  Treatment-naïve Group

  Treatment naïve group included combined group of ISIS 304801-CS7 (CS7-New) study participant and participant on placebo in index studies (ISIS 304801-CS6 \[NCT02211209\] and ISIS 304801-CS16 \[NCT02300233\]), were to receive 300 mg of volanesorsen as single SC once weekly for Weeks 1-52 of this study. Participants were allowed dose adjustment/dose reduction based on monitoring rules. Following Week 52 visit, participants had option of participating in expanded access program or continuing treatment with 300 mg of volanesorsen as single SC once-weekly for up to additional 52 weeks (Weeks 53-104) and in France participants, up to additional 104 weeks for total of 156 weeks (Weeks 105 to Week 156) until expanded access program was approved and available in their country. Participants who were not participating in expanded access program were to enter 13-week post-treatment (PT) evaluation period and in France, participants not continuing treatment were to enter 26-week PT follow-up period.

  Drug: Volanesorsen

• Experimental
  CS6-Volanesorsen

  Participants with FCS rolling over from the ISIS 304801-CS6 (NCT02211209) index study after receiving volanesorsen, were to receive 300 mg of volanesorsen as a single SC injection once weekly for Weeks 1-52 of this study. Participants were allowed dose adjustment/dose reduction based on monitoring rules. Following the Week 52 visit, participants had the option of participating in an expanded access program or continuing treatment with 300 mg of volanesorsen as a single SC injection once-weekly for up to an additional 52 weeks (Weeks 53-104) and in France participants, up to an additional 104 weeks for total of 156 weeks of treatment (Weeks 105 to Week 156) of this study 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 post-treatment evaluation period and in France, participants not continuing treatment were to enter a 26-week post-treatment follow-up period.

  Drug: Volanesorsen

• Experimental
  CS16-Volanesorsen

  Participants with FCS rolling over from the ISIS 304801-CS16 (NCT02300233) index study after receiving volanesorsen, were to receive 300 mg of volanesorsen as a single SC injection once weekly for Weeks 1-52 of this study. Participants were allowed dose adjustment/dose reduction based on monitoring rules. Following the Week 52 visit, participants had the option of participating in an expanded access program or continuing treatment with 300 mg of volanesorsen as a single SC injection once-weekly for up to an additional 52 weeks (Weeks 53-104) and in France participants, up to an additional 104 weeks for total of 156 weeks of treatment (Weeks 105 to Week 156) of this study 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 post-treatment evaluation period and in France, participants not continuing treatment were to enter a 26-week post-treatment follow-up period.

Primary outcomes

1. Mean Percent Change From Baseline in Fasting Triglyceride (TG)

   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.

   Time frame: Baseline and Months 3, 6, and 12

2. Number of Participants With Treatment-emergent Adverse Events (TEAEs)

   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.

   Time frame: From first dose of study drug to end of follow-up period [Up to Week 182]
