According to the results reported on ClinicalTrials.gov, this trial (NCT00847379) enrolled 173 participants across three groups who received the study drug ataluren at different doses, or a placebo followed by ataluren. Specifically, 59 participants were in the high-dose ataluren group throughout, 57 were in the low-dose ataluren group (then switched to high-dose), and 57 started on placebo before switching to high-dose ataluren. The trial was primarily measuring whether participants experienced any unwanted medical events (called adverse events) or abnormal results on blood and urine tests during the study period. The reported data shows that across all 173 participants, 149 experienced at least one treatment-emergent adverse event (meaning an unwanted medical occurrence during or shortly after the study period). When broken down by group, this was 52 out of 59 in the high-dose group, 49 out of 57 in the low-dose group, and 48 out of 57 in the placebo-then-high-dose group. Serious adverse events were reported in 10, 10, and 22 participants in those same groups respectively, with 3 participants across all groups experiencing events that were considered possibly related to the study drug. No participants in any group were reported to have clinically significant abnormal laboratory results, according to the investigators' judgement. The reported data also shows results from a walking test (where participants walked as far as they could in 6 minutes) and ankle-worn step counters measured over 60 weeks. All three groups showed a decrease from their starting distance in the 6-minute walking test by week 60 — the high-dose group's average distance fell by about 17 metres, the low-dose group by about 11 metres, and the placebo-then-high-dose group by about 7 metres. Similarly, the step-counting data generally showed small decreases in daily step counts across all groups by week 60, though the specific numbers varied between groups.
