Recent Advances and New Therapeutic Goals in the Management of Severe Asthma.

Asthma is characterized by chronic airway inflammation as its primary pathological condition, which leads to various respiratory symptoms due to airway narrowing, with type 2 inflammation playing a central role. Asthma treatment, primarily centered on inhaled corticosteroids, aims to suppress type 2 inflammation and improve airway narrowing. However, severe asthma that cannot be controlled with high-dose inhaled corticosteroids or other asthma medications remains a clinical issue. The availability of multiple biological agents has recently improved the management of severe asthma. In addition, the concept of clinical remission has emerged as a treatment goal, further clarifying the objectives of asthma management. However, despite these advancements, the treatment of severe asthma driven primarily by non-type 2 inflammation remains a major challenge, and new biologics are currently being developed to address this issue.
