Title: A Phase 1b, Randomized, Double-Blind, Placebo-Controlled, Dose Escalation Study of N6022 to Evaluate Safety and Pharmacokinetics in Subjects With Cystic Fibrosis Homozygous for the F508del-CFTR Mutation (SNO1)
Brief Summary: The purpose of this study is to investigate the safety, tolerability and pharmacokinetics of N6022, and to obtain descriptive information on the effect of N6022 on biomarkers of CFTR function and inflammation in adult cystic fibrosis subjects who are homozygous for the F508del-CFTR mutation.


Options:
A: Inclusion Criteria:

Subjects entering the Treatment Cohort must meet both of the following criteria:

* Completed study visits up to Week 24 of Study 109 or Week 26 of Study 011B and did not permanently discontinue treatment
* Willing to remain on a stable CF medication through the Safety Follow-up Visit.

Subjects entering the Observational Cohort must meet 1 of the following criteria:

* Completed 24 weeks of study drug treatment in Study 109 or completed 24 weeks of study drug treatment and the Week 26 Safety Follow up in Study 011B.
* Received at least 4 weeks of study drug and completed visits up to Week 24 of Study 109 or Week 26 of Study 011B.

Exclusion Criteria (Treatment Cohort Only):

* History of any comorbidity or laboratory abnormality 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 subject (e.g., cirrhosis with portal hypertension).
* Pregnant and nursing females.
* Sexually active subjects of reproductive potential who are not willing to follow the contraception requirements.
* History of drug intolerance in the prior study that would pose an additional risk to the subject in the opinion of investigator
* History of poor compliance with study drug and/or procedure in the previous study as deemed by the investigator.
* Participation in an investigational drug trial (including studies investigating lumacaftor and/or ivacaftor).
B: Key Inclusion Criteria:

* Homozygous for the F508del mutation (F/F)
* Forced expiratory volume in 1 second (FEV1) value ≥40% and ≤90% of predicted mean for age, sex, and height

Key Exclusion Criteria:

* Clinically significant cirrhosis with or without portal hypertension
* Lung infection with organisms associated with a more rapid decline in pulmonary status
* Solid organ or hematological transplantation

Other protocol defined Inclusion/Exclusion criteria may apply
C: Key Inclusion Criteria:

* Completed study drug treatment in parent study (VX18-445-106 Part B, NCT03691779), or had study drug interruption(s) in parent study but completed study visits up to the last scheduled visit of the Treatment Period in the parent study

Key Exclusion Criteria:

* History of study drug intolerance in parent study

Other protocol defined Inclusion/Exclusion criteria may apply
D: Inclusion Criteria:

* Homozygous for F508del-CFTR gene
* Sweat chloride ≥ 60 mEq/L by quantitative pilocarpine iontophoresis
* Body weight ≥ 40 kg
* FEV1 ≥ 40% predicted
* Oxygen saturation ≥ 90% breathing ambient air
* Hematology and clinical chemistry of blood and urine results with no clinically significant abnormalities that would interfere with the study assessments
* Negative pregnancy test for women of child bearing potential
* Sexually active subjects of child bearing potential willing to follow contraception requirements

Exclusion Criteria:

* Previous enrollment in another cohort for this study.
* Any acute infection, including acute upper or lower respiratory infections and pulmonary exacerbations that require treatment within 4 weeks of Study Day 1.
* Any change in chronic therapies for CF lung disease within 4 weeks of Study Day 1.
* Blood hemoglobin \<10 g/dL at screening.
* Serum albumin \<2.5 g/dL at screening.
* Abnormal liver function defined as ≥ 3 x upper limit of normal (ULN) in three or more of the following: AST, ALT, GGT, ALP, total bilirubin at screening.
* History of abnormal renal function (creatinine clearance \< 50 mL/min using Cockcroft-Gault equation) within a year at screening.
* History, including the screening assessment, of ventricular tachycardia or other ventricular arrhythmias.
* History, including the screening assessment, of prolonged QT and/or QTcF interval (\> 450 msec).
* History of solid organ or hematological transplantation.
* Intranasal medication changes within 14 days prior to Study Day 1
* Required Use of continuous (24 hr/d) or nocturnal supplemental oxygen.
* Concomitant use of any inhibitors or inducers of CYP3A4.
