Title: An Open-Label Safety and Efficacy Study for Patients With Nonsense Mutation Cystic Fibrosis Previously Treated With Ataluren (PTC124)
Brief Summary: The primary objective of this study is to determine the long-term safety and tolerability of ataluren in participants with nonsense mutation cystic fibrosis (nmCF) who completed participation in the double-blind study PTC124-GD-009-CF (NCT00803205), as assessed by adverse events and laboratory abnormalities. The secondary objective of this study includes the assessment of the efficacy of ataluren, as measured by forced expiratory volume in 1 second (FEV1) and pulmonary exacerbation rate, and other safety parameters (for example, 12-lead electrocardiogram \[ECG\] measurements, vital signs).


Options:
A: Key Inclusion Criteria:

* Ability to provide written informed consent (parental/guardian consent and participant assent if less than \[\<\] 18 years of age).
* Evidence of completed participation in the double-blind study, PTC124-GD-009-CF (Study 009).
* Body weight greater than or equal to (≥) 16 kilograms (kg).
* Performance of a valid, reproducible spirometry test using the study-specific spirometer during the screening period.
* Confirmed laboratory values within the central laboratory ranges at screening.
* In male and female participants who are sexually active, willingness to abstain from sexual intercourse or employ a barrier or medical method of contraception during the study drug administration and 60-day follow-up period.
* Willingness and ability to comply with all study procedures and assessments, including scheduled visits, drug administration plan, laboratory tests, and study restrictions.

Key Exclusion Criteria:

* Chronic use of systemic tobramycin within 4 weeks prior to screening.
* Evidence of pulmonary exacerbation or acute upper or lower respiratory tract infection (including viral illnesses) within 3 weeks prior to screening or between screening and randomization.
* Any change (initiation, change in type of drug, dose modification, schedule modification, interruption, discontinuation, or re-initiation) in a chronic treatment/prophylaxis regimen for CF or for CF-related conditions within 4 weeks prior to screening and randomization.
* Known hypersensitivity to any of the ingredients or excipients of the study drug.
* Exposure to another investigational drug within 4 weeks prior to screening.
* Treatment with intravenous antibiotics within 3 weeks prior to screening.
* History of solid organ or hematological transplantation.
* Ongoing immunosuppressive therapy (other than corticosteroids).
* Positive hepatitis B surface antigen, hepatitis C antibody test or human immunodeficiency virus (HIV) test.
* Known portal hypertension.
* Pregnancy or breast-feeding.
B: 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
C: Inclusion Criteria:

* Homozygous for the F508del-CFTR mutation
* Confirmed diagnosis of CF defined as a sweat chloride value ≥60 mmol/L by quantitative pilocarpine iontophoresis
* 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
D: Inclusion Criteria:

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.
