This study was a multicenter, open-label study in up to 168 participants, who were randomized to receive subcutaneous (SC) injections of either eplontersen once every 4 weeks or inotersen once a week. Participants also received daily supplemental doses of the recommended daily allowance of vitamin A. Participants included in the inotersen reference arm crossed over to eplontersen at Week 37 after completing the Week 35 assessments.
