Title: A Phase 3, Randomized, Double Blind, Placebo Controlled, Parallel Group Study to Evaluate the Efficacy and Safety of Lumacaftor in Combination With Ivacaftor in Subjects Aged 12 Years and Older With Cystic Fibrosis, Homozygous for the F508del CFTR Mutation
Brief Summary: The primary objective of the study was to evaluate the efficacy of lumacaftor in combination with ivacaftor at Week 24 in participants aged 12 years and older with cystic fibrosis (CF) who are homozygous for the F508del mutation on the CF transmembrane conductance regulator (CFTR) gene.

* Stable CF disease as judged by the investigator
* Forced expiratory volume in 1 second (FEV1) at least 40% and not greater than 90% of predicted

Exclusion Criteria:

* History of any comorbidity that might confound the results of the study, interfere with the use of cardiopulmonary exercise tests (CPETs) as an assessment, or pose an additional risk in administering study drug to the subject
* Any previous exposure to LUM or IVA
* History of cardiac arrhythmia, ischemic heart disease, congestive heart failure, or other clinically significant cardiac condition, or medical condition requiring chronic use of a beta blocker, non-dihydropyridine calcium channel blocker, or other cardiac medication known to affect exercise tolerance
* History of solid organ or hematological transplantation
* For subjects under 18 years of age at Screening, except those who have had bilateral lens removal, selected findings on a screening ophthalmologic examination will be exclusionary
* Using or expected to require any concomitant medication that is prohibited in this study
* History of alcohol or drug abuse, as deemed by the investigator, in the past year, including but not limited to cannabis, cocaine, and opiates
* Participation in an investigational drug study within 30 days before the Screening Visit
* Pregnant or nursing females; males with a female partner who is pregnant or nursing
* Colonization with organisms associated with a more rapid decline in pulmonary status
C: Inclusion Criteria:

* Confirmed diagnosis of CF
* Homozygous for the F508del CFTR mutation
* 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
* Willing to remain on a stable CF medication regimen through Week 24 or, if applicable, the Safety Follow up Visit

Exclusion Criteria:

* An acute upper or lower respiratory infection, pulmonary exacerbation, or changes in therapy (including antibiotics) for pulmonary disease within 4 weeks before first dose of study drug
* History of solid organ or hematological transplantation
* History of alcohol or drug abuse in the past year
* Ongoing or prior participation in an investigational drug study (including studies investigating lumacaftor and/or ivacaftor) within 30 days of screening.

D: Inclusion Criteria:

* Clinically stable CF patients
* Age \> 18 years

Exclusion Criteria:

* FEV1 \< 25%.
* Patients on the waiting list for lung transplantation and those who have undergone lung transplantation.
* Patients with an exacerbation in the four weeks prior to the study. For the purpose of this study pulmonary exacerbation will be defined as acute or subacute worsening of respiratory symptoms which warrant change in treatment (i.e., new oral or intravenous antibiotics). Patients can undergo testing once they are finished their antibiotics and deemed clinically stable.
* Patients dependent on supplemental oxygen for exercise.
* Pregnancy
* Participation in another clinical trial up to 4 weeks prior to the first baseline visit
