Real-life omalizumab exposure and discontinuation in a large nationwide population-based study of paediatric and adult asthma patients.

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.
