Subjects will take ataluren for approximately 96 weeks, 3 times per day:

- and evening 20 mg/kg
Study assessments will be performed at clinic visits:

- on the first day of ataluren dosing
- and then every 12 weeks during the ataluren treatment period
Primary Objective: to assess the long-term safety and tolerability of the stated doses.
Secondary objectives include the following:
- To determine the effect of ataluren on ambulation and other aspects of physical function in ambulatory patients*
- To assess the effect of ataluren on daily activities, upper limb function, and breathing in non-ambulatory patients**
- To assess patient and/or parent/caregiver reports of changes in disease status:
