Prescription omega-3-acid ethyl esters (P-OM3) often are used for hypertriglyceridemic patients receiving statin therapy who have residual increases in atherogenic lipoprotein lipid levels. To date, limited information has been published regarding the effects of omega-3 fatty acid consumption on lipoprotein particle concentrations.


We evaluated the effects of adding P-OM3 4 g/d to an ongoing regimen of simvastatin 40 mg/d on lipoprotein particles (P) in subjects with hypertriglyceridemia.


Data were analyzed from the multicenter, randomized, double-blind, placebo-controlled Combination of Prescription Omega-3s with Simvastatin (COMBOS) study. After an 8-week simvastatin lead-in, 254 subjects received P-OM3 (n=122) or placebo (n=132) for an additional 8 weeks. Nuclear magnetic resonance spectroscopy was used to assess lipoprotein concentrations and sizes. Remnant-like particle cholesterol, apolipoprotein (Apo) CIII, Apo AI, and lipoprotein-associated phospholipase A2 (Lp-PLA2) levels also were measured.


Compared with placebo, P-OM3 reduced mean very-low-density lipoprotein (VLDL-P) size and increased low-density lipoprotein particle (LDL-P) size (P < .006 for both) without altering high-density lipoprotein particle (HDL-P) size. P-OM3 did not significantly change total VLDL-P or LDL-P concentrations relative to placebo, but large VLDL-P and intermediate-density lipoprotein particle (IDL-P) concentrations were lowered (P < .01 for both), and the large LDL-P concentration was increased (P < .0001). HDL-P concentration was reduced (P < .0001) as the result of a decrease in medium HDL-P. Remnant-like particle cholesterol, Apo CIII, and Lp-PLA2 concentrations were reduced compared with placebo (all P < .003).


P-OM3 induces changes in sizes, concentrations, and compositions of lipoproteins that may have relevance for the atherothrombotic process.

To evaluate the safety profile of extended-release niacin/laropiprant (ERN/LRPT), pooling data from studies in the clinical development program.


Data were pooled from three active- or placebo-controlled phase 3 studies and three 1-year extensions of phase 2 studies that ranged from 12 to 52 weeks (N = 4747): ERN/LRPT = 2548; ERN or Niaspan® (ERN-NSP = 1268); or simvastatin or placebo (SIMVA-PBO = 931).


The safety and tolerability profile for ERN/LRPT was similar to that of ERN-NSP, except for fewer flushing-related adverse experiences and discontinuations with ERN/LRPT than ERN-NSP. The incidence of consecutive ≥3x the upper limit of normal increases in alanine aminotransferase and/or aspartate aminotransferase was numerically (but not statistically) greater with ERN/LRPT (1.0%) than ERN-NSP (0.5%) and similar to SIMVA-PBO (0.9%). Elevations were reversible with therapy discontinuation and not associated with clinical hepatotoxicity. There was no evidence that ERN/LRPT administered alone or concurrently with a statin had adverse effects on muscle. ERN/LRPT and ERN-NSP produced small median increases in fasting blood glucose levels (∼4 mg/dL) after 24 weeks of treatment, consistent with known effects of niacin.


The favorable safety and tolerability profile of ERN/LRPT for up to 1 year supports the use of LRPT to achieve improved therapeutic dosing of niacin, an agent with comprehensive lipid-modifying efficacy and shown to reduce cardiovascular risk.

  Our topic is the evaluation and treatment of obesity in the practice of medicine. I am joined by Dr. Harold Bays who has carried out many studies of dietary and medical interventions in patients with obesity. I am also honored to have Dr. George Bray who is known for his many years of research into causes of obesity and its therapy. Our goal is bring this clinical and research experience to bear on the office practice of medicine.
