This real-life study aimed to assess omalizumab treatment patterns in adult and paediatric asthma patients, and to describe asthma control and healthcare resource use (HCRU) at omalizumab initiation and discontinuation. Methods The French healthcare database system (Système National des Données de Santé (SNDS)) was used to identify asthma patients aged ≥6 years who initiated omalizumab for at least 16 weeks from 2009 to 2019. We examined omalizumab treatment patterns using dispensation records. Results We identified 16 750 adults and 2453 children initiating omalizumab. Median treatment persistence before discontinuation (T STOP ) was 51.2 (95% CI 49.3–53.4) months in adults and 53.7 (95% CI 50.6–56.4) months in children. At 2 years of omalizumab exposure, rate of hospitalisation for asthma decreased by 75% and use of oral corticosteroids (OCS) by 30%, in adults and children. Among adults who discontinued omalizumab while asthma was controlled, 70%, 39% and 24% remained controlled and did not resume omalizumab at 1, 2 and 3 years after discontinuation, respectively. These proportions were higher in children (76%, 44% and 33%, respectively). Over 2 years of follow-up after discontinuation, HCRU remained stable in adults and children, notably rate of hospitalisations for asthma (none before T STOP , 1.3% and 0.6% at 2 years) and use of OCS (in adults and children, respectively: 20.0% and 20.2% before T STOP , 33.3% and 24.6% at 2 years). Conclusion This is the first large-scale study describing omalizumab real-life exposure patterns in adult and paediatric asthma patients in France with 〉 10 years of follow-up. We showed the long-term maintenance of low HCRU in adults and children who discontinued omalizumab while asthma was controlled, notably for OCS use and hospitalisations for asthma.
