4. Fasting triglyceride <4.52 mmol/L (<400 mg/dL) at screening.
5. Participants on statins should be receiving a maximally tolerated dose.
6. Participants not receiving statins must have documented evidence of intolerance to all doses of at least 2 different statins.
7. Subjects on lipid-lower therapies (such as a statin and/or ezetimibe) should be on a stable dose for ≥30 days before screening with no planned medication or dose change during study participation.

Exemptions from this criterion:

   1. Women >2 years postmenopausal (defined as 1 year or longer since last menstrual period) and more than 55 years of age.
