On 1 March 2020, changes were made to the PBS listing of fluticasone furoate with umeclidinium and vilanterol (Trelegy Ellipta) for chronic obstructive pulmonary disease (COPD). The PBAC found that triple therapy had greater efficacy than the comparator, LAMA + LABA, but also an increased incidence of pneumonia and oral candidiasisĪs a result the PBAC considered that the appropriate place of triple therapy was after inadequate control was experienced with LAMA + LABA or ICS + LABA.Patients must have experienced at least one severe COPD exacerbation (requiring hospitalisation), or ≥ 2 moderate exacerbations in the previous 12 months. < 50% threshold removal was also accompanied by strengthening of the clinical criteria The change aims to ensure that removal of the FEV 1 threshold does not undermine the importance of spirometry in COPD diagnosis. The role of spirometry for COPD diagnosis was included in the triple therapy PBS listing.Threshold lacks precision to be used clinically as a predictor of exacerbations or mortality in patients with COPD. The FEV 1 threshold removal made the PBS listings consistent with recent evidence.The COPD FDC inhalers include triple therapy (Trelegy Ellipta) and all ICS + LABAs. On 1 March 2020, the FEV 1 Paired inspiratory-expiratory chest CT scans to assess for small airways disease in COPD. Association between functional small airway disease and FEV1 decline in chronic obstructive pulmonary disease. Small airways disease in mild and moderate chronic obstructive pulmonary disease: a cross-sectional study. The pathology of small airways disease in COPD: historical aspects and future directions. Higham A, Quinn AM, Cançado JED, Singh D. X-ray computed dry powder inhalers inhaled corticosteroid long-acting beta2 agonist long-acting muscarinic antagonist metered dose inhalers tomography. This is consistent with the extrafine formulation of BDP/FF/GB. Peripheral (small airways) deposition of all three components (ICS, LABA, and LAMA) was higher from BDP/FF/GB than from FluF/VI/UMEC, based on profiles from patients with moderate to very severe COPD. Furthermore, the ratios of central to peripheral deposition for all three components of BDP/FF/GB were <1, indicating greater peripheral than central deposition (0.48☐.13, 0.48☐.13 and 0.49☐.13 for BDP, FF and GB, respectively 1.96☐.84, 0.97☐.34 and 1.20☐.48 for FluF, VI and UMEC, respectively). Peripheral deposition of all three components was higher with BDP/FF/GB than FluF/VI/UMEC. For intrathoracic deposition (as a percentage of the emitted dose), deposition of the ICS component was higher from BDP/FF/GB than FluF/VI/UMEC the two triple therapies had similar performance for both the LABA component and the LAMA component. HRCT scan data from 20 patients with COPD were included in these analyses, who had post-bronchodilator forced expiratory volume in 1 second (FEV 1) ranging from 19.3% to 66.0% predicted. Lung deposition was estimated in-silico using functional respiratory imaging, a validated technique that uses aerosol delivery performance profiles, patients' high-resolution computed tomography (HRCT) lung scans, and patient-derived inhalation profiles to simulate aerosol lung deposition. This study evaluated the lung deposition of the inhaled corticosteroid (ICS), long-acting β 2-agonist (LABA), and long-acting muscarinic antagonist (LAMA) components of these two SITTs. Two single-inhaler triple therapy (SITT) combinations are currently approved for the maintenance treatment of COPD: extrafine formulation beclomethasone dipropionate/formoterol fumarate/glycopyrronium bromide (BDP/FF/GB), and non-extrafine formulation fluticasone furoate/vilanterol/umeclidinium (FluF/VI/UMEC). There is a clear correlation between small airways dysfunction and poor clinical outcomes in patients with chronic obstructive pulmonary disease (COPD), and it is therefore important that inhalation therapy (both bronchodilator and anti-inflammatory) can deposit in the small airways.
