© 2026 Elsevier Ltd. Background: Severe asthma affects a minority of patients with asthma; however, it substantially impacts morbidity, health-care use, and systemic corticosteroid-related harm. Despite the increasing use of biological treatments, achievement of severe asthma remission remains elusive. Notably, real-world data on the disease burden and remission potential of severe asthma in Europe remain limited. We aimed to close this knowledge gap, offering insights with global relevance. Methods: Using data from 13 455 adults with severe asthma enrolled in the European Severe Heterogeneous Asthma Registry, Patient-centred Clinical Research Collaboration (SHARP CRC), this cross-sectional observational study evaluated the burden of severe asthma and remission-related clinical domains (exacerbations, asthma control, airflow limitation, and maintenance oral corticosteroid use) across Europe and examined their relationship with disease duration, biological therapy, and type 2 biomarkers (blood eosinophils, fractional exhaled nitric oxide [FeNO], and total IgE). Patients with severe asthma had been enrolled in national registries according to local principles and guidelines and in accordance with the European Respiratory Society/American Thoracic Society guidelines; 3% (430 of 13 885) of patients were excluded due to no consent for the international study and/or missing medication data. Findings: Patients were predominantly female (59%; 7999 of 13 453), with adult-onset asthma (82%; 8751 of 10 711), and a median disease duration of 23 years (95% CI 20–26 years). 59% (4148 of 7006) of patients had FEV1/FVC of 0·7 or less, 62% (4680 of 7568) had FEV1 lower than 80% predicted, and 89% (3519 of 3968) had at least one active disease domain. Despite 79% (10 632 of 13 453) receiving biological therapy, more than 66% (2621 of 3968) still had at least two active domains. Elevation of type 2 biomarkers persisted (89% [2806 of 3153] with at least one elevated biomarker) despite widespread biological and maintenance oral corticosteroid treatment. A subset of biologic-naive patients (35%; 1069 of 3018) exhibited a rapid accumulation of disease burden within less than 10 years, suggesting a potentially accelerated progression trajectory. Interpretation: This pan-European analysis of severe asthma revealed significant clinical heterogeneity and a substantial disease burden despite advanced therapies, highlighting the enduring nature of type 2 inflammation, the potential inadequacy of current remission strategies with available therapeutic approaches, and the necessity for early identification of high-risk patients.
