Efficacy Study of Diazoxide Choline to Treat Hypertriglyceridemia

The population will consist of Statin-naive and Statin-treated subjects, all without diabetes mellitus, with fasting triglyceride levels in the range of ≥ 500 mg/dL and < 1500 mg/dL.

Subjects will be randomly assigned to 1 of 2 treatment groups: DCCR and Placebo

Approximately 44 subjects will be enrolled in the study and stratified by Statin use at a 1:1 ratio in each treatment group,

Inclusion criteria
