* Stable CF disease as judged by the investigator
* Willing to remain on a stable CF medication regimen through Week 24 or, if applicable, the Safety Follow up Visit

Exclusion Criteria:

* History of any comorbidity 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.
* An acute upper or lower respiratory infection, pulmonary exacerbation, or changes in therapy (including antibiotics) for pulmonary disease within 28 days before Day 1 (first dose of study drug)
* Pregnant or nursing females (females of childbearing potential must have a negative pregnancy test at Screening and Day 1)
* Sexually active participants of reproductive potential who are not willing to follow the contraception requirements
B: Inclusion Criteria:

* Subject voluntarily agrees to participate in this study and signs an Institutional Review Board (IRB)-approved informed consent prior to performing any of the screening procedures and in the opinion of the PI complies with all the requirements of the study.
* Subject is healthy, determined at the screening medical evaluation (including but not limited to medical history, physical examination and clinical laboratory evaluations).
* Subject is Caucasian.
* Female subject must be of non-childbearing potential (surgically sterile \[hysterectomy or bilateral tubal ligation\] or post-menopausal ≥ 1 year with follicle stimulating hormone \[FSH\] \> 40 U/L). Women receiving hormone replacement therapy (HRT) are eligible to enroll.
* Male subject must agree to use condoms and refrain from sperm donation from Day 1 until 30 days post last dose or have documentation of vasectomy.
* Subject has a body weight \> 50 kg and body mass index (BMI) between 19.5 and 32 kg/m2, inclusive, at screening.
* Subject has no clinically significant abnormal findings related to their systolic or diastolic blood pressure (BP), per the investigator's judgment, at screening or Day 1.
* Subject has no clinically significant abnormal findings in 12 lead ECG, per the investigator's judgment, at screening.

Exclusion Criteria:

* Subject has clinically significant history or evidence of cardiovascular, respiratory, hepatic, renal, gastrointestinal, endocrine, neurological, immunological, or psychiatric disorder(s) as determined by the investigator or designee.
* Subject has clinically significant abnormalities on a 12 lead ECG done at screening
* Subject has clinically significant abnormalities on a 48-hour ambulatory ECG done at screening
* Subject has any disorder that would interfere with the absorption, distribution, metabolism, or excretion of drugs.
* Subject has any concurrent disease or condition that, in the opinion of the investigator, would make the subject unsuitable for participation in the clinical study.
* Subject is unlikely to comply with the protocol requirements, instructions, and study related restrictions; e.g., uncooperative attitude, unavailable for follow-up call, and/or improbability of completing the clinical study.
C: Inclusion Criteria:

* Male or female participants with confirmed diagnosis of CF
* Must have the F508del-CFTR mutation on at least 1 allele.
* FEV1 greater than equal (\>=) 40% of predicted normal for age, gender, and height (Knudson standards)(Cohort 1, 2, and 3); FEV1 40-90% of predicted normal for age, gender, and height (Hankinson standards (Cohort 4)
* Participant of child-bearing potential and who are sexually active must meet the contraception requirements

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 (e.g., cirrhosis with portal hypertension).
* An acute illness including acute upper or lower respiratory infection, pulmonary exacerbation or changes in therapy (including antibiotics) for pulmonary disease within 14 days (Cohort 1, 2, and 3) or 28 days (Cohort 4) before receiving the first dose of study drug.
* History of solid organ or hematological transplantation.

* Participants enrolled in Cohort 1 or Cohort 2 will not be eligible for Cohort 3
* Ongoing or prior participation in an investigational drug study within 30 days of the Screening Visit
