Official title

A Phase 3 Efficacy and Safety Study of PTC124 as an Oral Treatment for Nonsense-Mutation-Mediated Cystic Fibrosis

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

Cystic fibrosis (CF) is a genetic disorder caused by a mutation in the gene that makes the cystic fibrosis transmembrane conductance regulator (CFTR) protein. A specific type of mutation called a nonsense (premature stop codon) mutation is the cause of CF in approximately 10% of patients with the disease. Ataluren is an orally delivered investigational drug that has the potential to overcome the effects of the nonsense mutation. This study is a Phase 3 trial that will evaluate the clinical benefit of ataluren in adult and pediatric participants with CF due to a nonsense mutation. The main goals of the study are to understand whether ataluren can improve pulmonary function and whether the drug can safely be given for a long period of time. The study will also assess the effects of ataluren on CF pulmonary exacerbation frequency, cough frequency, health-related quality of life, antibiotic use for CF-related infections, CF-related disruptions to daily living, body weight, and CF pathophysiology.
