Classification of severe bronchopulmonary dysplasia in infants

Multidimensional Phenotype Classification in Grade 3 Bronchopulmonary Dysplasia

Observational Children's Hospital of Philadelphia · NCT06475976

This study is trying to create a new way to classify the most severe form of bronchopulmonary dysplasia in infants to see how different types of the condition affect their breathing and brain development over time.

What this trial studies

This observational study focuses on infants diagnosed with grade 3 bronchopulmonary dysplasia (BPD), the most severe form of this chronic lung disease. It aims to create an empirically defined classification system for grade 3 BPD using a variety of objective cardiopulmonary diagnostic, clinical, and biological data. The study will also explore the relationship between different phenotype subgroups and their neurodevelopmental and respiratory outcomes up to two years of corrected age. By employing advanced diagnostic technologies, the study seeks to better characterize disease heterogeneity and improve outcome predictions for affected infants.

Who should consider this trial

Good fit: Ideal candidates for this study are infants born with a gestational age of less than 32 weeks who are receiving invasive ventilation and have been diagnosed with grade 3 BPD.

Not a fit: Patients who are unlikely to survive the diagnostic period or have severe congenital abnormalities not representative of BPD may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to more effective, phenotype-targeted therapies for infants with severe bronchopulmonary dysplasia.

How similar studies have performed: While the approach of multidimensional phenotyping is novel in the context of grade 3 BPD, similar methodologies have shown success in other heterogeneous lung diseases.
