Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The study is a breath biomarker validation study. It is anticipated that 300 patients with cystic fibrosis (CF) from 5 clinical sites in the USA will be enrolled. The study is funded by the US NIH and the US Cystic Fibrosis Foundation. Enrollment commenced in May 2019. Sputum, induced sputum, and oropharyngeal swabs will be collected and evaluated at each clinic as part of standard clinical practice. Excess sputum will be sent to Children's Colorado Hospital for molecular analysis. No swabs will be sent anywhere (other than the clinic from which they originate). Breath samples will be taken from all study participants.
