Background: Some patients with severe asthma have overlapping allergic and eosinophilic phenotypes and may be eligible for anti-eosinophilic or anti-IgE biologics.
Objective: This post hoc sub-analysis assessed real-world mepolizumab effectiveness in patients with overlapping allergic and eosinophilic phenotypes, using 1-year data from the international, prospective REALITI-A study.
Methods: The clinically significant asthma exacerbation (CSE) rate was assessed 1 year prior to (pre-treatment) and following (follow-up) mepolizumab treatment, stratified by baseline total IgE levels (tIgE; <60, 60-<190, 190-<550, and ≥550 kU/L), atopic status (yes/no/unknown), prior omalizumab use (yes/no), geographic baseline omalizumab eligibility (eligible/non-eligible), and baseline tIgE level and blood eosinophil count (BEC) threshold combinations (<81 or ≥81 kU/L and <300 or ≥300 cells/µL).

Anti-interleukin-5 (IL-5), anti-IL-5 receptor and anti-interleukin-4 (IL-4) have emerged as potential treatments for severe eosinophilic asthma, yet their role in treating chronic obstructive pulmonary disease (COPD) is unclear. A literature review was conducted up to May 31, 2024. Only randomized controlled trials (RCTs) assessing the clinical efficacy and adverse effects of biological treatment (anti-IL-5/ anti-IL-5 receptor /anti-IL-4) in COPD patients were included in this meta-analysis.

Background: COPD remains a leading cause of morbidity and mortality worldwide. Acute exacerbations are associated with progressive decline in lung function and quality of life. After recognition of the role of type 2 inflammation in the pathogenesis of eosinophilic COPD, there was increased interest in studying monoclonal antibodies as a therapeutic agent.

Chronic obstructive pulmonary disease (COPD) is a main global epidemic increasing as population age and affecting approximately 10% of subjects over 45 years. COPD is a heterogeneous inflammatory disease with several endo-phenotypes and clinical presentations. Although neutrophilic inflammation is canonically considered a hallmark of COPD, eosinophilic inflammation can also be present in a subgroup of patients.
