RESUMO

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).

RESUMO

BACKGROUND: This analysis of the IMPACT study assessed the cardiovascular (CV) safety of single-inhaler triple therapy with fluticasone furoate/umeclidinium/vilanterol (FF/UMEC/VI) versus FF/VI and UMEC/VI dual therapy. METHODS: IMPACT was a 52-week, randomized, double-blind, multicenter Phase III study comparing the efficacy and safety of FF/UMEC/VI 100/62.5/25 mcg with FF/VI 100/25 mcg or UMEC/VI 62.5/25 mcg in patients ≥40 years of age with symptomatic chronic obstructive pulmonary disease (COPD) and ≥1 moderate/severe exacerbation in the previous year. The inclusion criteria for the study were intentionally designed to permit the enrollment of patients with significant concurrent CV disease/risk. CV safety assessments included proportion of patients with and exposure-adjusted rates of on-treatment CV adverse events of special interest (CVAESI) and major adverse cardiac events (MACE), as well as time-to-first (TTF) CVAESI, and TTF CVAESI resulting in hospitalization/prolonged hospitalization or death. RESULTS: Baseline CV risk factors were similar across treatment groups. Overall, 68% of patients (n = 7012) had ≥1 CV risk factor and 40% (n = 4127) had ≥2. At baseline, 29% of patients reported a current/past cardiac disorder and 58% reported a current/past vascular disorder. The proportion of patients with on-treatment CVAESI was 11% for both FF/UMEC/VI and UMEC/VI, and 10% for FF/VI. There was no statistical difference for FF/UMEC/VI versus FF/VI or UMEC/VI in TTF CVAESI (hazard ratio [HR]: 0.98, 95% confidence interval [CI]: 0.85, 1.11; p = 0.711 and HR: 0.92, 95% CI: 0.78, 1.08; p = 0.317, respectively) nor TTF CVAESI leading to hospitalization/prolonged hospitalization or death (HR: 1.19, 95% CI: 0.93, 1.51; p = 0.167 and HR: 0.96, 95% CI: 0.72, 1.27; p = 0.760, respectively). On-treatment MACE occurred in ≤3% of patients across treatment groups, with similar prevalence and rates between treatments. CONCLUSIONS: In a symptomatic COPD population with a history of exacerbations and a high rate of CV disease/risk, the proportion of patients with CVAESI and MACE was 10-11% and 1-3%, respectively, across treatment arms, and the risk of CVAESI was low and similar across treatment arms. There was no statistically significant increased CV risk associated with the use of FF/UMEC/VI versus FF/VI or UMEC/VI, and UMEC/VI versus FF/VI.

RESUMO

Background and objective: Retrospective claims data in patients with chronic obstructive pulmonary disease (COPD) initiating maintenance therapy with inhaled fixed-dose combinations of long-acting muscarinic antagonist/long-acting ß2-agonist (LAMA/LABA) versus inhaled corticosteroid (ICS)/LABA have not been reported. Methods: Retrospective observational study in a COPD-diagnosed population of commercial and Medicare Advantage with Part D (MAPD) enrollees aged ≥40 years from a US health insurer database. Patients initiated umeclidinium/vilanterol (UMEC/VI [62.5/25 µg]) or fluticasone propionate/salmeterol (FP/SAL [250/50 µg]) between April 1, 2014 and August 31, 2016 (index date) and had 12 months continuous enrollment pre- and post-index. Exclusion criteria included an asthma diagnosis in the pre-index period/index date; ICS-, LABA-, or LAMA-containing therapy during the pre-index period; or pharmacy fills for both UMEC/VI and FP/SAL, multiple-inhaler triple therapy, a non-index therapy, or COPD exacerbation on the index date. Adherence (proportion of days covered [PDC] ≥80%) was modeled using weighted logistic regression following inverse probability of treatment weighting (IPTW). Weighted Kaplan-Meier and Cox proportional hazards regression following IPTW were performed for incidence of COPD exacerbation and escalation to multiple-inhaler triple therapy. Results: The study population included 5306 patients (1386 initiating UMEC/VI and 3920 initiating FP/SAL). Adjusted odds of adherence were 2.00 times greater among UMEC/VI than FP/SAL initiators (95% confidence interval [CI]: 1.62─2.46; P<0.001). The adjusted hazard ratio (HR) for first exacerbation was 0.87 (95% CI: 0.74-1.01; P=0.067) among UMEC/VI versus FP/SAL initiators. UMEC/VI initiators had 35% lower adjusted risk of escalation to multiple-inhaler triple therapy (HR 0.65; 95% CI: 0.47-0.89; P=0.008) versus FP/SAL. On-treatment, UMEC/VI initiators had an adjusted 30% reduced risk of a first moderate/severe COPD exacerbation (HR 0.70; 95% CI: 0.54-0.90; P=0.006). Conclusion: Patients with COPD initiating UMEC/VI had higher adherence and longer time before escalation to multiple-inhaler triple therapy than FP/SAL initiators.

RESUMO

INTRODUCTION: The cost-effectiveness of long-acting muscarinic antagonist (LAMA) umeclidinium bromide (UMEC) 62.5 µg as add-on therapy to other maintenance COPD treatments is unknown. METHODS: This analysis assessed the cost-effectiveness of the following in COPD: UMEC + fluticasone furoate/vilanterol 100/25 µg (FF/VI); UMEC + fluticasone propionate/salmeterol 250/50 µg (FP/SAL); and UMEC + several alternative choices of inhaled corticosteroid/long-acting ß2-agonist (ICS/LABA). The model was informed with direct and indirect data from previously published studies, with a UK perspective and a lifetime horizon. Sensitivity analyses were also performed. RESULTS: For the lifetime horizon, compared with FF/VI, FP/SAL and ICS/LABAs, addition of UMEC was associated with incremental costs per quality-adjusted life-years (QALY) of £4050, £7210 and £5780, respectively, and incremental costs per life year gain of £3380, £6020 and £4940. All UMEC-containing regimens resulted in numerically lower exacerbation rates versus comparator regimens over a lifetime horizon. CONCLUSIONS: Addition of UMEC to various ICS/LABA treatments was associated with higher cost than ICS/LABA alone, but was cost-effective in most scenarios.

RESUMO

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.

RESUMO

BACKGROUND: Improved outcomes have been reported for patients with chronic obstructive pulmonary disease (COPD) receiving combination long-acting muscarinic antagonist/long-acting ß2-agonist (LAMA/LABA) therapy compared with LAMA monotherapy. However, little is known about the relative characteristics of these patients and their rates of escalation to triple therapy (TT, combining a LAMA, LABA, and inhaled corticosteroid). This study aimed to characterize patients initiating treatment with the LAMA tiotropium (TIO) and the fixed-dose LAMA/LABA combination therapy umeclidinium/vilanterol (UMEC/VI), and to compare rates of escalation to TT between patients receiving these therapies. METHODS: Retrospective study of patients with COPD enrolled in a US health insurance plan during 2013-2015 and newly initiated on TIO or UMEC/VI. Patients were ≥40 years of age at index (date of therapy initiation) with continuous enrollment for 12 months pre-index and ≥30 days post-index. LAMA users were propensity score matched 1:1 to LAMA/LABA users, with TT initiation rates reported by cohort using pharmacy claims. RESULTS: 35,357 patients initiating on TIO and 2407 patients initiating on UMEC/VI were identified. After propensity score matching, the rate of TT initiation was significantly higher in new TIO users (n = 1320) than in new UMEC/VI users (n = 1320) (0.92 vs 0.49 per 100 months of exposure, respectively; p < 0.001). Relative to the UMEC/VI cohort, the TIO cohort had an 87% higher risk of TT initiation (hazard ratio: 1.87; 95% confidence interval: 1.4-2.5; p = 0.001). CONCLUSIONS: Patients receiving UMEC/VI progressed to TT more slowly, and were at lower risk of progressing to TT, than patients receiving TIO.

RESUMO

BACKGROUND: The benefits of triple therapy for chronic obstructive pulmonary disease (COPD) with an inhaled glucocorticoid, a long-acting muscarinic antagonist (LAMA), and a long-acting ß2-agonist (LABA), as compared with dual therapy (either inhaled glucocorticoid-LABA or LAMA-LABA), are uncertain. METHODS: In this randomized trial involving 10,355 patients with COPD, we compared 52 weeks of a once-daily combination of fluticasone furoate (an inhaled glucocorticoid) at a dose of 100 µg, umeclidinium (a LAMA) at a dose of 62.5 µg, and vilanterol (a LABA) at a dose of 25 µg (triple therapy) with fluticasone furoate-vilanterol (at doses of 100 µg and 25 µg, respectively) and umeclidinium-vilanterol (at doses of 62.5 µg and 25 µg, respectively). Each regimen was administered in a single Ellipta inhaler. The primary outcome was the annual rate of moderate or severe COPD exacerbations during treatment. RESULTS: The rate of moderate or severe exacerbations in the triple-therapy group was 0.91 per year, as compared with 1.07 per year in the fluticasone furoate-vilanterol group (rate ratio with triple therapy, 0.85; 95% confidence interval [CI], 0.80 to 0.90; 15% difference; P<0.001) and 1.21 per year in the umeclidinium-vilanterol group (rate ratio with triple therapy, 0.75; 95% CI, 0.70 to 0.81; 25% difference; P<0.001). The annual rate of severe exacerbations resulting in hospitalization in the triple-therapy group was 0.13, as compared with 0.19 in the umeclidinium-vilanterol group (rate ratio, 0.66; 95% CI, 0.56 to 0.78; 34% difference; P<0.001). There was a higher incidence of pneumonia in the inhaled-glucocorticoid groups than in the umeclidinium-vilanterol group, and the risk of clinician-diagnosed pneumonia was significantly higher with triple therapy than with umeclidinium-vilanterol, as assessed in a time-to-first-event analysis (hazard ratio, 1.53; 95% CI, 1.22 to 1.92; P<0.001). CONCLUSIONS: Triple therapy with fluticasone furoate, umeclidinium, and vilanterol resulted in a lower rate of moderate or severe COPD exacerbations than fluticasone furoate-vilanterol or umeclidinium-vilanterol in this population. Triple therapy also resulted in a lower rate of hospitalization due to COPD than umeclidinium-vilanterol. (Funded by GlaxoSmithKline; IMPACT ClinicalTrials.gov number, NCT02164513 .).

RESUMO

Maintenance pharmacological treatment for stable chronic obstructive pulmonary disease (COPD) is based on inhaled drugs, including long-acting muscarinic receptor antagonists (LAMA), long-acting ß2-adrenoceptor agonists (LABA) and inhaled corticosteroids (ICS). Inhaled pharmacological treatment can improve patients' daily symptoms and reduce decline of pulmonary function and acute exacerbation rate. Treatment with all three inhaled drug classes is reserved for selected, more severe, patients with COPD when symptoms are not sufficiently controlled by dual LABA/LAMA therapy and exacerbations are frequent. This review focuses on the role of single-inhaler triple therapy with once-daily fluticasone furoate/umeclidinium/vilanterol fixed-dose combination, which is in phase III clinical development for maintenance treatment of severe-to-very severe COPD. In this review, we summarize evidence providing the rationale for its use in COPD and discuss the gaps to be filled in this pharmacotherapeutic area.

RESUMO

INTRODUCTION: We report the results of the first direct comparison of the once-daily fixed-dose long-acting muscarinic antagonist/long-acting ß2-agonist (LAMA/LABA) combinations umeclidinium/vilanterol (UMEC/VI) and tiotropium/olodaterol (TIO/OLO) in patients with COPD. METHODS: This was a randomized, two-period crossover open-label study in symptomatic patients with COPD [age 40 years or older, postbronchodilator forced expiratory volume in 1 s (FEV1) of 70% or less and 50% or more of predicted normal values, and modified Medical Research Council Dyspnoea Scale score of 2 or greater] not receiving inhaled corticosteroid therapy. Patients were randomized to receive UMEC/VI (62.5/25 µg once daily) via a multidose dry powder inhaler (ELLIPTA) followed by TIO/OLO (5/5 µg once daily) via a soft mist inhaler (Respimat), each for 8 weeks with an interim 3-week washout or vice versa. The primary end point was the change from baseline in trough FEV1 at week 8 with a noninferiority margin of - 50 mL in the per-protocol (PP) population. The incidence of adverse events was also assessed. RESULTS: In total, 236 patients (mean age 64.4 years, 60% male) were included in the intent-to-treat population and 227 were included in the PP population. UMEC/VI treatment was noninferior in the PP population and superior in the intent-to-treat population to TIO/OLO treatment with regard to trough FEV1 at week 8 [FEV1 change from baseline 180 mL vs 128 mL; difference 52 mL (95% confidence interval 28-77 mL); p < 0.001]. Patients receiving UMEC/VI had twofold increased odds of experiencing a clinically meaningful increase (100 mL or more) from baseline in trough FEV1 at week 8 compared with patients receiving TIO/OLO (odds ratio 2.05; 95% confidence interval 1.34-3.14). Adverse events occurred in 25% of patients in the UMEC/VI group and in 31% of patients in the TIO/OLO group. CONCLUSION: In this first direct comparison of two once-daily fixed-dose LAMA/LABA combinations, superiority was observed for the primary end point of trough FEV1 at week 8 with UMEC/VI compared with TIO/OLO in patients with symptomatic COPD. Both treatments had similar safety profiles. These findings confirm the results of previous indirect LAMA/LABA comparisons, and show that an efficacy gradient exists within the LAMA/LABA class.

RESUMO

Accounting for high mortality and morbidity rates, intracerebral hemorrhage (ICH) remains one of the most detrimental stroke subtypes lacking a specific therapy. Neuroinflammation contributes to ICH-induced brain injury and is associated with unfavorable outcomes. This study aimed to evaluate whether α7 nicotinic acetylcholine receptor (α7nAChR) stimulation ameliorates neuroinflammation after ICH. Male CD-1 mice and Sprague-Dawley were subjected to intracerebral injection of autologous blood or bacterial collagenase. ICH animals received either α7nAChR agonist PHA-543613 alone or combined with α7nAChR antagonist methyllycaconitine (MLA) or Janus kinase 2 (JAK2) antagonist AG490. Neurobehavioral deficits were evaluated at 24 hours, 72 hours, and 10 weeks after ICH induction. Perihematomal expressions of JAK2, signal transducer and activator of transcription 3 (STAT3), tumor necrosis factor-α (TNF-α), and myeloperoxidase (MPO) were quantified via Western blot. Histologic volumetric analysis of brain tissues was conducted after 10 weeks following ICH induction. PHA-543613 improved short-term neurobehavioral (sensorimotor) deficits and increased activated perihematomal JAK2 and STAT3 expressions while decreasing TNF-α and MPO expressions after ICH. MLA reversed these treatment effects. PHA-543613 also improved long-term neurobehavioral (sensorimotor, learning, and memory) deficits and ameliorated brain atrophy after ICH. These treatment effects were reduced by AG490. α7nAChR stimulation reduced neuroinflammation via activation of the JAK2-STAT3 pathway, thereby ameliorating the short- and long-term sequelae after ICH.

RESUMO

INTRODUCTION: Patients with COPD who remain symptomatic on long-acting bronchodilator monotherapy may benefit from step-up therapy to a long-acting bronchodilator combination. This study evaluated the efficacy and safety of umeclidinium (UMEC)/vilanterol (VI) in patients with moderate COPD who remained symptomatic on tiotropium (TIO). METHODS: In this randomized, blinded, double-dummy, parallel-group study (NCT01899742), patients (N=494) who were prescribed TIO for ≥3 months at screening (forced expiratory volume in 1 s [FEV1]: 50%-70% of predicted; modified Medical Research Council [mMRC] score ≥1) and completed a 4-week run-in with TIO were randomized to UMEC/VI 62.5/25 µg or TIO 18 µg for 12 weeks. Efficacy assessments included trough FEV1 at Day 85 (primary end point), 0-3 h serial FEV1, rescue medication use, Transition Dyspnea Index (TDI), St George's Respiratory Questionnaire (SGRQ), and COPD Assessment Test (CAT). Safety evaluations included adverse events (AEs). RESULTS: Compared with TIO, UMEC/VI produced greater improvements in trough FEV1 (least squares [LS] mean difference: 88 mL at Day 85 [95% confidence interval {CI}: 45-131]; P<0.001) and FEV1 after 5 min on Day 1 (50 mL [95% CI: 27-72]; P<0.001). Reductions in rescue medication use over 12 weeks were greater with UMEC/VI versus TIO (LS mean change: -0.1 puffs/d [95% CI: -0.2-0.0]; P≤0.05). More patients achieved clinically meaningful improvements in TDI score (≥1 unit) with UMEC/VI (63%) versus TIO (49%; odds ratio at Day 84=1.78 [95% CI: 1.21-2.64]; P≤0.01). Improvements in SGRQ and CAT scores were similar between treatments. The incidence of AEs was similar with UMEC/VI (30%) and TIO (31%). CONCLUSION: UMEC/VI step-up therapy provides clinical benefit over TIO monotherapy in patients with moderate COPD who are symptomatic on TIO alone.

RESUMO

INTRODUCTION: Inhaled corticosteroids (ICS) alone or in combination with an inhaled long-acting beta2-agonist (LABA) are the preferred long-term treatment for adults and adolescents with symptomatic asthma. Additional drugs include leukotriene-receptor antagonists, slow-release theophylline and the long-acting muscarinic antagonist (LAMA) tiotropium (approved in 2015). There is a need for more effective therapies, as many patients continue to have poorly controlled asthma. Areas covered: New and developing long-acting non-adrenoreceptor synthetic drugs for the treatment of symptomatic chronic asthma despite treatment with an ICS alone or combined with a LABA. Data was reviewed from studies published up until November 2016. Expert opinion: Tiotropium improves lung function and has a modest effect in reducing exacerbations when added to ICS alone or ICS and LABA. The LAMAs umeclidinium and glycopyrronium are under development in fixed dose combination with ICS and LABA. Novel small molecule drugs, such as CRTH2 receptor antagonists, PDE4 inhibitors, protein kinase inhibitors and nonsteroidal glucocorticoid receptor agonists and 'off-label' use of licensed drugs, such as macrolides and statins are under investigation for asthma, although their effectiveness in clinical practice is not established. To better achieve the goal of developing effective novel small molecule drugs for asthma will require greater understanding of mechanisms of disease and the different phenotypes and endotypes of asthma.

RESUMO

BACKGROUND: Chemotherapy-induced nausea and vomiting adversely affects the quality of life of patients who receive chemotherapy via intravenous infusion or transcatheter arterial chemoembolization (TACE). This study aimed to investigate the clinical effects of transcutaneous electrical acupoint stimulation (TEAS) on nausea and vomiting after TACE. METHODS: A total of 142 patients who received TACE with cisplatin for primary or metastatic liver cancer were assigned to the active-acupuncture (n = 72) or placebo-acupuncture (n = 70) groups using a covariate-adaptive randomization at a ratio of 1:1. The acupoints Hegu (LI4), Neiguan (P6), and Zusanli (ST36) were stimulated twice daily for 6 days. The effects of TEAS on nausea and vomiting were assessed by using occurrence rate and severity of these symptoms. Anorexia scale and M. D. Anderson Symptom Inventory (MDASI) scores were secondary endpoints and were used to assess the effect of TEAS on patient appetite and quality of life. The safety of the treatments was also monitored. RESULTS: Between the two groups, the differences in occurrence rates and severities of nausea and vomiting after TACE were not significant (all P > 0.05). From the second day after TACE, anorexia scores were significantly lower in the active-acupuncture group than in the placebo-acupuncture group and continued to decrease over time with treatment (all P values less than 0.01). On days 0, 1, and 2, the mean MDASI scores for the active-acupuncture group were slightly lower than those for the placebo-acupuncture group, but the differences were not statistically significant (all P > 0.05). No significant differences were found between the two groups in the occurrence rate of any adverse event (P > 0.05). CONCLUSION: TEAS appears to be a safe and effective therapy to relieve patients' gastrointestinal discomfort after chemotherapy. Trial registration NCT01895010. Registered 21 June 2013.

RESUMO

Patients with symptomatic advanced chronic obstructive pulmonary disease (COPD) who experience recurrent exacerbations are particularly at risk of poor outcomes and present a significant burden on healthcare systems. The relative merits of treating with different inhaled combination therapies e.g. inhaled corticosteroids (ICS)/long-acting ß2-agonist (LABA), LABA/long-acting muscarinic antagonists (LAMA), ICS/LABA/LAMA, in this patient group are poorly understood, as is reflected in current guidelines. The InforMing the PAthway of COPD Treatment (IMPACT) study will evaluate the efficacy and safety of fluticasone furoate (FF)/umeclidinium (UMEC)/vilanterol (VI) versus FF/VI or UMEC/VI over a 52-week treatment period. The study has been designed with a focus on understanding the comparative merits of each treatment modality in different phenotypes/endotypes.This is a phase III, randomised, double-blind, three-arm, parallel-group, global multicentre study comparing the rate of moderate and severe exacerbations between FF/UMEC/VI and FF/VI or UMEC/VI over a 52-week treatment period. The study aims to recruit 10 000 patients from approximately 1070 centres. Eligible patients are aged ≥40 years, with symptomatic advanced COPD (Global initiative for chronic Obstructive Lung Disease (GOLD) group D) and an exacerbation in the previous 12 months.The first patients were recruited to the IMPACT study (ClinicalTrials.gov: NCT02164513) in June 2014 and the anticipated completion date is July 2017.

RESUMO

Several new fixed-dose combination bronchodilators have been launched in the world, and 3 different types are now available in Japan. Assessing their efficacy relative to each other has not been performed yet. In the present manuscript, characteristics of glycopyrronium/indacaterol, umeclidinium/vilanterol and tiotropium/olodaterol were reviewed. In particular, changes in trough and peak forced expiratory volume in 1 second (FEV1), St George's Respiratory Questionnaire (SGRQ) total scores, and transitional dyspnea index (TDI) focal scores were reviewed in these bronchodilators.

RESUMO

Benefits of triple therapy with a long-acting muscarinic antagonist (LAMA), added to inhaled corticosteroid (ICS)/long-acting ß2-agonist (LABA), have been demonstrated. Limited data assessing the efficacy of the LAMA umeclidinium (UMEC) added to ICS/LABA are available. The aim of this study is to evaluate the efficacy and safety of UMEC added to ICS/LABAs in patients with moderate-to-very-severe COPD. This is a multicentre, randomised, double-blind, parallel-group study. Patients were symptomatic (modified Medical Research Council Dyspnoea Scale score ⩾2), despite receiving ICS/LABA (fluticasone propionate/salmeterol (FP/SAL, branded) 500/50 mcg, budesonide/formoterol (BD/FOR, branded) 200/6 mcg or 400/12 mcg, or other ICS/LABAs) ⩾30 days before the run-in (7±2 days). Patients were randomised 1:1 to once-daily UMEC 62.5 mcg or placebo (PBO), added to twice-daily open-label ICS/LABA for 12 weeks. Primary end point was trough forced expiratory volume in 1 s (FEV1) at Day 85; secondary end point was weighted mean (WM) 0-6 h FEV1 at Day 84; other end points included COPD Assessment Test (CAT) score and Transition Dyspnoea Index (TDI) score. Adverse events (AEs) were investigated. In the UMEC+ICS/LABA and PBO+ICS/LABA groups, 119 and 117 patients were randomised, respectively. Patients received FP/SAL (40%), BD/FOR (43%) and other ICS/LABAs (17%). UMEC+ICS/LABA resulted in significant improvements in trough FEV1 (Day 85) and in WM 0-6 h FEV1 (Day 84) versus PBO+ICS/LABA (difference: 123 and 148 ml, respectively, both P<0.001). Change from baseline for UMEC+ICS/LABA versus PBO+ICS/LABA was significantly different for CAT score at Day 84 (-1.31, P<0.05), but not for TDI score (0.40, P=0.152). AE incidence was similar with UMEC+ICS/LABA (38%) and PBO+ICS/LABA (42%). UMEC+ICS/LABA improved lung function and CAT score in patients with symptomatic COPD versus PBO+ICS/LABA (ClinicalTrials.gov NCT02257372).

RESUMO

BACKGROUND: Treatment with long-acting ß2-agonists (LABAs) and long-acting muscarinic antagonists (LAMAs) for chronic obstructive pulmonary disease (COPD) is standard, but response varies. We investigated genetic association with treatment response to umeclidinium (UMEC, a LAMA), vilanterol (VI, a LABA), and combination therapy. METHODS: Data from 17 clinical trials (N = 6075) in patients with COPD receiving once-daily UMEC/VI (125/25mcg or 62.5/25mcg), UMEC (125 or 62.5mcg), VI (25mcg) or placebo were used. Genetic association with change from baseline in trough forced expiratory volume in 1 s (FEV1) ∼24 h post-dosing was assessed for: (i) 3 ß2-adrenoceptor (ADRB2) gene variants; (ii) 298 single-nucleotide polymorphisms (SNPs) with prior evidence of associations; (iii) human leukocyte antigen (HLA) alleles and (iv) genome-wide association study (GWAS) SNPs. Other endpoints were (i) reversibility at screening; and at baseline: (ii) FEV1; (iii) forced vital capacity (FVC), and (iv) FEV1/FVC ratio. Using linear regression, the inverse normal transformed residuals were pooled together, first across treatment group, then across studies for each monotherapy, then combination therapy and finally for every treated patient. RESULTS: Of 6075 patients, 1849 received UMEC/VI, 1390 received UMEC, 1795 received VI, and 1041 received placebo. None of the ADRB2 variants, HLA alleles or GWAS variants tested were associated with treatment response or baseline endpoints. Four SNPs in FAM13A (rs7671167, rs2869967, rs1964516, rs1903003) were significantly associated with baseline FEV1/FVC ratio (p < 3 × 10(-5)) after adjusting for multiple testing. CONCLUSIONS: No genetic association was found with treatment response to UMEC or VI when administered as monotherapies or in combination.

RESUMO

BACKGROUND: Canine chronic bronchitis (CCB) results in cough lasting ≥2 months and airway inflammation. Adverse effects include risk of secondary infection associated with lifelong corticosteroid administration and prompt investigation into alternative therapies. Neurogenic pathways mediated by tachykinins that bind neurokinin (NK) 1 receptors may induce cough and airway inflammation. Maropitant, a NK-1 receptor antagonist, has been advocated for treatment of CCB based on anecdotal improvement, but without scientific evidence. HYPOTHESIS/OBJECTIVES: Maropitant will blunt clinical signs and airway inflammation associated with CCB. ANIMALS: Client-owned dogs (n = 8) with cough >2 months, thoracic radiographic evidence of airway disease and sterile airway inflammation (>7% non-degenerate neutrophils, >7% eosinophils or both) on bronchoalveolar lavage (BAL) enrolled. METHODS: Maropitant (2 mg/kg) administered q48h for 14 days. Study endpoints included client perception of clinical signs (surveys at baseline and 14 days, and visual analogue scale [VAS] at baseline, 7, and 14 days), and BAL % neutrophils and eosinophils (baseline and 14 days). One-way repeated measures ANOVA (VAS) and Wilcoxon-signed rank-sum tests (BAL cells, cough frequency) used with P < .05 considered significant. RESULTS: Maropitant significantly decreased cough frequency (P < .001) and VAS scores (P = .005). No differences in BAL % neutrophils or % eosinophils noted with treatment (P = .279 and P = .382, respectively). CONCLUSIONS AND CLINICAL IMPORTANCE: Preliminary results suggest that although maropitant may have antitussive properties leading to perceived clinical improvement, its failure to diminish airway inflammation makes it unsuitable for treatment of CCB. Future studies could evaluate maropitant as a cough suppressant for other respiratory disorders in dogs.

RESUMO

A number of new agents for the management of chronic obstructive pulmonary disease (COPD) are at different stages of development, including several inhaled long-acting antimuscarinics (LAMA). Long-acting bronchodilators are considered to be central to the management of COPD due to the evidence supporting their efficacy and safety. Umeclidinium, a LAMA, has recently been approved for the maintenance treatment of moderate to very severe COPD in a number of countries. This comprehensive review and pooled meta-analysis provides detailed information about the efficacy and safety of this agent. The pharmacokinetics and pharmacodynamics of umeclidinium observed in phase I and II studies support its once-daily administration. Umeclidinium is rapidly cleared from blood, and renal or hepatic impairment do not lead to significant changes in drug disposition. A pooled analysis of phase III and comparative studies of umeclidinium in patients with moderate to very severe COPD showed significant improvement in lung function measures, including trough forced expiratory volume in 1 s (FEV1), as well as in acute exacerbations of COPD, dyspnea, and quality of life. Adverse effects, including known anticholinergic effects, were uncommon with umeclidinium. Limited data suggest the efficacy of umeclidinium is similar to that of tiotropium. Umeclidinium is administered as a dry powder inhaler, provides adequate lung delivery in patients with moderate to very severe airflow obstruction, and appears to be easily used by patients. Umeclidinium provides a safe and effective option as an inhaled LAMA for the management of COPD.

RESUMO

Chronic obstructive pulmonary disease (COPD) affects around 64 million people worldwide and is the fourth leading cause of death.(1) It is thought that 3 million people have COPD in the UK, with about 900,000 having been diagnosed and an estimated 2.1 million with disease that remains undiagnosed.(2) In addition, premature mortality from COPD in the UK is almost double the European average and as a result there has been considerable focus on improving outcomes for patients.(3)One of the options for maintenance pharmacological treatment of COPD is a long-acting muscarinic antagonist (LAMA).(4) DTB has previously reviewed three inhaled LAMAs licensed in the UK for use by people with COPD: tiotropium and ▼glycopyrronium (both administered once daily), and ▼aclidinium bromide (administered twice daily).(5-8) ▼Umeclidinium bromide (Incruse) is another once daily LAMA, delivered using the Ellipta inhaler device, and is indicated as maintenance bronchodilator treatment to relieve symptoms in adult patients with COPD.(9) Here we review the evidence for its use in the management of COPD.
