Title: A Phase 2, Multicenter, Double-Blinded, Placebo-Controlled, Multiple-Dose Study to Evaluate Safety, Tolerability, Efficacy, Pharmacokinetics, and Pharmacodynamics of Lumacaftor Monotherapy, and Lumacaftor and Ivacaftor Combination Therapy in Subjects With Cystic Fibrosis, Homozygous or Heterozygous for the F508del-CFTR Mutation
Brief Summary: The purpose of this study is to evaluate of the safety, efficacy, pharmacokinetics (PK) and pharmacodynamic (PD) effects of lumacaftor (VX-809) alone and when coadministered with ivacaftor (VX-770) in participants with cystic fibrosis, homozygous or heterozygous for the F508del-CFTR mutation.


Options:
A: Inclusion Criteria:

1. Male or female, age ≥ 18 years with confirmed diagnosis of CF, homozygous for the F508del-CFTR mutation based on historical results generated by Ambry Genetics within the past two years or if unavailable, confirmed by testing done within the past 28 days
2. Sweat chloride ≥ 60 (milliequivalents) mEq/L, by quantitative pilocarpine iontophoresis test (QPIT) at screening
3. Weight ≥ 40 kg at screening
4. Forced expiratory volume (FEV1) ≥ 40% of predicted normal for age, gender, and height (Hankinson standards) pre- or post-bronchodilator value, at screening
5. Oxygen saturation by pulse oximetry ≥ 90% breathing ambient air, at screening
6. Hematology, clinical chemistry and urinalysis results with no clinically significant abnormalities that would interfere with the study assessments at screening

Exclusion Criteria:

1. Any acute infection, including acute upper or lower respiratory infections and pulmonary exacerbations that require treatment or hospitalization within 2 weeks of Study Day 1
2. Any change in chronic therapies for CF lung disease (e.g., Ibuprofen, Pulmozyme®, hypertonic saline, Azithromycin, Tobi®, Cayston®) within 4 weeks of Study Day 1
3. Blood hemoglobin \< 10 g/dL at screening
4. Serum albumin \< 2.5 g/dL at screening
5. Abnormal liver function defined as ≥ 3 x upper limit of normal (ULN) in 3 or more of the following: aspartate aminotransferase (AST), alanine aminotransferase (ALT), g-glutamyl transferase (GGT), alkaline phosphatase (ALP), or total bilirubin at screening
6. History of abnormal renal function (creatinine clearance \< 50 mL/min using Cockcroft-Gault equation) within a year of screening
7. History, including the screening assessment, of ventricular tachycardia or other ventricular arrhythmias
8. History, including the screening assessment, of prolonged cardiac QT interval and/or QTcF (QT with Fridericia's correction) interval (\> 450 msec)
9. History of solid organ or hematological transplantation
10. History of alcohol abuse or drug abuse (including cannabis, cocaine, and opioids) in the year prior to screening
11. Use of continuous (24 hr/day) or nocturnal supplemental oxygen
B: Inclusion Criteria:

* Heterozygous for F508del-CFTR and a second allele with a CFTR mutation predicted to have residual function
* Forced Expiratory Volume in 1 Second (FEV1) greater than or equal to (≥) 40 percent (%) and less than or equal to (≤) 90% of predicted normal for age, sex, and height during screening
* Sweat chloride value ≥60 millimole per liter (mmol/L) during screening OR as documented in the participant's medical record
* Stable CF disease as judged by the investigator

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
* History of solid organ or hematological transplantation
* Ongoing or prior participation in an investigational drug study (including studies investigating VX-661, lumacaftor \[VX-809\], and/or ivacaftor) within 30 days of screening
* Pregnant and nursing females
* Sexually active participants of reproductive potential who are not willing to follow the contraception requirements
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.
* History of alcohol abuse or drug addiction in the past year, including cannabis, cocaine, and opiates.
* Ongoing participation in another therapeutic clinical study, or prior participation in an investigational drug study without appropriate washout
* Pregnant or nursing females; females of childbearing potential who are unwilling or unable to use an acceptable method of non-hormonal contraception
* 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
* Heterozygous participants who participated in Cohort 2 and meet the eligibility criteria for Cohort 4 may participate in Cohort 4
* Evidence of lens opacity or cataract as determined by the ophthalmologic examination (Cohort 4 only)
D: Inclusion Criteria:
