Willing to remain on a stable CF treatment regimen through completion of study participation. Inclusion criteria for subjects resuming participation in Part A of this study after enrolling in another qualifying Vertex study include all of the criteria above AND the following criterion: 6. Completed the ETT visit in another qualified Vertex study before or on same day as the Returning Visit in this study. If more than 30 days have elapsed since the ETT visit in the other qualified Vertex study, approval of the medical monitor is required. Part B: Subjects who meet all of the following criteria will be eligible for Part B: 1.

Exclusion criteria

Exclusion criteria: Part A Subjects who meet any of the following criteria will NOT be eligible for Part A: 1.

Pregnant and breast-feeding females. All female subjects, regardless of childbearing potential status, must have a negative pregnancy test at the Part A Day 1 Visit before receiving the first dose of study drug. 3. History of intolerance to study drug in the parent study that would pose an additional risk to the subject in the opinion of the investigator. (e.g., subjects with a history of allergy or hypersensitivity to the study drug). 4. Current participation in an investigational drug study (other than the parent study). Participation in a non-interventional study (including observational studies, registry studies, and studies requiring blood collections without administration of study drug) and screening for another Vertex study is permitted. Subjects resuming participation in Part A of this study after enrolling in another qualifying Vertex study must not meet Exclusion Criteria 1 through 3, and also must not meet any of the following criteria: 5. Pregnant and nursing females. All female subjects must have a negative pregnancy test at the Returning Visit before receiving the first dose of study drug. 6. History of intolerance to study drug that would pose an additional risk to the subject in the opinion of the investigator. If protocol-defined interruption criteria is met in another qualified Vertex study, then the subject must remain on study drug interruption until the subject meets criteria in Section 9.8 and receives approval by the medical monitor to resume study drug dosing in this study. 7. Has received the first dose of study drug in the Treatment Period of another qualified Vertex study. 8. Has access to commercially available VX-445/TEZ/IVA or is receiving managed access program supplied VX 445/TEZ/IVA. 9. Has departed this study more than once to participate in another qualified Vertex study. Part B: Subjects who meet any of the following criteria will NOT be eligible for this study: 1. History of any illness or any clinical condition that, in the opinion of the investigator, might confound the results of the study or pose an additional risk in administering study drug to the subject. 2.
