Title: A Phase 3, Open-label Study Evaluating the Long Term Safety and Efficacy of VX-659 Combination Therapy in Subjects With Cystic Fibrosis Who Are Homozygous or Heterozygous for the F508del Mutation
Brief Summary: This study will evaluate the long-term safety and tolerability of VX-659 in triple combination (TC) with tezacaftor (TEZ) and ivacaftor (IVA) in subjects with cystic fibrosis (CF) who are homozygous or heterozygous for the F508del mutation.


Options:
A: Inclusion Criteria:

* Completed study drug treatment in a parent study; 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.
B: 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

  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.
