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.


Options:
A: 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
* Use of strong inhibitors, moderate inducers or strong inducers of Cytochrome P450 3A (CYP3A) within 14 days before Day 1 of dosing
B: 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
C: Inclusion Criteria:

* Documentation of a CF diagnosis as evidenced by 1 or more clinical features consistent with the CF phenotype and 1 or more of the following criteria:

  1. Sweat chloride equal to or greater than 60 mEq/L by quantitative pilocarpine iontophoresis test;
  2. Two well-characterized mutations in the CFTR gene
* FEV1 ≥ 40% predicted corrected
* Stable treatment of CF for 14 days before Visit 1

Exclusion Criteria:

* Severe or unstable CF, such as:

  1. Intravenous antibiotic treatment within 14 days before Visit 1
  2. Treatment with any corticosteroids \> 10 mg per day or \> 20 mg every other day oral prednisone or equivalent within 14 days before Visit 1
* Any one of the following values for laboratory tests at Screening:

  1. A positive pregnancy test (or at Visit 1);
  2. Hemoglobin \< 10 g/dL
  3. Neutrophils \< 1.0 x 10\~9/L
  4. Platelets \< 75 x 10\~9/L
  5. Creatinine clearance \< 50 ml/min according to modified Cockcroft-Gault equation
  6. Serum transaminases \> 2.5 x upper normal limit
  7. Total bilirubin ≥ 1.5 x upper limit of normal
* Any other condition that, in the opinion of the Principal Investigator, is clinically significant and may put the subject at greater safety risk, influence response to study product, or interfere with study assessments.
D: Inclusion Criteria:

* Completed study drug treatment in a parent study i.e.VX17-445-102 (NCT03525444) and VX17-445-103 (NCT03525548); or had study drug interruption(s) in a parent study but completed study visits up to the last scheduled visit of the Treatment Period in the parent study.

Exclusion Criteria:

* History of drug intolerance in a parent study that would pose an additional risk to the subject in the opinion of the investigator.
* Current participation in an investigational drug trial (other than a parent study)

Other protocol defined Inclusion/Exclusion criteria may apply.
