Effects of Prescription Omega-3 Acids on Glucose and Lipoprotein Lipids in Subjects With Hypertriglyceridemia

The objectives of this study are to assess the effects of 4 g/d prescription omega-3 acid ethyl esters (POM3), compared with a placebo, on indices of insulin sensitivity and secretion, as well as aspects of the fasting and postprandial lipid and lipoprotein profiles, in subjects with hypertriglyceridemia.

About this study

This trial will utilize a randomized, double-blind, two-period crossover design. At Visit 2 (Week 0), subjects meeting all entry criteria will be randomized to one of two treatment sequences: placebo or POM3 for the first 6 week phase followed by the study product they did not receive during the first phase (POM3 or placebo) for the second 6 weeks. There will be a 2-week washout period between treatment phases.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Men and postmenopausal women, ages 18-79 years.
  • Fasting, triglyceride (TG) level in the borderline high to high range.
  • Fasting, low density lipoprotein cholesterol (LDL-C) below the very high range while on no lipid altering therapy or while taking stable-dose statin therapy
  • Provide written informed consent and authorization for protected health information

Exclusion criteria

  • Use of any lipid-altering medications, which cannot be stopped, except stable dose statin therapy.
  • Use of any omega-3 fatty acid ethyl ester medications or dietary supplements with >1.0 g/d of eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), or a combination of EPA and DHA
  • coronary heart disease (CHD) or a CHD risk equivalent
  • Body mass index over 45 kg per square meter
  • Allergy or sensitivity to omega-3 fatty acids, corn or corn products (e.g., corn oil), D-alpha tocopherol (vitamin E) or any ingredients in the study drug
  • Certain muscle, liver, kidney, lung or gastrointestinal conditions
  • Poorly controlled hypertension
  • Certain medications
  • Active cancers treated within prior 2 years (except non-melanoma skin cancer)

Treatment and study plan

POM3

Drug

4 g/day

Other names: Lovaza, prescription omega-3 acid ethyl esters

Placebo

Drug

matching placebo capsule, 4 g/day

Primary outcomes

  1. Difference Between Treatments in Liquid Meal Tolerance Test (LMTT) Matsuda Insulin Sensitivity Index (MISI).

    Time frame: End of Treatment Intervention Period I (week 6) and End of Treatment Intervention Period II (week 14)

    Liquid meal tolerance test (LMTT) = two 8 oz servings of Ensure (Abbott Nutrition) + study product followed by blood sample collection at -5, -1, 30, 60, 90, 120, 180, and 240 min, where t = 0 was start of liquid meal consumption. MISI calculated as 10,000/square root of (pre-meal glucose x pre-meal insulin x mean 120 min post-meal glucose x mean 120 min post-meal insulin)

Secondary outcomes

  1. Difference Between Treatments in LMTT Insulin Secretion Index and Disposition Index.

    Time frame: End of Treatment Intervention Period I (week 6) and End of Treatment Intervention Period II (week 14)

    Insulin secretion index = total area under the curve from 0 to 120 min post-meal for plasma insulin divided by total area under the curve from 0 to 120 min post-meal for plasma glucose.

    Disposition index = MISI x insulin secretion index
