Effect of once-daily indacaterol maleate/mometasone furoate on exacerbation risk in adolescent and adult asthma: a double-blind randomised controlled trial.

ABSTRACT: To investigate the safety and efficacy of QMF149, a once-daily, fixed-dose combination of the long-acting ?2-agonist (LABA) indacaterol maleate and inhaled corticosteroid (ICS) mometasone furoate (MF) for the treatment of persistent asthma. The hypothesis was that QMF149 would not increase the risk of serious asthma exacerbations.174 research centres in nine countries.1519 adolescents and adults with persistent asthma who were treated or qualified for treatment with combination LABA/ICS were randomised, and 1508 were included in the intention-to-treat analysis.Patients were randomised to QMF149 (indacaterol maleate 500?µg/MF 400?µg) or MF (400?µg) once daily via Twisthaler inhalation device in a double-blind, parallel-group study for 6-21?months.The primary end point was time to first serious asthma exacerbation (resulting in hospitalisation, intubation or death). The key secondary end point was annual rate of exacerbations requiring systemic corticosteroids.Treatment with QMF149 resulted in no significant difference in time to first serious exacerbation compared to MF (2 (0.3%) vs 6 events (0.8%); difference -0.52 percentage point; 95% CI -1.25 to 0.21, p=0.160, HR=0.31; 95% CI 0.06 to 1.54, p=0.151). QMF149 significantly reduced the annual rate of exacerbations requiring systemic corticosteroids (rate ratio=0.71; 95% CI 0.55 to 0.90, p=0.005). Proportions of patients experiencing adverse events were similar across groups (74.0% in the QMF149 group and 73.4% in the MF group). Serious adverse events occurred in 4% and 5.8% of patients in the QMF149 and MF groups, respectively.No significant difference was observed in the primary outcome of time to first serious asthma exacerbation in patients treated with QMF149 compared with patients treated with MF. Long-term treatment with QMF149 once daily had a favourable safety/efficacy profile in adolescent and adult patients with persistent asthma.ClinicalTrials.gov; NCT00941798.

Project description:BackgroundIndacaterol acetate (IND), a long-acting β2-agonist in combination with mometasone furoate (MF), an inhaled corticosteroid (ICS), is being explored as a once-daily (od) treatment for asthma in children. This study examined the efficacy, safety, and systemic exposure of IND 75 µg and IND 150 µg in children with persistent asthma.MethodsIn this Phase IIb, multicenter, randomized, double-blind, parallel-group study, pediatric patients (aged ≥ 6 to < 12 years) with persistent asthma were randomized (1:1) to receive either IND 75 µg od or IND 150 µg od via Breezhaler® in combination with ICS background therapy. The primary endpoint was change from baseline in pre-dose trough forced expiratory volume in one second (FEV1) after two weeks of treatment.ResultsIn total, 80 patients received IND 75 µg (n = 39) or IND 150 µg (n = 41). The study met its primary endpoint; both doses demonstrated improvements in pre-dose trough FEV1 from baseline to Day 14 (mean change [Δ]: 212 mL, IND 75 µg; 171 mL, IND 150 µg). The secondary spirometry parameters (post-dose FEV1 after 1-h, post-dose forced vital capacity; morning and evening peak expiratory flow) also improved. Overall, 36.1% in IND 75 μg group and 25% patients in IND 150 μg group achieved a decrease from baseline in Pediatric Interviewer-administered Asthma Control Questionnaire score of ≥ 0.5 units. A dose-dependent increase in plasma IND concentration was noted between the two groups. Both IND doses demonstrated an acceptable safety profile.ConclusionsOnce-daily IND 75 μg and IND 150 μg via Breezhaler® in combination with background ICS therapy provided substantial bronchodilation in children with asthma and were well tolerated. Taken together, these clinical and systemic exposure findings support IND 75 μg as the most appropriate dose for evaluation in Phase III trials in combination with MF in pediatric asthma.Trial registrationClinicalTrials.gov (NCT02892019; 08-Sep-2016).

Project description:Background and objectiveClinical evidence suggests no clinically relevant pharmacokinetic interactions between indacaterol (IND), glycopyrronium (GLY) and mometasone furoate (MF). A population pharmacokinetic (popPK) analysis was conducted to identify structural models describing systemic pharmacokinetic profiles of IND, GLY and MF, and estimate the effect of covariates on their pharmacokinetics following inhalation as IND/GLY/MF.MethodsPharmacokinetic data from 698 patients with asthma were pooled from two Phase III studies that evaluated IND/MF medium- (150/160 µg) and high-dose (150/320 µg), IND/GLY/MF medium- (150/50/80 μg) and high-dose (150/50/160 μg), and a device bridging Phase II study with MF. One popPK model was developed each for IND, GLY and MF using a nonlinear mixed-effect modelling approach. Maximal and trough plasma concentrations were compared across formulations and studies, including data for IND/GLY from chronic obstructive pulmonary disease (COPD) patients. The effect of predefined covariates on the pharmacokinetics of components was evaluated using a full covariate modelling approach.ResultsThe final pharmacokinetic models were two-compartment disposition models with first-order elimination and sequential zero-order/first-order absorption (IND), with bolus administration and first-order elimination (GLY), and with mixed zero-order/first-order absorption and first-order elimination (MF). All model parameters were estimated with good precision (% relative standard error: IND and MF ≤25%; GLY <10%). No clinically relevant covariate effect was observed on the pharmacokinetics of IND, GLY and MF. IND and GLY pharmacokinetic profiles were similar across different formulations.ConclusionTwo-compartment popPK models adequately described the pharmacokinetics of IND, GLY and MF. The effect of covariates was not clinically relevant. The pharmacokinetic profiles of MF were comparable for combination products at corresponding medium- or high-dose inhaled corticosteroids. On a population level, the pharmacokinetics of IND and GLY were comparable between patients with asthma and COPD.

Project description:BackgroundTo 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.MethodsThis 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.ResultsFifty-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.ConclusionsSix 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 registrationThis study is registered in ClinicalTrials.gov (NCT02483975).
