Pocket guide: biologics in upper and lower airways in adults

The introduction of biologics for the treatment of severe upper and lower (type 2) airway inflammation has been a gamechanger in the management of these diseases. Biologics are injectable medications targeting different molecules relevant in (type 2) inflammation in patients with severe (type 2) airway diseases, like asthma, eosinophilic chronic obstructive pulmonary disease (COPD), chronic rhinosinusitis (CRS) and those who remain uncontrolled despite regular treatment (1-3). After the phase 3 trials, showing significant impact on symptoms, quality of life and interventions like surgery (for the upper airways) and exacerbations needing hospitalisation (for the lower airways), biologics are now used in daily practice in many parts of the world (4, 5). This pocket guide is aimed at all specialists treating adult patients with severe airway disease.
