Study of Ataluren in ≥2 to <5 Year-Old Male Participants With Duchenne Muscular Dystrophy

Duchenne Muscular Dystrophy Clinical Trial

Official title: A Phase 2 Study of the Safety, Pharmacokinetics, and Pharmacodynamics of Ataluren (PTC124®) in Patients Aged ≥2 to <5 Years Old With Nonsense Mutation Dystrophinopathy

Status Completed

Clinical Trial Summary

This is a Phase 2, multiple-dose, open-label study evaluating the safety, pharmacokinetics (PK), and pharmacodynamics (PD) of ataluren in participants aged ≥2 to <5 years old with Duchenne muscular dystrophy (DMD) caused by a nonsense mutation in the dystrophin gene.

Clinical Trial Description

In nonsense mutation DMD (nmDMD), early start of treatment is important and necessary and, therefore, it is relevant to understand the correct and tolerable dose in this age group, particularly since ataluren is dosed by weight. This study included a 4-week screening period, a 52-week treatment period (the first 4 weeks of which included PK parameters), and a 4-week follow-up period for participants who completed the treatment period (60 weeks total duration). The objective of the extension period (treatment period after PK parameters have been completed) was to assess the long-term safety of chronic administration of ataluren in this participant population. ;
