- Target Recruitment
- 510
Subjects must meet all of the following inclusion criteria to be eligible for participation in this study.
-
Current participant or willingness to participate in the CFF patient registry database
-
≥ 6 years of age
-
Subject has CF as diagnosed by one of the following
- Documented sweat chloride ≥ 60 mEq/L by quantitative pilocarpine iontophoresis test, or
- Two well-characterized genetic mutations in the CFTR gene, or
- Abnormal nasal potential difference (NPD) AND accompanying clinical characteristics consistent with CF. For subjects who lack documentation of either a positive sweat chloride test or an abnormal NPD, and who have only one well-characterized genetic mutation of the CFTR gene, the diagnosis of CF is determined by the Investigator.
-
FEV1 ≥ 25% predicted and ≤ 90% predicted.
-
≥ 2 lower respiratory tract cultures positive for PA with results documented in the subject's medical history.
-
Subject must be able to provide written informed consent/assent prior to any study related procedure; parent/guardian must be able to give written informed consent as necessary prior to any study related procedure.
