What researchers measure

Primary outcomes

  1. Percent Change in Fasting Triglycerides (TG) From Baseline to Month 3

    Time frame: Baseline to 3 months

Secondary outcomes

  1. Absolute Change in Fasting TG From Baseline to Month 3

    Time frame: Baseline to 3 months

  2. Treatment Response Rate Defined as Participants With Fasting TG ≥ 40% Reduction From Baseline at Month 3

    Time frame: Baseline to 3 months

  3. Percent Change in High-density Lipoprotein-cholesterol (HDL-C) From Baseline

    Time frame: Baseline to 3 months

  4. Treatment Response Rate Defined as Participants With Fasting TG < 150 mg/dL Reduction From Baseline at Month 3

    mg/dL = milligrams per deciliter

    Time frame: Baseline to 3 months

  5. Change From Baseline in Homeostasis Model Assessment-estimated Insulin Resistance (HOMA-IR)

    HOMA-IR was calculated using the following formula: fasting insulin micro-international units per millimeter (μIU/mL) x fasting glucose mg/dL\]/405. A negative change from baseline indicates improvement; a positive change from baseline indicates worsening.

    Time frame: Baseline to 3 and 6 months

  6. Change From Baseline in Glycated Hemoglobin (HbA1c) in Type 2 Diabetes Mellitus (T2DM) Participants

    Time frame: Baseline to 3 and 6 months
