BACKGROUND: Previous studies have reported reduced acute exacerbation rates and improved symptom control in asthma patients treated using inhaled corticosteroids plus formoterol maintenance and reliever therapy (MART). Fluticasone furoate (FF) and vilanterol (VIL) also provide rapid bronchodilation and sustained anti-inflammatory effects, however no studies have investigated FF/VIL as MART for asthma control.
METHODS: From October 1, 2021 to September 30, 2023, this retrospective study included asthma patients classified as step 3 or 4 according to the Global Initiative for Asthma guidelines, who were then divided into two groups. One group received BUD/FOR as MART, while the other received FF/VIL as MART. Pulmonary function tests, exacerbation rates, Asthma Control Test (ACT), fractional exhaled nitric oxide (FeNO) levels, and blood eosinophil counts were measured before and after 12 months of treatment.
RESULTS: A total of 161 patients were included, of whom 36 received BUD/FOR twice daily as MART, and 125 received FF/VIL once daily as MART. After 12 months of treatment, the FF/VIL group showed a significant increase in ACT scores by 1.57 (p < 0.001), while the BUD/FOR group had an increase of 0.88 (p = 0.11). In terms of FeNO levels, the BUD/FOR group experienced a decline of -0.2 ppb (p = 0.98), whereas the FF/VIL group had a mild increase of + 0.8 ppb (p = 0.7). Notably, there was a significant difference in the change of FeNO between the two groups (∆ FeNO: -0.2 ppb in BUD/FOR; + 0.8 ppb in FF/VIL, p < 0.001). There were no significant alterations observed in FEV1, blood eosinophil count, or acute exacerbation decline in either group.
CONCLUSIONS: In the current study, patients treated with FF/VIL as MART showed improvements in ACT scores, while those treated with BUD/FOR as MART exhibited a reduction in FeNO levels. However, the difference between the two treatment groups did not reach clinical significance. Thus, FF/VIL as MART showed similar effectiveness to BUD/FOR as MART.

BACKGROUND: The relationship between immediate symptom control, reliever medication use and exacerbation risk on treatment response and factors that modify it have not been assessed in an integrated manner. Here we apply simulation scenarios to evaluate the effect of individual baseline characteristics on treatment response in patients with moderate-severe asthma on regular maintenance dosing monotherapy with fluticasone propionate (FP) or combination therapy with fluticasone propionate/salmeterol (FP/SAL) or budesonide/formoterol (BUD/FOR).
METHODS: Reduction in reliever medication use (puffs/24 h), change in symptom control scores (ACQ-5), and annualised exacerbation rate over 12 months were simulated in a cohort of patients with different baseline characteristics (e.g. time since diagnosis, asthma control questionnaire (ACQ-5) symptom score, smoking status, body mass index (BMI) and sex) using drug-disease models derived from large phase III/IV clinical studies.
RESULTS: Simulation scenarios show that being a smoker, having higher baseline ACQ-5 and BMI, and long asthma history is associated with increased reliever medication use (p < 0.01). This increase correlates with a higher exacerbation risk and higher ACQ-5 scores over the course of treatment, irrespective of the underlying maintenance therapy. Switching non-responders to ICS monotherapy to combination therapy after 3 months resulted in immediate reduction in reliever medication use (i.e. 1.3 vs. 1.0 puffs/24 h for FP/SAL and BUD/FOR, respectively). In addition, switching patients with ACQ-5 > 1.5 at baseline to FP/SAL resulted in 34% less exacerbations than those receiving regular dosing BUD/FOR (p < 0.01).
CONCLUSIONS: We have identified baseline characteristics of patients with moderate to severe asthma that are associated with greater reliever medication use, poor symptom control and higher exacerbation risk. Moreover, the effects of different inhaled corticosteroid (ICS)/long-acting beta agonist (LABA) combinations vary significantly when considering long-term treatment performance. These factors should be considered in clinical practice as a basis for personalised management of patients with moderate-severe asthma symptoms.
In this study we looked at how different factors affect the response to asthma treatment in people with moderate to severe asthma who are taking regular medication. Specifically, we wanted to quantify how much asthma duration, differences in the degree of symptom control and lung function, as well as smoking habit, body weight, and sex influence how well someone responds to regular maintenance therapy. Using computer simulations based on models obtained from data in a large patient population with moderate–severe asthma, we explored scenarios that reflect real-life management of patients undergoing treatment with inhaled corticosteroids alone or in combination with long-acting beta agonists over a 12-month period. We looked at how much reliever inhaler they use, how well they rate their asthma control, and how often they have asthma attacks. By considering these results together, we evaluated how well the treatments work on ongoing symptoms and/or reduce the risk of future asthma attacks. Our simulations showed that smokers, people with higher asthma symptom scores, who are obese, and have a longer history of asthma tend to use their reliever inhalers more often. This was linked to a higher risk of having asthma attacks and worse symptom control. Switching those patients who do not respond well to their initial treatment with corticosteroid to combination therapy reduced how much reliever inhaler they need. Also, the effects of fluticasone propionate/salmeterol combination therapy were greater than budesonide/formoterol. In conclusion, our study found that certain patient characteristics can predict how well someone responds to asthma treatment.

UNASSIGNED: Real-life research is needed to evaluate the effectiveness of budesonide/glycopyrrolate/formoterol (BGF) in routine COPD primary care management. We assessed the frequency of medication success among patients with COPD who initiated BGF using real-world data.
UNASSIGNED: Patients with a recorded diagnostic COPD code who started BGF with ≥2 prescriptions within 90-days were identified in the UK Optimum Patient Care Research Database and followed from first prescription until censoring at the end of follow-up (180-days), death, leaving database or end of data at 24/10/2022. The primary outcome was medication success at 90-days post-BGF initiation, defined as no major cardiac or respiratory event (ie no complicated COPD exacerbation, hospitalization for any respiratory event, myocardial infarction, new/hospitalized heart failure, and death) and no incidence of pneumonia. Medication success was also assessed at 180-days post-BGF initiation. Overall real-life medication success was claimed if the lower 95% confidence interval (CI) for the proportion of patients meeting the primary outcome was ≥70% (defined a priori).
UNASSIGNED: Two hundred eighty-five patients were included. Prior to BGF initiation, these patients often had severe airflow obstruction (mean ppFEV1: 54.5%), were highly symptomatic (mMRC ≥2: 77.9% (n = 205/263); mean CAT score: 21.7 (SD 7.8)), with evidence of short-acting β2-agonist (SABA) over-use (≥3 inhalers/year: 62.1%, n=179/285), repeat OCS prescriptions (≥2 courses/year: 33.0%, n = 95/285) and multiple primary care consultations (≥2 visits/year: 61.1%, n = 174/285). Overall, 39.6% of patients (n = 113/285) switched from previous triple therapies. Real-life medication success was achieved by 96.5% of patients (n = 275/285 [95% CI: 93.6, 98.3]) during 90-days treatment with BGF and by 91.8% (n = 169/184 [95% CI: 86.9, 95.4]) of patients at 180-days. The prescribed daily dose of SABA remained stable over the study period.
UNASSIGNED: The majority of patients initiating BGF experienced real-life medication success reflecting the absence of severe cardiopulmonary events. These benefits were apparent after 90-days of treatment and sustained over 180-days.

BACKGROUND: Even though increased use of reliever medication, including short-acting beta agonists (SABA), provides an indirect measure of symptom worsening, there have been limited efforts to assess how different patterns of reliever use correlate with symptom control and future risk of exacerbations. Here, we evaluate the effect of individual baseline characteristics on reliever use in patients with moderate-severe asthma on regular maintenance therapy with fluticasone propionate (FP) or combination therapy with fluticasone propionate/salmeterol (FP/SAL) or budesonide/formoterol (BUD/FOR).
METHODS: A drug-disease model describing the number of 24-h puffs and overnight occasions was developed with data from five clinical studies (N = 6212). The model was implemented using a nonlinear mixed effects approach and a Poisson function, considering clinical and demographic baseline characteristics. Goodness of fit and model predictive performance were assessed. Heatmaps were created to summarise the effect of concurrent baseline factors on reliever utilisation.
RESULTS: The final model accurately described individual patterns of reliever use, which is significantly increased with time since diagnosis, smoking, higher Asthma Control Questionnaire (ACQ-5) score and higher body mass index (BMI) at baseline. Whilst the number of puffs decreases slowly after an initial drop relative to the start of treatment, exacerbating patients utilise significantly more reliever than those who do not exacerbate. The mean effect of FP/SAL (median dose: 250/50 μg BID) on reliever use was slightly higher than that of BUD/FOR (median dose: 160/4.5 μg BID), i.e. a 75.3% vs 69.3% reduction in reliever use, respectively.
CONCLUSIONS: The availability of individual-level patient data in conjunction with a parametric approach enabled the characterisation of interindividual differences in the patterns of reliever use in patients with moderate-severe asthma. Taken together, individual demographic and clinical characteristics, as well as exacerbation history, can be considered an indicator of the degree of asthma control. High SABA reliever use suggests suboptimal clinical management of patients on maintenance therapy.
In this study, we tried to understand how patients with moderate to severe asthma use their quick-relief inhalers (like albuterol), how it relates to their symptoms and the risk of having asthma attacks. To evaluate whether differences in reliever inhaler use between patients are associated with factors like smoking or their asthma symptoms at the beginning of treatment, we gathered data from five clinical studies (n = 6212 patients). These data allowed us to create a model that predicts how often patients use their reliever inhalers (expressed as number of puffs in 24 h) during maintenance therapy with inhaled corticosteroids alone or in combination with long-acting beta agonists. The final model showed that reliever inhaler use is higher in patients who have been diagnosed with asthma for > 10 years, are smokers, have higher asthma symptom scores, and are obese or extremely obese. Patients who had asthma attacks also used their reliever inhalers more often. In addition, to understand how relief inhalers are used in real-life situations, we also created heatmaps that include a wide range of patient characteristics. By using individual patient data together with this model, we have learned that smoking, asthma control, BMI, long history of asthma and previous asthma attacks significantly influence reliever use. This information can help physicians and healthcare professionals understand know how well someone’s asthma is managed. A patient who uses their reliever inhaler often is likely not to have their asthma well controlled by their regular medications.

UNASSIGNED: There is currently limited evidence for the optimal timing of triple therapy initiation in Japan, which is crucial for optimizing strategies for the effective treatment of chronic obstructive pulmonary disease (COPD). This study assessed the impact of prompt vs delayed initiation of triple therapy following a COPD exacerbation on clinical and economic outcomes in patients in Japan.
UNASSIGNED: Retrospective cohort study of patients in the Medical Data Vision Co., Ltd. database initiating triple therapy as single-inhaler triple therapy (fluticasone furoate/umeclidinium/vilanterol or budesonide/glycopyrronium/formoterol) or multiple-inhaler triple therapy within 180 days of a moderate-to-severe exacerbation (index). For the main analysis, patients were categorized as prompt or delayed initiators, initiating triple therapy within 0-30 days or 31-180 days of index, respectively. Inverse probability of treatment weighting based on propensity scores was used to adjust for measured confounders between prompt and delayed cohorts.
UNASSIGNED: For the main analysis, 610 (60.3%) and 402 (39.7%) patients were prompt and delayed initiators, respectively. The rate of subsequent moderate-to-severe exacerbations following index exacerbation was numerically lower in prompt vs delayed initiators (weighted rate ratio 0.95, 95% confidence interval [CI]: 0.74-1.21; P = 0.6603). Time-to-first subsequent moderate-to-severe exacerbation increased significantly in prompt vs delayed initiators (weighted hazard ratio 0.77, 95% CI: 0.64-0.93; P = 0.0053). In patients indexed on a severe exacerbation, delayed initiation resulted in significantly higher 90-day all-cause readmissions vs prompt initiation (42.1% vs 30.6%; P = 0.0329 [weighted estimates]). Weighted healthcare resource utilization rates were numerically lower in prompt vs delayed initiators, and weighted direct costs (all cause and COPD-related) were significantly lower in prompt initiators.
UNASSIGNED: This real-world study demonstrated that earlier initiation of triple therapy resulted in several benefits in clinical outcomes for COPD and may also reduce the economic burden of COPD management in Japan.

BACKGROUND: A heavy financial burden is imposed on patients suffering from chronic diseases due to medicine out-of-pocket payments.
OBJECTIVE: This study focuses on assessing the affordability of medications used for chronic respiratory diseases (CRDs) such as asthma, chronic obstructive pulmonary disease (COPD), and cystic fibrosis (CF) in Iran, specifically on the category R medicines listed in the 2017 Iran drug list (IDL) that are used for the treatment of these diseases, based on the anatomical therapeutic chemical (ATC) drug code.
METHODS: The affordability of medicines in mono and combination therapy approaches was assessed in CRDs using the World Health Organization/Health Action International (WHO/HAI) methodology. Accordingly, if out-of-pocket payment for 30-days of pharmacotherapy exceeds one day for the lowest-paid unskilled government worker (LPGW), it\'s considered non-affordable.
RESULTS: Based on the monotherapy approach, our finding demonstrates that all generic medicines of category R were affordable. However, branded drugs such as Symbicort®, Pulmicort Respules®, Flusalmex®, Seretide®, Fluticort Plus®, Seroflo®, and Salmeflo® cost between 1.2 and 2.5 days\' wage of LPGW and considered unaffordable despite 70% insurance coverage. Moreover, based on the affordability ratio in the combination therapy approach, all medicines used in asthma, COPD, and CF patients with mild respiratory problems are affordable except omalizumab (inj), which is non-affordable due to its high price and no insurance coverage.
CONCLUSIONS: Results showed that the existing insurance coverage does not protect households from hardship, so more considerations are needed such as different insurance schedules and patient support programs.

The assessment of future risk has become an important feature in the management of patients with asthma. However, the contribution of patient-specific characteristics and treatment choices to the risk of exacerbation is poorly understood. Here we evaluated the effect of interindividual baseline differences on the risk of exacerbation and treatment performance in patients receiving regular maintenance doses of inhaled corticosteroids (ICS) or ICS/long-acting beta-agonists (LABA) combination therapy.
Exacerbations and changes to asthma symptoms 5-item Asthma Control Questionnaire (ACQ-5) were simulated over a 12-month period using a time-to-event and a longitudinal model developed from phase III/IV studies in patients with moderate-severe asthma (N = 16,282). Simulations were implemented to explore treatment performance across different scenarios, including randomised designs and real-world settings. Treatment options included regular dosing with ICS monotherapy [fluticasone propionate (FP)] and combination therapy [fluticasone propionate/salmeterol (FP/SAL) or budesonide/formoterol (BUD/FOR)]. Exacerbation rate was analysed using the log-rank test. The cumulative incidence of events was summarised stratified by treatment.
Being a woman, smoker, having higher baseline ACQ-5 and body mass index (BMI) and lower forced expiratory volume in the first second (FEV1) are associated with increased exacerbation risk (p < 0.01). This risk is bigger in winter because of the seasonal variation effect. Across the different scenarios, the use of FP/SAL resulted in a 10% lower annual incidence of exacerbations relative to FP or regular dosing BUD/FOR, independently of baseline characteristics. Similar differences in the annual incidence of exacerbations were also observed between treatments in obese patients (BMI ≥ 25-35 kg/m2) (p < 0.01) and in patients who do not achieve symptom control on FP monotherapy.
Individual baseline characteristics and treatment choices affect future risk. Achieving comparable levels of symptom control whilst on treatment does not imply comparable risk reduction, as shown by the lower exacerbation rates in FP/SAL vs. BUD/FOR-treated patients. These factors should be considered as a basis for personalised clinical management of patients with moderate-severe asthma.
The goal of this project was to demonstrate that individual baseline characteristics can affect the risk of exacerbation as well as the overall treatment response in patients receiving regular maintenance doses of inhaled corticosteroids, given as monotherapy or in combination with long-acting beta-agonists. Using computer simulations based on a drug–disease model previously developed from a large pool of patients with moderate–severe asthma symptoms (N = 16,282), we describe how demographic and clinical baseline patient characteristics at the time of treatment start correlate with the risk of exacerbation. Our results indicate that poor symptom control, limited lung function, obesity, smoking and sex are associated with significant increase in the incidence of asthma attacks. Such an effect is augmented in winter because of the contribution of seasonal variation. This analysis also allowed us to assess how different treatments modify or reduce the annual incidence of moderate to severe attacks. In addition, simulated scenarios showed that combination therapy with fluticasone propionate/salmeterol results in 10% fewer asthma attacks relative to budesonide/formoterol combination therapy. Such a difference may be associated with corticosteroid-specific properties, which vary between inhaled corticosteroids. Consequently, even though comparable level of immediate relief and symptom control may be achieved whilst on treatment, these effects do not imply the same long-term reduction in the risk of exacerbation. These factors should be considered as a basis for personalised clinical management of patients with moderate–severe asthma.

Pharmacological asthma management focuses on the use of inhaled corticosteroid (ICS)-containing therapies, which reduce airway inflammation and provide bronchoprotection, improving symptom control and reducing exacerbation risk. ICS underuse due to poor adherence is common, leading to poor clinical outcomes including increased risk of mortality. This article reviews efficacy versus systemic activity profiles for various adherence patterns and dosing regimens of fluticasone furoate (FF)-containing and budesonide (BUD)-containing asthma therapies in clinical trials and real-world studies.
We performed a structured literature review (1 January 2000-3 March 2022) and mathematical modelling analysis of FF-containing and BUD-containing regular daily dosing in patients with mild-to-severe asthma, as-needed BUD/formoterol (FOR) in mild asthma, and BUD/FOR maintenance and reliever therapy (MART) dosing in moderate-to-severe asthma, to assess efficacy (bronchoprotection) and systemic activity (cortisol suppression) profiles of dosing patterns of ICS use in multiple adherence scenarios.
A total of 22 manuscripts were included in full-text review and 18 in the model simulations. Focusing on FF-containing or BUD-containing treatments at comparable adherence rates, regular daily FF or FF/vilanterol (VI) dosing provided more prolonged bronchoprotection and fewer systemic effects than daily BUD, daily BUD/FOR, or BUD/FOR MART dosing, especially in low adherence scenarios. In model simulations and the real-world setting, FF/VI generally provided longer bronchoprotection, lower systemic activity, and greater clinical benefits over BUD/FOR as well as consistently higher adherence.
In this literature review and modelling analysis, FF/VI was found to show clinical advantages on asthma control over BUD/FOR. These findings have implications for helping clinicians select the most suitable inhaled therapy for their patients with asthma.

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.
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.
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.
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.

To evaluate the cost-effectiveness of Budesonide/Glycopyrronium/Formoterol (BUD/GLY/FOR) versus LAMA/LABA and ICS/LABA, respectively, in patients with moderate to severe COPD, from the Spanish National Healthcare System (NHS) perspective.
A lifetime Markov model with monthly cycle length was developed with baseline and treatment effect data from ETHOS clinical trial, together with utility values from literature and Spanish healthcare resource costs (€, 2021). A 3% annual discount rate was used for costs and benefits. The model comprised ten health states: nine forced expiratory volume in 1 second (FEV1)-related, which were divided by three levels of severity: moderate (FEV1 ≥50% and <80%); severe (FEV1 ≥30% and <50%) and very severe (FEV1 <30%) and a death state. Each FEV1-health state was divided into no exacerbation, moderate exacerbation, and severe exacerbations. An expert panel validated data and assumptions. Outcomes were measured as incremental cost per exacerbation avoided, per life year (LY) gained, and per quality-adjusted life-year (QALY) gained (ICUR). One-way (OWSA), scenario, and probabilistic sensitivity analyses (PSA) were performed.
According to this cost-effectiveness analysis based on a Markov model, BUD/GLY/FOR was associated with a lower totals exacerbation per patient (12.80) compared to LAMA/LABA (13.36) and ICS/LABA (13.23) and higher LYs (10.32 vs 10.14 and 10.06, respectively) and QALYs (7.55 vs 7.41 and 7.32, respectively). The incremental costs were €850.95, and €2422.26, respectively, per exacerbation avoided, €2733.38 and €4111.15, respectively, per LY gained and €3461.19 and €4545.24 per QALY gained. OWSA showed that the model was most sensitive to the costs of treatments following discontinuation, but the ICUR remained below the cost-effectiveness threshold of €25,000 per QALY gained. In the PSA, the probability of BUD/GLY/FOR being cost-effective was 91.32% vs LAMA/LABA and 99.29% vs ICS/LABA.
BUD/GLY/FOR is a cost-effective treatment strategy for Spanish NHS patients with COPD compared to dual therapies.
