IL-4, IL-5, AND IL-13 ARE

IL-5 promotes activation,
survival, and recruitment of

IL-13 causes goblet cell hyperplasia and drives increased mucus secretion9

Key cytokines driving type 2 inflammation

Adapted from Hammad H et al, 2008.

Production of downstream
cytokines, including
IL-5, IL-9, and IL-134

Th2 cell differentiation, mast cell recruitment, and class switching in B cells to produce IgE4

Recruitment of eosinophils5-8

~71% of severe asthma patientsa not treated with an
anti-IgE biologic were ineligible for available
biologics,b highlighting the unmet medical need1

  • a N=502; Australia, USA, Canada eligibility criteria (65%);
    France, Germany, UK eligibility criteria (76%).
  • b As of October 2017.

Elevated periostin levels are often associated with Type 2 inflammation2

yellow cloud icon


Elevated FeNO levels are often associated with Type 2 inflammation2

c Exacerbations were 3 times more likely to occur in patients with uncontrolled asthma than in those with better asthma control3

  • Patients miss out on outdoor, physical, and other daily activities4
  • Anxiety and depression worsen symptoms and complicate disease management5

Patients with a history of exacerbations had about twice the yearly decline in FEV1 over 3 years than those without exacerbations6
