Identifying lung biomarkers in patients with ASMD

Biomarkers Of Lung InVolvement In ASMD

Not applicable Interventional Academisch Medisch Centrum - Universiteit van Amsterdam (AMC-UvA) · NCT05914727

This study is trying to find specific substances in the breath of people with Acid Sphingomyelinase Deficiency to see if they can help us understand lung problems better compared to healthy individuals.

What this trial studies

This study aims to characterize the breath profiles of patients with Acid Sphingomyelinase Deficiency (ASMD) by analyzing their exhaled breath and condensate in comparison to healthy controls. Participants will provide breath samples through various methods to identify specific volatile and non-volatile compounds that may indicate inflammatory or fibrotic processes in the lungs. The study includes both a cross-sectional case-control component and a prospective cohort component to gather comprehensive data on potential biomarkers for lung injury in ASMD patients.

Who should consider this trial

Good fit: Ideal candidates for this study are patients aged 12 and older with a confirmed diagnosis of the chronic visceral subtype of ASMD.

Not a fit: Patients who are unable to adhere to the study protocol or cannot complete spirometry tests may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to the identification of biomarkers that help determine which ASMD patients may benefit from upcoming enzyme replacement therapies.

How similar studies have performed: While the approach of using breath analysis for lung disease is established, this specific application in ASMD is novel and has not been extensively tested.
