简要总结
This is an open-label extension study for participants who completed a Phase 3, placebo-controlled study of ataluren in participants with nonsense mutation cystic fibrosis (nmCF) not receiving chronic inhaled aminoglycosides.
详细描述
The primary objective of this Phase 3 extension study will be to obtain long-term safety data to augment the overall safety database. The secondary objectives will be to augment the efficacy data collected in the double-blind study (PTC124-GD-021-CF; NCT02139306).

研究组 & 干预措施
Ataluren
Participants will be administered ataluren orally at a dose of 10 milligrams/grams (mg/kg) in the morning, 10 mg/kg at midday, and 20 mg/kg in the evening for up to 96 weeks.
干预措施: Ataluren (Drug)
结局指标
主要结局
Number of Participants With a Clinically Meaningful Abnormal Clinical Laboratory (Serum Biochemistry, Hematology, and Urinalysis) Parameter
时间窗: Baseline up to Week 100
Clinical laboratory results considered clinically meaningful were determined by Investigator. Serum biochemistry parameters: sodium, potassium, chloride, bicarbonate, blood urea nitrogen, creatinine, magnesium, calcium, phosphorus, uric acid, glucose, total protein, albumin, globulin, bilirubin, creatine kinase, lactate dehydrogenase, alanine aminotransferase, aspartate aminotransferase, gamma glutamyl transferase, alkaline phosphatase, total cholesterol, high-density lipoprotein, low-density lipoprotein, triglycerides, and cystatin C. Hematology parameters: white blood cell count, hemoglobin, hematocrit, mean corpuscular volume, mean corpuscular hemoglobin, red cell count with morphology, and platelet count. Urinalysis parameters: pH, specific gravity, glucose, ketones, blood, protein, creatinine, urobilinogen, bilirubin, nitrite, and leukocyte esterase. A summary of all SAEs/nonserious AEs, regardless of causality, is located in the Reported Adverse Events section.
Number of Participants With Treatment Emergent Adverse Events (TEAEs)
时间窗: Baseline up to Week 100
TEAE: any untoward medical occurrence or undesirable event that begins or worsens following administration of study drug, whether or not considered related to study drug by Investigator. Serious adverse event (SAE): an adverse event (AE) resulting in any of following outcomes or deemed significant for any other reason: death, initial or prolonged inpatient hospitalization, life-threatening experience (immediate risk of dying) or persistent or significant disability/incapacity. Except for cystic fibrosis (CF) pulmonary exacerbations, an event wasn't reported as an SAE, if event was exclusively a relapse or an expected change or progression of baseline CF. AEs included both SAEs and nonserious AEs. AEs classified according to National Cancer Institute Common Terminology Criteria for Adverse Events version 3.0 and coded using Medical Dictionary for Regulatory Activities. A summary of SAEs and all nonserious AEs, regardless of causality, is located in the Reported Adverse Events section.
次要结局
- Rate of Pulmonary Exacerbations as Defined by Modified Fuch's Criteria Over 48 Weeks(Baseline up to Week 48)
- Change From Baseline in Percent-Predicted Forced Expiratory Volume in 1 Second (FEV1) as Measured by Spirometry at Week 24(Baseline, Week 24)
- Change From Baseline in Percent-Predicted of Forced Vital Capacity (FVC) as Measured by Spirometry at Week 24(Baseline, Week 24)
- Change From Baseline in Forced Expiratory Flow Between 25% and 75% of Expiration (FEF25-75) as Measured by Spirometry at Week 24(Baseline, Week 24)
