Comparative effectiveness and safety of inhaled corticosteroid plus long-acting ß2-agonist fixed-dose combinations vs. long-acting muscarinic antagonist in bronchiectasis.

BACKGROUND: This study aimed to evaluate the effectiveness and safety of fixed-dose combination (FDC) inhaled corticosteroids/long-acting ß2-agonists (ICS/LABA) in bronchiectasis. RESEARCH DESIGN AND METHODS: A retrospective cohort study analyzed electronic medical records of bronchiectasis patients initiating ICS/LABA FDC or LAMA between 2007 and 2021. All bronchiectasis diagnoses were made by radiologists using high-resolution computed tomography. RESULTS: Of the 1,736 patients, 1,281 took ICS/LABA FDC and 455 LAMA. Among the 694 propensity score matched patients, ICS/LABA FDC had comparable outcomes to LAMA, with HRs of 1.22 (95% CI 0.81-1.83) for hospitalized respiratory infection, 1.06 (95% CI 0.84-1.33) for acute exacerbation, and 1.06 (95% CI 0.66-1.02) for all-cause hospitalization. Beclomethasone/formoterol (BEC/FOR) or budesonide/formoterol (BUD/FOR) led to a lower risk of acute exacerbation compared to fluticasone/salmeterol (FLU/SAL) (BEC/FOR HR 0.59, 95% CI 0.43-0.81; BUD/FOR HR 0.68, 95% CI 0.50-0.93). BEC/FOR resulted in lower risks of hospitalized respiratory infection (HR 0.48, 95% 0.26-0.86) and all-cause hospitalization (HR 0.55, 95% 0.37-0.80) compared to FLU/SAL. CONCLUSION: Our findings provide important evidence on the effectiveness and safety of ICS/LABA FDC compared with LAMA for bronchiectasis. BEC/FOR and BUD/FOR were associated with better outcomes than FLU/SAL.

Dupilumab suppresses relapsing chronic eosinophilic pneumonia with severe asthma.

Dupilumab-induced hypereosinophilia is mediated by blockade of the IL-4/IL-13 pathway, which reduces eosinophil migration from peripheral blood. The increase in peripheral blood eosinophils may lead to chronic eosinophilic pneumonia (CEP) and/or eosinophilic granulomatosis with polyangiitis, but a direct causal connection between dupilumab and eosinophilic lung diseases has not been established. A 33-year-old Japanese woman with bronchial asthma since age three was treated with fluticasone propionate plus salmeterol twice daily after several asthma exacerbations at age 17. Her course was complicated by CEP at age 33 which resolved without the need for systemic steroids. However, in the four months following resolution of her CEP, the patient had three asthma exacerbations, and a recurrence of CEP, with blood leukocytes of 8500/µL, of which 25.0% were eosinophils. She was treated with prednisolone 50 mg/day, but she could not continue this dose due to the onset of myalgia. Then she had relapsing CEP twice within three months. She was treated with prednisolone 15 mg/day for CEP, but she had persistent asthma for more than one month; dupilumab was added at 600 mg, followed by 300 mg every two weeks. In the first month of treatment with dupilumab, the patient's asthma symptoms resolved completely, and she had only one relapse of CEP. In 12 months of follow-up, she had neither an asthma exacerbation nor another relapse of CEP. Dupilumab may be a promising treatment for patients with refractory asthma complicated by recurring CEP and undesirable steroid side effects.

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 ß2-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.

Consultas a urgencia y valores espirométricos tras el reemplazo de salmeterol/fluticasona por budesonida/formoterol en pacientes con asma moderada a grave / Emergency consultations and spirometric values after replacement of salmeterol/fluticasone with budesonide/formoterol in patients with moderate to severe asthma

El asma se caracteriza por su impacto deletéreo que incluye gran coste económico para el sistema de salud. En pacientes con asma mal controlada a pesar del tratamiento, se propone un régimen de mantenimiento con corticoides inhalados y formoterol. El objetivo del presente estudio observacional retrospectivo fue evaluar las modificaciones espirométricas tras el cambio del medicamento controlador en pacientes con asma moderada a severa asistidos en el Hospital Clínico de Magallanes de Punta Arenas, así como también cuantificar la modificación en el número de exacerbaciones graves (consulta a un servicio de urgencia y/u hospitalización por asma). Participaron 61 adultos con asma moderada a severa (mediana de edad: 60 años [rango: 21-87], mujeres: 69,4%; comorbilidad atópica/alérgica: 79%; otras comorbilidades: 46,8%) en los que se cambió el tratamiento con fluticasona/salmeterol 250/25 μg por budesónida/formoterol 160/4,5 μg. No se observaron cambios significativos en los índices espirométricos tras el cambio. Con el tratamiento inicial, el 46,9% presentó ≥ 1 visita a urgencias (total: 50 consultas). Tras el cambio por budesonida/formoterol, el 21% requirió al menos una visita a urgencias (total: 14 consultas; p < 0,01). La proporción de pacientes con ≥ 2 consultas a urgencias fue de 19,7% con el tratamiento basal y de 1,6% tras el cambio a budesonida/formoterol (p < 0,01). No se observaron diferencias significativas en la cantidad de hospitalizaciones. En este estudio del mundo real de pacientes con asma moderada a grave, el cambio del tratamiento a budesonida/formoterol se asoció con reducción significativa de las consultas a urgencias, a pesar de no detectarse cambios de significación estadística en los índices espirométricos habituales.

Asthma is characterized by its deleterious impact, including a high cost to the healthcare system. In patients with poorly controlled asthma despite treatment, a maintenance regimen of inhaled corticosteroids and formoterol is proposed. The aim of this retrospective, observational study was to evaluate the spirometric changes after switching the controller medication in patients with moderate to severe asthma attended in our institution ("Hospital Clínico de Magallanes"), as well as the variation in the number of severe exacerbations (consultation to an emergency department and/or hospitalization for asthma). Sixty-one adults with moderate to severe asthma (median age: 60 years-old [range: 21-87], women: 69.4%; atopic/allergic comorbidity: 79%; other comorbidities: 46.8%) in whom treatment with fluticasone/salmeterol 250/25 μg was switched to budesonide/formoterol 160/4.5 μg participated in our study. No significant changes in spirometric parameters were observed after the replacement treatment. With the initial treatment, 46.9% patients presented ≥ 1 visit to the emergency department (total: 50 visits). After the switch to budesonide/formoterol, 21% required at least one emergency department visit (total: 14 consultations; p < 0.01). The proportion of patients with ≥ 2 emergency department visits was 19.7% with baseline treatment and 1.6% after switching to budesonide/formoterol (p < 0.01). No significant differences were observed in the number of hospitalizations. In this real-world study of moderate to severe asthma patients, switching to budesonide/formoterol was associated with a significant reduction in emergency department visits, despite no statistically significant changes in the usual spirometric parameters.

Symptom Burden and GOLD Classification in Medicare Advantage Patients with COPD Initiating Umeclidinium/Vilanterol or Fluticasone Propionate/Salmeterol Therapy.

Background: Long-acting muscarinic antagonist/long-acting ß2-agonist (LAMA/LABA) provide greater improvements in lung function and symptoms than inhaled corticosteroid (ICS)/LABA in patients with chronic obstructive pulmonary disease (COPD). This study evaluated symptom burden and Global Initiative for Obstructive Lung Disease (GOLD) categorization among patients who recently initiated umeclidinium/vilanterol (UMEC/VI; LAMA/LABA) or fluticasone propionate/salmeterol (FP/SAL; ICS/LABA) single-inhaler dual therapy. Methods: COPD-diagnosed Medicare Advantage enrollees aged ≥65 years were identified from the Optum Research Database (ORD). Eligible patients had ≥1 pharmacy claim for UMEC/VI or FP/SAL in the 6-month period before sample identification, with no evidence of triple therapy (ICS/LAMA/LABA), asthma, or lung cancer. Symptom burden was assessed via cross-sectional surveys using the COPD Assessment Test (CAT) and modified Medical Research Council (mMRC) dyspnea scale. Patients were classified into GOLD categories using patient-reported symptoms and claims-based exacerbation history. Treatment groups were balanced on potential confounders using inverse probability of treatment weighting (IPTW). CAT and mMRC scores were analyzed with generalized linear regression models using IPTW propensity scores. Results: The final analytic sample included 789 respondents (UMEC/VI: N=392; FP/SAL: N=397). Approximately 66% patients were classified as GOLD B when assessing symptoms with CAT and mMRC together, or CAT alone; more patients were classified as GOLD A (~40%) than GOLD B (~36%) using mMRC alone. Proportions of patients in each GOLD group were similar between treatment cohorts. Post-IPTW multivariable modeling showed similar symptom burden between treatment groups. Conclusion: After controlling for baseline characteristics, symptom burden was similar between patients receiving UMEC/VI or FP/SAL. GOLD classification using mMRC produced more conservative results compared with CAT, potentially underestimating patient symptoms. Many patients receiving FP/SAL were classified as GOLD A or B, despite GOLD recommending non-ICS-containing therapy in these patients. These findings support the need for routine assessment of symptoms in patients with COPD.

24-Hour Serial Spirometric Assessment of Once-Daily Fluticasone Furoate/Umeclidinium/Vilanterol Versus Twice-Daily Budesonide/Formoterol in Patients with COPD: Analysis of the FULFIL Study.

INTRODUCTION: Few studies have utilized 24-h serial spirometry to compare the effects of inhaled chronic obstructive pulmonary disease (COPD) therapies on lung function. The FULFIL study previously reported significant lung function improvements with once-daily single-inhaler fluticasone furoate/umeclidinium/vilanterol (FF/UMEC/VI) versus twice-daily single-inhaler budesonide/formoterol (BUD/FOR) in patients with symptomatic COPD at risk of exacerbations. METHODS: This prespecified analysis evaluated 24-h serial spirometry data from a subgroup of 406 patients in FULFIL. BUD/FOR twice-daily dosing was maintained during 24-h spirometry. A post hoc analysis evaluated serial forced expiratory volume in 1 s (FEV1) at day 1 and week 24 by disease severity at screening (FEV1 < 50% predicted and no moderate or severe exacerbation in prior year, FEV1 < 50% predicted and ≥ 1 moderate or severe exacerbation in prior year, and FEV1 ≥ 50% and < 80% predicted and ≥ 2 moderate or ≥ 1 severe exacerbations in prior year). RESULTS: Odds of achieving a ≥ 100-mL increase from baseline in FEV1 within the first 6 h post dose on day 1 were significantly greater with FF/UMEC/VI than BUD/FOR [odds ratio 2.79 (95% confidence interval 1.56-4.98); p < 0.001]. FF/UMEC/VI led to greater improvements in weighted mean FEV1 over 0-6, 0-12, 0-24, and 12-24 h on day 1 and at week 24, with the greatest between-group differences at week 24 (range 196-210 mL; all p < 0.001). Significant between-treatment differences in FEV1 and forced vital capacity (FVC) in favor of FF/UMEC/VI versus BUD/FOR were seen at all time points at week 24 (FEV1 range 156-231 mL, all p < 0.001; FVC range 139-309 mL, all p ≤ 0.002). Serial FEV1 results were consistent irrespective of disease severity at screening. CONCLUSION: These findings further demonstrate sustained lung function benefits with once-daily FF/UMEC/VI single-inhaler triple therapy in patients with symptomatic COPD at risk of exacerbations across a range of disease severities.

Impact of baseline symptoms and health status on COPD exacerbations in the FLAME study.

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

Preventing Clinically Important Deterioration of COPD with Addition of Umeclidinium to Inhaled Corticosteroid/Long-Acting ß2-Agonist Therapy: An Integrated Post Hoc Analysis.

INTRODUCTION: Assessing clinically important measures of disease progression is essential for evaluating therapeutic effects on disease stability in chronic obstructive pulmonary disease (COPD). This analysis assessed whether providing additional bronchodilation with the long-acting muscarinic antagonist umeclidinium (UMEC) to patients treated with inhaled corticosteroid (ICS)/long-acting ß2-agonist (LABA) therapy would improve disease stability compared with ICS/LABA therapy alone. METHODS: This integrated post hoc analysis of four 12-week, randomized, double-blind trials (NCT01772134, NCT01772147, NCT01957163, NCT02119286) compared UMEC 62.5 µg with placebo added to open-label ICS/LABA in symptomatic patients with COPD (modified Medical Research Council dyspnea scale score ≥ 2). A clinically important deterioration (CID) was defined as: a decrease from baseline of ≥ 100 mL in trough forced expiratory volume in 1 s (FEV1), an increase from baseline of ≥ 4 units in St George's Respiratory Questionnaire (SGRQ) total score, or a moderate/severe exacerbation. Risk of a first CID was evaluated in the intent-to-treat (ITT) population and in patients stratified by Global initiative for chronic Obstructive Lung Disease (GOLD) classification, exacerbation history and type of ICS/LABA therapy. Adverse events (AEs) were also assessed. RESULTS: Overall, 1637 patients included in the ITT population received UMEC + ICS/LABA (n = 819) or placebo + ICS/LABA (n = 818). Additional bronchodilation with UMEC reduced the risk of a first CID by 45-58% in the ITT population and all subgroups analyzed compared with placebo (all p < 0.001). Improvements were observed in reducing FEV1 (69% risk reduction; p < 0.001) and exacerbation (47% risk reduction; p = 0.004) events in the ITT population. No significant reduction in risk of a SGRQ CID was observed. AE incidence was similar between treatment groups. CONCLUSION: Symptomatic patients with COPD receiving ICS/LABA experience frequent deteriorations. Additional bronchodilation with UMEC significantly reduced the risk of CID and provided greater short-term stability versus continued ICS/LABA therapy in these patients.

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

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

Post-radiotherapy maintenance treatment with fluticasone propionate and salmeterol for lung cancer patients with grade III radiation pneumonitis: A case report.

RATIONALE: This combination of fluticasone propionate (FP) and the long-acting ß2-agonist salmeterol (Salm) can control the symptoms of asthma and COPD better than FP or Salm on their own and better than the combination of inhaled corticosteroids plus montelukast. FP/Salm has been shown to control symptoms of asthma and COPD better than a double dose of inhaled steroids. The patient in our report had a history of COPD, and suffered relapse of RP when given only steroids. It is possible that COPD history helps explain this patient's more difficult treatment course. Therefore, this combination may be more effective than inhaled steroids for patients with a history of COPD. PATIENT CONCERS: This patient suffered adverse reactions triggered by methylprednisolone: weight gain, hyperglycaemia and sleep disturbance after more than two months of intravenous and oral prednisolone. These reactions disappeared when we switched the patients to FP/Salm maintenance therapy. DIAGNOSES: The patient underwent upper right lobectomy in September 2011. Immunohistochemistry indicated low squamous cell differentiation, and he was diagnosed with stage IIB disease (T2N1M0) according to the Union for International Cancer Control (UICC) (7th edition).One month after repeat radiotherapy, the patient experienced fever (37.6°C), cough, chest distress and shortness of breath. We performed serologic tests, laboratory tests for procalcitonin and C-reactive protein, as well as sputum and blood cultures to rule out bacterial infection. Chest CT showed consolidation with air bronchogram in the hilum of the right lung and ground-glass densities in the right lower lobe and left upper lobe. These radiographic signs are typical of RP. Since the patient required oxygen, he was diagnosed with grade III RP. INTERVENTIONS: After the patinet was diagnosed with grade III RP. The patient was immediately prescribed oxygen, anti-infectives for prophylaxis, treatments to facilitate expectoration and prevent asthma, and most importantly, intravenous methylprednisone at an initial dose of 60  per day. And we cut the steroid dose in half every one week when the patient's symptoms improved obviously, and the patchy shadow on the chest radiograph sharply reduced. Then we give him FP (500 mg)/Salm (50 mg) twice daily for two months. Then the dose was halved for an additional two months. OUTCOMES: The patient showed no signs of tumor or RP relapse by the last follow-up in March 2018. LESSONS: This maintenance therapy of FP/Salm for patient with grade III RP may help avoid relapse when steroid therapy is tapered, particularly for patients with a history of COPD. It may also reduce risk of steroid-associated adverse effects. Based on the results observed with our patient, we intend to design a prospective trial to assess the efficacy of FP/Salm when used as preventive treatment for patients at high risk of RP, and when used as maintenance treatment for patients with grade III RP.

Once-daily fluticasone furoate/vilanterol versus twice-daily fluticasone propionate/salmeterol in patients with asthma well controlled on ICS/LABA.

OBJECTIVE: We aimed to demonstrate non-inferiority of once-daily fluticasone furoate/vilanterol 100/25 µg (FF/VI) to twice-daily fluticasone propionate/salmeterol 250/50 µg (FP/SAL) in adults/adolescents with asthma well controlled on inhaled corticosteroid/long-acting ß2 agonist (ICS/LABA). METHODS: This was a randomized, double-blind, double-dummy, parallel-group, 24-week study (NCT02301975/GSK study 201378). Patients whose asthma met study-defined criteria for control were randomized 1:1:1 to receive FF/VI, FP/SAL or twice-daily FP 250 µg for 24 weeks. Primary endpoint was change from baseline in evening trough forced expiratory volume in 1 second (FEV1). Secondary endpoints included rescue-/symptom-free 24-hour periods. Safety was also assessed. RESULTS: The intent-to-treat (ITT) population included 1504 randomized and treated patients (504 FF/VI; 501 FP/SAL; 499 FP); mean age 43.5 years, 64% female. FF/VI demonstrated non-inferiority (using a margin of -100 mL) to FP/SAL for evening trough FEV1 at Week 24 (ITT: 19 mL [95% confidence interval (CI) -11 to 49]; per protocol population [N = 1336]: 6 mL [95% CI -27 to 40]). Improvement in evening trough FEV1 at Week 24 for both FF/VI (123 mL; p < 0.001) and FP/SAL (104 mL; p < 0.001) was greater than FP. FF/VI increased rescue-/symptom-free 24-hour periods by 1.2%/1.2% compared with FP/SAL. All treatments were well tolerated. On-treatment adverse event (AE) rates were 43% to 45% across arms; there were no drug-related serious AEs. CONCLUSIONS: FF/VI was non-inferior to FP/SAL for evening trough FEV1 at 24 weeks. These data suggest that patients well controlled on FP/SAL could step across to FF/VI without loss of control.

Asthma control in adult patients treated with a combination of inhaled corticosteroids and long­acting ß2­agonists: a prospective observational study.

INTRODUCTION    Asthma is a highly prevalent disease that often requires maintenance therapy. Combined inhaled corticosteroid (ICS) and long­acting ß2­agonist (LABA) inhalers are one of the available maintenance treatment options. OBJECTIVES    This prospective observational study aimed to assess asthma control in patients treated with ICS/LABA inhalers and to identify factors related to optimal asthma control. PATIENTS AND METHODS    The study included 5789 asthmatic patients from Poland, treated with one of the following ICS/LABA inhalers at clinically appropriate doses: beclomethasone/formoterol, fluticasone/ salmeterol, or budesonide/formoterol. The follow­up lasted 6 months (4 visits in total). The outcomes were physician-reported and patient­reported asthma control and occurrence of adverse drug reactions. A retrospective logistic regression analysis was performed to identify a potential association between age, obesity, and smoking and the level of disease control. RESULTS    A total of 4469 patients completed the study. Throughout the study period, the rate of patient­reported control of asthma increased from 24.8% to 67.7%, while physician­reported control increased from 22.6% to 66.4%. The incidence of exacerbations decreased from 23.4% to 1.9%. Less than 0.1% of the patients reported adverse drug reactions. Age, obesity (body mass index ≥30 kg/m2), and smoking were confirmed as factors negatively affecting disease control, with combined ICS/LABA inhalers potentially reducing their effect. CONCLUSION    Our results confirm the efficacy and safety of combined ICS/LABA inhalers in a real­life clinical setting. They also corroborate the finding that obesity, older age, and smoking are risk factors for poor asthma control.

Assessment of the efficacy and safety of fluticasone propionate and salmeterol delivered as a combination dry powder via a capsule-based inhaler versus a multi-dose inhaler in patients with chronic obstructive pulmonary disease.

BACKGROUND: This study tested the clinical non-inferiority of the fluticasone propionate/salmeterol combination 50/250 µg (FSC) Rotacaps®/Rotahaler® system, a single unit dose inhaler, with the multi-dose FSC Diskus® inhaler in adults with chronic obstructive pulmonary disease (COPD). METHODS: This multi-centre, randomised, double-blind, double-dummy, two-way cross-over study compared 12 weeks' treatment of FSC administered twice daily using Rotacaps/Rotahaler or Diskus. The primary endpoint was change from baseline in trough morning forced expiratory volume in 1 s (FEV1) at Day 85, and the pre-defined non-inferiority criteria was: the lower limit of the confidence interval (CI) for the treatment difference (Rotacaps/Rotahaler-Diskus) in least squares (LS) mean change from baseline, being greater than -45 mL. Secondary endpoints included change in breathlessness (as measured by transition dyspnoea index (TDI)) and COPD-specific health status measures. RESULTS: The LS mean increase from baseline in trough FEV1 at Day 85 was 116 mL in the Rotacaps/Rotahaler group and 91 mL in the Diskus group (difference in model-adjusted LS mean change: 25 mL (95% CI 2 mL, 47 mL)), the lower limit of the CI for the treatment difference being greater than the protocol-defined criterion for non-inferiority i.e. -45 mL. Data for breathlessness, COPD-specific health status and safety parameters were similar following FSC treatment via either inhaler. CONCLUSIONS: This study demonstrated the clinical non-inferiority of FSC 50/250 µg when administered using Rotacaps/Rotahaler compared with Diskus in patients with COPD. The risk:benefit profile for the two inhalers was comparable.

Replacement of SFC-DPI with SFC-MDI exhaled through the nose improves eosinophilic chronic rhinosinusitis in patients with bronchial asthma.

OBJECTIVE: Eosinophilic chronic rhinosinusitis (ECRS), a subgroup of chronic rhinosinusitis with nasal polyps, is a refractory disease closely associated with bronchial asthma. We recently reported on the efficacy of ultra-fine particle inhaled corticosteroids (ICS) (hydrofluoroalkane-134a-beclomethasone dipropionate: HFA-BDP) exhalation through the nose (ETN) treatment for mild-to-moderate asthmatics with ECRS. However, the effect of HFA-BDP ETN was found to be transient in some cases with severe ECRS and asthma, requiring treatment with higher-dose ICS and long-acting ß2-agonists (LABA). Here, we present a case of refractory ECRS with severe asthma treated with a combination of high-dose ICS and LABA ETN, and we discuss the mechanisms for its effectiveness. METHODS: A 57-year-old man was treated with the combined regimen of HFA-BDP ETN and salmeterol/fluticasone combination (SFC) dry powder inhaler (DPI) for his refractory ECRS with severe asthma. For better control, we replaced SFC-DPI with SFC metered-dose inhaler (MDI) ETN and evaluated the clinical effect and corticosteroid sensitivity. We also examined the flow and deposition of fine particles released by SFC-MDI ETN. RESULTS: After switching to SFC-MDI ETN, the patient's conditions markedly resolved with the restoration of corticosteroid sensitivity and PP2A activity. The fine particles released by SFC-MDI ETN at least partially flowed out through the external nares and seemed to be deposited on the ethmoid sinus.

Efficacy and safety comparison: Fluticasone furoate and fluticasone propionate, after step down from fluticasone furoate/vilanterol in Japanese patients with well-controlled asthma, a randomized trial.

BACKGROUND: For patients with well-controlled asthma, 'step down' of therapy is recommended. We evaluated Japanese patients switching from inhaled corticosteroid (ICS)/long-acting beta2-agonists (LABA; equivalent to fluticasone propionate [FP]/salmeterol [SAL] 250/50 µg twice daily [BD]) to fluticasone furoate (FF)/vilanterol (VI) 100/25 µg, then stepping down to ICS alone. METHODS: This phase III trial had two treatment periods (P): P1, patients with well-controlled asthma on FP/SAL 250/50 µg BD equivalent stepped across to once daily (OD) FF/VI 100/25 µg (open-label, eight weeks); P2, patients remaining 'well controlled' after P1 stepped down to FF 100 µg OD/FP 100 µg BD/FP 250 µg BD (randomized 1:1:1, double-blind, 12 weeks). Co-primary P2 endpoints: percentage of patients with well-controlled asthma; time to withdrawal due to poorly controlled asthma requiring step-up therapy. Adverse events (AEs) were monitored. RESULTS: At the end of P1 (n = 430), 373 (90.5%; 95% confidence interval 87.29-93.18) patients' asthma remained well controlled with FF/VI; in P2 (n = 371), control was maintained in 89.5% (FF 100 µg)/79.5% (FP 100 µg)/83.8% (FP 250 µg) of patients. In P2, 4.9-7.3% of patients were withdrawn due to worsening asthma (time-to-withdrawal cumulative incidence curves were comparable). AEs were reported by 37% of patients during P1; and by 36% (FF 100 µg)/48% (FP 100 µg)/49% (FP 250 µg) of patients in P2. CONCLUSIONS: For patients with well-controlled asthma on mid dose ICS/LABA (equivalent to FP/SAL 250/50 µg BD), control can be maintained when they are stepped across to FF/VI 100/25 µg OD. FF 100 µg OD is an effective step-down therapy from FF/VI 100/25 µg OD with similar efficacy to FP 100 µg BD and FP 250 µg BD.

Combined inhaled corticosteroid and long-acting ß2-adrenergic agonist therapy for noncystic fibrosis bronchiectasis with airflow limitation: An observational study.

BACKGROUND AND OBJECTIVE: There is presently no clear evidence on the effect of combined treatment for non-cystic fibrosis (non-CF) bronchiectasis with inhaled corticosteroid (ICS) and long-acting ß2-adrenergic agonist (LABA). The objective of this study is to assess the efficacy and safety of salmeterol-fluticasone combined inhaled therapy for non-CF bronchiectasis with airflow limitation. METHODS: An observational study was performed in 120 non-CF bronchiectasis patients diagnosed by high-resolution computed tomography (HRCT) scanning of the chest. Patients received either routine therapy or salmeterol-fluticasone (100/500 µg daily) combined inhaled therapy on the basis of routine therapy. Clinical symptoms, health-related quality of life (HRQL), lung function, short-acting ß2-adrenergic agonist (SABA) use, and safety were monitored throughout the study. RESULTS: OF the 120 subjects, 60 received combined inhaled therapy and 60 received routine therapy. Compared to the control group, the combined inhaled therapy group showed significant improvement in their clinical symptom scores (-2.21 vs. -0.31, P = 0.002) and a reduction in number of weekly SABA usage (-4.2 vs. 0.1, P < 0.01). In addition, patients in the inhaled therapy group achieved a significant improvement in HRQL based on mMRC (-1.51 vs. -0.31, P < 0.005) and SGRQ (-7.83 vs. -2.16, P < 0.01) scoring accompanied with no severe adverse events. There were fewer exacerbation frequencies in the combined inhaled therapy group over the 12 months of treatment compared to the control group (1 [0-2] vs. 2 [1-4], P = 0.017). Furthermore, stratified analysis indicated that combined inhaled therapy partially improve lung function for patients for whom it is severely impaired and those with pseudomonas aeruginosa isolated. CONCLUSION: Our results show that salmeterol-fluticasone combined inhaled therapy should be effective and safe for non-CF bronchiectasis patients especially for those patients with poor lung function or pseudomonas aeruginosa isolated.

Assessment of the efficacy and safety of fluticasone propionate and salmeterol delivered as a combination dry powder via a capsule-based inhaler and a multi-dose inhaler in patients with asthma.

BACKGROUND: In developing countries, there is a need for access to affordable inhaled respiratory medicines. This study tested the clinical non-inferiority of fluticasone propionate/salmeterol combination (FSC) 50/250 µg Rotacaps®/Rotahaler® compared with FSC 50/250 µg Diskus®. METHODS: A multi-centre, randomised, double-blind, double-dummy study evaluated 12 weeks, twice daily treatment of FSC 50/250 µg administered using Rotacaps/Rotahaler or Diskus inhaler in a crossover design in patients with asthma (pre-bronchodilator forced expiratory volume in 1 s (FEV1) 40%-85% of predicted, FEV1 reversibility ≥12%, prior stable dose with inhaled corticosteroid (ICS) or ICS/long acting beta-agonist). The primary efficacy endpoint, change from baseline in trough morning FEV1 at Day 85, was analysed using a model for repeated measures analysis. The pre-defined criterion for non-inferiority was the lower limit of the CI (0.025, one-sided significance level) for the treatment difference (Rotacaps/Rotahaler-Diskus) in least squares (LS) mean change from baseline, being greater than -125 mL. Secondary endpoints included serial FEV1 measurements, morning peak expiratory flow (PEF), rescue medication use, day- and night-time asthma symptoms, Asthma Control Test (ACT) scores, and serial cortisol measured over 12 h (area under the curve (AUC0-12)). RESULTS: Treatment with FSC 50/250 µg via Rotacaps/Rotahaler or Diskus resulted in a similar LS mean increase from baseline in trough FEV1 at Day 85 (231 mL and 203 mL respectively). The difference in the model-adjusted LS mean change was 28 mL (95% CI -24 mL, 80 mL), fulfilling the criterion for non-inferiority. Data for all secondary endpoints were similar for the two treatments, supporting the primary endpoint findings. Both treatments were well tolerated and demonstrated similar safety profiles. CONCLUSION: This study demonstrated the clinical non-inferiority of FSC 50/250 µg when administered using Rotacaps/Rotahaler compared with administration using Diskus in patients with asthma, and suggests there is no difference in the risk:benefit profile between the two FSC inhalers.

Efficacy and safety of aclidinium/formoterol versus salmeterol/fluticasone: a phase 3 COPD study.

The efficacy and safety of twice-daily aclidinium bromide/formoterol fumarate was compared with that of salmeterol/fluticasone propionate in patients with stable, moderate-to-severe chronic obstructive pulmonary disease (COPD).AFFIRM COPD (Aclidinium and Formoterol Findings in Respiratory Medicine COPD) was a 24-week, double-blind, double-dummy, active-controlled study. Patients were randomised (1:1) to aclidinium/formoterol 400/12 µg twice-daily via Genuair/Pressair or salmeterol/fluticasone 50/500 µg twice-daily via Accuhaler. The primary end-point was peak forced expiratory volume in 1 s (FEV1) at week 24. Other end-points included Transition Dyspnoea Index (TDI) focal score at week 24, TDI and St George's Respiratory Questionnaire (SGRQ) responders, COPD Assessment Test and SGRQ scores, assessment of COPD symptoms and exacerbations, use of reliever medication, and device preference. Adverse events were monitored throughout.In total, 933 patients were eligible (mean age 63.4 years, 65.1% male). Aclidinium/formoterol was superior to salmeterol/fluticasone in peak FEV1 and noninferior in TDI. Health status and reduction in exacerbation risk were similar in both groups. While both treatments were well tolerated, pneumonia occurred less frequently with aclidinium/formoterol than salmeterol/fluticasone.In stable COPD, aclidinium/formoterol significantly improved bronchodilation versus salmeterol/fluticasone, with equivalent benefits in symptom control and reduction in exacerbation risk. Both treatments were well tolerated and treatment-related adverse events were less common with aclidinium/formoterol.

Corticosteroid modulation of immunoglobulin expression and B-cell function in COPD.

We investigated changes in gene expression that occur in chronic obstructive pulmonary disease (COPD) after corticosteroid treatment and sought to identify the mechanisms that regulate these changes. Biopsy samples were taken from patients with COPD (Global Initiative for Chronic Obstructive Lung Disease stage I to II) before and after treatment with fluticasone propionate (FP)/salmeterol (SM) (50/500, 4 wk). Gene expression was measured by microarray and was confirmed by real-time reverse transcription-quantitative PCR (RT-qPCR). The effect of FP on IgG expression and B-cell proliferation in the presence of oxidative stress was also studied. FP/SM significantly increased the expression of 180 genes while repressing 343 genes. The top 5 down-regulated genes were associated with immunoglobulin production, whereas the immunomodulatory FK506 binding protein (FK506BP) was up-regulated. Genes including IL6, IL8, and TBET-encoding TBX21 were unaffected. FP reduced IgG protein and mRNA expression and proliferation of human B cells through the dephosphorylation of ERK-1/2 via increased DUSP1 (dual-specificity protein phosphatase 1) expression. Consistent with in vivo data, oxidative stress did not prevent FP-induced suppression of IgG expression in human B cells in vitro Changes in expression were validated by RT-qPCR and by gene set enrichment analysis in distinct COPD cohorts. FP may reduce the adaptive immune response in COPD and may be more effective in patients with an increased B-cell/antibody response indicated by high autoantibody titers.-Lee, J., Machin, M., Russell, K.
