COPD is a progressive
disease with inflammation
as a key process
Understanding inflammation
• Airway inflammation negatively affects health
status of COPD patients1
• Higher levels of certain inflammatory markers are
associated with a decline in lung function and
subsequent disease progression2
1. Snoeck-Stroband JB et al. Respir Res 2006; 7: 140. 2. Parr DG et al. Respir Research 2006; 7: 136 (online journal).
Inflammation is present even in the
early stages of COPD
• Airway inflammation is characterised by increased
numbers of neutrophils, macrophages and CD8+
lymphocytes1,2
• Infiltration of inflammatory cells into the airways occurs in
both early and late stages of COPD3
• As the disease progresses, the small airways fill with
inflammatory mucus exudates3
• The presence of inflammation in the airways provides a
rationale for using inhaled corticosteroids and long-acting
beta2-agonists to treat the disease

The Anti-inflammatory Effect Is
Associated With A Reduced Rate In
The FEV1 Decline
Ann Intern Med. 2009;151:517-527.
Synergistic effects of SFC
• Bourbeau et al suggest that combination therapy has anti-inflammatory
effects, not seen with inhaled corticosteroids alone1
• Compared with monotherapy, enhanced effects for combination are
consistent not only with clinical data but also with in vitro data2–5
• Bourbeau et al propose that the anti-inflammatory activity seen with SFC
but not FP may be due to additive or synergistic effects at the receptor
level1
• Corticosteroids may regulate 2 receptor function by increasing
expression of the receptor, and inhibiting 2 receptor down-regulation6,7

COPD 2013
• “patients who benefit the most from inhaled
bronchodilators seem to be those who have respiratory
symptoms and airflow obstruction with an FEV1 less than
60% predicted”
• “monotherapy using either long acting inhaled
anticholinergics or long acting beta agonists(but not
inhaled steroids as monotherapy) for symptomatic
patients with an FEV1 of less than 60% predicted is
recommended

Summary of data of different therapeutic
studied in patients with COPD
• UPLIFT (Tiotropium achieves improvement in lung
function over time, although rate of decline not reduced;
reduction in frequency of exacerbations and in
hospitalizations; no difference in mortality between
tiotropium and placebo
• TORCH- reduction in the rate of decline in airflow
limitation in the salmeterol/fluticasone arm compared to
placebo
• INSPIRE – comparison of SFC versus tiotropium in
severe COPD – no difference in exacerbation frequency
between the two treatments. Question of better quality of
life and reduced mortality risk with SFC.
Summary of data of different therapeutic
studied in patients with COPD
• Tiotropium/formoterol (Foradil) vs salmeterol(Serevent)/fluticasone in
moderate COPD – TF superior in lung function over the day
compared to SF (this study appeals to me, Chest 2008;134:255)
• OPTIMAL (Tiotopium/placebo, T plus salmeterol, T plus
salmeterol/fluticasone) – patients treated with T/F/S had significantly
better disease specific quality of life and fewer hospitalizations
compared to T/placebo, however these improvements in health
outcomes were associated with increased costs. Monotherapy with T
most economically attractive. Exacerbation rate did not differ
Others therapy
• Immunizations – both Pneumovax and influenza (this is an
“accepted” recommendation)
• Testing for alpha-one-anti-trypsin deficiency –
• Lung volume reduction surgery (or “medical treatment utilizing
valves”) - not a common procedure, but may be considered in very
symptomatic patients with well documented predominant upper lobe
emphysema with an FEV1 and DlCO of more than 20% of predicted
• Transplantation - LVRS may be a bridge to this. When to refer –
BODE index of over 5, post dilator FEV1 of less than 20% predicted,
resting hypoxemia, hypercapnia, secondary PH, accelerated decline
in FEV1 – but…is there a survival benefit?

COPD 2013
• Roflumilast – this is a PDE-4 inhibitor (PDE-4
inhibition decreases inflammation and promotes
airway smooth muscle relaxation)
• Approved for COPD patients with a history of
exacerbations – the experience is limited, but this agent
may be useful perhaps not only in COPD, but in asthma,
bronchiectasis, etc – time will tell
• Mucoactive agents- the jury is out, but some
patients may improve, some even think that they
are better than the inhaled medications (but this
is doubtful)

PA:A ratio of more than 1 at baseline was
associated with future exacerbations of COPD,
particularly those requiring hospitalization
The PA:A ratio also appears to outperform many established risk factors for
exacerbation including GERD, SGRQ score, breathlessness, chronic bronchitis,
and FEV1,as well as recently identified CT predictors.

In patients presenting to the ER with acute
exacerbation, 5-day treatment of prednisone (40mg
daily) was noninferior to 14-day treatment
• Non inferiority was defined as a 15% absolute difference

Conclusions
The burden of COPD is high and is rising1
• COPD is a multicomponent disease with inflammation at
its core2
•
• It is important to treat the underlying inflammation, which
is present even in the early stages of the disease3,4
• Patients on SFC have significantly improved lung
function and quality of life, and a significant reduction in
exacerbations compared with components or placebo5

Conclusions
• Exacerbations are common. Patients with previous
exacerbations are more likely to have more. Presence of
cough and sputum production are associated with more
exacerbations
• Antibiotics are useful to treat exacerbations in patients
with mild to moderate COPD
• Prednisone 40 mg daily for 5 days is enough
• Use of β-blockers in patients with HF, even non selective
are well tolerated and may be associated with improve
survival

Rationale for combining long-acting

•
Inhaled bronchodilators are the foundation
of COPD treatment
•
Most patients with COPD improve with
bronchodilation
•
Maximal bronchodilation is not achieved
using clinically approved doses of 1 class of
bronchodilator alone
•
There could be synergistic interactions

Astra Zeneca – PATHOS Study
• Objectives:
– To investigate exacerbation rates in primary care patients with COPD
treated with BF vs FS.
• Methods:
– Data from primary care medical records.
– Pairwise (1:1) propensity score matching.
• Results
– Matching of 9893 patients (7155 BF; 2738 FS yielded two cohorts of
2734 patients), comprising 19,170 patient-years.
– The exacerbation rates were 0.80 and 1.09 per patient-year BF and FS
– Yearly rates for COPD-related hospitalizations were 0.15 and 0.21,
respectively
• Conclusions
– Long-term treatment with fixed-combination BF was associated with
fewer exacerbations than FS in patients with moderate and severe
COPD.

Inhibition of release of
inflammatory mediators by p38 inhibitors
- Signalling through p38 mitogen-activated protein kinase (p38MAPK) is required for the expression of a range of inflammatory
mediators associated with COPD such as tumor necrosis factor α,
interleukin-1 (IL-1), IL-6 and IL-8.
- PH-797804 is a potent, selective p38-MAPK
