What this trial studies

This is a multi-center, non-interventional registry aimed at creating and maintaining a database of participants for current and future studies on childhood asthma in urban settings. Approximately 1,500 participants of all ages will be enrolled from selected metropolitan areas. The registry will gather data during a core visit and may include optional follow-up visits, assessing various asthma and allergy characteristics. Healthy controls may also be invited to participate for validation and training purposes, ensuring a comprehensive approach to participant recruitment.

Why it matters

Potential benefit: If successful, this registry could enhance the understanding of asthma in urban settings and improve recruitment for future studies, ultimately leading to better asthma management strategies.

How similar studies have gone: Other studies utilizing similar registry approaches have shown promise in enhancing participant recruitment and data collection, indicating a potentially successful methodology.
