Outcomes of patients with COPD switching from multiple-inhaler to once-daily single-inhaler triple therapy in a real-world primary care setting in England: a retrospective pre-post cohort study.

BACKGROUND: Compared with multiple-inhaler triple therapy (MITT), single-inhaler triple therapy (SITT) with fluticasone furoate/umeclidinium/vilanterol (FF/UMEC/VI) demonstrated improved lung function and meaningful improvements in chronic obstructive pulmonary disease (COPD) Assessment Test score. This real-world study compared the effectiveness of switching patients with COPD in England from MITT to once-daily SITT with FF/UMEC/VI by evaluating rates of COPD exacerbation, healthcare resource use (HCRU) and associated direct medical costs. METHODS: Retrospective cohort pre-post study using linked primary care electronic health record and secondary care administrative datasets. Patients diagnosed with COPD at age ≥35 years, with smoking history, linkage to secondary care data and continuous GP registration for 12 months pre-switch and 6 months post-switch to FF/UMEC/VI were included. Index date was the first initiation of an FF/UMEC/VI prescription immediately following MITT use from 15 November 2017 to 30 September 2019. Baseline was 12 months prior to index, with outcomes assessed 6/12 months pre-switch and post-switch, and stratified by prior COPD exacerbation status. RESULTS: We included 2533 patients (mean [SD] age: 71.1 [9.9] years; 52.1% male). In the 6 months post-switch, there were significant decreases in the proportion of patients experiencing ≥1 moderate-to-severe (36.2%-28.9%), moderate only (24.4%-19.8%) and severe only (15.4%-11.8%) COPD exacerbation (each, p<0.0001) compared with the 6 months pre-switch. As demonstrated by rate ratios, there were significant reductions in exacerbation rates of each severity overall (p<0.01) and among patients with prior exacerbations (p<0.0001). In the same period, there were significant decreases in the rate of each COPD-related HCRU and total COPD-related costs (-24.9%; p<0.0001). CONCLUSION: Patients with COPD switching from MITT to once-daily SITT with FF/UMEC/VI in a primary care setting had significantly fewer moderate and severe exacerbations, and lower COPD-related HCRU and costs, in the 6 months post-switch compared with the 6 months pre-switch.

Characteristics of Users and New Initiators of Single- and Multiple-Inhaler Triple Therapy for Chronic Obstructive Pulmonary Disease in Germany.

Purpose: To assess patient characteristics of users and new initiators of triple therapy for chronic obstructive pulmonary disease (COPD) in Germany. Patients and Methods: Retrospective cohort study of patients with COPD and ≥1 prescription for single-inhaler triple therapy (SITT; fluticasone furoate/umeclidinium/vilanterol [FF/UMEC/VI] or beclomethasone dipropionate/glycopyrronium bromide/formoterol [BDP/GLY/FOR]) or multiple-inhaler triple therapy (MITT), using data from the AOK PLUS German sickness fund (1 January 2015-31 December 2019). The index date was the first date of prescription for FF/UMEC/VI or BDP/GLY/FOR (SITT users), or the first date of overlap of inhaled corticosteroid, long-acting ß2-agonist, and long-acting muscarinic antagonist (MITT users). Two cohorts were defined: the prevalent cohort included all identified triple therapy users; the incident cohort included patients newly initiating triple therapy for the first time (no prior use of MITT or SITT in the last 2 years). Patient characteristics and treatment patterns were assessed on the index date and during the 24-month pre-index period. Results: In total, 18,630 patients were identified as prevalent triple therapy users (MITT: 17,945; FF/UMEC/VI: 700; BDP/GLY/FOR: 908; non-mutually exclusive) and 2932 patients were identified as incident triple therapy initiators (MITT: 2246; FF/UMEC/VI: 311; BDP/GLY/FOR: 395; non-mutually exclusive). For both the prevalent and incident cohorts, more than two-thirds of patients experienced ≥1 moderate/severe exacerbation in the preceding 24 months; in both cohorts more BDP/GLY/FOR users experienced ≥1 moderate/severe exacerbation, compared with FF/UMEC/VI and MITT users. Overall, 97.9% of prevalent triple therapy users and 86.4% of incident triple therapy initiators received maintenance treatment in the 24-month pre-index period. Conclusion: In a real-world setting in Germany, triple therapy was most frequently used after maintenance therapy in patients with recent exacerbations, in line with current treatment recommendations.

Triple therapy (a combination of three different respiratory inhaled medications) is recommended for patients with chronic obstructive pulmonary disease (COPD) who experience repeated short-term symptom flare-ups when taking dual therapy (a combination of two different respiratory medications). Previously, patients had to take triple therapy using two or three separate inhalers. More recently, single-inhaler triple therapies have been developed, meaning patients can take all three different medications at the same time via one single inhaler. This study assessed the characteristics of patients who were already receiving triple therapy, or who started triple therapy (either via multiple inhalers or a single inhaler), in Germany between January 2015 and December 2019. In total, 18,630 patients who were already receiving triple therapy during the study period, and 2932 patients who newly started using triple therapy were included. The study reported that more than two-thirds of included patients had experienced at least one flare-up of COPD symptoms in the 2 years before starting triple therapy. Most patients had also received another therapy for COPD before starting triple therapy. A small proportion of patients started taking triple therapy after receiving no other therapy for COPD in the previous 2 years. The results of the study suggest that triple therapy for COPD in Germany is most often used in accordance with recommendations (patients already receiving therapy and experiencing repeated symptom flare-ups).

Tumor-targeted and stimulus-responsive polymeric prodrug nanoparticles to enhance the anticancer therapeutic efficacy of doxorubicin.

Polymeric prodrug nanoparticles have gained increasing attention in the field of anticancer drug delivery because of their dual functions as a drug carrier and a therapeutic agent. Doxorubicin (DOX) is a highly effective chemotherapeutic agent for various cancers but causes cardiotoxicity. In this work, we developed polymeric prodrug (pHU) nanoparticles that serve as both a drug carrier of DOX and a therapeutic agent. The composition of pHU includes antiangiogenic hydroxybenzyl alcohol (HBA) and ursodeoxycholic acid (UDCA), covalently incorporated through hydrogen peroxide (H2O2)-responsive peroxalate. To enhance cancer cell specificity, pHU nanoparticles were surface decorated with taurodeoxycholic acid (TUDCA) to facilitate p-selectin-mediated cancer targeting. TUDCA-coated and DOX-loaded pHU nanoparticles (t-pHUDs) exhibited controlled release of DOX triggered by H2O2, characteristic of the tumor microenvironment. t-pHUDs also effectively suppressed cancer cell migration and vascular endothelial growth factor (VEGF) expression in response to H2O2. In animal studies, t-pHUDs exhibited highly potent anticancer activity. Notably, t-pHUDs, with their ability to accumulate preferentially in tumors due to the p-selectin targeting, surpassed the therapeutic efficacy of equivalent DOX and pHU nanoparticles alone. What is more, t-pHUDs significantly suppressed VEGF expression in tumors and mitigated hepato- and cardiotoxicity of DOX. Given their cancer targeting ability, enhanced therapeutic efficacy and minimized off-target toxicity, t-pHUDs present an innovative and targeted approach with great translational potential as an anticancer therapeutic agent.

Baseline Characteristics and ICS/LAMA/LABA Response in Asthma: Analyses From the CAPTAIN Study.

BACKGROUND: Findings from CAPTAIN (NCT02924688) suggest that treatment response to fluticasone furoate/umeclidinium/vilanterol (FF/UMEC/VI) differs according to baseline type 2 inflammation markers in patients with moderate to severe asthma. Understanding how other patient physiologic and clinical characteristics affect response to inhaled therapies may guide physicians toward a personalized approach for asthma management. OBJECTIVE: To investigate, using CAPTAIN data, the predictive value of key demographic and baseline physiologic variables in patients with asthma (lung function, bronchodilator reversibility, age, age at asthma onset) on response to addition of the long-acting muscarinic antagonist UMEC to inhaled corticosteroid/long-acting ß2-agonist combination FF/VI, or doubling the FF dose. METHODS: Prespecified and post hoc analyses of CAPTAIN data were performed using categorical and continuous variables of key baseline characteristics to understand their influence on treatment outcomes (lung function [trough FEV1], annualized rate of moderate/severe exacerbations, and asthma control [Asthma Control Questionnaire]) following addition of UMEC to FF/VI or doubling the FF dose in FF/VI or FF/UMEC/VI. RESULTS: Adding UMEC to FF/VI led to greater improvements in trough FEV1 versus doubling the FF dose across all baseline characteristics assessed. Doubling the FF dose was generally associated with numerically greater reductions in the annualized rate of moderate/severe exacerbations compared with adding UMEC, independent of baseline characteristics. Adding UMEC and/or doubling the FF dose generally led to improvements in Asthma Control Questionnaire scores irrespective of baseline characteristics. CONCLUSIONS: Unlike previous findings with type 2 biomarkers, lung function, bronchodilator reversibility, age and age at asthma onset do not appear to predict response to inhaled therapy.

Efficacy of umeclidinium/vilanterol according to the degree of reversibility of airflow limitation at screening: a post hoc analysis of the EMAX trial.

BACKGROUND: In patients with chronic obstructive pulmonary disease (COPD), the relationship between short-term bronchodilator reversibility and longer-term response to bronchodilators is unclear. Here, we investigated whether the efficacy of long-acting bronchodilators is associated with reversibility of airflow limitation in patients with COPD with a low exacerbation risk not receiving inhaled corticosteroids. METHODS: The double-blind, double-dummy EMAX trial randomised patients to umeclidinium/vilanterol 62.5/25 µg once daily, umeclidinium 62.5 µg once daily, or salmeterol 50 µg twice daily. Bronchodilator reversibility to salbutamol was measured once at screening and defined as an increase in forced expiratory volume in 1 s (FEV1) of ≥ 12% and ≥ 200 mL 10-30 min post salbutamol. Post hoc, fractional polynomial (FP) modelling was conducted using the degree of reversibility (mL) at screening as a continuous variable to investigate its relationship to mean change from baseline in trough FEV1 and self-administered computerised-Transition Dyspnoea Index (SAC-TDI) at Week 24, Evaluating Respiratory Symptoms-COPD (E-RS) at Weeks 21-24, and rescue medication use (puffs/day) over Weeks 1-24. Analyses were conducted across the full range of reversibility (-850-896 mL); however, results are presented for the range -100-400 mL because there were few participants with values outside this range. RESULTS: The mean (standard deviation) reversibility was 130 mL (156) and the median was 113 mL; 625/2425 (26%) patients were reversible. There was a trend towards greater improvements in trough FEV1, SAC-TDI, E-RS and rescue medication use with umeclidinium/vilanterol with higher reversibility. Improvements in trough FEV1 and reductions in rescue medication use were greater with umeclidinium/vilanterol compared with either monotherapy across the range of reversibility. Greater improvements in SAC-TDI and E-RS total scores were observed with umeclidinium/vilanterol versus monotherapy in the middle of the reversibility range. CONCLUSIONS: FP analyses suggest that patients with higher levels of reversibility have greater improvements in lung function and symptoms in response to bronchodilators. Improvements in lung function and rescue medication use were greater with umeclidinium/vilanterol versus monotherapy across the full range of reversibility, suggesting that the dual bronchodilator umeclidinium/vilanterol may be an appropriate treatment for patients with symptomatic COPD, regardless of their level of reversibility.

Short- and long-term effects of fluticasone furoate/vilanterol in exercising asthmatic adolescents: A randomized and open label trial.

PURPOSE: Relvar® (fluticasone furoate [FF]/vilanterol [VI]) is a once-daily inhaler with bronchodilator effect lasting 24 h. Our aim was to investigate the short- and long-term effects of FF/VI on exercise-induced asthma (EIA) in adolescents. METHODS: Ninety-three adolescent asthmatics aged 12-18 years were referred for evaluation of EIA. Following a positive exercise challenge test (ECT), 22/44 were allocated to a single administration of salbutamol (400 µg) and 22/44 to FF/VI (92/22 µg) in a double-blind method. Thirty-five subjects were reassessed by repeat ECT 30-60 days of FF/VI. RESULTS: Median FEV1 change post-ECT at baseline was -22.8% predicted (interquartile range [IQR] -26.1 and -18.0) for salbutamol and -21.0 (IQR -30.7 and -16.8) for FF/VI. Following bronchodilator, FEV1 improved similarly in both groups. Repeat ECT following 30-60 days of FF/VI resulted in negative ECT in 33/35 subjects; the median decrease in FEV1 of these 35 subjects was 22.6% predicted (IQR 29-18) before, and 4.6% predicted (IQR 8.7-2.5) after 30-60 days of FF/VI treatment (p < 0.0001). CONCLUSIONS: FF/VI is effective in reversing EIA after 15 min in adolescents and in protecting EIA after 30-60 days in adolescents. Larger studies are needed to assess the effect of FF/VI on EIA.

A single low-energy shockwave pulse opens blood-cerebrospinal fluid barriers and facilitates gastrodin delivery to alleviate epilepsy.

The blood-cerebrospinal fluid barrier (BCSFB) is another gatekeeper between systemic circulation and the central nervous system (CNS), mainly present at the boundary between choroid plexuses and the ventricular system. This study demonstrates BCSFB opening in rats by single pulse of low-energy focused shockwave (FSW, energy flux density 0.03 mJ/mm2, 2 × 106 microbubbles/kg) treatment at lateral ventricle, resulting in significantly elevated cerebrospinal fluid (CSF) concentrations of systemically-administered gastrodin (GTD) (4 times vs. control within 3 hrs) that remained detectable for 24 hrs. The FSW-GTD group had significantly lower Racine's scale (<4) and zero mortality (n = 30) after lithium-pilocarpine-induced epilepsy. Electrophysiological recordings showed decreased epileptiform discharges, and brain section histology revealed reduced inflammation, oxidative stress and apoptosis, when compared with groups without FSW (Racine's scale: 4 ∼ 5; mortality: 26.67 ∼ 36.67%). FSW-mediated BCSFB opening provides a promising alternative for controlled-delivery of therapeutics into the CNS, offering rapid and widespread medication distribution. The technique could by applied in the development of novel therapies for various CNS diseases.

Gastrodin extends the lifespan and protects against neurodegeneration in the Drosophila PINK1 model of Parkinson's disease.

Gastrodin is the main bioactive ingredient of a famous Chinese herb Rhizoma Gastrodiae. Many studies have reported that gastrodin has antioxidative and neuroprotective effects, although its effect on longevity and the mechanism of neuroprotection have not been well studied. Here, we use Drosophila melanogaster as a model to investigate the longevity and neuroprotective effects of gastrodin. Gastrodin significantly extended the lifespan, increased the climbing ability, enhanced the resistance to oxidative stress, increased the enzyme activities of superoxide dismutase (SOD) and catalase (CAT), and promoted the expression of anti-oxidative genes in old flies. The food intake, reproduction and starvation resistance were not affected in flies treated with gastrodin. Moreover, gastrodin delayed the onset of Parkinson-like phenotypes in Pink1B9 mutant flies, including the prolongation of the lifespan, rescue of the climbing ability, rescue of the progressive loss of a cluster of dopaminergic neurons in the protocerebral posterial lateral 1 region, and increase of the dopamine content in the brain. Gastrodin did not ameliorate the tau-induced neurobehavioral deficits in the fly AD model of taupathy. Together, these results indicate that gastrodin could prolong the lifespan by regulating the antioxidant ability, and protect against neurodegeneration in the Pink1B9 model of PD. This suggests that gastrodin can be considered as an ideal therapeutic candidate for drug development towards anti-aging.

Comparison of COPD health care utilization and associated costs across patients treated with LAMA+LABA fixed-dose therapies.

BACKGROUND: There is limited clinical trial and/or real-world evidence comparing differences among currently approved fixed-dose combination (FDC) long-acting muscarinic antagonist (LAMA)/long-acting beta2-agonist (LABA) treatments. OBJECTIVE: To compare chronic obstructive pulmonary disease (COPD)-related and all-cause health care resource utilization (HCRU) and costs between COPD patients initiating tiotropium (TIO) + olodaterol (OLO) versus (a) other LAMA + LABA FDCs and (b) umeclidinium (UMEC) + vilanterol (VI), specifically. METHODS: In this retrospective observational study, patients initiating fixed-dose LAMA + LABA therapy (earliest fill date = index date) between January 1, 2014, and September 30, 2018, were identified using administrative claims data from the Optum Research Database. Patients were followed post-index for 1-12 months. Follow-up was censored at the earliest occurrence of index therapy discontinuation or switch, health plan disenrollment, study end date, or reaching the maximum 12-month allowed duration. Propensity score matching of 1:2 was used to balance differences in baseline characteristics between cohorts for each of the 2 comparisons. Annualized population averages of HCRU and costs were calculated for each cohort as [sum of visits (or costs) for all individuals during the follow-up period] ÷ [sum of follow-up on-treatment time for all individuals] × 365 days. RESULTS: After matching, compared with patients who initiated other LAMA + LABAs or UMEC + VI, patients who initiated TIO + OLO had 14.29% and 16.95% fewer mean annualized per-patient COPD-related emergency department (ED) visits (vs. other LAMA + LABAs: 0.49 vs. 0.59, P = 0.005; vs. UMEC + VI: 0.48 vs. 0.56, P = 0.026) and 3.07% and 3.14% fewer mean annualized per-patient pharmacy fills (vs. other LAMA + LABAs: 12.66 vs. 13.07, P = 0.016; vs. UMEC + VI: 12.62 vs. 13.02, P = 0.022), leading to 17.39% and 21.47% lower mean annualized per-patient COPD-related ED costs (vs. other LAMA + LABAs: $289 vs. $368, P = 0.003; vs. UMEC + VI: $285 vs. $345, P = 0.027) and 4.56% and 5.67% lower mean annualized per-patient pharmacy spending (vs. other LAMA + LABAs: $3,570 vs. $3,741, P < 0.001; vs. UMEC + VI: $3,556 vs. $3,770, P < 0.001) in the follow-up period. Similarly, patients in the TIO + OLO cohort had 15.63% and 21.17% fewer mean annualized per-patient all-cause ED visits (vs. other LAMA + LABAs: 1.08 vs. 1.37, P < 0.001; vs. UMEC + VI: 1.08 vs. 1.28, P = 0.001), 8.29% fewer mean annualized per-patient outpatient visits (vs. UMEC + VI: 13.28 vs. 14.48, P = 0.031), 3.41% fewer mean annualized per-patient pharmacy fills (vs. other LAMA + LABAs: 56.92 vs. 58.93, P = 0.028), 19.48% and 22.28% lower mean annualized per-patient all-cause ED costs (vs. other LAMA + LABAs: $755 vs. $971, P < 0.001; vs. UMEC + VI: $749 vs. $930, P < 0.001), and 10.86% lower mean annualized per-patient outpatient setting costs (vs. UMEC + VI: $3,348 vs. $3,756, P = 0.050). There were no statistically significant differences for the other outcome measures. CONCLUSIONS: In a real-world setting, differences in HCRU and costs were observed between FDC LAMA + LABAs, with patients initiating TIO + OLO having lower ED visits/costs, COPD-related pharmacy fills/costs, and all-cause pharmacy use and outpatient visits/costs than those initiating other FDC LAMA + LABAs or UMEC + VI specifically. The remaining HCRU and cost measures were not significantly different. DISCLOSURES: This study was sponsored by Boehringer Ingelheim Pharmaceuticals, Inc. (BIPI; Ridgefield, CT).

The impact of fluticasone furoate/vilanterol on healthcare resource utilisation in the Salford Lung Study in chronic obstructive pulmonary disease.

AIM: The Salford Lung Study (SLS) in chronic obstructive pulmonary disease (COPD) was a randomised controlled trial evaluating the effectiveness and safety of initiating fluticasone furoate/vilanterol (FF/VI) 100/25 µg versus continuing usual care (UC) in patients with COPD and a history of exacerbations. Here, we investigate the impact of initiating FF/VI on healthcare resource utilisation (HRU) in SLS COPD. METHODS: HRU and interventions were determined from patients' electronic health records. Annual rates of on-treatment all-cause and COPD-related secondary care contacts (SCCs) and primary care contacts (PCCs) for FF/VI versus UC were analysed using a general linear model. Costs were derived from national data sources. RESULTS: Least-squares (LS) mean annual rates of all-cause (9.81 versus 9.36) and COPD-related (1.57 versus 1.48) SCCs were similar for FF/VI and UC, as were rates of all-cause hospitalisations (0.87 versus 0.82). Mean duration of hospital stay/patient was 4.5 and 4.2 days, respectively. COPD-related SCC mean total cost/patient was £484 FF/VI and £475 UC. LS mean annual rates of all-cause PCCs were significantly higher for FF/VI (21.20 versus 18.88 UC; p < 0.001). LS mean annual rates of COPD-related PCCs were similar for FF/VI and UC (2.42 versus 2.46). All-cause PCC mean total cost/patient was £900 FF/VI versus £811 UC, but COPD-related PCC costs were similar (£116 versus £114). Direct COPD-related total medical costs/patient were significantly lower for FF/VI (LS geometric mean £806 versus £963 UC; p < 0.001). DISCUSSION: In patients with COPD and exacerbation history, FF/VI may represent a less costly alternative to current therapies.GlaxoSmithKline plc. study HZC115151; ClinicalTrials.gov NCT01551758.The reviews of this paper are available via the supplemental material section.

Gastrodin - A potential drug used for the treatment of Tourette Syndrome.

Gastrodin (Gas) represents the major active component of Gastrodia elata, a Chinese herb. Clinically, Gas is widely used for its sedative, anticonvulsive and neuroprotective properties. This work aimed to assess Gas for its efficacy in Tourette Syndrome (TS) treatment. Twenty-four rats were randomized to the blank control (n = 6) and experimental (n = 18) groups. The experimental group was administered continuous injection of 3, 3'-iminodipropionitrile (IDPN) intraperitoneally for 7 days, and subdivided into the IDPN + NS, IDPN + Hal, and IDPN + Gas groups (n = 6). The control and IDPN + NS groups received saline intragastrically, while the IDPN + Hal and IDPN + Gas groups were administered Gas and Haloperidol, respectively, for 8 weeks. Then, micro-positron emission tomography (PET) was performed for measuring the density and brain distribution of dopamine D2 receptors (D2Rs), dopamine transporters (DATs), 5-HT2A receptors (5-HT2ARs) and 5-HT transporters (SERTs). According to stereotypical behavior experiments, IDPN significantly induced abnormal stereotypical behaviors in rats in comparison with control animals. In addition, micro-PET revealed that by reducing the amounts of D2Rs and increasing those of DATs, Gas could significantly reduce stereotypical TS-like behaviors in this rat model system. Furthermore, Gas treatment reduced the density of SERTs, which could indirectly decrease DA release. The current study demonstrated that Gas could be effective in treating TS.

Once daily combined inhaled steroid and ultra long-acting bronchodilator prescribing in pediatric asthma: a dual Center retrospective cohort study.

OBJECTIVE: A high proportion of children and adolescents who have "difficult" or therapy-resistant asthma, are found to have poor adherence to maintenance therapies. Such individuals are thus difficult asthmatics (for reasons of poor adherence) rather than being young people with true difficult asthma. In our centers, once daily ICS/ULABA (Relvar™) is considered if there is an increase in reported interval symptoms, asthma attacks requiring hospital attendance or rescue oral prednisolone, or persistently low lung function despite reported regular use of a twice daily ICS/LABA preparation. In the majority of these young people, a clinical history of overt non-adherence or a clinical suspicion of covert non-adherence will be noted. METHODS: The aim of our retrospective cohort study was to assess the clinical effectiveness of Relvar™ in a selected adolescent asthma population. RESULTS: In a pre-selected group of adolescents with likely poor prior adherence to inhaled therapies, a change to Relvar™ (once daily combined ICS/ULABA) led to improvements in asthma control, as assessed by ED attendances and oral steroid burden. CONCLUSIONS: A prospective study to verify these findings and also explore the effects on quality of life, asthma control, and adherence is warranted.

Efficacy and safety of once-daily single-inhaler triple therapy (FF/UMEC/VI) versus FF/VI in patients with inadequately controlled asthma (CAPTAIN): a double-blind, randomised, phase 3A trial.

BACKGROUND: Despite inhaled corticosteroid plus long-acting ß2-agonist (ICS/LABA) therapy, 30-50% of patients with moderate or severe asthma remain inadequately controlled. We investigated the safety and efficacy of single-inhaler fluticasone furoate plus umeclidinium plus vilanterol (FF/UMEC/VI) compared with FF/VI. METHODS: In this double-blind, randomised, parallel-group, phase 3A study (Clinical Study in Asthma Patients Receiving Triple Therapy in a Single Inhaler [CAPTAIN]), participants were recruited from 416 hospitals and primary care centres across 15 countries. Participants were eligible if they were aged 18 years or older, with inadequately controlled asthma (Asthma Control Questionnaire [ACQ]-6 score of ≥1·5) despite ICS/LABA, a documented health-care contact or a documented temporary change in asthma therapy for treatment of acute asthma symptoms in the year before screening, pre-bronchodilator FEV1 between 30% and less than 85% of predicted normal value, and reversibility (defined as an increase in FEV1 of ≥12% and ≥200 mL in the 20-60 min after four inhalations of albuterol or salbutamol) at screening. Participants were randomly assigned (1:1:1:1:1:1), via central based randomisation stratified by pre-study ICS dose at study entry, to once-daily FF/VI (100/25 µg or 200/25 µg) or FF/UMEC/VI (100/31·25/25 µg, 100/62·5/25 µg, 200/31·25/25 µg, or 200/62·5/25 µg) administered via Ellipta dry powder inhaler (Glaxo Operations UK, Hertfordshire, UK). Patients, investigators, and the funder were masked to treatment allocation. Endpoints assessed in the intention-to-treat population were change from baseline in clinic trough FEV1 at week 24 (primary) and annualised moderate and/or severe asthma exacerbation rate (key secondary). Other secondary endpoints were change from baseline in clinic FEV1 at 3 h post-dose, St George's Respiratory Questionnaire (SGRQ) total score, and ACQ-7 total score, all at week 24. Change from baseline in Evaluating Respiratory Symptoms in Asthma total score at weeks 21-24 was also a secondary endpoint but is not reported here. Exploratory analyses of biomarkers of type 2 airway inflammation on treatment response were also done. This study is registered with ClinicalTrials.gov, NCT02924688, and is now complete. FINDINGS: Between Dec 16, 2016, and Aug 31, 2018, 5185 patients were screened and 2439 were recruited and randomly assigned to FF/VI (100/25 µg n=407; 200/25 µg n=406) or FF/UMEC/VI (100/31·25/25 µg n=405; 100/62·5/25 µg n=406; 200/31·25/25 µg n=404; 200/62·5/25 µg n=408), with three patients randomly assigned in error and not included in analyses. In the intention-to-treat population, 922 (38%) patients were men, the mean age was 53·2 years (SD 13·1) and body-mass index was 29·4 (6·6). Baseline demographics were generally similar across all treatment groups. The least squares mean improvement in FEV1 change from baseline for FF/UMEC/VI 100/62·5/25 µg versus FF/VI 100/25 µg was 110 mL (95% CI 66-153; p<0·0001) and for 200/62·5/25 µg versus 200/25 µg was 92 mL (49-135; p<0·0001). Adding UMEC 31·25 µg to FF/VI produced similar improvements (FF/UMEC/VI 100/31·25/25 µg vs FF/VI 100/25 µg: 96 mL [52-139; p<0·0001]; and 200/31·25/25 µg vs 200/25 µg: 82 mL [39-125; p=0·0002]). These results were supported by the analysis of clinic FEV1 at 3 h post-dose. Non-significant reductions in moderate and/or severe exacerbation rates were observed for FF/UMEC 62·5 µg/VI versus FF/VI (pooled analysis), with rates lower in FF 200 µg-containing versus FF 100 µg-containing treatment groups. All pooled treatment groups demonstrated mean improvements (decreases) in SGRQ total score at week 24 compared with baseline in excess of the minimal clinically important difference of 4 points; however, there were no differences between treatment groups. For mean change from baseline to week 24 in asthma control questionnaire-7 score, improvements (decreases) exceeding the minimal clinically important difference of 0·5 points were observed in all pooled treatment groups. Adding UMEC to FF/VI resulted in small, dose-related improvements compared with FF/VI (pooled analysis: FF/UMEC 31·25 µg/VI versus FF/VI, -0·06 (95% CI -0·12 to 0·01; p=0·094) FF/UMEC 62·5 µg/VI versus FF/VI, -0·09 (-0·16 to -0·02, p=0·0084). By contrast with adding UMEC, the effects of higher dose FF on clinic trough FEV1 and annualised moderate and/or severe exacerbation rate were increased in patients with higher baseline blood eosinophil count and exhaled nitric oxide. Occurrence of adverse events was similar across treatment groups (patients with at least one event ranged from 210 [52%] to 258 [63%]), with the most commonly reported adverse events being nasopharyngitis (51 [13%]-63 [15%]), headache (19 [5%]-36 [9%]), and upper respiratory tract infection (13 [3%]-24 [6%]). The incidence of serious adverse events was similar across all groups (range 18 [4%]-25 [6%)). Three deaths occurred, of which one was considered to be related to study drug (pulmonary embolism in a patient in the FF/UMEC/VI 100/31·25/25 µg group). INTERPRETATION: In patients with uncontrolled moderate or severe asthma on ICS/LABA, adding UMEC improved lung function but did not lead to a significant reduction in moderate and/or severe exacerbations. For such patients, single-inhaler FF/UMEC/VI is an effective treatment option with a favourable risk-benefit profile. Higher dose FF primarily reduced the rate of exacerbations, particularly in patients with raised biomarkers of type 2 airway inflammation. Further confirmatory studies into the differentiating effect of type 2 inflammatory biomarkers on treatment outcomes in asthma are required to build on these exploratory findings and further guide clinical practice.

Effect of Age on the Efficacy and Safety of Once-Daily Single-Inhaler Triple-Therapy Fluticasone Furoate/Umeclidinium/Vilanterol in Patients With COPD: A Post Hoc Analysis of the Informing the Pathway of COPD Treatment Trial.

BACKGROUND: In the Informing the Pathway of COPD Treatment (IMPACT) trial, single-inhaler triple-therapy fluticasone furoate (FF), umeclidinium (UMEC), and vilanterol (VI) reduced moderate/severe exacerbation rates vs FF/VI and UMEC/VI in patients with symptomatic COPD and a history of exacerbations, with a similar safety profile. RESEARCH QUESTION: Are trial outcomes with single-inhaler triple-therapy FF/UMEC/VI vs FF/VI and UMEC/VI affected by age in patients with symptomatic COPD and a history of exacerbations? STUDY DESIGN AND METHODS: IMPACT was a phase III, double-blind, 52-week trial. Patients ≥ 40 years of age with symptomatic COPD and ≥ 1 moderate/severe exacerbation in the previous year were randomly assigned 2:2:1 to FF/UMEC/VI 100/62.5/25 µg, FF/VI 100/25 µg, or UMEC/VI 62.5/25 µg. End points assessed by age included annual rate of moderate/severe exacerbations, change from baseline (CFB) in trough FEV1, proportion of St. George's Respiratory Questionnaire (SGRQ) responders (≥ 4 units decrease from baseline in SGRQ total score), and safety. RESULTS: The intention-to-treat population comprised 10,355 patients; 4,724 (46%), 4,225 (41%), and 1,406 (14%) were ≤ 64, 65 to 74, and ≥ 75 years of age, respectively. FF/UMEC/VI reduced on-treatment moderate/severe exacerbation rates vs FF/VI (% reduction [95% CI]: ≤ 64 years, 8% [-1 to 16]; P = .070; 65-74 years, 22% [14-29]; P < .001; ≥ 75 years, 18% [3-31]; P = .021) and vs UMEC/VI (≤ 64 years, 16% [7-25]; P = .002; 65-74 years, 33% [25-41]; P < .001; ≥ 75 years, 24% [6-38]; P = .012), with greatest rate reduction seen in the 65 to 74 and ≥ 75 years subgroups. Post hoc analyses of CFB in trough FEV1 and proportion of SGRQ responders at week 52 were significantly greater with FF/UMEC/VI than with FF/VI or UMEC/VI in all subgroups. No new safety signals were identified. INTERPRETATION: FF/UMEC/VI reduced the rate of moderate/severe exacerbations and improved lung function and health status vs FF/VI and UMEC/VI irrespective of age for most end points, with a similar safety profile.

Real-Life Clinical and Functional Effects of Fluticasone Furoate/Umeclidinium/Vilanterol-Combined Triple Therapy in Patients with Chronic Obstructive Pulmonary Disease.

BACKGROUND: Triple therapy consisting of a drug association including an inhaled corticosteroid, a long-acting muscarinic receptor antagonist and a long-acting ß2-adrenergic agonist, delivered via a single device, can be a valuable treatment for chronic obstructive pulmonary disease (COPD) patients experiencing frequent disease exacerbations. OBJECTIVES: The aim of this real-life, single-center, observational study was to evaluate, in 44 COPD patients with recurrent exacerbations, the effects of the triple inhaled therapy combining fluticasone furoate, umeclidinium, and vilanterol (FF/UMEC/VI). METHODS: Within such a therapeutic context, several clinical and lung functional parameters were considered at baseline and after 24 weeks of treatment with combined inhaled triple therapy. RESULTS: With respect to baseline, after 24 weeks of treatment with FF/UMEC/VI, significant changes were recorded with regard to Modified British Medical Research Council (p < 0.0001) and COPD Assessment Test (p < 0.0001) scores, COPD exacerbations (p < 0.001), forced expiratory volume in the first second (p < 0.001), residual volume (p < 0.01), forced mid-expiratory flow between 25 and 75% of FVC (p < 0.0001), inspiratory capacity (p < 0.01), forced vital capacity (p < 0.05), and peak expiratory flow (p < 0.0001). Moreover, in a subgroup of 28 patients, a significant increase of diffusion lung capacity (p < 0.01) was also detected. CONCLUSIONS: In conclusion, our real-life results suggest that triple inhaled therapy with FF/UMEC/VI, when given to COPD patients with frequent exacerbations, is able to positively impact on dyspnea and global health status as well as to significantly decrease COPD exacerbations and improve airflow limitation and lung hyperinflation.

Single inhaler triple therapy (FF/UMEC/VI) versus FF/VI and UMEC/VI in patients with COPD: subgroup analysis of the China cohort in the IMPACT trial.

OBJECTIVES: Chronic obstructive pulmonary disease (COPD) is becoming a leading cause of morbidity and mortality in China. In the IMPACT trial, fluticasone furoate[FF]/umeclidinium[UMEC]/vilanterol[VI] single-inhaler triple therapy demonstrated lower rates of moderate/severe exacerbations than dual therapy with FF/VI or UMEC/VI in patients with symptomatic COPD and a history of exacerbations. This analysis investigates the China cohort and its consistency with the overall ITT population. METHODS: 10,355 patients were randomized 2:2:1 to once-daily FF/UMEC/VI 100/62.5/25 µg, FF/VI 100/25 µg, or UMEC/VI 62.5/25 µg for 52 weeks. Endpoints included: annual rates of exacerbations, time-to-first on-treatment moderate/severe exacerbation and change from baseline in trough forced expiratory volume in 1 s (FEV1) at Week-52. Clinical trial registration is NCT02164513 (CTT116855). RESULTS: 535 patients (5.2%) were from China. Annual on-treatment moderate/severe exacerbation rate was 0.81 with FF/UMEC/VI versus 0.96 with FF/VI (rate ratio: 0.84; 95% confidence interval [CI]: 0.64, 1.11; p = .227) and 0.80 with UMEC/VI (rate ratio: 1.02; 95% CI: 0.72, 1.44; p = .929). Hazard ratio for time-to-first moderate/severe exacerbation was 0.84 (95% CI: 0.63, 1.11; p = .218) for FF/UMEC/VI versus FF/VI and 0.89 (95% CI: 0.62, 1.27; p = .516) versus UMEC/VI. Significant improvements in mean change from baseline in trough FEV1 were observed for FF/UMEC/VI versus FF/VI (treatment difference 137 mL; 95% CI: 86, 188; p < .001) and UMEC/VI (63 mL; 0, 125; p = .050). Health status was improved with FF/UMEC/VI versus both dual therapies. Results were similar to the overall ITT population. No new safety signals were identified. CONCLUSIONS: Single-inhaler triple therapy with FF/UMEC/VI versus FF/VI or UMEC/VI reduced the rate and risk of exacerbations, and improved lung function and health status in the China cohort similar to the overall ITT population. No new safety signals were identified.

Impact of baseline COPD symptom severity on the benefit from dual versus mono-bronchodilators: an analysis of the EMAX randomised controlled trial.

RATIONALE: Symptom relief is a key treatment goal in patients with chronic obstructive pulmonary disease (COPD). However, there are limited data available on the response to bronchodilator therapy in patients at low risk of exacerbations with different levels of symptom severity. This study compared treatment responses in patients with a range of symptom severities as indicated by baseline COPD assessment test (CAT) scores. METHODS: The 24-week EMAX trial evaluated the benefits of umeclidinium/vilanterol versus umeclidinium or salmeterol in symptomatic patients at low exacerbation risk who were not receiving inhaled corticosteroids. This analysis assessed lung function, symptoms, health status, and short-term deterioration outcomes in subgroups defined by a baseline CAT score [<20 (post hoc) and ⩾20 (pre-specified)]. Outcomes were also assessed using post hoc fractional polynomial modelling with continuous transformations of baseline CAT score covariates. RESULTS: Of the intent-to-treat population (n = 2425), 56% and 44% had baseline CAT scores of <20 and ⩾20, respectively. Umeclidinium/vilanterol demonstrated favourable improvements compared with umeclidinium and salmeterol for the majority of outcomes irrespective of the baseline CAT score, with the greatest improvements generally observed in patients with CAT scores <20. Fractional polynomial analyses revealed consistent improvements in lung function, symptoms and reduction in rescue medication use with umeclidinium/vilanterol versus umeclidinium and salmeterol across a range of CAT scores, with the largest benefits seen in patients with CAT scores of approximately 10-21. CONCLUSIONS: Patients with symptomatic COPD benefit similarly from dual bronchodilator treatment with umeclidinium/vilanterol. Fractional polynomial analyses demonstrated the greatest treatment differences favouring dual therapy in patients with a CAT score <20, although benefits were seen up to scores of 30. This suggests that dual bronchodilation may be considered as initial therapy for patients across a broad range of symptom severities, not only those with severe symptoms (CAT ⩾20).Trial registration: NCT03034915, 2016-002513-22 (EudraCT number).The reviews of this paper are available via the supplemental material section.

Efficacy of FF/UMEC/VI compared with FF/VI and UMEC/VI in patients with COPD: subgroup analysis of the Spain cohort in IMPACT.

OBJECTIVES: The IMPACT trial has compared the benefit in the reduction of moderate/severe exacerbations of single inhaler triple therapy (SITT) with fluticasone furoate (FF)/umeclidinium (UMEC)/vilanterol (VI) versus dual therapy with FF/VI (ICS/LABA) and UMEC/VI (LAMA/LABA) in the treatment of patients with chronic obstructive disease (COPD). This study performs a subgroup analysis of the cohort from Spain in the IMPACT study. MATERIALS AND METHODS: In IMPACT, a 52-week randomized, double-blind, parallel-group, multicenter study (N = 10,355), patients ⩾40 years of age with COPD and ⩾1 moderate/severe exacerbations in the previous year were randomized 2:2:1 to once-daily FF/UMEC/VI 100/62.5/25 µg, FF/VI 100/25 µg or UMEC/VI 62.5/25 µg administered via the Ellipta inhaler. Here, we present a subgroup analysis of the 499 patients from Spain, included in the intent-to-treat (ITT) population in the study. Endpoint assessed included exposure-adjusted rate of moderate and severe exacerbations. RESULTS: In the Spain cohort, the exposure-adjusted rate of on-treatment moderate/severe COPD exacerbations per year for FF/UMEC/VI was 1.31 versus 1.43 and 1.57 for FF/VI and UMEC/VI, respectively. No new adverse events were identified. The results are consistent with those observed in the overall ITT study population. CONCLUSION: In the Spain cohort of the IMPACT study, patients receiving triple therapy with FF/UMEC/VI had a lower exposure-adjusted rate of exacerbations compared with FF/VI and UMEC/VI, similar to the overall population.Study Title: A Phase III, 52 Week, Randomized, Double-blind, 3-arm Parallel Group Study, Comparing the Efficacy, Safety and Tolerability of the Fixed Dose Triple Combination FF/UMEC/VI With the Fixed Dose Dual Combinations of FF/VI and UMEC/VI, All Administered Once-daily in the Morning Via a Dry Powder Inhaler in Subjects With Chronic Obstructive Pulmonary DiseaseURL: https://www.clinicaltrialsregister.eu/ctr-search/search?query=CTT116855/ https://clinicaltrials.gov/ct2/show/NCT02164513Registration number: GSK (CTT116855/NCT02164513).The reviews of this paper are available via the supplemental material section.

Effect of once-daily fluticasone furoate/vilanterol versus vilanterol alone on bone mineral density in patients with COPD: a randomized, controlled trial.

BACKGROUND: The relationship between inhaled corticosteroids and bone mineral density (BMD) remains uncertain despite extensive research. METHODS: This was an international, multicenter, randomized, double-blind, parallel-group, 3-year noninferiority study. Patients with chronic obstructive pulmonary disease (COPD) (⩾40 years of age; smoking history ⩾10 pack years) and at least one native hip evaluable for BMD were enrolled and randomized 1:1, stratified by sex, to treatment with vilanterol (VI) 25 µg or fluticasone furoate/vilanterol (FF/VI) 100 µg/25 µg. BMD measurements were taken via dual-energy X-ray absorptiometry every 6 months. The primary endpoint was assessment of the noninferiority of change from baseline in total hip BMD per year at the -1% noninferiority level. Change from baseline in BMD at the lumbar spine and BMD measurements by sex were secondary endpoints. Incidences of COPD exacerbations and bone fractures throughout the study were also recorded. RESULTS: Of 283 randomized patients, 170 (60%) completed the study. Noninferiority was demonstrated for FF/VI versus VI with regards to change from baseline in total hip BMD per year, with changes of -0.27% and 0.18%, respectively, and a treatment difference of -0.46% per year [95% confidence interval (CI) -0.97 to 0.06]. The treatment difference for FF/VI versus VI regarding lumbar spine BMD was -0.51% per year (95% CI -1.11 to 0.10). COPD exacerbations and bone fracture rates were similar between treatment groups. CONCLUSION: FF/VI showed noninferiority to VI for change from baseline in total hip BMD per year, when assessed at the -1% noninferiority margin in a combined sample of men and women with COPD.The reviews of this paper are available via the supplemental material section.
