This is a multi-center, double-blind, Phase 3 study in up to 60 patients with FCS. Participants will be randomized in a 2:1 ratio to receive Olezarsen or matching placebo in a 53-week treatment period. The length of participation in the study is approximately 74 weeks, which includes an up to 8-week screening period, a 53-week treatment period, and a 13-week post-treatment evaluation period.
