Breath analysis for patients with severe asthma

The BASA Study: Breath Analysis for Severe Asthma Patients. A New, Non-invasive Approach for the Monitoring of Inflammation in Severe Asthma Patients on Biologics

Observational Azienda Ospedaliera Universitaria Policlinico Paolo Giaccone Palermo · NCT05946421

This study is testing how biologic treatments change breath markers in people with severe asthma to see how they affect lung function and inflammation.

What this trial studies

This observational study evaluates the fluctuations of exhaled breath markers in patients with severe asthma who are receiving biologic treatments. Participants will be monitored for up to 16 weeks to assess lung function and inflammation using non-invasive technologies such as exhaled breath analysis. A control group will be followed for up to two weeks to compare the modifications of inflammation markers. The goal is to identify how biologic treatments affect these markers in severe asthma patients.

Who should consider this trial

Good fit: Ideal candidates are individuals diagnosed with severe asthma who are eligible for or currently receiving biologic treatment.

Not a fit: Patients who cannot perform lung function measurements or have acute infections may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved monitoring and management of severe asthma through non-invasive breath analysis.

How similar studies have performed: Other studies have shown promise in using breath analysis for monitoring asthma, suggesting this approach may be beneficial.
