Triple Therapy with Mometasone/Indacaterol/Glycopyrronium or Doubling the ICS/LABA Dose in GINA Step 4: IRIDIUM Analyses.

INTRODUCTION: GINA guidelines recommend increasing the dose of inhaled corticosteroids (ICS) as a step-up option for patients with inadequately controlled asthma at GINA step 4 [inadequately controlled asthma on medium-dose ICS/long-acting beta-2 agonist (LABA)]. The aim of this study was to compare the efficacy and safety of long-acting muscarinic antagonists (LAMA) add-on to medium-dose ICS/LABA in patients at GINA 2022 step 4. METHODS: This post hoc analysis of the IRIDIUM study evaluated the change from baseline in trough forced expiratory volume (FEV1 ) in patients receiving medium-dose MF/IND/GLY versus high-dose MF/IND and high-dose FLU/SAL at Week 26. Other outcomes included improvement in lung functions [peak expiratory flow (PEF), forced vital capacity (FVC), forced expiratory flow between 25% and 75% of the FVC (FEF)25-75%)], asthma control [Asthma Control Questionnaire (ACQ-7)], responder analysis (≥ 0.5 unit improvement in ACQ-7), and reduction in asthma exacerbations at Weeks 26 and 52. RESULTS: A total of 1930 patients were included in this analysis. Medium-dose MF/IND/GLY improved trough FEV1 versus high-dose MF/IND (Δ 41 mL; 95% CI - 7-90) and high-dose FLU/SAL (Δ 88 mL; 95% CI 39-137) at Week 26 which were sustained until Week 52. Exacerbation rates were 16% lower with medium-dose MF/IND/GLY versus high-dose MF/IND for all (mild, moderate, and severe) exacerbations and 21-30% lower versus high-dose FLU/SAL for all (mild, moderate, and severe), moderate or severe, and severe exacerbations over 52 weeks. Further improvements in other lung functions were observed with medium-dose MF/IND/GLY. No new safety signals were identified. CONCLUSION: Medium-dose MF/IND/GLY improved lung function and reduced asthma exacerbations compared to high-dose ICS/LABA and may be an undervalued option in patients at GINA 2022 step 4.

Efficacy of once-daily, single-inhaler, fixed-dose combination of mometasone/indacaterol/glycopyrronium in patients with asthma with or without persistent airflow limitation: Post hoc analysis from the IRIDIUM study.

BACKGROUND: A novel, once-daily, fixed-dose combination of mometasone furoate/indacaterol acetate/glycopyrronium bromide (MF/IND/GLY) delivered via Breezhaler® is the first inhaled corticosteroid/long-acting ꞵ2-agonist/long-acting muscarinic antagonist (ICS/LABA/LAMA) therapy approved for the maintenance treatment of asthma in adults inadequately controlled on ICS/LABA combination. In patients with asthma and persistent airflow limitation (PAL), maximal treatment, especially with combination is suggested. This post hoc analysis of data from the IRIDIUM study assessed the efficacy of MF/IND/GLY in asthma patients with and without PAL. METHODS: Patients with post-bronchodilator FEV1 ≤80% of predicted and FEV1/FVC ratio of ≤0.7 were categorised as PAL subgroup and the remaining as the non-PAL subgroup. Lung function parameters (FEV1, PEF, and FEF25%-75%) and annualised asthma exacerbations rates were evaluated in both subgroups across the treatment arms: once-daily high-dose MF/IND/GLY (160/150/50 µg), high-dose MF/IND (320/150 µg) and twice-daily high-dose fluticasone/salmeterol (FLU/SAL; 500/50 µg). RESULTS: Of the 3092 randomised patients, 64% (n = 1981) met the criteria for PAL. Overall, there was no evidence of treatment difference between PAL and non-PAL subgroups (interaction P-value for FEV1, FEF25%-75%, PEF, moderate or severe exacerbations, severe exacerbations and all exacerbations were 0.42, 0.08, 0.43 0.29, 0.35 and 0.12, respectively). In the PAL subgroup, high-dose MF/IND/GLY versus high-dose MF/IND and high-dose FLU/SAL improved trough FEV1 (mean difference: 102 mL [P < 0.0001] and 137 mL [P < 0.0001]) and reduced moderate or severe (16% and 32%), severe (25% and 39%) and all exacerbations (19% and 38%), respectively. CONCLUSIONS: Once-daily fixed-dose MF/IND/GLY was efficacious in asthma patients with and without persistent airflow limitation.

Efficacy and safety of once-daily QVA149 compared with twice-daily salmeterol-fluticasone in patients with chronic obstructive pulmonary disease (ILLUMINATE): a randomised, double-blind, parallel group study.

BACKGROUND: QVA149 is an inhaled fixed-dose combination therapy under development for the treatment of chronic obstructive pulmonary disease (COPD). It combines indacaterol (a longacting ß2-agonist) with glycopyrronium (a longacting muscarinic antagonist) as a dual bronchodilator. We aimed to compare the efficacy, safety, and tolerability of QVA149 versus salmeterol-fluticasone (SFC) over 26 weeks in patients with moderate-to-severe COPD. METHODS: In this multicentre double-blind, double-dummy, parallel-group study, 523 patients (age 40 years or older, Global Initiative for Chronic Obstructive Lung Disease [GOLD] stages II-III, without exacerbations in the previous year) were randomly assigned (1:1; via automated, interactive response technology and stratified for smoking status) to once-daily QVA149 110/50 µg or twice-daily SFC 50/500 µg for 26 weeks. Efficacy was assessed in the full analysis set (randomised patients who received at least one dose of study drug); safety was assessed in all patients who received at least one dose of study drug. The primary endpoint was to demonstrate the superiority of QVA149 compared with SFC for the standardised area under the curve from 0 to 12 h post dose for forced expiratory volume in 1 second (FEV1 AUC0-12h) after 26 weeks of treatment. This trial was registered at ClinicalTrial.gov, NCT01315249. FINDINGS: Between March 25, 2011, and March 12, 2012, 259 patients were randomly assigned to receive QVA149 and 264 to receive SFC. At week 26, FEV1 AUC0-12h was significantly higher with QVA149 than with SFC (treatment difference 0·138 L; 95% CI 0·100-0·176; p<0·0001). Overall incidence of adverse events (including COPD exacerbations) was 55·4% (143 of 258) for the QVA149 group and 60·2% (159 of 264) for the SFC group. Incidence of serious adverse events was similar between treatment groups (QVA149, 13 of 258 [5·0%]; SFC 14 of 264 [5·3%]); COPD worsening was the most frequent serious adverse event (one of 13 [0·4%] and three of 14 [1·1%], respectively). INTERPRETATION: Once-daily QVA149 provides significant, sustained, and clinically meaningful improvements in lung function versus twice-daily SFC, with significant symptomatic benefit. These results indicate the potential of dual bronchodilation as a treatment option for non-exacerbating symptomatic COPD patients. FUNDING: Novartis Pharma AG.

Analysis of chronic obstructive pulmonary disease exacerbations with the dual bronchodilator QVA149 compared with glycopyrronium and tiotropium (SPARK): a randomised, double-blind, parallel-group study.

BACKGROUND: We evaluated the effect of dual, longacting inhaled bronchodilator treatment on exacerbations in patients with severe and very severe chronic obstructive pulmonary disease (COPD). METHODS: In this parallel-group study, 2224 patients (aged ≥40 years, Global Initiative for Chronic Obstructive Lung Disease stages III-IV, and one or more moderate COPD exacerbation in the past year) were randomly assigned (1:1:1; via interactive voice response or web system; stratified for smoking status) to once-daily QVA149 (fixed-dose combination of indacaterol 110 µg and glycopyrronium 50 µg), glycopyrronium 50 µg, or tiotropium 18 µg for 64 weeks. Assignment to QVA149 and glycopyrronium was double-blind; tiotropium was open-label. Efficacy was assessed in all patients randomly assigned to treatment groups who received at least one dose of study drug; safety was assessed in all patients who received at least one dose whether or not they were assigned to a group. The primary objective was to show superiority of QVA149 versus glycopyrronium for rate of moderate to severe COPD exacerbations (defined by worsening symptoms and categorised by treatment requirements) during treatment. This completed trial is registered at ClinicalTrials.gov, NCT01120691. FINDINGS: Between April 27, 2010, and July 11, 2012, 741 patients were randomly assigned to receive QVA149, 741 to receive glycopyrronium, and 742 to receive tiotropium (729, 739, and 737 patients, respectively, analysed for efficacy). QVA149 significantly reduced the rate of moderate to severe exacerbations versus glycopyrronium by 12% (annualised rate of exacerbations 0·84 [95% CI 0·75-0·94] vs 0·95 [0·85-1·06]; rate ratio 0·88, 95% CI 0·77-0·99, p=0·038). Adverse events (including exacerbations) were reported for 678 (93%) of 729 patients on QVA149, 694 (94%) of 740 on glycopyrronium, and 686 (93%) of 737 on tiotropium. Incidence of serious adverse events was similar between groups (167 [23%] patients on QVA149, 179 [24%] on glycopyrronium, and 165 [22%] on tiotropium); COPD worsening was the most frequent serious adverse event (107 [15%] patients on QVA149, 116 [16%] on glycopyrronium, 87 [12%] on tiotropium). INTERPRETATIONS: The dual bronchodilator QVA149 was superior in preventing moderate to severe COPD exacerbations compared with the single longacting antimuscarinic bronchodilator glycopyrronium, with concomitant improvements in lung function and health status. These results indicate the potential of dual bronchodilation as a treatment option for patients with severe and very severe COPD. FUNDING: Novartis Pharma AG.
