In patients with severe asthma not controlled with GINA step 4-5 and National Asthma Education and Prevention Program (NAEPP) step 5 combination therapies, the addition of the long-acting muscarinic agent tiotropium has been shown to reduce as-needed use of SABAs, improve forced expiratory volume in 1 second (FEV1), and moderately reduce the risk for a severe exacerbation.

ERS/ATS guidelines conditionally recommend a trial of macrolide therapy in adult patients on GINA/NAEPP step 5 therapy who remain persistently symptomatic or uncontrolled to reduce asthma exacerbations.

According to the ERS/ATS guidelines, a blood eosinophil level of ≥ 260/μL and FeNO ≥ 20 ppb are important considerations that may help predict a good response to anti-IgE treatment in patients with severe asthma.

In randomized controlled trials, monoclonal antibodies that target IL-5 (eg, mepolizumab, reslizumab) or its receptor IL-5Rα (eg, benralizumab) have been shown to improve asthma-related outcomes. Anti-IL-5 and anti-IL-5Rα therapies reduce exacerbations and hospitalizations in patients with severe eosinophilic asthma. Mepolizumab and benralizumab are effective in reducing maintenance oral corticosteroid dose in patients with corticosteroid-dependent severe asthma. Another monoclonal antibody or biological agent, dupilumab, has also been shown to inhibit the biological effects of IL-4 and IL-13, thereby reducing chronic airway inflammation, tissue remodeling, and bronchial hyperresponsiveness.
