The trial’s primary endpoint was to measure the change in the North Star Ambulatory Assessment (NSAA) over one year of edasalonexent treatment, compared to a placebo. The secondary endpoints were the timed function test (time to stand, 10-meter walk/run, and 4-stair climb) did not show statistically significant improvements. Muscle enzymes and heart rate did not show significant differences between edasalonexent and placebo.

Edasalonexent was well-tolerated, which is consistent with the safety profile that is seen to date. The majority of adverse events were mild in nature, and the most common treatment-related adverse events were diarrhea, vomiting, abdominal pain and rash. There were no treatment-related serious adverse events and no dose reductions. There were no adverse trends in blood tests and growth was maintained.
