Bronchodilatory effect of inhaled budesonide/formoterol and budesonide/salbutamol in acute asthma: a double-blind, randomized controlled trial.

ABSTRACT: There are no published studies that have compared bronchodilatory effect of inhaled budesonide/formoterol combination with budesonide/salbutamol delivered by metered dose inhaler with a spacer in acute exacerbation of asthma in children. We, therefore, compared the bronchodilatory effects of inhaled budesonide/formoterol (dose: 200 ?g and 12 ?g respectively) combination with budesonide (200 ?g)/salbutamol (200 ?g) administered by metered dose inhaler and spacer in children of 5-15 years with mild acute exacerbation of asthma [Modified Pulmonary Index Score (MPIS) between 6-8] in this double-blind, randomized controlled trial. The primary outcome was FEV1 (% predicted) in the two groups at 1, 5, 15, 30, 60 min after administration of the study drug.We did not observe any significant differences in the % predicted FEV1 and MPIS between formoterol and salbutamol at various time points from 1 min to 60 min post drug administration. There was significant improvement in FEV1 (% predicted) from baseline in both the groups as early as 1 min after drug administration.Salbutamol or formoterol delivered along with inhaled corticosteroid by metered dose inhaler with spacer in children between 5-15 years of age with mild acute exacerbation of asthma had similar bronchodilatory effects.ClinicalTrials.gov: NCT00900874.

Project description:BackgroundThe budesonide/formoterol combination is successfully used for fast relief of asthma symptoms in addition to its use as maintenance therapy. The temporarily increased corticosteroid dose during increasing inhaler use for symptom relief is likely to suppress any temporary increase in airway inflammation and may mitigate or prevent asthma exacerbations. The relative contribution of the budesonide and formoterol components to the improved asthma control is unclear.MethodsThe acute protective effect of inhaled budesonide was tested in a model of temporarily increased airway inflammation with repeated indirect airway challenges, mimicking an acute asthma exacerbation. A randomised, double-blind, cross-over study design was used. Asthmatic patients (n = 17, mean FEV1 95% of predicted) who previously demonstrated a > or = 30% fall in forced expiratory volume in 1 second (FEV1) after inhaling adenosine 5'-monophosphate (AMP), were challenged on four consecutive test days, with the same dose of AMP (at 09:00, 12:00 and 16:00 hours). Within 1 minute of the maximal AMP-induced bronchoconstriction at 09:00 hours, the patients inhaled one dose of either budesonide/formoterol (160/4.5 microg), formoterol (4.5 microg), salbutamol (2 x 100 microg) or placebo. The protective effects of the randomised treatments were assessed by serial lung function measurements over the test day.ResultsIn the AMP provocations at 3 and 7 hours after inhalation, the budesonide/formoterol combination provided a greater protective effect against AMP-induced bronchoconstriction compared with formoterol alone, salbutamol and placebo. In addition all three active treatments significantly increased FEV1 within 3 minutes of administration, at a time when inhaled AMP had induced the 30% fall in FEV1.ConclusionsA single dose of budesonide/formoterol provided a greater protective effect against inhaled AMP-induced bronchoconstriction than formoterol alone, both at 3 and at 7 hours after inhalation. The acute protection against subsequent bronchoconstrictor stimuli such as inhaled AMP and the rapid reversal of airway obstruction supports the use of budesonide/formoterol for both relief and prevention in the treatment of asthma.

Project description:BackgroundBudesonide and formoterol (BF) Spiromax® is a dry powder inhaler designed to deliver BF with maximum ease of use for patients with asthma or chronic obstructive pulmonary disease.MethodsA phase 3b, 12-week, multicenter, double-blind, double-dummy, randomized, controlled trial in patients (≥12 years) with persistent asthma.Primary objectiveto demonstrate non-inferiority of twice-daily BF Spiromax 160/4.5 mcg to BF Turbuhaler® 200/6 mcg in change from baseline in weekly average of daily trough morning peak expiratory flow (PEF). Secondary endpoints included: Patient Satisfaction and Preference Questionnaire scores, change from baseline in evening PEF, trough forced expiratory volume in one second, percentage of symptom-free and rescue-free 24-hour periods, and safety.ResultsThe analysis was based on the per-protocol population (BF Spiromax, n = 290; BF Turbuhaler, n = 284). The least squares mean change from baseline to week 12 in morning PEF was: BF Spiromax, 18.8 L/min and BF Turbuhaler, 21.8 L/min. Non-inferiority of BF Spiromax vs BF Turbuhaler was demonstrated (the lower limit of the 95% two-sided confidence interval was -9.02 L/min, which is greater than -15 L/min [the criteria specified for non-inferiority]). The mean difference in the total performance domains scores for BF Spiromax vs BF Turbuhaler were 0.248 at baseline and 0.353 at week 12 (both, p <0.001), indicating statistical superiority for BF Spiromax. No statistical or numerical differences were recorded in the total convenience domain score between the two devices. Scores for 'device preference' and 'willingness to continue' supported BF Spiromax at baseline and at week 12 (p = 0.0005 vs BF Turbuhaler). No significant between-group differences were observed in the other secondary efficacy endpoints. Both treatments were well tolerated, with no significant differences in adverse events or asthma exacerbations.ConclusionsThis study demonstrates the non-inferiority of BF Spiromax vs BF Turbuhaler in patients (≥12 years) with asthma. More patients preferred the Spiromax device over Turbuhaler for its performance, and were willing to continue therapy with BF Spiromax beyond the 12-week study period.Trial registrationNCT01803555; February 28, 2013.

Project description:BACKGROUND:Traditionally inhaled treatment for asthma has been considered as preventer and reliever therapy. The combination of formoterol and budesonide in a single inhaler introduces the possibility of using a single inhaler for both prevention and relief of symptoms (single inhaler therapy). OBJECTIVES:The aim of this review is to compare formoterol and corticosteroid in single inhaler for maintenance and relief of symptoms with inhaled corticosteroids for maintenance and a separate reliever inhaler. SEARCH STRATEGY:We last searched the Cochrane Airways Group trials register in September 2008. SELECTION CRITERIA:Randomised controlled trials in adults and children with chronic asthma. DATA COLLECTION AND ANALYSIS:Two review authors independently assessed studies for inclusion and extracted the characteristics and results of each study. Authors or manufacturers were asked to supply unpublished data in relation to primary outcomes. MAIN RESULTS:Five studies on 5,378 adults compared single inhaler therapy with current best practice, and did not show a significant reduction in participants with exacerbations causing hospitalisation (Peto OR 0.59; 95% CI 0.24 to 1.45) or treated with oral steroids (OR 0.83; 95% CI 0.66 to 1.03). Three of these studies on 4281 adults did not show a significant reduction in time to first severe exacerbation needing medical intervention (HR 0.96; 95% CI 0.85 to 1.07). These trials demonstrated a reduction in the mean total daily dose of inhaled corticosteroids with single inhaler therapy (mean reduction ranged from 107 to 267 micrograms/day, but the trial results were not combined due to heterogeneity). The full results from four further studies on 4,600 adults comparing single inhaler therapy with current best practice are awaited.Three studies including 4,209 adults compared single inhaler therapy with higher dose budesonide maintenance and terbutaline for symptom relief. No significant reduction was found with single inhaler therapy in the risk of patients suffering an asthma exacerbation leading to hospitalisation (Peto OR 0.56; 95% CI 0.28 to 1.09), but fewer patients on single inhaler therapy needed a course of oral corticosteroids (OR 0.54; 95% CI 0.45 to 0.64). These results translate into an eleven month number needed to treat of 14 (95% CI 12 to 18), to prevent one patient being treated with oral corticosteroids for an exacerbation. The run-in for these studies involved withdrawal of long-acting beta(2)-agonists, and patients were recruited who were symptomatic during run-in.One study included children (N = 224), in which single inhaler therapy was compared to higher dose budesonide. There was a significant reduction in participants who needed an increase in their inhaled steroids with single inhaler therapy, but there were only two hospitalisations for asthma and no separate data on courses of oral corticosteroids. Less inhaled and oral corticosteroids were used in the single inhaler therapy group and the annual height gain was also 1 cm greater in the single inhaler therapy group, [95% CI 0.3 to 1.7 cm].There was no significant difference found in fatal or non-fatal serious adverse events for any of the comparisons. AUTHORS' CONCLUSIONS:Single inhaler therapy can reduce the risk of asthma exacerbations needing oral corticosteroids in comparison with fixed dose maintenance inhaled corticosteroids. Guidelines and common best practice suggest the addition of regular long-acting beta(2)-agonist to inhaled corticosteroids for uncontrolled asthma, and single inhaler therapy has not been demonstrated to significantly reduce exacerbations in comparison with current best practice, although results of five large trials are awaiting full publication. Single inhaler therapy is not currently licensed for children under 18 years of age in the United Kingdom.

Project description:Rationale: In the phase III, 52-week ETHOS (Efficacy and Safety of Triple Therapy in Obstructive Lung Disease) trial in chronic obstructive pulmonary disease (COPD) (NCT02465567), triple therapy with budesonide/glycopyrrolate/formoterol fumarate (BGF) significantly reduced all-cause mortality compared with glycopyrrolate/formoterol fumarate (GFF). However, 384 of 8,509 patients were missing vital status at Week 52 in the original analyses.Objectives: To assess the robustness of the ETHOS mortality findings after additional data retrieval for patients missing Week 52 vital status in the original analyses.Methods: Patients with moderate to very severe COPD and prior history of exacerbation received twice-daily dosing with 320/18/9.6 μg of BGF (BGF 320), 160/18/9.6 μg of BGF (BGF 160), 18/9.6 μg of GFF, or 320/9.6 μg of budesonide/formoterol fumarate (BFF) (all delivered via a single metered-dose Aerosphere inhaler). Time to death (all-cause) was a prespecified secondary endpoint.Measurements and Main Results: In the final retrieved dataset, which included Week 52 vital status for 99.6% of the intent-to-treat population, risk of death with BGF 320 was significantly lower than GFF (hazard ratio, 0.51; 95% confidence interval, 0.33-0.80; unadjusted P = 0.0035). There were no significant differences in mortality when comparing BGF 320 with BFF (hazard ratio, 0.72; 95% confidence interval, 0.44-1.16; P = 0.1721), nor were significant differences observed when comparing BGF 160 against either dual comparator. Results were similar when the first 30, 60, or 90 days of treatment were excluded from the analysis. Deaths from cardiovascular causes occurred in 0.5%, 0.8%, 1.4%, and 0.5% of patients in the BGF 320, BGF 160, GFF, and BFF groups, respectively.Conclusions: Using final retrieved vital status data, triple therapy with BGF 320 reduced the risk of death compared with GFF, but was not shown to significantly reduce the risk of death compared with BFF, in patients with COPD. Triple therapy containing a lower dose of inhaled corticosteroid (BGF 160) was not shown to significantly reduce the risk of death compared with the dual therapy comparators.

Project description:Background: Severe malaria is a leading cause of acquired neurodisability in Africa and is associated with reduced nitric oxide (NO) bioavailability. A neuroprotective role for inhaled NO has been reported in animal studies, and administration of inhaled NO in preterm neonates with respiratory distress syndrome is associated with a 47% reduced risk of cognitive impairment at two years of age.Methods: A randomized double-blind placebo-controlled trial of inhaled NO versus placebo as an adjunctive therapy for severe malaria was conducted in Uganda between 2011 and 2013. Children received study gas for a maximum 72 hours (inhaled NO, 80 parts per million; room air placebo). Neurocognitive testing was performed on children<5 years at 6 month follow-up. The neurocognitive outcomes assessed were overall cognition (a composite of fine motor, visual reception, receptive language, and expressive language), attention, associative memory, and the global executive composite. Main outcomes were attention, associative memory, and overall cognitive ability.Results: Sixty-one children receiving iNO and 59 children receiving placebo were evaluated. Forty-two children (35.0%) were impaired in at least one neurocognitive domain. By intention-to-treat analysis, there were no differences in unadjusted or unadjusted age-adjusted z-scores for overall cognition (? (95% CI): 0.26 (-0.19, 0.72), p = 0.260), attention (0.18 (-0.14, 0.51), p = 0.267), or memory (0.14 (-0.02, 0.30), p = 0.094) between groups by linear regression. Children receiving inhaled NO had a 64% reduced relative risk of fine motor impairment than children receiving placebo (relative risk, 95% CI: 0.36, 0.14-0.96) by log binomial regression following adjustment for anticonvulsant use.Conclusions: Severe malaria is associated with high rates of neurocognitive impairment. Treatment with inhaled NO was associated with reduced risk of fine motor impairment. These results need to be prospectively validated in a larger study powered to assess cognitive outcomes in order to evaluate whether strategies to increase bioavailable NO are neuroprotective in children with severe malaria.Trial registration: ClinicalTrials.gov Identifier: NCT01255215.

Project description:Background:To evaluate the effects of fluticasone furoate on the hypothalamic-pituitary-adrenocortical axis, and the safety and tolerability of fluticasone furoate treatment in children with asthma. Methods:This was a randomized, double-blind, placebo-controlled, multicenter, stratified, parallel-group, non-inferiority study of fluticasone furoate 50 µg inhalation powder administered once daily. The study enrolled children (aged 5-11 years inclusive) with a documented diagnosis of asthma for ??6 months and a Childhood Asthma Control Test score of >?19. After a 7-14-day run-in period, eligible subjects were stratified by age and randomized to fluticasone furoate 50 µg once daily or placebo once daily via ELLIPTA for 6 weeks. The primary endpoint was the change from baseline (expressed as a ratio) in 0-24-h weighted mean serum cortisol at the end of the treatment period. Results:Fifty-six randomized subjects received fluticasone furoate 50 µg once daily and 55 received placebo. The primary analysis was performed in the serum cortisol population (n?=?104) and demonstrated that fluticasone furoate 50 µg once daily was non-inferior to placebo (ratio?=?0.93; 95% confidence interval 0.8096, 1.0620), as the lower limit of the 95% confidence interval for the geometric mean treatment ratio of fluticasone furoate 50 µg once daily versus placebo was greater than 0.80. Findings from the intent-to-treat population (n?=?111) were similar. Conclusions:Six weeks of treatment with inhaled fluticasone furoate 50 µg once daily had no clinically relevant effect on the hypothalamic-pituitary-adrenocortical axis function of children, as measured by 24-h serum cortisol profiles. The primary analysis showed that fluticasone furoate 50 µg once daily was non-inferior to placebo. Fluticasone furoate 50 µg once daily was well tolerated and no new safety concerns emerged during the study. Trial registration:This study is registered in ClinicalTrials.gov (NCT02483975). Date of submission: 25 June 2015.
