Substantiation In de fase 3 studies genaamd DELOS en SYROS werden positieve effecten gezien met betrekking tot de ademhalingsfunctie van patiënten. Er is op dit moment nog niet te zeggen of het geneesmiddel enige meerwaarde zal hebben. Idebenone heeft een ander werkingsmechanisme dan edasalonexent. Mogelijk zullen deze geneesmiddelen gecombineerd worden bij bewezen effectiviteit.
