Open Label, Observational Study for Children & Adolescent With Severe Asthma With an Eosinophilic Phenotype Treated With Mepolizumab

• Status: Not yet recruiting
• Trial end date: 2024-12-01
• Target enrollment: 0
• Participant gender: All

Summary

Open label, observational cohort study conducted to collect demographics, clinical characteristics and outcome observational data from children (6-17 years) with a clinical diagnosis of severe asthma in 2 countries (Spain and United Kingdom), in public institutions.

All eligible participants who have a physician decision to initiate mepolizumab treatment and are consented for the study will be observed.

Subjects must have received mepolizumab (Nucala) since authorisation by EMEA in September 2018 (in Spain since December 2019) as an add-on treatment for severe refractory eosinophilic asthma in paediatric patients aged six up to 17 years. The study will be implemented in 16 investigating sites (10 in Spain and 6 in UK). The assignment of a patient to a particular therapeutic strategy is not decided in advance by the study protocol, but is determined by the usual practice of medicine, and the decision to prescribe a particular drug is clearly dissociated from the decision to include the patient in the study.

Eligible participants will meet the local reimbursement criteria. The study will be managed by IQVIA. No patient-identifying information will be transferred to the sponsor nor the CRO.

No visits should be scheduled specifically for this observational study, data will be collected at usual asthma healthcare visits (routine or unscheduled, remote or face to face). If a participant is seen by their physician for monthly mepolizumab injections, data for healthcare utilization, asthma medications and any recent lung function assessment will be collected on a monthly basis. When the participant is seen less frequently by their physician (for example when mepolizumab injection is given at a different site or at home) this data will be collected at usual asthma healthcare visits, which are likely to occur less frequently.

The index date will be defined as the date of the first mepolizumab injection administration during the study (i.e. treatment initiation). To accommodate local healthcare practice, this will be according to local healthcare practice.
