Improving diagnosis and treatment for children with asthma

Advancing Diagnosis and Treatment of Pediatric Asthma by Deep Immunophenotyping and Evaluation of Two Spacer Devices for Inhaled Corticosteroid Administration

Not applicable Interventional Luxembourg Institute of Health · NCT07500246

This project will test whether a digital inhaler and spacer system helps children aged 5–16 with partly controlled or uncontrolled asthma take their inhaled corticosteroids more reliably, improve asthma control, and help identify noninvasive biomarkers and environmental triggers that affect treatment.

What this trial studies

Children aged 5 to 16 with partly controlled or uncontrolled asthma who use MDI-based inhaled corticosteroids will use a digital inhaler and spacer system (Whizz spacer system, AeroChamber Plus® Flow-Vu®) while researchers monitor inhalation technique and medication adherence. The study will collect noninvasive biomarker samples and track environmental exposures to explore links with diagnosis and treatment response. Outcomes will include changes in adherence, asthma control, and candidate biomarkers that correlate with response, plus analyses of how environmental factors modify outcomes. Findings aim to combine device-based adherence support with biomarker and exposure data to guide more personalized asthma care.

Who should consider this trial

Good fit: Children aged 5–16 with a physician diagnosis of asthma requiring controller therapy with inhaled corticosteroids (with or without LABA) via MDI and who have partly controlled or uncontrolled asthma, with consent from a legally authorized representative and assent when applicable, are ideal candidates.

Not a fit: Children with severe asthma (per GINA), recent systemic corticosteroid treatment for exacerbation, active respiratory infection, other chronic lung diseases, significant immunodeficiency or immunosuppression, current immunotherapy (where excluded), or those outside the 5–16 age range are unlikely to benefit from this study.

Why it matters

Potential benefit: If successful, this approach could help children use inhalers more effectively, reduce symptoms, and support more personalized treatment decisions using biomarkers and exposure data.

How similar studies have performed: Prior studies have shown that digital inhaler feedback and spacers can improve inhalation technique and adherence, while biomarker-driven and environmental approaches to personalize asthma care are promising but still emerging.
