Title: A Phase 1, Randomized, Double-Blind, Placebo-Controlled, Multiple-Ascending Dose Study Evaluating the Safety, Tolerability, and Pharmacokinetic Effects of N91115 in Healthy Subjects
Brief Summary: A study in healthy subjects to assess the safety, tolerability, and pharmacokinetics of N91115.

* Subject is Caucasian.
* Female subject must be of non-childbearing potential (surgically sterile \[hysterectomy or bilateral tubal ligation\] or post-menopausal ≥ 1 year with follicle stimulating hormone \[FSH\] \> 40 U/L). Women receiving hormone replacement therapy (HRT) are eligible to enroll.
* Male subject must agree to use condoms and refrain from sperm donation from Day 1 until 30 days post last dose or have documentation of vasectomy.
* Subject has a body weight \> 50 kg and body mass index (BMI) between 19.5 and 32 kg/m2, inclusive, at screening.
* Subject has no clinically significant abnormal findings related to their systolic or diastolic blood pressure (BP), per the investigator's judgment, at screening or Day 1.
* Subject has no clinically significant abnormal findings in 12 lead ECG, per the investigator's judgment, at screening.

Exclusion Criteria:

* Subject has clinically significant history or evidence of cardiovascular, respiratory, hepatic, renal, gastrointestinal, endocrine, neurological, immunological, or psychiatric disorder(s) as determined by the investigator or designee.
* Subject has clinically significant abnormalities on a 12 lead ECG done at screening
* Subject has clinically significant abnormalities on a 48-hour ambulatory ECG done at screening
* Subject has any disorder that would interfere with the absorption, distribution, metabolism, or excretion of drugs.
* Subject has any concurrent disease or condition that, in the opinion of the investigator, would make the subject unsuitable for participation in the clinical study.
* Subject is unlikely to comply with the protocol requirements, instructions, and study related restrictions; e.g., uncooperative attitude, unavailable for follow-up call, and/or improbability of completing the clinical study.
B: Key Inclusion Criteria:

* Body weight ≥35 kg.
* Subjects must have an eligibleCFTR genotype.

  * Part 1 and Part 3: Heterozygous for F508del and an MF mutation (F/MF)
  * Part 2: Homozygous for F508del (F/F)
* FEV1 value ≥40% and ≤90% of predicted mean for age, sex, and height

Key Exclusion Criteria:

* History of clinically significant cirrhosis with or without portal hypertension.
* Glucose-6-phosphate dehydrogenase (G6PD) deficiency
* Lung infection with organisms associated with a more rapid decline in pulmonary status.
* History of solid organ or hematological transplantation.

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

* Evidence of signed and dated informed consent/assent document(s) indicating that the subject (and/or his parent/legal guardian) has been informed of all pertinent aspects of the trial
* Age \>=6 years.
* Body weight \>=16 kg.
* Sweat chloride \>60 milliequivalent per liter (mEq/L)
* Documentation of the presence of a nonsense mutation in at least 1 allele of the cystic fibrosis transmembrane conductance regulator (CFTR) gene, as determined by genotyping performed at a laboratory certified by the College of American Pathologists (CAP), or under the Clinical Laboratory Improvement Act/Amendment (CLIA), or by an equivalent organization
* Verification that a blood sample has been drawn for sequencing of the CFTR gene
* Ability to perform a valid, reproducible spirometry test using the study-specific spirometer with demonstration of an FEV1 \>=40% and \<=90% of predicted
* Demonstration at Visit 2 of a valid %-predicted FEV1 within 15% of the Screening % predicted FEV1 value
* Resting oxygen saturation (as measured by pulse oximetry) \>=92% on room air.
* Confirmed screening laboratory values within pre-specified ranges
* In subjects 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, study procedures, laboratory tests, and study restrictions

Exclusion Criteria:

* Known hypersensitivity to any of the ingredients or excipients of the study drug
* Previous participation in the Phase 3 trial of ataluren (PTC124-GD-009-CF).
* Any change (initiation, change in type of drug, dose modification, schedule modification, interruption, discontinuation, or re-initiation) in a chronic treatment/prophylaxis regimen for Cystic Fibrosis (CF) or for CF-related conditions within 4 weeks prior to screening
* Chronic use of inhaled aminoglycosides (eg, tobramycin) or use of inhaled aminoglycosides within 4 weeks prior to screening.
* Exposure to another investigational drug within 4 weeks prior to screening
* Ongoing participation in any other therapeutic clinical trial
* Evidence of pulmonary exacerbation or acute upper or lower respiratory tract infection (including viral illnesses) within 3 weeks prior to screening
* Treatment with intravenous antibiotics within 3 weeks prior to screening
* Ongoing immunosuppressive therapy (other than corticosteroids)
* Ongoing warfarin, phenytoin, or tolbutamide therapy
* History of solid organ or hematological transplantation
* Major complications of lung disease (including massive hemoptysis, pneumothorax, or pleural effusion) within 8 weeks prior to screening
* Known portal hypertension
* Positive hepatitis B surface antigen, hepatitis C antibody test, or human immunodeficiency virus (HIV) test
* Pregnancy or breast-feeding
* Current smoker or a smoking history of \>=10 pack-years (number of cigarette packs/day x number of years smoked).
* Prior or ongoing medical condition (eg, concomitant illness, alcoholism, drug abuse, psychiatric condition), medical history, physical findings, electrocardiogram (ECG) findings, or laboratory abnormality that, in the investigator's opinion, could adversely affect the safety of the subject, makes it unlikely that the course of treatment or follow-up would be completed, or could impair the assessment of study results
D: Inclusion Criteria:

* Confirmed diagnosis of CF
* Homozygous for the F508del CFTR mutation
