CF patients enrolled in this protocol will be recruited from patients followed by the Adult CF Program at National Jewish Health. Patients will be selected based on planned use of a CFTR modulator by their primary physician. No patient will be started on (or will switch) CFTR modulator agents for the purpose of the study. After enrollment, biological samples may be collected at two different time points prior to treatment initiation. One set of samples will be collected at baseline health prior to CFTR modulator initiation or change. A second set of samples will be obtained in subjects at the time of acute pulmonary exacerbation, if one occurs prior to CFTR modulator initiation or change. Post CFTR modulator initiation study assessments will be obtained at least one month after starting treatment and continue up to 2 times a year (including during pulmonary exacerbations), in order to document longitudinal effects of therapies and changes in inflammatory biology over time. At the time of each biological sampling, blood, sputum sample, urine, and a quality of life assessment will be acquired in all enrolled subjects. In addition to demographic data, clinical data, such as quantitative microbiology and simple spirometry will be recorded at the time of sample collection.
