Study Stopped
The trial was stopped to reduce the clinical trial burden on participants while ensuring continued treatment via a post-trial access program with commercially available casimersen and golodirsen. Study was not terminated due to safety concerns.

Outcome Measures
Primary Outcomes (1)
Number of Participants With Treatment-emergent Serious Adverse Events (TESAEs)
A treatment-emergent adverse event (TEAE) was any untoward medical occurrence in a clinical study participant that did not necessarily have a causal relationship with the study drug. A TEAE could, therefore, be any unfavorable and unintended symptom, sign, disease, condition, or test abnormality that occurred during or after administration of the study drug, whether or not considered related to the study drug. A TESAE was any TEAE that resulted in any of the following outcomes: death, a life-threatening event, required or prolonged inpatient hospitalization, persistent or significant disability/incapacity, or an important medical event (that is, may have jeopardized the participant and may have required medical or surgical intervention to prevent one of the previously mentioned outcomes). A summary of serious and all other non-serious TEAEs regardless of causality is located in the Reported Adverse Events module.
Up to 33 days after the last infusion of study drug (up to approximately 149 weeks)
