Title: A Phase 3, Two-Arm, Rollover Study to Evaluate the Safety of Long Term Ivacaftor Treatment in Subjects 6 Years of Age and Older With Cystic Fibrosis and a Non-G551D CFTR Mutation
Brief Summary: The purpose of this study is to evaluate the safety of long-term ivacaftor treatment in participants with cystic fibrosis (CF) from Studies 110 (NCT01614457), 111 (NCT01614470), and 113 (NCT01685801).


Options:
A: Inclusion Criteria:

* Participants from Study 110 or Study 111 entering the ivacaftor arm must have completed the assigned study drug treatment duration in the previous study.
* Participants from Study 113 entering the ivacaftor arm must have completed all study related treatments through the Follow-up Visit and met the Study 113 responder criteria during the previous study.
* Participants entering the observational arm must have completed at least 4 weeks of study drug treatment in their previous study (Study 110 or Study 111), must have completed the previous study but do not wish to enroll in the ivacaftor arm, or must have completed the previous study but do not meet the inclusion criteria of the ivacaftor arm.
* Participants of childbearing potential entering the ivacaftor arm must not be pregnant.
* Participants entering the ivacaftor arm must be willing to comply with contraception requirements.

Exclusion Criteria (Ivacaftor Arm Only):

* History of any illness or condition that might confound the results of the study or pose an additional risk in administering ivacaftor to the Participant.
* Use of moderate or strong inhibitors or inducers of cytochrome P450 (CYP) 3A.
* Evidence of cataract or lens opacity at or before the Day 1 Visit.
B: Inclusion Criteria:

* Weighing at least 15 kg
* Confirmed diagnosis of cystic fibrosis (CF) and G551D mutation in at least 1 allele
* Forced expiratory volume in 1 second (FEV1) of 40% to 105% (inclusive) of predicted normal for age, gender, and height (Knudson standards) at Screening
* Able to swallow tablets
* As judged by the investigator, parent or legal guardian and subject must have been able to understand protocol requirements, restrictions, and instructions, and the parent or legal guardian should have been able to ensure that the subject complied with, and was likely to complete, the study as planned
* Parent or legal guardian must have signed the informed consent form and corresponding assent must be obtained from the subject
* Willing to use at least 1 highly effective birth control method during the study
* No clinically significant abnormalities that would have interfered with the study assessments, as judged by the investigator

Exclusion Criteria:

* History of any illness or condition that might confound the results of the study or pose an additional risk in administering study drug to the subject
* Acute respiratory infection, pulmonary exacerbation, or changes in therapy for pulmonary disease within 4 weeks of Day 1 of the study
* Abnormal liver function ≥ 3x the upper limit of normal
* Abnormal renal function at Screening
* History of solid organ or hematological transplantation
* Ongoing participation in another therapeutic clinical study or prior participation in an investigational drug study within 30 days prior to Screening
* Use of inhaled hypertonic saline treatment
* Concomitant use of any inhibitors or inducers of cytochrome P450 3A4 (CYP 3A4)
C: Inclusion Criteria:

* Confirmed diagnosis of CF by sweat chloride value or CF mutation criteria.
* Have 1 of the following 10 CFTR mutations on at least 1 allele: G551D, G178R, S549N, S549R, G551S, G1244E, S1251N, S1255P, G1349D or R117H (eligible in regions where ivacaftor is approved for use). Part A/B group may also have other ivacaftor-responsive mutations.
* Hematology, serum chemistry, and vital signs results at screening with no clinically significant abnormalities that would interfere with the study assessments, as judged by the investigator.

Exclusion Criteria:

* History of any illness or 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 participant
* Colonization with organisms associated with a more rapid decline in pulmonary status at screening (Only for Parts A and B)
* History of abnormal liver function or abnormal liver function at screening
* History of solid organ or hematological transplantation
* Use of any moderate or strong inducers or inhibitors of cytochrome P450 (CYP) 3A within 2 weeks before Day 1
* Participation in a clinical study involving administration of either an investigational or a marketed drug within 30 days or 5 terminal half-lives before screening
* Hemoglobin (Hgb) \<9.5 g/dL at screening
* Chronic kidney disease of Stage 3 or above
* Presence of a non-congenital or progressive lens opacity or cataract at Screening

Other protocol defined Inclusion/Exclusion Criteria may apply.
D: Inclusion Criteria:

* Male or female subjects with confirmed diagnosis of CF
* Must have the G551D-CFTR mutation in at least 1 allele
* FEV1 \>90% of predicted normal for age, gender, and height

Exclusion Criteria:

* Ongoing participation in another therapeutic clinical study or prior participation in an investigational drug study within the 30 days prior to screening
* Use of inhaled hypertonic saline treatment within 2 weeks of the Period 1, Day 1 visit
