Study Endpoints
Primary Endpoints
Percent Change From Baseline in Fasting Triglycerides (TG) at the Primary Analysis Time Point
Baseline and Month 6 (Week 25 for Cohorts A and B and Week 27 for Cohorts C and D)

An analysis of covariance (ANCOVA) model was performed on the log ratio of TG value at the Primary Analysis Time Point to TG value at Baseline. The estimate of the log ratio was converted back to the original scale and percent change was calculated using formula: (ratio of TG value at the Primary Analysis Time Point to TG value at Baseline - 1) × 100.

Number of Participants With Treatment-Emergent Adverse Events (TEAEs)
Up to the 13-week post-treatment follow-up period (Up to approximately 15 months)

An adverse event (AE) was defined as any unfavorable and unintended sign (including a clinically-significant abnormal laboratory finding, for example), symptom, or disease temporally associated with the study or use of investigational drug product, whether or not the AE was considered to be related to the investigational drug product. A TEAE was defined as any AE starting on or after the first dose of the study drug.

Secondary Endpoints
Percent Change From Baseline in ApoC-III, TC, LDL-C, HDL-C, Non-HDL-C, VLDL-C, ApoB, and ApoA-I at the Primary Analysis Time Point
Baseline and Month 6 (Week 25 for Cohorts A and B and Week 27 for Cohorts C and D)
Percentage of Participants Who Achieved Fasting Triglycerides (TG) <= 150 mg/dL (<= 1.7 Millimoles Per Liter [mmol/L])
Baseline and Month 6 (Week 25 for Cohorts A and B and Week 27 for Cohorts C and D)
Percentage of Participants Who Achieved Fasting Triglycerides (TG) <= 100 mg/dL (<= 1.13 mmol/L)
