| Primary | DB Period: Change From Baseline in 6-Minute Walk Distance (6MWD) at Week 72 - Modified Intention-to-treat (mITT) Population | Baseline, Week 72 | The 6MWD test is a non-encouraged test performed in a 30 meters long flat corridor, where the participant is instructed to walk as far as possible, back and forth around two cones, with the permission to slow down, rest, or stop if needed. Ambulation was assessed via the 6MWD test following standardized procedures. Participants were not permitted to use assistive devices (walker, long leg braces, or short leg braces) during the 6MWD test. Participants with confirmed loss of ambulation at a particular visit were assigned a 6MWD result of 0. Baseline was defined as the maximum measurement of valid Day 1 and Day 2 6MWD values. Least square (LS) mean and standard error (SE) was calculated using the mixed-model repeated measures (MMRM). |

| Secondary | DB Period: Time to Persistent 10% Worsening in 6MWD at Week 72 - mITT Population | Baseline to Week 72 | The 6MWD test is a non-encouraged test performed in a 30 meters long flat corridor, where the participant is instructed to walk as far as possible, back and forth around two cones, with the permission to slow down, rest, or stop if needed. Ambulation was assessed via the 6MWD test following standardized procedures. Participants were not permitted to use assistive devices (walker, long leg braces, or short leg braces) during the 6MWD test. Time to 10% persistent worsening in 6MWD was defined as the last time that 6MWD was not 10% worse compared with baseline. Participants who did not have 10% 6MWD worsening were censored at the time of the last 6-minute walk test during the DB period. |
| Secondary | DB Period: Time to Persistent 10% Worsening in 6MWD - ITT Population | Baseline to approximately Week 72 (Due to COVID, many participants attended the protocol-defined Week 72 visit late) | 6MWD test is a non-encouraged test performed in a 30 meters long flat corridor, where participant is instructed to walk as far as possible, back and forth around two cones, with permission to slow down, rest, or stop if needed. Ambulation was assessed via 6MWD test following standardized procedures. Participants were not permitted to use assistive devices (walker, long leg braces, or short leg braces) during 6MWD test. Time to 10% persistent worsening in 6MWD was defined as the last time that 6MWD was not 10% worse compared with baseline. Participants who did not have 10% 6MWD worsening were censored at the time of last 6-minute walk test during DB period. Due to COVID, there were many participants who participated in the protocol-defined Week 72 visit late. Due to this reason, the calculated median for the time to event for the Ataluren arm in the DB period were greater than Week 72. |
| Secondary | DB Period: Change From Baseline in North Start Ambulatory Assessment (NSAA) Total Score at Week 72 - mITT Population | Baseline, Week 72 | The NSAA total score in the original scale is the sum of scores from 16 activities (excluding head lift). Each activity was scored as 0 (activity couldn't be performed), 1 (modified method, achieved goal without assistance), or 2 (normal, achieved goal without assistance). The total score ranges from 0 to 32, where higher scores indicate better functioning. If fewer than 13 of the 16 activities were performed, the total score was considered missing. If from 13 to 16 activities were performed, the total score was standardized by (observed total score / number of non-missing activities) x 16. If an activity could not be performed due to disease progression, a score of 0 was assigned. Baseline was defined as the last observed measurement on or prior to the first dose of study drug. LS mean and SE was calculated using the MMRM. |

| Secondary | DB Period: Time to Loss of Ambulation - mITT Population | Baseline up to approximately Week 72 (Due to COVID, many participants attended the protocol-defined Week 72 visit late) | Time to loss of ambulation was defined as persistent inability to perform the 10-meter run/walk test within 30 seconds at any post-baseline visit and for all remaining visits. Due to COVID, there were many participants who participated in the protocol-defined Week 72 visit late. Due to this reason, the calculated median and 95% CI for the time to event for the Ataluren arm in the DB period were greater than Week 72. |
| Secondary | DB Period: Time to Loss of Ambulation Over 72 Weeks - ITT Population | Baseline up to Week 72 | Time to loss of ambulation was defined as persistent inability to perform the 10-meter run/walk test within 30 seconds at any post-baseline visit and for all remaining visits. |
