Optimal Asthma Control
Goes Beyond Exacerbation Reduction


Patients with uncontrolled persistent asthma may experience
higher exacerbation rates, impaired lung function, risk of long-term
OCS side effects, and poor quality of life1-6

High exacerbation rates
High exacerbation rates
  • Exacerbations were 3 times more likely to occur
    in patients with uncontrolled asthma rates than in those
    with better asthma control1
Impaired lung function
Impaired lung function
  • Reversible airway obstruction in uncontrolled asthma is caused by bronchoconstriction and mucus production7-10
  • Airway remodeling, often driven by persistent Type 2 inflammation, can lead to impaired lung function in both the large and small airways7-10
Potential side effects with OCS
Potential side effects with OCS
  • Due to the potential for substantial side effects
    with OCS use, guidelines suggest not using OCS as
    maintenance therapy until all other pharmacologic
    options have been exhausted11,12
  • Long-term use of OCS has been associated with
    osteoporosis, arterial hypertension, diabetes and
    metabolic syndrome, dyslipidemia, obesity,
    cataracts, glaucoma, gastrointestinal bleeds/ulcers,
    tuberculosis, depression, herpes, and sepsis6,13
Poor QoL
Poor QoL
  • Patients miss out on outdoor, physical, and other
    daily activities4
  • Anxiety and depression worsen symptoms
    and complicate disease management5

Impaired lung function contributes to risk of future severe
exacerbations and poor asthma control1,14

Lung function is critical to the assessment of future risk in patients with asthma12

  • Patients with frequent exacerbations and moderate-to-severe asthma experienced
    a significantly greater annual decline in FEV1 in a long-term study, compared with patients
    who had infrequent exacerbations15
  • Early and sustained improvements in lung function following therapy initiation reduced
    the rate and severity of future exacerbations16

Lung function should be measured as part of the assessment of asthma control12:

  • At the start of treatment
  • After 3 to 6 months of treatment
  • Periodically thereafter for ongoing risk assessment
There remains an unmet need to provide
comprehensive care for patients with
uncontrolled persistent asthma

FEV1, forced expiratory volume in 1 second; OCS, oral corticosteroids; QoL, quality of life.
