Detailed Description
This is a Phase 3, multi-center, open-label safety study of up to 30 participants with FCS, previously treated with volanesorsen. The study consists of 3 periods: 1) Screening Period: Week -8 to Week -1 (up to 8 weeks); 2) Treatment Period up to Week 157; and 3) Post-Treatment Follow-up Period: Week 158 to Week 170 (12 weeks). Participants enrolled will receive olezarsen every 4 weeks during the 157-week Treatment Period.
This study was extended to allow participants to receive olezarsen for an additional 104 weeks following the initial 53-week treatment period.

Description
Inclusion Criteria
Participants with FCS (clinical or genetic diagnosis) currently on or previously treated with volanesorsen (ISIS 304801)
o Study participants in countries where Waylivra® is commercially approved and available for participants should not be deprived of the treatment option with Waylivra®. Participation in this study for such participants will only be allowed when Waylivra® was discontinued due to AEs
The following concomitant medications will be allowed if dosing regimen is expected to remain constant through the end of the study (occasional or intermittent use of over-the-counter (OTC) medications will be allowed at Investigator's discretion):
- Statins, omega-3 fatty acids (prescription and OTC), fibrates, or other lipid-lowering medications. Participants taking OTC omega-3 fatty acids should make every effort to remain on the same brand through the end of the study
- Antidiabetic medications
- Oral anticoagulants (e.g., dabigatran, rivaroxaban, or apixaban, and warfarin with regular clinical monitoring)
- Tamoxifen, estrogens or progestins
Exclusion Criteria:
- Treatment with another investigational drug (non-oligonucleotide), biological agent, or device within 4 weeks of Screening, or 5 half-lives of investigational agent, whichever is longer
Concomitant medication/procedure restrictions:
- Systemic corticosteroids or anabolic steroids within 6 weeks prior to Screening and during the study unless approved by the Sponsor Medical Monitor
- Plasma apheresis within 4 weeks prior to Screening or planned during the study
