Title: A Phase 1, Randomized, Single-Dose, Open-Label Crossover Study to Investigate the Effect of Food on the Relative Bioavailability of 2 Fixed-Dose Combinations of Lumacaftor and Ivacaftor Tablet Formulations in Healthy Adult Subjects
Brief Summary: This study is designed to investigate the effect of food on the relative bioavailability of 2 different strengths of fixed-dose combinations of lumacaftor and ivacaftor tablet formulations.


Options:
A: Inclusion Criteria:

* Healthy male and female subjects as defined in the protocol
* Subjects who weigh \>50 kg at Screening

Exclusion Criteria:

* History of any illness or condition that might confound the results of the study or pose an additional risk to the subject upon administration of study drug - Positive for hepatitis B,C, or HIV
* Standard 12-lead ECG demonstrating QTc \>450 msec for male subjects and \>480 msec for female subjects at the Screening Visit
* Abnormal renal function as defined in the protocol at Screening
* Forced expiratory volume in 1 second (FEV1) \<80% predicted at the Screening Visit
* Blood donation (of approximately 1 pint \[500 mL\] or more) within 56 days before the first dose of study drug
* Treatment with an investigational drug or device within 30 days or 5 half-lives preceding the first dose of study drug
B: Inclusion Criteria:

1. Male or female subject ≥ 18 years of age, on the day of signing the Informed Consent Form (ICF).
2. A confirmed clinical diagnosis of CF.
3. One F508del mutation on one allele in the CFTR gene, a gating (class III) mutation (one of the following: G551D, G1244E, G1349D, G178R, G551S, S1251N, S1255P, S549N, or S549R) on the 2nd allele in the CFTR gene (documented in the subject's medical record or CF registry).
4. Weight ≥ 40 kg.
5. Stable concomitant treatment for at least 4 weeks (28 days) prior to baseline (including physician prescribed ivacaftor (Kalydeco®) 150 mg b.i.d.).
6. Forced expiratory volume in 1 second (FEV1) ≥ 40% of predicted normal for age, gender and height at screening (pre- or postbronchodilator).

Exclusion Criteria:

1. History of clinically meaningful unstable or uncontrolled chronic disease that makes the subject unsuitable for inclusion in the study in the opinion of the investigator.
2. Unstable pulmonary status or respiratory tract infection (including rhinosinusitis) requiring a change in therapy within 4 weeks of baseline.
3. Need for supplemental oxygen during the day, and \>2 liters per minute (LPM) while sleeping.
4. History of hepatic cirrhosis with portal hypertension (e.g., signs/symptoms of splenomegaly, esophageal varices, etc).
5. Abnormal liver function test at screening; defined as aspartate aminotransferase (AST) and/or alanine aminotransferase (ALT) and/or alkaline phosphatase and/or total bilirubin (\>1.5 times ULN (CTCAE Grade 2) and/or gamma-glutamyl transferase (GGT) ≥ 3x the upper limit of normal (ULN), and/or total bilirubin (\>1.5 times ULN (CTCAE Grade 2).
6. Estimated creatinine clearance \< 60mL/min using the Cockroft-Gault formula at screening.
C: Inclusion Criteria:

* Cystic fibrosis patients homozygous for the F508del mutation as confirmed by genetic test
* Aged 14 years and older
* Male or female (non-pregnant women who are to remain non-pregnant for 3 months after the end of the study)
* FEV1 \> 50% of predicted normal

Exclusion Criteria:

* Acute respiratory tract infection or pulmonary exacerbation requiring antibiotic intervention within 2 weeks of visit 1
* Any condition prohibiting the correct measurement of the NPD such as respiratory tract infection
* Active or passive smoking
* Allergic chronic rhinitis
* History of significant lactose intolerance
* History of neuropathy
* History of cataracts or known increased risk of cataract formation
* Hypersensitivity to miglustat or any excipients
* Planned treatment or treatment with another investigational drug or therapy within 1 month prior to randomisation
D: 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
