderly patients with COPD. Compared with low (1mg) dosage, medium (2mg) and high (3mg) dosage of budesonide are more effective in improving lung function, alleviating symptoms, reducing inflammatory response,, and are not associated with increased rate of adverse reactions.

Bu-Fei Yi-Shen Granules Reduce Acute Exacerbations in Patients with GOLD 3-4 COPD: A Randomized Controlled Trial

Purpose

Chronic obstructive pulmonary disease (COPD) is a disease characterized by frequent acute exacerbations (AEs), especially in severe and very severe cases. We aimed to evaluate the efficacy and safety of Bu-fei Yi-shen granules (BYGs) for COPD.

Patients and Methods

We conducted a multicenter, randomized, double-blinded, placebo-controlled trial of 348 COPD patients with GOLD 3-4 COPD. The patients were randomly assigned into experimental or control groups in a 1:1 ratio. Patients in the experimental group were prescribed BYG, while those in the control group were administered a placebo, orally, twice daily, with 5 days on and 2 days off per week for 52 weeks. The outcomes included AEs, pulmonary function, clinical signs and symptoms, dyspnea scores (mMRC), quality of life scores, and a 6-minute walk test (6MWT).

Results

A total of 280 patients completed the trial, including 135 patients in the experimental group and 145 in the control group. Compared to the control group, significant differences were observed in frequencies of AEs (mean difference: -0.35; 95% CI: -0.61, -0.10; P = 0.006) and AE-related hospitalizations (-0.18; 95% CI: -0.36, -0.01; P = 0.04), 6MWD (40.93 m; 95% CI: 32.03, 49.83; P < 0.001), mMRC (-0.57; 95% CI: -0.76, -0.37; P < 0.001), total symptoms (-2.18; 95% CI: -2.84, -1.53; P < 0.001), SF-36 (11.60; 95% CI: 8.23, 14.97; P < 0.001), and mCOPD-PRO (-0.45; 95% CI: -0.57, -0.33; P < 0.001) after treatment. However, there were no significant differences in mortality, pulmonary function, and mESQ-PRO scores (P > 0.05). No obvious adverse events were observed.

Conclusion

BYG, as compared to a placebo, could significantly reduce the frequencies of AEs and AE-related hospitalizations for GOLD 3-4 COPD patients. Clinical symptoms, treatment satisfaction, quality of life, and exercise capacity improved. There was no significant improvement in mortality and pulmonary function.

Therapeutic Response to Single-Inhaler Triple Therapies in Moderate-to-Severe COPD

BACKGROUND

COPD is characterized by progressive and irreversible air flow limitations. Single-inhaler therapies (SITTs) incorporating an inhaled corticosteroid, a long-acting muscarinic antagonist, and a long-acting β2-agonist have been shown to effectively alleviate symptoms and improve lung function. Fluticasone-furoate/umeclidinium/vilanterol (F/U/V) and budesonide/glycopyrronium/formoterol (B/G/F) are available as SITT in Japan. However, the clinical differences between these 2 combinations and the predictors of their proper use have not been established. This study aimed to identify the subject characteristics that could predict the effectiveness of inhaler therapy.

METHODS

We assessed the pulmonary function test results of subjects with COPD before and one month after using F/U/V and B/G/F as SITT. Subjects with a difference of 100 mL or more in the FEV1 after treatment with pre-SITT were extracted and divided into the F/U/V effect and no-effect group and B/G/F effect and no-effect group to examine the factors associated with positive outcomes with each inhaler.

RESULTS

F/U/V and B/G/F significantly improved the inspiratory capacity (IC), %IC, FVC, and %FEV1 when compared to pre-intervention values (P < .001, P = .001, P = .007, P = .009, respectively, for F/U/V; and P = .006, P = .008, P = .038, P = .005, respectively, for B/G/F). Factors associated with FEV1 improvement in F/U/V included lower %IC (odds ratio 0.97 [95% CI 0.94-0.99], P = .03) and a higher modified Medical Research Council (mMRC) dyspnea score (2.36 [1.27-4.70], P < .01). In addition, a higher %IC (1.03 [1.00-1.06], P = .02) and lower mMRC dyspnea score (0.55 [0.28-0.99], P = .041) were predictors for the effectiveness of B/G/F.

CONCLUSIONS

Our results showed that SITT significantly improved the IC, %IC, FVC, and %FEV1 when compared to pre-intervention and that F/U/V was more effective in subjects with severe symptoms, whereas B/G/F was more effective in subjects with mild symptoms.

The Efficacy and Safety of Budesonide/Glycopyrronium/Formoterol in the Treatment of COPD in the Elderly

Objective

Chronic obstructive pulmonary disease (COPD) is a major and difficult disease of the chronic respiratory system that is common and frequent, with a huge disease burden. The aim of this study was to investigate the efficacy and safety of budesonide/glyburide/formoterol fumarate (BGF) in the treatment of COPD.

Methods

A comprehensive literature search was conducted in PubMed, Embase, Cochrane Library, and Web of Science. The basic features of the seven pieces of literature were identified using the search strategy. The sample size range was 130∼1264.

Results

The effects of BGF increased FEV1 in patients with COPD (mean difference = 2.86, 95%CI: 2.71–3.01, p < 0.00001). The effects of BGF improved in patients with ≥1 TEAE in patients with COPD, and was not statistically significant after treatment (Odds rate = 1.00, 95%CI: 0.85–1.17, p=0.97). The effects of BGF increased in patients with TEAEs related a to study treatment in patients with COPD (odds rate = 1.27, 95% CI: 1.03–1.57, p=0.02). The effects of BGF in decreased patients with serious TEAEs in patients with COPD (odds rate = −0.02, 95% CI: −0.03–−0.00, p=0.04). The effects of BGF decreased the death rate in patients with COPD, and were not statistically significant after treatment (odds rate = 0.77, 95% CI: 0.31–1.97, p=0.59). The effects of BGF decreased the hypertension rate in patients with COPD (odds rate = 0.92, 95% CI: 0.44–1.89, p=0.81), and was not statistically significant after treatment. The effects of BGF increased pneumonia in patients with COPD (odds rate = 1.55, 95% CI: 0.81–2.97, p=0.19), and were not statistically significant after treatment. The effects of BGF increased FEV1, increased patients with TEAEs related a to study treatment, and decreased patients with serious TEAEs in patients with COPD.

Conclusion

This study elucidates the efficacy and safety of BGF in the treatment of COPD with a view to providing a clinical reference.

Budesonide/Glycopyrrolate/Formoterol Fumarate Co-suspension Metered Dose Inhaler: A Triple Therapy for the Treatment of Chronic Obstructive Pulmonary Disease

OBJECTIVE

To review current evidence on the use of a fixed-dose combination (FDC) of budesonide/glycopyrrolate/formoterol fumarate (BGFF) triple therapy delivered via metered dose inhaler (MDI) in patients with chronic obstructive pulmonary disease (COPD) and offer clinical practice insights.

DATA SOURCES

We used PubMed to conduct the literature search from 1946 through June 30, 2021, using budesonide, glycopyrrolate or glycopyrronium, and formoterol.

STUDY SELECTION AND EXTRACTION

We included clinical trials in patients with COPD along with pharmacokinetic or pharmacodynamic studies.

DATA SYNTHESIS

In all, 19 citations were included. BGFF MDI reduces the risk of exacerbations regardless of exacerbation history compared with dual bronchodilators or inhaled corticosteroid/long-acting β-agonist. Rescue inhaler use decreased, and patient-reported outcomes of symptoms and well-being improved with triple therapy. Mortality was decreased with the higher-dose BGFF MDI in comparison to dual bronchodilator therapy. Dysphonia and candidiasis were more common with BGFF MDI compared with dual bronchodilators, as was pneumonia.

RELEVANCE TO PATIENT CARE AND CLINICAL PRACTICE

BGFF MDI is the second FDC triple therapy approved for COPD treatment. BGFF MDI improves important patient outcomes in COPD, including exacerbation risk. The unique co-suspension technology allows delivery of 3 active ingredients in 1 inhaler, a potential benefit to overcome adherence and technique-related barriers. These benefits must be gently weighed against the increased risk of pneumonia.

CONCLUSION

The findings from phase 3 trials support the efficacy and safety of triple therapy in COPD. Future studies are needed to confirm potential mortality benefit and the role of triple therapy in patients without an exacerbation history.
