Investigators
Eligibility Criteria
Inclusion Criteria
- •Homozygous for the F508del-CFTR mutation; historical genotype must be documented in the participant's source documents.
- •Percent predicted FEV1 \<40 of adjusted for age, sex, and height at Screening
Exclusion Criteria
- •Participant currently receiving invasive mechanical ventilation.
- •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
- •Any clinically significant laboratory abnormalities at screening that would interfere with the study assessments or pose an undue risk for the subject
- •A 12-lead electrocardiograms (ECG) demonstrating QTcF \>450 msec at Screening
- •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.
- •Use of strong inhibitors, moderate inducers, or strong inducers of CYP3A
- •Pregnant and nursing females: Females of childbearing potential must have a negative pregnancy test at Screening and Day
- •Sexually active subjects of reproductive potential who are not willing to follow the contraception requirements
Arms & Interventions

Lumacaftor 400 milligram (mg) and ivacaftor 250 mg combination tablet orally twice daily for 24 weeks.
Intervention: Lumacaftor
Lumacaftor/Ivacaftor combination
Lumacaftor 400 milligram (mg) and ivacaftor 250 mg combination tablet orally twice daily for 24 weeks.

Outcomes
Primary Outcomes
Number of Participants With Treatment Emergent Adverse Events (AEs) or Serious Adverse Events (SAEs)
Time Frame: Day 1 up to Week 28
AE: any untoward medical occurrence in a participant during the study; event does not necessarily have a causal relationship with treatment. This includes any newly occurring event/previous condition that has increased in severity/frequency after informed consent form is signed. AE includes serious as well as non-serious AEs. SAE (subset of AE): medical event, which falls into any of the following categories, regardless of its relationship to study drug: death, life threatening adverse experience, in-patient hospitalization/prolongation of hospitalization, persistent/significant disability or incapacity, congenital anomaly/birth defect, important medical event. TEAEs: AEs that started/ worsened on/after the start of study drug through the Safety Follow up Visit (4 weeks after the last dose of study drug). Results were reported as planned, as a combined single LUM/IVA arm irrespective of permitted dose modification.
Secondary Outcomes

- Absolute Change From Baseline in Sweat Chloride at Average of Day 15 and Week 4(Baseline, Day 15 and Week 4)
- Number of Hospitalizations(Baseline through Week 24)
- Absolute Change From Baseline in Cystic Fibrosis Questionnaire - Revised (CFQ-R) Respiratory Domain Score Through Week 24(Baseline, Through Week 24)
- Absolute Change From Baseline in Forced Expiratory Volume in 1 Second (FEV1) Up to Week 24(Baseline, Up to Week 24)
- Duration For Which Participants Received Intravenous (IV) Antibiotics(Baseline through Week 24)
