Longitudinal study of asthma in urban children and adolescents

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This observational study follows 250 urban children and adolescents with asthma and 60 without asthma over a one-year period. Participants aged 6-17 will be monitored for their asthma symptoms and cold symptoms, with scheduled visits throughout the year. The study aims to establish phenotypic characteristics and gather data on the impact of asthma and respiratory symptoms in this population. Participants with asthma must be on daily controller therapy, while those without asthma must not have used asthma medications in the past year.

10. Use of investigational drugs within 4 weeks of enrollment
11. Have past or current medical problems or findings from physical examination or laboratory testing that are not listed above, which, in the opinion of the site investigator, may pose additional risks from participation in the study, may interfere with the participant's ability to comply with study requirements or that may impact the quality or interpretation of the data obtained from the study
12. If in the asthma group, will not allow the study clinician, an asthma specialist, to manage their disease for the duration of the study or who are not willing to change their asthma medications to follow Protocol CAUSE-03 CHEETAH
13. If in the non-asthma group, having bronchodilator reversibility (improvement in Forced expiratory volume in 1 second (FEV1) with albuterol \> = 10%) at the Screening/Enrollment visit
14. Have had a life-threatening asthma exacerbation in the last 2 years requiring intubation, mechanical ventilation or resulting in a hypoxic seizure. Potential participants may be reassessed as outlined in the Protocol CAUSE-03 Manual of Procedures (MOP)
