Budesonide/Formoterol Anti-Inflammatory Reliever and Maintenance or Fluticasone Propionate/Salmeterol Plus As-Needed, Short-Acting ?₂ Agonist: Real-World Effectiveness in pAtients without Optimally Controlled asThma (REACT) Study.

ABSTRACT:

Introduction

In the prospective, observational, 16-week REACT study conducted between October 21, 2008 and May 12, 2011, we compared the real-world effectiveness of anti-inflammatory reliever and maintenance therapy with budesonide/formoterol (Symbicort^® Turbuhaler) and maintenance therapy with fixed-dose fluticasone/salmeterol (Seretide^®) plus as-needed, short-acting ?₂ agonists (SABAs) in Taiwanese patients with inadequate asthma control.

Methods

Asthma control was assessed using the five-item Asthma Control Questionnaire (ACQ-5) and standardized pulmonary function testing. Assessments were performed at baseline and at weeks 4-5 and 12-16. Overall, we enrolled 842 patients at 11 clinics, 723 of whom were included in analyses (budesonide/formoterol, 563.3±1.3 ?g/d, n=551; fluticasone/salmeterol, 1013.8±1.4 ?g/d, n=172).

Results

At baseline, 72.5% and 27.5% of all patients had "partly" and "uncontrolled" asthma, respectively. Mean±SD ACQ-5 scores were 1.54±1.06 and 1.46±1.28 in the budesonide/formoterol and fluticasone/salmeterol groups, respectively. ACQ-5 scores significantly improved from baseline (ie, decreased) in both groups at weeks 4 and 16. ACQ-5 difference scores were significantly lower in the budesonide/formoterol group (-0.91±1.11) than the fluticasone/salmeterol group (-0.69±1.27) at the end of the study (p=0.027). Peak expiratory flow rate significantly improved from baseline in the budesonide/formoterol but not the fluticasone/salmeterol group at the end of the study. Severe exacerbation rates and medical resource utilization were comparable between the budesonide/formoterol and fluticasone/salmeterol groups.

Conclusion

Collectively, results indicate the real-world effectiveness of budesonide/formoterol anti-inflammatory reliever and maintenance therapy is better than fixed-dose fluticasone/salmeterol plus as-needed SABA.

Project description:BackgroundImproving patients' health-related quality of life (HRQoL) is recognized as a fundamental part of asthma management. The aims of this study were to evaluate the long-term efficacy (including symptom-free days and exacerbations) and impact on HRQoL of a stable-dose regimen of salmeterol/fluticasone propionate (SAL/FP) and an adjustable maintenance dosing (AMD) regimen of formoterol/budesonide (FOR/BUD) where treatment is adjusted based on symptoms [SAM40056].MethodsA total of 688 outpatients with asthma receiving regular low-dose inhaled corticosteroids (ICS) plus a long-acting beta2-agonist, or medium dose ICS alone participated in this randomized, double-blind, double-dummy, parallel-group, 1-year trial, which was conducted in 91 centers in 15 countries. Patients were randomized to receive 1 inhalation of SAL/FP 50/250 mug BID or 2 inhalations of FOR/BUD 6/200 mug BID during Weeks 1-4. For Weeks 5-52, patients meeting strict continuation criteria for stable asthma at Week 4 received AMD with FOR/BUD or stable-dose SAL/FP.ResultsThe percentage of symptom-free days was significantly greater (58.8% vs 52.1%; p = 0.034) and the annual exacerbation rate was significantly lower (47%; p = 0.008) with stable-dose SAL/FP compared with FOR/BUD AMD. A total of 568 patients completed the Asthma Quality of Life Questionnaire (AQLQ) at least once during the study. The mean change from baseline in AQLQ overall score was numerically greater with SAL/FP than FOR/BUD at week 28 and week 52, but did not reach statistical significance (p = 0.121 at Week 52). However, in a post hoc logistic regression analyses for any AQLQ improvement, significant benefits with SAL/FP were seen at both time points (p = 0.038 and p = 0.009, respectively). The minimally important difference of >/= 0.5-point improvement in AQLQ overall score was achieved by a significantly greater number of patients receiving SAL/FP at Week 28 (68% vs 60%; p = 0.049); a trend for this difference remained at Week 52 (71% vs 65%) (p = 0.205).ConclusionIn this population of patients with persistent asthma, stable-dose SAL/FP resulted in significantly greater increases in symptom-free days, a reduction in exacerbation rates, and provided greater HRQoL benefits compared with FOR/BUD AMD.Trial registrationClinical Trials registration number NCT00479739.

Project description:BackgroundMometasone furoate/formoterol (MF/F) is a novel combination therapy for treatment of persistent asthma. This noninferiority trial compared the effects of MF/F and fluticasone propionate/salmeterol (FP/S) combination therapies on pulmonary function and onset of action in subjects with persistent asthma.MethodsFollowing a 2- to 4-week run-in period with MF administered via a metered-dose inhaler (MDI) 200 μg (delivered as 2 inhalations of MF-MDI 100 μg) twice daily (BID), subjects (aged ≥12 y) were randomized to MF/F-MDI 200/10 μg BID (delivered as 2 inhalations of MF/F-MDI 100/5 μg) or FP/S administered via a dry powder inhaler (DPI) 250/50 μg (delivered as 1 inhalation) BID for 12 weeks. The primary assessment was change from baseline to week 12 in area under the curve for forced expiratory volume in 1 second measured serially for 0-12 hours postdose (FEV1 AUC0-12 h). Secondary assessments included onset of action (change from baseline in FEV1 at 5 minutes postdose on day 1) and patient-reported outcomes.Results722 subjects were randomized to MF/F-MDI (n = 371) or FP/S-DPI (n = 351). Mean FEV1 AUC0-12 h change from baseline at week 12 for MF/F-MDI and FP/S-DPI was 3.43 and 3.24 L × h, respectively (95% CI, -0.40 to 0.76). MF/F-MDI was associated with a 200-mL mean increase from baseline in FEV1 at 5 minutes postdose on day 1, which was significantly larger than the 90-mL increase for FP/S-DPI (P < 0.001). The overall incidence of adverse events during the 12-week treatment period that were considered related to study therapy was similar in both groups (MF/F-MDI, 7.8% [n = 29]; FP/S-DPI, 8.3% [n = 29]).ConclusionsThe results of this 12-week study indicated that MF/F improves pulmonary function and asthma control similar to FP/S with a superior onset of action compared with FP/S. Both drugs were safe, improved asthma control, and demonstrated similar results for other secondary study endpoints.Trial registrationClinicalTrials.gov: NCT00424008.

Project description:BackgroundInhaled corticosteroid use is associated with increased rates of pneumonia in COPD patients. The underlying mechanism is unknown, although recent data suggest that pneumonia is more frequent in patients treated with fluticasone propionate (FP) than budesonide. Macrophages and neutrophils from COPD patients are deficient in clearing bacteria, and this might explain increased bacterial colonization in COPD. Inhaled corticosteroid may further suppress this response; therefore, we examined the effect of FP and budesonide on phagocytosis of common respiratory pathogens by monocyte-derived macrophages (MDMs) and neutrophils.MethodsMDMs from COPD patients (n=20-24) were preincubated with FP or budesonide for 1 or 18 hours, after which phagocytosis of fluorescently labeled inert beads or heat-killed Haemophilus influenzae/Streptococcus pneumoniae were measured fluorimetrically after 1 or 4 hours. Additionally, CXCL8, IL6, and TNF? concentrations in supernatants by ELISA, MDM-scavenger-receptor expression by flow cytometry, and MDM ability to kill bacteria were measured. Neutrophils from COPD patients (n=8) were preincubated with corticosteroids for 1 hour and bacteria phagocytosis measured by flow cytometry.ResultsAfter 1 hour's preincubation, neither corticosteroid altered MDM phagocytosis of beads or H. influenzae; however, budesonide (10-7 M) increased S. pneumoniae phagocytosis by 23% (P<0.05). After 18 hours' preincubation, neither corticosteroid altered MDM phagocytosis of any prey, although H. influenzae phagocytosis by budesonide was significantly greater compared to FP at 10-6 and 10-5 M (P<0.05). The 1-hour preincubation with either corticosteroid inhibited bacteria-induced CXCL8 release (at 10-7 and 10-5 M, P<0.05); however, this effect was lost at 18-hour preincubation. There was no change in receptor expression, bacterial killing, or neutrophil phagocytosis by either corticosteroid.ConclusionThese data suggest that dissolved FP and budesonide do not have an overall effect on MDM or neutrophil phagocytosis of bacteria.

Project description:BackgroundInhaled corticosteroid/long-acting β2-agonist combinations (ICS/LABA) have emerged as first line therapies for chronic obstructive pulmonary disease (COPD) patients with exacerbation history. No randomized clinical trial has compared exacerbation rates among COPD patients receiving budesonide/formoterol combination (BFC) and fluticasone/salmeterol combination (FSC) to date, and only limited comparative data are available. This study compared the real-world effectiveness of approved BFC and FSC treatments among matched cohorts of COPD patients in a large US managed care setting.MethodsCOPD patients (≥40 years) naive to ICS/LABA who initiated BFC or FSC treatments between 03/01/2009-03/31/2012 were identified in a geographically diverse US managed care database and followed for 12 months; index date was defined as first prescription fill date. Patients with a cancer diagnosis or chronic (≥180 days) oral corticosteroid (OCS) use within 12 months prior to index were excluded. Patients were matched 1-to-1 on demographic and pre-initiation clinical characteristics using propensity scores from a random forest model. The primary efficacy outcome was COPD exacerbation rate, and secondary efficacy outcomes included exacerbation rates by event type and healthcare resource utilization. Pneumonia objectives included rates of any diagnosis of pneumonia and pneumonia-related healthcare resource utilization.ResultsMatching of the identified 3,788 BFC and 6,439 FSC patients resulted in 3,697 patients in each group. Matched patients were well balanced on age (mean=64 years), gender (BFC: 52% female; FSC: 54%), prior COPD-related medication use, healthcare utilization, and comorbid conditions. During follow-up, no significant difference was seen between BFC and FSC patients for number of COPD-related exacerbations overall (rate ratio [RR]=1.02, 95% CI=[0.96,1.09], p=0.56) or by event type: COPD-related hospitalizations (RR=0.96), COPD-related ED visits (RR=1.11), and COPD-related office/outpatient visits with OCS and/or antibiotic use (RR=1.01). The proportion of patients diagnosed with pneumonia during the post-index period was similar for patients in each group (BFC =17.3%, FSC =19.0%, odds ratio=0.92 [0.81,1.04], p=0.19), and no difference was detected for pneumonia-related healthcare utilization by place of service.ConclusionThis study demonstrated no difference in COPD-related exacerbations or pneumonia events between BFC and FSC treatment groups for patients new to ICS/LABA treatment in a real-world setting.Trial registrationClinicalTrials.gov identifier NCT01921127 .
