Detailed Description

This is a multi-center, open-label study for FCS participants rolling over from the ISIS 304801-CS6 (NCT02211209) index study, FCS participants rolling over from the ISIS 304801-CS16 (NCT02300233) index study and Treatment-naïve group. All participants were to receive volanesorsen 300 milligrams (mg) once per week for 52 weeks. Participants were allowed dose adjustment/dose reduction based on monitoring rules. Participants had the option of continuing dosing for an additional 52 weeks (France: up to an additional 104 weeks for a total of 156 weeks) until an expanded access program was approved and available in their country. Participants who were not participating in an expanded access program were to enter a 13-week (France: 26-week) post-treatment evaluation period.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Mean Percent Change From Baseline in Fasting Triglyceride (TG)
Time Frame: Baseline and Months 3, 6, and 12
Baseline for treatment-naïve group was defined as the average of open-label Day 1 pre-dose assessment and the last measurement prior to open-label Day 1. Baseline for CS6-volanesorsen and CS16-volanesorsen arm groups was defined as the average of index study Day 1 pre-dose assessment and the last measurement prior index study Day 1. The values at the Month 3 analysis time point were defined as the average of the Week 12 (Day 78) and Week 13 (Day 85) fasting assessments. The Month 6 analysis time point was at the end of Month 6, and the values were defined as the average of the Week 25 (Day 169) and Week 26 (Day 176) fasting assessments. The values at the Month 12 analysis time point were defined as the average of the Week 50 (Day 344) and Week 52 (Day 358) fasting assessments.
Baseline and Months 3, 6, and 12
Number of Participants With Treatment-emergent Adverse Events (TEAEs)
Time Frame: From first dose of study drug to end of follow-up period [Up to Week 182]
An adverse event (AE) was defined as any unfavorable and unintended sign (including a clinically significant abnormal laboratory finding), symptom, or disease temporally associated with the study or use of investigational drug product, whether or not the AE was considered related to the investigational drug product. A TEAE was defined as any AE starting or getting worse on or after the first dose of the study drug.
From first dose of study drug to end of follow-up period [Up to Week 182]
