COVID-19 and asthma (as at April 3,
2020)
• Advise patients with asthma to continue taking their prescribed asthma medications, particularly inhaled
corticosteroids (ICS), and oral corticosteroids (OCS) if prescribed
– Asthma medications should be continued as usual. Stopping ICS often leads to potentially dangerous
worsening of asthma
– For patients with severe asthma: continue biologic therapy, and do not suddenly stop OCS if
prescribed
• Make sure that all patients have a written asthma action plan with instructions about:
– Increasing controller and reliever medication when asthma worsens
– Taking a short course of OCS for severe asthma exacerbations
– When to seek medical help
– See the GINA 2020 report for more information about treatment options for asthma action plans.
• Avoid nebulizers where possible
– Nebulizers increase the risk of disseminating virus to other patients AND to health care professionals
– Pressurized metered dose inhaler via a spacer is the preferred treatment during severe
exacerbations, with a mouthpiece or tightly fitting face mask if required

COVID-19 and asthma (as at
March 30, 2020)
• Avoid spirometry in patients with confirmed/suspected COVID-19
– Spirometry can disseminate viral particles and expose staff and patients to risk of infection
– While community transmission of the virus is occurring in your region, postpone spirometry and
peak flow measurement within health care facilities unless there is an urgent need
– Follow contact and droplet precautions
• Follow strict infection control procedures if aerosol-generating procedures are needed
– For example: nebulization, oxygen therapy (including with nasal prongs), sputum induction, manual
ventilation, non-invasive ventilation and intubation
– World Health Organization (WHO) infection control recommendations are found here:
www.who.int/publications-detail/infection-prevention-and-control-during-health-care-when-novel-
coronavirus-(ncov)-infection-is-suspected-20200125
• Follow local health advice about hygiene strategies and use of personal protective equipment, as new
information becomes available in your country or region

About the GINA strategy
• The GINA report is not a guideline, but an integrated evidence-based strategy
focusing on translation into clinical practice
• Recommendations are framed, not as answers to isolated PICOT questions, but
as part of an integrated strategy, in relation to:
– The GINA goals of preventing asthma deaths and exacerbations, as
well as
improving symptom control
– Current understanding of underlying disease processes
– Human behaviour (of health professionals and patients/carers)
– Implementation in clinical practice
– Global variation in populations, health systems and medication access

A reminder – the key change in GINA 2019

Background to changes in 2019 - the risks of
‘mild’ asthma
• Patients with apparently mild asthma are at risk of serious adverse events
– 30–37% of adults with acute asthma
– 16% of patients with near-fatal asthma
– 15–20% of adults dying of asthma
• Exacerbation triggers are variable (viruses, pollens, pollution, poor adherence)
• Inhaled SABA has been first-line treatment for asthma for 50 years
– This dates from an era when asthma was thought to be a disease of
bronchoconstriction
– Patient satisfaction with, and reliance on, SABA treatment is reinforced by
its rapid relief of symptoms, its prominence in ED and hospital
management of exacerbations, and low cost
– Patients commonly believe that “My reliever gives me control over my
asthma”, so they often don’t see the need for additional treatment
had symptoms less than weekly in
previous 3 months (Dusser, Allergy
2007)

Background to changes in 2019 - the risks of SABA-only treatment
• Regular or frequent use of SABA is associated with adverse effects
– b-receptor downregulation, decreased bronchoprotection, rebound
hyperresponsiveness, decreased bronchodilator response (Hancox, Respir Med
2000)
– Increased allergic response, and increased eosinophilic airway inflammation
(Aldridge, AJRCCM 2000)
• Higher use of SABA is associated with adverse clinical outcomes
– Dispensing of ≥3 canisters per year (average 1.7 puffs/day) is associated with
higher risk of emergency department presentations (Stanford, AAAI 2012)
– Dispensing of ≥12 canisters per year is associated with higher risk of death (Suissa,
AJRCCM 1994)

The 12-year history behind changes in GINA 2019
• Since 2007, GINA has been actively seeking interventions for mild asthma
– to reduce the risk of asthma-related exacerbations and death
– to provide consistent messaging about the goals of asthma treatment, including
prevention of exacerbations, across the spectrum of asthma severity
– to avoid establishing patient reliance on SABA early in the course of the disease
• GINA emphasized poor adherence as a modifiable risk factor for exacerbations
– When the reliever is SABA, poor adherence with maintenance controller exposes
the patient to risks of SABA-only treatment
• GINA members repeatedly sought funding for RCTs of as-needed ICS-formoterol
for risk reduction in mild asthma
– Eventually culminated in 2014 with the initiation of the SYGMA studies, published
in 2018
(O’Byrne NEJMed 2018; Bateman NEJMed 2018)

GINA 2019 – landmark changes in asthma management
• For safety, GINA no longer recommends SABA-only treatment for Step 1
– This decision was based on evidence that SABA-only treatment increases
the risk of severe exacerbations, and that adding any ICS significantly
reduces the risk
• GINA now recommends that all adults and adolescents with asthma should receive
ICS-containing controller treatment, to reduce the risk of serious exacerbations
– The ICS can be delivered by regular daily treatment or, in mild asthma,
by as-needed low dose ICS-formoterol
• This is a population-level risk reduction strategy
– Other examples: statins, anti-hypertensives
– Individual patients may not necessarily experience (or be aware of) short-
term clinical benefit
– The aim is to reduce the probability of serious adverse outcomes at a
population level

The main GINA treatment figure
• Personalized asthma management: Assess – Adjust – Review response
– NOT just medications, NOT one-size-fits-all
• No changes from 2019 in preferred and ‘other’ treatment options
– Additional supporting evidence for recommendations in Steps 1 and 2
– Some formatting changes for clarity
• Separate figures for adults/adolescents, children 6–11 years and children ≤5 years
– For children ≤5 years, see Chapter 6 of main GINA report

ICS-formoterol is
the preferred
reliever for patients
prescribed
maintenance and
reliever therapy. For
other
ICS-LABAs, the
reliever
is SABA
GINA 2020, Box 3-5A

Additional supporting evidence
• Two additional RCTs of as-needed low dose budesonide-formoterol in mild asthma
– 12-month studies, open-label, no twice-daily placebo, i.e. the way it would be used in
real life
– Novel START (Beasley et al, NEJM 2019, n=668) and PRACTICAL (Hardy et al,
Lancet 2019,
independent study, n=885)
– Significant reduction in severe exacerbations vs SABA alone, and vs maintenance
ICS, with small or no difference in symptom control, and lower average ICS dose
– Patients in RCTs of this regimen in mild asthma now total n=9,565
• Both of these studies included inflammatory markers
– FeNO was significantly reduced by as-needed ICS-formoterol (with average 3-5 doses
per week)
– Reduction in risk of severe exacerbations with as-needed ICS-formoterol was
independent of baseline characteristics, including blood eosinophils and exhaled
nitric oxide
• An additional RCT of taking ICS whenever SABA is taken (separate inhalers)
– ASIST, in African-American children 6-17 years with mild asthma, compared with
physician-adjusted treatment (Sumino et al, JACI in Pract 2019, n=206)

Initial asthma treatment – where to start?

As-needed ICS-formoterol – maximum daily dose?
• As-needed low dose budesonide-formoterol
– Prescribed in maintenance and reliever therapy (Steps 3–5), or as-needed
only (Steps 1–2),
or within an asthma action plan
– From product information, the maximum recommended total in one day is
72 mcg formoterol
(12 inhalations of budesonide-formoterol Turbuhaler 200/6 mcg)
• As-needed low dose beclometasone-formoterol
– Prescribed in maintenance and reliever therapy (Steps 3–5), or within an
asthma action plan
– From product information, the maximum recommended total in one day is
48 mcg formoterol
(6 inhalations of beclometasone-formoterol pMDI100/6 mcg)

Assessment of symptom control
• Frequency of SABA use is included in symptom control assessment
– Higher SABA use is associated with worse outcomes, even in
patients taking ICS
Our current view is that frequency of ICS-formoterol use should not be included in symptom
control assessment, particularly in patients not taking maintenance ICS
– The as-needed ICS-formoterol is providing the patient’s controller therapy
– Further data awaited: this issue will be reviewed again next year

Low, medium and high doses of different ICS
• NOT a table of equivalence
– Suggested total daily doses for ‘low’, ‘medium’ and ‘high’ dose treatment
options
– Based on available studies (very few) and product information
– Does NOT imply potency equivalence
• Doses may be country-specific depending on local availability, regulatory labelling
and clinical guidelines
• Clinical relevance
– Low dose ICS provides most of the clinical benefit of ICS for most patients
with asthma
– However, ICS responsiveness varies between patients, so some patients
may need medium dose ICS if their asthma is uncontrolled despite good
adherence and correct technique
– High dose ICS (in combination with LABA or separately) is needed by
very few patients
• Its long-term use is associated with an increased risk of local and systemic
side-effects, which must be balanced against the potential benefits

Low, medium and high ICS doses: adults/adolescents
GINA 2020, Box 3-6A
DPI: dry powder inhaler; HFA: hydrofluoroalkane propellant; pMDI: pressurized metered dose inhaler (non-CFC); * see product
information
These are suggested total daily doses for the ‘low’, ‘medium’
and ‘high’ dose treatment options with different ICS.

Low, medium and high ICS doses: children 6-11 years
GINA 2020, Box 3-6B
DPI: dry powder inhaler; HFA: hydrofluoroalkane propellant; pMDI: pressurized metered dose inhaler (non-CFC); * see product information
This is NOT a table of equivalence. These are suggested total
daily doses for the ‘low’, ‘medium’ and ‘high’ dose treatment
options with different ICS.

Low, medium and high ICS doses: children 5 years and
younger
GINA 2020, Box 3-6B
BDP: beclometasone dipropionate; DPI: dry powder inhaler; HFA: hydrofluoroalkane propellant; pMDI: pressurized metered dose
inhaler (non-CFC)
This is NOT a table of equivalence. These are suggested total
daily doses for the
‘low’ dose treatment options with different ICS.

Adverse effects with montelukast
• FDA boxed warning in March 2020 about risk of serious
neuropsychiatric events, including suicidality, with
montelukast
– Includes suicidality in adults and adolescents
– Nightmares and behavioural problems in children
• Before prescribing montelukast, health professionals should
consider its benefits and risks, and patients should be
counselled about the risk of neuropsychiatric events

Asthma management in children
• School-based programs that included asthma self-management are associated with
improved asthma outcomes (Kneale et al, Thorax 2019)
– Fewer emergency department visits
– Fewer hospitalizations
– Fewer days of reduced activity
• Severe eosinophilic asthma in children aged 6-11 years
– Mepolizumab approved by European Medicines Agency for this age-group
(already approved for 12 years and older)
– Efficacy data are limited to one small uncontrolled open-label study
(Gupta et al, JACI 2019)
• Children aged 5 years and younger
– Assessment of severe exacerbations updated: respiratory rate >40/min
added; pulse rate criteria modified; sub-glottic/sub-sternal retractions
removed as too subjective

Difficult-to-treat and severe asthma
• Pocket guide v2.0 published April 2019
– A practical guide for primary and specialist care
– Includes a decision tree about assessment and management of
adults and adolescents with uncontrolled asthma or
exacerbations despite Step 4-5 treatment
– Includes strategies for clinical settings in which biologic
therapy is not available or affordable
• Content also included in full GINA 2020 report
• Aim is to produce a similar pocket guide for children in 2020

Patients with features of asthma and COPD
• Also called ‘asthma-COPD overlap’ or ‘asthma+COPD’
– NOT a single disease, but a descriptive label for patients commonly seen in clinical practice
• Asthma and COPD are heterogeneous and overlapping conditions
– The definitions of asthma and COPD are not mutually exclusive
– Each includes several phenotypes that are likely to have different underlying mechanisms
– There is increasing interest in the potential for precision treatment
• However, the labels ‘asthma’ and ‘COPD’ are still clinically important, as evidence supports safety-based
differences in treatment recommendations
– Asthma: never treat with bronchodilators alone (risk of death, hospitalization, severe
exacerbations)
– COPD: start treatment with LABA and/or LAMA without ICS
– Patients with diagnoses of both asthma and COPD are more likely to die or be hospitalized if
treated with LABA vs ICS-LABA (Gershon et al, JAMA 2014; Kendzerska et al, Annals ATS 2019)
– High dose ICS may be needed for severe asthma, but should not be used in COPD (risk of
pneumonia)

Patients with features of asthma and COPD
GINA 2020, Box 5-2

Other changes in GINA 2020
• Acute asthma
– References to ‘high flow oxygen’ have been corrected to ‘high concentration
oxygen’
• Role of trained lay health workers in asthma education has been emphasized
– Improved outcomes compared with usual care including increased symptom-free
days, reduced healthcare utilization, improved adherence, inhaler technique,
symptom control and quality of life
• Factors contributing to development of asthma
– Obesity may be a risk factor for developing asthma (Deng et al, Pediatr Obes
2019),
but not vice versa (Xu et al, Int J Epidemiol 2019)
– 13% of global asthma incidence in children may be attributable to traffic-related
air pollution (Achakulwisut et al, Lancet Plan Health 2019)

GINA methodology – additional details
• The GINA report is a global strategy document
– Regulatory approvals and submissions differ from country to country
– Many recommendations are ‘off-label’ in various countries, particularly for
paediatrics
 The term ‘off-label’ is no longer used in the GINA report or slides
• For new therapies
– Regulatory agencies often receive more safety data than are in peer-reviewed
literature
 GINA makes recommendations based on the best available evidence, after
approval by at least one major regulatory agency (e.g. EMA, FDA)
• For existing medications with evidence for new regimens or populations
– If satisfied with evidence for safety and effectiveness, GINA may consider
making recommendations that are not covered by a regulatory indication in any
country at the time
– Examples: long-term macrolides for moderate-severe asthma (2018); as-needed
ICS-formoterol, or taking ICS whenever SABA is taken, for mild asthma (2019)
• When assessing and treating patients
– Use your own professional judgment
– Take into account local and national guidelines and payer eligibility criteria, and
licensed drug doses
