Simplifying COPD Treatment A RESEARCH REVIEW™ SPEAKER SERIES Making Education Easy About the speaker Associate Professor Robert Young Dr Young is a General Physician at Auckland City Hospital. He is a medical graduate of the University of Otago and was awarded a Commonwealth Scholarship which enabled him to graduate from the University of Oxford with a PhD in Molecular Genetics. He has been a Consultant Physician in the Department of Medicine, Auckland City Hospital for the last 25 years and is jointly appointed as Associate Professor in the Faculties of Health and Medical Sciences and the School of Biological Sciences at the University of Auckland. Currently he lectures to medical students and post-graduate science students. His research and clinical interests focus on the primary prevention and early diagnosis of the smoking-related respiratory diseases COPD and lung cancer. He has been the first to show that COPD and lung cancer are linked at a molecular genetic level through overlapping pathogenetic pathways which are activated by smoking in susceptible smokers. ABOUT RESEARCH REVIEW Research Review is an independent medical publishing organisation producing electronic publications in a wide variety of specialist areas. A Research Review Speaker Series is a summary of a speaking engagement by a medical expert. It is made available to health professionals via e-mail or website download to Research Review subscribers or by physical distribution by Research Review or third parties. Research Review has no control over the content of these presentations, which has been developed and presented by the featured expert. Research Review is not responsible for any inaccuracies or errors of fact made by, or opinions of, the speaker. 2023 This publication summarises key points from a breakfast symposium presented by Associate Professor Robert Young at the Rotorua General Practice Conference & Medical Exhibition (GP CME) in June 2023. It discusses the burden of chronic obstructive pulmonary disease (COPD), in particular breathlessness and exacerbations, and the importance of screening for symptoms. Up-to-date recommendations for pharmacological management of COPD are summarised, including new advice from the Global Initiative for Chronic Obstructive Lung Disease (GOLD). Evidence for the use of dual and triple therapy in COPD is then presented. Sponsorship for the symposium was provided by GlaxoSmithKline (GSK). Burden of COPD Chronic obstructive pulmonary disease (COPD) is the third leading cause of death globally, accounting for more than 3 million deaths every year.1 In New Zealand, 15% of the population aged >45 years has COPD, which is approximately 200,000 people.2 More than 6000 new cases of COPD are diagnosed in New Zealand each year, with Māori and Pasifika disproportionately affected.2,3 New Zealand has the fourth highest rate of hospital admissions in adults with asthma and COPD among OECD member countries.4 As a disease, COPD remains under-diagnosed and under-treated.5 In addition to the risks of hospitalisation and mortality, patients with COPD exhibit a clinically meaningful decline in health status, health-related quality of life and prognosis associated with depression and anxiety, poor sleep and lost work days.6-8 Breathlessness has a significant impact on daily activities.9,10 In a pan-European study of 2441 patients, COPD symptoms affected going up and down stairs in 83%, performing heavy household duties in 57%, going shopping in 43% and doing sport or hobbies in 36%.10 Breathlessness in COPD is linked with a downward spiral of deteriorating health status, which starts as the patient avoids physical activity after experiencing dyspnoea.11,12 As the patient becomes more sedentary, physiological deconditioning aggravates their dyspnoea, and further reduces activity.11,12 Exacerbations are an important feature of COPD, and become more frequent and severe as lung function declines.13 They are the most common reason for hospitalisation in patients with COPD,14 and are associated with an increased risk of mortality.15 Exacerbations are a major contribution to the economic burden associated with COPD.16,17 In a Canadian cohort study that followed more than 70,000 patients with COPD for 17 years, 50% of patients died within 4 years of their first hospitalisation for a COPD exacerbation.15 Each severe exacerbation in patients with COPD increases the risk of another event or death, with subsequent exacerbations increasing in severity.15,18 Diagnosis and assessment A diagnosis of COPD should be considered in any individual aged >40 years who presents with breathlessness, wheeze, cough or sputum production, particularly those with a history of smoking.9 The 5-level modified Medical Research Council (mMRC) Dyspnoea Scale may be used to screen for breathlessness (see Table 1).9 Patients with a mMRC score ≥2 should undergo further investigation.5 Grade Symptom complex 0 I only get breathless with strenuous exercise 1 I get short of breath when hurrying on level ground or walking up a slight hill 2 On level ground, I walk slower than other people of the same age because of breathlessness, or I have to stop for breath when walking at my own pace on the level 3 I stop for breath after walking about 100 metres or after a few minutes on level ground 4 I am too breathless to leave the house or I am breathless when dressing or undressing Table 1.

NZMJ 19 February 2021, Vol 134 No 1530 25 ISSN 1175-8716 © NZMA www.nzma.org.nz/journal Global Initiative for Chronic Obstructive Lung Disease (GOLD) 2023 recommendations for pharmacological management of COPD follow the ABE assessment tool, as shown in Figure 2.5 This tool considers the number and severity of exacerbations, as well as mMRC and CAT scores.5 In a simplification from GOLD 2022 recommendations, patient groups C and D have been merged into a single group (E), to recognise the clinical relevance of exacerbations, independent of the level of symptoms.5,19 GOLD now recommends dual bronchodilation with a long-acting muscarinic antagonist (LAMA) plus a long-acting beta2 agonist (LABA) as the cornerstone of treatment for the majority of symptomatic patients with COPD.5 Monotherapy should only be used in patients with few symptoms and a low risk of exacerbations (group A).5 These patients can be treated with either a short-acting or long-acting bronchodilator, however a longacting bronchodilator is preferred except for those with very occasional breathlessness.5 In New Zealand, PHARMAC Special Authority criteria for LAMA/LABA requires that patients are first stabilised on LAMA monotherapy, however, no mandatory time period for stabilisation is specified.20 Use of an inhaled corticosteroid (ICS) plus LABA in COPD is not encouraged by GOLD.5 If there is an indication for an ICS, then triple therapy with an ICS plus LAMA plus LABA is preferred, as this has been shown to be superior to ICS/LABA.5 GOLD guidelines state that patients with COPD who have concomitant asthma should be treated like patients with asthma, in which case use of an ICS is mandatory.5 GOLD 2022 ≥2 moderate exacerbations or ≥1 leading to hospitalisation 0 or 1 moderate exacerbations (not leading to hospital admission) Group C LAMA Group A A bronchodilator mMRC 0–1 CAT <10 GOLD 2023 Group D LAMA or LAMA + LABA or ICS + LABA Group B A long-acting bronchodilator (LABA or LAMA) mMRC ≥2 CAT ≥10 Simplified approach ≥2 moderate exacerbations or ≥1 leading to hospitalisation 0 or 1 moderate exacerbations (not leading to hospital admission) Group E LABA + LAMA Consider LABA+LAMA+ICS if blood eos ≥300 cells/μL Group A A bronchodilator Group B LABA + LAMA mMRC 0–1, CAT <10 mMRC ≥2, CAT ≥10 Figure 2.

Maintenance therapy for patients with ACO usually consists of ICS/LABA in a single inhaler, with the addition of LAMA if needed.9 However, patients with ACO have largely been excluded from clinical trials, meaning that treatment recommendations are based on expert opinion only.9 Maintenance therapy recommendations for patients with COPD, as published in the NZ COPD 2021 guidelines, are summarised in Table 2.9 LABAs LAMAs LAMA/LABA combinations ICS/LABA combinations When treating Start with If needed, move on to COPD without frequent exacerbations LAMA LABA/LAMA COPD with frequent exacerbations LAMA LABA/LAMA (consider ICS/LABA for eosinophilia) then LABA/LAMA/ICS Asthma/COPD overlap ICS/LABA ICS/LABA plus LAMA Table 2.

Incruse Ellipta (umeclidinium bromide 62.5mcg) is a prescription medicine for the regular treatment of COPD. Precautions: Not recommended for use in patients with asthma or for relief of acute symptoms or an acute exacerbation. Use with caution in patients with severe cardiovascular disease, narrow-angle glaucoma or urinary retention. Paradoxical bronchospasm may occur. Before prescribing please review the data sheet at www.medsafe.govt.nz for information on dosage, contraindications, precautions, interactions and adverse effects. Anoro Ellipta (umeclidinium [as bromide] 62.5 mcg, vilanterol [as trifenatate] 25 mcg inhaler) is a prescription medicine for the regular treatment of COPD. Precautions: Not recommended for use in patients with asthma or for relief of acute symptoms or an acute exacerbation. Use with care when coadministering with strong CYP3A4 inhibitors (e.g. ketoconazole) and in patients with severe cardiovascular disease, narrow-angle glaucoma or urinary retention. Paradoxical bronchospasm may occur. Before prescribing please review the data sheet at www.medsafe.govt.nz for information on dosage, contraindications, precautions, interactions and adverse effects. Breo Ellipta (fluticasone furoate 100mcg/vilanterol trifenatate 25mcg) is a prescription medicine for the regular treatment of asthma in adults and adolescents aged 12 years and older and for the regular treatment of COPD in adults with a FEV1<70% predicted normal in patients with an exacerbation history. Before prescribing please review the data sheet for information on dosage, contraindications, precautions, interactions and adverse effects. The data sheet is available at www.medsafe.govt.nz. A separate reliever inhaler may be required. Breo Ellipta is not for the relief of acute symptoms. Seretide (fluticasone propionate/salmeterol xinafoate, available as metered dose inhaler (MDI) 50/25, 125/25, 250/25 mcg per actuation and Accuhaler 100/50 or 250/50 mcg per actuation) is a prescription medicine for the regular treatment of asthma in adults, adolescents and children aged 4 years and over, where use of a combination product (bronchodilator and inhaled corticosteroid) is appropriate. Seretide is also indicated for the symptomatic treatment of adult patients with moderate to severe COPD (prebronchodilator FEV1<60% predicted normal), who have significant symptoms despite bronchodilator therapy. Warnings and Precautions: Not to be initiated in patients during an exacerbation, or if they have unstable or acutely deteriorating asthma. Not for relief of acute symptoms. Physicians should remain vigilant for the possible development of pneumonia in patients with COPD as the clinical features of such infections overlap with the symptoms of COPD exacerbations. Paradoxical bronchospasm may occur after dosing, inhaler/accuhaler should be discontinued and patient assessed. Do not discontinue abruptly due to risk of exacerbation. Use carefully when co-administering strong CYP3A4 inhibitors (e.g. ketoconazole) and with caution in patients with pulmonary tuberculosis, thyrotoxicosis, pre-existing cardiovascular disease, patients predisposed to low levels of serum potassium and patients with diabetes mellitus.
