摘要
Background Fixed-dose combinations (FDCs) of inhaled corticosteroids (ICS) and long-acting beta(2)-adrenoceptor agonists (LABA) are considered safe and effcacious in asthma management. Most available FDCs require twice-daily dosing to achieve optimum therapeutic effect. The objective of the PALLADIUM study was to assess the efficacy and safety of once-daily FDC of mometasone furoate plus indacaterol acetate (MF-IND) versus mometasone furoate (MF) monotherapy in patients with inadequately controlled asthma. Methods This 52-week, double-blind, triple-dummy, parallel-group, phase 3 study recruited patients from 316 centres across 24 countries. Patients aged 12 to 75 years with a documented diagnosis of asthma for at least 1 year, percentage of predicted FEV, of 50-85%, and an Asthma Control Questionnaire 7 score of at least 1.5 despite treatment with medium-dose or high-dose ICS or low-dose ICS plus LABA were included. A history of asthma exacerbations was not a study requirement. Participants were randomily assigned (1:1:1:1:1) via interactive response technology to receive one of the following treatments for 52 weeks: high-dose MF-IND (320 mu g, 150 mu g) or medium-dose MF-IND (160 mu g, 150 mu g) once daily via Breezhaler; high-dose MF (800 mu g [400 mu g twice daily]) or medium-dose MF (400 mu g once daily) via Twisthaler; or high-dose fluticasone propionate-salmeterol xinafoate (FLU-SAL; 500 mu g, 50 mu g) twice daily via Diskus. Participants received placebo via inhalation through the Breezhaler, Twisthaler, or Diskus devices in the mornings and evenings, as appropriate. The primary endpoint was improvement in trough FEV, with high-dose and medium-dose MF-IND versus respective MF doses from baseline at 26 weeks, analysed in the full analysis set by means of a mixed model for repeated measures. High-dose MF-IND once daily was compared with high-dose FLU-SAL twice daily for non-inferiority on improving trough FEV, at week 26 with a margin of -90 mL using mixed model for repeated measures as one of the secondary endpoints. Safety was assessed in all patients who had received at least one dose of study drug. This study is registered with ClinicalTrials.gov , NCT02554786, and is completed. Findings Between Dec 29, 2015, and May 4, 2018, 2216 patients were randomly assigned (high-dose MF-IND, n=445; medium-dose MF-IND, n=439; high-dose MF, n=442; medium-dose MF, n=444; high-dose FLU-SAL, n=446), of which 1973 (89.0%) completed the study treatment and 234 (10.6%) prematurely discontinued study treatment. High-dose MF-IND (treatment difference [Delta] 132 la [95% CI 88 to 176]; p<0.001) and medium-dose MF-IND (Delta 211 mL [167 to 255]; p<0 .001) showed superiority in improving trough FEV1 over corresponding MF doses from baseline at week 26. High-dose MF-IND was non-inferior to high-dose FLU-SAL in improving trough FEV1 from baseline at week 26 (Delta 36 mL [-7 to 80]; p=0 - 101). Overall, the incidence of adverse events was similar across the treatment groups. Interpretation Once-daily FDC of ICS and LABA (MF-IND) significantly improved lung function over ICS monotherapy (MF) at week 26; high-dose MF-IND was non-inferior to twice-daily combination of ICS and LABA (high-dose FLU-SAL) for improvement in trough FEV,. The combination of MF-IND provides a novel once-daily dry powder option for asthma control. Copyright (C) 2020 Elsevier Ltd. All rights reserved.
