Role of ICS in Asthma & COPD
Asthma is a heterogeneous disease, usually characterized by airflow inflammation.
It is defined by the presence of respiratory symptoms such as
• Wheezes.
• Shortness of breath.
• Cough .
• that vary overtime and in intensity, together with variable airflow limitation.
What is Asthma ? (GINA 2014)

Asthma: Burden
Asthma is a problem worldwide, with an estimated
300 million affected individuals
The global prevalence of asthma ranges from
1% to 18% of the population in different countries
The World Health Organization has estimated that asthma represents 1% of the total global disease burden
Annual worldwide deaths from asthma have been estimated at 250,000.

Severe allergic asthma
is a chronic condition,
which, when uncontrolled,
has a serious impact on
quality of life, morbidity,
mortality and health
expenditure
Asthma has serious consequences
~50,0000 hospitalisations each
year in Europe for people
with severe asthma2
40% of patients with asthma have
moderate-severe disease1
Inflammation causing:
1. Wheezing
2. Breathlessness
3. Chest tightness
4. Coughing
15,000 people die each year from
asthma attacks in Europe2
• Of 195 UK asthma-related
deaths 2012-13:
• 17% = allergic asthma3
• 39% = severe asthma3
$6,022 mean cost over 12 months
for a patient with
asthma that is uncontrolled
despite ICS+LABA5 Severe asthma accounts
for >50% of total costs despite being 5-10% of total asthma patients 6,7
~300 million people have
asthma worldwide4

Stepwise Approach for
Optimal Asthma
management
ICS in Asthma
ICS with or without LABA, continue to be the mainstay of pharmacological treatment for mild to moderate asthma.
Inhaled corticosteroids (ICS) are by far the most effective controllers used in the treatment of asthma.
The only drugs that can effectively suppress the characteristic inflammation in asthmatic airways, even in very low doses.
Pharmaceuticals 2010, 3, 514-540
ICS in Asthma (cont’d)
ICS are the recommended first-line therapy for persistent asthma of all severities and patients of all ages and are the most effective asthma medications currently available.
Pharmaceuticals 2010, 3, 514-540
Role of ICS in Asthma
ICS can reverse the specific chronic airway inflammation present in asthma.
ICS reduce the number of mast cells, macrophages, T-lymphocytes and Eosinophils in the sputum, broncho-alveolar lavage and bronchial wall.
ICS reverse the shedding of epithelial cells, goblet-cell hyperplasia and basement-membrane thickening characteristic of the airway mucosa of patients with asthma.

Cellular Effects
When taken regularly, inhaled corticosteroids:
• Effectively control everyday asthma symptoms.
• Improve lung function.
• Decrease the risk for exacerbations.
ICS in Asthma (cont’d)
Fernando D Martinez et al,Lancet 2013; 382: 1360–72
Controlled trials have consistently shown that inhaled corticosteroids are better than leukotriene receptor antagonists, such as montelukast, at :
• Controlling symptoms
• Improving lung function
• Reducing exacerbations
ICS in Asthma (cont’d)
Fernando D Martinez et al, Lancet 2013; 382: 1360–72
Several clinical trials have shown that patients who are still symptomatic after treatment with inhaled corticosteroids benefit from the addition of a LABA.
A larger proportion of such patients respond better to adding LABAs than to doubling the dose of inhaled corticosteroids or adding a leukotriene receptor antagonist.
Adding LABA is better than increasing ICS dose
Fernando D Martinez et al,Lancet 2013; 382: 1360–72
LABA with ICS for Asthma Management
ICS therapy in combination with long acting inhaled beta agonists (LABA) represents the most important treatment for asthma.
ICS therapy forms the basis for treatment of asthma of all severities, improving asthma control, lung function and preventing exacerbations of disease.
Eur J Clin Pharmacol (2009) 65:853–871
Anti-inflammatory Effects of β2-agonists in Asthma
β2-agonists not only cause bronchodilation, but also exert anti-
inflammatory effects as has been shown in many in vitro studies.
These effects include:
• Inhibition of the oxidative burst and release of thromboxane and leukotriene C4 from Eosinophils.
• Inhibition of mediator release from circulating neutrophils.
M van den Berge at al ,Clinical Medicine: Therapeutics 2009:1 77–93
LABA / ICS for Asthma Management
Adding a LABA is more effective than increasing the dose of ICS in terms of improving asthma control and reducing exacerbations.1
Use of inhaled corticosteroids plus Formoterol, a fast-onset LABA, has proven to be effective in preventing exacerbations.2
1- Pharmaceuticals 2010, 3, 514-540 2-Fernando D Martinez et al,Lancet 2013; 382: 1360–72
Interaction between β2-agonists and ICS
Corticosteroids can interact with β2-agonists in a beneficial way, since they prevent desensitization.
Effects of β2-receptors on Corticosteroids
β2-agonists are capable of potentiating the anti-inflammatory actions of corticosteroids.

ICS role in COPD
Recommendations for ICS are largely based on preventative effect on exacerbations
Use of ICS is associated with an 18% relative risk reduction in occurrence of exacerbations1
• The commonly cited MCID for change in exacerbation frequency is a 20% reduction2

Prediction
Diabetes risk may be increased with ICS use in patients with COPD
In an observational cohort study (n=388,584), the risk of diabetes associated with ICS use was investigated
In total, 30,167 patients had diabetes onset during the 5.5-year follow-up
The onset and progression of diabetes increased in patients with COPD receiving ICS1
• Increased risk of diabetes: RR 1.34 (95% CI 1.29, 1.39)
• Rate of diabetes progression: RR 1.34 (95% CI 1.17, 1.53)

Correct diagnosis is key
to deciding the treatment strategy,
which differs between asthma and COPD.
There are now good scientific reasons why even high doses of ICS fail to reduce inflammation in COPD patients.
This corticosteroid-resistance has been demonstrated by the failure of high doses of ICS to reduce inflammatory markers in sputum or bronchial biopsies of COPD patients.
Peter J. Barnes Respiration 2010;80:89–95
Possible reasons for corticosteroid resistance
The reason for the extreme corticosteroid resistance in COPD may be due to a marked reduction in the nuclear enzyme histone deacetylase-2 (HDAC2), which is required for corticosteroids to switch off activated inflammatory genes that are associated with histone acetylation
Peter J. Barnes Respiration 2010;80:89–95
Possible mechanisms for decreased HDAC-2 activity in smokers with asthma and COPD.
Respiratory Medicine (2012) 106, 319-328
Inactivation of HDAC-2 results in increased inflammatory gene
expression and reduced response to anti-inflammatory actions of corticosteroids.
Glucocorticoids have been reported not to reduce, but even to increase, neutrophils numbers in induced sputum
Corticosteroids inhibit neutrophils apoptosis at clinically relevant drug concentrations and the effect seems to be mediated through glucocorticoid receptors.
Accordingly, oral and inhaled corticosteroids have been reported to increase neutrophils numbers in the lung tissue.

Inhaled corticosteroids in COPD: the clinical evidence:Pierre Ernst, Nathalie Saad, Samy Suissa ERS J Published 1 February 2015
In this article, we focus on the scientific evidence from
randomised trials supporting treatment with inhaled
corticosteroids (ICS) in chronic obstructive pulmonary
disease (COPD), including treatment with combinations of
long-acting β-agonist (LABA) bronchodilators and ICS. Our
emphasis is on the methodological strengths and limitations
that guide the conclusions that may be drawn.
Inhaled corticosteroids in COPD: the clinical evidence:Pierre Ernst, Nathalie Saad, Samy Suissa ERS J Published 1 February 2015
The evidence of benefit of ICS and, therefore, of the
LABA/ICS combinations in COPD is limited by major
methodological problems. From the data reviewed herein,
we conclude that there is no survival benefit independent of
the effect of long-acting bronchodilation and no effect on
FEV1 decline, and that the possible benefit on reducing
severe exacerbations is unclear. Our interpretation of the
data is that there are substantial adverse effects from the
use of ICS in patients with COPD, most notably severe
pneumonia resulting in excess deaths.
Inhaled corticosteroids in COPD: the clinical evidence: Pierre Ernst, Nathalie Saad, Samy Suissa ERS J Published 1 February 2015
Currently, the most reliable predictor of response to ICS in
COPD is the presence of eosinophilic inflammation in the
sputum. There is an urgent need for better markers of
benefit and risk that can be tested in randomised trials for
use in routine specialist practice. Given the overall safety
and effectiveness of long-acting bronchodilators in subjects
without an asthma component to their COPD, we believe
use of such agents without an associated ICS should be
favoured.

* In a post-hoc analysis
Where does dual bronchodilation fit?
For patients in GOLD Groups B, C, and D, a LABA/LAMA combination is included as an alternative choice option1
Which patients will benefit from dual bronchodilation?
The IGNITE Phase III clinical program showed superior efficacy on a variety of outcomes (including lung function, dyspnea, health status) to placebo and active comparators in patients in Groups A, B, and D2–7
• In particular, ILLUMINATE highlighted the potential of LAMA/LABA therapy to replace and provide superior efficacy to ICS/LABA in GOLD Group B patients2

Importance of Dual Bronchodilation
In Conclusion.....
When should physicians consider stepping up or switching to dual bronchodilation?
Physicians recognize symptomatic patients who require treatment change and also for ‘not well controlled’ and ‘symptomatic’ patients8
The GOLD 2013 strategy advocates more focus on symptoms that may improve patient outcomes, if adhered to1
Importance of Dual Bronchodilation
In Conclusion.....
Summary
ICS use is associated with benefits in lung function, HRQoL and exacerbation risk
However, ICS use was found to be associated with increased risk pneumonia, bone fracture and diabetes
Real-world prescription data indicate that ICS are prescribed to patients with all severities of COPD, contrary to GOLD recommendations
Withdrawal of ICS may be warranted and appropriate in some patients
• Studies have shown no increased risk of moderate-to-severe exacerbations following ICS withdrawal in patients with moderate COPD and no exacerbation history if
appropriate bronchodilator therapy is in place
COPD = chronic obstructive pulmonary disease GOLD = Global initiative for chronic Obstructive Lung Disease HRQoL = health-related quality of life ICS = inhaled corticosteroid
Dual bronchodilation : summary
The GOLD 2015 strategy document recommends combining bronchodilators in Groups B−D in order to optimize symptom benefits
β2-agonists and muscarinic antagonists target different sites and modes of action
Several studies have shown that LAMA/LABA free combinations provide greater bronchodilation than LAMA or LABA monotherapy, which translated in greater improvements in important clinical outcomes
QVA149 is an inhaled fixed-dose combination indacaterol and glycopyrronium approved for the treatment of COPD
COPD = chronic obstructive pulmonary disease
LABA = long-acting β2-agonist; LAMA = long-acting muscarinic antagonist
