Optimal asthma control goes beyond exacerbation reduction

Patients with uncontrolled persistent asthma may experience impacts on their lungs and quality of life2-7

lung function8-11
Potential side
effects with OCS use7,12-14
Poor quality
of life5,6

Impaired lung function contributes to risk of future severe
exacerbations and poor asthma control2,15

Lung function is critical to the assessment of future risk in patients with asthma13

  • 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 exacerbations16
  • Early and sustained improvements in lung function following therapy initiation reduced the rate and severity of future exacerbations3
There remains an unmet need to provide comprehensive care for
patients with uncontrolled persistent asthma2,13,17,18

GINA recommends considering the presence of Type 2 inflammation in patients
with severe asthma who are taking high-dose ICS or daily OCS by identifying any
one of the below13,a,b:

Blood EOS
≥150 cells/µL
sputum EOS ≥2%


≥20 ppb


Clinically allergen-
driven asthma


OCS dependence

Consider coexisting Type 2 inflammatory diseases

Biologic add-on therapy may be a viable option for treating
certain asthma patients with Type 2 inflammation13

a The below are not the criteria for eligibility for Type 2–targeted biologic therapy.
b Patients dependent on OCS may also have underlying Type 2 inflammation; however, biomarkers of Type 2 inflammation are often suppressed by OCS. If possible, therefore, these tests should be performed before starting OCS or on the lowest possible OCS dose.

CRSwNP, chronic rhinosinusitis with nasal polyposis; EOS, eosinophils; FeNO, fractional exhaled nitric oxide; FEV1, forced expiratory volume in 1 second; ICS, inhaled corticosteroid; OCS, oral corticosteroid.
