Primary	Percent Change From Baseline in Maximum Reading Speed of Oculus Unitas (OU) (Both Eyes) at Week 48, as Measured Using the Minnesota Low Vision Reading Test (MNREAD) Acuity Charts	Baseline, Week 48	MNREAD Acuity Chart can only be used to assess participants ≥8 years old. MNREAD Acuity Chart measures reading speed as a function of print size in participants with normal and low vision. The test consists of short sentences with print size decreasing by 0.1 log unit steps from a maximum of 1.3 logarithm of the minimum angle of resolution (logMAR) (equivalent to 20/400 or 6/120 when viewed at 40 centimeters \[cm\]) to -0.5 logMAR (equivalent to 20/6 or 6/2). An MNREAD Acuity Chart curve of reading speed vs print size has a typical shape for normally sighted persons and many low-vision individuals. This curve is characterized by 3 summary values. At large print sizes, reading speed remains fairly constant, forming a plateau that represents the maximum reading speed. As the print size decreases, a critical print size (CPS) is reached at which reading speed begins to decline rapidly. Finally, the smallest print size that can be read is defined as the reading acuity (RA).
Secondary	Change From Baseline in Reading Accessibility Index of Both Eyes at Week 48	Baseline, Week 48	Reading Accessibility Index is defined as the mean reading speed in words per minute (wpm) across the 10 largest physical print sizes on the MNREAD Acuity Chart, normalized by the value for a group of normally sighted young adults. For a viewing distance of 40 cm, this range of print sizes corresponds to 0.4 to 1.3 logMAR. This range of print sizes was chosen for 2 reasons. First, it sustains the manifest refraction spherical equivalent (MRS) in normally sighted persons. Second, it covers most contemporary printed text found in everyday life. Because the Reading Accessibility Index is normalized by the value for a group of normally sighted young adults (aged 18 to 39 years), a Reading Accessibility Index of 1.0 represents normal performance for this age group. Values less than 1.0 mean reduced accessibility to printed text within the range of print size encountered in daily life. Missing data was imputed using last observation carried forward (LOCF) method.
Secondary	Change From Baseline in Best Corrected Visual Acuity (BCVA) at Week 48	Baseline, Week 48	The BCVA was evaluated using the Early Treatment Diabetic Retinopathy Study (ETDRS) Method. Missing data was imputed using LOCF method.
Secondary	Percent Change From Baseline in Maximum Reading Speed of Oculus Dexter (OD) (Right Eye) and Oculus Sinister (OS) (Left Eye) at Week 48	Baseline, Week 48	Maximum Reading Speed was measured using the MNREAD Acuity Chart, which can only be used to assess participants ≥8 years old. The MNREAD Acuity Chart measures reading speed as a function of print size in participants with normal and low vision. The test consists of short sentences with print size decreasing by 0.1 log unit steps from a maximum of 1.3 logMAR (equivalent to 20/400 or 6/120 when viewed at 40 cm) to -0.5 logMAR (equivalent to 20/6 or 6/2).

Secondary	Change From Baseline in Reading Accessibility Index of Right Eye and Left Eye at Week 48	Baseline, Week 48	Reading Accessibility Index is defined as the mean reading speed in wpm across the 10 largest physical print sizes on the MNREAD Acuity Chart, normalized by the value for a group of normally sighted young adults.

Secondary	Number of Participants With Change From Baseline in Severity of Corneal Keratopathy at Week 48	Baseline to Week 48	The severity of corneal keratopathy was reported as worsened, not change, or improve. Missing data were imputed using LOCF.
Secondary	Change From Baseline in Iris Area at Week 48	Baseline, Week 48	Missing data were imputed using LOCF.
Secondary	Change From Baseline in BCVA at Week 240	Baseline, Week 240	The BCVA was evaluated using the ETDRS Method. Missing data were imputed using LOCF method.
Secondary	Number of Participants With Treatment-Emergent Adverse Events (TEAEs)	Baseline up to Week 244	An adverse event (AE) was any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. AEs included both SAEs and non-serious AEs. A summary of other non-serious AEs and all SAEs, regardless of causality is located in the 'Reported AE section'. AEs were summarized separately for Stage 1 and for the overall ataluren experience, which included all participants who received ataluren throughput the study (Stage 1, open-label extension period \[Stage 2\], and sub-study).
