Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Absolute Change From Baseline to Month 3 in Fasting Triglycerides (TG)	Baseline was defined as the average of Day 1 predose fasting assessment and the last fasting measurement prior to Day 1 pre-dose fasting assessment. Month 3 was defined as the average of Week 13 and Week 14 fasting assessments.	Baseline to Month 3
Primary	Percent Change From Baseline to Month 3 in Fasting Triglycerides (TG)	Baseline was defined as the average of Day 1 predose fasting assessment and the last fasting measurement prior to Day 1 pre-dose fasting assessment. Month 3 was defined as the average of Week 13 and Week 14 fasting assessments.	Baseline to Month 3
Secondary	Absolute Change From Baseline to Month 3 in Fasting Angiopoietin-Like 3 (ANGPTL3)	Baseline was defined as the average of Day 1 predose fasting assessment and the last fasting measurement prior to Day 1 pre-dose fasting assessment. Month 3 was defined as the average of Week 13 and Week 14 fasting assessments.	Baseline to Month 3
Secondary	Percent Change From Baseline to Month 3 in Fasting Angiopoietin-like 3 (ANGPTL3)	Baseline was defined as the average of Day 1 predose fasting assessment and the last fasting measurement prior to Day 1 pre-dose fasting assessment. Month 3 was defined as the average of Week 13 and Week 14 fasting assessments.	Baseline to Month 3
Secondary	Fasting Lipid and Lipoprotein Measurements at Month 3	Fasting lipid and lipoprotein measurements included non-HDL-C, ApoB, HDL-C, ApoA-1, VLDL-C and LDL-C. Month 3 was defined as the average of Week 13 and Week 14 fasting assessments.	Month 3
Secondary	Absolute Change From Baseline to Month 3 in Other Fasting Lipid Parameters	Other fasting lipid measurements included total cholesterol (TC), non-HDL-C, ApoB, HDL-C, ApoA-1, VLDL-C, and LDL-C. Baseline was defined as average of Day 1 predose fasting assessment and last fasting measurement prior to Day 1 pre-dose fasting assessment. Month 3 was defined as the average of Week 13 and Week 14 fasting assessments.	Baseline to Month 3
Secondary	Percent (%) Change From Baseline to Month 3 in Other Fasting Lipid Parameters	Other fasting lipid measurements included TC, non-HDL-C, ApoB, HDL-C, ApoA-1, VLDL-C, and LDL-C. Baseline was defined as average of Day 1 predose fasting assessment and last fasting measurement prior to Day 1 pre-dose fasting assessment. Month 3 was defined as the average of Week 13 and Week 14 fasting assessments.	Baseline to Month 3
Secondary	Change From Baseline to Day 92 in Maximum Postprandial Triglycerides (TG)	Participants consumed standardized pre-cooked meals (lunches and dinners and instructions for breakfasts and snacks) for 2 days prior to the postprandial assessments. Change from Baseline to Day 92 in maximum postprandial TG was assessed.	Baseline to Day 92
Secondary	Number of Participants Who Experienced Abdominal Pain During the Treatment Period		Days 1, 29, 57 and 92
Secondary	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, for example), symptom, or disease temporally associated with the study or use of investigational drug product, whether or not the AE is considered related to the investigational drug product. A TEAE was defined as any AE starting on or after the first dose of the study drug.	From time of informed consent to end of follow-up period (Up to Week 26)
