symptom onset will be defined as the date the subject first had symptoms of their
disease, i.e., weakness. To be eligible for this study, the date of symptom onset must
be no greater than exactly 9 months prior to the Screening Visit date.

- Bilirubin >1.5 × ULN unless the participant has documented Gilbert syndrome
(isolated bilirubin >1.5 × ULN is acceptable if bilirubin is fractionated and
direct bilirubin is <35%)
